Question

这个问题一直被问到，但我无法弄清楚为什么我的工作不起作用。我有一个重定向到自己的表单。如果PHP决定提交，则会有成功/失败消息，它会将用户输入显示为默认值并禁用字段：使用phpinfo我可以看到表单正在提交，但第一个条件不起作用。我尝试了几个版本，但没有运气。这很奇怪，因为它发送了电子邮件

具体来说，结果和禁用功能在表单发送后不显示其代码。

<?php
function clean($data) {
    $data = trim(stripslashes(strip_tags($data)));
    return $data;
}
function result(){
    if($sent) echo $result;
}
function disable($field){
    if($sent){
        if($field != null){
            $ret .= $field . '", disabled, placeholder!="';
        }
        $ret .= '", disabled, placeholder!="';
        echo $ret;
    }
}
function option($item){
        $ret = "<option>";
    if($sent){
        if($eventType == $item){
            $ret = "<option selected>";
        }
    }
    $ret .= $item . "</option>";
    echo $ret;
}
if(isset($_POST['name'])){
    $sent = TRUE;
    $result = null;
    $name = $_POST['name'];

Answer 1

if(isset($_POST['name'])){

应该是

if(isset($_POST['submit'])){

Answer 2

您必须将全局变量导入函数范围，例如：

function result(){
    global $sent, $result;
    if($sent) echo $result;
}

..在函数disable（）和option（）中也是如此。
