[Resolved] HTML Form Help

Is there a difference between hitting the "Enter" key on a form and simply clicking the "Submit" button?

Right now whenever I click the button on my form, my variables process as expected and everything goes according to plan. However, when I hit the enter key, the page changes, sans variables (without passing the variables, pardon my French ;p).

Thanks for any help on this horribly stupid HTML question. I can post my code if necessary.

I had the same problem and I was told that on some browsers, if you just click enter, the browser does not set a value to the submit button. So if you code is like if ($_POST["submit_button"]=="Submit") {...} then it will not get executed if your submit button's name was "submit_button" and it's value was "Submit".

This was my answered question

I'm just testing for $_POST['submit'] (an existence check, not a value check). But it doesn't even register it's existance.

$_POST['submit'] will not exist if it has no value. What I am saying is that if you press enter:
$field_name="field a"
$field_name="field b"

submit will not get a value but, if you press the submit button, the browser will set it like
$submit="submit" (or whatever the value is)
$field_name="field a"
$field_name="field b"

If you change the form method to get temporarily, you can analyze the values it sets if you then look at the address bar after submission

You were correct, because the submit button never was pressed, it was never there... which is strange, because the enter key works in the same sorts of things elsewhere, but not here... I just made it check for the $_POST vars of one of the field variables.

Thanks for all the help!
