I have this file input:
<input type="file" name="photo[]" multiple="yes">
What I want is, when someone uploads a file/files to it, I want to alert them how many files were uploaded (altogether). Like if I upload 3 files, it will alert "3 files were uploaded". And if I add 2 more files it will alert "5 files were uploaded" (adding the 2 files uploaded before).
