GET+POST in same form?
October 26, 2006 9:02 AM   Subscribe

Is it possible to set the action attribute of an HTML form, such that the method is POST, but the action includes GET variables?

For example, I'd like the following code:

<form name="edit_name" action=".?debug" method="post">
<input type="submit" value="Edit">
</form>


to return GET value containing debug and a POST value containing Edit.

Is this reasonable or possible?

It’s possible, sure. That syntax won’t work, though; you’ll need to give the path to the page, which probably isn’t a single dot.

If you’re using something proprietary as a server-side language, they may not have support for it, because it’s not really idiomatic. PHP and Perl certainly do, and I would be shocked if Ruby and Python didn’t. But that wasn’t your question :-) .

Doesn't seem to work, even with a fully-specified path in the action. Only the GET variable gets through; POST is empty. I'm using PHP.

Yeah, the HTML you posted isn't quite right.

Try this:
<form name="edit_name" action="this.php?debug" method="post">
<input type="submit" name="myfield" value="Edit">
</form>


The problem was your input button didn't have a name attribute. Now, after clicking edit, your PHP $_GET superglobal should contain the 'debug' field, with no value, and $_POST will contain the 'myfield' field, with value 'Edit'.

I'm a dummy; thanks so much.

Out of curiosity, why would you want to mix GET and POST? Wouldn't it be easier (and less hacky) to just use POST for all the variables?

<input type="hidden" name="debug" value="whatever">

I'd like to be able to debug variables "on the fly" as I write methods, whether or not I've triggered a form.

You can also get away with just ?foo=bar bit:

<form name="edit_name" action="?debug" method="post">

The browser (well, Firefox and IE, at least) will construct the URI appropriately, saving you a little URL munging.

FWIW you can also do "./?blahblahblah" if you want to be both explicit ("I want to access the same URL/resource that I'm currently at") and terse.
