为什么 php 不适用于我的表单？ [关闭]

Question

在向我的公司发送电子邮件之前，我一直在尝试验证此表单。它不会验证表单，它只会在有人点击提交时发送。没有验证发生，我不知道该怎么做。

这是一个小表格

<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>

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>

Answer 1

为了让您的 PHP 读取表单数据，需要做一些事情。首先，正如 Waygood 建议的那样，最好将您的 $_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，在您的 html 表单中没有对传递的 submitted 值的引用，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何位置）保存值 1 以使您的第一条语句为真，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，良好的做法通知用户表单中的所有错误，这样他们就不会在提交表单之前遇到一个又一个错误。您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，然后将它们全部显示出来。

<?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

    }

?>

Answer 2

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。尝试改变：

if ($_POST['submitted']==1) {

像这样更通用的东西：

if ('POST' === $_SERVER['REQUEST_METHOD']) {

Answer 3

好的@KibaHeitfield

更改对数组元素的引用：

$_POST[first_name]

到：

$_POST['first_name']

Answer 4

1. 没有if可以跟随else

   否则{ if ($errormsg){ //如果已经有错误，添加下一个错误 $错误消息 = $错误消息； }其他{

   }
   

   }

2. $errormsg = $errormsg;没有任何意义。

3. Errormsg 已分配但从未使用过。使用 echo $errormsg;
4. $_POST[first_name] 应该是 $_POST['first_name']
5. 而不是 $_POST['submitted'] 使用 if($_POST['field89'] == 'Submit')
6. 您为什么不尝试一个小表单并在它开始工作时展开。

Answer 5

或者你可以简单地检查这种方式

if($_POST){
 //form is posted do your work here
}

Answer 6

您似乎无法显示错误。尝试将此添加到您的 php 代码的脚下：

echo $errormsg; die();

而不是

$errormsg = $errormsg;

让我们知道会发生什么。

Answer 7

您是否为表单提供了方法（“GET”、“POST”）？
