javascript submit() not setting $_POST data!

aewarnick

Is this a common problem with javascript:submit()?
I'm creating this form dynamically when the user wants to remove some images and change image descriptions with this code:

<script type="text/javascript">
<!--
function SubmitChanges()
{
	document.write("<H2>Processing...Please Wait...</H2><form name='javascriptSubmitForm' method='post' action='\''+document.submitPath.value+'\''> <input name='Cat' type='hidden' value='\''+document.Cat.value+'\''> <input name='start' type='hidden' value='\''+document.start+value.'\''>");
	var delOk= 0, asked= 0;
	for(var f=0; f<document.forms.length; ++f)
	{
		if(document.forms[f].name=="editForm")
		{
			document.write("<input name='im[]' type='hidden' value='\''+document.forms[f].im.value+'\''>");

		if(document.forms[f].desc.value.indexOf('<') != -1 || document.forms[f].desc.value.indexOf('>') != -1)
			document.write("Illegal Character<br>");
		else
			document.write("<input name='desc[]' type='hidden' value='\''+document.forms[f].desc.value+'\''>");

		if(document.forms[f].cb.checked)
		{
			if(!asked) {asked= 1; delOk= confirm("Press Ok to DELETE selected images");}
			document.write("<input name='del[]' type='hidden' value='\''+delOk+'\''>");
		}
	}
}
document.write("</form>");
self.javascriptSubmitForm.submit();
}
//-->
</script>

When it is sent to the server, php evaluates and
if(isset($_POST['javascriptSubmitForm'])) is always false.

And what does

<?php
print_r($_POST);
?>

say?

Array ( [Cat] => [start] => [im] => Array ( [0] => [1] => [2] => [3] => [4] => [5] => [6] => [7] => [8] => ) [desc] => Array ( [0] => [1] => [2] => [3] => [4] => [5] => [6] => [7] => [8] => ) )

Looks like nothing is set but I KNOW the javascript variables are good because I tested them.

Well, yes; the Javascript variables are set as far as JS is concerned, but apparently they're not being POSTed to the server via the HTTP POST protocol....

Thanks for your help. Anyone have any idea why this isn't working?

dalecosp

Well, the most likely reason is that they aren't part of a form, or the form has the wrong attributes....

I'm being lazy about Javascript at the moment, but surely using getElementById or even using the older method of using the form's name to look it up in the array directly would be a lot simpler than building a loop to go through every form on the page until the right one is found?

In fact, why create a new form just to copy values into it from another form just to submit it?

Whatever is going on on the client, this looks like an overly complicated way of going about it. But, seeing as this has yet to have anything to do with PHP, I've got no more comments on it.

It was my html that was the problem. Quotes can be awfully confusing. Thanks guys!
