I was wondering if anyone knew how I could use an if/then statement with PHP to say that if a custom field, such as product sale_price is empty, then display only the price, else display price and sale_price fields.
I know how to do the if/then statements in PHP but I am unsure of what value to specify for the empty field. Here is an example I am working with.
<?php if ($record['sale_price'] == "empty"): ?>
Price: $<?php echo $record['price'] ?><br/>
<?php else: ?>
Price: $<?php echo $record['price'] ?><br/>
Sale Price: $<?php echo $record['sale_price'] ?><br/>
<?php endif ?>
Thanks,
Brian

Looks pretty close, generally you can just specify "" to match an empty fields. So you could write it like this:
or another way (maybe simpler) would be like this:
With != to mean "sale price is not empty". Hope that helps! :)
<?php if ($record['sale_price'] == ""): ?>
Price: $<?php echo $record['price'] ?><br/>
<?php else: ?>
Price: $<?php echo $record['price'] ?><br/>
Sale Price: $<?php echo $record['sale_price'] ?><br/>
<?php endif ?>or another way (maybe simpler) would be like this:
Price: $<?php echo $record['price'] ?><br/>
<?php if ($record['sale_price'] != ""): ?>
Sale Price: $<?php echo $record['sale_price'] ?><br/>
<?php endif ?>With != to mean "sale price is not empty". Hope that helps! :)
