Button to execute

[lljr]

I cant seem to find a code to execute a PHP section when a button is pressed, can anybody supply this or have a link? thanks in advance!

What do you mean? Like a submit button?

[lljr]

no, i want to use the random coding to insert a random number but only when a button is pushed, but i dont know how to do the button part...

A button is clientside, PHP is a serverside language. You'd need to use a form like this..

 

<form action="whatever.php" method="post">

<input type="button" value="click me to calculate!"/>

</form

 

And it'll POST and inputs etc. to whatever.php. If you use a text input for example like you'd see in normal forms.. if an input was named 'name="ID" ' you could see it in PHP as.. $_POST['ID']..

 

Edit: You may want to use JS to insert a random number into the box. You can do buttons like this..

 

<button onClick="document.getelementbyID('rand1').value = 4">Button</button>

You mean like <input type="image" name="submit" > ???

 

When an image is clicked it sends the XY coordinates of the screen position that the mouse clicked.

 

To execute code with an image input you have to use

if ( isSet($_POST['submit_x']) )
{
   //code
}
//or 
if ( isSet($_POST['submit_y']) )
{
   //code
}
