[英]How can I add a button on the front end of the product page in opencart to download all product images?
我得到了這段代碼,但它不起作用。這段代碼的問題是它下載了一個空的 zip 文件......
我想下載所有產品圖片(zip 文件或不壓縮下載)
public function downloadcatalog(){
$this->load->model('catalog/product');
$product_info = $this->model_catalog_product->getProduct($this->request->get['product_id']);
$results = $this->model_catalog_product->getProductImages($this->request->get['product_id']);
foreach ($results as $result) {
$files[] = 'image/'.$result['image'];
}
$zip = new ZipArchive();
# create a temp file & open it
$tmp_file = tempnam('.', '');
$zip->open($tmp_file, ZipArchive::CREATE);
# loop through each file
foreach ($files as $file) {
# download file
$download_file = file_get_contents($file);
#add it to the zip
$zip->addFromString(basename($file), $download_file);
}
# close zip
$zip->close();
$file_name = $product_info['name'].'.zip';
# send the file to the browser as a download
/*header('Content-disposition: attachment; filename="'.$product_info['name'].'"');
header('Content-type: application/zip');*/
header("HTTP/1.1 200 OK");
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-type: application/zip");
header('Content-Disposition: attachment; filename="'.$file_name.'"');
header("Content-Transfer-Encoding: binary");
header('Content-Length: ' . filesize($tmp_file));
//$zip->close();
//readfile($zipname);
readfile($tmp_file);
unlink($tmp_file);
}
當我測試下面的代碼時,它正在下載帶有文件夾的圖像。 因此,我相信您的臨時文件夾創建然后添加到 zip 文件夾會產生問題。
public function downloadcatalog()
{
$this->load->model('catalog/product');
$product_info = $this->model_catalog_product->getProduct($this->request->get['product_id']);
$results = $this->model_catalog_product->getProductImages($this->request->get['product_id']);
foreach ($results as $result) {
$files[] = 'image/' . $result['image'];
}
$zipname = $this->request->get['product_id'] . '.zip';
$zip = new ZipArchive;
$zip->open($zipname, ZipArchive::CREATE);
foreach ($files as $file) {
$zip->addFile($file);
}
$zip->close();
header('Content-Type: application/zip');
header('Content-disposition: attachment; filename=' . $zipname);
header('Content-Length: ' . filesize($zipname));
readfile($zipname);
}
