+--- Thread: Proper way to get array from session (/showthread.php?tid=79080)
Proper way to get array from session - sfarzoso - 04-17-2021
I have a session which contains an item called "error", this item contains an array with the following structure:
array(1) { ["meta.featured_image"]=> string(60) "Il file meta.featured_image supera le dimensioni consentite." }
I'm trying to print the item featured_image, so I did
this:
PHP Code:
<?= session('error.meta.featured_image') ?>But the code above returns NULL
but if I do
PHP Code:
<?= session('error')['meta']['featured_image'] ?>works but I need to check if the index exists to prevent error, there is no way to get the featured_image index directly in the session?

I do not believe that sessions work with the dot notation on session arrays.

PHP Code:
session('error.meta.featured_image')
//equal
session('error')['meta']['featured_image']
// and match
['error' => ['meta' => ['featured_image' => '...']]]
// and does not match
['error' => ['meta.featured_image' => '...']]

I already tried with the first one and I get NULL how is that possible? ?
RE: Proper way to get array from session - iRedds - 04-18-2021
This will return null because there is no matching data.
You cannot get the data using:
session('error')['meta']['featured_image']
for ['error' => ['meta.featured_image' => '...']]

for ['error' => ['meta.featured_image' => '...']]
the input I have is this:
PHP Code:
<input type="file" id="featuredImage" accept=".png, .jpg, .jpeg" name="meta[featured_image]">
I guess session('error.meta.featured_image') should be correct?

I will show you an example of how you can get out of this situation.
PHP Code:
// route
$routes->add('/', 'Home::index');
// in controller
public function index()
{
if ($this->request->getMethod() !== 'get') {
if (! $this->validate(['a.c' => 'required'])) {
return redirect()->to('/')->withInput();
} else {
d('win');
}
} else {
session();
return view('template', ['validator' => Services::validation()]);
}
}
// template
<?php /** @var Codeigniter\Validation\Validation $validator */ ?>
<h1>error: <?= $validator->getError('a.c')?></h1>
<form method="post" action="/">
<input type="text" name="a[b]" value="aa">
<input type="submit">
</form>
Anyway, I added a PR to access the key containing the dot using dot notation.
