display a error message with vanilla style

naquadaq

Hello,

I have written a SSO plugin and I want to display an error message with the vanilla style with the current theme. How can I do it?

x00

what type of error?

validation, notfound, denied, etc

It is a LTI plugin so they will be messages when a external application passes on the request information to my plugin. This plugin handles authentication a validation of the information received One of the messages p.e, is 'LTI context not available but needed. Proceess aborted' In fact, I think it doesn't matter the type of message. In general I would like to display a personalized message. Now I'm using echo and exit and redirect.

When I interpret the text from your reply to x00, I would say the errortype would be 'validation'. Let's see if Garden has a special errortype for that. Please add a Wiki page when you've found what you're looking for, explaining how to use, etc. :-)

Well it matter in terms of style, status codes etc. Whether true error, just relaying information.

if you just want a bonk/debug message then use

throw new ErrorException('Error Message.');

A useful method that I have used for permission errors is

$Message = T('You do not have permission to bla, bla, bla');
Gdn::Locale()->SetTranslation('PermissionErrorMessage',$Message));
throw new Exception($Message,401);

However there isn't a general error message page other than Bonk, and debug mode (which isn't ideal to show) If you include a view like so, it will display roughly equivalent.

<div class="SplashInfo">
   <h1><?php echo T('Error Message Title'); ?></h1>
   <p><?php echo T('Error Message'); ?></p>
</div>

If you want those inline red validation messages, a bit like flash

<div class="Messages Errors">
<ul>
    <li><?php echo T('Error Message'); ?></li>
</ul>
</div>

You can also use inform messages for more low key notification.

Eventually, I have used the PermissionErrorMessage. For one case, which displayed more information, I have used a simple echo because I wanted to add more views to the plugin.

Thank you for your help.
