Question

I ve written this piece of code, which outputs the profile_display_fields for the $USER:

$appearance = profile_display_fields($USER->id);
        if (empty($appearance)) {
            //Do nothing
        } else {
            foreach ($appearance as $c) {
            $custom .=  <a href=  .$CFG->wwwroot. /course/view.php?id= .$c->id.  > .$c->fullname. </a> ;
            }
        }

Here is the function I m using:

function profile_display_fields($userid) {
    global $CFG, $USER;

    if ($categories = get_records_select( user_info_category ,   ,  sortorder ASC )) {
        foreach ($categories as $category) {
            if ($fields = get_records_select( user_info_field , "categoryid=$category->id",  sortorder ASC )) {
                foreach ($fields as $field) {
                    require_once($CFG->dirroot. /user/profile/field/ .$field->datatype. /field.class.php );
                    $newfield =  profile_field_ .$field->datatype;
                    $formfield = new $newfield($field->id, $userid);
                    if ($formfield->is_visible() and !$formfield->is_empty()) {
                        print_row(s($formfield->field->name. : ), $formfield->display_data());
                    }
                }
            }
        }
    }
}

What I m looking to do is try some var_dumps to output the correct data.

However can anyone help me identify the variables?

Answer 1

In your function you are not returning any value but above that in your code, you have assigned a variable to this function:

$appearance = profile_display_fields($USER->id);

You need to return some variable/data from the function and that is the one to be var dumped.

I suppose you are using the print_row to print the data, not returning the response to be used out of the function.
