Good day,

Currently I making a theme for I submit to WordPress theme. Again I have a little problem.

I’m using “Option Framework” plugin for create a simple theme option panel.

I have a problem when I create a multicheck box for category. I’m using this code in options.php

$options[] = array(
		'name' => __( 'Select Category : ', 'theme-textdomain' ),
		'desc' => __( 'Please select category for featured images 1 big image & 3 small images.', 'theme-textdomain' ),
		'id' => 'pt_featured_image1x3',
		'std' => '',
		'type' => 'multicheck',
		'options' => $options_categories
	);

I print using this code:

<?php $multicheck = of_get_option( 'pt_featured_image1x3'); ?>
<?php print_r($multicheck); ?>

The multicheck box output for category like this:

Array ( [1] => 1
         [3] => 1
         [7] => 1 )

I’m using this code to load the output:
<?php query_posts("cat="); ?>

How to make the code load like this:
<?php query_posts("cat=1,3,7"); ?>

Can someone help me, please!
