问题描述
在发送电子邮件给我公司之前，我一直试图使此表格生效。它不会验证表单，只要有人点击提交就会发送。没有验证发生，我不知道该怎么做。
以下是一些表格
< tr>
< td>< label for =reason3>离开的原因？< / label>< / td>
< td>< input type =textid =reason3name =reason3class =c3>< / td>
< / tr>
< tr>

< / tr>
< tr>
< td>< label for =maywe>我们可以联系上面列出的雇主吗？< br>
如果不是，请指出您不希望我们联系：< / label>< / td>
< td>< input type =textid =maywename =mayweclass =c3>< / td>

解决方案
有几件事情需要按顺序发生让你的PHP阅读表单数据。首先，正如Waygood所建议的那样，将$ _POST值更改为传入变量名称的单引号是一个好主意。
//例如：
$ _POST [address];
//应改为：
$ _POST ['address'];第二，如约翰所回答的那样，没有任何参考文献到 HTML表单中传递的提交的值，您需要在表单中添加一个隐藏的输入（在您的标签之间的任意位置），其值为1你的第一个声明是真实的，以便让其他php代码执行。 <！ - 将此输入标记放置在任意位置在您的html中打开和关闭窗体标签之间 - >
< form method =POSTaction =your_submission_page.php>
< input type =hiddenname =submittedvalue =1/>
< / form>
最后，最佳做法通知使用者所有的错误在表格中，以便在能够提交表格之前不会出现错误。你应该做的是建立一个错误消息的动态数组，检查是否有任何错误，然后显示全部。
<？php
//为错误消息创建一个动态数组，然后将其发回给显示它们的表单
//以下是您的代码示例动态数组内置
$ error_msgs = array（）;
$ error = 0; //错误标志
if（$ _POST ['cwage2']）{
$ cwage2 = $ _POST ['cwage2'];
} else {
$ error_msgs [] =请输入赚取的工资，或输入N / A;
$ errors ++; //标记让代码知道有错误，在每种情况下使用
}
if（$ _POST ['cstart2']）{
$ cstart2 = $ _POST [ 'cstart2'];
} else {
$ error_msgs [] =请输入开始日期，或输入N / A;
$ errors ++; //标记让代码知道有错误，在每种情况下使用
}
//最后在最后检查是否有任何错误并将它们全部显示
if（$ errors> 0）{
//首先显示错误的数量
echoThere were。 $错误。 在您提交的错误中，请更正它们。< br />;
//然后显示错误数组
foreach（$ error_msgs as& $ msg）{
echo $ msg。 <峰; br /> 中;
} else {
//在这里添加代码以提交表单，但是你想要
}

I have been trying to make this form validate before sending an email to my company. It will not validate the form, it will just send it whenever someone clicks submit. No validation is happening, I don't know what to do about this.
Here is a little of the form
<tr>
<td><label for="reason3">Reason for Leaving?</label></td>
<td><input type="text" id="reason3" name="reason3" class="c3"></td>
</tr>
<tr>
<td colspan="2">
<hr size="1.5" color="#000000" noshade></td>
</tr>
<tr>
<td><label for="maywe">May we contact the employers listed above?<br>
If not, indicate which you do not wish us to contact:</label></td>
<td><input type="text" id="maywe" name="maywe" class="c3"></td>
</tr>
<tr>
<td><label for="additional">Any additonal information you would like us to<br>
consider when reviewing your application?</label></td>
<td><input type="text" id="additional" name="additional" class="c3"></td>
</tr>
<tr>
<td colspan="2">
<hr size="1.5" color="#000000" noshade></td>
</tr>
<tr>
<td colspan="2">
<div class="c2">
<hr size="1.5" color="#000000" noshade>
The above information is true and complete to the best of my knowledge. Should I become<br>
employed by <a href="http://www.creativeurethanes.com/">Creative Urethanes, Inc.,</a> any false statements on this application may be<br>
considered sufficient cause for dismissal.<br>
I understand that filling out this application does not indicate that there are necessarily any<br>
vacant positions at this time, nor does it in any way obligate this Company.<br>

解决方案 There are a few things that need to happen in order for your PHP to read the form data. First, as Waygood suggested, it is a good idea to change your $_POST values to have single quotes around the passed variable name.
//For example:
$_POST[address];
// Should change to:
$_POST['address']; //Notice the single quotes around the word address
Secondly, as answered by John, there is no reference to the passed submitted value in your html form, you'll want to add a hidden input in your form (anywhere between your tags) that holds the value of 1 to make your first statement true in order for the rest of your php code to execute.
<!-- 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>
Finally, it's good practice to notify the user of ALL of the errors in the form so that they don't experience error after error before being able to submit the form. What you should be doing is building a dynamic array of error messages, checking to see if there are any errors and then displaying them all.
<?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
}
?>
