Adding the new hook to prestashop and attaching it to admin page

[NatasaN]

Hi,

I'm trying to create a module for admin panel -> Store Contacts.

The idea is to add just one input csv file field.

 

I created a hook ActionAdminStoresControllersCsvUpload , and connected it with Store Contacts page by overriding this controller: AdminStoresController adding only this function:

 

 public function initContent() {

            parent::initContent();

            Hook::exec('actionAdminStoresControllersCsvUpload');

        }

 

The next step is creating a module: uploadStoresViaCsv. The Problem Starts Here. For the beginning I want to display only text at Store Contacts page.

 

In the module php file i added this function:

 

 public function hookActionAdminStoresControllersCsvUpload() {

          

            $helpme="Test if we are connected";

            

           $this->smarty->assign('helpme', $helpme);

         

 

return $this->display(__FILE__, 'upload_stores.tpl');

            

        }

 

and create in root tpl file with this code

 

<div class="col-lg-4">

            

            {$helpme}

</div>

 

and NOTHING is happening. I don't know why. Wen i do var_dump of $helpme in php I see the content. But when I send the value regularly, i get nothing.

 

I think that the problem is in new hook. 

 

What do you think?

if you put die(); to the  public function hookActionAdminStoresControllersCsvUpload() function

does this die() freeze the page? (white page)

[NatasaN]

Yes... If i put die() or exit() the page is blank.

[vekia]

so it properly executing the hook and code inside

action hooks aren't visible, you can "run" some code there only, like die() funciton ;-)

I change that. I created the hook hookDisplayCsvUpload. 

If I add this in function hookDisplayCsvUpload

 

             public function hookDisplayCsvUpload($params) {

         

                   $this->smarty->assign('helper', "test me");

                   var_dump($this->display(__FILE__, 'views/upload_csv_form_admin.tpl'));

                   exit();

                  return $this->display(__FILE__, 'views/upload_csv_form_admin.tpl');

            

              }

 

The result will be the form from tpl. file :

string '<div class="form-group">
    <label class="control-label col-lg-3">
        <span class="label-tooltip" data-toggle="tooltip" data-html="true" title="" data-original-title="You can upload a maximum of 3 images.">
            Thumbnails
        </span>
    </label>
    <div class="col-lg-4">
        test me
    </div>
</div>
' (length=287)

 

BUT the MAIN problem is that I dont see that content om my admin page Store Contacts.

Any idea?
