wierd form behavior

[Anon]

hi,
i have already come up with an alternate solution to this problem, i thought it was strange though and wanted to see if anyone can explain this:

i have a form with a submit button:
name=submit value=submit type=submit

the form action is $PHP_SELF, when it loads it looks for the variable $submit and if it is there, the code is executed. for some reason if the enter key is pressed, the submit button seems to be bypassed and my code does not run. if the button is clicked, everything works as expected.

i resolved this by adding a hidden field:
name=fsubmit value=fsubmit type=hidden

now i check for $fsubmit and it works fine both ways. any explanation for this?

thanks!

The form has to go through the submit button.
You probably don't test for it properly.

Try:
if ($submit != "")
or:
if ($submit)
or:
if (!empty($submit))
or
if (!isset($submit))

Hi Paul

I don't have an explanation but your post just solved a problem I had with a new site.

Thanks for posting that!

wow, that was an old post!

it is wierd though. the reason that happens is because a single field form can be submitted without even having a submit button on the page (by hitting enter). if you do have a submit button and you hit enter it submits without using the submit button, so its value isnt passed.

this same wierdness happens with any form that has only one text box, but it can have any number of other elements.
