html push button and php code

[calmchess]

I'm trying to use the following html code to execute a php function that simply echo's a message to the user the php function seems to get executed but the echo never shows up on the screen and i get a IE error box that says checking undefined. what am i doing wrong?

 

<input type="button" name="chAvail" onClick="<?chAvail()?>" value="Submit"></td></tr>

<?function chAvail (){echo "checking";}?>

taking a stab at this, but can't onClick only launch a javascript function, not a php function ?

You are trying to use a javascript function as a php function.

 

 

Do you know what PHP stands for?

yeah, PHP (server side) and HTML/JavaScript (client side) are two different worlds. the easiest way to understand what JavaScript is doing is to load up the page in the browser and do a View Source. What you see there is the client side code that is getting run.
