Be in the loop!
Not all plugins provide a way to automatically attach code before or after the post content. Or you might have some other HTML, CSS or JavaScript you’d like to include with every post. Now’s your chance. With In The Loop you can easily add any code you like to your posts and pages, and not have to do any messy edits to your theme files either.
The plugin provides an options panel with two input boxes. One is for content you want to appear before your post, the other for after it. Each box comes with a set of options to control whether to show it on Teasers, Single Posts, Pages, The Feed and whether or not to execute PHP.

In The Loop

Be in the loop! Easily add any HTML, CSS, JavaScript or PHP to the begining or end of a post. Great for when plugins forget to add this ability.

Adds a template tag for use on pages which list posts, and to be used 
within <a href="https://codex.wordpress.org/the_loop" rel="nofollow ugc">The Loop</a>. Outputs 
a date header to split up the post listings. See 
<a href="https://codex.wordpress.org/Template_Tags/the_date" rel="nofollow ugc">the_date() 
template tag docs</a> for usage.

<h3>Known issues / bugs</h3>
Please <a href="http://www.simonwheatley.co.uk/contact-me/" rel="nofollow ugc">report any issues</a> that you find.
<h3>Examples</h3>
To produce something like this:
Heading: March, 2008 
Post: dated 15th March 
Post: dated 28th March 
Post: dated 29th March
Heading: April, 2008 
Post: dated 1st April 
Post: dated 4th April
etc…
Add a date header like this: 
 <?php intermittent_date( 'F Y', '<h3 class="date-header">', '</h3>' ); ?>
To produce something like this:
Heading: 25th March, 2008 
Post: dated 08:00 on 25th March 
Post: dated 11:37 on 25th March 
Post: dated 15:33 on 25th March
Heading: 22th March, 2008 
Post: dated 09:12 on 25th March 
Post: dated 10:16 on 25th March
etc…
Add a date header like this: 
 <?php intermittent_date( 'jS F Y', "<h3 class='date-header'>", "</h3>" ); ?>
It’s up to you to style it with CSS then (although your theme may handle this for you).

Intermittent Date

Adds a template tag for use on pages which list posts, and to be used 
within The Loop. Outputs 
a date header to split up the post listings.
