正如Howdy\\u McGee所说，您需要引用单个数据点，而不是整个用户对象。

<?php
// Get the user object: username, email, firstname, lastname, displayname, and user ID 
$current_user = wp_get_current_user();
// Get other user meta, such as phone number
// (you\'ll have to check what meta_key you\'re using for info like this)
$current_user_meta = get_user_meta($current_user->ID);
?>
$zoho.salesiq.ready=function()
{
  $zoho.salesiq.visitor.name("<?php echo $current_user->display_name; ?>");
  $zoho.salesiq.visitor.email("<?php echo $current_user->user_email; ?>"); 
  $zoho.salesiq.visitor.contactnumber("<?php echo $current_user_meta->phone; ?>");
}
