Having my first attempt with PHP templates and i'm a bit confused separating business with presentation logic. I've choosen Dwoo as my template engine as you will see on the example below but my question is independent of Dwoo. I see that what im doing isn't a good logic, it'll confuse the designer and it doesn't really separates PHP/HTML. I can't think any other way of doing it so please if anyone have the time explain me a bit. Cheers. PHP Code <pre><code> $trans = translation('LABEL'); // Load Template Engine $dwoo = new Dwoo(); $dwooTpl = new Dwoo_Template_File('tpl/label.tpl.html'); $dwooData = new Dwoo_Data(); $dwooData->assign('title','Page Title'); <code>if(!isset($_SESSION['logged'])){</code> <code>$dwooData->assign('logged',0);</code> <code>$dwoo->output($dwooTpl,$dwooData);</code> <code>}else{</code> $userID = $_SESSION['userID']; if (!isset($_POST['add'])){ $sql = "SELECT labelName FROM label WHERE userID = $userID"; $rs = mysql_query($sql) or die('Can\'t get label'. mysql_error()); if(mysql_num_rows($rs)){ while ($row = mysql_fetch_object($rs)){ $labels[] = $row->labelName; } $dwooData->assign('labels',$labels); } <pre><code> $dwooData->assign('logged',1); $dwooData->assign('addLabel',0); $dwoo->output($dwooTpl,$dwooData); }else{ $labelName = mysql_real_escape_string($_POST['labelName']); $labelName = trim($labelName); if(strlen($labelName) < 1) { $dwooData->assign('ERR1','Label Name is not valid. You must enter at least 1 letter as Label name.'); }else{ $sql = "SELECT labelName FROM label WHERE userID = '$userID' AND labelName = '$labelName'"; $rs = mysql_query($sql) or die('Can\'t get label '. mysql_error()); if(mysql_num_rows($rs)){ $dwooData->assign('ERR2',"Label '$labelName' already exists."); }else{ $sql = "INSERT INTO label VALUES('','$userID','$labelName')"; mysql_query($sql) or die('Can\'t insert Label '. mysql_error()); $dwooData->assign('INFO','Label added Succesfully.'); } } $dwooData->assign('logged',1); $dwooData->assign('addLabel',1); $dwoo->output($dwooTpl,$dwooData); } </code></pre> } </pre></code> Template Code <pre><code> {include(file='header.tpl.html')} {if $logged == 1} {if $addLabel == 1} {if $ERR1} {$ERR1} {else} {if $ERR2} {$ERR2} {else} {$INFO} {/if} {/if} {else} Add Label: <code><form method="POST" action="label.php"></code> <code>Name: <input type="text" name="labelName"> </code> <code><input type="submit" value="add" name="addLabel"></code> <code></form></code> {foreach $labels label} {escape($label)} {/foreach} {/if} {else} You must login to access this page. {/if} {include(file='footer.tpl.html')} </pre></code>

Guidance

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.
