    <p>We did this in our CMS (built on CakePHP 1.2; sorry if there are any significant discrepancies I'm not aware of) using a behaviour. That makes the controller logic very easy (in fact we use a baked controller without any modification at all).</p> <p>Unfortunately TIFF isn't a supported file format in GD (the default image manipulation library in PHP). You'll need to use ImageMagick or an equivalent tool to do the actual conversion itself, but the logic for implementing it in your CakePHP project won't be any different to what I describe here.</p> <p>The behaviour (in our case) was used to generate images as thumbnails as well as page resolution and to convert the uploaded file format into JPEG.</p> <p>In its <code>beforeSave()</code> method it checked that data was specified (and that there was no error), and then pulled the <code>tmp_name</code> value from the posted data (and removed the posted data object).</p> <p>In its <code>afterSave()</code> method, it actually performed the image conversion task itself (putting the generated images in the expected location on disk), then updated any foreign keys on extended models with the uploaded image's ID. We do this in the <code>afterSave()</code> operation so we have a database ID to use to name the files on disk.</p> <p>In its <code>afterDelete()</code> method we unlink the files on disk.</p> <p>Using the behaviour in the model is as simple as telling the model (where <code>ContentImage</code> is the name of the behaviour):</p> <pre><code>var $actsAs = array('ContentImage'); </code></pre> <p>Although we also use the model to define the output directory since we had a few models that implemented the behaviour, and it felt like the right thing to do, e.g. in the model:</p> <pre><code>function getThumbnailDir() { return WWW_ROOT.'img'.DS.'upload'.DS.'thumb'; } </code></pre> <p>and in the behaviour itself the output path becomes:</p> <pre><code>$Model-&gt;getThumbnailDir().DS.$Model-&gt;id.'.jpg' </code></pre>

    1. COReally thanks Kit Grose. If you can provide me the related code developed by you, then I will be able to migrate it in Cake2.X and also will upload that feature on public repository to help others also. I expect a favorable response from you.

    2. CO@Arun sorry, I don't have authority to share the code beyond what I've got here. You should be able to find some similar behaviours on the bakery if you search for `tmp_name`.

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.
