PHP :: Conditional Loop

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>

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?";
?>

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:

Writing Conditional Statement
I'm trying write a conditional statement that updates the database in 1 of 2 ways depending on the values given. I'm only 2 weeks into learning PHP/MySQL so I realize the way I've written it out is probably sloppy and more inefficient than what it could be. I've just been winging it from examples and trial and error and have gotten everything working except for this. I'm not sure if I have my logic or syntax wrong.

Application-specific details:
This is a simple invoicing application. Every invoice is in either 1 of 3 states:

- pending (default state when a new invoice is entered)
- paid (state when invoice is paid in full)
- partial (state when only partial payments have been made on the invoice)

What I'm trying to do is this:

1. If a partial payment is made on an invoice, the status is set to 'partial' (this is working)
2. If the payment posted was the full amount of the invoice or the final amount needed to pay it in full, the status is set to 'paid' (this is not working)

My processing logic works like this:
1. There is a total invoice amount stored in the invoice table represented by $total variable (working)
2. When payments have been made to that invoice (stored in the payments table), I show the remaining balance on their invoice by calculating the sum of those payments and subtracting them from the total (this is represented by the $diff variable and is working)
3. The part not working: When the remaining balance ($diff) minus the payment amount posted ($_POST['amount']) is equal to 0, the status is set to paid. PHP Code:

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);

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>

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:

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.

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";}

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?)

Creating Table Rows For Ever Other Loop In A WHILE Loop
I'm trying to create a table using a MySQL fetch array while loop that would look like this:

CONTENT1 CONTENT2
CONTENT3 CONTENT4
CONTENT5 CONTENT6

I need a <TR></TR> for every other piece of content. But I don't know how to do this with a loop that uses a MySQL fetch array

while($row = mysql_fetch_array($result, MYSQL_ASSOC))

{
PHP CODE THAT IS LOOPED;};

I'm trying to remember from my old college Java class that we did something with loops for whenever the counter variable was even the loop would do something special... I don't know if this is possible with a while+mysql_fetch_array loop though.

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.

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:

Creating A For Loop Inside Another For Loop.
I'm trying to write a script that will display questions that are in one flat file and answers from another flat file. In addition, there are copies of these files with their own data in multiple folders.

I created a for loop to work with an array of the different file paths to the different folders. Then I created a for loop inside of that one to display the questions and answers files that is in each folder. All I get when I run the script is the first folder and it's questions and then it stops there. PHP Code:

Get A Varable To Loop Out Side The Loop

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.

For Loop In PHP

For Loop Q
I have a "for loop". In this "for loop" a variable called $reg is set.
Each iteration of the "for loop", $reg is assigned to a new value.
My question is: how I can store the values of $reg each iteration in an array?

Below is some pseudocode, which I hope further illustrates what I mean.

$count = 60;
for ($i = 1; $i <= $count; ++$i) {
$reg =
}

This has got me a bit stumped.

After I have managed to make the array.
I would then like to explode this array out into variables - each one assigned a value of $reg

I realise that this may be quite a basic Q. And i really do apoligise. I have read up on arrays and am having trouble applying it to this
situation. Thanks very much.

P.S A further complication that I would like to accommodate is that $reg may be assigned a number of values in a single "for loop". I would like to
collect all these values.
The pseudocode for this:

$count = 60;
for ($i = 1; $i <= $count; ++$i) {
$reg =
$reg =
}

If this post is difficult to follow - dont hesitate to post back and I will try my best to expand. It is just I didnt want to make this post too long and
put people off.

P.S It may be helpful to know what is actually in the "for loop":

for() {

$regex = "/(([A-Za-z0-9]+_+)?[A-Za-z0-9]+-+)?[A-Za-z0-9]+.+)?[A-Z
a-z0-9]+++))*[A-Za-z0-9]+@((w+-+)?w+.))*w{1,63}.[a-z
A-Z]{2,6}/";
preg_match_all($regex, $data, $reg))

}

Using A While Loop In A For Loop - Can This Be Done?
can you use a while loop inside a for loop; without contradicting or excluding your for loop? I would test it myself; except my server is having Server Error 500 issues right now. so I am not able to do a trial and error test at this time.

something like this:

for ($x = $skip2;$x<=$pagedisplay;$x++){
while ($myfield != $maxed_out) {
echo " <a href="". $_SERVER['PHP_SELF'] ."?skip=$x">". ($x+1) ."</a> ";

I´m trying to make an application to insert new data into a table. So i extract the fields of the table and let the user introduce new values. The problem is when i´m trying to put them into a table.

Firstly i get the new data sent via form with a while loop, because the number anda name of the fields can be different in each case. I do it like this

$sql = " SHOW COLUMNS FROM " .$_SESSION["nomtab"]. " ";

$res= mysql_query($sql);

while($row = mysql_fetch_array($res))
{

$$row[0] = $_POST["$row[0]"]; }

Now i introduce correctly the first´s field value and i create two auxiliar variables $primercampo and $valorprimercampo which contains the name of the first field and its value, so i can use them later to update the values, it goes like that Code:

I'm trying to add the following link to my display page.

<a href="applyforstake.php?item_id=1>Apply"

This is the code taken directly from the display page:

echo "<td>"."<a href="applyforstake.php?item_id=1">Apply"."</td>";

This code works well for displaying the link in my display page, however, I want the item_id to be equal to the auto_increment column on each row. In other words, for the first row on the display page, the item_id will be 1, the second row item_id should be 2 and so on for however many rows are in the table. How do I accomplish this.
