我是一个PHP新手,正在寻找一些关于我创建的PHP函数的建议,以便在Wordpress安装中使用。
从下面的代码中可以看到,当一个管理员在一个待处理的帖子上按下'Publish'时,它会运行。
它需要一个用户通过Gravity Forms上传的Zip文件,然后解压缩。mp3扩展名。将所有文件重新压缩并移动到Amazon S3目录中的新文件夹中。
这些代码是根据我有限的知识和一些帮助拼凑在一起的。
所以,这是我最后的结果:
add_action('pending_to_publish', 'unzip_to_s3');
function unzip_to_s3() {
global $post;
global $wpdb;
// Only run function if post is portfolio post type
if ('portfolio' == $post->post_type) {
// Set temp path
$temp_path = '../wp-content/uploads/gravity_forms/1-9e5dc27086c8b2fd2e48678e1f54f98c/2013/02/tmp/';
// Get filename from Zip file
$file = get_post_meta($post->ID, 'file_url', true);
$zip_file = basename($file);
// Create full Zip file path
$zip_file_path = $temp_path.$zip_file;
// Generate unique name for temp sub_folder for unzipped files
$temp_unzip_folder = uniqid('temp_TMS_', true);
// Create full temp sub_folder path
$temp_unzip_path = $temp_path.$temp_unzip_folder;
// Make the new temp sub_folder for unzipped files
if (!mkdir($temp_unzip_path, 0755, true)) {
die('Error: Could not create path: '.$temp_unzip_path);
}
// Unzip files to temp unzip folder, ignoring anything that is not a .mp3 extension
$zip = new ZipArchive();
$filename = $zip_file_path;
if ($zip->open($filename)!==TRUE) {
exit("cannot open <$filename>n");
}
for ($i=0; $i<$zip->numFiles;$i++) {
$info = $zip->statIndex($i);
$file = pathinfo($info['name']);
if(strtolower($file['extension']) == "mp3") {
file_put_contents($temp_unzip_path.'/'.basename($info['name']), $zip->getFromIndex($i));
} else {
$zip->deleteIndex($i);
}
}
$zip->close();
// Re-zip the unzipped mp3's and store new zip file in temp folder created earlier
$temp_unzip_path = $temp_unzip_path.'/';
$zip = new ZipArchive();
$dirArray = array();
$new_zip_file = $temp_unzip_path.$zip_file;
$new = $zip->open($new_zip_file, ZIPARCHIVE::CREATE);
if ($new === true) {
$handle = opendir($temp_unzip_path);
while (false !== ($entry = readdir($handle))) {
if(!in_array($entry,array('.','..')))
{
$dirArray[] = $entry;
$zip->addFile($temp_unzip_path.$entry,$entry);
}
}
closedir($handle);
} else {
echo 'Failed to create Zip';
}
$zip->close();
// Set Media bucket dir
$bucket_path = '../wp-content/uploads/gravity_forms/1-9e5dc27086c8b2fd2e48678e1f54f98c/2013/02/mixtape2/';
// Generate unique name for sub_bucket
$sub_bucket = uniqid('TMS_', true);
// Create full sub_bucket path
$sub_bucket_path = $bucket_path.$sub_bucket;
// Make the new sub_bucket
if (!mkdir($sub_bucket_path, 0755, true)) {
die('Error: Could not create path: '.$sub_bucket_path);
}
// Move mp3's to new sub_bucket
// Get array of all source files
$files = scandir($temp_unzip_path);
// Identify directories
$source = $temp_unzip_path;
$destination = $sub_bucket_path.'/';
// Cycle through all source files
foreach ($files as $file) {
if (in_array($file, array(".",".."))) continue;
// if move files is successful delete the original temp folder
if (rename($source.$file, $destination.$file)) {
rmdir($temp_unzip_path);
}
}
// Delete original Zip file
unlink($temp_path.$zip_file);
// Update Custom field for new Zip file location
update_post_meta($post->ID, 'file_url', 'http://themixtapesite.com/wp-content/uploads/gravity_forms/1-9e5dc27086c8b2fd2e48678e1f54f98c/2013/02/mixtape2/'.$sub_bucket.'/'.$zip_file);
}
}
虽然这个函数确实有效,但我们处理的是大文件,所以它确实需要一段时间来处理…发生的事情是,当管理员按下发布,它触发了这个函数,但页面只是坐在那里,直到它完成这个函数,然后将继续。此功能最多可运行5分钟。
我正在寻找优化这个功能(在代码方面),但也看看是否有一种方法,我可以在后台运行这个,以便管理员可以进行其他事情,而不必坐在那里等待。
感谢您的帮助。
您可能想要尝试WP cron并在此时调度任务,以便它在后台运行。这里有一些资源。基本概念是这样的:
if ( ! wp_next_scheduled( 'pending_to_publish' ) ) {
wp_schedule_single_event($timestamp,'pending_to_publish');
}
add_action('pending_to_publish', 'unzip_to_s3');
