Body
<p>I have some code that is working but I would like to add two things to it that I don't know how to do. </p> <p>It's a simple form that send data to my database (jQuery / AJAX) and then display the data on the web page. </p> <p>Problem 1:<br> When I refresh the page, all the message are displayed on separate lines (which is what I want) but when I add new messages and click on the submit button, all the new messages get displayed on the same line. Is there a way I could put a <br /> or force the comment to be displayed on a new line ?</p> <p>Problem 2: When I refresh index.php, only 10 messages are displayed and that's good because I used a "LIMIT 0, 10" on my query. When I type a new message and click on the button to submit to the database, the message list is "updating" by itself but ADD a new message to the list instead of replacing the 10th message by the new one.</p> <p>index.php </p> <pre><code><html> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <head> <title>Untitled Document</title> <script src="jquery-1.10.2.min.js" type="text/javascript"></script> <script type="text/javascript"> function sendMessage() { $.ajax({ url: "ajax.php", type: "POST", data: {comment : document.getElementById('message').value}, dataType:"html", success: function(data, textStatus, xhr) { $("#output").append(document.getElementById('message').value); document.getElementById('message').value = ""; } }); } </script> </head> <body> <form name="addComment"> <input type="text" name="message" id="message" /> <input type="button" name="submitBtn" id="submitBtn" value="Envoyer" onclick="sendMessage();" /> </form> <div id="output"> </div> <?php include("class.php"); $object1 = new Shootbox(); try { $object1->showMessage(); } catch(Exception $e) { echo "Exception : ".$e->getMessage(); } ?> </body> </html> </code></pre> <p>ajax.php </p> <pre><code><?php mysql_connect("localhost", "root", "root"); mysql_select_db("PFtest"); $message = $_POST['comment']; if (strlen($message) > 0) { mysql_query("INSERT INTO comments VALUES ('NULL', '".$_POST['comment']."', CURRENT_TIMESTAMP)"); echo "Message enregistré !"; } elseif(strlen($message) < 0) { echo "Nothing here"; } ?> </code></pre> <p>class.php </p> <pre><code><?php class Shootbox { public function showMessage() { mysql_connect("localhost", "root", "root"); mysql_select_db("PFtest"); $query = mysql_query("SELECT * FROM comments ORDER BY date DESC LIMIT 0 , 10"); if(mysql_num_rows ($query)>0){ while($result = mysql_fetch_object($query)){ echo $result->message."<br />"; } } else{ throw new Exception("Aucune donnée dans la base de données"); } } } ?> </code></pre>

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.
