Question

I have a form with many form elements that are not allways populated with data, depending on type of product. If I want to print one row – record from mysql db, I want to avoid print column with empty container for data or if I put “%” sign in it. Does anyone has an idea how to do that? Examples are welcome!

Answer 1

You can just check against null or a blank string to see if the column is empty and use strpos to see if ‘%’ appears in it. Only print the column data if the conditions are satisfied:

<?php if (!is_null($row['column']) && $row['column'] != '' && false === strpos($row['column'], '%')) : ?>
    <?php echo $row['column']; ?>
<?php endif; ?>

Or in raw php:

if (!is_null($row['column']) && $row['column'] != '' && false === strpos($row['column'], '%')) {
    echo $row['column'];
}
