    Hi,

    I want to rename files during uploading in add with file name something like random numbers or data&time.

    Thanks in Advance


    My Script Code:

    <?php ini_set("memory_limit", "200000000"); // for large images so that we do not get "Allowed memory exhausted"?>
<?php
// upload the file
if ((isset($_POST["submitted_form"])) && ($_POST["submitted_form"] == "image_upload_form")) {
	
	// file needs to be jpg,gif,bmp,x-png and 4 MB max
	if (($_FILES["image_upload_box"]["type"] == "image/jpeg" || $_FILES["image_upload_box"]["type"] == "image/pjpeg" || $_FILES["image_upload_box"]["type"] == "image/gif" || $_FILES["image_upload_box"]["type"] == "image/x-png") && ($_FILES["image_upload_box"]["size"] < 4000000))
	{
		
  
		// some settings
		$max_upload_width = 2592;
		$max_upload_height = 1944;
		  
		// if user chosed properly then scale down the image according to user preferances
		if(isset($_REQUEST['max_width_box']) and $_REQUEST['max_width_box']!='' and $_REQUEST['max_width_box']<=$max_upload_width){
			$max_upload_width = $_REQUEST['max_width_box'];
		}    
		if(isset($_REQUEST['max_height_box']) and $_REQUEST['max_height_box']!='' and $_REQUEST['max_height_box']<=$max_upload_height){
			$max_upload_height = $_REQUEST['max_height_box'];
		}	

		
		// if uploaded image was JPG/JPEG
		if($_FILES["image_upload_box"]["type"] == "image/jpeg" || $_FILES["image_upload_box"]["type"] == "image/pjpeg"){	
			$image_source = imagecreatefromjpeg($_FILES["image_upload_box"]["tmp_name"]);
		}		
		// if uploaded image was GIF
		if($_FILES["image_upload_box"]["type"] == "image/gif"){	
			$image_source = imagecreatefromgif($_FILES["image_upload_box"]["tmp_name"]);
		}	
		// BMP doesn't seem to be supported so remove it form above image type test (reject bmps)	
		// if uploaded image was BMP
		if($_FILES["image_upload_box"]["type"] == "image/bmp"){	
			$image_source = imagecreatefromwbmp($_FILES["image_upload_box"]["tmp_name"]);
		}			
		// if uploaded image was PNG
		if($_FILES["image_upload_box"]["type"] == "image/x-png"){
			$image_source = imagecreatefrompng($_FILES["image_upload_box"]["tmp_name"]);
		}
		


		$remote_file = "image_files/".$_FILES["image_upload_box"]["name"];
		imagejpeg($image_source,$remote_file,100);
		chmod($remote_file,0644);
	
	

		// get width and height of original image
		list($image_width, $image_height) = getimagesize($remote_file);
	
		if($image_width>$max_upload_width || $image_height >$max_upload_height){
			$proportions = $image_width/$image_height;
			
			if($image_width>$image_height){
				$new_width = $max_upload_width;
				$new_height = round($max_upload_width/$proportions);
			}		
			else{
				$new_height = $max_upload_height;
				$new_width = round($max_upload_height*$proportions);
			}		
			
			
			$new_image = imagecreatetruecolor($new_width , $new_height);
			$image_source = imagecreatefromjpeg($remote_file);
			
			imagecopyresampled($new_image, $image_source, 0, 0, 0, 0, $new_width, $new_height, $image_width, $image_height);
			imagejpeg($new_image,$remote_file,100);
			
			imagedestroy($new_image);
		}
		
		imagedestroy($image_source);
		
		
		header("Location: submitimage.php?upload_message=image uploaded&upload_message_type=success&show_image=".$_FILES["image_upload_box"]["name"]);
		exit;

    I didn't get you.

    I want file automatically take randomly name during uploading.

    for example the file name is Afghan.jpg and after uploading to my website the name changed to something like Afghan1234.jpg or Current date&time+afghan.jpg.


    Thanks

    I hope it stores images in images_files

     $remote_file = "image_files/".$_FILES["image_upload_box"]["name"];
    PHP:
    There for to use Date Declare a variable and go with it
    $date = date("m-d-y");


     $remote_file = "image_files/".$date.$_FILES["image_upload_box"]["name"];
    PHP:

    looking at 
            header("Location: submitimage.php?upload_message=make sure the file is jpg or gif and that is smaller than 4MB&upload_message_type=error");
    PHP:
    is kind of creepy - are you sanitizing $_GET['upload_message']?

    I searched for other script but didn't find good one.

    regarding this script.

    see the request is going to PHP server for generating name, so how can I echo which name is generated for uploaded file???
