如何在 codeigniter 中的 foreach 中多次覆盖 set_message？

Question

    foreach($all_fields as $row){

                        $datatype = $this->sys_model->get_table_data_by_datatype_id('datatype',$row['datatype_id']);
                        $msg = $this->sys_model->get_validation_message_by_datatype_id('validation_message',$row['datatype_id']);

                              if($datatype[0]['datatype'] == 'email'){

                                 $this->form_validation->set_rules($row['field_name'],$row['field_name'], 'required|trim|xss_clean|valid_email');
                                 $this->form_validation->set_message('required',$msg[0]['validation_msg']);
                              }
                              elseif($datatype[0]['datatype'] == 'number'){
                                 $this->form_validation->set_rules($row['field_name'],$row['field_name'], 'required|numeric');
                                 $this->form_validation->set_message('required',$msg[0]['validation_msg']);
                              }else{
                                  $this->form_validation->set_rules($row['field_name'],$row['field_name'], 'required');
                                  $this->form_validation->set_message('required',$msg[0]['validation_msg']);
                              }

                     }

我想根据数据类型从后端动态设置验证消息，但它对所有字段采用相同的消息.. 如何根据数据类型为所有字段设置不同的消息？

Answer 1

为每个数据类型创建一个回调函数

function validate_string($str)
{

    if(condition) )
    {

        return true;

    }
    else
    {
        $this->form_validation->set_message('validate_string', 'The %s your custom error message');
        return false;
    }

} 

$this->form_validation->set_rules('field1', 'label1', 'validate_string');
$this->form_validation->set_rules('field2', 'label2', 'validate_string');
$this->form_validation->set_rules('field3', 'label3', 'validate_string');
$this->form_validation->set_rules('field4', 'label4', 'validate_string');
