[RESOLVED] Upload image and get details

[naskar]

Hi there everyone, I'm trying to get a script that uploads a User specified image file and lets the user edit it with text. It's basically a 'banner' generator that will take in the users image, resize it and include the specified text on a transparent overlay.

<?php

$tmp_name = $_FILES["upload"]["tmp_name"];
echo "\"".$tmp_name."\"";
$name = $_FILES["upload"]["name"];
$webserver = $_SERVER['DOCUMENT_ROOT'];
$fullname = $webserver."/$name";



if (move_uploaded_file($tmp_name, "uploads/$name")) 
{

echo "File is valid, and was successfully uploaded.\n";
echo "test number is ";

}
else 
{
    echo "Possible file upload attack!\n";
}


?>

So far that works and the image gets moved into the uploads folder. However, when I try :

if (move_uploaded_file($tmp_name, "uploads/$name")) 
{
	if (exif_imagetype("uploads/$name") == IMAGETYPE_GIF)
	{
		echo "Its a GIF";
	}
	else
	{
		echo "its a png";
	}

echo "File is valid, and was successfully uploaded.\n";

}
else 
{
    echo "Possible file upload attack!\n";
}

Nothing happens. It isn't checking the type of image the file is 😕
Any ideas? Thanks in advance

I would do something like:

if (move_uploaded_file($tmp_name, "uploads/$name")){
     $offset = strpos("uploads/$name",".");
     $ext = substr("uploads/$name",$offset);

 echo "The file type is a : ".$ext;
}

Thanks rsmith, what you suggested is a more practical approach 🙂 Appreciate the help!
Just one last question, I want to continue editing the submitted image, Do i do so in that IF condition or is there a better way to go about it?

If you're looking to do editing of the image, you'll need to use either ImageMagick or the GD library.
