php - MySQLI 准备语句并显示在表单上使用 PHP Datepicker 输入的日期范围的查询结果

Question

我正在尝试执行 MySQLI 准备好的语句，该语句将查询 MySQL 数据库并根据表单中请求的数据返回结果。我已经能够让这个准备好的语句正常工作，它可以正确地恢复数据。现在我希望能够在查询中添加一个“日期范围”，但我无法让它工作。From我通过创建和To字段在请求表单的顶部添加了一个日期选择器input type="date"。MM/DD/YYYY这会将日期添加到格式的字段中。在数据库中，我正在检查的列是一种date类型，格式为YYYY-MM-DD. 我已经尝试了这个网站的几个不同的建议，以及我在搜索中遇到的其他建议，但得到了错误。我试过使用strtotime和date并得到日期格式错误和致命错误的错误can't construct DatePeriod()。我正在使用 PHP v5.5，所以我读到你可以DateTime::createFromFormat一起使用$string->format，然后使用DatePeriod，这会起作用，但我得到另一个致命错误Call to member function format() on a non-object。请帮忙。

这是“搜索表单”的代码

<form action="../includes/test.inc.php" method="get">
            <table border="0" cellspacing="1">
            <tr>
            Dates:<br>
            From:&nbsp;<input type="date" id="from" name="from"> 

&nbsp;&nbsp;&nbsp;

            To:&nbsp;<input type="date" id="to" name="to"> 

            </br></br>

            Result: <input type="text" name="result" id="result" /><br>
            Employee: <input type="text" name="employee" id="employee" /><br>
            Project: <input type="text" name="project" id="project" /><br>
            Source: <input type="text" name="source" id="source" /><br>
            Appointment Date: <input type="text" name="appt_date" id="appt_date" /><br>
            Branch: <input type="text" name="branch" id="branch" /><br>
            First Name: <input type="text" name="fname" id="fname" /><br>
            Last Name: <input type="text" name="lname" id="lname" /><br>
            Last Four: <input type="text" name="last_four" id="last_four" /><br>
            Phone: <input type="text" name="phone" id="phone" /><br>
            City: <input type="text" name="city" id="city" /><br>
            State: <input type="text" name="state" id="state" /><br>
            Zip: <input type="text" name="zip" id="zip" /><br>


            <input type="submit" value="submit" />
            </tr>
            </table> 
            </form>

这是“表单处理操作”的代码

<?php
include_once 'db_connect.php';
include_once 'psl-config.php';

session_start();

$error_msg = "";

if (isset($_GET['from']))
$date = $_GET['from'];

$fname = $_GET['fname'];
if (isset($_GET['lname']))
$lname = $_GET['lname'];
if (isset($_GET['last_four']))
$last_four = $_GET['last_four'];
if (isset($_GET['phone']))
$phone = $_GET['phone'];
if (isset($_GET['city']))
$city = $_GET['city'];
if (isset($_GET['state']))
$state = $_GET['state'];
if (isset($_GET['zip']))
$zip = $_GET['zip'];

$query = $mysqli->prepare("SELECT set_date, result, employee, project, source, appt_date, branch, fname, lname, last_four, phone, city, state, zip, monthly_net, job_time FROM appointments WHERE set_date LIKE CONCAT('%', ?, '%') AND result LIKE CONCAT('%', ?, '%') AND employee LIKE CONCAT('%', ?, '%') AND project LIKE CONCAT('%', ?, '%') AND source LIKE CONCAT('%', ?, '%') AND appt_date LIKE CONCAT('%', ?, '%') AND branch LIKE CONCAT('%', ?, '%') AND fname LIKE CONCAT('%', ?, '%') AND lname LIKE CONCAT('%', ?, '%') AND last_four LIKE CONCAT('%', ?, '%') AND phone LIKE CONCAT('%', ?, '%') AND city LIKE CONCAT('%', ?, '%') AND state LIKE CONCAT('%', ?, '%') AND zip LIKE CONCAT('%', ?, '%') ORDER BY employee");
if (isset($_GET['from'])) {
    $date = DateTime::createFromFormat('m/d/Y', $_GET['from']);
    $date2 = DateTime::createFromFormat('m/d/Y', $_GET['to']);

    $from = $date->format('Y-m-d');
    $to = $date2->format('Y-m-d');

    $daterange = new DatePeriod($from, $to);
    foreach($daterange as $dr) {
$query->bind_param('sssssssssssssss', $dr, $_GET['set_date'], $_GET['result'], $_GET['employee'], $_GET['project'], $_GET['source'], $_GET['appt_date'], $_GET['branch'], $_GET['fname'], $_GET['lname'], $_GET['last_four'], $_GET['phone'], $_GET['city'], $_GET['state'], $_GET['zip']);
$query->execute();
    }
}
$query->store_result();
$query->bind_result($set_date, $result, $employee, $project, $source, $appt_date, $branch, $fname, $lname, $last_four, $phone, $city, $state, $zip);
$rows = $query->num_rows;
$results = array();
while($row = $query->fetch()) {
    $results[] = array(
    'rows' => $rows,
    'set_date' => $set_date,
    'result' => $result,
    'employee' => $employee,
    'project' => $project,

