    <p>I'm fairly new to php and I am trying to figure how do I set an optional parameter after the first optional parameter?</p> <p>For example I have the following code:</p> <pre><code>function testParam($fruit, $veg='pota',$test='default test'){ echo '&lt;br&gt;$fruit = '.$fruit; echo '&lt;br&gt;$veg = '.$veg; echo '&lt;br&gt;Test = '.$test; } </code></pre> <p>If i make the following calls:</p> <pre><code>echo 'with all parama'; testParam('apple','carrot','some string'); //we get: //with all parama //$fruit = apple //$veg = carrot //Test = some string echo '&lt;hr&gt; missing veg'; testParam('apple','','something'); //we get: //missing veg //$fruit = apple //$veg = //Test = something echo '&lt;hr&gt; This wont work'; testParam('apple',,'i am set'); </code></pre> <p>I want to try make a call so that in the last example I show 'pota' as the default $veg parameter but pass into $test 'i am set'.</p> <p>I guess I can pass 0 into $veg then branch it in the code to say if $veg =0 then use 'pota' but just wondered if there's some other syntax as i cant find anything in php.net about it.</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.
