Ajax call on same controller while using front controller

Ajax call on same controller while using front controller to perform some custom action using jquery ajax in prestashop.

We have seen many times in admin controller when they call ajax request to perform some action, they refer the same admin controller in ajax url instead of different controller, so that they don’t need to create any other controller to get response and perform any custom action on that.

Below is the example code where they have used same admin controller to get the response from the call which triggered to get or perform some action.

Example of admin controller –

Jquery Ajax Call

$.ajax({
	url : yourAdminController.php
	type : 'POST',
	cache : false,
	data : {
		ajax : true,
		variable_1 : var1,
		variable_2 : var2,
		action : doSomeAction,
	},
	success : function (result) {
		// your action code on result
	}
});

Admin Controller Code

class YourAdminControllerController extends ModuleAdminController
{
    public function __construct()
    {
        $this->identifier = 'id';
        parent::__construct();
        $this->bootstrap = true;
        // your own code
    }

    // your own functions
    // your own functions
    // your own functions
    // your own functions


    This function will get ajax call where pass two variables and a method name doSomeAction    
    public function ajaxProcessDoSomeAction()
    {
    	var1 = Tools::getValue('variable_1');
    	var2 = Tools::getValue('variable_2');

    	// your action code ....
    }
    
}

In Prestashop, we can follow this processor same in our front controller as well.

Here, only different is displayAjax and ajaxProcess.

• In Admin Controller – we need to prefix “ajaxProcesss” with our action function which we have passed in our ajax call , while getting ajax call.
• In front controller – we need to prefix “displayAjax” with our action function which we have passed in our ajax call, while getting ajax call.

See the example code for front controller

jQuery Ajax Call

$.ajax({
	url : yourFrontController.php
	type : 'POST',
	cache : false,
	data : {
		ajax : true,
		variable_1 : var1,
		variable_2 : var2,
		action : doSomeAction,
	},
	success : function (result) {
		// your action code on result
	}
});

Front Controller Code –

<?php

class ModuleNameYourFrontControllerFrontController extends ModuleFrontController
{
    public function initContent()
    {
    	parent::initContent();
    	// your own code
    }

    // your own functions
    // your own functions
    // your own functions
    // your own functions


    This function will get ajax call where pass two variables and a method name doSomeAction    
    public function displayAjaxDoSomeAction()
    {
    	var1 = Tools::getValue('variable_1');
    	var2 = Tools::getValue('variable_2');

    	// your action code ....
    }
    
}

In this way, we can get ajax call on our same controller either on admin side or front side. It will save your extra controller code as well as make your code more readable for each developer.

If there are something not understandable by this post then do comment below. We will surely assist on that.