    );
}
$_SESSION['results'] = $results;
if($results) {
        header('Location: ../test_page.php');
        }else{
        header('Location: ../test.php?error=1');
    }

$query->free_result();
$mysqli->close();
?>

更新：我已经能够消除我收到的所有错误，但仍然无法使日期范围正常工作。我没有更改“表单页面”上的任何代码，但这里是“处理页面”的更新代码。现在我被发送到“error=1”页面，好像没有结果一样，但我知道有结果，如果我删除日期范围部分，它们会正确返回。

我终于能够弄清楚这一点。似乎我试图做的比它需要的更复杂。这是我用来让查询与表单中输入的日期范围一起工作的代码

include_once 'db_connect.php';
include_once 'psl-config.php';

session_start();

$error_msg = "";

if (isset($_GET['from']))
$from = $_GET['from'];
if (isset($_GET['to']))
$to = $_GET['to'];
if (isset($_GET['set_date']))
$set_date = $_GET['set_date'];
if (isset($_GET['result']))
$result = $_GET['result'];
if (isset($_GET['employee']))
$employee = $_GET['employee'];
if (isset($_GET['project']))
$employee = $_GET['project'];
if (isset($_GET['source']))
$source = $_GET['source'];
if (isset($_GET['appt_date']))
$appt_date = $_GET['appt_date'];
if (isset($_GET['branch']))
$branch = $_GET['branch'];
if (isset($_GET['fname']))
$fname = $_GET['fname'];
if (isset($_GET['lname']))
$lname = $_GET['lname'];
if (isset($_GET['last_four']))
$last_four = $_GET['last_four'];
if (isset($_GET['phone']))
$phone = $_GET['phone'];
if (isset($_GET['city']))
$city = $_GET['city'];
if (isset($_GET['state']))
$state = $_GET['state'];
if (isset($_GET['zip']))
$zip = $_GET['zip'];

$from = date("Y-m-d", strtotime($from));
$to = date("Y-m-d", strtotime($to));

$query = $mysqli->prepare("SELECT set_date, result, employee, project, source, appt_date, branch, fname, lname, last_four, phone, city, state, zip FROM appointments WHERE set_date BETWEEN '".$from."' AND '".$to."' AND set_date LIKE CONCAT('%', ?, '%') AND result LIKE CONCAT('%', ?, '%') AND employee LIKE CONCAT('%', ?, '%') AND project LIKE CONCAT('%', ?, '%') AND source LIKE CONCAT('%', ?, '%') AND appt_date LIKE CONCAT('%', ?, '%') AND branch LIKE CONCAT('%', ?, '%') AND fname LIKE CONCAT('%', ?, '%') AND lname LIKE CONCAT('%', ?, '%') AND last_four LIKE CONCAT('%', ?, '%') AND phone LIKE CONCAT('%', ?, '%') AND city LIKE CONCAT('%', ?, '%') AND state LIKE CONCAT('%', ?, '%') AND zip LIKE CONCAT('%', ?, '%') ORDER BY set_date ASC");
$query->bind_param('ssssssssssssss', $_GET['set_date'], $_GET['result'], $_GET['employee'], $_GET['project'], $_GET['source'], $_GET['appt_date'], $_GET['branch'], $_GET['fname'], $_GET['lname'], $_GET['last_four'], $_GET['phone'], $_GET['city'], $_GET['state'], $_GET['zip']);
$query->execute();
$query->store_result();
$query->bind_result($set_date, $result, $employee, $project, $source, $appt_date, $branch, $fname, $lname, $last_four, $phone, $city, $state, $zip);
$rows = $query->num_rows;
$results = array();
while($row = $query->fetch()) {
    $results[] = array(
    'rows' => $rows,
    'set_date' => $set_date,
    'result' => $result,
    'employee' => $employee,
    'project' => $project,
    'source' => $source,
    'appt_date' => $appt_date,
    'branch' => $branch,
    'fname' => $fname,
    'lname' => $lname,
    'last_four' => $last_four,
    'phone' => $phone,
    'city' => $city,
    'state' => $state,
    'zip' => $zip
    );
}
$_SESSION['results'] = $results;
if($results) {
        header('Location: ../appointments_page.php');
        }else{
        header('Location: ../appointments.php?error=1');
 }
$query->free_result();
$mysqli->close();
?>

只需要我的 SELECT 语句中的and$from = date("Y-m-d", strtotime($from)部分。感谢所有的建议，希望这个答案可以帮助别人$to = date("Y-m-d", strtotime($to)WHERE set_date BETWEEN '".$from."' AND '".$to."'

function new_date($str) {
$str = strtotime($str);
$str = date('d-m-Y',$str);
return $str;
}

用法：new_date('YYYY-MM-DD'); 输出：DD-MM-YYYY

function new_date($str) {
$str = strtotime($str);
$str = date('Y-m-d',$str);
return $str;
}

用法：new_date('DD-MM-YYYY'); 输出：YYYY-MM-DD
