尝试将表单变量传递给生成多个页面的脚本时，我遇到了问题。php从表单传递的SESSION变量
我的表单使用$ _POST将以下脚本提供的县名和语言作为2个单独的字段。该脚本在查询被硬编码时运行，而在通过$ _POST传递变量时用于page = 1 results.php页面。然而，后来的页面松动$ _POST变量，我知道这个问题的解决方案涉及$ _SESSION命令，但我不能得到这个工作:(。现在实际上没有结果显示，虽然参数传递给这些功能。
这里是我的代码
<?php
$_SESSION['county']=$_POST['county'];
$_SESSION['language']=$_POST['language'];
$speak=$_POST['language'];
$area=$_POST['county']
?>
<table class="bda" width="100%" align = "center"><tr><td class="hrak">Open test db file on lcn</td></tr></table>
<?php
$conn = connect();
/*******************************************************************************************

*******************************************************************************************/
$area=$_POST['county'];
$speak=$_POST['language'];
$showrecs = 20;
$pagerange = 10;
$page = @$_GET["page"];
if (!isset($page)) $page = 1;
select();
mysql_close($conn);
?>
<table class="bda" width="100%"><tr><td class="hrak">Powered by MySQL</td></tr></table>
</body>
</html>
<?php

<?php function select()
{

global $page;
$res = sql_select();
$count = sql_getrecordcount();
if ($count % $showrecs != 0) {
$pagecount = intval($count/$showrecs) + 1;
}
else {
$pagecount = intval($count/$showrecs);
}
$startrec = $showrecs * ($page - 1);
if ($startrec < $count) {mysql_data_seek($res, $startrec);}
$reccount = min($showrecs * $page, $count);
?>
<table class="bd" border="0" cellspacing="1" cellpadding="4" width="100%" align = "center">

我知道代码工作，而无需使用$ _ POST来传递参数，但我不能让它使用多个结果页（results.php？页工作= n）。我错过了什么？

大家好，我用过session_start（）;没有任何结果。对不起，我错过了我的代码，但在发布后发现了错误。 – bobfelstead
