This is actually a javascript issue rather than a PHP issue. What is
happening is that the action of the form is what is being submitted.
The action never changes. What you need to do is have the javascript
change the action as well as submit the form (which means you will need
to move it to a function). It would also help to empty out the form
action as well.
Example JS function:
function retrieveAllPerm()
{
document.display_data.action='http://unproto.demog.berkeley.edu/memdemo/edit_query_form.php?perm_batch_file=perm&pg_query_form_id=518&query_form_schema=permanent_queries';
document.display_data.submit();
}
Example submit button:
<button name='edit_existing_query_form'
onClick="javascript:retrieveAllPerm();" >Revise query</button>

Hi,
I am writing code in PHP which generates HTML script. My app is
fairly complex. Twice in the development of the application I have
run into a problem with submit buttons which pick up the wrong url.
Instead of call the url for that submit button, it appears to call the
url for the first submit button on the page. The problem may be
intermittent, which seems to suggest that something funny is happening
with the cache. Clearing the cache did not help in the last go around.
I am including the generated html code. Hitting the button 'Retrieve
all ...' should call up the url get_query_forms.php. Instead it calls
up the url query_form_display_data.php, which is the url for the first
submit button on the page.
Any clues to clear up this mystery would be greatly appreciated!
