PHP loop that selects posts with a particular in-post option

Question

All you need is a simple query and to iterate over that query a couple of times so you can build the two required lists. WP_Query has a convenient method for resetting the pointer in the posts array, so you can loop over it again, called rewind_posts though i believe inside custom loops you have to reference the method directly..

Anyway, here’s the kind of thing you’re looking for, simply make adjustments as necessary..

<?php   
    $featured = new WP_Query;
    $featured->query( array( 
        'meta_query'  => array( 
            array(
                'key'     => 'myslider_show_post_slider',
                'value'   => array('on','1'),
                'compare' => 'IN',
                'type'    => 'CHAR',
            )
        ),
        'post_type'       => 'post',
        'post_status'     => 'publish',
        'ignore_sticky_posts' => '1',
        'posts_per_page' => '7' //The number of post in the slider.
    ) );
    if( $featured->have_posts() ) :
    ?>

    <div class="slider">
        <ul class="main-wapper">

        <?php
        while( $featured->have_posts() ) : $featured->the_post();
        ?>

        <li>
            <?php the_post_thumbnail(); ?>
            <div class="main-item-desc">
                <h2><a title="<?php the_title_attribute(); ?>" href="https://wordpress.stackexchange.com/questions/14396/<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
                <p>Where's this description suppose to be coming from?</p>
            </div>
      </li>

        <?php
        endwhile;
        $featured->rewind_posts();
        ?>

        </ul>
    </div>
    <div class="navigator-outer">
        <ul class="navigator">

        <?php
        while( $featured->have_posts() ) : $featured->the_post();
        ?>

        <li>
            <div>
                 <?php the_post_thumbnail('Slider'); ?>
                <h3><?php the_title(); ?></h3>
                <p><span class="date"><?php the_time( 'd.m.Y' ); ?></span> | <span class="category"><?php the_category(','); ?></span></p>
            </div>
        </li>

        <?php
        endwhile;
        ?>

        </ul>
    </div>

    <?php
    endif; 
    ?>

Firstly, there was a stray closing DIV in the HTML you posted, so i simply removed that from the code above.

Secondly, the checkbox does not have a value specified, in such cases a checkbox isn’t given a specific value, the browser assigns the checkbox one, i’m not sure whether there’s a common value that all browsers will use, but Firefox produces the value on, but i accounted for the possibility that the browser may assign a value of 1, ideally the checkbox should be given a implicit value to ensure consistent behaviour, eg..

echo '<input type="checkbox" value="1" name="', $field['id'], '" id="', $field['id'], '"', $meta ? ' checked="checked"' : '', ' />';

Any questions, lemme know..
