Display multiple checkboxes array

[zazu]

Hi there guys,

I've made some new checkbox fields in my wordpress template using Meta box. Now i want to display those selected checkboxes in the forntend, but it will display only the first checkbox that i've checked, not the other ones. The problem seems to by the array functions that displays only the first checkbox. I'll put bellow the codes that i've been using:

 

This is the code from the meta-box-config.php

    // General //////////////////////////////////////////////////////////////////////////////////////
        array(
            'name'      => 'Genearal',
            'id'        => "{$prefix}utilitati_general",
            'clone'     => false,
            'type'      => 'checkbox_list',
            'options'   => array(
                'Curent Electric' => __('Curent electric','locality'), 
                'Telefon' => __('Telefon','locality'),
                'Apa' => __('Apa','locality'),
                'Gaz' => __('Gaz','locality'),
                'Cablu TV' => __('Cablu TV','locality'),
                'Canalizare' => __('Canalizare','locality')
            ),
            'std'       => false
        ),

This is the code from the frontpage 

// General //////////////////////////////////////////////////////////////////////////////////////
$locality_utilitati_general = get_post_meta($post->ID, 'locality_utilitati_general', true);
if(!empty($locality_utilitati_general))
  {
    ?>
    <?php _e('General: ','locality'); ?><?php echo implode(',', $_POST['locality_utilitati_general']); ?>
    <?php
  }

From http://codex.wordpress.org/Function_Reference/get_post_meta you'll see that you're passing true to the third parameter which states:

(boolean) (optional) If set to true then the function will return a single result, as a string.

 

Without a wordpress to test on, i would loop over whatever is returned when that third parameter is set to false and see what is returned. I would expect the boxes you've checked to be returned.

 

However if everything was returned, i would expect some kind of flag that lets you know it was checked.

Hi thx for help, i've solved my problem. The modified code is below:

// General //////////////////////////////////////////////////////////////////////////////////////
$locality_utilitati_general = get_post_meta($post->ID, 'locality_utilitati_general', 0);
if(!empty($locality_utilitati_general))
  {
    ?> 
    <?php _e('General: ','locality'); ?><?php echo implode(", ", $locality_utilitati_general); ?>
    <?php
  }
