PHP :: Writing Conditional Statement

MySQL Conditional Statement
What I am trying to do is kind of like an advanced search. Basically, I have three dropdowns, for this I am going to use the example books: Three dropdowns, which are

1) Author
2) Language
3) Type (Hardback or Paperback)

Typical search: I want to get a list of all books written by STEPHEN KING, that are written in ENGLISH and that are HARDBACK ok fine, but what if I just want to search for ALL books by STEPHEN KING regardless of the language or the type of book?? Heres the SQL i would use for all 3 "search parameters": PHP Code:

Help With Posting Conditional If Statement
I've tried scaling down a script to the bare minimum and
it still is not working correctly. What I think should happen is that when
the field app_fname is blank, that $hold_chk will get set to 1 and the 1st
if statement will be executed. What actually happens is that when I hit
submit, the form stays where it is, for example if the form where the submit
button is located is on the form other.php, then when I hit submit this is
where it stays. If I then hit the submit button a 2nd time, it post to the
some.php form. I've tried this script without the conditional if(isset()
and it works. I need to have the isset() otherwise the form displays all
empty fields as soon as it loads, before the submit button is hit.

<?php

$holdchk = 0;

if (isset($_POST['B1'])) {

echo "<br><br><br>";
if (empty($_POST['app_fname'])) {
$holdchk = 1;
}

if ($holdchk == 1 ){
echo "<form method="POST" action="some.php">";

}

if ($holdchk == 0 ){
echo "<form method="POST" action="other.php">";

}
}
?>

<html>

<head>
</head>

<form method="POST" action="">

When
hit the submit button</font></b<input
type="submit" value="Submit" name="B1"></p>
</form>
</body>

</html>

Simplifying A Basic If Statement Conditional
Is there a more efficient way to write this:
if($var=1 || $var=4 || $var=27 || $var=28 || $var=30 || $var=37||
$var=38){echo "true";}

Conditional Statement For Default Case
I'm trying to create a conditional statement for my menu that will check to see if the page is on the default case. Code:

Syntax Issue With Form And Conditional Statement
Is it possible for a <form ... action="program.php"> to contain a conditional statement for the action? For example, I want to call one PHP program if variable $a="screen" and another program if variable $a="download". I have been struggling with this for some time and cannot seem to get it to work.

Conditional Loop
I have one table, "players" that has player info including start season (year). I then have a table for each season with player stats, i.e. games played etc called stats200X where X is the year obviously.

I have no problem with extracting data from the current year, but what I would like to do is get data from previous years too. I was thinking about doing something like:

(year) - (startyear), which for example could be 3.

I don't know where to begin, but I want to be able to loop though previous years so that, if tables exist of course, I could do

select * from stats{Y -1}
display
select * from stats{Y -2}
etc

Would I need to hard code this or is there a way of doing this though a conditional loop?

Conditional Login..
I have a form with a username & password field along with 3 radio buttons.

What I basically want to achieve is if radio button A is checked it will post the username & pass to a.php, If button B is checked it will post the username & pass to b.php and so on for button C.

Checkboxes,conditional
Basically I have what seems to be a very small problem but I am driving ny self mad trying to figure out what the problem is. Here is what I have: I have a form with two checkboxes:

<input type="checkbox" name="medicalcheck" >
<input type="checkbox" name="dentalcheck" >

the form is posting the a php file, decision.php, that simple checks to see if the boxes have been checked and performs an operation in either case. Here is the code:

Once Conditional Causes Error, The Other Doesn't...why?
There are 2 if statements at the beginning of this code snippet. The one that is currently commented out works while the one that is not commented out yields this error

Parse error: syntax error, unexpected '{' in C:xampphtdocsench2index4.php on line 106

I am just not seeing why. Code:

Conditional Structures
I am wondering about conditional structures and the depth of nesting allowed, if at all. For example I know I can do this: Code:

Conditional Form
I want to condtionally display an HTML form. I havnt got a clue how it can be done, I suppose its the same way as putting html tables in php, but I cant get it to work. Here is the condtion:

<?php
if (!empty($pk))
{

And here is the form:

<form action="google.php" method="GET" name="deleteForm" >
<input type="hidden" name="pk" value="<? echo $pk;?>">
<input type="submit" value="Delete">
</form>

Conditional Third Expression In For Loop
Is it possible to make expr3 $i++ under one condition and $i-- under another? Instead of having the condition outside the loop and having two loops. Or I could just use a while loop, I guess.

