jquery Ajax url point to php functions - php

Question

hi is it possible to retrieve data from a PHP function using Ajax?.
i want my url in ajax to point in one of my functions. please see my code below.
like this:
<?php
class employee{
public function __construct(){
}
public function fName($fName){
echo $fName;
}
public function lName($lName){
echo $lName;
}
}
?>
<div id="fName"></div>
<script type="text/javascript">
$.ajax({
type: 'POST',
url: "classes.php", <!-- HERE I want to target the fname function-->
success: function(result){
fname.html(result);}
});
</script>
what im doing so far is create a new php page which contain code like this.
<?php
$employee = new employee();
$employee->fName();
then ill point the ajax url to that new php page.

Answer 1

Assuming this code works as written in your question
<?php
$employee = new employee();
$employee->fName();
you can pass a parameter to your PHP script then decided which function is to be called like so:
jQuery:
$.ajax({
type: 'GET',
url: "classes.php?func=fname",
success: function(result) {
$("fname").html(result);
}
});
PHP - classes.php:
<?php
$employee = new employee();
$func = #$_GET["func"];
switch($func) {
case "fname":
echo $employee->fName();
break;
case "lname":
echo $employee->lName();
break;
default:
break;
}

The url property has to be a url .. in your case it perhaps will point to "/classes.php" , assuming the file is on document root of the webserver
The function fName needs to be called by the code present in that url.
so your file "/classes.php" should look like this
<?php
class Employee {
protected fName;
protected lName;
function __construct($f, $l) {
$this->fName = $f;
$this->lName = $l;
}
public function getFName(){
return $this->fName ;
}
public function getLName(){
return $this->lName ;
}
}
$employee = new Employee("John" , "Doe");
echo $employee ->fName();
