How the template tags work, in the method just put any template tag inside the Loop and view the results of tag.
Now see the following example views the values of a couple different template tags:
if ( have_posts() ) :
while ( have_posts() ) :
<a href=”<?php the_permalink(); ?>”><?php the_title(); ?></a>
<br />
That you have seen that, your post titles are displayed with links to the permalink for each post and the content of the post is displayed directly below the post title. Tag Parameters Every tag has its different functionality and most of the template tags have parameters that can be added to modify the value returned.
For example, this template tag the_content() template tag has two parameters. The first parameter allows you to set the more link text like that:

<?php the_content( ‘Read more’, false ); ?>

Then your post content will be displayed as normal show in the post, after the adding this parameter <!–more–> tag is found in your post,  The WordPress will automatically add the text Read more, it has the link to the entire blog post. The second parameter determines whether to display the teaser paragraph again when viewing the full post. False value is the default so the teaser will be displayed in both places.


WordPress more tag tag allows you to display a defined teaser from the full post on your website. Let’s suppose, on your home page you could display the first paragraph of a post, full blog post only show when a visitor clicks the link to view the full post. For accomplish this, put <!–more–> in your content in HTML view where you want to break to happen. There is a button to insert a More tag into the visual editor.

There is another option that you can also send multiple parameters to any template tag that supports it.
For example, another template tag the_title() in this tag three parameters can passed: $before, $after, and $echo. In this tag the following  code sets $after and $before parameters to wrap the post title with h1 tags:

<?php the_title( ‘<h1>’, ‘</h1>’ ); ?>

In the WordPress source code you can also view the actual function. The post template functions are located in  wp-includes/post-template.php. For a quick search for function the_title() will lead you to the exact function for the the_title() tag. The Codex for a detailed description you can also use of the template tag which you are working with, so in this case http://codex.wordpress.org/Template_Tags/the_title visit this title.