Sessions + Conditional Include
I am having a little problem in trying to figure out why my session state is not expiring after I close the browser window. Having been used to the ASP way of doing things I am trying to get my head around this slightly different method of handling sessions in PHP....

What happens is that I log on to the site, do various things and then close it when I am finished. I return the next day to find that the 'logged in' menu is displayed first which shouldnt happen until you have logged in again.

I assumed that the session was been stored as a cookie but wasnt been released after the session terminates by default, but found I was wrong when I deleted all my internet files and went back to the site.

My code for the first page is as follows..

Conditional PHP Cookies; If Cookie = 1 Do This...
I've figured out cookies ... now I'm trying to combine them with if conditions.

For cookie 'bandwidth1' I want to echo that it is set to 1 by the cookie to confirm this in the brower through regular html.

My if/else statements don't seem to be working though...heres the code I have now.

<?php
setcookie("bandwidth1","0",time()+2592000,"/");
setcookie("bandwidth2","1",time()+2592000,"/");
setcookie("bandwidth3","2",time()+2592000,"/");
?>

<?php
if (isset($_COOKIE["bandwidth1"])=="1")
echo "Bandwidth is 1!";
else
echo "Bandwidth is unknown";
elsif
echo "Cookie was not set?";
?>

Conditional Statements And Loops
Not long ago I was asked to give PHP lections to some private IT
school. I'm on second lection now, and will be teaching my :) students
conditional statements (if..else and switch) and loops (while and for).
That was my story, now the question.

Can you give me an advise on some geeky use of those statements to stir
up some enthusiasm in students.

Mutlipart And/or Conditional Form
I have a form that needs to have conditional statements, and I am not sure how to "fix" this. The existing form is split in two parts - the form, and the processor. I would think that I will need to combine them, but..

Anyways - what I need is somewhat simple - if a certain option (from a <select>) is chosen, force another field to be completed. I also have 2 other fields that if the radio button is set to YES, require new fields. Ideally, the optional fields would only be shown to the user IF they are required.

Conditional Select From Mysql
I have a mysql database which stores race data that I want to open up to users for viewing. I want the user to be able to select various subsets of the data according to the parameters: race, gender, age, and type (and maybe sometime, by name as well). This is BOTH a mysql question and a php one, as I ask for a more efficient solution (see bottom this post).

Here is a snippet of how I am implementing the mysql statements to select only the exact subset of data. PHP Code:

Conditional Preg Match
The following bit of code does a preg match and does something if true
(sets $browser to ppcie)

Without using if then and else's how do I code it so it does not equal
what it is testing for? So if it does not find ppc in the $agent then
it does something else/sets it to something else?

$agent = getenv("HTTP_USER_AGENT");
if (preg_match("/PPC/i", "$agent")) {
$browser = 'PPCIE'
}

Question On Conditional Statements
I'm a perl programmer and am trying to learn PHP.

So far I have figured out most of the differences, but have not been able to
find out how to do the following:

When running through a loop, how can you test two separate conditions
against the same $element of an array. For example, this is how I thought it
would be done (similar to Perl), but it did not work:

if (eregi("apple", $line) and (eregi("orange", $line) {

do whatever;

}

Basically testing each line of an array to see if both the words "apple" and
"orange" are present.

Also, is there any equivalent to the following from Perl while running
through a loop:

next if (whatever conditions);
last if (whatever conditions);

Conditional List Boxes
I am attempting to create a list box that is dynamically populated based on the selection of another list box. I am in way over my head..only way to learn I guess. The code below has a year listbox and then based on the year selection, the page should either show another listbox (show industry selection when year <> 2005) or it should render the main form (when year=2005). I cannot get the main form to appear. Code:

If Statement Construction Within An Echo Statement
I have a form that is being used to "update" user info and I need the information to be pulled from the users table. In order to get the variables into the form, I am echoing it in and using an mysql array to place them into the form.

at the t-shirt size part of the form the code is as follows ....

