从 Wordpress 中的图库图像中删除宽度和高度

Question

我正在修改 WP 安装。

我正在使用修改后的图库简码来显示图库，并使用过滤器删除宽度和高度参数，这是保持页面响应所必需的。

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*/

这是自定义画廊代码：

/** 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',
    'icontag'    => 'dt',
    'captiontag' => 'dd',
    '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 {
    $attachments = get_children( array('post_parent' => $id, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $order, 'orderby' => $orderby) );
}

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 );

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

}

$output .= "
    </div>\n";

return $output;
}

任何人都可以帮助确保所有尺寸的画廊缩略图都无尺寸显示，而不管它们链接到什么？

Answer 1

要制作响应式图库，您确实不需要从 IMG 中删除所有高度和体重标签。 您需要做的就是向您的图像标签添加一些 css。

例如：

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

要使此图像响应添加此 css

  div.facebook img
   { 
    width: 100%;
   }

Answer 2

如果在使用Gutenberg 博客编辑器添加图像时遇到问题，请在 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;}
