Create a custom type of filter based on the checkbox

Hi,

I am trying to create a custom filter type.
This would be a copy of the 'checkbox' filter with some differences in the display (hidden option values by default, unless you click on the 'category').

I don't know if it's possible, but I had started to try by following the documentation that explains how to use the overrides.
I've made some progress (creating the filter with this new type in the backend seems ok) and I have created these files :
\administrator\templates\atum\html\com_hikashop\administrator\classes\filter.override.php
\administrator\templates\atum\html\com_hikashop\administrator\types\filter.override.php

My question is about the override in the 'classes' folder:
I have tried these classes without result:
class hikashopFilterClassOverride extends hikashopClass {
class hikashopFilterClassOverride extends hikashopFilterClass {

1) I understand that the 'displayFilter()' function is used, but is it possible to override it?
Because whatever I do, I pass in the function defined here: (~l.382)
\administrator\components\com_hikashop\classes\filter.php

Other question:
In this file, we have the code (~l.384):

$classType = 'hikashop'.ucfirst($filter->filter_type).'Class';
$class = new $classType();
$html = $class->display($filter, $divName, $parent, $datas);

Hi,

I was able to make progress thanks to you.

I had misunderstood the documentation about the paths (especially the one containing the folder 'administrator' but for the frontend: templates/YOUR_TEMPLATE/html/com_hikashop/admnistrator/XXXX/yyy.override.php
Sorry about that.

By the way, I think there is a small mistake in the documentation (It says 'adminstrator' instead of 'administrator').

It seems to work fine except for one class (hikashopFilterTypeClassOverride)..
In the file : \administrator\templates\atum\html\com_hikashop\administrator\classes\filter.override.php

Indeed, I had a problem with this relationship: 'the class hikashopRadioClass extends from hikashopFilterTypeClass'

I managed to do what I wanted and understood a lot of things with your help.

Once again, big thanks to you !

Hi,

Sorry to bother you again with this (hopefully for the last time), but I tried to override the 'hikashopInStockCheckboxClass', to change the appearance of the 'in stock' filter, without success.

I wanted to override the 'display' function :

Hi,

Ok thanks, I understand better

To be sure I understand, in 'filter.php', only the 'hikashopFilterClass' class would be overridable?
Not the others, even if it's a class that directly 'extends' the 'hikashopClass' class, like the 'hikashopFilterTypeClass' class ?

Noted.

Thanks to you I have made progress and I think I am very close to the end.

EDIT : I think I have identified the last problem (in the spoiler): I need to find out how to override the addFilter() function of the 'hikashopFilterTypeClass' class. I will look for a solution.

EDIT2 : Problem solved ! Thank you for your help.

Boxed in red, my changes for the override.

Last question (hopefully):
I can't find where I need to make a change so that it only shows products in stock (when checked).

If I change my filter back to the default, the out of stock products are well hidden.
So I must be missing an override somewhere concerning the refreshing of the filters for my custom filter.

I overrided '/types/data_filter,' too (back and front).

Do you have any idea what I missed?

Hi,

It's me again, but I think I have a problem that is not related to what I did, but to the filters:
My filters work fine except for one category where when I change the value of a filter I get errors

Done, sorry.
Indeed, I should have started with that.

Hi,

With this latest version the problem seems to be gone.

Thank you !
