How can I limit the characters in this code?
.get_post_meta($post->ID,'smple1',true).
I have tried with the following:
$trim_length = 21; //desired length of text to display
$custom_field = 'smple1';
$value = get_post_meta($post->ID, $custom_field, true);
if ($value) {
echo '.rtrim(substr($value,0,$trim_length)) . ';
}
But I get server error. I must be missing an endif or something?
Many thanks.