Conditional Email Text To Hyperlink
I am trying to write a content management section for a web site.

I have managed so far to use htmlarea to give users a basic, but user
friendly interface by which to edit the page content.

The user can add emails by symply typing john@example.com - IE automatically
converts this to a hyperlink. The trouble is sometimes the users use plain
text. I have been using the following line to convert plain text to a
hyperlink:

$pagetext=ereg_replace('[A-Za-z0-9_]([-._]?[A-Za-z0-9])*@[A-Za-z0-9]([-.]?[A-Za-z0-9])*.[A-Za-z]+',
'<a href="mailto:?subject=Email%20from%20web%20site"></a> ',
$pagetext);

This works well - BUT it completely screws up any existing hyperlinks. Is
there a way to convert the plain text email address in to a hyperlink only
if it is NOT part of a hyperlink.

Basically I need some way of checking
* If it's plain text > convert to a hyperlink
* If it's already an email hyperlink leave it alone.

I have tried looking up and testing everything I can think of - but am
finally asking around before I go mad.

Avoiding Endless Conditional Statements
Here is my problem. I want to make a webapp that will basically take
the work out of finding what tool works for what situation. There are
5 factors that go into tool selection. 1)Material Group, 2)Insert
Radius, 3)Insert Type and Size, and 2 others that I can't remember
off-hand. There are probably about 1000 different scenarios that I
have to code for..(there are several blank table cells and it's not
setup as you might imagine, there is a lot of overlapping), and I
desperately want to avoid making a gigantic conditional statement. I'm
afraid that I really have to provide a picture of what I'm doing here,
so I will do that. Here is the link.
You only see 3 of the 5
factors on this page, and the other 2 have to do with whether this
table or one of many other tables (not pictured) will be used.

So, now that I've confused everyone. That's my table. What's a good
way to go about programming that sucker in so that people don't have to
do all the "work" involved to figure out what tools they need. They
should just be able to choose selections from 5 dropdown boxes and get
one tool back. A tool is something like "10.655.600".

Cascade Dropdown Or Conditional List
I would like to create a conditional cascade form. based on the selection, it can display or not display an input form for the user to enter an string of text. then at the bottom of the page (or when a user submit) connect all the sections including the input field all together (it's like a story maker?)

PHP Conditional Setting Of Radio Button Default
I'm working on an edit inventory form, and I'm pulling a field from my database that's going to be a 'Y' or 'N'. Based upon this, I want to default the 'customizable' radio button to either checked="Y" or checked="N". Code:

Make Function Equal To String In Conditional
I can usually figure something out, but I CANNOT figure this one out: This is a classified word ad script to count the words in a text area ($wrdad) and multiply it by the rate for how many times the ad will run in the newspaper. I know my code is messy and ameture, don't be too critical, but it works - everythign except one part. We have a 15 word minimum. I have this area commented out as //Problem Area/// in the code below.

In a nutshell, I want function wordcount($wordad) to be equal to 15 if there are fewer than 15 words in the $wordad textarea. It just seems to ignore the wordcount($wordad) == 15; in my conditional. Code:

Conditional "implements"
Currently i'm thinking about how to solve this problem:

if (t3lib_div::int_from_ver(phpversion())<5000000) {
// php4
class tx_lib_object extends tx_lib_selfAwareness {...}
//
} else {
// php5
class tx_lib_object extends tx_lib_selfAwareness implements ArrayAccess, Iterator {...}
//
}

The question is now how to make this conditional "implements" in php?
Of cause i do not want to copy the code for both php versions and then
switch between the whole classes.

PHP Writing
Hi,

I'm quite new to php. Actually very new. Anyways... my problem is:

The text from my form is sent to my php file which in turn opens/writes/closes my xml file.

This works great, the only thing that goes wrong is when I write a single or double quote in my text field, php writes ' or " in my xml file.

ie: If I write this into my field:

<teachers>
<teacher name='Bobby Brown' file='bbrown'/>
</teachers>

PHP writes this into my xml file:

<teachers>
<teacher name='Bobby Brown' file='bbrown'/>
</teachers>

Any suggestions?

