    <p>I am having problems with my login process. I am using sessions and reloading so that I can have a single page site. On Chrome, this adds a ? so the end of the url (anytime the ? is present, login does not work). And on both Firefox and Chrome, the login-logout process only works once and then login stops working. I have an if statement on my index.php page that is essentially:</p> <pre><code>if($_SESSION["LoggedIn"] != true) { /*display login button*/ } else { /*display logout button*/ } </code></pre> <p>Then I set my scripts file:</p> <pre><code> $("#toolbarTitle-Login").click(function() { var loginEmail = $("#toolbarTextbox-Email").val(); var loginPassword = $("#toolbarTextbox-Password").val(); if (loginEmail != "") { $("#toolbarPleaseWait").text("Please wait..."); $.post( 'ajax/loginProcess.php', { 'email': loginEmail, 'password': loginPassword }, function (response) { window.location.reload(true); } ); } }); $("#toolbarTitleLoggedIn-Logout").click(function() { $("#toolbarPleaseWait").text("Logging out..."); $.post( 'ajax/logoutProcess.php', { }, function (response) { window.location.reload(true); } ); }); </code></pre> <p>Then my processing pages loginProcess.php:</p> <pre><code>&lt;?php session_start(); include "../incl/databaseConnection.php"; $email = $connection-&gt;real_escape_string($_POST["email"]); $password = $connection-&gt;real_escape_string(md5($_POST["password"])); $sql = "SELECT clientId FROM clients WHERE (studentEmail = '$email' AND studentPassword = '$password') OR (parentEmail = '$email' AND parentPassword = '$password');"; if (!$result = $connection-&gt;query($sql)) { die ('There was an error running the query [' . $connection-&gt;error . ']'); } $rows = $result-&gt;num_rows; $row = $result-&gt;fetch_assoc(); if ($rows == 1) { $_SESSION["loggedIn"] = true; $_SESSION["clientId"] = $row["clientId"]; } else if ($rows &gt; 1) { echo 'CHOOSE BETWEEN ACCOUNTS'; } else if ($rows == 0) { echo 'SHOW ERROR MESSAGE'; } $connection-&gt;close(); ?&gt; </code></pre> <p>Next logoutProcess.php:</p> <pre><code>&lt;?php session_start(); session_unset(); ?&gt; </code></pre>

    1. COWhy bother with the `$.ajax()` calls to login and logout if you are going to refresh the page with `window.location.reload()` in their success callbacks?

    3. COMy point is if the page needs to be reloaded anyway, there is no value to doing any ajax call or JavaScript. Just link a login or logout URL, where PHP handles the unset() and if necessary redirects back to the original URL (without anything like `?logout`)

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.

SQuiL has stopped working due to an internal error.

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