    <p>I'm currently trying to implement a feature to check if an email has already been taken when a first time user registers for my site. I'm trying to do this with AJAX and use the jQuery tooltip (http://flowplayer.org/tools/tooltip/) plugin to display the message if the e-mail has in fact been taken.</p> <p>I don't want to display any message if the e-mail is not taken and don't want the user to be aware of the fact that I'm checking their e-mail against the database, when they focus out of the e-mail input box. I only want to display a tooltip message if the e-mail has been taken and then make sure it dissapears if they provide a new unique e-mail address.</p> <p>Here is my code thus far: <strong>register.php (where the form is)</strong></p> <pre><code>&lt;div class="textboxfrm"&gt;&lt;span class="label"&gt;Email&lt;span style="color:#FF9000"&gt;* &lt;/span&gt; &lt;/span&gt;&lt;span class="left"&gt;&lt;/span&gt;&lt;span class="center"&gt;&lt;input class="required validate-email" id="email" name="email" type="text" style="width:230px;" maxlength="50" /&gt; &lt;/span&gt; &lt;div class="tooltip_email"&gt;&lt;/div&gt; &lt;/div&gt; </code></pre> <p><strong>register.js</strong> (loaded on document.ready)</p> <pre><code>jQuery("span.center").tooltip({ events: { span: 'dblclick, dblclick', input: 'blur, mouseout', }, effect: "slide", delay: 3000, onBeforeShow: function() { jQuery("#email").blur(function() { // when focus out email = jQuery('#email').attr('value'); if (email.length &gt; 1){ jQuery.ajax({ type: "GET", url: "checkusername.php", data: "email=" + email, success: function(data) { jQuery(".tooltip_email").html(data); } }); //end ajax call }//end if email &gt; 1 else { jQuery("span.center").tooltip.hide(); } //jQuery(".tooltip_email").hide(); });//end email blur //return false; } // end onBeforeShow function }); //end span.center tooltip </code></pre> <p>Finally, <strong>checkusername.php</strong> (where the database is accessed)</p> <pre><code>&lt;?php $email = $_GET['email']; // connection settings stored in file include("connectionParameters.php"); $connection = mysql_connect($host,$user,$pass) or die ("We're sorry, there seems to be an error. Please try again later."); mysql_select_db($database); $email = $_GET['email']; mysql_select_db("testdatabase", $con); $sql= sprintf("SELECT * FROM Users WHERE email='%s'", mysql_real_escape_string($email)); $result = mysql_query($sql); $row = mysql_fetch_array($result); $taken = $row['email']; if(mysql_num_rows($result) &gt; 0){ echo "&lt;p&gt;This email belongs to a registered user. Please provide a different email address, or visit &lt;a href='forgot_pass.php'&gt;this&lt;/a&gt; page to retrieve your password.&lt;/p&gt;"; } else if(mysql_num_rows($result) &lt; 1) { exit(); } mysql_close($con); ?&gt; </code></pre> <p>To make the question a little clearer, the checking of the email is working correctly and I'm seeing the message if an email is taken via the tooltip. However, I'm also seeing the tooltip with no message if I hover over "span.center" or if I change the email to a valid one or If the email is greater than 2 characters. My problem is that I don't want to see the tooltip box <strong>at all</strong> under any of those scenarios.</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.