Thanks in advance.

Writing
I am writing a script. Everything has gone great except I can't figure out for my admin section how to edit and write to just one line of a flat text file.

PHP Writing To /etc
I'm trying to set up a simple web interface to maintain the rules
configuration for Shorewall.

This entails writing to at least one of several root-owned files in
/etc/shorewall.

Can anyone, please explain how I allow a script to write to one of these
files when apache is running as www-run.nobody (on debian stable) ?

I appreciate that it's probably about permissions, but I should like to
be able to minimise the risk of abuse because it is for a charity that I
work for.

Apache is set up to be visible internally only and I shall ensure that
no-one can make it visible via the interface!!

Writing To Xml
i want to know wha tis the best way to write and add to a xml file? Code:

Writing PHP
However, unlike when you add the .html extension when using notepad to write html code, all I get is a notepad icon instead of the IE icon and when I open it with IE or Firefox all I get is a page of html coding.

Which software should I be using to write the code?

Writing To A File
The script below writes to a file and sends back confirmation that all is well. That is working correctly. The problem I am having is when I view the blank data.txt file that I uploaded to the server (and yes, I have put the file permissions to rw-rw-rw) its still blank!!!!!!! despite my little script stating that all is well. The same script works perfectly well on the
totalise server. If the answer is to run the script as cgi I am too sure how to carry out the 7 different suggestions advised at the FAQ. I am OK at saving the script with a .pl or .cgi extsion instead of .php but how do I incorporate the extra line of code(#!/usr/bin/perl?) do I use it everytime I open php in the
script or just once at the start. What exactly is the base path and how do I check to see if it is set correctly. The script in question is: (basically it handles the data(an URL and a description) coming from a html form and writes these to a file(data.txt)

<?php
function WriteToFile ($URL, $Description) {
/* Function WriteToFile takes two arguments--URL and Description--which will
be written to an external file. */
$TheFile = "data.txt";
if(is_writeable($TheFile)){
$Open = fopen ($TheFile, "a");
if ($Open) {
fwrite ($Open, "$URL $Description
");
fclose ($Open);
$Worked = TRUE;
}
}
else
{
$Worked = FALSE;
}

return $Worked;
} // End of WriteToFile Function.

Writing To A File
How would I go about reading and writing from a file? I would like to make a Web GUI for my sendamail virtualhosts.

Writing A .RTF Document Using PHP
Does anyone know how to use PHP to write a rich text format file - or know of a link to an article that explains it?

I'm getting a bunch of user input from a form, and want to slot the values into a .rtf file so that the document can be printed out for signing (it's a contract).

Writing To A File
I am opening a file copying the contents and trying to write the contents into a newfile in a different directory. but its not working.

<?php
if ($handle = opendir('/home/jarntz/cdstuff/files')) {
//echo "Directory handle: $handle";
echo "Files:";
while (false !== ($file = readdir($handle))) {
echo "$file<br>";

$namelen = strrpos ($file, ".");
$name = substr($file, 0, $namelen);
print "$name<br>";

$filename = "/home/jarntz/cdstuff/files/$file";
$fd = fopen ($filename, "r");
$contents = fread ($fd, filesize ($filename));
fclose ($fd);

$ncontents = nl2br ($contents);
$scontents = "Test<br>" . $ncontents;
print "$scontents<br><br>";

if($name){
$storefile = "/home/jarntz/cdstuff/html/" . $name . ".html";
print "$storefile<br>";
$myfile = fopen ($storefile, "w");
$fp = fwrite($myfile, $scontents);
fclose($myfile);
}
}
closedir($handle);

Writing PHP Scripts Without Using ? In The URL
I plan on redeveloping a website using a PHP and MySQL backend, rather than the static HTML files that are in use now, as it is difficult and time consuming to update. Right now, these pages are indexed in Google, and that is a large source of traffic for the site.

Basically, Google will ignore any URL using a "?", that is the primary reason VBulletin and most bulletin boards are ignored on the search engine. Is there any way to write a script like

/script.php?action=blah

Without using a ? in the URL?

