Question

这是我的表格

<form name='manual' method='POST' action='manual.php' onsubmit=\"return validateForm()\">

<input type='hidden' name = 'serial_no' value=2 > 

<input type='hidden' name = 'batch' value='' > 

<input type='hidden' name = 'course' value='' >

<input type='hidden' name = 'schedule_id' value=''>

<input type='text'  id='topic' name = 'topic'> 

<input type='text' id='start_date' name = 'start_date' >

<input type='text'  id='end_date' onclick=\"cal();\" name='end_date'>

<input type='submit' name = 'Add'  value='Add'> 

</form>

当我提交表格时

我得到了这个结果：

Array ( [serial_no] => 2 [batch] => [course] => [schedule_id] => [topic] => hai [Add] => Add )

我没有获得start_date和end_date值

任何人都可以解释为什么这两个字段值没有传递。

这是我的代码..

Answer 1

您的start_date和end_date缺少“value”属性。

表单未传递整个字段值
