    <p>I have a simple html form with a single field that submits to download.php which validates the form and finally sends me back an email with the user input. So far, everything works great - but I would like the error messages and thank you message to display inside the original html form, not on a new page (as is happening now).</p> <p>Can you tell me how to keep myform.html visible after the submit button is clicked, and load the error and thank you messages inside the "notification" div?</p> <p>BTW, just in case it's relevant, myform.html is dynamically displayed inside a on index.html using jQuery .load().</p> <p>Thanks for your help!</p> <p>myform.html</p> <pre><code>&lt;html&gt; &lt;head&gt;...&lt;/head&gt; &lt;body&gt; &lt;div id="notification"&gt;&lt;/div&gt; &lt;!-- want to load errors and thank you, here --&gt; &lt;form id="downloadForm" method="post" action="_php/download.php"&gt; &lt;label for="biz_email"&gt;Business Email:&lt;/label&gt;&lt;input type="text" name="biz_email"&gt; &lt;div id="submit" class="submit_button"&gt;&lt;/div&gt; &lt;!-- FYI submit function called in separate jQuery file --&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>download.php</p> <pre><code>&lt;?php if(isset($_POST['biz_email'])) { $email_to = "foo@bar.com"; //my email $email_subject = "form submission"; $email_from ="form test"; $biz_email = $_POST['biz_email']; $error_message = ""; // validation ... //error code function died($error) { echo "There are errors in your submission:&lt;br /&gt;&lt;br /&gt;"; echo $error."&lt;br /&gt;&lt;br /&gt;"; echo "Please go back and fix these errors.&lt;br /&gt;&lt;br /&gt;"; die(); } //email message (sent back to me) $email_message = "Form details below.\n\n"; function clean_string($string) { $bad = array("content-type","bcc:","to:","cc:","href"); return str_replace($bad,"",$string); } $email_message .= "Email: ".clean_string($biz_email)."\n"; // create email headers $headers = 'From: '.$biz_email."\r\n". 'Reply-To: '.$biz_email."\r\n" . 'X-Mailer: PHP/' . phpversion(); @mail($email_to, $email_subject, $email_message, $headers); ?&gt; &lt;!-- thank you message --&gt; Success! &lt;?php } ?&gt; </code></pre>

    1. COTwo ways to accomplish that - 1) Post the page to itself and do the error checking at the beginning of the script; 2) Use AJAX (i.e., jQuery's validation plugin) to test all the data before you POST it to the new page. http://jqueryvalidation.org/

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
