    <p>I'll get straight to it.</p> <p>layout.html</p> <pre><code>&lt;table&gt; &lt;tr&gt; &lt;td&gt;&lt;div id="corner1"&gt;&lt;/div&gt;&lt;div id="c11"&gt;&lt;/div&gt;&lt;div id="c12"&gt;&lt;/div&gt;&lt;/td&gt; &lt;td&gt;&lt;div id="corner2"&gt;&lt;/div&gt;&lt;div id="c21"&gt;&lt;/div&gt;&lt;div id="c22"&gt;&lt;/div&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;div id="corner3"&gt;&lt;/div&gt;&lt;div id="c31"&gt;&lt;/div&gt;&lt;div id="c32"&gt;&lt;/div&gt;&lt;/td&gt; &lt;td&gt;&lt;div id="corner4"&gt;&lt;/div&gt;&lt;div id="c41"&gt;&lt;/div&gt;&lt;div id="c42"&gt;&lt;/div&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;input type="hidden" value="12" name="tableid" /&gt; </code></pre> <p>main.js</p> <pre><code>populateID = setInterval(Populate, 1000); function Populate() { $.ajax({ url: 'jquery/populate.php', data: 'tableid=' + $("#tableid").val(), success: function(data) { fillem(data); } }); } function fillem(data) { if(data.c1) { $("#c11").html(data.c1); $("#c12").html(data.filler); }else{ $("#c11").html(data.filler); } if(data.c2) { $("#c21").html(data.c2); $("#c22").html(data.filler); }else{ $("#c21").html(data.filler); } if(data.c3) { $("#c31").html(data.c3); $("#c32").html(data.filler); }else{ $("#c31").html(data.filler); } if(data.c4) { $("#c41").html(data.c4); $("#c42").html(data.filler); }else{ $("#c41").html(data.filler); } if(data.timer) { $("#timer").html(data.timer); }else{ $("#timer").html(""); } if(data.corner) { $("#corner" + data.corner).html("ACTIVE"); } } </code></pre> <p>I'm pretty sure this could be done in a more efficient way, I don't care if it involves changing the DOM structure.</p> <p>For example, It does sound bad to always have 4 "corner" divs when no two of them will be used simultaneously. And since the ajax response will change upon every request, sometimes a div "flashes" quickly when being populated with new data, which is also annoying.</p> <p>Thanks for reading.</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.
