Hi, If a web page has JavaScript called on a submit button, like 'onClick="someFunction();", and the function does some stuff, then does a form.submit(), and DOES NOT REMEMBER TO RETURN FALSE, then the browser is supposed to go ahead and submit the form. So, something like that could possibly happen, but only if the JavaScript is incorrectly written, as far as I know. Although, once a submit is done, it would be a gray area as to whether the form data would still be available for the second submit.
I think this thread discuss the problem .. like they say I started having the problem with some version of IE6 but not IE5.

They don't give the answer but when they talk
here is what it might be:
<input class="input" type="submit " name="Submit" value="Submit" onClick="javascript:submitit();">
if you use javascript to submit the form
do not use a button type of submit.........it will submit twice
correct code
<input class="input" type="button " name="Submit" value="Submit" onClick="javascript:submitit();">
<input class="input" type="submit " name="Submit" value="Submit" onClick="javascript:submitit();">
if you use javascript to submit the form
do not use a button type of submit.........it will submit twice
correct code
<input class="input" type="button " name="Submit" value="Submit" onClick="javascript:submitit();">
Like SCassidy said .. maybe returing FALSE will solve the problem .. but I remember having tried this without success...
It's all what I know :-)
I use JavaScript in forms all the time to interact with a PostgreSQL database, and don't have any issues like this with debugged code, using IE6.

Per example, if you have a submit button and call a javascript that actually post the form... IE will still do the post attached to the submit button. So you will have 2 submits.... It's stupid but it's true. It's happen on some version of IE6 I think .. not all for what I remember. You can search the web for the solution ... I don't remember what I did or if I actually did something to solve the problem. /David P.S.: This is quite OT for the postgresql mailing list .. you don't think ?

When the browser is Firefox , it works perfect; when the browser is IE, it dumps 2 entries into the table just thousandths of a second apart. What could be causing this? Is this an issue with IE, Apache or Postgres.
