  • 0

I´d like to use foreach to echo all images-path, but when a variable is empty $bild_5 than shouldn’t display any HTML code around.

My code: 

<html>

<?php

// var
$url    = "http://www.URL/assets/";

$bild_1 = $url . "bild-1.jpg"; 
$bild_2 = $url . "bild-2.jpg"; 
$bild_3 = $url . "bild-3.jpg"; 
$bild_4 = $url . "bild-4.jpg"; 
$bild_5 = ""; 

// array
$bilder = array ("$bild_1", "$bild_2", "$bild_3", "$bild_4", "$bild_5");
?>

<ul>
    <!-- foreach / Template -->
    <?php foreach($bilder as $bild) { ?>    

        <li><img src="<?php echo $bild; ?>"</li>

    <?php } ?>
</ul>

</html>

HTML-OUTPUT

<html>

<ul>                
   <li><img src="http://www.URL/assets/bild-1.jpg"</li>
   <li><img src="http://www.URL/assets/bild-2.jpg"</li>
   <li><img src="http://www.URL/assets/bild-2.jpg"</li>
   <li><img src="http://www.URL/assets/bild-4.jpg"</li>
   <li><img src=""</li>    // Don´t display this HTML code; ( $bild_5 = ""; )
</ul>

</html>

Thanks for your help

    You can use continue to skip

    <?php foreach($bilder as $bild) { ?>   
       <?php if (empty($bild)) continue; ?> 

        <li><img src="<?php echo $bild; ?>"</li>

<?php } ?>

    I would also recommend that you use the alternate syntax for control structures when you mix PHP and HTML. It’s easier to read

    <?php foreach($bilder as $bild) : ?>    

        <li><img src="<?php echo $bild; ?>"</li>

<?php endforeach; ?>
