在向我的公司发送电子邮件之前，我一直在努力使此表格有效。它不会验证表单，只要有人点击提交就会发送它。没有验证，我不知道该怎么做。
这是一些形式

为了让您的PHP读取表单数据，需要执行一些操作。首先，正如Waygood建议的那样，最好将$ _POST值更改为在传递的变量名称周围加上单引号。
//For example:
$_POST[address];
// Should change to:
$_POST['address']; //Notice the single quotes around the word address
其次，正如John所回答的那样， html表单中没有提及提交的值，您需要在表单中添加隐藏的输入（标记之间的任何位置），其值为1，使您的第一个语句成立，以便执行其余的PHP代码。
<!-- Put this input tag anywhere between your opening and closing form tags in your html -->
<form method="POST" action="your_submission_page.php">
<input type="hidden" name="submitted" value="1" />
</form>
最后，良好做法通知用户表单中的所有错误，以便他们在提交表单之前不会遇到错误。你应该做的是构建一个动态的错误消息数组，检查是否有任何错误，然后全部显示。
<?php
// Create a dynamic array for the error messages and validate everything before sending them back to the form that shows them
// Here is a sample of your code with the dynamic array built in
$error_msgs = array ();
$error = 0; //Error flag
if ($_POST['cwage2']){
$cwage2 = $_POST['cwage2'];
} else {
$error_msgs[] = "Please enter wage earned, or type N/A";
$errors++; //Flag to let the code know that there are errors, used in every case
}
if ($_POST['cstart2']){
$cstart2 = $_POST['cstart2'];
} else {
$error_msgs[] = "Please enter date started, or type N/A";
$errors++; //Flag to let the code know that there are errors, used in every case
}
// Finally at the end, check to see if there are any errors and display them all
if ($errors > 0) {
//Display the amount of errors first
echo "There were " . $errors . " errors in your submission, please correct them.<br/>";
//Then display your error array
foreach ($error_msgs as &$msg) {
echo $msg . "<br/>";
}
} else {
// Add code here to submit the form however you'd like
}
?>
答案 1 :(得分：1)
我没有看到名为submitted的表单字段，如果没有它，您的PHP验证代码将不会被触发。尝试更改：
if ($_POST['submitted']==1) {
更像这样的通用：
if ('POST' === $_SERVER['REQUEST_METHOD']) {
答案 2 :(得分：1)
OK @KibaHeitfield
更改对数组元素的引用：
$_POST[first_name]
为：
$_POST['first_name']
答案 3 :(得分：1)
如果没有其他的
则没有否则{ if（$ errormsg）{//如果已经有错误，请添加下一个错误 $ errormsg = $ errormsg; }否则{
}
}
$ errormsg = $ errormsg;没有任何意义。
答案 4 :(得分：0)
或者你可以这样检查
if($_POST){
//form is posted do your work here
}
答案 5 :(得分：0)
您似乎无法显示错误。尝试将其添加到您的PHP代码的脚下：
echo $errormsg; die();
而不是
$errormsg = $errormsg;
让我们知道会发生什么。
答案 6 :(得分：0)
您是否为表单提供了一种方法（“GET”，“POST”）？
