Question

这是我的report.php

<?php

    require("config.inc.php");

    if (!empty($_POST)) {

        $query = "SELECT * FROM user WHERE position = 'user'";

        try {
            $stmt   = $db->prepare($query);
            $result = $stmt->execute();
        }
        catch (PDOException $ex) {

            //die("Failed to run query: " . $ex->getMessage());
            $response["success"] = 0;
            $response["message"] = "Database Error 1. Please Try Again!";
            //die(json_encode($response));
        }

        $row = $stmt->fetchAll();

        //No. of shipment that is requested
        $query = "SELECT p.*,s.* FROM parcel p ,shipmentrequest s 
                    WHERE p.parcelstatus= 'requested'
                    AND p.receiverid = s.receiverid
                    AND MONTH(FROM_UNIXTIME(s.requestTime`)) = 05";

        //Again, we need to update our tokens with the actual data:

        try {
            $stmt   = $db->prepare($query);
            $result = $stmt->execute();
        }
        catch (PDOException $ex) {

            //die("Failed to run query: " . $ex->getMessage());
            $response["success"] = 0;
            $response["message"] = "Database Error 2. Please Try Again!";
            //die(json_encode($response));
        }

        $shipmentrow = $stmt->fetchAll();

        $response["success"] = 1;
        $response["message"] = "Summary Report is displayed";
        //echo json_encode($response);
?> 
        <table border="0px" >
        <tr>
            <td>Number of registered user</td>
            <td><input type="text" name="name" value="<?php echo sizeof($row) ?>" readonly/></td>
        </tr>
        <tr>
            <td>Number of requested shipment</td>
            <td><input type="text" name="name" value="<?php echo sizeof($shipmentrow) ?> "readonly/></td>
        </tr>
        </table>
        <?php
        //for a php webservice you could do a simple redirect and die.
        //header("Location: login.php"); 
        //die("Redirecting to login.php");
    }

    else {
        ?>

我想问为什么我的查询$query = "SELECT p.*,s.* FROM parcel p ,shipmentrequest s WHERE p.parcelstatus= 'requested' AND p.receiverid = s.receiverid AND MONTH(FROM_UNIXTIME(s.requestTime)) = 05";

它没有任何MySQL错误，但它并没有返回我想要的结果。我想要的是，当我从Spinner中选择月份时，它将执行查询并获取根据月份的数据行数。

Answer 1

根据您的查询，它将始终从5月（MONTH() = 05）返回项目。如果您希望它返回不同的月份，则必须使用$_POST['month']作为查询的输入。

$query = "SELECT p.*,s.* FROM parcel p ,shipmentrequest s WHERE p.parcelstatus= 'requested' AND p.receiverid = s.receiverid AND MONTH(FROM_UNIXTIME(s.requestTime)) = :month";

$stmt   = $db->prepare($query);
$stmt->bindValue(':month', $_POST['month']);
$result = $stmt->execute();

如何在php中比较时间戳与Spinner中所选月份的月份
