Question

在我的代码中，我试图从一个php获取变量的值到另一个。在这个php文件中，我通过url从其他一些php文件中获取值。

我得到了其他部分内部的所有值但不在内部，如果变量meeting_id和pemail没有在数据库中存储任何东西，并且所有其他字段都完美地存储值。我哪里错了？

<?php 
if (isset($_POST['send'])) { 

    $pemail = $_POST['e'];
    $meeting_id = $_POST['mid']; 
    $date = $_POST["dat"];
    if ($date=="val1") {
        $d1 = 'Yes';
    } 
    else {
        $d1='No';
    }
    if ($date=="val2") {
        $d2 = 'Yes';
    }
    else {
        $d2='No';
    }
    $location = $_POST["location"];
    if ($location=="val1") {
        $l1 = 'Yes';
    }
    else {
        $l1='No';
    }
    if ($location=="val2") {
        $l2 = 'Yes';
    }
    else {
        $l2='No';
    }
    $check_list1 = $_POST['check_list1'];
    if ($check_list1 != 'yes') {
        $check_list1 = 'No';
    }
    $check_list2 = $_POST['check_list2'];
    if ($check_list2 != 'yes') {
        $check_list2 = 'No';
    }
    $host='mysql5.000webhost.com';
    $uname='admin';
    $pwd='*****';

    $db="meeting";
    $con = mysql_connect($host,$uname,$pwd) or die("connection failed");
    mysql_select_db($db,$con) or die("db selection failed");
    $flag['code']=0;
    if($r=mysql_query("insert into meeting.response (meeting_id, Email, 
     DAT1, DAT2, Location1, Location2, Travel, Hotel) 
     values('$meeting_id','$pemail','$d1','$d2','$l1','$l2','$check_list1',
     '$check_list2') ",$con))

        {

            $flag['code']=1;
            echo"hi";
        }
    print(json_encode($flag));
    mysql_close($con);

    ?> 
    Your response was sent

Answer 1

您使用POST而不是GET传递变量。为了奖励，我清理了你的代码以便于阅读。

在您的代码中更改此内容：

Your response was sent
<?php 
} else {
$top=$_GET['t']; 
$dat1=$_GET['d1']; 
$tim1=$_GET['t1']; 
$dat2=$_GET['d2']; 
$tim2=$_GET['t2']; 
$loc1=$_GET['l1']; 
$loc2=$_GET['l2'];
$mid=$_GET['id']; 
$e=$_GET['pemail']; 
?>

对此：

Your response was sent
<?php 
} else {
$top=$_POST['t'].'<br>'; 
$dat1=$_POST['d1'].'<br>'; 
$tim1=$_POST['t1'].'<br>'; 
$dat2=$_POST['d2'].'<br>'; 
$tim2=$_POST['t2'].'<br>'; 
$loc1=$_POST['l1'].'<br>'; 
$loc2=$_POST['l2'].'<br>';
$mid=$_POST['id'].'<br>'; 
$e=$_POST['pemail']; 
?>

Answer 2

您说您是通过网址发送的，而不是通过帖子操作发送的。所以$ _POST为空，使用$ _GET作为url值。通过显示以下值来检查发送的内容：print_r（$ _ GET）和print_r（$ _ POST）。

PHP没有使用GET获取if语句中的值
