PHP Function Automatically

[Angel Moral]

I created a prestashop page with php, I use a page controller and the page.tpl, the problem is that I have a button that calls a function of the controller but this does not happen, but the function is called automatically when refresh the page.

it is only logical it happens this way, I suggest you remove the call from the tpl page and call your function form JS file using AJAX.

How can i do that?

I have do this:

And show me this error, I have looked in forums and the syntax is correct.

$this -> context -> controller -> addJS($this -> _path . '/views/js/front.js');

add the JS code into the module's front.js which in turn has to be loaded by the module using the PS built in functions.

You need to study the PS or other modules code to understand how it supposed to work.

i dont know where is module's front.js. I have not create a module, i created a controller in controllers/front/NadieController.php and i would link to call it in nadie.tpl. I resolve the error in syntax. Now my files look like this:

nadie.tpl (themes/classic/templates)

{extends file='page.tpl'}
{block name='page_title'}
<span class="sitemap-title">{l s='Plantilla descargable' d='Shop.Theme'}</span>
{/block}
{block name='page_content_container'}
<section>
<p><label>Introduce ancho:</label> <input type="text" id="name" name="name" maxlength="8" size="10" /></p>
<p><label>Introduce alto:</label> <input type="text" id="name" name="name" maxlength="8" size="10" /></p>
<button onclick="myFunction()">Click me</button>

<p id="demo"></p>
</section>

{literal}
<script>
function myFunction() {
  document.getElementById("demo");
  console.log("Entro myfuncion");
  $.ajax(
            {
                type: 'POST',
                data: {action:'getPDF'},
                url: here i need to call NadieController,
                
                success: function (response) {
                    console.log(response);
                }
            }
    );
}
</script>
{/literal}
{/block}

 

NadieController.php

<?php
class NadieControllerCore extends FrontController
{

public $php_self = 'nadie';

public function initContent()
{
parent::initContent();
if(isset($_POST['action']) && !empty($_POST['action'])) {
    echo "<script>console.log( 'Entro IF' );</script>";
    $action = $_POST['action'];
    switch($action) {
        case 'getPDF' : getPDF();break;
        // ...etc...
    }
}

$this->setTemplate('nadie');

}


public static function getPDF(){
ob_start();
require('vendor/fpdf/fpdf.php');
$pdf = new FPDF('P','mm',array(20,10));
$pdf->AddPage();
$pdf->Output();
}
