ASSUMPTIONS

The code of this plugin assumes that user message template (you can find it by going Control Panel Home >  Admin >  Specialty Templates >  User Message Template) in cases of successful login and successful logout outputs HTML page having <title> element containing text “Login” and in case of some error outputs HTML page having <title> element containing text “Error”. Also this plugin assumes that user message template outputs error message which is contained inside <li> tag and success message which is contained inside <p> tag.

USAGE

USAGE WITH SSL

Using this add-on you can create secure login form. To create it you need to make 2 changes in the code above.

First, you need to force the page to be loaded over SSL. You can achieve this by installing free DM Force SSL plugin
available at http://devot-ee.com/add-ons/dm-force-ssl and adding the tag

{exp:dm_force_ssl:force}

on top of the template.

Second, you need to change the URL scheme of the login form from “http” to “https”. You can achieve this by installing free
Find and Replace Plus plugin available at http://devot-ee.com/add-ons/find-and-replace-plus and wrapping the tag exp:member:login_form
with

{exp:replace_plus find='action="http:' replace='action="https:'}
{exp:member:login_form id="login_form"}

Login form code

{/exp:member:login_form}
{/exp:replace_plus}

That’s it! You now have secure login form.
