    <p>I have an AJAX login system - all the form data is validated using PHP and if there is a match for the username and password it sets certain cookies.</p> <p>I am aware that cookies need to be set before ANYTHING else, but how is this possible with the model I am using. I want to keep the whole login refresh-less.</p> <p>I am getting the error: "Cannot modify header information - headers already sent by....."</p> <p>Does anyone have any advice?</p> <p>Thanks</p> <p>EDIT: the form is validated using an IF statement then if the conditions are met the cookies are set in there</p> <p>The code: alllll of it</p> <pre><code>&lt;?php session_start(); include "connect.php"; if ($_POST) { $loginuser = mysql_escape_string($_POST['loginuser']); $loginpass = mysql_escape_string($_POST['loginpass']); $rememberme = mysql_escape_string($_POST['rememberme']); if ($rememberme = 1) { $time = time()+60*60*24*365; } else { $time = time()+3600; } $salt = changedsalt"; $hashed_password = sha1($loginpass).sha1($salt); $getUser_sql = "SELECT * FROM acts WHERE username = '$loginuser' AND hashed_password = '$hashed_password'"; $getUser = mysql_query($getUser_sql); $getUser_RecordCount = mysql_num_rows($getUser); if($getUser_RecordCount == 1) { $rowLogin = mysql_fetch_array($getUser); $user_id = $rowLogin['id']; $emailad = $rowLogin['email']; $activated = $rowLogin['activated']; if ($activated == 1) { $hash = "changedthistoo"; $randstring = rand(5, 10); $code = sha1($hash . $randstring); mysql_query("UPDATE `acts` SET `key` = '$code' WHERE `id` = '$user_id' AND `email` = '$emailad'"); setcookie('AHkey', $code, $time, '/'); setcookie('AHid', $user_id, $time, '/'); setcookie('AHem', $emailad, $time, '/'); setcookie('AHty', 'acts', $time, '/'); setcookie('AHtr', 1, time()+3600, '/'); $data['success'] = true; $data['message'] = "Act Login - Activated"; $data['message'] = $code; echo json_encode($data); exit; } else { $data['success'] = false; $data['message'] = "Act Login - Not Activated"; echo json_encode($data); exit; } } elseif ($getUser_RecordCount == 0) { $getUser_sqlp = "SELECT * FROM promoter WHERE username = '$loginuser' AND hashed_password = '$hashed_password'"; $getUserp = mysql_query($getUser_sqlp); $getUser_RecordCountp = mysql_num_rows($getUserp); $rowLogin = mysql_fetch_array($getUserp); $user_id = $rowLogin['id']; $emailad = $rowLogin['email']; $activated = $rowLogin['activated']; if($getUser_RecordCountp == 1) { if ($activated == 1) { //generate random string $hash = "49ebva09afbh"; $randstring = rand(5, 10); $code = sha1($hash . $randstring); mysql_query("UPDATE `promter` SET `key` = '$code' WHERE `id` = '$user_id' AND `email` = '$emailad'"); setcookie('AHkey', $code, $time, '/'); setcookie('AHid', $user_id, $time, '/'); setcookie('AHem', $emailad, $time, '/'); setcookie('AHty', 'promoter', $time, '/'); setcookie('AHtr', 1, time()+3600, '/'); $data['success'] = true; $data['message'] = "Act Login - Activated"; $data['message'] = $code; echo json_encode($data); exit; } else { $data['success'] = false; $data['message'] = "Promoter Login - Not Activated"; echo json_encode($data); exit; } } else { $data['success'] = false; $data['message'] = "Wrong Username or Password"; } } echo json_encode($data); } ?&gt; </code></pre>

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).
