WordPress Knowledge Base:

1. How to call a single post in wordpress template?

Answer:
Wordpress function: get_post($post_id,$output);
$post_id = id of post to get content
$output = OBJECT- default an object
ARRAY_A-returns an associative array of filed names to values
ARRAY_N- returns numeric array of field values

Example 1:
$postId  = 1;
$data = get_post($postId);
$postTitle = $data->post_title;
$postContent = $data->post_content;

Example 2:
$postId  = 1;
$data = get_post($postId,ARRAY_A);
$postTitle = $data-[‘post_title’];
$postContent = $data[‘post_content’];

Returned Fields are:

ID (integer) The post ID
post_author (integer) The post author’s ID
post_date (string) The datetime of the post (YYYY-MM-DD HH:MM:SS)
post_date_gmt (string) The GMT datetime of the post (YYYY-MM-DD HH:MM:SS)
post_content (string) The post’s contents
post_title (string) The post’s title
post_category (integer) The post category’s ID. Note that this will always be 0 (zero) from wordpress 2.1 onwards. To determine a post’s category or categories, use get_the_category().
post_excerpt (string) The post excerpt
post_status (string) The post status (publish|pending|draft|private|static|object|attachment|inherit|future|trash)
comment_status (string) The comment status (open|closed|registered_only)
ping_status (string) The pingback/trackback status (open|closed)
post_password (string) The post password
post_name (string) The post’s URL slug
to_ping (string) URLs to be pinged
pinged (string) URLs already pinged
post_modified (string) The last modified datetime of the post (YYYY-MM-DD HH:MM:SS)

post_content_filtered (string)
post_parent (integer) The parent post’s ID (for attachments, etc)
guid (string) A link to the post. Note: One cannot rely upon the GUID to be the permalink (as it previously was in pre-2.5), Nor can you expect it to be a valid link to the post. It’s merely a unique identifier, which so happens to be a link to the post at present.
menu_order (integer)
post_type (string) (post|page|attachment)
post_mime_type (string) Mime Type (for attachments, etc)
comment_count (integer) Number of comments
