获取图像描述


10

我正在尝试将帖子分为2列。第一个和左边的将是帖子内的任何图像,第二个和右边的将是the_content()(不包括图像)。

因此,到目前为止,我可以轻松提取所有图像。但是-我似乎无法获得图像标题,标题或描述。

这是我的代码:

<?php if ( $images = get_posts(array(
        'post_parent' => $post->ID,
        'post_type' => 'attachment',
        'numberposts' => -1,
        'orderby'        => 'title',
        'order'           => 'ASC',
        'post_mime_type' => 'image',
    )))
    {
        foreach( $images as $image ) {
            $attachmenturl = wp_get_attachment_url($image->ID);
            $attachmentimage = wp_get_attachment_image_src( $image->ID, full );
            $imageDescription = apply_filters( 'the_description' , $image->post_content );
            $imageTitle = apply_filters( 'the_title' , $image->post_title );
            $i++;
            if (!empty($imageTitle)) {
                echo '<div class="client-img-item ci-'.$count++.'"><img src="' . $attachmentimage[0] . '" alt="'.$imageTitle.'"  /> <div class="CAPS client-img-caption"><span class="red arrow-lrg">»</span> '.$imageDescription.'</div></div><div class="sml-dots"></div>';
} else { echo '<img src="' . $attachmentimage[0] . '" alt="" />' ; }
        }
    } else {
        echo 'No Image Found';
    }?>

从WordPress 3.5.0开始,wp_prepare_attachment_for_js( $attachment ) 将达到目的:)

function wp_get_attachment( $attachment_id ) {

$attachment = get_post( $attachment_id );
return array(
    'alt' => get_post_meta( $attachment->ID, '_wp_attachment_image_alt', true ),
    'caption' => $attachment->post_excerpt,
    'description' => $attachment->post_content,
    'href' => get_permalink( $attachment->ID ),
    'src' => $attachment->guid,
    'title' => $attachment->post_title
);
}

正如sporkme稍后在线程中解释的那样,该变量被转储到您的functions.php中,然后可以使用进行调用$attachment_meta = wp_get_attachment(your_attachment_id);
