Determining which submit button is pressed

Ch3vr0n

Hey folks,

I've got this script i've edited a little that when it's finished running outputs a couple lines with on each line a submit button (each have their own name ofc)

The thing is that those submit buttons all point to the same document, but depending on wich submit button is pressed the text variable (from a hidden text field) that needs to be processed changes. The text in the variables gets processed to the processing page as a simple echo works. I need to know how i can determine wich submit button is pressed.

Probably has something to with isset i think but i've got no idea what and how.

in your submit buttons you'll have something lke this:

echo "<input class='subbtn' type='Submit' name='subbtna' value='Submit me'>";

in your $_POST array you can then do

if (isset($_POST['subbtna'] && $_POST['subbtna']=='Submit me') ) echo 'subbtna clicked';

if you have lots of buttons then this format is better

name='subbtn[]'

then you check the $_POST array of 'subbtn' to get the id of the button pressed

Not exactly. The submit buttons is on simple html code. no class is beling used

echo 'couple table rows & td's and after a few lines <input type="submit" name="submitaa" value = "Confirm">';

Then a few lines further another submit button but with the name like "submitab"

The current amount of submit buttons is half a dozen and this amount is likely to increase.

so whats the best and fastest way to determine in the form processing php page wich submit button is pressed and then proceed with the processing.

class has nothing to do with it - ignore it, it's just css styling of the button

to get the name of the button being pressed do this, as I mentioned:

if (isset($POST['submitaa'] && $POST['submitaa']=='Confirm') ) echo 'subbtna clicked';

do that for each button, at the place where you process your $_POST values
(which might be the top of the page or you may have the specified a script in your form action)

that will give you the name of the button pressed

is your form method GET or POST??
if it is GET change $POST to $GET

So if i understand you correctly i need that isset line per button but instead of doing that echo process the variable from the hidden text field ? then repeat that code for each submit button but change the submit button names to match the ones from the document that has the buttons ?

Form method is _POST

Since i can't edit ill add another reply. Forgot to add that the processing document starts like this. Setting new variables throught the posted $_POST Variables.

$submitaa=$_POST['submitaa'];
$submitab=$_POST['submitab'];

After that i need to do that isset line and then repeat that section per button ?

cretaceous

yes - that should do it
