validating upload file (form validation)

[nikefido]

I have an upload section in my form.

 

I want the option to upload a file to NOT be required input.

 

I tried testing to see if the

$_FILES['uploaded']

was set using "isset" but that seems to be set every time no matter what.

 

How can I test if there was no file uploaded? (the user didn't hit browse & there's no input in the text field)?

Can you do a print_r on $_FILES['uploaded']? I forgot of the top of my head what the default value for that is so please output that and post here.

Array ( [name] => [type] => [tmp_name] => [error] => 4 => 0 )

 

 

...which doesn't make a lot of sense - I tried to test if 'name' was empty (

if !empty($_FILES['uploaded']['name'])

)

I suppose i could validate based on the error?

There is an error code for no file uploaded:

Yup, just use:

<?php
if($_FILES['uploaded']['error'] === UPLOAD_ERR_NO_FILE) {
    ... do something if file is no file was uploaded ...
}
?>
