Hi There,
The company I work for is having a website developed using Opencart. I am a apprentice and my boss has asked me to create a "Hello World" module, where we can simply present text to users, I am new to Opencart so we are starting with something simple. I know that there is a module HTML for presenting text on the front end, but for the purposes of understanding modules, this is what my boss assigned me to do.
I have created files in the following directories:
/admin/language/en-gb/extension/module/helloworld.php
/admin/controller/extension/module/helloworld.php
/admin/view/template/extension/module/helloworld.twig
/catalog/controller/extension/module/helloworld.php
/catalog/view/theme/default/template/extension/modue/helloworld.twig
From the admin side, you can insert a header and text in a text field which would then be displayed the user once my helloworld module has been introduced to a layout. However, it is not updating / being shown on the front end after adding it to my home page layout.
It is inserting into the oc_module as it should and the module has been enabled. I have also cleared my browser history. I have also refreshed the Theme and SASS on the dashboard developer settings.
I know it will be something really obvious but as i am new to this i cannot seem to figure it out.
Thanks,
If you don't post code or files nobody will able to help you.

Backup and learn how to recover before you make any changes!
And remove both function (install, uninstall) from controller.

Still isn't showing on the front end
Also not seeing html defined in your controller.
Maybe you meant your twig to be?
Code: Select all
{% if html %}
<h2>{{ html }}</h2>
{% endif %}Code: Select all
{% if helloworld %}

Deactivate the module and then activate it again. Fill out some test content.
Then go back to design view where you want it to appear and ensure you are clicking the plus sign before saving.
Theme used? OC version?

You need to add that module to journal 3 layout.
Or switch to Default theme and see if work.
