Question

我正在修改WP安装。

我使用修改过的Gallery短代码来显示图库，并使用过滤器来删除宽度和高度参数，以保持页面响应。

我的问题是当我链接到附件页面时（默认情况下）画廊显示正常。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*/

这是自定义图库代码：

/** 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,
    'itemtag'    => 'dl',

    'columns'    => 3,
    'size'       => 'medium',
    '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;
}

$itemtag = tag_escape($itemtag);
$captiontag = tag_escape($captiontag);
$icontag = tag_escape($icontag);
$valid_tags = wp_kses_allowed_html( 'post' );
if ( ! isset( $valid_tags[ $itemtag ] ) )
    $itemtag = 'dl';
if ( ! isset( $valid_tags[ $captiontag ] ) )
    $captiontag = 'dd';
if ( ! isset( $valid_tags[ $icontag ] ) )
    $icontag = 'dt';

$columns = intval($columns);
$itemwidth = $columns > 0 ? floor(100/$columns) : 100;
$float = is_rtl() ? 'right' : 'left';

$selector = "gallery-{$instance}";

$gallery_style = $gallery_div = '';

$size_class = sanitize_html_class( $size );
$gallery_div = "<div id='$selector' class='gallery galleryid-{$id} gallery-columns-{$columns} gallery-size-{$size_class}'>";
$output = apply_filters( 'gallery_style', $gallery_style . "\n\t\t" . $gallery_div );

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

    </div>\n";

return $output;
}

任何人都可以帮助确保所有尺寸的图库缩略图图像都显示为没有尺寸，无论它们链接到什么？

Answer 1

要制作响应式图库，您真的不需要从IMG中删除所有身高和体重标签。您需要做的就是为图像标记添加一些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%;
   }

Answer 2

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

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