$ _Server [php_self]我需要传递多个变量

标签： javascript php html oracle

我将在我的代码中放下一个php，它在oracle数据库中发出请求但是有了firlters。问题是我有一个startrow变量，可以帮助我对结果进行分页。但是我需要将$ data1和$ data2以及$ cod传递给下一页，但我不知道如何。

这是我的完整代码，除了案例的重复部分：

<?php
//Oracle DB user name
$username = 'TW';

// Oracle DB user password
$password = 'TW';

// Oracle DB connection string
$connection_string = 'localhost/xe';

//Connect to an Oracle database
$connection = oci_connect(
    $username,
    $password,
    $connection_string
);

$data1 = NULL;
$data2 = NULL;
$cod = NULL;
$flagData1 = -1;
$flagData2 = -1;
$flagCod = -1;
$data1=$_POST['data1'];
$data2=$_POST['data2'];
$cod=$_POST['cod'];

if (!isset($_GET['startrow']) or !is_numeric($_GET['startrow'])) {
    //we give the value of the starting row to 0 because nothing was found in URL
    $startrow = 0;
    //otherwise we take the value from the URL
} else {
    $startrow = (int)$_GET['startrow'];
}

if ($cod !=NULL) {
    if ((is_numeric($cod) == true)) {
        $stid3 = oci_parse($connection, 'SELECT COUNT(*) as "count" FROM CEREREVIZITE WHERE COD_DETINUT=:cod');

        if (!$stid3) {
            $e = oci_error($connection);
            trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
        }

        oci_bind_by_name($stid3, ':cod', $cod);

        $r3 = oci_execute($stid3);

        if (!$r3) {
            $e = oci_error($stid3);
            trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
        }
        $row3 = oci_fetch_array($stid3, OCI_ASSOC + OCI_RETURN_LOBS);
        $count3 = $row3['count'];
    } else $count3 = 0;

    if ($count3 == 0) {
        $message = "EROARE! Cod invalid! ";
        echo "<script type='text/javascript'>alert('$message'); window.location.href = \"../administrare.html\";</script>";
        exit ();
    } else $flagCod = 1;
} else $flagCod = 0;

if ($data1 == NULL) $flagData1 = 0;
    else $flagData1 = parse_data($data1);

if ($data2 == NULL) $flagData2 = 0;
    else $flagData2 = parse_data($data2);

if ($flagData1 == -1) {
    $message = "EROARE! Data1 invalida ";
    echo "<script type='text/javascript'>alert('$message'); window.location.href = \"../administrare.html\";</script>";
    exit ();
}

    $message = "EROARE! Data2 invalida ";
    echo "<script type='text/javascript'>alert('$message'); window.location.href = \"../administrare.html\";</script>";
    exit ();
}

if ($flagCod == 0 AND $flagData1 == 0 AND $flagData2 ==0){
    $message = "DATE INEXISTENTE SAU GRESITE! ";
    echo "<script type='text/javascript'>alert('$message'); window.location.href = \"../administrare.html\";</script>";
    exit ();
}

    }
    oci_bind_by_name($stid2, ':data2', $data2);

    if (!$r2) {
        $e = oci_error($stid2);
        trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
    }
    $row2 = oci_fetch_array($stid2);
    $count = $row2[0];
    if ($count == 0) {

<?php

        if ((substr($data, 0, 2) == "02" AND substr($data, 3, 2) > "28") OR ((substr($data, 0, 2) == "01" OR substr($data, 0, 2) == "03" OR substr($data, 0, 2) == "05" OR substr($data, 0, 2) == "07" OR substr($data, 0, 2) == "08" OR substr($data, 0, 2) == "10" OR substr($data, 0, 2) == "12") AND substr($data, 3, 2) > "31") OR (((substr($data, 0, 2) == "04" OR substr($data, 0, 2) == "06" OR substr($data, 0, 2) == "09" OR substr($data, 0, 2) == "11")) AND substr($data, 3, 2) > "30")) $flag = -1;

        if (substr($data, 6, 4) > "2017" OR substr($data, 6, 4) < "1900") $flag = -1;

        if (strlen($data)>10) $flag=-1;
    }

    return $flag;
}
?>

这是我遇到问题的部分：

if ($prev >= 0) {
            echo '<a class="da" href="' . $_SERVER['PHP_SELF'] . '?startrow=' . $prev . '">Previous</a>';
        }
        if ($count >= 30) {
            echo '<a class="da2" href="' . $_SERVER['PHP_SELF'] . '?startrow=' . ($startrow + 30) . '">Next</a>';
        }

您可以通过用&分隔多个参数来传递它们。您还可以使用http_build_query()从关联数组构造URL查询字符串。

$params = array('data1' => $data1, 'data2' => $data2, 'cod' => $cod);
$params['startrow'] = $prev >= 0 ? $prev : ($startrow + 30);
$query = http_build_query($params);
echo '<a class="da" href="' . $_SERVER['PHP_SELF'] . '?' . $query . '">Previous</a>';
