我是NEW到PHP/HTML/JAVASCRIPT和Stackoverflow等，然而，我与我的表单唯一的障碍是"一个不需要数据的字段"(取决于用户输入)阻止成功提交。当我删除"isset($post[number2])等为例，它工作得很好!我如何包括必要的isset和接受空白条目，以成功提交我的PHP表单请?我希望我已经解释清楚了。很抱歉命名协议，提前感谢。下列代码:
<?php
if(isset($_POST['email'])) {
// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "xxxxxxxxxxxxxxx";
$email_subject = "Register Request";
function died($error) {
// your error code can go here
echo "We are very sorry, but there were error(s) found with the form you submitted. ";
echo "These errors appear below.<br /><br />";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";
die();
}

从你的条件中删除字段，你已经写在//验证期望的数据存在只把那些字段放在这是你真正需要的，你不希望用户留下空白删除其他。希望有帮助
从验证块中删除所有"可选"字段。
如果$_POST['number2']是可选的，排除它
我找到了修复!
我所要做的就是添加....
&& $_POST['name2'] !=""|| (after each entry that may have a blank parameter.)
//Do my PHP code
编码快乐!
直接删除代码
!isset($_POST['name2']) ||
和修改你写
的代码$name2 = $_POST['name2'];
$name2 = isset($_POST['name2'];
现在设置了变量$name2。它仍然可能保持空，因为你把它作为可选的，所以如果你不想发送空值，检查它之前，你下次使用$name2就像
if (!empty($name2)) {
$email_message .= "BSB Number: ".clean_string($name2)."'n";
}
如果你想继续发送空值，如BSB Number: .，你可以跳过if (!empty($name2))条件。
为所有你想用isset()检查的可选字段执行此操作
在单个文件index.php中尝试所有这些代码。
