Question

I have a problem with looping through the pulled info form my database (MySQL)

I want to pull all the ID from the Forum table, like this:

SELECT ID FROM Forums

then loop through all the ID’s and run

SELECT ID FROM Catagory WHERE Forum_ID = ?

This is the same in proper php:

$profile=$db->prepare('SELECT ID FROM Forums ');
$profile->execute();
$forums = $profile->fetch();

foreach ($forums as &$forum_ID) {

    // some code

    $profile=$db->prepare('SELECT ID FROM Catagories WHERE Forum_ID = ?');
    $profile->bindValue(1, $forum_ID);
    $profile->execute();
    $catagories = $profile->fetch();

    foreach ($categories as &$category_ID ) {

        //some more of my code
    }
}

With this code i get an error:

Undefined variable: categories

Please do not mind the spelling errors they are spelled that way in my database, im dyslectic

Thanks in advance

EDIT: For this test i made sure there is something to return by the SQL server

Answer 1

We don’t mind the spelling errors. But PHP minds,

change $catagories into $categories.
