How do I insert my imploded array into my database? - php

Question

I'm trying to update permissions of userroles in my application.
Everything works the way I want untill I want to insert the changes into my database.
$permission = $_POST['permission'];
$permissiondb = implode(",", $permission);
print_r($permission)
print_r($permissiondb);
The permission print shows this:
Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 6 [4] => 5 [5] => 4 )
The permissiondb print shows this:
1,2,3,6,5,4
my db query is:
INSERT INTO give_permissions (userrole, permission_id) VALUES ($userrole, $permissions);
When I send the values to my database it inserts a ' 0 ' at the wanted userrole, but instead
I want the system to put in all permissions for the userrole.
I hope I gave enough code for you to help me... can someone help me with this?

Answer 1

You have a list of ids which are being stored in permission_id which suggests that its setup to take a single integer? Thus a list of ids will not work.
a) Change your data type to varchar and wrap $permissions with '$permissions'.
By using this method you would stick with implode(",", $permissions) but there is a better way.
// Your example with modifications
$permission = $_POST['permission'];
$permissiondb = implode(",", $permission);
// INSERT INTO give_permissions (userrole, permission_id)
// VALUES ($userrole, '$permissiondb');
b) Change your data type to varchar and use 'json_encode($permissions)' - This would be the preferable option by many as a shortcut.
When you use json_encode() you store it in a more manageable way. When you encode it you will receive a string in the format of [{1},{2},...] which you can drop into your table quite nicely.
So what about later on when you want to retrieve that permissions list? You use json_decode($permissions) which will then give you a JSON array. For your purposes its easier to cast that json array to a standard array (array)json_decode($permissions) which will take that [{}] string and give you a perfectly standard array(1,2,3,...).
// Your example with modifications
$permission = $_POST['permission'];
$permissiondb = json_encode($permission);
// INSERT INTO give_permissions (userrole, permission_id)
// VALUES ($userrole, '$permissiondb');
c) Setup a corresponding table to take each id and link them. - This would be the perfect ideal.

Change permission data type int to varchar and try this
INSERT INTO give_permissions (userrole, permission_id) VALUES ($userrole, $permissions);
