我正在运行Prestashop 1.6.1.7并且我有以下pictureUpload（）方法，允许用户上传他们选择的文件。默认情况下，Prestashop仅允许上传GIF，JPG，JPEG或PNG。
我试图让用户能够上传更多类型（特别是pdf，ai和eps）
这是productController覆盖中的pictureUpload（）方法：
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;
}
这是寻找ImageManager类，它有这个方法（我已经更新了错误信息）：
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)'), $file['error']);
}
return false;
}
该方法失败的地方指向下面发布的另外两种方法。我更新了isRealImage方法以尝试允许我想要的类型，但它仍然失败（我评论它失败的地方）。
public static function isRealImage($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;
}
对此的想法？
帮助吗？

你太深了:)这是我已经制作的pictureUpload ProductController方法，您不需要其他覆盖。使用我的覆盖，您可以上传pdf，ai，cdr和eps，但显然您可以根据需要进行更改。
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，模板的购物车摘要以及后台订单明细：）
