Body
<p>When you are assigning the _SESSION url, you will need to use the posted variable to assign the string.</p> <pre><code>$_SESSION['url'] = $_GET['url']; </code></pre> <p>To do the opposite, and have the textbox show the value of the session, you would:</p> <pre><code>echo "<input type='text' id='starurl' value='" . htmlspecialchars($_SESSION['url']) . "'/>"; </code></pre> <p>It is important to note that if you want the text box to actually <em>do</em> something, you will need to have the input box wrapped around a form tag.</p> <p>The <code><form></code> tag tells the browser where the form starts and ends. You can add all kinds of HTML tags between the <code><form></code> and <code></form></code> tags. <a href="http://www.echoecho.com/htmlforms03.htm%5C" rel="nofollow noreferrer">(thanks echoecho!)</a></p> <p>If you are working RESTfully, GET should be used for requests where you are only getting data, and POST should be used for requests where you are making something happen.</p> <p>Some examples:</p> <ul> <li>GET the page showing a particular SO question</li> <li>POST a comment</li> <li>Click the "Add to cart" button and send a POST request.</li> </ul> <p>(<a href="https://stackoverflow.com/a/3477384/2143004">Thanks Skilldrick!</a>)</p> <p>The form & PHP file would look like this:</p> <pre><code><?php session_start(); if (isset($_POST['url']) { $_SESSION['url'] = $_POST['url']; } echo '<form action="POST" method="?">'; echo "<input type='text' id='starurl' value='" . htmlspecialchars($_SESSION['url']) . "'/>"; echo '</form>'; </code></pre> <p>You will notice when the form is updated, the session updates too. When you close your browser and open it again, you will see you old contents on the input box. (Press "enter" to save the input box without a submit button).</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.
