I am doing some basic Ajax stuff (not jquery.. just learning the basics), and I have a general structure set up where html calls a javascript function which sends data to and runs a specific php page.
But what if I just need to run a php function that's already defined in functions.php. Is that possible at all? I'm getting tired of making new php files for every task ;)
You could define a class in php to handle stuff like this, such as:
functions.php:
class MyFunctions {
function foo() {
// code here
// if you need to pass in some parameters, you can do it via jQuery and fetch the data like so (for the jQuery, see below)
if($_GET['name'] == "john") { } // do stuff
}
function bar() {
// code here
}
static function handleFn($fName) {
if(method_exists(__CLASS__, $fname)) {
echo $this->{$fname}(); die; // since AJAX, just echo the output and stop executing
}
}
}
if(!empty($_GET['f'])) {
MyFunctions::handleFn($_GET['f']);
}
Then do your ajax call like so (assuming jQuery):
$.get("/functions.php?f=func_name_to_call", {name: "John", hobby: "Programming"}, function(data) {
});
In the PHP script surround each function with a if statement designed to check a GET variable. Then in the JS send a GET variable specific to the one required to call that function.
ajax is also an http request, which cannot call php functions directly
