我试图制作一个搜索引擎，以便在 2 个日期$dateFrom到 $dateTo 之间搜索。
这是我尝试过的：
索引.php：
<?php
require_once 'Connection.simple.php';
$tutorialTitle = "Using Ajax to search a Record with PHP, MySQL and jQuery (Look and Feel by Bootstrap)";
$conn = dbConnect();
?>
<!DOCTYPE html>
<html lang="en">

<meta charset="UTF-8" />
<title><?php echo $tutorialTitle;?></title>

<body>
<div class="wrapper">
<div class="page-header ">
<div class="panel panel-default">
</div>
</div>
<div class="mainContent">
<form class="form-horizontal" role="form" method="get">
<div class="form-group">
<label class="col-sm-2 control-label" for="minimum date">employee_id</label>
<div class="input-group col-sm-9">
<input id="DateFrom" name="DateFrom" type="date" class="form-control" placeholder="Type the name" />
<input id="DateTo" name="DateTo" type="date" class="form-control" placeholder="Type the name" />
<span class="input-group-btn">
<button type="button" class="btn btn-default btnSearch">
<span class="glyphicon glyphicon-search"> Search</span>
</button>
</span>
</div>
</div>
</form>
<div class="col-sm-2"></div>
<div class="col-sm-8">
<!-- This table is where the data is display. -->
<table id="resultTable" class="table table-striped table-hover">
<tbody></tbody>
</table>
</div>
</div>
</div>
<!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->
<script src="js/jquery-1.10.2.js"></script>
<!-- Include all compiled plugins (below), or include individual files as needed -->
<script src="js/bootstrap.min.js"></script>
<script type="text/javascript">
jQuery(document).ready(function($) {
$('.btnSearch').click(function(){
makeAjaxRequest();
});
$('form').submit(function(e){
e.preventDefault();
makeAjaxRequest();
return false;
});
function makeAjaxRequest() {
$.ajax({
url: 'search.php',
type: 'get',
DateFrom: {DateFrom: $('input#DateFrom').val()},
DateTo: {DateTo: $('input#DateTo').val()},
success: function(response) {
$('table#resultTable tbody').html(response);
}
});
}
});
</script>
</body>
</html>
搜索.php：
<?php
require_once 'Connection.simple.php';
$conn = dbConnect();
$OK = true;
if (isset($_GET['DateFrom']) && isset($_GET['DateTo'])) {
$dateFrom = $_GET['DateFrom'];
$dateTo = $_GET['DateTo'];
$sql = "SELECT * FROM attendance WHERE date >= '". $dateFrom ."' AND date <= '". $dateto ."' ";
}
if(empty($rows)) {
echo "<tr>";
echo "<td colspan='4'>There were not records</td>";
echo "</tr>";
}
else {
foreach ($rows as $row) {
echo "<tr>";
echo "<td>".$row['emp_id']."</td>";
echo "<td>".$row['Date']."</td>";
echo "<td>".$row['day']."</td>";
echo "<td>".$row['time_in']."</td>";
echo "<td>".$row['time_out']."</td>";
echo "<td>".$row['worked']."</td>";
echo "<td>".$row['overtime']."</td>";
echo "<td>".$row['less_hours']."</td>";
echo "<td>".$row['transport_in']."</td>";
echo "<td>".$row['Transport_out']."</td>";
echo "</tr>";
}
}
?>
编辑 1：
$sql = "SELECT * FROM attendance WHERE date >= '". $dateFrom ."' AND date <= '". $dateto ."' ";
// we have to tell the PDO that we are going to send values to the query
$stmt = $conn->prepare($sql);
// Now we execute the query passing an array toe execute();
$results = $stmt->execute(array($dateFrom, $dateTo));
// Extract the values from $result
$rows = $stmt->fetchAll();
$error = $stmt->errorInfo();
我添加了它以使执行查询但仍然不起作用
******<?php
function dbConnect (){
$conn = null;
$host = 'localhost';
$db = 'payroll';
$user = 'root';
$pwd = '';
try {
$conn = new PDO('mysql:host='.$host.';dbname='.$db, $user, $pwd);
//echo 'Connected succesfully.<br>';
}
catch (PDOException $e) {
echo '<p>Cannot connect to database !!</p>';
echo '<p>'.$e.'</p>';
exit;
}
return $conn;
}
?>
这是我的数据库连接代码*******
我的数据库名称是工资单，表是出勤。
- 您需要在 SQL 代码中命名参数。
- 请为列名使用正确的大小写。您拼写了"less_hours"，而在数据库中，此列称为"Less_Hours"。这给出了一个通知："未定义的索引：less_hours"。
- 我将输出代码放在 1-st
if中，否则$rows第一次将始终未定义。
这段代码对我有用：
if (isset($_GET['DateFrom']) && isset($_GET['DateTo'])) {
$dateFrom = $_GET['DateFrom'];
$dateTo = $_GET['DateTo'];
$sql = "SELECT * FROM attendance WHERE
date >= :date_from AND date <= :date_to ";
$stmt = $conn->prepare($sql);
// Now we execute the query passing an array toe execute();
$results = $stmt->execute(
array('date_from' => $dateFrom, 'date_to' => $dateTo));
// Extract the values from $result
$rows = $stmt->fetchAll(PDO::FETCH_ASSOC);
if(empty($rows)) {
echo "<tr>";
echo "<td colspan='4'>There were not records</td>";
echo "</tr>";
}
else {
foreach ($rows as $row) {
echo "<tr>";
echo "<td>".$row['emp_id']."</td>";
echo "<td>".$row['Date']."</td>";
echo "<td>".$row['Day']."</td>";
echo "<td>".$row['Time_In']."</td>";
echo "<td>".$row['Time_Out']."</td>";
echo "<td>".$row['Worked']."</td>";
echo "<td>".$row['Overtime']."</td>";
echo "<td>".$row['Less_Hours']."</td>";
echo "<td>".$row['Transport_In']."</td>";
echo "<td>".$row['Transport_Out']."</td>";
echo "</tr>";
}
}
}
