大家好，我最近在Wordpress主题上为flexslider创建了一个自定义帖子类型。然而，在测试时，它遇到了一些问题。滑块正在显示，但图像不会显示在其上。
我在这里创建了两个文件。滑块。php和slider\\u post\\u类型。php。
这是我在滑块上的代码。php：
<?php
// Enqueue Flexslider Files
function wptuts_slider_scripts() {
wp_enqueue_script( \'jquery\' );
wp_enqueue_style( \'flex-style\', get_template_directory_uri() . \'/inc/slider/css/flexslider.css\' );
wp_enqueue_script( \'flex-script\', get_template_directory_uri() . \'/inc/slider/js/jquery.flexslider-min.js\', array( \'jquery\' ), false, true );
}
add_action( \'wp_enqueue_scripts\', \'wptuts_slider_scripts\' );
// Initialize Slider
function wptuts_slider_initialize() { ?>
<script type="text/javascript" charset="utf-8">
jQuery(window).load(function() {
jQuery(\'.flexslider\').flexslider({
animation: "fade",
direction: "horizontal",
slideshowSpeed: 7000,
animationSpeed: 600
});
});
</script>
<?php }
add_action( \'wp_head\', \'wptuts_slider_initialize\' );
// Create Slider
function wptuts_slider_template() {
// Query Arguments
$args = array(
\'post_type\' => \'slides\',
\'posts_per_page\' => 5
);
// The Query
$the_query = new WP_Query( $args );
// Check if the Query returns any posts
if ( $the_query->have_posts() ) {
// Start the Slider ?>
<div class="flexslider">
<ul class="slides">
<?php
// The Loop
while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<li>
<?php // Check if there\'s a Slide URL given and if so let\'s a link to it
if ( get_post_meta( get_the_id(), \'wptuts_slideurl\', true) != \'\' ) { ?>
<a href="<?php echo esc_url( get_post_meta( get_the_id(), \'wptuts_slideurl\', true ) ); ?>">
<?php }
// The Slide\'s Image
echo the_post_thumbnail();
// Close off the Slide\'s Link if there is one
if ( get_post_meta( get_the_id(), \'wptuts_slideurl\', true) != \'\' ) { ?>
</a>
<?php } ?>
</li>
<?php endwhile; ?>
</ul><!-- .slides -->
</div><!-- .flexslider -->
<?php }
// Reset Post Data
wp_reset_postdata();
}
这是slider\\u post\\u类型上的代码。php：
<?php
// Create Custom Post Type
function register_slides_posttype() {
$labels = array(
\'name\' => _x( \'Slides\', \'post type general name\' ),
\'singular_name\' => _x( \'Slide\', \'post type singular name\' ),
\'add_new\' => __( \'Add New Slide\' ),
\'add_new_item\' => __( \'Add New Slide\' ),
\'edit_item\' => __( \'Edit Slide\' ),
\'new_item\' => __( \'New Slide\' ),
\'view_item\' => __( \'View Slide\' ),
\'search_items\' => __( \'Search Slides\' ),
\'not_found\' => __( \'Slide\' ),
\'not_found_in_trash\'=> __( \'Slide\' ),
\'parent_item_colon\' => __( \'Slide\' ),
\'menu_name\' => __( \'Slides\' )
);
$taxonomies = array();
$supports = array(\'title\',\'thumbnail\');
$post_type_args = array(
\'labels\' => $labels,
\'singular_label\' => __(\'Slide\'),
\'public\' => true,
\'show_ui\' => true,
\'publicly_queryable\'=> true,
\'query_var\' => true,
\'capability_type\' => \'post\',
\'has_archive\' => false,
\'hierarchical\' => false,
\'rewrite\' => array(\'slug\' => \'slides\', \'with_front\' => false ),
\'supports\' => $supports,
\'menu_position\' => 27, // Where it is in the menu. Change to 6 and it\'s below posts. 11 and it\'s below media, etc.
\'menu_icon\' => get_template_directory_uri() . \'/inc/slider/images/icon.png\',
\'taxonomies\' => $taxonomies
);
register_post_type(\'slides\',$post_type_args);
}
add_action(\'init\', \'register_slides_posttype\');
// Meta Box for Slider URL
$slidelink_2_metabox = array(
\'id\' => \'slidelink\',
\'title\' => \'Slide Link\',
\'page\' => array(\'slides\'),
\'context\' => \'normal\',
\'priority\' => \'default\',
\'fields\' => array(
array(

\'desc\' => \'\',
\'id\' => \'wptuts_slideurl\',
\'class\' => \'wptuts_slideurl\',

),
)
);
add_action(\'admin_menu\', \'wptuts_add_slidelink_2_meta_box\');
function wptuts_add_slidelink_2_meta_box() {
global $slidelink_2_metabox;
foreach($slidelink_2_metabox[\'page\'] as $page) {

}
}
// function to show meta boxes
function wptuts_show_slidelink_2_box() {
global $post;
global $slidelink_2_metabox;
global $wptuts_prefix;
global $wp_version;
// Use nonce for verification

break;
}
echo \'<td>\',
\'</tr>\';
}
echo \'</table>\';
}
// Save data from meta box
add_action(\'save_post\', \'wptuts_slidelink_2_save\');
function wptuts_slidelink_2_save($post_id) {
global $post;
global $slidelink_2_metabox;
// verify nonce
if (!wp_verify_nonce($_POST[\'wptuts_slidelink_2_meta_box_nonce\'], basename(__FILE__))) {
return $post_id;
}
// check autosave
if (defined(\'DOING_AUTOSAVE\') && DOING_AUTOSAVE) {
return $post_id;
}
// check permissions
if (\'page\' == $_POST[\'post_type\']) {
if (!current_user_can(\'edit_page\', $post_id)) {
return $post_id;
}
} elseif (!current_user_can(\'edit_post\', $post_id)) {
return $post_id;
}
foreach ($slidelink_2_metabox[\'fields\'] as $field) {
$old = get_post_meta($post_id, $field[\'id\'], true);
$new = $_POST[$field[\'id\']];
if ($new && $new != $old) {
if($field[\'type\'] == \'date\') {
$new = wptuts_format_date($new);
update_post_meta($post_id, $field[\'id\'], $new);
} else {

$new = $new;
}
update_post_meta($post_id, $field[\'id\'], $new);
}
} elseif (\'\' == $new && $old) {
delete_post_meta($post_id, $field[\'id\'], $old);
}
}
}
我已经在我的函数中注册了这个。php文件：
// Create Slider Post Type
require( get_template_directory() . \'/inc/slider/slider_post_type.php\' );
// Create Slider
require( get_template_directory() . \'/inc/slider/slider.php\' );
以下是后端的外观：
现在，当我在索引上运行它时。下面是我的代码：
以下是我得到的输出：
你知道为什么这些图像不会出现吗？
