andRelatedTo with a condition

[shifuma]

I'm looking to query for entries with relations like this:

{% set entries = craft.entries()
  .andRelatedTo({
    sourceElement: category,
    field: 'category',
    myFieldHandle: 'myFieldValue'
  })
  .all() %}

So basically, only get the relations where another field in the Matrix entry has a value of myFieldValue. I hope that makes sense.

Is that possible as is? If not, could something like that be made possible?

Actually maybe this could be an extension of my other request: #15790

If the opposite of that was added (for example a nested or nestedId param) I could instead do:

{% set nestedEntryIds = craft.entries().field('matrixField').myFieldHandle('myFieldValue').ids() %}
{% set entries = craft.entries().section('mySection').nestedId(nestedEntryIds).all() %}

Can you clarify what you’re trying to do?

I'm trying to filter entries based on what is inside a Matrix field. Specifically, based on the entry type.

Entry 1
- Matrix field has entries with entry type 1 & 2

Entry 2
- Matrix field has entries with entry type 2

Entry 3
- Matrix field has entries with entry type 2 & 3

So I want to query for all entries with entry type 1 & 3 in the Matrix field.

Gotcha. The only current way to do that is by getting the IDs of the nested entries first, and then passing them to the Matrix field’s param on the parent entry query:

{% set nestedIds = craft.entries()
  .field('myMatrixField')
  .type(['type1Handle', 'type3Handle'])
  .ids() %}

{% set entries = craft.entries()
  .section('mySection')
  .myMatrixField(nestedIds)
  .all() %}
