从我的表单提交页面上什么也得不到(PHP)

Question

我对web开发非常陌生，但我现在有一个想法，我想做一个页面，允许登录的用户报告问题，并将其发送到该用户的电子邮件字段中的任何电子邮件。问题是，当我点击提交按钮时，我只会被带到一个白色的页面，但是似乎没有任何一个php在工作。我在我的页面顶部和页面底部做了一个include_once，它们出现了，所以看起来PHP正在运行，但我什么也得不到。有没有人可以看看这个，并建议为什么它可能不起作用？

谢谢。

这是我的表单所在的页面，看起来一切都在进行中。

<?php
include_once("php_includes/problem_form_email.php"); ?>

  <form action="problem_form_email.php" method="post" name="reportform" id="reportform">
    <div>Full Name: </div>
    <input id="fullname" type="text" maxlength="64">
    <div>Your Email address:</div>
    <input id="tenantemail" type="text" maxlength="88">
    <div>Your Phone number:</div>
    <input id="phonenumber" type="text" maxlength="64">
    <div>House Number or Name:</div>
    <input id="housenumber" type="text" maxlength="64">
    <div>First Line of address:</div>
    <input id="streetname" type="text" maxlength="64">
    <div>City:</div>
    <input id="city" type="text" maxlength="64">
    <div>Your Postcode:</div>
    <input id="postcode" type="text" maxlength="14">
    <div>Type of Problem:</div>
    <select id="typeofproblem">
    <option value="">TYPE OF PROBLEM</option>
<option value="Water">Water</option>
<option value="Decor">Decor(Paintwork, wallpaper etc.)</option>
<option value="Heating">Heating</option>
<option value="Windows">Windows</option>
<option value="Flooring">Flooring</option>
<option value="Kitchen">Kitchen</option>
<option value="Furniture">Furniture</option>
<option value="Roofing">Roofing</option>
    </select>
    <div>Describe your problem (Please be detailed):</div>
    <TEXTAREA style="resize:none; width:300px;" name="probdesc" ROWS=8 COLS=64 onfocus="emptyElement('status')"></textarea>
    <div>How urgent is this problem?:<br> Urgency is to help us filter the most in need cases, please don't abuse it.</div>
    <select id="urgency" onfocus="emptyElement('status')">
    <option value="">Choose an option</option>
<option value="Very Low">Very Low</option>
<option value="Low">Low</option>
<option value="Medium">Medium</option>
<option value="High">High</option>
<option value="Very High">Very High</option>
    </select>

    <div>
    </div>
    <br /><br />
    <input type='submit' value="Report Problem">
  </form>

然后，所有变量都应该转到我的另一个页面，该页面将向用户发送一封电子邮件，然后显示某种成功的HTML。这就是我想我做错了什么的地方。看看..。

我使用了一个模板表单提交页面，并对其进行了更改，模板表单可以在这里找到。http://www.freecontactform.com/email_form.php

我只想澄清一下，这个php页面的HTML部分不会显示在

    // EDIT THE 2 LINES BELOW AS REQUIRED
include_once("php_includes/db_conx.php");
$sql = "SELECT email FROM users WHERE id='$log_id' AND username='$log_username'LIMIT 1";

$email_to = mysqli_query($db_conx, $sql); 
echo "$email_to";
 $email_subject = "MOUSE ACCOUNT - A Tenant has reported a problem";


    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();

    }



    // validation expected data exists

Answer 1

看起来您有很多没有任何name参数的输入，PHP使用这些参数来填充$_GET/$_POST

<input id="fullname" type="text" maxlength="64">

它应该如下所示：

<input id="fullname" name="fullname" type="text" maxlength="64">
                     ^^^^^^^^^^^^^^^

您的脚本中可能会有更多错误，但添加此代码应该会对您有所帮助

您还提到正在填充$log_id和$log_username，但是在哪里调用checkuserlogin.php呢？它是否在db_conx.php中被调用，否则就有问题了。您可能希望打开错误消息以接收消息。

Answer 2

添加名称参数，如Class said和change

<input type='submit' value="Report Problem">

至

<input type="submit" value="Report Problem">

也删除

include_once("php_includes/problem_form_email.php");

你不需要这个，否则你不会关闭php标签

<?php
include_once("php_includes/problem_form_email.php");

将其更改为

<?php
include_once("php_includes/problem_form_email.php"); ?>

Answer 3

好的，我让它显示了一件事，问题是我没有在我的problem_form_email.php中包含checkuserlogin.php，所以我的sql语句不能执行。但现在我只是不断得到下面显示的错误。我没办法让他们停下来，有什么额外的帮助吗？
