function() with form submission?

vaska

This is probably a dumb question really, but I haven't really found an explanation about how to do this...

How do I put a post or get (submitting a form) inside of a function?

You know, something like this:

function submitTheForm () {
global $name,$lastname,$etc;
if (isset($_POST['something'])) {
do stuff...
}

I'm not sure how to access the function() from the submit procedure (the actual "input" submit)...I haven't been able to make it work or even find something that could explain this...

??? 🙂

document.formname.submit();

replace formname with the name of the form.

Isn't that javascript?

I'm not clear on what your exact problem is; wouldn't you just call the function?

PHP isn't client-side, so you can't call a function without having it reload the page... you could use javascript, but you can't call a PHP function with it, you'll have to do it in Javascript.

You could obviously submit your form with a hidden variable like the following:

Add this to your form:
<input type="hidden" name="submitted" value="yes">

Then on your next page:

<?php if($submitted == "yes"){yourFunction();} ?>

If you changed your form's action to:

action="<?php echo $PHP_SELF;?>"

Then it'll submit the page to itself (basically just reloading the form but including the variables.

I still think you'd be best using Javascript for what you're doing, but we don't really know what you are doing.

Aha! I think this is what I've been looking for. Logically this makes all the sense in the world to me, but I wasn't arriving to this same conclusion.

I was trying to find out (since I'm confusing everybody due to my inability to ask the right question) how to properly code a function into a form submission. I was trying to put the "if ($submitted)" inside of the function, but I didn't feel like that was correct.

But if anybody has any other techniques for achieving the same as the above I'm certainly open for learning more stuff.

Thanks very much everybody...v

From reading your original post, I thought you were trying to call a function without reloading the page, which you'd need to use Javascript for... there are a couple different ways of doing it, but play around with it (that's how you learn).
