I am devolving a profile based website, where profiles will be filled up in HTML form and through PHP it will be store by MYSQL.

My problem is, the Member will upload their profile picture. What I want is to

1. upload the profile picture to the server
2. rename the file to memberID
3. Store the link of the file(i.e. upload\memberid.jpg) to be stored by MySql.

Please help me to solve the issue.
I used the following code

PHP

<?php
$allowedExts = array("jpg", "jpeg", "gif", "png");
$extension = end(explode(".", $_FILES["file"]["name"]));
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 20000)
&& in_array($extension, $allowedExts))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br />";
    echo "Type: " . $_FILES["file"]["type"] . "<br />";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

    if (file_exists("upload/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "upload/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
      }
    }
  }
else
  {
  echo "Invalid file";
  }
?>

but want to rename the file to memberid[some text field value].
I don't want the error message file already exist.

Please please help me.

A couple of points that come to mind
■ You could download phpBB (free forum software) and look at the source
■ When uploading files, it (a) renames them (b) keeps track of the original name and the renamed name
■ using time() would give you a number you could convert to a string and use as a filename - though you would be limited to 1 upload per second or millisecond, whatever the resolution of time is (I forget)
■ You can just comment-out these 3 lines to remove the 'already exists' msg:
if (file_exists("upload/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
■ You could make the following change to rename the file:
$newFilename = calcNewNameForFile();
...
move_uploaded_file($_FILES["file"]["tmp_name"], "upload/".$newFilename);
...

PHP

$photo=$_FILES['photo']['name'];
			$size=$_FILES['photo']['size'];
			$type=$_FILES['photo']['type'];
			if($size > 11120000)
			{
				$err="File size is big";
			}
			else if($type!="image/jpg" && $type!="image/gif" && $type!="image/png" && $type!="image/jpeg")
			{
				$err="File size is big";
			}
			else
			{
				$t="images/";
				$target=$t.basename($_FILES["photo"]["name"]);
				$ext = pathinfo($_FILES['photo']['name'], PATHINFO_EXTENSION);
				while (file_exists($target))
				{
					$photo=uniqid() . '.'.$ext;
					$target=$t.$photo;	
				}
				move_uploaded_file($_FILES["photo"]["tmp_name"],$target);
			}
		}
