[SOLVED] two submit buttons on one form and detect which one is pressed..?

[Dragen]

Hi,

My first question is more html than php but it links in with my next question so...

Is it possible to have two submit buttons on one form? I would use different names for them, one being name="submit" and the other being name="reset"..

Please note that it's not a reset button in the usual sense. I want it to submit the form as a submit button would, but as it's carrying a different name I want it to make the output different. They would both be type="submit"

 

This leads onto my second question.. is it possible to detect what the name of the submit button is?

I guess if I have two I could use something like:

<?php
if(isset($_POST['submit'])){
// code here
}elseif(isset($_POST['reset'])){
// code here
}
?>

 

would this work?

If you are trying to use 2 Submit Buttons you can use 2 separate forms for separate Submit Buttons.

e.g. <form><!-- Submit1 Button here --></form>

<form><!-- Submit2 Button here --></form>

And 2 form action will be Different or same.php?form=1 and same.php?form=2

thanks. It seems to be working how I thought though.. with the isset().

At the moment I've got:

<?php
if(isset($_POST['submit'])){
echo "submit";
}elseif(isset($_POST['reset'])){
echo "reset";
}else{
echo "<p align=\"center\">error: unspecified action</p>";
}
?>

which seems to work as when I click on the submit buttons it echoes the correct statement.

I'll have to see how it works once I add all my code in though!

The other way to do this is to give each "submit" button the same name, but different values:
[cpde]
<input type="submit" name="submit" value="Submit">
<input type="submit" name="submit" value="Reset">

 

Then in your script:

<?php
if (isset($_POST['submit']))
    switch($_POST['submit']) {
        case 'Submit':
               echo 'The "Submit" button was pressed';
               break;
        case 'Reset':
               echo 'The "Reset" button was pressed';
               break;
        default:
               echo 'Problem with the submit button -- wrong value -- ' . htmlentities($_POST['submit']);
               break;
   }
?>

thanks.

Would this that method be any better.. in respect of cleaner code, faster loading etc?

I think the "Switch" statement is easier to understand than many if-elseif-else statement. It's also easier to add more conditions. YMMV.

yeah, I see your point. Thanks for the advice!
