How to show other content (such as an ad) after every “X” number of posts

问题

I have Wordpress website and I want to implement Adsense ads into it.

I have 30 posts per page so i want to show ads after every 7 posts, how can I do this? Currently I am using this method for 3 ads in 10 posts, and after 10 posts no ads showing:

<center><?php if( $wp_query->current_post == 1 ) : ?>

Adsense Code Here 
<?php elseif( $wp_query->current_post == 3 ) : ?>

Adsense Code Here
<?php elseif( $wp_query->current_post == 7 ) : ?>

Adsense Code Here
<?php endif; ?></center>

I want to show ads after every 7 posts, is that possible in one code line ?

回答1:

You just need to put one condition here :-

if( ($wp_query->current_post) % 7 == 0 ):

 Adsense Code Here

endif;

By this you will get 0 as reminder after every post count which is multiple of 7 like 7, 14, 21 etc.

回答2:

You need to use the modulus (or "mod") operator % to get the remainder of value x divided by value y i.e. x % y = remainder. e.g. 4 % 3 = 1 because 4 divided by 3 gives a remainder of 1.

Your code should be:

<?php if( ($wp_query->current_post % 7) == 1  ) : ?>

    Adsense Code Here

<?php endif; ?>

How this works:

You want to display the ad after every 7 posts, so you need to use 3 as the y i.e. the value to divide by. This will give the results:

    1st post:    1 % 7 = 1
    2nd post:    2 % 7 = 2
    3rd post:    3 % 7 = 3
    [...]
    6th post:    6 % 7 = 0
    7th post:    7 % 7 = 1
    8th post:    8 % 7 = 2
    [...]
    14th post:  14 % 7 = 1
    etc.

As you want to start after the first ad, then you want to check for a remainder value of 1.

Tip:

Off topic, but the <center> HTML tag has been deprecated so you shouldn't use it any more. use the CSS style text-align:center on the container element instead.
