Different Behaviors Dependent on Form Button Clicks?

本文关键字：表单按钮依赖于 | 更新日期: 2023-09-27

所以，我想将不同的行为绑定到Zend PHP表单上的同一个按钮。下面是我现在的代码示例:

if (isset($_POST['submit'])) {
    $this->_helper->messenger->addSuccess('Are you sure you would like to delete this link? The link and all statistics tied to it will be permanently deleted if you take this option.');
    if (isset($_POST['submit'])) {    
        ...
    }
}

然而，无论我点击多少次提交，这段代码似乎都在继续显示消息。我的问题是

我想做的是可能的吗?
如果我想要的行为无法实现，我该怎么办?

根据您想要执行的操作更改按钮的值。例如，默认情况下将该值设置为1，当提交一次时，动态地将该按钮的值设置为2。现在根据$_POST['submit']的值显示警报或采取行动。

示例代码:

if (isset($_POST['submit'])) {
    if ($_POST['submit'] == 1) {
        //submitted first time
        $this->_helper->messenger->addSuccess('Are you sure you would like to delete this link? The link and all statistics tied to it will be permanently deleted if you take this option.');
    } else if ($_POST['submit'] == 2) {    
        // second time, so take action
        ...
    }
}
