How to insert php variable into Wordpress shortcode?
I am setting up custom fields in Wordpress to be able to enter ASIN number from amazon and go through the shortcode I have in my template file.
In my custom field I am using Name: asin and Value: (whatever ASIN # I want to add)
This is what I have in my template file:
<?php $asin = get_post_meta( $post->ID, 'asin', true); ?>
<?php echo $asin ?>
<?php echo do_shortcode( '[scrapeazon asin="B002P4SMHM" width="650" height="400" border="false" country="us")]' );?>
I am trying to put the $ asin variable in the scrapeazon shortcode I have, something like this:
<?php echo do_shortcode( '[scrapeazon asin="<?php echo $asin ?" width="650" height="400" border="false" country="us")]' );?>
But it doesn't work, no ideas?

How about this approach?
function my_shortcode_function( $attributes ) {
global $post;
// manage attributes
$a = shortcode_atts( array(
'foo' => 'something',
'bar' => 'something else',
), $attributes );
// do sth with the custom field
$asin = get_post_meta( $post->ID, 'asin', true);
}
add_shortcode('my_shortcode', 'my_shortcode_function');
So don't try to get a custom value in the template. Just handle it in the shortcode function. Through the $ post global declared variable it should work. Yes, the global ist is not very clean. But this is wordpress ...
