Wordpress comes with 7 primary template page types, which can be determined on this way

if ( is_main_query() ) {
    // Error
    if ( is_404() ) {
        ;
    }
    // Front page
    if ( is_front_page() ) {
        ;
    }
    // Archive
    if ( is_archive() ) {
        ;
    }
    // Comments popup
    if ( is_comments_popup() ) {
        ;
    }
    // Search
    if ( is_search() ) {
        ;
    }
    // Singular
    if ( is_singular() ) {
        ;
    }
    // Home - the blog page
    if ( is_home() ) {
        ;
    }
}

is_home tells to you, that you have the blog page.

"Posts Page" égeralmente um arquivo de:

• posts de uma categoria
• posts de umatag
• posts de uma data (ano,mês ...)
• posts do Arquivo Principal

Cada um delespode ser verificadopor uma dasmuitastags condicionais como is_category() is_tag() is_date() is_archive() Emuitomais.Para obter umamelhor compreensãopara o códice http://codex.wordpresspress.org/conditional_tags

"Posts page" is usually an archive of:

• posts of a category
• posts of a tag
• posts of a date ( year, month...)
• posts of main archive

Each one of these can be checked by a one of the many conditional tags like is_category() is_tag() is_date() is_archive() And so many more. To get a better understanding head over to the codex http://codex.wordpress.org/Conditional_Tags

primeiro verifique osblogs relacionados como autor,tag,pós-tipo

 function is_blog () {
        global  $post;
        $posttype = get_post_type($post );
        return ( ((is_archive()) || (is_author()) || (is_category()) || (is_home()) || (is_single()) || (is_tag())) && ( $posttype == 'post')  ) ? true : false ;
  }
 

Agora verifiquee retorne algo que você desejater

 function check_post_type(){
    $postType;
    if (is_blog())
      {
         $postType = 'I am post';
      } else
       {
          $postType = 'I am page';
       };
    return $postType;
  }
 

Use como chefe <?php echo check_post_type();?>

Graças a wesbos

First check the blogs related things like author, tag, post type

function is_blog () {
        global  $post;
        $posttype = get_post_type($post );
        return ( ((is_archive()) || (is_author()) || (is_category()) || (is_home()) || (is_single()) || (is_tag())) && ( $posttype == 'post')  ) ? true : false ;
  }

Now check and return something which you want to have

function check_post_type(){
    $postType;
    if (is_blog())
      {
         $postType = 'I am post';
      } else
       {
          $postType = 'I am page';
       };
    return $postType;
  }

Use it like Boss <?php echo check_post_type();?>

Thanks to Wes Bos

tl; dr

caso a . Não hánecessidade de determinar dentro do arquivo demodeloprincipal (index.php)porque é omodelopadrãoparaele ^[1] .

caseb . Para determiná-lo dentro de ummodelo depágina (ex:page.php),basta verificar assim:

TL;DR

Case A. There is no need to determine it inside the main template file (index.php) because it is the default template for it^[1].

Case B. To determine it inside a page template (ex: page.php), simply check it like so:

get_option( 'page_for_posts' ) == get_the_ID()

Details

I literally went digging the source-code^[2] of it just to be able to know how wordpress does the checking of the value. It turns out, it is using the statement get_option( 'page_for_posts' ) to know the post ID of the selected value of the Posts page.

So yeah, for this purpose, there is no such official checker function that is similar to is_front_page().

As long as you know the ID of the page that you've selected then you can use it for the checking process.
