用于代码编写器的数字验证检查 - float Number validation check for codeigniter

float Number validation check for codeigniter

我在这里输入税收字段，但当我输入2.5,0.5等值而不是整数时，它会产生错误。这是我的代码验证，输入浮点数的任何想法

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;
  }
</code>

将is_natural从验证规则中删除并替换为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]将应用于numeric

来自codeigniter文档:

is_natural如果表单元素包含非自然数:0、1、2、3等，则返回FALSE

显然，像2.5、0.5这样的值不是自然数，因此它们将无法通过验证。您可以使用回调并在使用floatval() PHP函数解析值后返回值。

希望有帮助!

你可以试试:

function _set_rules()
{
  $this->form_validation>set_rules('pst','PST','trim|required|
  numeric|max_length[4]|callback_max_pst');
  $this->form_validation->set_rules('gst','GST','trim|required|
  numeric|max_length[4]|callback_max_gst');
}
function max_pst($value) {
    $var = explode(".", $value);
    if (strpbrk($value, '-') && strlen($value) > 1) {
        $this->form_validation->set_message('max_pst', '%s accepts only 
        positive values');
        return false;
    }
    if ($var[1] > 99) {
        $this->form_validation->set_message('max_pst', 'Enter value in 
        proper format');
        return false;
    } else {
        return true;
    }
}

希望这段代码能帮助到你....:)
