从Wordpress中的图库图像中删除宽度和高度


Remove width and height from gallery images in Wordpress

我正在修改WP安装。

我正在使用修改后的图库短代码来显示图库,并使用过滤器来删除保持页面响应所需的宽度和高度参数。

我的问题是当我链接到附件页面(默认)时,画廊显示正确。但是,当我将缩略图链接到文件时,过滤器不会删除宽度和高度参数。

这是过滤器:

/** remove gallery height and width*/
add_image_size( 'my_gallery_shortcode', 200, 120, true );
add_filter('wp_get_attachment_link', 'remove_img_width_height', 10, 4);
function remove_img_width_height( $html, $post_id, $post_image_id, $post_thumbnail) {
if ($post_thumbnail=='my_gallery_shortcode'){
$html = preg_replace( '/(width|height)='"'d*'"'s/', "", $html );
}
return $html;
}
/** END remove gallery height and width*/

这是自定义库代码:

/** custom gallery code */
add_shortcode('gallery', 'my_gallery_shortcode');    
function my_gallery_shortcode($attr) {
    $post = get_post();
static $instance = 0;
$instance++;
if ( ! empty( $attr['ids'] ) ) {
    // 'ids' is explicitly ordered, unless you specify otherwise.
    if ( empty( $attr['orderby'] ) )
        $attr['orderby'] = 'post__in';
    $attr['include'] = $attr['ids'];
}
// Allow plugins/themes to override the default gallery template.
$output = apply_filters('post_gallery', '', $attr);
if ( $output != '' )
    return $output;
// We're trusting author input, so let's at least make sure it looks like a valid orderby statement
if ( isset( $attr['orderby'] ) ) {
    $attr['orderby'] = sanitize_sql_orderby( $attr['orderby'] );
    if ( !$attr['orderby'] )
        unset( $attr['orderby'] );
}
extract(shortcode_atts(array(
    'order'      => 'ASC',
    'orderby'    => 'menu_order ID',
    'id'         => $post->ID,

    'include'    => '',
    'exclude'    => ''
), $attr));
$id = intval($id);
if ( 'RAND' == $order )
    $orderby = 'none';
if ( !empty($include) ) {
    $_attachments = get_posts( array('include' => $include, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $order, 'orderby' => $orderby) );
    $attachments = array();
    foreach ( $_attachments as $key => $val ) {
        $attachments[$val->ID] = $_attachments[$key];
    }
} elseif ( !empty($exclude) ) {
    $attachments = get_children( array('post_parent' => $id, 'exclude' => $exclude, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $order, 'orderby' => $orderby) );
} else {

}
if ( empty($attachments) )
    return '';
if ( is_feed() ) {
    $output = "'n";
    foreach ( $attachments as $att_id => $attachment )
        $output .= wp_get_attachment_link($att_id, $size, true) . "'n";
    return $output;

$output = apply_filters( 'gallery_style', $gallery_style . "'n't't" . $gallery_div );
$i = 0;
foreach ( $attachments as $id => $attachment ) {
    $link = isset($attr['link']) && 'file' == $attr['link'] ? wp_get_attachment_link($id, $size, false, false) : wp_get_attachment_link($id, $size, true, false);
    $output .= "<{$itemtag} class='gallery-item'>";
    $output .= "

            $link
        </{$icontag}>";
    if ( $captiontag && trim($attachment->post_excerpt) ) {
        $output .= "
            <{$captiontag} class='wp-caption-text gallery-caption'>
            " . wptexturize($attachment->post_excerpt) . "
            </{$captiontag}>";
    }

$output .= "
    </div>'n";
return $output;
}

任何人都可以帮助确保所有大小的库缩略图图像在没有尺寸的情况下显示,无论它们链接到什么?

要制作响应式画廊,您真的不需要从 IMG 中删除所有高度和体重标签。您需要做的就是在图像标签中添加一些css。

例如:

<div class="facebook">
  <img src="http:///" height="100" width="100" >

要使此图像响应,请添加此 css

  div.facebook img
   { 
    width: 100%;
   }

如果您在使用古腾堡博客编辑器添加图像时遇到问题,请在 css 文件中使用此 css 来设置自动宽度和高度,这样就没有问题了:

figure > img {
width: auto;
height: auto;}
