array_filter() expects parameter 1 to be array in PHP

Question

i have an issue with a line for several days.

Here is my code :

$files = array();
$count = count(array_filter($_FILES['fichier']['name']));
echo $count;

for($i=0;$i<$count;$i++){
    array_push($files, $_FILES['fichier']['tmp_name'][$i]);
}

This code is in a form, but when i submit my form, i have this error message :

Warning: array_filter() expects parameter 1 to be array, null given in...

This part of code works in FR version, but when i tried to copy/paste in EN version, it doesn't work.

I've tried everything, nothing happens.

Thanks.

EDIT :

var_dump(array_filter($_FILES['fichier']['name']));

return me this :

NULL

when i'm trying to upload 1 or many files.

Solution

I think when you see this error you can use this:

<td>{{ is_array($client->phone) ? implode($client->phone, '-') : $client->phone }}</td>

array_filter($_FILES['fichier']['name']) returns a string containing the file name that has been uploaded under the field fichier. You edit the question to elaborate your requirement, may be we could help. What is it that you cant this $count to be?

[u_mulder]

var_dump($_FILES)

$count return me 0 everytime even if i'm uploading 1 or many files. This part of code works good in FR version, i can't understand the problem.

@u_mulder var_dump($_FILES) returns to me : array(0) { } , even if i'm uploading two files, for example

[u_mulder]

So the real problem is that $_FILES empty. Check your form. Do you have enctype attribute for a form?

you're right @u_mulder , i just put a enctype attribute on my form, then i put name="file[]" on my input field for multiple files, and it works. Thanks for your time.
