hello,
I have a custom field (dropdown) on User cloumn.
I want set default value and readonly it by plugin.
my plugin codes:

<?php
defined('_JEXEC') or die;

use Joomla\CMS\Plugin\CMSPlugin;
use Joomla\CMS\Factory;

class PlgSystemHikaShopCustomize extends CMSPlugin
{
    public function onHikashopBeforeDisplayView(&$view)
    {
        // Only modify the user registration form view
        if ($view->getName() !== 'user' || $view->getLayout() !== 'form') {
            return;
        }

        $user = Factory::getUser();

        // Check if the logged-in user is in the 'Teacher' group (group ID 15)
        if (in_array(15, $user->getAuthorisedGroups())) {
            // Ensure Hikashop helper is loaded
            if (!class_exists('hikashopFieldClass')) {
                if (!include_once(JPATH_ADMINISTRATOR . '/components/com_hikashop/helpers/helper.php')) {
                    return;
                }
            }
			

$class = hikashop_get('class.field');
$field = $class->getField('teacher_name', 'user');
$lenew = new stdClass();
$lenew->value = "azur";
$lenew->disabled = 0;
$field->field_value['bleue'] = $lenew;
$class->addValue($field->field_id, 'bleue', 'azur', 0);

Hi,

First, the code:

            // Ensure Hikashop helper is loaded
            if (!class_exists('hikashopFieldClass')) {
                if (!include_once(JPATH_ADMINISTRATOR . '/components/com_hikashop/helpers/helper.php')) {
                    return;
                }
            }
should not do anything. The event onHikashopBeforeDisplayView is only called by the main helper file of HikaShop. So if your method is called, HikaShop is already loaded. Thus, you can remove it.

Second, in onHikashopBeforeDisplayView the field data is already loaded in the view and the view will use the data already loaded. So there is no need to load the field data, and you need instead to update the field data in the view.

So, you want to use something like this:
$lenew = new stdClass();
$lenew->value = "azur";
$lenew->disabled = 0;
$view->extraFields['user']['teacher_name']->field_value['bleue'] = $lenew;

thank you,
I updated plugin codes by:

<?php
defined('_JEXEC') or die;

use Joomla\CMS\Plugin\CMSPlugin;
use Joomla\CMS\Factory;

class PlgSystemHikaShopCustomize extends CMSPlugin
{
    public function onHikashopBeforeDisplayView(&$view)
    {
        // Only modify the user registration form view
        if ($view->getName() !== 'user' || $view->getLayout() !== 'form') {
            return;
        }

        $user = Factory::getUser();

        // Check if the logged-in user is in the 'Teacher' group (group ID 15)
        if (in_array(15, $user->getAuthorisedGroups())) {
           
			$class = hikashop_get('class.field');
			$field = $class->getField('teacher_name', 'user');
			$lenew = new stdClass();
			$lenew->value = $user->id;
			$lenew->disabled = 0;
			$view->extraFields['user']['teacher_name']->field_value[$user->id] = $lenew;

        }
    }
}

But not affect on field atall (not set value and disable)

Hi,

Well, you need to do some debugging.
Do a var_dump of $view->extraFields and check that the code goes past your user group check. That should be a good start.

class PlgSystemHikaShopCustomize extends CMSPlugin
{
    public function onHikashopBeforeDisplayView(&$view)
    {
        // Only modify the user registration form view
        if ($view->getName() !== 'user' || $view->getLayout() !== 'form') {
            return;
        }

        $user = Factory::getUser();

        // Check if the logged-in user is in the 'Teacher' group (group ID 15)
        if (in_array(15, $user->getAuthorisedGroups())) {
            // Ensure Hikashop helper is loaded
            if (!class_exists('hikashopFieldClass')) {
                if (!include_once(JPATH_ADMINISTRATOR . '/components/com_hikashop/helpers/helper.php')) {

                }
            }

            $fieldClass = hikashop_get('class.field');
            $field = $fieldClass->getField('teacher_name', 'user');

           
            

            // Set the field default value to the current user's ID
            $field->field_default = $user->id;

            // Generate the field HTML with the correct number of arguments
            $field->field_html = $fieldClass->display($field, $user->id, 'data[user][teacher_name]');

            // Modify the field HTML to disable the field
            if (!empty($field->field_html)) {
                // Disable the select field
                $field->field_html = str_replace('<select', '<select disabled="disabled"', $field->field_html);
            }

            // Update the field in the view
            $view->fields['user']['teacher_name'] = $field;

            // Set the value in the form data
            if (isset($view->user)) {
                $view->user->teacher_name = $user->id;
            } else {
                $view->user = new stdClass();
                $view->user->teacher_name = $user->id;
            }
			
			$document = Factory::getDocument();
$script = "
    document.addEventListener('DOMContentLoaded', function() {
        var field = document.querySelector('select[name=\"data[user][teacher_name]\"]');
        if (field) {
            field.disabled = true;
        }
    });
";
$document->addScriptDeclaration($script);

        }
    }
}
