Question

呃，我有过滤器的问题，我为价格范围创建过滤器，但是我需要将该数据排序为asc或desc？

我怎么能把那个东西搞砸了？

这是我的价格范围代码。

if(isset($_POST['sort'])) {

    $cena_no = mysql_real_escape_string(trim($_POST['fl_cena_no']));
    $cena_lidz = mysql_real_escape_string(trim($_POST['fl_cena_lidz']));    

    if(empty($cena_lidz)){
        $cena_lidz = '99999999999999999999999999999999';
    }

    if(empty($cena_no)){
        $cena_no = '0';
    }

    $_SESSION['sort'] = $_POST;                     
    $per_page = $default;
    $page = isset($_GET['page']) ? (int) $_GET['page'] : 1;
    $rows = mysql_query("SELECT * FROM zirglietas_pardod WHERE cena BETWEEN $cena_no AND $cena_lidz");
    $pages = mysql_num_rows($rows);
    $pages = ceil($pages / $per_page);
    $querystring = "";

    foreach ($_GET as $key => $value) {
        if ($key != "page") $querystring .= "$key=$value&amp;";
    }

    $result = mysqli_query($con,"SELECT * FROM zirglietas_pardod WHERE cena BETWEEN $cena_no AND $cena_lidz LIMIT " . (($page - 1) * $per_page) . ", ".$per_page."");
    echo '<script>window.location.href = "pardod.php?page=1";</script>';
}

会话代码

if(isset($_SESSION['sort'])) {

    $cena_no = $_SESSION['sort']['fl_cena_no'];
    $cena_lidz = $_SESSION['sort']['fl_cena_lidz'];

    if(empty($cena_lidz)){
        $cena_lidz = '99999999999999999999999999999999';
    }

    if(empty($cena_no)){
        $cena_no = '0';
    }

    $per_page = $default;
    $page = isset($_GET['page']) ? (int) $_GET['page'] : 1;
    $rows = mysql_query("SELECT * FROM zirglietas_pardod WHERE cena BETWEEN $cena_no AND $cena_lidz");
    $pages = mysql_num_rows($rows);
    $pages = ceil($pages / $per_page);
    $querystring = "";

    foreach ($_GET as $key => $value) {
        if ($key != "page") $querystring .= "$key=$value&amp;";
    }

    $result = mysqli_query($con,"SELECT * FROM zirglietas_pardod WHERE cena BETWEEN $cena_no AND $cena_lidz LIMIT " . (($page - 1) * $per_page) . ", ".$per_page."");
}

当我发布价格范围后，我需要订购数据asc或desc，我创建了用于排序asc或desc的表单，但我无法更改会话数据。

这用于排序数据，但是当我启动价格范围会话时它不起作用。会话开始，但没有改变。

if(isset($_POST['cena_asc'])) {
    $cena_asc = mysql_real_escape_string($_POST['input_asc']);
    $_SESSION['cena_asc'] = $_POST;
    $result = mysqli_query($con,"SELECT * FROM zirglietas_pardod ORDER BY cena $cena_asc LIMIT " . (($page - 1) * $per_page) . ", ".$per_page."");
    echo '<script>window.location.href = "?page=1";</script>';
}

if(isset($_SESSION['cena_asc'])) {
    $cena_asc = $_SESSION['cena_asc']['input_asc'];
    $result = mysqli_query($con,"SELECT * FROM zirglietas_pardod ORDER BY cena $cena_asc LIMIT " . (($page - 1) * $per_page) . ", ".$per_page."");
}
