Array from callback to template

[localhost8080]

Hello, dear friends of this nice software.

Something is getting really lame here with v1.4:

I need to receive data from a callback function.

Within my method, I fill an array with data. before returning my array, I write it into my logfile to get sure the data gets populated.

Output in my logfile:

2014-12-27 18:22:03 ADDIDTIONALDATA: Array
(
    [key_1] => 01.01.2015
    [key_2] => error_successful
    [key_3] => bugware
)

Then, in my template, on

{xen:helper dump, {$additional_data}}

I receive

string(23) "
Array
"

looks like my brave array has been casted to a string? wtf!

and I can't access data with

{$additional_data.key_1}

which has been defined earlier:

<xen:set var="$additional_data">
                           <xen:callback class="Bugware_TemplateTools_ThreadHelper" method="getAdditionalData" params="{xen:array 'custom_fields={$thread.custom_fields}'}" />
                        </xen:set>

Any ideas? I'm really sick of wasting time with absolutely basic functions like array output within a template

Thank you.

How have you made the array param available to the template?

It might be better if you post the relevant segment of PHP code.

Hello Brogan,

here is the code:

public static function getAdditionalData(){
    $params = func_get_arg(1);
    $custom_fields = unserialize($params['custom_fields']);

    $additional_data = array();

    if(array_key_exists('key_1', $custom_fields)){
        $additional_data['key_1'] = $custom_fields['key_1'];
    }

    if(array_key_exists('key_2', $custom_fields)){
        $additional_data['key_2'] = $custom_fields['key_2'];
    }

    if(array_key_exists('key_3', $custom_fields)){
        $additional_data['key_3'] = $custom_fields['key_3'];
    }

    if(array_key_exists('key_7', $custom_fields)){
        $additional_data['key_7'] = $custom_fields['key_7'];
    }

    XenForo_Helper_File::log('bugware', 'ADDIDTIONALDATA: ' . print_r($additional_data, true), true);

    return $additional_data;
}

Thank you.

so what about my nice array now?

 

[localhost8080]

simple questions, big problems. by searching through the great documentation I fond this

Note on <xen:set>: You can only set a scalar (string, integer etc.); complex variables (arrays etc.) can't be set in this way.

so how do I set "compley" veriables like arrays?

Since XF 1.2:
<xen:set var="$var" value="{xen:array 'a=b', 'c=d'}" />

I have this one, as I get an array from my callback method. but it doesnt work...

<xen:set var="$additional_data">
                           <xen:callback class="Bugware_TemplateTools_ThreadHelper" method="getAdditionalData" params="{xen:array 'custom_fields={$thread.custom_fields}'}" />
                        </xen:set>

Looks like you will have to do things a little differently in order to achieve what you want.
I'm not sure what your end result is within the template but why not use the PHP function to save your custom fields and then return HTML created using your array values.

What do you use $additional_data for after you have set it? Might be relevant.

I receive an array and I want to check if keys are set to display some values from additional data...

Bear in mind a callback tag can return a template with view parameters which support arrays, e.g.

        $viewParams = array(
            'additional_data' => $additional_data
        );

        return $template->create('your_template_name', $viewParams);

That might help.
