    <p>I created some templating system to help me output database items in a skinnable way. It works like this:</p> <pre><code>$tpl = "&lt;html&gt; &lt;body&gt; &lt;div&gt;&lt;span class="item"&gt;Favourite food:&lt;/span&gt;&lt;span class="content"&gt;{item1}&lt;/span&gt;&lt;/div&gt; &lt;div&gt;&lt;span class="item"&gt;Hobby:&lt;/span&gt;&lt;span class="content"&gt;{item2}&lt;/span&gt;&lt;/div&gt; &lt;div&gt;&lt;span class="item"&gt;Allergies:&lt;/span&gt;&lt;span class="content"&gt;{item3}&lt;/span&gt;&lt;/div&gt; // up to 500 more lines like this &lt;/body&gt; &lt;/html&gt;"; $output = str_replace( array('{item1}','{item2}','{item3}') ) , array($database['item1'],$database['item2'],$database['item3']) , $tpl ); echo $output; </code></pre> <p>Now I the problem is: Not every database item has content necessarily - so, currently I get output like this</p> <blockquote> <p>Favourite food: Banana Hobby: {item2} Allergies: Apple</p> </blockquote> <p>Is there any way to use this kind system and to leave out the lines that don't have a database entry? The output should then be like this:</p> <blockquote> <p>Favourite food: Banana Allergies: Apple</p> </blockquote> <p>How could I achieve this?</p> <p>UPDATE: The Description text may vary, as well, therefore I updated the example code. And I would like to avoid foreach or for-loops because then the templating itself is broken. I want to be able to insert random HTML. Using smarty or another templating system is not feasible at this moment. But I could provide a third array with descriptions. </p> <p>UPDATE 2: I thought that maybe a preg_replace on $output might do the trick? so this would mean "IF there is a html tag that contains {} brackets somewhere in it on $output THEN erase the whole tag from to (I updated my code accordingly) what do you think? do you know any reg_expression that could 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.
