Need Iframe plugin for coupon website

Hello friends, I am running an coupon code website with clipper theme. the problem is to applying iframe on each link is i dont know where to put the code. The following template-functions.php code where the actual affiliate is calling is

<?php
break;

default:
?>
<h3><?php _e(‘Promo:’, ‘appthemes’); ?></h3>
<div class=”couponAndTip”>
<div class=”link-holder”>
(hyper link a)(href=”)<?php echo clpr_get_coupon_out_url( $post ); ?>” id=”coupon-link-<?php echo $post->ID; ?>” class=”coupon-code-link” title=”<?php _e(‘Click to open site’, ‘appthemes’); ?>” target=”_blank” data-rel=”<?php _e(‘Click to Redeem’, ‘appthemes’); ?>”><span><?php _e(‘Click to Redeem’, ‘appthemes’); ?></span>
</div>
</div>
