pass array value to a tag?

Hi, Cheaphotels. Since it appears you’re wanting to write your own add-on, I’ve moved this topic to the Development forum for additional community support.

No, you will need to serialize it some way. Try something like this.

{exp:mytag:subtag myparameter="<?php echo serialize($data_array); ?>"} 

    public function subtag() 
    {    
            $myparameter = (($myparameter = $this->EE->TMPL->fetch_param('myparameter', FALSE)) !== FALSE) ? @unserialize($myparameter) : FALSE;

            if ($myparameter !== FALSE AND is_array($myparameter)) 
            {
                // should be an array
            }
    }

tried serializing it. the array is broken. im making a plugin that preferably uses an array as input to process data.

code on template:

<?php
    $myarray = array(
            'rere' => 'dasdad',
            'lala' => 'dsdsd'
        );
?>
{exp:mytag:mymethod data_array="<?php echo serialize($myarray); ?>"}

echo echoed, myarray returns

a🔢{s:4:"rere";s:6:"dasdad";s:4:"lala";s:5:"dsdsd";}

code inside the plugin:

$data_array = $this->EE->TMPL->fetch_param('data_array');
print_r ($data_array);

returns a🔢{s:4:

tried using stripslashes. same thing, the array is broken. any ideas?

Here is another untested attemp:

{exp:mytag:subtag myparameter="<?php echo http_build_query($data_array); ?>"} 

        public function subtag() 
        {    
               $myparameter = $this->EE->TMPL->fetch_param('myparameter', FALSE);
                    parse_str($myparameter, $myarray);

                if (is_array($myarray)) 
                {
                    // should be an array
                }
        }

If that does not work you can always take the approach of getting the data in by another means besides a parameter. Take a look at http://ellislab.com/expressionengine/user-guide/development/usage/session.html#cache

thanks for the help, i figured it out

here goes

{exp:mytag:subtag  data_array="<?php echo urlencode(serialize($data_array)); ?>" }

to access it

$data_array = $this->EE->TMPL->fetch_param('data_array');
$data_array = unserialize(urldecode($data_array));

it seems that the problem is on the double quotes and curly brackets. CHEERS!
