How to get hyperlink in wordpress php? - php

Question

I am building a website and i have this issue :
I am working on a template and i did some modification. So the front page have some boxes which shows deals and buttons.
As you can see there are buttons called "See Deals"
Each box is a post so when i create a post then each box created automatically . I want that when i put a link on post then it will automatically set behind that "See Deals" button. I mean i want that this "See deal" button take the url from a link which i put in this post.
I wrote this code for boxes :
<div class="price_row_grid">
<div class="price_for_grid floatleft">
<?php theme_create_btn('no', 'price'); ?>
</div>
<div class="floatright vendor_for_grid">
<?php if ($price_meta == 'admin'): ?>
<?php $author_id = $post->post_author; ?>
<a class="admin" href="<?php echo get_author_posts_url($author_id) ?>" title="<?php the_author_meta('display_name', $author_id); ?>">
<?php echo get_avatar($author_id, '22'); ?>
</a>
<?php elseif ($price_meta == 'store'): ?>
<div class="brand_logo_small">
<?php WPSM_Postfilters::re_show_brand_tax('logo'); //show brand logo?>
</div>
<?php endif; ?>
</div>
</div>
<div class="price_row_grid">
<div class="price_for_grid floatleft">
<p class="button">Get Deal</p>
</div>
Now suppose i created a post on wordpress :
Now you can see there i put a dummy link at the end of post "google" now i want that when i put any link there then the box of this post get this link and set behind "Get Deal" button.
