Getting the extension of a file

WorrNemesis

Busy at work on my forums and over 2k lines of code and I come to making it upload pictures. I've got it all worked out except I can't make it figure out if it's supposed to be a .gif or a .jpeg. What do I do. I tried

if ($userfile["type"] == "image/gif")
     $extension = ".gif";
elseif ($userfile["type"] == "image/jpeg")
     $extension = "jpeg";
else
     error ("Wronge file type, please press back and try again.")

Error is a function that gives a missage box displaying that argument. I've tried it and it doesn't work. Is there some other way?

What doesn't work about it? What kind of an error do you get?

Also, your jpeg instance doesn't put in a "." before the extension. You may want to check that out.

The If statements always return false. Without them it saves the file without an extension making it useless.

How are you retrieving $userfile? Post the code for the html form here.

That's the HTML form that given from the PHP, I took out all the variables of text colors and that kind of stuff in it.

<form action="upload.php" method="post">
<font face="arial" size="2" color="000000"><b>Upload Picture:</b></font>
<input type="hidden" name="MAX_FILE_SIZE" value="51200">
<input name="userfile" type="file">
<input type="submit" name="submit" value="Upload"><br><br>
</form>

It' just for uploading a gif or jpeg for use in the forum. I've got it uploaded, but when I copy the temporary file it doesn't take the extension.

My mistake on forgetting the '.', but that isn't the problem.

Ok...then you should be able to use something similar:

if ($_FILES['userfile']['type'] == "image/gif")
{
 $extension = ".gif";
}

Hope that works,

Talk about doing something stupid. I just noticed I made the variable $userfile after I had that if statement... I figured it out when the $_FILES['userfile']['filetype'] worked.

Thank You.
