用两种形式检查哪个按钮被按下

Question

我的网页中有两个表单，一个有一个字段和一个按钮，另一个有两个字段和一个按钮。

我很难检查按下了哪个表单的按钮，欢迎就如何处理此问题提出任何建议。

<form class="form-inline" action="somewhere.php" method="post">
<div class="form-group">
  <label for="date">Date:</label>
  <input type="text" class="form-control" name="date" id="date" placeholder="abc">
</div>

<button type="submit" class="btn btn-default">Submit</button>
</form>


<form class="form-inline" action="somewhere.php" method="post">
<div class="form-group">
  <label for="date1">Date 1:</label>
  <input type="text" class="form-control" name="date1" id="date1" placeholder="abc>
</div>
<div class="form-group">
  <label for="date2">Date 2:</label>
  <input type="text" class="form-control" name="date2" id="date2" placeholder="abc">
</div>

<button type="submit" class="btn btn-default">Submit</button>
</form>

什么应该检查按下了什么按钮。

$date = $_POST['date'];
$date1 = $_POST['date1'];
$date2 = $_POST['date2'];

if (!empty(date)) {
//do something
}
if (!empty($date1) && !empty($date2)) { 
//do something else
}

Answer 1

首先在按钮中给name属性。

<button type="submit" name="button1" class="btn btn-default">Submit</button>

<button type="submit" name="button2" class="btn btn-default">Submit</button>

现在php边检查按下哪个按钮：

if(isset($_POST['button1']){
  //Do something.
 }
else if(isset($_POST['button2'])
{
 //Do something.
}

Answer 2

HTML

<button type="submit" name="btn1" class="btn btn-default">Submit</button>
<button type="submit" name="btn2" class="btn btn-default">Submit</button>

PHP

if(isset($_POST['btn1']){
  //put code here.
 }else{
    //put code here.
 }
