上传后重命名某些文件? [英] Renaming certain files after upload?

问题描述

大家好，我有一个脚本进行了部分编辑，以仅接受要上载的某些文件类型，例如； JPG，PNG，JPEG等.该脚本最初是"uploadify脚本"的一部分，是php的新功能，因此im很难解决我如何添加功能以在后端重命名文件，这样我就不会出现重复或错误在上传时，但保留前端的原始名称.如果一切都有意义，请先谢谢-Cody

Hi all, i''ve got a script that i''ve part edited to accept only certain file types to be uploaded, eg; JPG, PNG, JPEG etc. the script is originally part of the "uploadify script", im new to php so im finding it hard to work out how i can add a function to rename files on the backend so i dont get duplicates or errors on upload, but keep original names for the frontend. if this all makes sense, thanks in advance - Cody

if (!empty($_FILES)) {
	$tempFile = $_FILES['Filedata']['tmp_name'];
	$targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
	$targetFile =  str_replace('//','/',$targetPath) . $_FILES['Filedata']['name'];
	
	
	$fileTypes = array('jpg','jpeg','gif','png'); // File extensions
	$fileParts = pathinfo($_FILES['Filedata']['name']);
	
	if (in_array($fileParts['extension'],$fileTypes)) {
		move_uploaded_file($tempFile,$targetFile);
		echo '1';
	} else {
		echo 'Invalid file type.';
	}
}
?>
