Custom Error v0.1

By Byrne Reese
Posted July 2, 2010, in Developer.


The Custom Error plugin for Movable Type and Melody installs a global system template called "Custom System Error" which provides admins with the ability to override the default system error template generated by, well, the system. Duh.


To install this plugin follow the instructions found here:


To use the plugin, simply install it and run the upgrade process you are prompted with. This will automatically install the error template you can customize.


Inside the error template, this plugin gives you access to a number of parameters which might be of use to you. All of these paramters can be accessed like any other template variable. For example:

<$mt:var name="error"$>
  • error - the error message generated by the system
  • app_class - the class of the calling application. Values can be:
    • MT::App::CMS
    • MT::App::Comments
  • debug_mode - a boolean value which is true if debug mode is currently enabled

I haven’t tried the tutu before, is it another Movable Type plugin? I really like this one though since it allows me to take control of the different errors when they occur and show what I want. Not that the default ones aren’t good. But it allows me to have more control over my blog. And that is why I like Movable Type so much. It lets me control how my custom wedding stamps site behaves which is important to me as well as my users.

It is the issue with the instrument that is being used. Even in the event that it is another instrument, it should be calibrated before playing out any sorts of test. It can be dodged if lab is free from any type of harms including condition the instrument is kept in Irregular blunders are chiefly because of wrong treatment of the test strategy. That is the reason to maintain a strategic distance from irregular mistakes more than one trial is performed.
