如果没有附件，如何隐藏img标签？

（函数来自本教程：http://wp.tutsplus.com/tutorials/automagic-post-thumbnails-image-management/)

<img src="<?php get_attachment_picture();?>" />

我需要这样的东西：

<?php if ( get_attachment_picture()) { ?>
<img src="<?php get_attachment_picture();?>">
<?php } else { ?>
show nothing, not even av default image
<?php } ?>

以下是我使用的函数：

<!?php 

/* Function to process your thumbnail & image
   Copy and paste the code below to your functions.php */

function get_attachment_picture(){
    global $post, $posts;
    $related_thumbnail =  get_post_meta($post->ID, \'image\', $single = true);                            //read post meta for image url

    if($related_thumbnail == ""):
        $attachments = get_children( array(
                                    \'post_parent\'    => get_the_ID(),
                                    \'post_type\'      => \'attachment\',
                                    \'numberposts\'    => 1,
                                    \'post_status\'    => \'inherit\',
                                    \'post_mime_type\' => \'image\',
                                    \'order\'          => \'ASC\',
                                    \'orderby\'        => \'menu_order ASC\'
                                    ) );
        if(!empty($attachments)):                                               //check if there an attachment or not
            foreach ( $attachments as $attachment_id => $attachment ) {
              if(wp_get_attachment_image($attachment_id) != ""):
                  $related_thumbnail = wp_get_attachment_url( $attachment_id );
              endif;
            }
        else:                                                           // if no attachment
            $first_img = \'\';
            ob_start();
            ob_end_clean();
            $output = preg_match_all(\'/<img.+src=[\\\'"]([^\\\'"]+)[\\\'"].*>/i\', $post->post_content, $matches);
            $first_img = $matches [1] [0];

            if(!empty($first_img)):
                $related_thumbnail = $first_img;
            else:
                $related_thumbnail = "images/default_thumbnail.jpg";                            //define default thumbnail, you can use full url here.
            endif;
        endif;
    endif;  

    echo $related_thumbnail;
} ?>

// get the URL of the image $src = get_attachment_picture(); // if the url is not empty, display the image if(!empty($src)){ ?> <img src="<?php echo $src; ?>" /> <?php } else { // the url was empty, do not display the image }

function get_attachment_picture(){ global $post, $posts; $related_thumbnail = get_post_meta($post->ID, \'image\', true); //read post meta for image url if($related_thumbnail == ""): $attachments = get_children( array( \'post_parent\' => get_the_ID(), \'post_type\' => \'attachment\', \'numberposts\' => 1, \'post_status\' => \'inherit\', \'post_mime_type\' => \'image\', \'order\' => \'ASC\', \'orderby\' => \'menu_order ASC\' ) ); if(!empty($attachments)): //check if there an attachment or not foreach ( $attachments as $attachment_id => $attachment ) { if(wp_get_attachment_image($attachment_id) != ""): $related_thumbnail = wp_get_attachment_url( $attachment_id ); endif; } else: // if no attachment $first_img = \'\'; $output = preg_match_all(\'/<img.+src=[\\\'"]([^\\\'"]+)[\\\'"].*>/i\', $post->post_content, $matches); $first_img = $matches [1] [0]; if(!empty($first_img)): $related_thumbnail = $first_img; else: $related_thumbnail = ""; endif; endif; endif; return $related_thumbnail; }

使用htaccess将wp-Content/Themes/Name/Images掩蔽为仅图像目录

我正在尝试一些我认为非常简单的方法来屏蔽我的url，但似乎无法使其正常工作。我希望能够链接到我的img标签中的图像，而不必键入完整的url。i、 e。Current url: http://server.com/wp-content/themes/standard/images/img.jpg or <img src = \"http://server.com/wp-content/themes/standard/images/img.jpg\" /> 然而，在我的
