如何测试帖子是否为自定义帖子类型？

您在这里: get_post_type() ,然后是if ( 'book' == get_post_type() ) ...根据Codex中的条件标签>帖子类型./p>

Here you are: get_post_type() and then if ( 'book' == get_post_type() ) ... as per Conditional Tags > A Post Type in Codex.

 if ( is_singular( 'book' ) ) {
    // conditional content/code
}
 

当查看自定义帖子类型的帖子:true时,以上为book.

 if ( is_singular( array( 'newspaper', 'book' ) ) ) {
    //  conditional content/code
}
 

当查看以下自定义帖子类型的帖子时,以上为book:newspaper或true.

这些和更多条件标签可以在此处查看.

if ( is_singular( 'book' ) ) {
    // conditional content/code
}

The above is true when viewing a post of the custom post type: book.

if ( is_singular( array( 'newspaper', 'book' ) ) ) {
    //  conditional content/code
}

The above is true when viewing a post of the custom post types: newspaper or book.

These and more conditional tags can be viewed here.

将其添加到您的functions.php中,就可以在循环内或循环外使用该功能:

 function is_post_type($type){
    global $wp_query;
    if($type == get_post_type($wp_query->post->ID)) 
        return true;
    return false;
}
 

因此您现在可以使用以下内容:

 if (is_single() && is_post_type('post_type')){
    // Work magic
}
 

Add this to your functions.php, and you can have the functionality, inside or outside of the loop:

function is_post_type($type){
    global $wp_query;
    if($type == get_post_type($wp_query->post->ID)) 
        return true;
    return false;
}

So you can now use the following:

if (is_single() && is_post_type('post_type')){
    // Work magic
}

要测试帖子是否为任何个自定义帖子类型,请获取所有非内置帖子类型的列表,并测试该帖子的类型是否在该列表中.

功能:

 /**
 * Check if a post is a custom post type.
 * @param  mixed $post Post object or ID
 * @return boolean
 */
function is_custom_post_type( $post = NULL )
{
    $all_custom_post_types = get_post_types( array ( '_builtin' => FALSE ) );

    // there are no custom post types
    if ( empty ( $all_custom_post_types ) )
        return FALSE;

    $custom_types      = array_keys( $all_custom_post_types );
    $current_post_type = get_post_type( $post );

    // could not detect current type
    if ( ! $current_post_type )
        return FALSE;

    return in_array( $current_post_type, $custom_types );
}
 

用法:

 if ( is_custom_post_type() )
    print 'This is a custom post type!';
 

To test if a post is any custom post type, fetch the list of all not built-in post types and test if the post’s type is in that list.

As a function:

/**
 * Check if a post is a custom post type.
 * @param  mixed $post Post object or ID
 * @return boolean
 */
function is_custom_post_type( $post = NULL )
{
    $all_custom_post_types = get_post_types( array ( '_builtin' => FALSE ) );

    // there are no custom post types
    if ( empty ( $all_custom_post_types ) )
        return FALSE;

    $custom_types      = array_keys( $all_custom_post_types );
    $current_post_type = get_post_type( $post );

    // could not detect current type
    if ( ! $current_post_type )
        return FALSE;

    return in_array( $current_post_type, $custom_types );
}

Usage:

if ( is_custom_post_type() )
    print 'This is a custom post type!';

如果由于某种原因您已经可以访问全局变量$post,则可以简单地使用

 if ($post->post_type == "your desired post type") {
}
 

If for any reason you already have access to the global variable $post, you can simply use

if ($post->post_type == "your desired post type") {
}

如果您想要通配符检查所有自定义帖子类型:

 if( ! is_singular( array('page', 'attachment', 'post') ) ){
    // echo 'Imma custom post type!';
}
 

这样,您无需知道自定义帖子的名称.即使以后更改自定义帖子的名称,该代码也仍然有效.

If you want a wild card check for all your custom post types:

if( ! is_singular( array('page', 'attachment', 'post') ) ){
    // echo 'Imma custom post type!';
}

This way you don't need to know the name of your custom post. Also the code still work even if you change the name of your custom post later.
