Fetching a users selected custom field value in Joomla 4

[JooN00b]

In Joomla 3 i used an external profile extension and could fetch the value of a custom user field with

Code: Select all

$user = JFactory::getUser();
$valueXYZ = JUserHelper::getProfile($user->id)->field_xyz;

I have now created the corresponding custom user fields in the native Joomla 4 component com_fields and the context com_users.user. I can't seem to find a simple solution lika above so instead i currently have solved it as follows:

Code: Select all

$user = \Joomla\CMS\Factory::getApplication()->getSession()->get('user');
use \Joomla\Component\Fields\Administrator\Helper\FieldsHelper;
if ($user->id != NULL) {
  foreach (FieldsHelper::getFields('com_users.user', $user, 0) as $field) {
            if ($field->name == "field_xyz")
            {
	           $valueXYZ = $field->value;
            }
            
        }
}

It seems way to complicated and to go through 40 field with foreach every time seems inefficient. I do not want to hard code the ID of the specific field in each module/component. By doing so it would be sufficient to use the code

Code: Select all

$user = \Joomla\CMS\Factory::getApplication()->getSession()->get('user');
JModelLegacy::addIncludePath(JPATH_ADMINISTRATOR . '/components/com_fields/models', 'FieldsModel');
$fieldModel = JModelLegacy::getInstance('Field', 'FieldsModel', array('ignore_request' => true));
$value = $fieldModel->getFieldValue(7, $user->id);

What simple solution am I missing?

Welcome to the Joomla forum!

You are right about using the names of custom fields, rather than field ids. Using field names makes the PHP code self documenting. Here is an example with switch and case statements:

Code: Select all

use Joomla\CMS\Factory;
use Joomla\Component\Fields\Administrator\Helper\FieldsHelper;
$customFields 	= FieldsHelper::getFields('com_users.user', Factory::getUser(), true); 
$fieldA		= '';
$fieldB		= '';
$fieldC		= '';
foreach ($customFields as $field)
{
	switch ($field->name)
	{
		 case 'fielda':
			$fieldA	= $field->value;
		 case 'fieldb':
			$fieldB	= $field->value;
		 case 'fieldc':
			$fieldC	= $field->value;			
		default:
	}
}

Thanks for your response and the welcome @Toivo.

Both your solution and mine uses a foreach-loop that I would prefer to avoid.

Each time I use the suggested solution I actually only need one or two values of the 40 custom fields so iterating through all 40 just to for example fetch a single value feels quite ineffective.

Is there any other function that directly fetches the value of a single custom user field that I have missed?

Just found a shorter way using the PHP function array_column(). This example has user custom fields fielda, fieldb and fieldc.

Code: Select all

use Joomla\CMS\Factory;
use Joomla\Component\Fields\Administrator\Helper\FieldsHelper;
$customFields = FieldsHelper::getFields('com_users.user', Factory::getUser(), true); 
$values	      = array_column($customFields, 'value', 'name');
// echo '<div><p>values = ' . print_r($values, true) . '</p></div>';
echo '<p>fielda = ' . $values['fielda']  . '</p>';
echo '<p>fieldb = ' . $values['fieldb']  . '</p>';
echo '<p>fieldc = ' . $values['fieldc']  . '</p>';

It would be interesting to compare the elapsed time of this function and the foreach loop.
