PHP problem

[DragonEye]

Hi,

I am a complete newbie when it comes to PHP.

I have installed Apache PHP and MySQL on my home computer for testing purposes and I have bought myself a PHP book.

But when I try out the first example in the book things already start going wrong, here is my problem.

If I write this form in HTML:
<FORM ACTION="process.php" METHOD="post">
<B>Name</B><INPUT TYPE="text" NAME="name">
<BR><INPUT TYPE="submit" VALUE="Sign">
</FORM>

My book says that if I would create such a form and send it to a php script that I would have a variable $submit that equals "Sign!" if I try this out PHP gives me an error message that $submit is not defined.

Is there anyone who has an explanation for this?

Well, I'm not sure about this.. but..

I do this with submit buttons:

<input type=submit name=submit value=Sign>

Therefore, because the input is named submit, $submit would equal "Sign". It works for me.

He's right about that. The "name" attribute of the HTML tag is what becomes the name of the variable that is passed. However.......

If you're running a newer version of PHP, they got rid of gobal variables (rather, the default is now OFF). What that means is that your form no longer sends every variable individually.

Instead, it sends them as elements of an array called $_POST

Therefore, try to access the variable in your script by using $_POST['submit'];

That should equal "Sign"
