<form id="form-input-wrapper" action='test.php'>
//form items..
//form items..
<button class="btn btn-primary" type="submit" value="old">first button.</button>
<button class="btn btn-primary" type="submit" value="new">second button</button>
</form>
My question is how to distinquish which button the user clicks in my test.php
page? 我的问题是如何区分用户在
test.php
页面中点击的按钮?
You need to add the name
attribute to your buttons 您需要将
name
属性添加到按钮
<button class="btn btn-primary" type="submit" name="old" value="old">first button.</button>
<button class="btn btn-primary" type="submit" name="new" value="new">second button</button>
The php code to use would look like: 要使用的PHP代码如下所示:
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
//something posted
if (isset($_POST['old'])) {
//old
} elseif (isset($_POST['new']){
//new
}
}

Use button name tag and check them in php: 使用按钮名称标签并在php中检查它们:
<button name="subject1" type="submit" value="HTML">HTML</button>
<button name="subject2" type="submit" value="CSS">CSS</button>
And in php: 在PHP中:
<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
if ( isset($_POST['subject1']) ) {
// first button is clicked
} elseif ( isset($_POST['subject2']) ) {
//second button is clicked
}
}
?>
