I am getting “ERR_CONNECTION_RESET” messages when I do try to access edit.php, theme.php on all of my child themes…

So with some research, seeing that there is no way to really restrict the options within the Page Attributes meta box, I had to remove the Page Attributes meta box and then add it back in for the “Page” post type. From there I was able to wrap the “Template” and “Order” fields within DIVs with IDs so I could isolate them out.

My solution was modified on this page [http://wordpress.stackexchange.com/questions/90903/how-to-remove-the-template-drop-down-but-keep-parent-and-order] and also utilizing Adminimize [http://wordpress.org/plugins/adminimize/] to hide items by role and specific ID for post type.

<?php
/************* CUSTOMIZE Page Attributes *******************/
function remove_post_custom_fields() {
	remove_meta_box( 'pageparentdiv' , 'page' , 'side' );
    }
    add_action( 'admin_menu' , 'remove_post_custom_fields' );

    function add_post_custom_fields() {
        add_meta_box('pageparentdiv', 'Page Attributes', 'my_page_attributes_meta_box', 'page', 'side');
    }
    add_action( 'admin_menu' , 'add_post_custom_fields' );
    function my_page_attributes_meta_box($post) {
    $post_type_object = get_post_type_object($post->post_type);
    if ( $post_type_object->hierarchical ) {
        $dropdown_args = array(
            'post_type'        => $post->post_type,
            'exclude_tree'     => $post->ID,
            'selected'         => $post->post_parent,
            'name'             => 'parent_id',
            'show_option_none' => __('(no parent)'),
            'sort_column'      => 'menu_order, post_title',
            'echo'             => 0,
        );
        $dropdown_args = apply_filters( 'page_attributes_dropdown_pages_args',   $dropdown_args, $post );
        $pages = wp_dropdown_pages( $dropdown_args );
        if ( ! empty($pages) ) {
    ?>
    <p><strong><?php _e('Parent') ?></strong></p>
    <label class="screen-reader-text" for="parent_id"><?php _e('Parent') ?></label>
    <?php echo $pages; ?>
    <?php
        } // end empty pages check
    } // end hierarchical check.
    if ( 'page' == $post->post_type && 0 != count( get_page_templates() ) ) {
        $template = !empty($post->page_template) ? $post->page_template : false;
        ?>
    <div id="pagetemplatediv">
        <p><strong><?php _e('Template') ?></strong></p>
        <label class="screen-reader-text" for="page_template"><?php _e('Page Template') ?></label>
        <select name="page_template" id="page_template">
            <option value='default'><?php _e('Default Template'); ?></option>
            <?php page_template_dropdown($template); ?>
        </select>
     <?php } ?>
    </div>
    <div id="pageorderdiv">
        <p><strong><?php _e('Order') ?></strong></p>
        <p><label class="screen-reader-text" for="menu_order"><?php _e('Order') ?></label>
        <input name="menu_order" type="text" size="4" id="menu_order" value="<?php echo esc_attr($post->menu_order) ?>" /></p>
    </div>
    <p><?php if ( 'page' == $post->post_type ) _e( 'Need Help? Use the Help tab in the upper right of your screen.' ); ?></p>
    <?php } ?>

Of course, if there is a better way to be able to remove the Template and Order fields based on user roles without having to remove the meta box from the core functionality, I am open to better suggestions!

The problem would be that it’s a slideshow of images being pulled from a custom post type called “slides”. I want to loop through each custom post type and extract the “post thumbnail” and cycle through the different images on my page. If it was a static image, I could serve the image up with different stylesheets/media queries.

How would I go about having JavaScript/jQuery tell PHP to load a different image size based on the screen width?
