218612 - an image form submit button whose image is missing submits the form when click, but does NOT submit the name of the image element

Status: RESOLVED DUPLICATE of bug 122238

(Core :: DOM: Core & HTML, defect)

Description

[Christopher Kings-Lynne]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5a) Gecko/20030728 Mozilla Firebird/0.6.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5a) Gecko/20030728 Mozilla Firebird/0.6.1

Normally, clicking on an image submit button sends a name.x and name.y variable.
 When the image is not there, however, FireBird displays the ALT text for the
image.  However, when you click on that alt text, the form is submitted, but the
name.x and name.y variable are not sent.  This causes PHP code that does this to
fail:

if (isset($name_x)) ...

(Those name.x variables appear as $name_x) in PHP.


Reproducible: Always

Steps to Reproduce:
1.Create an image submit button with an image src that doesn't exist.  Also
supply an ALT tag.
2.Try submitting the form and see that it does not send the submit form element name
3.



Expected Results:  
It should have sent name.x=0 and name.y=0 or something.  Sending name=something
would be bad for compatibility.

Reporter, have you got a testcase/URL so that others can reproduce this problem?

The summary says that the name is not submitted, but by the description I think
you mean the co-ordinates. Suggest change summary to something like "send
dummy/default values for x,y co-ordinates when alt text replaces image for form
submit".

I suspect this should be under Browser->Form Submission (unless the action of
Firebird differs from Mozilla).

This is a duplicate.  Please find the original (in the "Browser" product), and
resolve this as duplicate of it.

I can't find the dupe. 

Moving to Browser to see if someone there knows where it is.

The dup is bug 122238. Hope this gets fixed soon.
