Body
I wrote a small piece to get a value from a database table according to the input user provides. Quickly here are the events: <ol> <li>User inputs number to an input and submit form</li> <li>That data are supposed to call the controller, and then the controller have to match and grab relevant data from the database table, and pass it to the controller again.</li> <li>Then the controller must pass it to the view, where another text input (readonly) picks up the data as the value.</li> </ol> But what I received was an error: Message: Undefined variable: due_amount Filename: main/new_payment.php Line Number: 148 Line number 148 in new_payment.php is <pre><code>); </code></pre> in the View. This is my Model: <pre><code>function get_by_room_number($room_data) { $this->db->select('due_amount'); $query = $this->db->get_where('rooms', array('room_number' => $room_data), 1); if($query->num_rows()>0) { foreach ($query->result() as $row) { return $row->due_amount; } } </code></pre> This is the Controller: <pre><code>function search_by_number() { $room_data = $this->input->post('room_number'); $due_amount = $this->payments_model->get_by_room_number($room_data); $this->index(); } </code></pre> This is the View: (new_payment.php) <pre><code><?php echo form_open('payments/search_by_number'); ?> <?php $data = array( 'name' => 'total_amount', 'id' => 'appendedPrependedInput', 'class' => 'span2', 'value' => $due_amount ); // Line Number 148 echo form_input($data); ?> <?php echo form_close(); ?> </code></pre>

Guidance

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.
