Problem With Submit Button

[doobster]

Hello, I am having a weird problem with forms.

I am using the following form on my page:

<form action="<?=$_SERVER['PHP_SELF'];?>" method="get" name="f">
 <input type="hidden" name="guesses" value="<?=$guesses;?>">
 <input type="text" name="guess" value="<?=$hint;?>" maxlength="5">
 <input type="submit" name="submit" value="Guess">
</form>

If I am in the text field and press the enter button the submit button is not being activated because it only appends ?guesses=0&guess=xxxxx

But if I click on the submit button it further appends &submit=Guess to the above address.

Does anyone know why this is happening and more importantly how to overcome this problem.

Thanks.

submit button has it's own value, and that value will only be passed if the button is pushed. What exactly are you trying to overcome?

[doobster]

My script needs to check if(isset($_GET['submit']))

And if I push enter it is obviously not set.

Why dont you just change it over to post?

Would changing it to post affect the submit button being set if I pressed enter and did not click on the submit button?

The other thing, I am using get so I can track things through log files.
