sqlite3 PDO全文搜索不出来...

  • 772

我 nagovnokodil 在这里，但给出了一个错误：

致命错误：在第 19 行的 /site.org/index.php 中的布尔值上调用成员函数 execute()

这是我的分享：

<?php

    $db = new PDO('sqlite:data.db');
    $termin = $_GET['termin'];
    $stmt = $db->query('SELECT * FROM articles WHERE title LIKE %$termin% OR text LIKE %$termin%');
    $stmt->execute();
    $result = $stmt->fetchAll();

?>

<form action="post">
    <input type="text" name="termin" />
    <input type="submit" name="submit" />
</form>
<?php if (empty($termin)): ?>
    <p>Missing term!</p>
<?php elseif (strlen($termin) < 3): ?>
    <p>The term must be at least 3 characters!</p>
<?php elseif ($result < 1): ?>
    <p><?= $termin ?> not found.</p>
<?php else: ?>
    <?php foreach ($result as $row): ?>
        <p>ID: <?= $row['id'] ?></p>
        <p>Date: <?= $row['date'] ?></p>
        <p>Title: <?= $row['title'] ?></p>
        <p>Text: <?= $row['text'] ?></p>
        <p><a href="?id=<?= $row['id'] ?>">More…</a></p>
        <br />
    <?php endforeach ?>
<?php endif ?>
php

    正确的做法：

    // подготавливаем запрос к выполнению
$stmt = $db->prepare('SELECT * FROM articles WHERE title LIKE ? OR text LIKE ?');
// выполняем
$stmt->execute(['%' . $termin . '%', '%' . $termin . '%']);

  2. 这个选项似乎也有效。

    $termin = $_GET['termin'];
$sql = 'SELECT * FROM articles WHERE title LIKE :termin OR text LIKE :termin';
$stmt = $db->prepare($sql);
$stmt->execute(['termin' => "%$termin%"]);
$result = $stmt->fetchAll();

    此外，使用此代码启动 PDO 很重要

    $options = array(
    PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
    PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
);
$db = new PDO('sqlite:data.db', null, null, $options);

    所以它可以报告请求错误
