[SOLVED] I need simple information about POST methods

[plodos]

If I POST variable with this method, where like = '%%' query is not working

<?php
$var = $_POST['search'];

but if I post with like that where like = '%%' query is working (somebody give me this code)

<?php 
$search = (isset($_POST['search'])) ? $_POST['search'] : $_GET['search'];
$search = trim(mysql_real_escape_string($search));
?>

 

What is the meaning of this sentence ???

<?php (isset($_POST['search'])) ? $_POST['search'] : $_GET['search']; ?>

 

and what is the difference between these methods?

Hi. I am no expert, but I learned a fair bit from these pages.

I hope these help.

If post[''] never worked,then get[''] did, meaning your getting the search info from a url.

 

if u need a brake down, off your code, and don't understand, then tell me then we will explain.

Thanks for urgent reply.

Could you explain this code word by word,

what does it stand for ( ? : )

<?php (isset($_POST['search'])) ? $_POST['search'] : $_GET['search']; ?>

[Mikedean]

<?php (isset($_POST['search'])) ? $_POST['search'] : $_GET['search']; ?>

 

It's an IF statement (I can't remember what it's called), so it checks if '$_POST['search']' is set, if it is, then it sets '$search' to $_POST['search'], if not then it sets it to $_GET['search'].

 

It's just like using IF (BLAH) { } else {} but it's a lot cleaner .

 

Hope this helps .
