PrestaShop:允许客户上传PDF、AI和EPS文件作为产品定制

Question

我正在运行Prestashop 1.6.1.7，我有以下pictureUpload()方法，允许用户上传自己选择的文件。默认情况下，Prestashop只允许上传GIF、JPG、JPEG或PNG。

我试图允许用户上传更多的类型(pdf，ai和eps )。

下面是pictureUpload()方法在productController覆盖中的应用：

protected function pictureUpload()
{
    if (!$field_ids = $this->product->getCustomizationFieldIds()) {
        return false;
    }
    $authorized_file_fields = array();
    foreach ($field_ids as $field_id) {
        if ($field_id['type'] == Product::CUSTOMIZE_FILE) {
            $authorized_file_fields[(int)$field_id['id_customization_field']] = 'file'.(int)$field_id['id_customization_field'];
        }
    }
    $indexes = array_flip($authorized_file_fields);
    foreach ($_FILES as $field_name => $file) {
        if (in_array($field_name, $authorized_file_fields) && isset($file['tmp_name']) && !empty($file['tmp_name'])) {
            //$file_name = md5(uniqid(rand(), true));
            $file_name = $file['name']; // In this

            if ($error = ImageManager::validateUpload($file, (int)Configuration::get('PS_PRODUCT_PICTURE_MAX_SIZE'))) {
                $this->errors[] = $error;
            }

            $product_picture_width = (int)Configuration::get('PS_PRODUCT_PICTURE_WIDTH');
            $product_picture_height = (int)Configuration::get('PS_PRODUCT_PICTURE_HEIGHT');
            $tmp_name = tempnam(_PS_TMP_IMG_DIR_, 'PS');
            if ($error || (!$tmp_name || !move_uploaded_file($file['tmp_name'], $tmp_name))) {
                return false;
            }
            /* Original file */
            if (!ImageManager::resize($tmp_name, _PS_UPLOAD_DIR_.$file_name)) {
                $this->errors[] = Tools::displayError('An error occurred during the image upload process.');
            }
            /* A smaller one */
            elseif (!ImageManager::resize($tmp_name, _PS_UPLOAD_DIR_.$file_name.'_small', $product_picture_width, $product_picture_height)) {
                $this->errors[] = Tools::displayError('An error occurred during the image upload process.');
            } elseif (!chmod(_PS_UPLOAD_DIR_.$file_name, 0777) || !chmod(_PS_UPLOAD_DIR_.$file_name.'_small', 0777)) {
                $this->errors[] = Tools::displayError('An error occurred during the image upload process.');
            } else {
                $this->context->cart->addPictureToProduct($this->product->id, $indexes[$field_name], Product::CUSTOMIZE_FILE, $file_name);
            }
            unlink($tmp_name);
        }
    }
    return true;
}

这里查看的是ImageManager类，它具有以下方法(我已经更新了错误消息)：

public static function validateUpload($file, $max_file_size = 0, $types = null)
{

    if ((int)$max_file_size > 0 && $file['size'] > (int)$max_file_size) {
        return sprintf(Tools::displayError('Image is too large (%1$d kB). Maximum allowed: %2$d kB'), $file['size'] / 1024, $max_file_size / 1024);
    }
    if (!ImageManager::isRealImage($file['tmp_name'], $file['type']) || !ImageManager::isCorrectImageFileExt($file['name'], $types) || preg_match('/\%00/', $file['name'])) {
        return Tools::displayError('Image format not recognized, allowed formats are: .gif, .jpg, .png, .pdf, .ai, .eps'); //I Updated This - this is the error kicking off when I try to upload AI
    }
    if ($file['error']) {
        return sprintf(Tools::displayError('Error while uploading image; please change your server\'s settings. (Error code: %s)'), $file['error']);
    }
    return false;
}

该方法失败的地方是指向下面发布的另外两个方法。我更新了isRealImage方法以尝试并允许我想要通过的类型，但是它仍然失败(并且我评论了它失败的地方)。

public static function isRealImage($filename, $file_mime_type = null, $mime_type_list = null)
{
    // Detect mime content type
    $mime_type = false;
    if (!$mime_type_list) {
        //I UPDATED THIS LIST TO ALLOW FOR OTHER FILETYPES
        $mime_type_list = array('image/gif', 'image/jpg', 'image/jpeg', 'image/pjpeg', 'image/png', 'image/x-png', 'application/illustrator', 'application/ai', 'application/eps', 'application/x-eps', 'image/eps', 'image/x-eps', 'application/pdf', 'application/acrobat', 'application/x-pdf', 'text/pdf', 'text/x-pdf');
    }

    // Try 4 different methods to determine the mime type

    if (function_exists('getimagesize')) {
        $image_info = @getimagesize($filename);
        //HERE IMAGE_INFO IS SHOWING AS 'FALSE' SO IT GOES NO FURTHER WHEN UPLOADING A .AI FILE
        if ($image_info) {
            $mime_type = $image_info['mime'];
        } else {
            $file_mime_type = false;
        }
    } elseif (function_exists('finfo_open')) {
        $const = defined('FILEINFO_MIME_TYPE') ? FILEINFO_MIME_TYPE : FILEINFO_MIME;
        $finfo = finfo_open($const);
        $mime_type = finfo_file($finfo, $filename);
        finfo_close($finfo);
    } elseif (function_exists('mime_content_type')) {
        $mime_type = mime_content_type($filename);
    } elseif (function_exists('exec')) {
        $mime_type = trim(exec('file -b --mime-type '.escapeshellarg($filename)));
        if (!$mime_type) {
            $mime_type = trim(exec('file --mime '.escapeshellarg($filename)));
        }
        if (!$mime_type) {
            $mime_type = trim(exec('file -bi '.escapeshellarg($filename)));
        }
    }

    if ($file_mime_type && (empty($mime_type) || $mime_type == 'regular file' || $mime_type == 'text/plain')) {
        $mime_type = $file_mime_type;
    }

