Show variable on frontend based on if checkbox is checked - php

Question

I hope I can explain this right but the image should make it clear (hopefully).
In the admin side of my site, I have different fields for products, but I do not want the fields shown to the frontend user if the show checkbox isn't checked. As seen in my image below.
Now my issue I am not getting is should I have a row name for every checkbox or can I use just one like show.
simplified can I use something like this
<div class="form-group">
<label class="col-md-3">Sales Price</label>
<div class="col-md-8">
<input type="text" name="price" value="<?php echo $row['price']; ?>" class="form-control" />
</div> <!-- /.col -->
<input type="checkbox" value="1" <?php echo ($row['show'] == 1) ? 'checked="checked"' : ''; ?> name="show">
</div> <!-- /.form-group -->
or do I have to use something like this
<div class="form-group">
<label class="col-md-3">Sales Price</label>
<div class="col-md-8">
<input type="text" name="price" value="<?php echo $row['price']; ?>" class="form-control" />
</div> <!-- /.col -->
<input type="checkbox" value="1" <?php echo ($row['showprice'] == 1) ? 'checked="checked"' : ''; ?> name="showprice">
</div> <!-- /.form-group -->
Here is what I am after using an image.
As for making the content show on the frontend Here is the code for that. This is set up now to NOT show if the data is missing. (I haven't set it up to show about the checkboxes until I figure out what to use)
<?php if (isset($model) && !empty($model)) : ?>
<li class="element element-text">
<strong>Model #: </strong>
<?php echo $model;?>
</li>
<?php endif; ?>
I thought about using something like this, but again I am not sure if I can use a single checkbox (show) for all the variables.
<div style="display:<?= ($offer === 1) ? 'block' : 'none'; ?>"></div>
Again, I hope I explained this good enough and any help would be greatly appreciated.
