Setting included elements dynamically

[nilshoerrmann]

This is question for @brendo:

For the inline output of associated entries I'll add a few settings the Data Source file:

    public $dsParamINCLUDEDASSOCIATIONS = array(
        'festival' => array(
            'section_id' => 8,
            'field_id' => 58,
            'elements' => array(
                'anfang',
                'ende'
            )
        )
    );

This information is used to dynamically create a custom Data Source to fetch the needed entries, see https://github.com/hananils/association_output/blob/master/extension.driver.php#L67-L75:

    private function fetchAssociatedEntries($settings, $entry_ids = array())
    {
        $datasource = DatasourceManager::create('associations');
        $datasource->dsParamSOURCE = $settings['section_id'];
        $datasource->dsParamFILTERS['system:id'] = implode($entry_ids, ', ');
        $datasource->dsParamINCLUDEDELEMENTS = $settings['elements'];

        return $datasource->execute();
    }

The problem is that $datasource->dsParamINCLUDEDELEMENTS = $settings['elements']; doesn't have any effect. If I print $datasource before execution, I'll see that all settings are in place correctly, still the Data Source doesn't return any elements. If I set the same elements in the dummy Data Source file data.associations.php directly, it works though.

Any idea what's going on here, what I'm doing wrong here?

[brendo]

Hmm, can you verify what getSource is returning? I'm wondering if this function is returning nothing.

What do I have to do to get this environment setup locally? Just the Symphony integration branch?

[nilshoerrmann]

Yes, integration + this extension.

You'll have to add and adjust the additional setting to a DS with an associative field in the output. I've used a select box with dynamic values for testing.

[nilshoerrmann]

I just pushed a few changes to the repo: associations can now be included in the DS editor directly.

The issue mentioned above still exists. If I print the Data Source before execution, I get the following output (showing the included elements correctly:

datasourceassociations Object
(
    [dsParamROOTELEMENT] => associations
    [dsParamPAGINATERESULTS] => no
    [dsParamSTARTPAGE] => 1
    [dsParamREDIRECTONEMPTY] => no
    [dsParamSORT] => system:id
    [dsParamASSOCIATEDENTRYCOUNTS] => no
    [dsParamINCLUDEDELEMENTS] => Array
        (
            [0] => festivaljahr
            [1] => anfang
            [2] => ende
        )

    [dsParamSOURCE] => 2
    [_env:protected] => Array
        (
        )

    [_param_output_only:protected] => 
    [_dependencies:protected] => Array
        (
        )

    [_force_empty_result:protected] => 
    [_negate_result:protected] => 
    [dsParamFILTERS] => Array
        (
            [system:id] => 660, 624
        )

)

But the resulting XML tree looks like this:

XMLElement Object
(
    [_name:XMLElement:private] => associations
    [_value:XMLElement:private] => Array
        (
        )

It's outputting the correct entries, only the fields are missing. Ideas?

[nilshoerrmann]

Doh! I seem to have stored the wrong field ids …
