From my understanding isPostBack is a ASP.net property which indicates whether a PostBack occurred. For PHP you need to use a boolean which determines if your statement is true or false.

Try something like this: I am still learning PHP so if this isn't right don't be upset...



if ($answer1 = true) {
print "The answer is true";
}

if ($answer2 == false) {
print "enter something here";
}

'Postback' is a particularly hideous method ASP.NET has of passing data around between page requests. Basically it involves having Javascript submit a hidden form every time the user clicks a link.

The equivalent for your purposes is probably to use a session. If you just wanted to handle POST requests, then simply check whether the POST variable you want is available (remember, GET and POST aren't entirely mutually exclusive: it's possible to POST to an URL that has query data tacked onto the end of it).



if ($answer1 = true) {
print "The answer is true";
}Careful — that will always be true. You probably meant == or, better, ===.

thank u 4 ur reply...

but wat i actually want is.. durin the FIRST page load i want to execute a set of code.. but tis code should nt be executed wen a button in tat page is clicked..

So you just want to run some code? That's done simply by putting the code on the page (inside a <?php ... ?> block).

You may also want to make sure you spell everything correctly.

@Twey..

if i write the code in <?php .. ?> block, it will be executed everytime when the page is loaded..


ok friends.. thank you for your replies.. i have made another solution for this problem... :)

You mean the first time the user requests the page? Then, as I said earlier, sessions are the way to go:
<?php
session_start();

if (!@$_SESSION['something_done']) {
do_something();
$_SESSION['something_done'] = true;
}
?>
