Consejo rápido para ver todas las variables de WP Post, que pueden ser útiles para el desarrollo y la depuración en WordPress.

En el método previamente cubierto de ver todas las variables de consulta de WP, mostramos todas las variables de Post en detalle usando la función PHP var_dump(). La salida tiene este aspecto:


object(WP_Post)#165 (24) { 
	["ID"]                    =&gt; int(2) 
	["post_author"]           =&gt; string(1) "1" 
	["post_date"]             =&gt; string(19) "2011-08-21 23:31:47" 
	["post_date_gmt"]         =&gt; string(19) "2011-08-22 06:31:47" 
	["post_content"]          =&gt; string(0) "" 
	["post_title"]            =&gt; string(4) "Example Post" 
	["post_excerpt"]          =&gt; string(0) "" 
	["post_status"]           =&gt; string(7) "publish" 
	["comment_status"]        =&gt; string(4) "open" 
	["ping_status"]           =&gt; string(6) "closed" 
	["post_password"]         =&gt; string(0) "" 
	["post_name"]             =&gt; string(4) "example-post" 
	["to_ping"]               =&gt; string(0) "" 
	["pinged"]                =&gt; string(0) "" 
	["post_modified"]         =&gt; string(19) "2021-01-20 22:11:53" 
	["post_modified_gmt"]     =&gt; string(19) "2021-01-21 05:11:53" 
	["post_content_filtered"] =&gt; string(0) "" 
	["post_parent"]           =&gt; int(0) 
	["guid"]                  =&gt; string(32) "http://example.com/wp/?page_id=2" 
	["menu_order"]            =&gt; int(0) 
	["post_type"]             =&gt; string(4) "page" 
	["post_mime_type"]        =&gt; string(0) "" 
	["comment_count"]         =&gt; string(1) "0" 
	["filter"]                =&gt; string(3) "raw" 
}

object(WP_Post)#165 (24) {

["ID"] => int(2)

["post_author"] => string(1) "1"

["post_date"] => string(19) "2011-08-21 23:31:47"

["post_date_gmt"] => string(19) "2011-08-22 06:31:47"

["post_content"] => string(0) ""

["post_title"] => string(4) "Example Post"

["post_excerpt"] => string(0) ""

["post_status"] => string(7) "publish"

["comment_status"] => string(4) "open"

["ping_status"] => string(6) "closed"

["post_password"] => string(0) ""

["post_name"] => string(4) "example-post"

["to_ping"] => string(0) ""

["pinged"] => string(0) ""

["post_modified"] => string(19) "2021-01-20 22:11:53"

["post_modified_gmt"] => string(19) "2021-01-21 05:11:53"

["post_content_filtered"] => string(0) ""

["post_parent"] => int(0)

["guid"] => string(32) "http://example.com/wp/?page_id=2"

["menu_order"] => int(0)

["post_type"] => string(4) "page"

["post_mime_type"] => string(0) ""

["comment_count"] => string(1) "0"

["filter"] => string(3) "raw"

}

Como puedes ver, además del nombre y el valor de cada variable, var_dump() también incluye el tipo, como «string» o «int». Si no necesitas la información del tipo, puedes simplificar los resultados usando var_export() de PHP, así:


echo var_export($GLOBALS['post'], TRUE);

echo var_export($GLOBALS['post'], TRUE);

Cuando se incluya en su plantilla de temas, ese fragmento producirá una versión simplificada de los resultados devueltos con var_dump(). Para ilustrarlo, aquí está la salida variable para la misma página usada en el ejemplo anterior:


WP_Post::__set_state(
	array( 
		'ID'                      =&gt; 2, 
		'post_author'             =&gt; '1', 
		'post_date'               =&gt; '2021-01-21 23:31:47', 
		'post_date_gmt'           =&gt; '2021-01-22 06:31:47', 
		'post_content'            =&gt; '', 
		'post_title'              =&gt; 'Example Post', 
		'post_excerpt'            =&gt; '', 
		'post_status'             =&gt; 'publish', 
		'comment_status'          =&gt; 'open', 
		'ping_status'             =&gt; 'closed', 
		'post_password'           =&gt; '', 
		'post_name'               =&gt; 'example-post', 
		'to_ping'                 =&gt; '', 'pinged' =&gt; '', 
		'post_modified'           =&gt; '2021-01-20 22:11:53', 
		'post_modified_gmt'       =&gt; '2021-01-21 05:11:53', 
		'post_content_filtered'   =&gt; '', 
		'post_parent'             =&gt; 0, 
		'guid'                    =&gt; 'http://example.com/wp/?page_id=2', 
		'menu_order'              =&gt; 0, 
		'post_type'               =&gt; 'page', 
		'post_mime_type'          =&gt; '', 
		'comment_count'           =&gt; '0', 
		'filter'                  =&gt; 'raw', 
	)
)

WP_Post::__set_state(

array(

'ID' => 2,

'post_author' => '1',

'post_date' => '2021-01-21 23:31:47',

'post_date_gmt' => '2021-01-22 06:31:47',

'post_content' => '',

'post_title' => 'Example Post',

'post_excerpt' => '',

'post_status' => 'publish',

'comment_status' => 'open',

'ping_status' => 'closed',

'post_password' => '',

'post_name' => 'example-post',

'to_ping' => '', 'pinged' => '',

'post_modified' => '2021-01-20 22:11:53',

'post_modified_gmt' => '2021-01-21 05:11:53',

'post_content_filtered' => '',

'post_parent' => 0,

'guid' => 'http://example.com/wp/?page_id=2',

'menu_order' => 0,

'post_type' => 'page',

'post_mime_type' => '',

'comment_count' => '0',

'filter' => 'raw',

)

Además, he aquí una forma de implementar la técnica de visualización-variable a través del archivo functions.php del tema:


// View all WP Post variables
function wpmix_display_globals($content) {
	return $content . var_export($GLOBALS['post'], TRUE);
}
add_filter('the_content', 'wpmix_display_globals');

// View all WP Post variables

function wpmix_display_globals($content) {

return $content . var_export($GLOBALS['post'], TRUE);

}

add_filter('the_content', 'wpmix_display_globals');

Por supuesto, esto se puede afinar utilizando las etiquetas de la plantilla de WP, como las etiquetas condicionales que filtran por tipo de mensaje, categoría y demás.
