Advanced Addon "array_Keys() Expects Parameter 1 To Be Array, String Given"

Store Builder in detail Configuration
#1

Hi,

I'm currently using the advanced-addon tutorial as reference to develop an add-on that basically displays the viewed categories but, I'm having an issue with array_keys().

This is the index.post.php file:

if (!defined(‘BOOTSTRAP’)) {

die(‘Access denied’);

}


use Tygh\Registry;


$viewed_categories = db_get_array(‘SELECT * FROM ?:advanced_addon_data’);


if (!empty($viewed_categories)) {

foreach ($viewed_categories as $key => $category_data) {

// fn_print_r(array_keys($category_data[‘categories’]));

$category_data[‘user_name’] = fn_get_user_name($category_data[‘user_id’]);

$category_data[‘categories’] = unserialize($category_data[‘categories’]);

$category_data[‘categories’]  = fn_get_category_name(array_keys($category_data[‘categories’]));


    $viewed_categories[$key] = $category_data;
}

Registry::get('view')->assign('viewed_categories', $viewed_categories);



}

I'm getting this error when I activate the addon: 

PHP Warning
Message
array_keys() expects parameter 1 to be array, string given

Error at

C:\xampp\htdocs\marketplace\app\addons\advanced_addon\controllers\backend\index.post.php, line: 29

Did you guys faced a similar error ?

Thanks.

Hello

Please check that $category_data['categories'] is array.

print "

";


print_r($category_data['categories']);


print "
";

Best regards

Hi,

It's not an array, I'm getting a string, I used the explosion function to separate the categories IDs to fix this. 

if (!empty($viewed_categories)) {
    foreach ($viewed_categories as $key => $category_data) {
        // fn_print_r($category_data['categories']);
        $category_data['user_name'] = fn_get_user_name($category_data['user_id']);
        $category_data['categories'] = unserialize($category_data['categories']);
        // fn_print_r(array_keys(explode(" ",$category_data['categories'])));
        $category_data['categories']  = fn_get_category_name($category_id = array_keys(explode(" ", $category_data['categories'])));
        $viewed_categories[$key] = $category_data;
        // fn_print_r($viewed_categories);
    }

Registry::get('view')->assign('viewed_categories', custom_sort($viewed_categories));



}

I also sorted the users and counted the categories numbers.

Could be done with better ways...
