Help with identifying JPEG

[mat3000000]

This code works in IE9, chrome safari etc, however does not work in IE7 or 8. How else could i do this?

 

$imageData = @getimagesize($name);
if($imageData === FALSE || !($imageData[2] == IMAGETYPE_JPEG))
      $errors[] = 'Image must be a .jpg file.';

check the extension. by exploding the file name.

$string = "lala.mama.jaja.yaya.tata.moemoe.jpg";

$myarray = explode('.', $string);

$extension = $myarray[count($myarray)-1]; // gets the last part
echo $extension; // outputs jpg

From there on you only need to check the value of $extension to what you expect, in this case a jpg.

 

or do something like this:

 

 echo substr(basename($string), -3); // outputs jpg

IE7 & 8, give progressive jpegs the type "image/pjpeg" instead of "image/jpeg"

So try

if($imageData === FALSE || !($imageData[2] == IMAGETYPE_JPEG || !($imageData[2] == 'image/pjpeg'))

The getimagesize returned index [2] is an integer (the IMAGETYPE_JPEG defined constant has the value 2.) Index [4] is the mime type.

 

I would troubleshoot what value you are getting by using var_dump() on the returned value and given that you have an @ on the getimagesize statement to suppress errors, it is likely some other problem is occurring before that point. What php error, if any, do you get when you remove the @?
