Help with Custom fields showing in dropdown

Hello there,

I have my site here: Snowboarder2 over Rocky Mountains Colorado Flag T-Shirt | ActiveState Designs and on the right hand side you’ll see a dropdown menu with the style of shirt available. That dropdown is being called in from customfields titled: “buy_now1”, “buy_now2”, etc. Is it possible to add some PHP code to my single_body.php code to basically not have a style in the dropdown if the custom field doesn’t exist for that posts?

Let me try to setup a scenario: Say for a style shirt, I don’t have American Apparel available. Well since American Apparel is tied to buy_now2. Is it possible to have code that says, if custom field buy_now2 exists then show in dropdown?

Hope that helps, I have my dropdown code here:

                <span class="affili_prod"><?php _e('Select T-Shirt Style:','wpShop');?></span>
                <form name="apparel"> 
                    <p align="center"> 
                        <select name="menu"> 
                        <option selected>Choose Apparel:</option> 
                        <option value="<?php get_custom_field('buy_now1', TRUE); ?>">Standard</option> 
                        <option value="<?php get_custom_field('buy_now2', TRUE); ?>">American Apparel | +$4</option> 
                        <option value="<?php get_custom_field('buy_now3', TRUE); ?>">Standard Long-Sleeve | +$3</option> 
                        <option value="<?php get_custom_field('buy_now4', TRUE); ?>">Women's T-Shirt</option> 
                        <option value="<?php get_custom_field('buy_now5', TRUE); ?>">Kid's T-Shirt | -$1</option> 
                        <option value="<?php get_custom_field('buy_now6', TRUE); ?>">Kid's Long-Sleeve | +$2</option> 
                        </select> 
                        <input class="buy_button" type="button" onClick="location=document.apparel.menu.options[document.apparel.menu.selectedIndex].value;">
                    </p> 
                    </br>
                </form> 
                
				<input type="hidden" id="amount" name="amount" value="<?php echo $value[0];?>"/>	
                <!--Disable BuyNow from template
                <input type="hidden" name="buy_now" value="<?php get_custom_field('buy_now', TRUE); ?>" />
                <!--end Disable BuyNow from template-->
				<input type="hidden" name="currency_code" value="<?php echo $OPTION['wps_currency_code']; ?>" />
				
				<?php 
				//has the user remembered to use the image_thumb custom field?
				if(strlen(get_custom_field('image_thumb', FALSE))>0) { ?>
					<input type="hidden" name="image_thumb" value="<?php get_custom_field('image_thumb', TRUE); ?>" />
				<?php } 
				//he did!? 
				else { 
				// get attachment
				$image_thumb = my_attachment_image(0, 'full', 'alt="' . $post->post_title . '"','return');
				?>
					<input type="hidden" name="image_thumb" value="<?php echo $image_thumb[img_path]; ?>" />
				<?php } ?>
				
				<input type="hidden" name="add" value="1" />
				
				<!--Disable BuyNow from template
                <div class="shopform_btn buy_now">
                	<a href="<?php get_custom_field('buy_now', TRUE); ?>" <?php if($OPTION['wps_affili_newTab']) { ?> title="<?php _e('Opens is new tab','wpShop'); ?>" target="_blank"<?php } ?>><?php _e('Buy Now','wpShop'); ?></a>
				</div>
                <!--end Disable BuyNow from template-->

Is this a possibility? Anyone know what direction I should begin?

Basically I just need a snippet of code that say, if custom field “name” equals true, then show “name” in dropdown menu. If that makes sense.

Thanks

Can anyone shed some light on this? I am really needing to get this working to save tons of time!

Thanks,
