AkiiNote PHP HTML 多個按鈕

PHP with HTML

Multiple Buttons on a Form

from：http://stackoverflow.com/a/4120694/4777620

先做兩個按鈕
method 可以改成用get 來看看是不是正確

<form action='' method='post'>
  <button type='submit' name='reset'>Clear</button>
  <button type='submit' name='submit'>Submit</button>
</form>

PHP 提交之後

可以用以下的方法來接住

if(isset($_POST['reset'])) { /* ...clear and reset stuff... */ }
else if(isset($_POST['submit']) { /* ...submit stuff... */ }

以下是另一種方法

<form action='' method='post'>
  <button name='submit' value='0'>Clear</button>
  <button name='submit' value='1'>Submit</button>
  <button name='submit' value='2'>Something Else</button>
</form>

PHP 提交之後

if($_POST['submit']==0)      { /* ...clear and reset stuff... */ }
else if($_POST['submit']==1) { /* ...submit stuff... */ }
else if($_POST['submit']==2) { /* ...do something else... */ }
