    <p>check the object has data. you can use a combination of following</p> <pre><code>isset- Determine if a variable is set and is not NULL is_null - Finds whether a variable is NULL empty — Determine whether a variable is empty is_array — Finds whether a variable is an array is_object — Finds whether a variable is an object </code></pre> <p>You can use something like(if the number of rows are 0, set the object to null).</p> <pre><code>If(!is_null($this-&gt;gallery)) { //show data } else { //show a msg } </code></pre> <p>You can just check if the <code>$this-&gt;gallery</code> is an object.</p> <pre><code>If(is_object($this-&gt;gallery)) { //show data } else { //show a msg } </code></pre> <p>Depending on the result set choose the above wisely. If you can post a <code>print_r</code> I can tell you exactly what you have to use.</p> <p><em><strong>UPDATE WITH RESPECT TO THE QUESTION</em></strong></p> <blockquote> <p>Warning: array_splice() expects parameter 1 to be array, object given in</p> </blockquote> <p>The reason it may not work is because <code>$this-&gt;_gallery</code> may not be an array.</p> <blockquote> <p>stdClass Object ( [id] => 0 ) &lt;-- this is an object not an array. if you are to call array_slice() function, 1st parameter should be an array. </p> </blockquote> <p>To check if something is an array, you can do:</p> <pre><code>is_array($this-&gt;_gallery); // returns true or false </code></pre> <p>If it is an array, you can then call <code>array_slice()</code>.</p> <p>Hope this helps. If you have any problems ask here.</p>

    1. COGreat!, I've tried it and got it to work, although there is one extra error. You can find it at the bottom section of my edited question above.

    3. COThank you for you're reply, I understand now what is going wrong. But the problem is in the model code I guess. When the query returns data it makes an array out of it, when it doesn't return data it doesn't make an array out of it. Is there a way I can solve this in the model part of my code ?

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
