Wordpress theme options page query_posts

I am busy building a small theme options page for one of clients and need some help with an issue.

currently i have the option to manually put in IDS of wordpress pages to extract the data with query_posts

based on the theme开发者_如何学运维 options is creates a variable called $euro_box_1_vehicles;

my options are filled in as 32,39,43,54 in the input, and when I print this statement with echo, I get the same result.

When I just replace array(32,39,43,45) with array($euro_box_1_vehicles) it only returns one result.

<?php
    $vehicle1 = array(
        'post__in' => array(32,39,43,45),
        'post_type' => 'page',
    );

    query_posts( $vehicle1 ); 
    while (have_posts()) : the_post(); 
?>

When I echo var_dump = string(11) "32,39,43,45"

In which case, you need to explode $vehicle1, since post__in expects an array;

query_posts(array(
    'post_type' => 'page',
    'post__in' => @explode(',', $vehicle1)
));

Update

When I just replace array(32,39,43,45) with array($euro_box_1_vehicles) it only returns one result.

Shouldn't you replace array(32,39,43,45) with $euro_box_1_vehicles not array($euro_box_1_vehicles)? The latter seems it would make a nested array with one argument, i.e. array(array(32,39,43,45)). Which is not what you want.

Old Answer....

If I read you right then query_posts() expects a list of IDs? (32,39,43,45)

But when you pass it $vehicle1 you are not giving it a list of IDs, but a 2-dimensional array.

<?php
    $vehicle1 = array(
        'post__in' => array(32,39,43,45),
        'post_type' => 'page',
    );

    query_posts( $vehicle1['post_in'] ); //use sub-array that contains list
    while (have_posts()) : the_post(); 
?>
