WordPress如何判断当前文章是否是密码保护文章

WordPress如何判断当前文章是否是密码保护文章，下面web建站小编给大家简单介绍一下具体运用方法！

函数源码：

function post_password_required( $post = null ) {
  $post = get_post( $post );

  if ( empty( $post->post_password ) ) {
    return apply_filters( 'post_password_required', false, $post );
  }

  if ( ! isset( $_COOKIE[ 'wp-postpass_' . COOKIEHASH ] ) ) {
    return apply_filters( 'post_password_required', true, $post );
  }

  require_once ABSPATH . WPINC . '/class-phpass.php';
  $hasher = new PasswordHash( 8, true );

  $hash = wp_unslash( $_COOKIE[ 'wp-postpass_' . COOKIEHASH ] );
  if ( 0 !== strpos( $hash, '$P$B' ) ) {
    $required = true;
  } else {
    $required = ! $hasher->CheckPassword( $post->post_password, $hash );
  }

  return apply_filters( 'post_password_required', $required, $post );
}

apply_filters( 'post_password_required', bool $required, WP_Post $post )

使用示例：

$pass_masterPost = get_post();
if ( post_password_required(  $pass_masterPost->ID ) )
{
  echo get_the_password_form();
  echo '<p>THIS POST IS PASSWORD PROTECTED: PLEASE ENTER IT!</p>';
}
else
{
  if ( have_posts() )
  { 
    while ( have_posts() ) 
    {    
      the_post();
      the_content();
	  echo '<hr>';
     }  
  }
  else
  {
    echo '<p>Nothing Found!</p>';
  }
}
