    <p>I have a backbone.js model with some defaults and an url:</p> <pre><code>var Box = Backbone.Model.extend({ url: "./save.php", defaults: { x: 0, y: 0, w: 1, h: 1 } }); </code></pre> <p>Then I have an instance of this model and I proceed to save it:</p> <pre><code>var box = new Box({ x:10, y:10, w:200, h:200 }); box.save(); </code></pre> <p>Now I want to save this model into a MySQL database using a PHP script "save.php", it goes like this:</p> <pre><code>&lt;?php include('connection.php'); $id = $_POST['cid']; $x = $_POST['x']; $y = $_POST['y']; $w = $_POST['w']; $h = $_POST['h']; mysql_query("INSERT INTO boxes (id, x, y, w, h) VALUES('$id', '$x', '$y', '$w', '$h') ") or die(mysql_error()); ?&gt; echo "Data Inserted!"; </code></pre> <p>I have tried reading many tutorials but I cannot get this simple model save to work. Why is my code not working? Any ideas on how can this be solved?</p> <p>Thanks</p> <p><strong>EDIT: QUICK SOLUTION</strong></p> <p>In the php script, the correct way to obtain the information from the sent JSON object is as follows:</p> <pre><code>$box_data = json_decode(file_get_contents('php://input')); $x = $box_data-&gt;{'x'}; $y = $box_data-&gt;{'y'}; $w = $box_data-&gt;{'w'}; $h = $box_data-&gt;{'h'}; </code></pre> <p>And to store in in the database: </p> <pre><code>mysql_query("INSERT INTO boxes(id, x, y, w, h) VALUES('', '$x', '$y', '$w', '$h') ") or die(mysql_error()); </code></pre> <p>In this way one row will be inserted in the table "boxes" with the information of each one of the attributes of the backbone model Box. The server request method in this case is POST and the id in the table "boxes" is set to auto-increment.</p>

    1. COwhy don't you save it a JSON into one field? Would be extensible. Or a way better approach would be to use a document based database like CouchDB or MongoDB, where data is already saved as JSONs.

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.
