File uploading question

[graham23s]

Hi Guys,

 

I am making an upload form for users to upload they're pictures (single upload) i was curious as to what a lot of other members do in terms of logic i'e

 

whats the first thing you check for once the form is submitted? is it the mime type,extension,size and in what order i know there is a lot of different ways to do it, but wasn't sure if there was a certain procedure or order to do them in?

 

any advice would be greatthanks guys

If it's an image, then getimagesize() will return a value. If it doesn't then it isn't an image. You can check it in that way. You can check the mime type with image_type_to_mime_type(exit_imagetype($filename));.
