消息：implode（）：在codeigniter中传递的参数无效

Question

code:

$item_des = implode(',',$this->input->post('item_des'));
$item_cost = implode(',',$this->input->post('item_cost'));
$service_cost = implode(',',$this->input->post('service_cost'));
$total_cost = implode(',',$this->input->post('total_cost'));

$data = array(
            'item_des' => $item_des,
            'item_cost' => $item_cost,
            'service_tax' => $service_cost,
            'total_cost' => $total_cost,
            );

            print_r($data);
$query = $this->db->insert('table_name',$data);

In this code I have a form where I am using jquery/ajax for inserting form value but when I am using implode function it raise an error message and i.e.

Message: implode(): Invalid arguments passed

So, How can I fix this issue ?Please help me.

Thank You

You can convert $a to array to make sure you are always working with arrays when using implode

implode(',', (array) $a);

Where,

$a=$this->input->post('item_des');

and so on for the other cases. Just try this it will surely run !