Writing To .htaccess
I read "Blocking Badly Behaved Bots" and its predecessor, and I'd like to ask a relatively simple question:

Assuming I already have the bad IP to ban (let's call it $ip), how would I write the IP to the appropriate line in .htaccess, and safely?

I'd like to use a relatively simple script like this one:

<?php
$file = $_SERVER['DOCUMENT_ROOT'] .'/.htaccess'
$fp = fopen($file, 'a');
fwrite($fp, "Deny from".$ip."");
fclose($fp);
?>

But again, I'm not sure how safe this is, and it doesn't write the IP to the correct line. Any suggestions? I know the other anti-bot scripts do this, but it is very (needlessly?) complicated and I have not been able to block the IP in the right line. Please help out a newbie trying to defend his sites vulnerable forms!

Reading And Writing With Php
In my script i have 1 seperate fopen() sequence to read the file, so it can put it into a textarea.
Then i have another fopen() sequence that will the values i have in the textarea, but for some odd reason it doesn't work! I hope I did an OK job at explaing this. But heres my code! PHP CODE:

PHP Writing To A File Help
I am trying to create a script that will take the MYSQl DB details that have been sent from a form and store it in a file for usage at a later stage.

Am I doing this correctly:

Fwrite Not Writing
I am writing my own news system for my website and everything is flat file at the moment.
I've got it all coded out and it works perfectly. However, i'm on the final stages of this, and of course its the Editing / Deleting part. This is where my problem arises.
PHP Code:

Need Help Writing Own Functions
I would like to try writing my own functions, so as to keep some code
within the same PHP file rather than make multiple PHP files.

What I am having a problem is is how to call a function when a php
generated HTML form is "submitted" and to put the variables back into
another function within the same PHP file.

I have figured how to pass variables to a basic test function I wrote, but
not how to call a function within the same PHP file AND from a form.

Can't seem to find any good examples online.

Writing Code.
I want the user to have some setup options such as changing the name variable, emal varable, among other things in an online format. I am not using MySQL with this script.

So what I was thinking was the following, where $name and $email are the name and email variables, and $enter_name and $enter_email are the user input to change these values in variables.txt:
<BLOCKQUOTE><font size="1" face="Verdana,Arial,Helvetica">code:</font><HR><pre>
$fp = fopen($file, "r+");
$write_to_file = "write the excact same code as in variables.txt except change each value to the users input";
fwrite($fp, $write_to_file);
fclose($fp);
[/code]

What I mean (the description you see of $write_to_file) is I want it to rewrite variables.txt with the new input. So, How can I write PHP code in a variable?

Writing To A File
How can I write to a file on a certan line? Like I have a file with 10 rows, I want to change row number 5 without changing the other rows.

Displaying And Writing
How would I be able to take the contents of a form, and write it to a text file, and then, be able to, each time someone submits a form it rewrites over the same text file?

Writing To A File
I have the following code that displays email addresses on the screen and saves them to a file. The problem is, depending on what flag I put for $fp, it either doesn't write or if it does it doesn't overwrite what's there, just appends it. What can I do about this?

Also, on the screen, it displays each record followed by a <br>. In the file, it just displays all the email addresses in a big block. PHP Code:

Writing To Files
Is there something similar to printf for writing to files? Right now, my code is this

function PrintEmployees($input_array)
{
while(list($index, $value) = each($input_array))
{
printf ("%s (%s) %.2f <BR>n",
$value[0],
$value[1],
$value[2]);}}

But instead of printing to the browser, I want to write the same output to a file. How do I do this? Can it be done with fputs?

Php Not Writing To Mysql
Local server is processing php, DWMX is connecting to Mysql db but php is not writing to db. I have tried two different version of form processing with php but neither is writing to db. Have checked Mysql permissions, I'm able to edit the db from dos with no difficulty.

Have been told it could be the hard drive is not allowing me to write to it. Where are the write permissions defined? In php. Apache or windows? This is not producing an error

echo mysql_error();
echo "<br>";
echo mysql_error();
echo "<br>";

Is there other script I could use to make a simple test?
