PHP session 变量没有通过成功

Question

我将在 PHP 中首次涉足会议。例如，我想为一个名为 phonemessearch2.php 的页面创建一个 link 来加载该页面并将变量 phon1 设置为 "M"，phon3 为 "L"，phon4 为 "IY"。 amd 匹配 "umatch"。因此我 link 到这个 URL:

phonemessearch2.php?phon1=M&phon3=L&phon4=IY&umatch=umatch

目标页面中的代码如下：

session_set_cookie_params(3600,"/");
session_start();

//submitted form variable definitions

if(isset($_POST['umatch']))
{
    $umatch = $_POST['umatch'];
} else {
    if( !isset($_SESSION['umatch']) )
    {
        $umatch = '';
    } else {
        $umatch = $_SESSION['umatch'];
    }
} 
$_SESSION['umatch'] = $umatch;


if(isset($_POST['phon1']))
{
    $phon1 = $_POST['phon1'];
} else {
    if( !isset($_SESSION['phon1']) )
    {
        $phon1 = '';
    } else {
        $phon1 = $_SESSION['phon1'];
    }
} 
$_SESSION['phon1'] = $phon1;

if(isset($_POST['phon2']))
{
    $phon2 = $_POST['phon2'];
} else {
    if( !isset($_SESSION['phon2']) )
    {
        $phon2 = '';
    } else {
        $phon2 = $_SESSION['phon2'];
    }
} 
$_SESSION['phon2'] = $phon2;

if(isset($_POST['phon3']))
{
    $phon3 = $_POST['phon3'];
} else {
    if( !isset($_SESSION['phon3']) )
    {
        $phon3 = '';
    } else {
        $phon3 = $_SESSION['phon3'];
    }
} 
$_SESSION['phon3'] = $phon3;

if(isset($_POST['phon4']))
{
    $phon4 = $_POST['phon4'];
} else {
    if( !isset($_SESSION['phon4']) )
    {
        $phon4 = '';
    } else {
        $phon4 = $_SESSION['phon4'];
    }
} 
$_SESSION['phon4'] = $phon4;

if(isset($_POST['phon5']))
{
    $phon5 = $_POST['phon5'];
} else {
    if( !isset($_SESSION['phon5']) )
    {
        $phon5 = '';
    } else {
        $phon5 = $_SESSION['phon5'];
    }
}

当页面加载时，它不会合并来自 URL 的变量值。所有的变量都是空白的。我怎样才能让它们坚持下去？

谢谢！

我认为这与您的会话没有任何关系 - URL 中的变量（如 phonemessearch2.php?phon1=M&phon3=L&phon4=IY&umatch=umatch）将在 $_GET 中，而不是 $_POST 中。
