title: Grocery Crud set relation between 3 tables
body: <p>I have 3 sql tables and they are with this form.</p>
  
  <p><strong>TEST</strong></p>
  
  <ul>
  <li>test_id </li>
  <li>test_name</li>
  </ul>
  
  <p><strong>EXAMPLE</strong></p>
  
  <ul>
  <li>example_id</li>
  <li>example_test_id</li>
  </ul>
  
  <p><strong>SOMETHING</strong></p>
  
  <ul>
  <li>something_id</li>
  <li>something_example_id</li>
  </ul>
  
  <p>So i want to take the name of the TEST table among with the id 
  and send it to the table EXAMPLE, and then the example_id should be sent to SOMETHING table.
  Finishing the relation i want the name of the TEST table to be shown by the example_id in the SOMETHING table.</p>
  
  <p>We have tried this </p>
  
  <pre><code> $crud-&gt;set_relation_n_n('something','example','test','example_id','example_test_id','test_name');
  </code></pre>
  
  <p>And it takes the id of the TEST and it saves it to example_test_id but we want it to be saved at something_example_id and show the test_name.
  All the tables have foreign keys and primary keys.
  Hope you understand.</p>
