[RESOLVED] EASY form question

[OniLink]

Hi,

I have a form with two buttons "Yes" and "No". I want to know how I determine which one has been pressed for the form action.

I've tried using the following to determine if "No" was pressed, but it doesn't work:

<form id="Form" name="Form" method="post" action="<?php if (Form("submit") == "No") {echo "index.php";} ?>">
<input name="Yes" type="submit" value="Yes" />
<input name="No" type="submit" value="No" />
</form>

Thanks for any help,
~Oni.

PHP cannot detect what has been clicked until the sever receives the response, which is after the form has posted. You may want to use Javascript if you want to do detect what was pressed and determine what should be done. If you want to use javascript you will need to use an onsubmit event in the form.

Or, just have the form submit to one script regardless of which button was pressed, and do your handling inside a PHP script:

<?PHP

if(empty($_POST)) {
     // nothing posted, redirect to form with error message maybe?
} elseif(isset($_POST['Yes'])) {
     // they pushed yes
} else {
     // they pushed no
}

Thanks heaps. I'ce got one more question...

I've got a form with numerous textfields. I've got the action to point to a php file once the form is submitted. My question is, how do I use the textfield values in the php file? How do I refer to them?

Thanks.

If you have texfields(or do you mean textareas?). Anyway with both you just point it with $_POST like this

Form:
<textarea name="var">Some text</textarea>

That would be $_POST['var'] in php.

Same with text type:
<input type="text" name="var" value="Some text">

That would be $_POST['var'] in php.
