雜貨污物多選字段

Question

否使用該功能「多選字段」，這表明，該網站上的問題：

http://www.grocerycrud.com/documentation/options_functions/field_type 

$crud->field_type('fruits','multiselect', 
        array("1" => "banana", "2" => "orange", "3" => "apple")); 

下一步，我試圖從數據庫中提取數據，以取代在上面的公式中的「數組」但失敗了，請指教。

$this->db->select('employeeNumber'); 
$a = $this->db->get('employees')->result(); 
$crud->field_type('firstName', 'multiselect', $a); 

我越來越像結果

Array ([0] => stdClass Object ([employeeNumber] => 1002) 
     [1] => stdClass Object ([employeeNumber] => 1056) 

嗯......如何將它做成這種格式，任何意見？：

array("1" => "banana", "2" => "orange", "3" => "apple")

你需要真正做一個foreach這裏。在我們的例子，你需要做這樣的事情：

$this->db->select('employeeNumber'); 
$results = $this->db->get('employees')->result(); 
$employees_multiselect = array(); 

foreach ($results as $result) { 
    $employees_multiselect[$result->employeeNumber] = $result->employeeNumber; 
} 

$crud->field_type('firstName', 'multiselect', $employees_multiselect); 

，或者如果你有僱主的名字做這樣的事那就更好了：

$this->db->select('employeeNumber, employeeName'); 
$results = $this->db->get('employees')->result(); 
$employees_multiselect = array(); 

foreach ($results as $result) { 
    $employees_multiselect[$result->employeeNumber] = $result->employeeName; 
} 

$crud->field_type('firstName', 'multiselect', $employees_multiselect);
