Meta field link in shortcodes WordPress
- SOLVED
I'm working with a meta field on a custom template for showing my users a image with a download link to files for the post. I'm trying to achieve this by adding shortcodes in the template and it's almost working.
I added the post meta field value to my template like this:
<?php
// Get custom post meta field values
$link = get_post_meta($post->ID, 'last_ned_filer', true);
?>
and tried to echo the field to the download image url in the shortcode:
function download_files() {
return '<a href="<?php echo $link; ?"><img src="http://mediesjef.no/wp-content/uploads/2011/05/last-ned.png" width="590" height="138" /></a>';
}
add_shortcode('download_files', 'download_files');
But that didn't work.
Do you have any ideas how I can get my link from the meta field to the image?

It looks as if you're never running the shortcode in your template. You'll need to do something like this in your template -
<?php
$link = get_post_meta($post->ID, 'last_ned_filer', true);
echo do_shortcode('[download_files]$link[/download_files]');
?>
Your function should be something like
function download_files( $atts, $content = null ) {
return '<a href="' . $content . '"><img src="http://mediesjef.no/wp-content/uploads/2011/05/last-ned.png" width="590" height="138" /></a>';
}
add_shortcode('download_files', 'download_files');

Hi, Caroline!
I did ran the shortcode in my template, and with the shortcode function you gave me I was able to solve my problem. I used your function and added this to my template:
<?php echo do_shortcode(do_shortcode("[private][download_files]$link [/download_files][/private]")); ?>
Perfect!
Thanks

function download_files() {
global $post;
$link = get_post_meta($post->ID, 'last_ned_filer', true);
return '<a href="<?php echo $link; ?"><img src="http://mediesjef.no/wp-content/uploads/2011/05/last-ned.png" width="590" height="138" /></a>';
}
add_shortcode('download_files', 'download_files');
That should do it.

The problem you were having was that the variables you were using were not in the same scope with each other. You have to make the global variable $post available inside the download_files function. Then get the download link. And you do all this inside the shortcode function.

Try this:
function download_files() {
global $post;
$link = get_post_meta($post->ID, 'last_ned_filer', true);
return '<a href="<?php echo $link; ?"><img src="http://mediesjef.no/wp-content/uploads/2011/05/last-ned.png" width="590" height="138" /></a>';
}
add_shortcode('download_files', 'download_files');
