    <p>I have a widget defined with a series of checkboxes that is essentially used to build up a bit flag. So I have a DB column 'access_bits', and I have several checkboxes generated on in the form class, in the format of 'access_bits[]', with the appropriate values (i.e. 1,2,16,1024 etc)</p> <p>following the solution on this post (<a href="https://stackoverflow.com/questions/2254620/symfony-how-to-change-a-form-field-attribute-in-an-action">Symfony: How to change a form field attribute in an action?</a>) - which is simple and sensible - I am able to magically set the attribute for <strong>all</strong> the checkboxes. But how can I target specific ones (preferably by value)? </p> <p><strong>TO CLARIFY:</strong></p> <p>HTML:</p> <pre><code>&lt;input name="user[access_bit][]" value="1" /&gt; Level 1 &lt;input name="user[access_bit][]" value="2" /&gt; Level 2 &lt;input name="user[access_bit][]" value="4" /&gt; Level 3 &lt;input name="user[access_bit][]" value="8" /&gt; Level 4 </code></pre> <p>In the DB I have a column that has a bitwise integer. So for example, to have Level 1 and Level 2 checked, the value in the column would be 3. To have them all checked, the value would be 15.</p> <p>"What I Want" PHP in action.class.php</p> <pre><code>$exampleValue = 4; foreach ($form-&gt;getWidget('access_bit') as $thisWidget) { if ($thisWidget-&gt;getValue() == $exampleValue) { $thisWidget-&gt;setAttribute('checked','checked'); } } </code></pre> <p>... which would cunningly set the checkbox next to Level 3 as ticked.</p> <p>I do not want to use jQuery to do this.</p>

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.
