协助 PDO (PHP, mySQL) 的 datepicker 和 HTML table filter

Question

我这几天一直在看/阅读教程、编码/重新编码等，但仍然无法让我的功能正常工作。我有一个由使用 PHP 的 mySQL 数据库中的数据填充的 HTML 表组成的网页。我已经添加了一个日期选择器、脚本​​和一个带有用户输入的表单，但是没有成功让 HTML 表根据那些 from 和 to 日期从日期选择器。我的困难在于 PDO 语法：我找不到任何使用 PDO 的教程。有人可以帮忙吗？我已经尝试过 AJAX 和 jquery 数据表，但它们最终破坏了我的表，我仍然无法让日期选择器返回结果。图片如下所示，是我的页面的样子。

<input type="text" placeholder="To Date" id="to_date" name="to_date" style="margin-left:10px"  class="input-control"  />

我在您的查询中没有看到您告诉查询查找介于您的开始日期和结束日期之间的日期。

将此代码放入您的 php 块中：

include 'database.php';
$pdo = Database::connect();
$sql = 'SELECT * FROM general_ledger a
LEFT JOIN balance b ON a.gen_led_id=b.bal_gen_led_id
LEFT JOIN receipts c ON a.gen_led_id=c.rec_gen_led_id
LEFT JOIN ref_gen_led_expense_type d ON 
a.gen_led_expense_type=d.ref_gen_led_expense_typ
LEFT JOIN ref_gen_led_transaction_type e ON 
a.gen_led_transaction_type=e.ref_gen_led_transaction_typ
LEFT JOIN ref_gen_led_income_type f ON 
a.gen_led_income_type=f.ref_gen_led_income_typ
LEFT JOIN member g ON a.gen_led_users_mem_no=g.mem_no
LEFT JOIN balance h ON a.gen_led_id=h.bal_gen_led_id
LEFT JOIN users i ON a.gen_led_add_by=i.user_mem_no

WHERE a.gen_led_trans_date >= :from_date && 
a.gen_led_trans_date <= :to_date';

// This is some code I have to sort the table by column name with a page     refresh -->
if(isset($_GET['sort'])){
if ($_GET['sort'] == 'id')
{
    $sql .= " ORDER BY gen_led_id DESC";
}
elseif ($_GET['sort'] == 'date')
 {
    $sql .= " ORDER BY gen_led_trans_date";
}
elseif ($_GET['sort'] == 'mem_no')
{
    $sql .= " ORDER BY mem_no";
}
}

$stmt = $pdo->prepare($sql);

$stmt->bindParam(":from_date", date('Y-m-d 00:00:00', strtotime($_POST['from_date'])));
$stmt->bindParam(":to_date",     date('Y-m-d 23:59:59', strtotime($_POST['to_date'])));

$stmt->execute();

$stmt->setFetchMode(PDO::FETCH_ASSOC);

while ($row = $stmt->fetch()) {

  echo '<tr>';
  echo '<td>'. $row['gen_led_id'] . '</td>';
  echo '<td>'. $row['gen_led_trans_date'] . '</td>';
  echo '<td>'. $row['rec_receipt_no'] . '</td>';
  echo '<td>'. $row['mem_no'] . '</td>';
  echo '<td>'. $row['mem_fname'] . '</td>';
  echo '<td>'. $row['mem_lname'] . '</td>';
  echo '<td>'. $row['gen_led_description'] . '</td>';
  echo '<td>'. $row['ref_gen_led_transaction_desc'] . '</td>';
  echo '<td>'. $row['gen_led_amount'] . '</td>';
  echo '<td>'. $row['ref_gen_led_expense_desc'] . '</td>';
  echo '<td>'. $row['ref_gen_led_income_desc'] . '</td>';
  echo '<td>'. $row['bal_acct_balance'] . '</td>';
  echo '<td>'. $row['gen_led_add_by'] . '</td>';
  echo '<td><a class="btn"     href="admin_user_receipt.php?rec_receipt_no='.$row['rec_receipt_no'].'">View    Receipt</a></td>';
  echo ' ';
  echo '</tr>';

 }

 Database::disconnect();

一些内容供您阅读： PDO 查询和准备好的语句。 php date() 函数及其格式。 php strtotime()函数及使用。

您的日期选择器会在 yy-mm-dd 格式。您需要确保此日期格式与您的数据库时间格式相匹配。这应该会为您指明正确的方向。

您需要知道表格上的日期格式。我猜是 Y-m-d H:i:s。所以我从 yy-mm-dd 转换。这些并没有什么不同。一种是 javascript 表示法，另一种是 PHP 表示法。

Answer 2

我建议您再次检查数据表，这对您的代码来说真的很难。使用数据表，您可以使用 rang date filter 轻松添加它
