¿Qué hace esto en imgcheck.php?

[Bany]

Hola,

buscando alguna forma de eliminar las imágenes de productos eliminados, encontré que alguien ofrecía este archivo:

 

 

<?php

// include(dirname(__FILE__).'/../config/config.inc.php');

if (!defined('_PS_VERSION_'))

    exit;

 

class ImgCheck extends Module {

    public function __construct()

    {

        $this->name = 'imgcheck';

        $this->tab = 'others';

        $this->version = '1.0';

        $this->author = 'Rob O\'Donnell';

        $this->need_instance = 0;

//        $this->ps_versions_compliancy = array('min' => '1.5', 'max' => '1.5');

        $this->dependencies = array('blockcart');

 

        parent::__construct();

 

        $this->displayName = $this->l('Image Check');

        $this->description = $this->l('Helps Rob delete thumbnail sized first images.');

 

        $this->confirmUninstall = $this->l('Are you sure you want to uninstall?');

        // if (!Configuration::get('MYMODULE_NAME'))

        // $this->warning = $this->l('No name provided');

    }

 

// this also works, and is more future-proof

public function install()

{

if (parent::install() == false)

return false;

return true;

}

 

public function uninstall()

{

if (!parent::uninstall() ||

!Configuration::deleteByName('MYMODULE_NAME'))

return false;

return true;

}

    public function getContent()

    {

        $go = Tools::getValue('go');

 

        $sql = 'SELECT i.`id_image` as id1, i2.`id_image` as id2, p.`id_product` as id_product

FROM `ps_image` i ' .

Shop::addSqlAssociation('image', 'i').'

LEFT JOIN `ps_image` i2 on i2.id_image = i.id_image + 1

left outer join ps_product p on p.id_product = i.id_product

WHERE i.id_product = i2.id_product AND i.cover = 1 AND i.position = 1 AND p.id_shop_default = 1 ';

 

        $results = Db::getInstance()->ExecuteS($sql);

 

        $form = '';

 

        if (empty($go)) {

            $form .= '<form method="POST" action="#">';

            $form .= '<input type="hidden" name="go" value="go">';

            $form .= '<table>';

            foreach ($results as $key => $row) {

                $form .= '<tr>';

                $form .= '<td>' . $row['id_product'] . '</td>';

 

                $image1 = new Image($row['id1']);

                $image2 = new Image($row['id2']);

                $image1link = self::_getPictureLink($row['id_product'], $row['id1'], null, 'large');

                $image2link = self::_getPictureLink($row['id_product'], $row['id2'], null, 'large');

 

                $form .= '<td><img src="' . $image1link . '" width="150"><br>' . '</td>';

                $form .= '<td><img src="' . $image2link . '" width="150"><br>' . '</td>';

 

                $form .= '<td><input type="checkbox" name="im' . $row['id1'] . '" checked>';

                $form .= '<input type="hidden" name="pr' . $row['id1'] . '" value="' . $row['id_product'] . '">';

                $form .= '</td>';

 

                $form .= '</tr>';

            }

            $form .= '</table>';

            $form .= '<input type="submit">';

        } else {

            foreach ($results as $key => $row) {

                if (Tools::getValue('im' . $row['id1'])) {

                    $form .= "<br/>Deleting image " . $row['id1'] . ' for product ' . $row['id_product'] ;

 

                    $image = new Image($row['id1']);

                    $image->delete();

 

                $image2 = new Image($row['id2']);

                $image2->cover = 1;

                if (!$image2->update())

 

                $form .= ' - FAILED';

                }

            }

        }

 

        return $form;

    }

 

    private function _getPictureLink($id_product, $id_image, $context_link, $size, $id_shop = null)

    {

        // Fix for payment modules validating orders out of context, $link will not  generate fatal error.

        $link = is_object($context_link) ? $context_link : new Link();

        $prefix = (substr(_PS_VERSION_, 0, 3) == '1.3' ? Tools::getShopDomain(true, false, $id_shop) . '/' : '');

 

    }

}

 

?>

 

 

Perdonad mi ignorancia, pero, ¿eso sirve realmente para eliminar las imágenes de los productos ya eliminados?

 

 

Un saludo
