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!
