$_GET and $_POST errors

[jimbobiv]

How can i hide these errors,

for example:

$name = $_POST['name'];
$primary = $_POST['Primary'] ;
if ($primary=='') $primary='OFF';
$alliance = $_POST['Alliance'] ;
if ($alliance=='') $alliance='OFF';
$tournament = $_POST['Tournament'] ;
if ($tournament=='') $tournament='OFF';
$limited = $_POST['Limited'] ;
if ($limited=='') $limited='OFF';
$FFA = $_POST['FFA'] ;
if ($FFA=='') $FFA='OFF';

There is my code, $name is always entered so i dont need to check for it, all the others are information for check boxes (checked or unchecked) if unchecked there is no information, so how do i stop the annoying error coming up when the PHP tries to retrieve info from the POST taht doesnt exist... i have tried

(if $_POST['FFA']) $FFA=$_POST['FFA'];

but i get the same errors.. is there a way of either storing the errors as a variable (and then ignoring them) or perhaps telling the $_POST command not to return errors?

Cheers guys (and gals)

I'm assuming you mean php says stuff like non existent index or something. When you submit a problem give as a clue !.
I reckon though you need to look at the function isset()

POST is not a command, it's a superglobal array.

What I believe you actually want is to know if a specific array key exists

http://us2.php.net/manual/en/function.array-key-exists.php

Or as ingresman suggested, you could also check to see if the particular value isset

http://us2.php.net/manual/en/function.isset.php

And just for fun, the actual question you asked, is one I always hesitate to answer... but you can hide the errors using the @ operator, but you almost certainlly don't want this, you can read why here

cheers, and to ingresman, its obvious what the fault would be from the code i showed... sorry if i didnt explain it properly but like

i=3 i get an error, well der u missed a dollar, dont need to put what the error is ;o)

anyways, i'll read those articles when i have a second!

Hi,

This would work just fine :

$FAA = $_REQUEST["FAA"];
if(!$FAA)
  $FAA = "OFF";

You need to be careful. If $FAA exists but has a legitimate value of zero, PHP will in examining !$FAA convert the value to FALSE. This could lead to unexpected behavior from the script.

Also, don't use $_REQUEST. It has some of the same security problems that you can have with setting register_globals to "on". Be specific -- use $_GET, $_POST, $_SERVER, $_COOKIE, $_SESSION as they are the most specific.

I have already found that problem, with the 0 value thing, thats why im not using that, i have solved the problem using the isset rule, thanks guys...

 

[ingresman]

Sorry, I've been doing PHP for so long I never assume anything !even when a couple of lines of code are presented rather than the actual error.
ho hum
