Question

请寻求帮助。我使用以下代码过滤并显示工作正常的结果。我的问题是结果没有传递到第二页，所以页面变成空白没有错误。这是非常新的，所以欢迎所有的帮助。

$num_rec_per_page=2;
$con = mysql_connect("localhost","root","");
if (!$con)
{
    die('Could not connect: ' . mysql_error());
}
mysql_select_db("searchresults") or die("ERROR");

if (!isset($_POST['submit'])) exit();

$vars = array('companyname','location');
$verified = TRUE;
foreach ($vars as $v) {
    if (!isset($_POST[$v]) || empty($_POST[$v])) {
       $verified = FALSE;
    }
}
if (!$verified) {
    echo "Sorry no results found, please enter your search";
    exit();
}

// isset function is also used in checking for the existence of data in $_POST
if (isset($_POST["companyname"]) && $_POST["companyname"] != '') {
    $companyname = mysql_real_escape_string($_POST["companyname"]);
    $companyname = " AND (companyname LIKE '%$companyname%')";
}
if (isset($_POST["location"]) && $_POST["location"] != '') {
    $location = mysql_real_escape_string($_POST["location"]);
    $location = " AND (location LIKE '%$location%')";
}

if (isset($_GET["page"])) { $page  = $_GET["page"]; } else { $page=1; };

$start_from = ($page-1) * $num_rec_per_page;

$sql = "SELECT *  FROM reviewsandtips WHERE member_id > 0". $companyname . $location . "LIMIT $start_from, $num_rec_per_page";

$sql_result = mysql_query($sql) or die (mysql_error());

// now echo the code for the table heading
if (mysql_num_rows($sql_result)>0) {

    while ($row = mysql_fetch_assoc($sql_result)) {

    }

    $sql = "SELECT * FROM reviewsandtips WHERE member_id > 0". $companyname . $location;
    $sql_result = mysql_query($sql); //run the query
    $total_records = mysql_num_rows($sql_result); //count number of records
    $total_pages = ceil($total_records / $num_rec_per_page);

    echo "<a href='codetest.php?page=1'>".'|<'."</a> "; // Goto 1st page

    for ($i=1; $i<=$total_pages; $i++) {
        echo "<a href='codetest.php?page=".$i."'>".$i."</a> ";
    }
    echo "<a href='codetest.php?page=$total_pages'>".'>|'."</a> "; // Goto last page

} else {
    echo '<tr><td colspan="5">No results found.</td></tr>';
}
