Upload multiple files - Elias - 02-13-2018

Hi,

I want to do upload multiple files and I can do this in cycle.

But first I looked source code of Upload library and found the part of the library code. And I can't understand this code. What does this code?

P.S: If my file field in form has name user[photo] and in do_upload() I passing user while file not selected (empty form submitted) that I get a PHP error:

Code:
Severity: Warning

Message: is_uploaded_file() expects parameter 1 to be string, array given

Filename: libraries/Upload.php

Line Number: 412

instead of a CI message about file not selected.

How can I upload a few files without a cycle?
How can I upload a file with field name like user[photo]?
Why do I have error in the case with empty form? Is it a bug with unhandled error?
What does the code by link above?

Thanks!

It handles array-notation field names, as the comment line there says.

Why are you passing 'user' if the field is 'user[photo]'? Why would you ever expect that to work?

1. You can't, and you shouldn't - that's what loops are made for.
2. Pass 'user[photo]' instead of 'user' ...
3. If you're referring to the error mentioned above - already answered; if not, then I don't know what you're talking about.
4. It allows you to write 'user[photo]'.

Ok, in my controller I do this:

PHP Code:
$uploaded = [];

for($i = 0; $i < 3; $i++)
{
    if ( $this->upload->do_upload("userfile[$i]") )
    {
        $uploaded[] = $this->upload->data('file_name');
    }
    else
    {
        break;
    }
} 

while in my view I have this:

Code:
        <?= form_open_multipart('uploader') ?>

            <fieldset>

                <?= form_label('Select a file:') ?>

                <?= form_upload( ['name' => 'userfile[]'] ) ?>

            </fieldset>

            <fieldset>

                <?= form_label('Select a file):') ?>

                <?= form_upload( ['name' => 'userfile[]'] ) ?>

            </fieldset>

            <fieldset>

                <?= form_label('Select a file:') ?>

                <?= form_upload( ['name' => 'userfile[]'] ) ?>

            </fieldset>

            <?= form_submit('submit', 'Submit', 'accesskey="s"') ?>

        <?= form_close() ?>

But nothing uploads...
