使用SWFUpload创建缩略图

Question

我正在尝试CMS照片库，需要在upload.php文件的末尾创建缩略图。我有一个名为create_square_image的函数，在'showphotos.php'页面上运行时可以正常工作。但是，我不希望每次有人查看页面时都会运行它。我尝试将以下内容添加到SWFUpload ...

// Process the file
/*
    At this point we are ready to process the valid file. This sample code shows how to save the file. Other tasks
     could be done such as creating an entry in a database or generating a thumbnail.

    Depending on your server OS and needs you may need to set the Security Permissions on the file after it has
    been saved.
*/

$thumb_save = "uploads/thumbs/thumb_" . $_FILES[$upload_name]["tmp_name"];
create_square_image($_FILES[$upload_name]["tmp_name"],$thumb_save,100);

if (!@move_uploaded_file($_FILES[$upload_name]["tmp_name"], $save_path.$file_name)) {
    HandleError("File could not be saved.");
    exit(0);
}

exit(0);

create_square_image函数使用以下格式： create_square_image（string $ filename，string $ destination，size）

我已经尝试了几次，它会保存图像而不是缩略图。

将/uploads/thumbs/上的权限设置为777.您还可以尝试指定该位置的绝对路径。要查看绝对路径，请使用以下代码：echo getcwd();
