我没有使用PHP的经验。我使用ACF选择字段，让客户可以在单个页面、帖子和存档级别选择样式表。仅供参考，根据内容类型，字段为singular_css, portfolio_css和careers_css，并共享这些下拉值:
/wp-content/themes/hello-theme-child-master/custom-css/white.css : White
/wp-content/themes/hello-theme-child-master/custom-css/black.css : Black
/wp-content/themes/hello-theme-child-master/custom-css/blue.css : Blue
/wp-content/themes/hello-theme-child-master/custom-css/tan.css : Tan
/wp-content/themes/hello-theme-child-master/custom-css/gray.css : Gray
functions.php中的这个脚本似乎可以像预期的那样控制在单个post/page上加载的样式表，但不允许它们为自定义post类型存档选择样式表:
/** Insert Dynamic Stylesheet Into <Head> using ACF Field **/
add_action( 'wp_head', 'add_head_script' );
function add_head_script() { ?>
<?php
$singular_css = get_field('singular_css');
if( $singular_css ): ?>
<link rel="stylesheet" href="<?php echo esc_url( $singular_css ); ?>">
<?php endif; ?>
<?php }
由于我无法以同样的方式控制自定义邮件存档的样式表，因此我为它们创建了选项页面:
/** Creates ACF Options Pages **/
if( function_exists('acf_add_options_page') ) {
acf_add_options_sub_page(array(
'page_title' => 'Portfolio Style',
'menu_title' => 'Portfolio Style',
'parent_slug' => 'edit.php?post_type=portfolio',
'capability' => 'manage_options'
));
acf_add_options_sub_page(array(
'page_title' => 'Careers Style',
'menu_title' => 'Careers Style',
'parent_slug' => 'edit.php?post_type=careers',
'capability' => 'manage_options'
));
}
并尝试将样式表排队，但有些东西不起作用:
/** Enqueue Dynamic Stylesheet using ACF Field **/
function dynamic_style() {
$singular_css = get_field('singular_css');
$portfolio_css = get_field('portfolio_css', 'option');
$careers_css = get_field('careers_css', 'option');
if (is_singular()) {
wp_enqueue_style( 'singular_css', get_stylesheet_directory_uri(). $singular_css );
}
elseif (is_post_type_archive('portfolio')) {
wp_enqueue_style( 'portfolio_css', get_stylesheet_directory_uri(). $portfolio_css );
}
elseif (is_post_type_archive('careers')) {
wp_enqueue_style( 'careers_css', get_stylesheet_directory_uri(). $careers_css );
}
}
add_action( 'wp_enqueue_scripts', 'dynamic_style' );
我也试着这样写，但它仍然不工作:
/** Enqueue Dynamic Stylesheet using ACF Field **/
function singular_style() {
$singular_css = get_field('singular_css');
if (is_singular()) {
wp_enqueue_style( 'singular_css', get_stylesheet_directory_uri(). $singular_css );
}
}
add_action( 'wp_enqueue_scripts', 'singular_style' );
function portfolio_style() {
$portfolio_css = get_field('portfolio_css', 'option');
if (is_post_type_archive('portfolio')) {
wp_enqueue_style( 'portfolio_css', get_stylesheet_directory_uri(). $portfolio_css );
}
}
add_action( 'wp_enqueue_scripts', 'portfolio_style' );
function careers_style() {
$careers_css = get_field('careers_css', 'option');
if (is_post_type_archive('careers')) {
wp_enqueue_style( 'careers_css', get_stylesheet_directory_uri(). $careers_css );
}
}
add_action( 'wp_enqueue_scripts', 'careers_style' );
我建议你将下拉列表的值改为
/custom-css/white.css : White
/custom-css/black.css : Black
/custom-css/blue.css : Blue
/custom-css/tan.css : Tan
/custom-css/gray.css : Gray
然后在functions.php文件
中添加以下代码function dynamic_style()
{
if (is_singular()) {
global $post;
$cog_stylesheet = get_field('cog_background_color', $post->ID);
wp_enqueue_style('singular_css', get_stylesheet_directory_uri() . $cog_stylesheet);
}else {
global $post;
$post_type = get_current_post_types($post);
if ($post_type == 'portfolio') {
$portfolio_css = get_field('portfolio_css', 'option');
wp_enqueue_style('portfolio_css', get_stylesheet_directory_uri() . $portfolio_css);
} elseif ($post_type == 'careers') {
$careers_css = get_field('careers_css', 'option');
wp_enqueue_style('careers_css', get_stylesheet_directory_uri() . $careers_css);
}
}
}
add_action('wp_enqueue_scripts', 'dynamic_style');
