    <p>I have a client which has wish that url referer gets send along contact email. This already worked and suddenly stopped over night, with no clues what's the problem.</p> <p>The platform is, sadly, Wordpress.</p> <p>This in the header.php:</p> <pre><code>if(!session_id()){ //session_destroy(); session_start(); } if(!isset($_SESSION['referer'])){ if(isset($_SERVER['HTTP_REFERER'])&amp;&amp;!empty($_SERVER['HTTP_REFERER'])){ $ref=strtolower($_SERVER['HTTP_REFERER']); if(strpos($ref,'facebook')!==false){$_SESSION['referer']="Facebook";$_SESSION['refererURL']=$ref;} elseif(strpos($ref,'google')!==false){$_SESSION['referer']="Google";$_SESSION['refererURL']=$ref;} else{$_SESSION['referer']="Web";$_SESSION['refererURL']=$ref;} } } </code></pre> <p>and this is in my contact-us.php:</p> <pre><code>$referer=trim($_SESSION['referer']); $refererURL=trim($_SESSION['refererURL']); </code></pre> <p>According to the code, I should be getting three different referers depending on where user has come from, but I'm constantly getting "Web" aka. no referer specified.</p> <p>What am I doing wrong?</p> <p>And to clarify:</p> <ul> <li><code>session_start()</code> hasn't been run before header.php,</li> <li><code>add_action( 'init', 'session_start' );</code> doesn't work,</li> <li>no errors produced, it just saves the wrong referer,</li> <li>this exact code has worked 1 day ago, now it doesn't and as far as I know, no changes has been made!</li> </ul> <p><strong>EDIT:</strong> I have moved everything to <code>$_COOKIE</code> variables and removed entry from xmlrpc.php <code>$_COOKIE = array();</code> and it's working. It appears that wordpress has some strange logic when it comes to <code>$_SESSION</code>.</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.

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).
