Wordpress - Using custom fields to call relevant NivoSlider

I am currently looking to use a different NivoSlider on each post outside of the post content area, so I set up a custom field ('nivo_number') where I can enter the Nivo Slider number and call it within the template using

So, currently I have:

<?php echo do_shortcode;?>("<?php echo get_post_meta($post->ID, 'nivo_number', true); ?>")<?php ; ?>

However this just outputs the following text on the site

do_shortcode("[nivoslider id='123']")

Can anyon开发者_Go百科e help? If it doesn't make sense I will try and explain futher.

Thankyou

I think the second echo is not necessary, I don't know if that is the problem, why don't you try:

<?php echo do_shortcode(get_post_meta($post->ID, 'nivo_number', true)); ?>

or

<?php
    $nivo_number = get_post_meta($post->ID, 'nivo_number', true);
    echo do_shortcode($nivo_number);
?>

BTW what's exactly the value of the custom field? is it [nivoslider id='123'] or just 123?

Just noticed an error in your syntax. Here echo do_shortcode;?>("<?php echo you're closing ?> before (, that might be the reason the code isn't interpreted.
