    A little nested php question:
    I want to retrieve wordpress bookmarks with a certain category:
    <?php wp_list_bookmarks('title_li=&category_name=CUSTOMFIELD-ISSUE'); ?>
    and this category will be set on posts with the custom field ‘issue’:

    <?php
global $wp_query;
$postid = $wp_query->post->ID;
echo get_post_meta($postid, 'issue', true);
?>

    How do I merge these two functions? My php-writing needs work, I know ;O)
    Thanks

    If you are using PHP 5.3 you can get more Javacript-like behaviour with an anonymous function:

    <?php
function outer() {
    $inner=function() {
        echo "test\n";
    };

    $inner();
}

outer();
outer();

inner(); //PHP Fatal error:  Call to undefined function inner()
$inner(); //PHP Fatal error:  Function name must be a string
?>

    Output:

    test
    test

    Not sure I understand your reply Apsira. Anyway, I got there in the end, here is the code I used for any one who’s interested:

    I think Apsira is spamming, but I just can’t tell.

    Can you post the code on pastebin? 🙂
