Question

Based on my previous thread I’m trying to use ExtJS to call a function from a PHP class that lives in another area. Is this even possible or should I create a new PHP and simply pass it args? I’d prefer to use my existing code so I’m not duplicating it.

My current PHP Class handles my DB connection etc but I have no idea how or if I can instantiate the class and call a function using ExtJS.

<?php

class productInfo extends productInterface {

....

    function getProducts($code) {

        if (!$this->isConnected())
            $this->connect();

        $products = null;

        $query = "SELECT id, product FROM products Where id =  $code";

        $result = $this->dbConnection->exec_query($query);
        if ($result){
            while($row = $this->dbConnection->fetch_array($result)) {
                $products [$row['id']] = $row['product '];
            }
        }

        return $products ;
    }
}

?>

Client side code:

<select id="productFamily" onchange="getProducts()">
<option value="select">Select</option>
    ...
</select>

ExtJs

function getProducts(productFamily){

    var value = Ext.get("productFamily").dom.options[Ext.get("productFamily").dom.selectedIndex].value;

    Ext.Ajax.request({
            // How do I call getProducts(value) from ExtJS ???
    });
}

Is this possible?

drgomesp’s recommendation is definitely the easiest way to go.

However, there is a way to expose your server side API for use with ExtJS. If you really want to use your PHP functions via ExtJS, check out Ext Direct:
