    <p>i am trying to add and delete records(games) from my database using jquery and ajax. i am still a junior software engineer and learning the basics of web development but i have this task to accomplish and unsure what i am missing for it to work.</p> <p>i have 5 columns from my database and the ID is hidden with auto increment. </p> <p>my question is what is broken in the code that is not letting me add or delete a game and reflect it on the database???</p> <p>this is my main file with the calls to delete and add games. </p> <pre><code> &lt;script type = "text/javaScript" src ="http://code.jquery.com/jquery- latest.js""&gt;&lt;/script&gt; &lt;script type = "text/javascript"&gt; $(document).ready(function(){ $("add games").Submit(function() $("#add").load("add.php"); { var id = $("#ID").val(); var name = $("#name").val(); var type = $("#type").val(); var rating = $("#score").val(); var release = $("Yreleased").val(); var dataString = 'ID=' + id 'name='+ name + '&amp;username=' + type + '&amp;password=' + rating + '&amp;gender=' + release; if (id =='' || name == '' || type == '' || rating == '' || release == '') { alert("please enter some valid data for your game entry"); } else $.ajax({ type: "POST", url: "add.php", data: dataString, success: function(){ $('.success').fadeIn(200).show(); $('.error').fadeOut(200).hide(); } }); } return false; }); }); &lt;/script&gt; &lt;body&gt; &lt;?php include("dbconfig.php"); $sql = "SELECT * FROM games"; $result = mysql_query($sql); while ($record = mysql_fetch_array($result)){ echo "&lt;/br&gt; Game ID: " .$record['ID']. "&lt;/br&gt; Game Name: " .$record['Name']. "&lt;br /&gt; Game Type: ".$record['Type']. "&lt;br /&gt; Rating: ".$record['Rating']."&lt;br /&gt; Year Released: ".$record['Release Year']."&lt;br /&gt; &lt;br /&gt;" ?&gt; &lt;a href="#" id="&lt;?php echo $record["ID"]; ?&gt;" class="deletebutton"&gt;&lt;img src="trash.png" alt="delete"/&gt;&lt;/a&gt; &lt;?php } ?&gt; &lt;form name="add" id ="add" action="add.php" method="post"&gt; &lt;input class ="gameID" type="hidden" id="ID" value = " ' .$record['ID'] .

"; ?&gt; </code></pre> <p>and last my dbconfig</p> <pre><code> &lt;?php $user_name = "root"; $password = ""; $database = "gamebook"; $server = "localhost"; $bd = mysql_connect($server, $user_name, $password) or die ('I cannot connect to the database because:' . mysql_error()); mysql_select_db($database); ?&gt; </code></pre> <p>this is the first time every i post a question and ask, so if i did something unacceptable or that should have been done otherwise, i would appreciate the tips, help, links, or if someone can help me on how to fix my issue. i can read from the database, but not add or delete from it dynamically.</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.
