早上好/下午好，
有人可以向我解释为什么我一直得到一个;
Warning: Missing argument 4 for renderForm(), called in /home/***/public_html/new.php
这是我正在使用的HTML / PHP代码;
<?php
/*
NEW.PHP
Allows user to create a new entry in the database
*/
// creates the new record form
// since this form is used multiple times in this file, I have made it a function that is easily reusable
function renderForm($date, $home, $time, $away, $city, $error)
{
?>

{
renderForm('','','');
}

我试图在这里搜索并没有修复谷歌。有人可以帮我吗？这应该是添加新事件的表单。但是由于这些错误，我无法使其发挥作用。提前感谢您提供的任何帮助。
原始部分已完成。谢谢你的所有答案。但现在我提交后它给了我这个错误，不确定它是否与我编辑的内容有关：
renderForm(null,null,null,null,null,null);
再次感谢你。
答案 0 :(得分：0)
renderForm('','','');代码底部缺少第四个参数。
答案 1 :(得分：0)
您的功能如下：
function renderForm($date, $home, $time, $away, $city, $error){}
你需要将六个总参数传递给函数，
因此，您必须为每个
填充函数调用renderForm(null,null,null,null,null,null);
或者您可以使用''示例中显示的空字符串。但是必须为每个论点传递一些东西。
