Modify following line to get mysql error if any..

This will give you a fair idea about the problem.

$add_member = mysql_query($insert) or die(mysql_error());

Ignore my last comment....

Sorry of inconvenience caused.

What do you mean disappears? Do you mean that when you do

$inputid = $_GET['id'];
echo $inputid;

that the echo shows nothing?

By the way, you should ALWAYS check ALL inputs for safety. For example, if id is an integer:

$inputid = floor($_GET["id"]); will ensure that it is an integer, and not some SQL Injection hacking.

Once you have a safe $inputid, then

$new_id = 'img'.$inputid;
echo $new_id ;

I call this page like this, upload.php?id=2 so when uploading I want the image to be renamed img2.jpg

So when I load the page :-
$_GET['id'];
$new_id = 'img'.$_GET['id'];
-------------

When I call the page upload.php?id=2 , $new_id = "img2". But when I hit the upload button the page gets refreshed and that time it's not calling any id so I'm getting only "img"

so all I want is to pass the id for $new_id whil page get refreshed.

See the complete code for the page

<?php 
$_GET['id'];
		
$new_id = 'img'.$_GET['id'];

echo $new_id ;
						
$upload_errors = array(

	UPLOAD_ERR_OK 				=> "No errors.",
	UPLOAD_ERR_INI_SIZE  	=> "Larger than upload_max_filesize.",
  UPLOAD_ERR_FORM_SIZE 	=> "Larger than form MAX_FILE_SIZE.",
  UPLOAD_ERR_PARTIAL 		=> "Partial upload.",
  UPLOAD_ERR_NO_FILE 		=> "No file.",
  UPLOAD_ERR_NO_TMP_DIR => "No temporary directory.",
  UPLOAD_ERR_CANT_WRITE => "Can't write to disk.",
  UPLOAD_ERR_EXTENSION 	=> "File upload stopped by extension."
);




if(isset($_POST['subtrue'])==1){
	
        if(isset($_POST['submit'])){
		$a=($_FILES["file_upload"]);
		$jpage= $a['type'];	
		$tmp_file=$_FILES['file_upload']['tmp_name'];
		$target_file=basename($_FILES['file_upload']['name']);
		$upload_dir='thumbs';
		//if(move_uploaded_file($tmp_file,$uplaod_dir,'/'.$target_file))
	if($jpage=='image/jpeg'||$jpage=='image/pjpeg'){
	
		if(move_uploaded_file($tmp_file, $upload_dir."/"."$new_id.jpg")) {
		
		medium($new_id);	
		
		
	$picview="$new_id.jpg";
		$message="File uploaded successfully";
	
		}//end move if

		else{

		$error = $_FILES['file_upload']['error'];
		$message = $upload_errors[$error];
		}//end else move
		
	}//end of if jpeg
	else{
		$message="You can uplod only JPEG File ...";
	}//end else Jpeg

}// end of post submit 
		
		
						
					
				
	 }//end of !pho
	 else
	 { 
	  $pho_error="Pleas Enter Photo Title";
