Question

我正在尝试创建一个压缩文件夹来存储wordpress数据库中的所有图像。我的图像是从数据库中提取的，但无法创建压缩文件。我在Stack Overflow上读到php不从http:\\创建zip然后我用绝对路径做了它，仍然没有运气:(。我试过以下代码来生成Zip

add_action("gform_after_submission_89", "export_triphub_2_zip", 10, 2);
function export_triphub_2_zip($entry, $form)
{
    global $wpdb,$current_user;
    get_currentuserinfo();
    $uid = $current_user->ID;
    $photos = array();
    $path = getcwd();
   foreach($entry as $item)
   {

        if($item != '')
        {
              if($item == 'Photos')
              {
                 $photos[] = $wpdb->get_results("select photo_path from wp_triphub_photos where userid=".$uid);
                 $photos   = $photos[0];
                 foreach($photos as $photo)
                 {
                    if($photo->photo_path != '')
                    {
                       $files[] = $path.'/dev.guestseed.com'.$photo->photo_path;
                    }
                 }
              }
              elseif($item == 'Hotel')
              {
                 $photos1[] = $wpdb->get_results("select room_photo from wp_triphub_hotel_room_info where userid=".$uid);
                 $photos1   = $photos1[0];
                 foreach($photos1 as $photo1)
                 {
                    if($photo1->room_photo != '')
                    {
                       $files[] = $path.'/dev.guestseed.com'.$photo1->room_photo;
                    }
                 }
              }
              elseif($item == 'Activity')
              {
                 $photos2[] = $wpdb->get_results("select activity_photo from wp_triphub_activity_info where userid=".$uid);
                 $photos2   = $photos2[0];
                 foreach($photos2 as $photo2)
                 {
                    if($photo2->activity_photo != '')
                    {
                       $files[] = $path.'/dev.guestseed.com'.$photo2->activity_photo;
                    }
                 }
              }
              elseif($item == 'People')
              {
                 $photos3[] = $wpdb->get_results("select person_pic from wp_triphub_people_photos where userid=".$uid);
                 $photos3   = $photos3[0];
                 foreach($photos3 as $photo3)
                 {
                    if($photo3->person_pic != '')
                    {
                       $files[] = $path.'/dev.guestseed.com'.$photo3->person_pic;
                    }
                 }
              }
        }

    }

    echo "<pre>";
      print_r($files); //Files are being fetched properly
    echo "</pre>";

    $zipname = 'file.zip';
    $zip = new ZipArchive;
    $zip->open($zipname, ZipArchive::CREATE);
    foreach ($files as $file) {
        $zip->addFile($file);
    }
    $zip->close();


}

以下是print_r结果

Answer 1

来自php.net的两条建议

1。If you're adding multiple files to a zip and your $zip->close() call is returning FALSE, ensure that all the files you added actually exist. Apparently $zip->addFile() returns TRUE even if the file doesn't actually exist. It's a good idea to check each file with file_exists() or is_readable() before calling $zip->addFile() on it.

2。Don't forget to check the zip isn't empty, folks - otherwise the zip won't be created at all, and the server will issue no warning!

Answer 2

首先，根据下面的对话，在使用此代码将图像下载到压缩文件夹后，将PATH更改为使用http：//。

$zip = new ZipArchive(); 
$tmp_file = tempnam('.',''); 
$zip->open($tmp_file, ZipArchive::CREATE); 
    foreach($files as $file){ 
        $download_file = file_get_contents($file); 
    $zip->addFromString(basename($file),$download_file); 
    $zip->close(); 
header('Content-disposition: attachment; filename=download.zip'); 
header('Content-type: application/zip'); 
readfile($tmp_file);

希望有所帮助，

PHP没有创建Zip
