How do I check if a file is selected for <input type=“file”> in PHP?

Question

I want to check if the user has selected an image for upload. What is the php script to do that after the user has clicked submit...

I tried file_exist(), but that expects a string rather than an array and it seems that only works for an absolute path. Since I don't know which folder the user is going to upload from, this doesn't work.

Can someone help?

Answer 1

Take a look at the $_FILES superglobal .

If you do a print_r($_FILES) , you will see everything you need.

Answer 2

You need to use the super global variable $_FILES .
