为了继续,必须填写表格字段'room_number','pos_token','banquet_token'中的任何一个。这是要求,我编写了这段代码并最终与代码的其他部分发生冲突,但根本不起作用。
$room_number = $this->input->post('room_number');
$pos_token = $this->input->post('pos_token');
$banquet_token = $this->input->post('banquet_token');
if(isset ($room_number) && strlen($room_number) && ($pos_token) && strlen($pos_token) && ($banquet_token) && strlen($banquet_token) ) {
return true;
}
else {
return true;
}

您需要为输入字段设置规则
$this->form_validation->set_rules('username', 'Username', 'required');
if ($this->form_validation->run() == FALSE)
{
//run your code on success here
}
else
{
//run your code on failure here
}

您需要在条件失败时返回false
if(isset ($room_number) && strlen($room_number) && ($pos_token) && strlen($pos_token) && ($banquet_token) && strlen($banquet_token) ) {
return true;
}
else {
return false;
}
根据您的情况,您需要查看OR
条件
if( ( isset ($room_number) && strlen($room_number)) ||
( isset ($pos_token) && strlen($pos_token)) ||
( isset ($banquet_token) && strlen($banquet_token))
) {

只需在if语句中使用||
OR运算符即可。如果测试失败,则返回false
。
$room_number = $this->input->post('room_number');
$pos_token = $this->input->post('pos_token');
$banquet_token = $this->input->post('banquet_token');
if(!empty($room_number) || !empty($pos_token) || !empty($banquet_token))
return true;
else
return false;

$room_number = $this->input->post('room_number');
$pos_token = $this->input->post('pos_token');
$banquet_token = $this->input->post('banquet_token');
if($room_number=="" || $pos_token=="" || $banquet_token=="")
return true;
else
return false;
