php - codeigniter 的 float 验证检查

Question

在这里，我以 % 输入税收字段，但是当我输入诸如 2.5,0.5 之类的值而不是整数时，它会产生错误。
这是我的验证代码，任何输入浮点数的想法


function _set_rules()
{
  $this->form_validation->set_rules('pst','PST','trim|required|is_natural|numeric|
   max_length[4]|callback_max_pst');
  $this->form_validation->set_rules('gst','GST','trim|required|is_natural|numeric|
max_length[4]|callback_max_gst');
}
function max_pst()
 {
   if($this->input->post('pst')>100)
    {
      $this->form_validation->set_message('max_pst',' %s Value Should be less than or equals to 100');
return FALSE;
    }
   return TRUE;
  }
function max_gst()
  {
    if($this->input->post('gst')>100)
      {
    $this->form_validation->set_message('max_gst',' %s Value Should be less than or equals to 100');
    return FALSE;
    }
   return TRUE;
  }

Answer 1

删除 is_natural来自验证规则并将其替换为 greater_than[0]和 less_than[100]

function _set_rules()
{
  $this->form_validation>set_rules('pst','PST','trim|required|
  greater_than[0]|less_than[100]|max_length[4]|callback_max_pst');
  $this->form_validation->set_rules('gst','GST','trim|required|
  greater_than[0]|less_than[100]|max_length[4]|callback_max_gst');
}

greater_than[0]将适用 numeric
