Question

I need to display a page with detailed information about a product. e.g.

 <ul>
 <li>Product: <?php echo $product['Product']['name'] ?></li>
 <li>Features: <?php echo $product['Product']['Features'] ?></li>

etc. (may be 20-30 fields)

The problem is that each product may have or may not have blank fields and I only need to show not empty fields to user.

How to properly filter results to generate and show only

<li>

that contain information?

I see 3 approaches.

1. Many and many of

   <?php if (!empty($product['Product']['name']) echo "<li>Product: ".$product['Product']['name']."</li>"?>
   

2. Add some kind of JS filtering (I don’t know JS so it may be impossible to achieve)

3. Add another column to DB with “li” field description

   (<li>Product:)
   

   and then somehow output only not empty fields with While loop…

Answer 1

Try this:

    echo '<ul>';
    foreach($product['Product'] as $key => $value) {
        if ($product['Product'][$key] != '') {
            if ($key == 'Info') {
                echo '<li>Some text that describes information for a user: ' . $value . '</li>';
            }
            else {
                echo '<li>' . $key . ': ' . $value . '</li>';
            }
        }
    }
    echo '</ul>';
