Show if field is not empty - PHP/MySQL

Question

Is there a way I can only show bits of a page if a recordset
has entries in a certain field, automatically hiding the area if
the field is empty. (PHP/MySQL)
To put it in real terms, I have loads of products listed in a
repeating table. If a product has a photo gallery related to it
there is a 1 entered in 'photos' field, it has a video attached
here is a 1 entered in 'videos field and likewise for reviews it
will have a 1 entered in the reviews field.
What I'd like to have is a photo, video and review icon/link
in the 'master table' which only appears in the repeated products
that have a 1 listed in that field and have them not appear at all
when there is a 0 in the field.
Can anyone help me figure it out

ADDT is certainly a great help, as it - among many other
features - will allow you define whatever page element as
"show/hide" based on a query result -- for this it´s using a
so-called "condition builder" which lets you do that without
coding.
However you can achieve the same result without needing to
resort to ADDT -- by using a basic "if" condition that´s
checking the respective table column for having the value "1"
stored, and if so, display the page segment
The following 3 examples should work when replacing the
sample "queryname" with the query name your page is actually using:
<?php if ($row_queryname['photos'] == '1') {?>
display photo icon here
<?php }?>
<?php if ($row_queryname['videos'] == '1') {?>
display video icon here
<?php }?>
<?php if ($row_queryname['reviews'] == '1') {?>
display videos icon here
<?php }?>
