    <p>I am creating an update billing information section for my users. I am currently passing a masked credit card number to the form. I do not want the user to have to update their credit card information if they only want to update say their billing address.</p> <p>I am attempting to use regex to match the masked credit card, but I have not been able to get ANY regex patterns to match... Even 100% wildcards...</p> <p>Here are couple of examples of what I have tried...</p> <p>================================================================</p> <p>The Masked Credit Card Value Is XXXXXXXXXXXX0012</p> <p>================================================================</p> <pre><code>'creditcard' =&gt; array( 'creditcard' =&gt; array( 'rule' =&gt; array('cc', 'all', false, '^[.]+$'), 'message' =&gt; 'Required', 'allowEmpty' =&gt; false, 'required' =&gt; true, ), ), </code></pre> <p>================================================================</p> <pre><code> 'creditcard' =&gt; array( 'creditcard' =&gt; array( 'rule' =&gt; array('cc', 'all', false, '/^[X]+[0-9](4,)$/'), 'message' =&gt; 'Required', 'allowEmpty' =&gt; false, 'required' =&gt; true, ), ), </code></pre> <p>================================================================</p> <pre><code> 'creditcard' =&gt; array( 'creditcard' =&gt; array( 'rule' =&gt; array('cc', 'all', false, '/^[x]+[0-9]+$/i'), 'message' =&gt; 'Required', 'allowEmpty' =&gt; false, 'required' =&gt; true, ), ), </code></pre> <p>Any Ideas Are Greatly Appreciated!</p> <p>Thank You!!</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.
