Display Ad every after 3 Posts

问题

I'm trying to display an advertisement every after 3 posts in a wordpress blog. Could you guys check something that's wrong in the code?

See the code here

回答1:

see Make $after_every = 0 and add $after_every++ bottom of while loop

then add one condition

if($after_every%3==0){ Show add}

I think it works.

回答2:

I can't figure out why are you using modulus there. http://php.net/manual/en/language.operators.arithmetic.php

I think that is something you didn't want. The way I usualy do this is:

if( $ad_counter >= 3 ) {
$ad_counter = 0;
echo '<h2 style="color:red;">Advertisement or custom content here</h2>';
}

And you can remove line 12 :)
