[PHP] Re: Using a HTML button
PHP is a server-side language (i.e. Perl when used with mod_perl), not a
client-side language (i.e. JavaScript). All of the processing is done on
the server BEFORE it is sent to the user. Therefore, you can't call a PHP
function directly from a web page after the user has received it, since all
of the processing has already been done.

Hi,
I am rather new to PHP so I hope somebody can help me.
I have a normal button (HTML code). Then I have made a function
function multiply($X)
{
return 2*$X;
}
The button has an OnClick, which calls my function.
INPUT TYPE=BUTTON name=HH value=Mul onClick=? $XX=multiply(5);?
I then writes $X to the screen.
?php echo $X ?
The problem is I dont even have to press the button. When the page loads
it already has calculated 2*$X. Why is that. I would like to only call my
function when I press my button.
Please help
Morten
