Upload script mit delete Button?

[pamax]

Hi,
hab mal wieder ein Problem.
Ich will in dieses Upload-script noch ein delete-Button
einbauen, damit man die hochgeladenen Dateien löschen kann.

<?php
$upload_dir = "upload/"; //change to whatever you want.
			 //51200 bytes = 50KB
$size_bytes = 100000; //File Size in bytes (change this value to fit your need)
$extlimit = "yes"; //Do you want to limit the extensions of files uploaded (yes/no)
$limitedext = array(".gif",".jpg",".jpeg",".png",".txt",".nfo",".doc",".rtf",".htm",".dmg",".zip",".rar",".gz",".exe",".msi",".xls",".ppp",".psd",".html",".php",".xml",".css",".aspx",".cs",".fla",".swf",".avi",".mpg",".mpeg",".mp3",".mp4",".wma",".wav",".wmf"); //Extensions you want files uploaded limited to. also you can use: //array(".gif",".jpg",".jpeg",".png",".txt",".nfo",".doc",".rtf",".htm",".dmg",".zip",".rar",".gz",".exe");
		 //check if the directory exists or not.
		 if (!is_dir("$upload_dir")) {
	 die ("The directory <b>($upload_dir)</b> doesn't exist");
		 }
		 //check if the directory is writable.
		 if (!is_writeable("$upload_dir")){
			 die ("The directory <b>($upload_dir)</b> is NOT writable, Please CHMOD (777)");
		 }
 
if($uploadform) // if you clicked the (Upload File) button. "If you submitted the form" then upload the file.
{//begin of if($uploadform).
 
			 //check if no file selected.
			 if (!is_uploaded_file($_FILES['filetoupload']['tmp_name']))
			 {
					 echo "Error: Please select a file to upload!. <br>»<a href=\"$_SERVER[PHP_SELF]\">back</a>";
					 exit(); //exit the script and don't do anything else.
			 }
			 //Get the Size of the File
			 $size = $_FILES['filetoupload']['size'];
			 //Make sure that file size is correct
			 if ($size > $size_bytes)
			 {
					$kb = $size_bytes / 1024;
					echo "File Too Large. File must be <b>$kb</b> KB. <br>»<a href=\"$_SERVER[PHP_SELF]\">back</a>";
					exit();
			 }
			 //check file extension
			 $ext = strrchr($_FILES['filetoupload'][name],'.');
			 if (($extlimit == "yes") && (!in_array($ext,$limitedext))) {
					echo("Wrong file extension. ");
					exit();
			 }
			 // $filename will hold the value of the file name submetted from the form.
			 $filename = $_FILES['filetoupload']['name'];
			 // Check if file is Already EXISTS.
			 if(file_exists($upload_dir.$filename)){
					echo "Oops! The file named <b>$filename </b>already exists. <br>»<a href=\"$_SERVER[PHP_SELF]\">back</a>";
					exit();
			 }
			 //Move the File to the Directory of your choice
			 //move_uploaded_file('filename','destination') Moves afile to a new location.
			 if (move_uploaded_file($_FILES['filetoupload']['tmp_name'],$upload_dir.$filename)) {
				 //tell the user that the file has been uploaded and make him alink.
				 echo "File (<a href=$upload_dir$filename>$filename</a>) uploaded! <br>»<a href=\"$_SERVER[PHP_SELF]\">back</a>";
				 exit();
			 }
				 // print error if there was a problem moving file.
				 else
			 {
				 //Print error msg.
				 echo "There was a problem moving your file. <br>»<a href=\"$_SERVER[PHP_SELF]\">back</a>";
				 exit();

Mit [phpf]unlink[/phpf] kannst du eine Datei löschen. Den Rest solltest du selber können.
