wrap text around custom fields array

  • I’m using this code here to grab all my custom fields from a post for use in an gallery array.

    function:

    //  Get all custom fields attached to a page
if ( !function_exists('base_get_all_custom_fields') ) {
function base_get_all_custom_fields()
{
    global $post;
    $custom_fields = get_post_custom($post->ID);
    $hidden_field = '_';
    foreach( $custom_fields as $key => $value ){
        if( !empty($value) ) {
            $pos = strpos($key, $hidden_field);
            if( $pos !== false && $pos == 0 ) {
                unset($custom_fields[$key]);
            }
        }
    }
    return $custom_fields;
}
}

    single.php:

    // Get all custom fields attached to this post and store them in an array
$custom_fields = base_get_all_custom_fields();
if( !empty($custom_fields) ) {
print_r($custom_fields);
}

    It works, but outputs text like this around the custom post: Array ( [photo1] => Array ( [0] =>

    Is there a way to customise what you wrap before & after a custom field output, and remove the array text? I ‘m not a php expert.

    What I’m trying to achieve is

    {image : 'https://website.com/slides/photo1.jpg'},
{image : 'https://website.com/slides/photo2.jpg'},
{image : 'https://website.com/slides/photo3.jpg'},

    so I need to wrap {image : ‘ before and ‘}, after the link.

    I can sort of do it with single queries but the array system would be better

    {image : '<?php echo $custom_fields['photo1'][0]; ?>'},
{image : '<?php echo $custom_fields['photo2'][0]; ?>'},
{image : '<?php echo $custom_fields['photo3'][0]; ?>'},

  • The print_r() function just dumps out the contents of a variable. To format as you showed in your sample, you will need to have a foreach loop to process each link:

    // Get all custom fields attached to this post and store them in an array
$custom_fields = base_get_all_custom_fields();
if( !empty($custom_fields) ) {
   $sep = '';
   foreach ($custom_fields as $key => $value) {
      echo "$sep{image : '$value'};
      $sep = ",\n";
   }
}
