wordpress top主题v0.3版本，外链图片不显示缩略图

打开functions-theme.php找到如下代码：

function _get_post_thumbnail() {
    return ’<img src="’._the_theme_thumb().’" data-src="’. _get_post_thumbnail_url() .’" class="thumb">’;
}

function _get_post_thumbnail() {

return ’<img src="’._the_theme_thumb().’" data-src="’. _get_post_thumbnail_url() .’" class="thumb">’;

}

替换为如下代码：

function _get_post_thumbnail($size = ’thumbnail’, $class = ’thumb’) {
    global $post;
    $html = ’’;
    if (has_post_thumbnail()) {
 
        /*$domsxe = simplexml_load_string(get_the_post_thumbnail());
        $src = $domsxe->attributes()->src;
 
        $src_array = wp_get_attachment_image_src(_get_attachment_id_from_src($src), $size);
        $html = sprintf(’<img data-src="%s" class="%s"/>’, $src_array[0], $class);*/
 
        $domsxe = get_the_post_thumbnail();
        // print_r($domsxe);
        preg_match_all(’/<img.*?(?: |\t|\r|\n)?src=[’"]?(.+?)[’"]?(?:(?: |\t|\r|\n)+.*?)?>/sim’, $domsxe, $strResult, PREG_PATTERN_ORDER);
        $images = $strResult[1];
        foreach($images as $src){
            $html = sprintf(’<img data-src="%s" class="thumb">’, $src);
            break;
        }
 
    }else {
        $post_thumbnail_src = ’’;
        ob_start();
    ob_end_clean();
    $output = preg_match_all(’/<img.+src=[’"]([^’"]+)[’"].*>/i’, $post->post_content, $matches);
    $post_thumbnail_src = $matches [1] [0];   //获取该图片 src
    if(empty($post_thumbnail_src)){
        $random = mt_rand(1, 10);
        $post_thumbnail_src = get_bloginfo(’template_url’).’/img/pic/’.$random.’.jpg’;
        }
        $html = sprintf(’<img data-src="%s" class="thumb">’, $post_thumbnail_src);
    }
    return $html;
}

function _get_post_thumbnail($size = ’thumbnail’, $class = ’thumb’) {

global $post;

$html = ’’;

if (has_post_thumbnail()) {

/*$domsxe = simplexml_load_string(get_the_post_thumbnail());

$src = $domsxe->attributes()->src;

$src_array = wp_get_attachment_image_src(_get_attachment_id_from_src($src), $size);

$html = sprintf(’<img data-src="%s" class="%s"/>’, $src_array[0], $class);*/

$domsxe = get_the_post_thumbnail();

// print_r($domsxe);

preg_match_all(’/<img.*?(?: |\t|\r|\n)?src=[’"]?(.+?)[’"]?(?:(?: |\t|\r|\n)+.*?)?>/sim’, $domsxe, $strResult, PREG_PATTERN_ORDER);

$images = $strResult[1];

foreach($images as $src){

$html = sprintf(’<img data-src="%s" class="thumb">’, $src);

break;

}

}else {

$post_thumbnail_src = ’’;

ob_start();

ob_end_clean();

$output = preg_match_all(’/<img.+src=[’"]([^’"]+)[’"].*>/i’, $post->post_content, $matches);

$post_thumbnail_src = $matches [1] [0]; //获取该图片 src

if(empty($post_thumbnail_src)){

$random = mt_rand(1, 10);

$post_thumbnail_src = get_bloginfo(’template_url’).’/img/pic/’.$random.’.jpg’;

}

$html = sprintf(’<img data-src="%s" class="thumb">’, $post_thumbnail_src);

}

return $html;

}
