I have a collection of users and I want to create a backend grid to show only some user depending on a filter.

For example I want to show all the users in my table whith age greater than 18.

I created a new collection and i added my filter to _initSelect method.

...

protected function _initSelect()

{

    parent::_initSelect();

    $this->addUsersFilter();



    return $this;

}

...

public function addUsersFilter()

{

    $this

        ->addFieldToFilter('age', ['gteq' => 18]);



    return $this;

}

...

Bt my grid keeps showing me the whole table content regardless my filter.

Does anyone knows how to filter a grid directly from its source collection?

Ok, I found it by myself. Posting here if it helps:

This kind of filter cannot be done at collection level, but only at data provider level.

So, if you have:

<virtualType name="MyModuleModelResourceModelGridItemsCollection"

             type="MagentoFrameworkViewElementUiComponentDataProviderSearchResult">

    <arguments>

        <argument name="mainTable" xsi:type="string">my_table</argument>

        <argument name="resourceModel"

                  xsi:type="string">MyModuleModelResourceModelItemsCollection</argument>

    </arguments>

</virtualType>

You can just point to your custom data provider instead of inheriting from MagentoFrameworkViewElementUiComponentDataProviderSearchResult.

Your XML becomes:

<virtualType name="MyModuleModelResourceModelGridItemsCollection"

             type="MyModuleUiComponentDataProviderSearchResultItems">

    <arguments>

        <argument name="mainTable" xsi:type="string">my_table</argument>

        <argument name="resourceModel"

                  xsi:type="string">MyModuleModelResourceModelItemsCollection</argument>

    </arguments>

</virtualType>

Now we are referring to MyModuleUiComponentDataProviderSearchResultItems instead of MagentoFrameworkViewElementUiComponentDataProviderSearchResult.

Now we have to create our new class:

<?php

namespace MyModuleUiComponentDataProviderSearchResult;



class Items extends MagentoFrameworkViewElementUiComponentDataProviderSearchResult

{

    protected function _initSelect()

    {

        parent::_initSelect();

        $this->addMyCustomFilter();



        return $this;

    }



    public function addMyCustomFilter()

    {

        $this

            ->addFieldToFilter('age', ['gteq' => 18])



        return $this;

    }

}

Hope it helps.

when I passing dynamic value from URL like:

 $nameURL = $_SERVER["REQUEST_URI"];

 ... do something with $nameURL and get value: $name = "myname"

 and code:

  $this->addFieldToFilter('name', ['eq' => $name]); // not working
