Making values in meta box conditional?

Unsure if the title is fitting, let me break it down. I am adding a jquery slider to my theme, using a meta box with 5 different text fields for pasting the image url. So far so good.

But what I want to achieve is to make each text field in the meta box, so if no image url is added it won't show in the slider as an image, or broken image as the url is not there.

So how do I make the values in the meta box conditional? Here's the code I suspect needs to tweaking:

<div id="slider" class="nivoSlider">

           

<img src="<?php $my_meta = get_post_meta($post->ID,'_my_meta',TRUE); echo $my_meta['urltwo']; ?>" alt="" />

                

<img src="<?php $my_meta = get_post_meta($post->ID,'_my_meta',TRUE); echo $my_meta['urlthree']; ?>" alt="" />

                

<img src="<?php $my_meta = get_post_meta($post->ID,'_my_meta',TRUE); echo $my_meta['urlfour']; ?>" alt="" />

                

<img src="<?php $my_meta = get_post_meta($post->ID,'_my_meta',TRUE); echo $my_meta['urlfive']; ?>" alt="" /> 

            

</div>

<?php } ?>
    
            
    

    
</div>


    What I am doing here is making sure the value even exists before making an image with it.

    Hello,

    simply change the queries to your meta values to include an 'if' statement before them:


    
<?php if ( get_post_meta( $post->ID,'_my_meta', TRUE ) && $my_meta['urltwo'] != '' ) {
    
    $my_meta = get_post_meta($post->ID,'_my_meta',TRUE); 
    
    ?>
    
    <img src="<?php echo $my_meta['urltwo']; ?>" alt="" />
    
<?php } ?>


    * also keep the variable out of the img src attribute

    Reformat all your img tags like this and let me know how it went. Cheers!

    How about this?

    <div id="slider" class="nivoSlider">
    

    
<?php 
    
	$meta = get_post_meta($post->ID,'_my_meta',TRUE);
    
	
    
	if ( $meta) {
    

    
		$fields = array ( 'urltwo', 'urlthree', 'urlfour', 'urlfive' );
    
		
    
		foreach( $fields as $field ) {
    
	
    
			if( !empty( $meta[$field] ) ) {
    
				echo '<img src="'.$meta[$field].'" alt="" />';
    
			}
    
		}
    
	}
    
?>
    
</div>
