writing a PHP command as a string

[bradoirs]

I want to call a PHP function based on information extracted from a form with javascript

hard-coded works fine:

if (x=="BSP"){
if (b){
var thecontent="<?php distincttype('BSP') ?>";
document.getElementById("BSP").innerHTML =thecontent;
}else{
document.getElementById("BSP").innerHTML ="";
}
}

What I am looking to do is change the php element depending on the content of a form element to replace the 'BSP' with the variable y
var y=document.forms["FindForm"]["myRef"].value; (assume value is "XYZ")

by creating a string variable thecontent
var thecontent="<?php distincttype('"+y+"') >?";

I can create the variable but it just doesnt work when the routine is substituted for the hard code.

Javascript remains a mystery to me so any help welcome and plkease be gentle with me

PHP runs BEFORE the javascript is even delivered to the browser, so you will have to use AJAX to call the PHP function.

You can't. PHP and Javascript cannot directly interact. PHP is executed on the server. By the time JS runs, whatever PHP you have has already run, and delivered whatever it produced to the browser.

If you need to execute a PHP function based on a JS value, you'll need to look into Ajax.
