Install Extension Help


New here.

I’m not 100% sure of how composer and extensions all work together.

I’ve managed to get one extension to work - mpdf/mpdf after watching this https: // watch?v=L8L_ZEns_xw YouTube video. (link split up as first time poster cannot put in links)

In there after the extension is installed using composer an entry is made into autoload_namespace.php.

I have this extension working.

Now, however, everytime I try install a kartik-v extension I get the "Class not found" error.

I add an entry into the autoload_namespace.php , as above, but it still doesn’t work.

I have the use statement:

use kartik\export\ExportMenu;

Anyone able to point me in the right direction to get this working please?
