Re: Re: Best way to test for form submission?

I've encountered issue with checking $_POST['submit'] if(isset($_POST['submit'])) {} If the form consists of checkbox/radio and text field, some of my forms can be submitted by just press [ENTER] at the end of one of the text field. In this case, the $_POST['submit'] is set even the submit button was not clicked. However, in some of my forms, $_POST['submit'] will not be set if I submit the form by pressing [ENTER] in one of the text field. So, if the later case happen, I need to remind the user to explicitly click the [Submit] button. I don't know why or in what condition that pressing [ENTER] will not submit the whole form include the $_POST['submit'].

This question might give away the fact that I am a php noob, but I am looking for the best way to test for form submission in PHP. I know in Perl this can be done with if (param) but I don't know if that will work with PHP. I have read the Learning PHP 5 book and the only thing that was mentioned in the book was the use of something like this print "<p>Hello ".$_POST['username']."</p>";

Sorry copied and pasted the wrong line (long day) if (array_key_exists('username',$_POST))

I'm sure that this is not the best/recommended way to do this but I'm hoping someone here will point me in the right direction.

The best way I've found is to do something like this: if(isset($_POST['submit'])) {} Note that in-place of submit you can put the name of any form element. I chose submit here, because every form should have a submit button. Note also that this will only work if you have given your submit button a name: <input type="submit" name="submit" value="Submit"/> Thanks, Ash http://www.ashleysheridan.co.uk