但是，如果您仍然希望使用当前的下拉值，请将functions.php文件中的以下代码添加到
function dynamic_style()
{
if (is_singular()) {
global $post;
$cog_stylesheet = get_field('cog_background_color', $post->ID);
wp_enqueue_style('singular_css', home_url() . $cog_stylesheet);
} else {
global $post;
$post_type = get_current_post_types($post);
if ($post_type == 'portfolio') {
$portfolio_css = get_field('portfolio_css', 'option');
wp_enqueue_style('portfolio_css', home_url() . $portfolio_css);
} elseif ($post_type == 'careers') {
$careers_css = get_field('careers_css', 'option');
wp_enqueue_style('careers_css', home_url() . $careers_css);
}
}
}
add_action('wp_enqueue_scripts', 'dynamic_style');
并在functions.php中添加以下代码，以便我们可以在存档页
上获取post_typefunction get_current_post_types($object = null)
{
// if a numeric value passed, assume it is a post ID
if (($object) && (is_numeric($object))) {
$object = get_post($object);
}
// if an object is passed, assume to be a post object
if (($object) && (is_object($object))) {
return get_post_type($object);
}
// standard single post type checks
if (is_404()) {
return '';
}
// update: removed this check, handled by is_singular
// if (is_single()) {return 'post';}
if (is_page()) {
return 'page';
}
if (is_attachment()) {
return 'attachment';
}
if (is_singular()) {
return get_post_type();
}
// if a custom query object was not passed, use $wp_query global
if ((!$object) || (!is_object($object))) {
global $wp_query;
$object = $wp_query;
}
if (!is_object($object)) {
return '';
} // should not fail
// if the post_type query var has been explicitly set
// (or implicitly set on the cpt via a has_archive redirect)
// ie. this is true for is_post_type_archive at least
// $vqueriedposttype = get_query_var('post_type'); // $wp_query only
if (property_exists($object, 'query_vars')) {
$posttype = $object->query_vars['post_type'];
if ($posttype) {
return $posttype;
}
}
谢谢Bijay!你帮了大忙了。下面是我所采取的步骤:
我注册了这些选项页:
/** Creates ACF Options Pages **/
if( function_exists('acf_add_options_page') ) {
acf_add_options_sub_page(array(
'page_title' => 'Posts Style',
'menu_title' => 'Posts Stylesheet',
'parent_slug' => 'edit.php',
'capability' => 'manage_options'
));
acf_add_options_sub_page(array(
'page_title' => 'Portfolio Style',
'menu_title' => 'Portfolio Stylesheet',
'parent_slug' => 'edit.php?post_type=portfolio',
'capability' => 'manage_options'
));
acf_add_options_sub_page(array(
'page_title' => 'Careers Style',
'menu_title' => 'Careers Stylesheet',
'parent_slug' => 'edit.php?post_type=careers',
'capability' => 'manage_options'
));
}
我创建了ACF选择字段:
- singular_css
- articles_css
- portfolio_css
- careers_css
它们都有这些下拉值
- /custom-css/White .css: White
- /custom-css/Black .css: Black
- /custom-css/Blue .css: Blue
- /custom-css/Tan .css: Tan
- /custom-css/Gray .css: Gray
functions.php文件中的代码:
/** Enqueue Dynamic Stylesheet using ACF Field **/
function dynamic_style()
{
if (is_singular()) {
global $post;
$singular_css = get_field('singular_css', $post->ID);
wp_enqueue_style('singular_css', get_stylesheet_directory_uri(). $singular_css);
} elseif (is_home()) {
$articles_css = get_field('articles_css', 'option');
wp_enqueue_style('articles_css', get_stylesheet_directory_uri(). $articles_css);
} elseif (is_post_type_archive('portfolio')) {
$portfolio_css = get_field('portfolio_css', 'option');
wp_enqueue_style('portfolio_css', get_stylesheet_directory_uri(). $portfolio_css);
} elseif (is_post_type_archive('careers')) {
$careers_css = get_field('careers_css', 'option');
wp_enqueue_style('careers_css', get_stylesheet_directory_uri(). $careers_css);
} elseif (is_404()) {
wp_enqueue_style('white_css', get_stylesheet_directory_uri(). '/custom-css/white.css');
}
}
add_action('wp_enqueue_scripts', 'dynamic_style', 99);
