显示自定义字段值

Question

I'm trying to display custom fields on my site , but unable to return any values in the front-end.

First I added this function to functions.php :

function get_custom_field($custom_field) {
    global $post;
    $custom_field = get_post_meta($post ->ID, custom_field, true) ;
    return $custom_field ,
}

In my page.php I added this :

<?php if ( function_exists('get_custom_field') ) {
    get_custom_field('distance', true) ;  
} ?>

The "distance" field is the custom field that I created and want to be displayed.

Any direction would be great.

Answer 1

Did you miss the $ symbol in the custom_field? Fix:

$custom_field = get_post_meta($post->ID, $custom_field, true);

in the calling function you need to use only one parameter. As can i see, you have only one param in the function, the code:

<?php if ( function_exists('get_custom_field') ) {
    get_custom_field('distance') ;  } ?>
