    <p>I'm really stumped on this one. I have this array variable <code>$banner_image_description</code>. When I print it I get <code>Array ( ['title'] =&gt; dafha ['price'] =&gt; adhfadhf )</code>. </p> <p>Now, what I'm trying to do is check the length of the value at 'title' and make sure it is more than 2. So when I run :</p> <pre><code>if (isset($this-&gt;request-&gt;post['banner_image'])) { foreach ($this-&gt;request-&gt;post['banner_image'] as $banner_image_id =&gt; $banner_image) { foreach ($banner_image['banner_image_description'] as $language_id =&gt; $banner_image_description) { print_r($banner_image_description); echo('&lt;br/&gt;'); if ((utf8_strlen($banner_image_description['title']) &lt; 2) || (utf8_strlen($banner_image_description['title']) &gt; 64)) { $this-&gt;error['banner_image'][$banner_image_id][$language_id] = $this-&gt;language-&gt;get('error_title'); } } } } </code></pre> <p>I get <code>Notice: Undefined index: title</code> and I have no idea why. I thought this was the correct way to go about getting the value at 'title' and I know the index is there and the value is there.</p> <p>I am pretty sure that the array is being populated by POSTing form values:</p> <pre><code>if (isset($this-&gt;request-&gt;post['banner_image'])) { $banner_images = $this-&gt;request-&gt;post['banner_image']; } </code></pre> <p>Here is what the form values look like:</p> <pre><code>&lt;input type="text" name="banner_image[&lt;?php echo $image_row; ?&gt;][banner_image_description][&lt;?php echo $language['language_id']; ?&gt;]['title']" value="&lt;?php echo isset( $banner_image['banner_image_description'][$language['language_id']]['title']) ? $banner_image['banner_image_description'][$language['language_id']]['title'] : ''; ?&gt;" /&gt; &lt;img src="view/image/flags/&lt;?php echo $language['image']; ?&gt;" title="&lt;?php echo $language['name']; ?&gt;" /&gt;&lt;br /&gt; </code></pre>

    1. COIs it like `Array ( ['title'] => dafha ['price'] => adhfadhf )` or `Array ( ['title'] => 'dafha', ['price'] => 'adhfadhf' )`?

    3. COBUt is it the way you define it or the result of `print_r($var)`? Because if you are defining it, should be the way I said the 2nd.

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.
