    <p>i'm trying to fill the form with database information when user changes the category(select tag changes). here is my code.</p> <pre><code>&lt;form onsubmit='return false'&gt; select&lt;select id="select"&gt; &lt;option value='5'&gt;5&lt;/option&gt; &lt;option value='6'&gt;6&lt;/option&gt; &lt;option value='7'&gt;7&lt;/option&gt; &lt;option value='8'&gt;8&lt;/option&gt; &lt;option value='9'&gt;9&lt;/option&gt; &lt;option value='10'&gt;10&lt;/option&gt; &lt;/select&gt; fname&lt;input type="text" id='fname' name="fname" /&gt;&lt;br /&gt; lname&lt;input type="text" id='lname' name="lname" /&gt;&lt;br /&gt; &lt;/form&gt; &lt;script type="text/javascript"&gt; $(document).ready(function(){ $("#select").change(function(){ selectid = $(this).val(); // using post method to get firstname $.post("retreive.php", {selectid:selectid}, function(result){ $("#fname").val(); //again using post method here get lastname $.post("one.php", {selectid:selectid}, function(result){ $("#lname").val(); }); }); }); }); </code></pre> <p></p> <p>retreive.php</p> <pre><code>&lt;?php //for firstname if( isset($_POST['selectid']) ){ //using this selectid i'm getting firstname echo $firstname; exit(); } //again for last name if( isset($_POST['selectid']) ){ //using this selectid i'm getting firstname echo $lastname; exit(); } ?&gt; </code></pre> <p>Finally this procedure auto filling the form fields i.e; firstname and lastname. I know this is foolish and time taken procedure. I've heard that this work done easily and no need to make our php bare all that burden with using the concept of JSON. I have tried to understand but couldn't. I hope you guys can understand the problem i'm facing, hoping for a solution. Thanks in advance! </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.
