我使用下面的代码在“媒体库”列中显示alt标记，但我还使用额外的列/代码来显示图像尺寸。现在唯一的问题是，尺寸标注也显示在alt tag列中。将标注数据添加到alt文本的代码中是什么？
希望有人能帮我，谢谢！
function wpse_media_extra_column( $cols ) {
$cols["alt"] = "ALT";
return $cols;
}
function wpse_media_extra_column_value( $column_name, $id ) {
if( $column_name == \'alt\' )
echo get_post_meta( $id, \'_wp_attachment_image_alt\', true);
}
add_filter( \'manage_media_columns\', \'wpse_media_extra_column\' );
add_action( \'manage_media_custom_column\', \'wpse_media_extra_column_value\', 10, 2 );
function wh_column( $cols ) {
$cols["dimensions"] = "Dimensions (w, h)";
return $cols;
}
function wh_value( $column_name, $id ) {
$meta = wp_get_attachment_metadata($id);
if(isset($meta[\'width\']))
echo $meta[\'width\'].\' x \'.$meta[\'height\'];
}
add_filter( \'manage_media_columns\', \'wh_column\' );
add_action( \'manage_media_custom_column\', \'wh_value\', 10, 2 );

无需每次添加新的管理列时都创建新函数。您可以使用以下功能在单独的管理列中显示两个媒体数据。
function column_id($columns) {
$columns[\'media_alt\'] = __(\'Alt\');
$columns[\'media_dimensions\'] = __(\'Dimensions\');
return $columns;
}
add_filter( \'manage_media_columns\', \'column_id\' );
function column_id_row($columnName, $columnID){
if ( $columnName == \'media_alt\') {
$image_alt = get_post_meta($columnID, \'_wp_attachment_image_alt\', true);
echo $image_alt;
}
if ( $columnName == \'media_dimensions\') {
$image_size = wp_get_attachment_image_src($columnID, \'full\');
if ( $image_size ) {
echo $image_size[1] . \' x \' . $image_size[2];
}
}
}
add_filter( \'manage_media_custom_column\', \'column_id_row\', 10, 2 );
