我有这个PHP代码来从数据库中获取数据
<?php
require_once ("db.php");
$db = new MyDb();
if (isset($_POST['limit']) && isset($_POST['start'])) {
$start = $_POST["start"];
$limit = $_POST["limit"];
$query =<<<EOF
SELECT * FROM questions ORDER BY quiz_id DESC '$start', '$limit';
EOF;
$result = $db->query($query);
while ($row = $result->fetchArray(SQLITE3_ASSOC)) {
echo 'div class="quesbox">
<div class="questitle">
<h2>'.$row["question"].'</h2>
</div>
<div class="quesanswer">'.$row["answer"].'</div>
<div class="quesdatetime"><img src="images/questime.png" alt="export question">'.$row["date"].'</div>
</div>';
}
}
?>
但是每次运行这段代码我都会遇到这些错误
Warning: SQLite3::query(): Unable to prepare statement: 1, near "'0'": syntax error in C:\xampp\htdocs\xport\searchfetch.php on line 14
Fatal error: Call to a member function fetchArray() on a non-object in C:\xampp\htdocs\xport\searchfetch.php on line 16
我已经尝试了所有可能的方法,通过编辑query
语句来解决问题,但无济于事。请问问题在哪里。任何帮助将不胜感激。
答案 0 :(得分:2)
您忘记了LIMIT
$query =<<<EOF
SELECT * FROM questions ORDER BY quiz_id DESC LIMIT '$start', '$limit';
EOF;
