    <p>I am trying to study <code>class.openid.php</code> because it is simpler and smaller than <a href="http://code.google.com/p/lightopenid/" rel="nofollow"><br> lightopenid</a>. for my purposes 200 lines do matter. But <code>class.openid.php</code> does not work with google openID <code>https://www.google.com/accounts/o8/id</code>, prints to me such error:</p> <pre><code>ERROR CODE: OPENID_NOSERVERSFOUND ERROR DESCRIPTION: Cannot find OpenID Server TAG on Identity page. </code></pre> <p>is it possible to make class.openid.php (any version) work with google openID and how to do such thing?</p> <p><code>class.openid.php</code> can be taken <a href="http://www.phpclasses.org/package/3290-PHP-Authenticate-users-with-OpenID-single-sign-on.html" rel="nofollow">here</a> but it did not worked for me out of the box so I had to find all <code>&lt;?</code> and replace tham with <code>&lt;?php</code> in case someone would like to see code I've got:</p> <p>html interface page:</p> <pre><code>&lt;?php require('class.openid.v3.php'); if ($_POST['openid_action'] == "login"){ // Get identity from user and redirect browser to OpenID Server $openid = new SimpleOpenID; $openid-&gt;SetIdentity($_POST['openid_url']); $openid-&gt;SetTrustRoot('http://' . $_SERVER["HTTP_HOST"]); $openid-&gt;SetRequiredFields(array('email','fullname')); $openid-&gt;SetOptionalFields(array('dob','gender','postcode','country','language','timezone')); if ($openid-&gt;GetOpenIDServer()){ $openid-&gt;SetApprovedURL('http://' . $_SERVER["HTTP_HOST"] . $_SERVER["PATH_INFO"]); // Send Response from OpenID server to this script $openid-&gt;Redirect(); // This will redirect user to OpenID Server }else{ $error = $openid-&gt;GetError(); echo "ERROR CODE: " . $error['code'] .

    1. COThe question can be generally answered with **Yes** because you can extend the class and add the missing functionality. But I think that is not what you ask for, I think you would prefer the download link of the new version of the class that has everything you're looking for, right?

    2. COI really don't think that these 200 lines of code do matter for you. Nevertheless, if you want to support OpenID 2.0 and attribute exchange, you'll have to use another library. And just to prove that line count doesn't matter, I've removed some code (half of which were comments, that the class in question noticeably lacks) in lightopenid to make it smaller than the class you use: http://pastebin.com/fE8qT3kW. It still supports both versions of OpenID, although it lacks support for retrieving attributes. So in summary, LightOpenID is neither more complicated, nor bloated.

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).
