今天，我正在处理客户邮件表格，然后几次收到此通知。请任何人为我提供解决此问题的正确方法。

<?php
    if(isset($_REQUEST['Submit']))
    {
    $name = $_REQUEST['name'];
    $phone = $_REQUEST['phone'];
    $email = $_REQUEST['email'];

    $weburl = $_REQUEST['weburl'];
    $url =$_SERVER['HTTP_REFERER'];
    $ip=$_SERVER['REMOTE_ADDR'];
    $sub="Enquiry Mail from : ".$_REQUEST['email'];
    $from=$_REQUEST['email'];   
    }
    function getUserIpAddr()
    {
        if (!empty($_SERVER['HTTP_CLIENT_IP'])) //if from shared

            return $_SERVER['HTTP_CLIENT_IP'];

    }
    ?>

注意：未定义的变量：第59行的quote.php中的味精

注意：未定义索引：第10行上的weburl quote.php

我发现了上述问题。 请任何人帮助我解决此问题。

在连接之前，您需要像$msg这样在代码$msg = ''的开头进行定义... 

$msg.="----------------------------------------------------------------\n";

您正在此处将其串联起来，但之前没有在任何地方定义它...

对于isset，您需要在使用数组值之前检查它是否已设置... 

if(isset( $_REQUEST['weburl'])){
 $weburl = $_REQUEST['weburl'];
}

答案 1 :(得分：0)

很简单。

  1. 在函数启动时将msg变量声明为$ msg ='';
  2. 数据不在$ _REQUEST ['weburl']中，您可以使用if语句和isset内置函数处理它。

我正在更新代码，您可以复制并粘贴它。

    <?php
    if(isset($_REQUEST['Submit']))
    {
    $name = $_REQUEST['name'];
    $phone = $_REQUEST['phone'];
    $email = $_REQUEST['email'];
    $movingfrom = $_REQUEST['movingfrom'];
    $movingto= $_REQUEST['movingto'];
    $describe = $_REQUEST['describe'];

   if(isset($_REQUEST['weburl']) && $_REQUEST['weburl']!=''){
       $weburl = $_REQUEST['weburl'];
   }else{
       $weburl = '';
   }


    $url =$_SERVER['HTTP_REFERER'];
    $ip=$_SERVER['REMOTE_ADDR'];
    $sub="Enquiry Mail from : ".$_REQUEST['email'];
    $from=$_REQUEST['email'];   
    }
    function getUserIpAddr()
    {
        if (!empty($_SERVER['HTTP_CLIENT_IP'])) //if from shared
        {
            return $_SERVER['HTTP_CLIENT_IP'];
        }
        else if (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //if from a proxy
        {
            return $_SERVER['HTTP_X_FORWARDED_FOR'];
        }
        else
        {
            return $_SERVER['REMOTE_ADDR'];
        }
    }
    if(($name == NULL) &&( $name== ""))
    {
    echo "Name is Mandatory  <br>";
    }
    if(($email == NULL) &&($email == ""))
    {
    echo "Email is Mandatory  <br>";
    }
    /*
    if(!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$", $email)) {

    }

    if(($movingto == NULL) &&($movingto == ""))

    $msg="";


    if(  (($email != NULL) && ($email != "")) && (($name != NULL) && ($name != "")) && (($phone != NULL) && ($phone != "")) && (($movingfrom != NULL) && ($movingfrom != ""))&& (($movingto != NULL) && ($movingto != "")) )

像这样修改您的代码，它将对您有用。

<?php
    if(isset($_REQUEST['Submit']))
    {
    $name = $_REQUEST['name'];
    $phone = $_REQUEST['phone'];
    $email = $_REQUEST['email'];
    $movingfrom = $_REQUEST['movingfrom'];
    $movingto= $_REQUEST['movingto'];
    $describe = $_REQUEST['describe'];
    if(isset($_REQUEST['weburl']))
      $weburl = $_REQUEST['weburl'];
    $url =$_SERVER['HTTP_REFERER'];
    $ip=$_SERVER['REMOTE_ADDR'];
    $sub="Enquiry Mail from : ".$_REQUEST['email'];
    $from=$_REQUEST['email'];   
    }
    function getUserIpAddr()
    {
        if (!empty($_SERVER['HTTP_CLIENT_IP'])) //if from shared
        {
            return $_SERVER['HTTP_CLIENT_IP'];
        }
        else if (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //if from a proxy
        {
            return $_SERVER['HTTP_X_FORWARDED_FOR'];
        }
        else

对所有请求变量使用Isset，这样您就永远不会得到任何通知，因为有些值没有到来。

希望它会为您提供帮助。

  1. 您需要初始化$msg变量。
    2.   
  2. 为isset编写$_REQUEST['weburl']条件。.
    3.   

您更新后的代码，例如：

<?php
        if(isset($_REQUEST['Submit']))
        {
    $msg='';
        $name = $_REQUEST['name'];
        $phone = $_REQUEST['phone'];
        $email = $_REQUEST['email'];
        $movingfrom = $_REQUEST['movingfrom'];
        $movingto= $_REQUEST['movingto'];
        $describe = $_REQUEST['describe'];
    if(isset($_REQUEST['weburl'])){
            $weburl = $_REQUEST['weburl'];
    }else{
     $weburl ='';
    }
        $url =$_SERVER['HTTP_REFERER'];
        $ip=$_SERVER['REMOTE_ADDR'];
        $sub="Enquiry Mail from : ".$_REQUEST['email'];
        $from=$_REQUEST['email'];   
        }
        function getUserIpAddr()
        {
            if (!empty($_SERVER['HTTP_CLIENT_IP'])) //if from shared
            {
                return $_SERVER['HTTP_CLIENT_IP'];
            }
            else if (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //if from a proxy