    // For each allowed MIME type, we are looking for it inside the current MIME type
    foreach ($mime_type_list as $type) {
        if (strstr($mime_type, $type)) {
            return true;
        }
    }

    return false;
}

我还更新了isCorrectImageFileExt方法：

public static function isCorrectImageFileExt($filename, $authorized_extensions = null)
{
    // Filter on file extension
    if ($authorized_extensions === null) {
        //ADDED ALLOWED TYPES I WANT
        $authorized_extensions = array('gif', 'jpg', 'jpeg', 'jpe', 'png', 'pdf', 'ai', 'eps');
    }
    $name_explode = explode('.', $filename);
    if (count($name_explode) >= 2) {
        $current_extension = strtolower($name_explode[count($name_explode) - 1]);
        if (!in_array($current_extension, $authorized_extensions)) {
            return false;
        }
    } else {
        return false;
    }

    return true;
}

对此有什么想法吗？

帮个忙？

你走得太深了:)。这是我已经做过的pictureUpload ProductController方法，您不需要其他重写。有了我的覆盖，你可以上传pdf，ai，cdr和eps，但很明显，你可以改变你的需要。

protected function pictureUpload()
{
    if (!$field_ids = $this->product->getCustomizationFieldIds()) {
        return false;
    }
    $authorized_file_fields = array();
    foreach ($field_ids as $field_id) {
        if ($field_id['type'] == Product::CUSTOMIZE_FILE) {
            $authorized_file_fields[(int)$field_id['id_customization_field']] = 'file'.(int)$field_id['id_customization_field'];
        }
    }
    $indexes = array_flip($authorized_file_fields);

    foreach ($_FILES as $field_name => $file) {
        if (in_array($field_name, $authorized_file_fields) && isset($file['tmp_name']) && !empty($file['tmp_name'])) {
            $file_name = md5(uniqid(rand(), true));

            // Bad check, but rapid
            $extension = substr($file['name'], -3, 3);
            if($extension == 'jpg' OR $extension == 'gif' OR $extension == 'png'){
                if ($error = ImageManager::validateUpload($file, (int)Configuration::get('PS_PRODUCT_PICTURE_MAX_SIZE'))) {
                    $this->errors[] = $error;
                }

                $product_picture_width = (int)Configuration::get('PS_PRODUCT_PICTURE_WIDTH');
                $product_picture_height = (int)Configuration::get('PS_PRODUCT_PICTURE_HEIGHT');
                $tmp_name = tempnam(_PS_TMP_IMG_DIR_, 'PS');
                if ($error || (!$tmp_name || !move_uploaded_file($file['tmp_name'], $tmp_name))) {
                    return false;
                }
                /* Original file */
                if (!ImageManager::resize($tmp_name, _PS_UPLOAD_DIR_.$file_name)) {
                    $this->errors[] = Tools::displayError('An error occurred during the image upload process.');
                }
                /* A smaller one */
                elseif (!ImageManager::resize($tmp_name, _PS_UPLOAD_DIR_.$file_name.'_small', $product_picture_width, $product_picture_height)) {
                    $this->errors[] = Tools::displayError('An error occurred during the image upload process.');
                } elseif (!chmod(_PS_UPLOAD_DIR_.$file_name, 0777) || !chmod(_PS_UPLOAD_DIR_.$file_name.'_small', 0777)) {
                    $this->errors[] = Tools::displayError('An error occurred during the image upload process.');
                } else {
                    $this->context->cart->addPictureToProduct($this->product->id, $indexes[$field_name], Product::CUSTOMIZE_FILE, $file_name);
                }
                unlink($tmp_name);
            } elseif ($extension == 'pdf' OR $extension == '.ai' OR $extension == 'cdr' OR $extension == 'eps') {
                $file_name = $file_name.'.'.str_replace('.', '', $extension);
                if (!move_uploaded_file($file['tmp_name'], _PS_UPLOAD_DIR_.$file_name)) {
                    return false;
                }
                chmod(_PS_UPLOAD_DIR_.$file_name, 0777);
                $this->context->cart->addPictureToProduct($this->product->id, $indexes[$field_name], Product::CUSTOMIZE_FILE, $file_name);
            } else {
                $this->errors[] = Tools::displayError('This format is not accepted');
            }
        }
    }
    return true;
}

之后，您必须自定义product.tpl、模板的购物车摘要和后台订单详细信息:)

如果您不想黑入您的PrestaShop安装(如果您想要安全地升级PretaShop，则不建议这样做)，另一种解决方案是开发或使用现有模块。

PrestaShop市场上的这个模块可能就是您要寻找的内容：https://addons.prestashop.com/en/front-office-features-prestashop-modules/88383-upload-any-file-type-in-product-customization.html
