我有一個for循環，並且在其中我上傳了多個圖像。上傳圖片後，我會通過wp_mail()向管理員發送電子郵件通知。PHP：在for循環中只返回一次函數
事情工作正常，併發送電子郵件通知。然而問題是通知電子郵件發送按照圖像計數。意思是如果上傳1張圖片比4張通知電子郵件中的一張通知郵件（因爲它在循環中）。不過，我希望通知只發送一次，無論是一個或10個圖像。
這裏是我的全部代碼：一個變量（下文$ MSG）和修改信息循環的每一次迭代
global $wpdb, $post;
$upload_path = wp_upload_dir();
$post_id = $post->ID;
$upload_dir = $upload_path['basedir'].'/review-media/'.$post_id.'/'.get_current_user_id().'/';
$thumbnail_dir = $upload_dir.'thumbnail/';
$upload_url = $upload_path['baseurl'].'/review-media/'.$post_id.'/'.get_current_user_id().'/thumbnail/';
self::create_path($thumbnail_dir);
if (isset($_FILES['photo']) === true) {
$errors = array();
$allowed_ext = array('jpg', 'jpeg', 'png', 'gif');
$files = $_FILES['photo'];
for($x = 0; $x < count($files['name']); $x++) {
$file_name = $files['name'][$x];
$file_ext = strtolower(end(explode('.', $file_name)));
$file_size = $files['size'][$x];
$file_tmp = $files['tmp_name'][$x];
if($file_tmp)
list($img_width, $img_height) = getimagesize($file_tmp);
$min_img_width = 1;
$min_img_height = 1;
$max_img_width = 2000;
$max_img_height = 2000;
if (!$file_tmp) {
$errors[] = '<p>Please select the file</p>';
}
if (($file_tmp) && (($img_width > $max_img_width) || ($img_width < $min_img_width)) && (($img_height > $max_img_height) || ($img_height < $min_img_height))) {
$errors[] = '<p>Size of <strong>'.$file_name.'</strong> must be within '. $min_img_width .'px to '. $max_img_width .'px</p>';
}

unlink($file_tmp);
}

//crop and resize to images and thumbnails
$target_file = $upload_dir.$file_name; // original file

self::resize_image($target_file, $med_file, $med_width, $med_height, $file_ext);
// crop image uisng medium resized image
self::crop_thumbnai(file_exists($med_file) ? $med_file : $target_file, $thumbnail, $thumb_width, $thumb_height, $file_ext);
// delete medium resized file after thumbnail creation.
if (file_exists($med_file))
unlink($med_file);
self::insert_image($file_name);
//self::get_uploaded_image();
echo '<div class="upload-status-thumb">';
echo '<img src="'.$upload_url.$file_name.'" alt="imge" />';

// send notification email to admin on image upload
self::email_notification($post_id);

循環*後發送通知*一次，而不是在每個循環迭代。 – deceze 2013-02-17 12:22:47
但比如何檢查表格是否已提交？不過，我試圖放置循環後，但它仍然發送上傳時間圖像的數量。如果你不能介意的話，你可以給予更多的否定票:)只要我學到新東西:) – 2013-02-17 12:24:29
更具體地說，因爲如果沒有錯誤，你正在發電子郵件記錄'$ success = true'，你的腳本當前發送一封電子郵件並且在循環之外，詢問「if（$ success）」，如果是，則發送電子郵件。 – Popnoodles 2013-02-17 12:24:48
