Installing the Modern Contact plugin in DokuWiki

Installing a Contact form on your DokuWiki site can be somewhat complex. DokuWiki does not have any contact form capability built into their software. In order for you to get a contact form on your DokuWiki site, you will need to use a plugin.  This tutorial will explain how to use the Modern Contact plugin for DokuWiki.

Once you have the Modern Contact plugin installed, you can add the code to your wiki page that is designed to store your Contact form. The following are example codes you can use in your wiki Contact page.

{{contact>subj=Contact the Developer}}}
{{contact>to=Admin|subj=Contact the Developer}}

The table below has a brief description of the attributes available for the contact form code.

    Before the contact form will display on your page, you will need to fix the code in the plugin. The following will explain how to fix the plugin code.

Fixing the Modern Contact plugin code

To fix the code, we will need to “find and replace” a specific code in one of the files of the plugin. This is because the plugin developers have not created a fix for a bug in the plugin.

Important! When using find and replace, its important to make sure you typed the words correctly and that you have a backup of the plugin. Find and replace cannot be undone so be careful.

  1. Login into your cPanel.
  2. Go to the File Manager. Select your DokuWiki installation directory and click go.
