Php 如何在Yii框架中使用两个itemAlias？

我试图在我的项目中的一个模型中使用两个itemAlias，但当我运行程序时，浏览器上没有显示任何内容。这是我的模型：

public static function itemAlias($type,$code=NULL) {
         $_items = array(
        'Category' => array(
            '1' => 'Administration',
            '2' => 'Faculty',
            '3' => 'Staff',
        ),
        );
                 if (isset($code))
            return isset($_items[$type][$code]) ? $_items[$type][$code] :       false;
       else
        return isset($_items[$type]) ? $_items[$type] : false;
}

public static function itemAlias($type,$code=NULL) {
    $_items = array(
        'Category' => array(
            '1' => 'College President',
            '2' => 'College Director',
            '3' => 'Dean of Student Affairs',
            '4' => 'Guidance Councilor',
            '5' => 'MArketing Head',
            '6' => 'College Registrar',
            '7' => 'College Accountant',
            '8' => 'School Nurse',
            '9' => 'Department Head',
            '10' => 'Department Coordinator',
            '11' => 'Faculty',
            '12' => 'Librarian',
            '13' => 'Property Custodian',
            '14' => 'Utility',
            '15' => 'Guard',
        ),
    );
    if (isset($code))
        return isset($_items[$type][$code]) ? $_items[$type][$code] : false;
    else
        return isset($_items[$type]) ? $_items[$type] : false;
}

这是使用ItemAlias的表单：

有什么问题吗？

很遗憾，我的程序编码错误，可能会使用两个或多个项目别名，您应该将其放在$\u items数组下

public static function itemAlias($type,$code=NULL) {
$_items = array(
    'PositionCategory' => array(
        '1' => 'College President',
        '2' => 'College Director',
        '3' => 'Dean of Student Affairs',
        '4' => 'Guidance Councilor',
        '5' => 'MArketing Head',
        '6' => 'College Registrar',
        '7' => 'College Accountant',
        '8' => 'School Nurse',
        '9' => 'Department Head',
        '10' => 'Department Coordinator',
        '11' => 'Faculty',
        '12' => 'Librarian',
        '13' => 'Property Custodian',
        '14' => 'Utility',
        '15' => 'Guard',
    ),
   'GroupCategory' => array(
        '1' => 'Administration',
        '2' => 'Faculty',
        '3' => 'Staff',
    ),
);
if (isset($code))
    return isset($_items[$type][$code]) ? $_items[$type][$code] : false;
else
    return isset($_items[$type]) ? $_items[$type] : false;
}

我试过了，它解决了我的问题，谢谢大家

public static function itemAlias($type,$code=NULL) {
$_items = array(
    'PositionCategory' => array(
        '1' => 'College President',
        '2' => 'College Director',
        '3' => 'Dean of Student Affairs',
        '4' => 'Guidance Councilor',
        '5' => 'MArketing Head',
        '6' => 'College Registrar',
        '7' => 'College Accountant',
        '8' => 'School Nurse',
        '9' => 'Department Head',
        '10' => 'Department Coordinator',
        '11' => 'Faculty',
        '12' => 'Librarian',
        '13' => 'Property Custodian',
        '14' => 'Utility',
        '15' => 'Guard',
    ),
   'GroupCategory' => array(
        '1' => 'Administration',
        '2' => 'Faculty',
        '3' => 'Staff',
    ),
);
if (isset($code))
    return isset($_items[$type][$code]) ? $_items[$type][$code] : false;
else
    return isset($_items[$type]) ? $_items[$type] : false;
}
