    <p>I'm working with a config file that I have create in order to store users. This surely wasn't what the configs were intended to be used for, but it's an extremely small application and I think that it would be a nice solution.</p> <p>My array looks like this:</p> <pre><code>$config['users'] = array(array('username' =&gt; 'username', 'password' =&gt; 'password')); </code></pre> <p>This works well. I can retrieve the information quick and easy. BUT, if I try to write a new array (a new user) to the config file I get this error: Illegal offset type in isset or empty</p> <p>I'm using <code>$this-&gt;config-&gt;item('users', array('username' =&gt;....))</code> which doesn't appear to support arrays.</p> <p>How can I write arrays to my config variable? Is there another way?</p> <p>EDIT: Alright, the error is fixed thanks to the answer given by phirschy. I was so sure in my head that I could use config->item() that I didn't check the manual for a config->set_item()... BUT, it still doesn't work. Here is the specific code:</p> <pre><code> $users = $this-&gt;config-&gt;item('users'); array_push($users, array('username' =&gt; $this-&gt;input-&gt;post('username'), 'password' =&gt; $this-&gt;input-&gt;post('password'))); $this-&gt;config-&gt;set_item('users', json_encode($users)); echo json_encode($users); </code></pre> <p>This code is called via Ajax, and I have an alert box to see if it the values are correct. They are. And as you can see, I've tried storing it as json instead of array as well.... but that doesn't work either. Help please?</p> <p>thank you</p>

    1. COWhatever the scope of your application, I'd still recommend against using a config file to store usernames and passwords. Security is a much bigger concern here than size. That said, if you still want to use a config file for this, just be sure you're not storing the passwords in plain text and that you set proper permissions on your config file.

    2. COI will, don't worry. :) It's also partly because I have no idea how to do it differently. I can do it with MySQL, but I've never worked with file storage before and I don't want to involve a db.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
