Prestashop Ajax Value to Module Class - ajax

Question

I already passed the ajax value to the front controller from js in prestashop 1.7.6.
So I first set the link in hookFooter function of module class file with
// Create a link with the path
$link = new Link;
$parameters = array("action" => "send_changed_price");
$ajax_link = $link->getModuleLink('mymodule','ajax', $parameters);
Second, used this url in custom.js file and made a Ajax call with
$.getJSON(
ajax_link,
{parameter1 : 1100},
function(data) {
if(typeof data.status !== "undefined") {
// Use your new datas here
console.log(data);
}
}
);
And get the Ajax value in init_content function of front controller mymoduele/controllers/front/ajax.php with
switch (Tools::getValue('action')) {
case 'send_changed_price':
$var1 = Tools::getValue('parameter1');
// $var1.=$var;//(float)$var1;
// Edit default response and do some work here
$response = array('status' => true, "message" => $var1);
break;
default:
break;
}
The problem is I want to use this ajax value in my module class, but not in front controller class. Because I have to use this value in hookActionCartSave(one of hook) function of my module class.
How can I pass this value to the module main class?
Or is there any other way to pass Ajax value to main module class directly?

Answer 1

From your FrontController you can call any module function you need by using $this->module->HERE_IS_NAME_OF_YOUR_MODULE_FUNCTION()

Answer 2

First, I added these data to datable with one front controller which adapt with database:
<?php
class DbAdapter extends ObjectModel {
public static $definition_array = array(
'table' => 'tablename',
'primary' => 'id',
'fields' => array(
'value1' => array('type' => self::TYPE_INT, 'validate' => 'isUnsignedId', 'required' => true),
'value2' => array('type' => self::TYPE_FLOAT, 'validate' => 'isNegativePrice', 'required' => true)
)
);
public static function insertData($value1, $value2, ...) {
$result=Db::getInstance()->insert('tablename', array(
'value1' => $value1,
'value2' => $value2,
...........
));
}
public static function getData($value1) {
$query = "SELECT * FROM `"._DB_PREFIX_."tablename` WHERE `value1` = $value1 ORDER BY id DESC";
return Db::getInstance(_PS_USE_SQL_SLAVE_)->getRow($query);
}
}
In front controller, after get the Ajax value, save them with that datatable adapter function.
switch (Tools::getValue('action')) {
case 'send_changed_price':
$var1 = Tools::getValue('parameter1');
$var2 = "additional_value";
DbAdapter::insertData($var1, $var2);
break;
default:
break;
}
And in the module main class just used getData() function
$stitch_data_row= DbAdapter::getStitch($specific_price->id_cart);
Of course, you have to include this Db adapter class php file at the top in module main class and Ajax class file.
include_once(_PS_MODULE_DIR_ . 'modulename/classes/DbAdapter.php');
