How use Dynamic hyperlink on each wordpress post?

You need to create a custom metabox on post edit screen, here’s a good tutorial on how to do that.

The tutorial will allow you to have another field on your Post Edit Screen called ‘Get Deals‘

After you follow that tutorial, replace

• ‘smashing_post_class’ with ‘get_deals_link’
• ‘Post Class’ with ‘Get Deals’
• ‘Add a custom CSS class, which will be applied to WordPress’ post class.’ with ‘Get Deals Link

then print your button something like this

<a href="<?php echo get_post_meta( $post->ID, 'get_deals_link', true );?>"
class="button">Get Deal</a>

I hope this helped you.
