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:

Structures In Php ?
How do you create data structures in php ? i.e. how would I create the following two vb structures in php ? Structure SYSTEMTIME Dim wYear As Short Dim wMonth As Short Dim wDayOfWeek As Short Dim wDay As Short Dim wHour As Short Dim wMinute As Short Dim wSecond As Short Dim wMilliseconds As Short End Structure Private Structure TIME_ZONE_INFORMATION Dim Bias As Integer Dim StandardBias As Integer Dim DaylightBias As Integer Dim StandardDate As SYSTEMTIME Dim DaylightDate As SYSTEMTIME End Structure Also, if I read a binary value from the registry, how would I then convert it to a variable of type TIME_ZONE_INFORMATION
Data Structures
Is it possible to create data structures in PHP and if so, would someone provide a bried example? Example: I would like to create a Data Structure JRec which has the following fields lID (Long) dtDate (Date) sName (10 Character String)
Control Structures
I was just wondering. Im submitting a form, using this code: if ((!empty($_POST['Name']) || !empty($_POST['E-Mail']) || !empty($_POST['Question'])) { code... } What im testing for is if name, email or question is set, do the following. But it is not working, do I have the syntax right?
Dynamic Directory Structures
I need to translate the path /category_name/sub_category_name/ to /category.php?sub_category_id=2 without redirecting the user. There seem to be many ways of doing it, but with my current web hosting provider (E.N.E IT - www.eneit.com) there are some constraints. For example I cannot modify the httpd.conf. However, I've got the functionality provided by CPanel (e.g. AddHandler's) and I can create .htaccess files. I've read a little about the RedirectRule command in Apache, but it does not seem to work due to that I'm on a shared hosting server. I've also realised that I could do /category.php/category_name/sub_category_name/, but haven't found a way to remove the .php in that instance.
Reading C Data Structures
I have a file duplication progam I wrote years ago in C on a Unix system. I open up zip files and store CRC info in my own database. It's a great application for php/mysql and I would like to learn php/mysql in the process of moving it over. Can someone tell me how you would read the header (data structure information with all the fields) on a zip file (in this case its the localheader right after the signature), so that all the fields of the structure land nicely in an array in php? I'm attempting to use freads/fseek to each field and this just can't be right. Doesn't matter what data structure I just need to know the most common method you use to open a file in read blocks of data and unpack them back into a data structure.
Select Count Query, 2 Tables With Identical Structures
I have 2 Tables that have the exact same structures, One is for Inventory, the other is for Relief Inventory (ie. when an item is sold it is moved to relief). What i want to be able to do is to run a query that will count the number of items tested by one person and display that sorted and grouped by the date cleared. I can get this to work when working with just the Inventory table, but the problem is that as items are moved out to relief the counts will change. $query = "SELECT COUNT( * ) AS `Count` , `Date Cleared` , `Tested By` FROM `Inventory` WHERE `Tested By` = ".'"'.$tester.'"'." GROUP BY `Date Cleared` ORDER BY `Date Cleared` DESC "; My question is, how do i run a similar query that will search both tables and combine the results. I have tried adding the other database to the FROM statement, and have been tring to figure out if i can use a join statement but that hasn't yielded any favorable results.
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 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?"; ?>
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.
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?)
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:
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.
