有撇号时搜索不起作用
[英]Search doesn't work when there's an apostrophe
问题描述
我正在尝试制作一个 OPAC 网站。 一切正常，因为它主要是从数据库中选择并显示它。 我注意到当我尝试搜索的书名有撇号时，它什么也不显示。 如果书名不包含任何撇号，则一切正常。 我正在为我的数据库使用 mysql。

我认为这有一些可疑之处：
echo "<a href='article.php?Book_Title=".$row['Book_Title']."&id=".$row['Book_ID']."&call=".$row['Call_Number']."' class= 'search-ref'><div class=search-box>...
看到您的href值被单引号括起来了吗？ 当您单击该链接时，整个查询字符串将在第一个单引号处被截断，这可能是罪魁祸首。
使用： urlencode() on $row['Book_Title']如果它是唯一的麻烦制造者。
echo "<a href='article.php?Book_Title=" . urlencode($row['Book_Title']) . "&id=" . $row['Book_ID'] . "&call=".$row['Call_Number'] . "' class= 'search-ref'><div class=search-box>...
或者这可能会使您的代码更具吸引力（当然更健壮）：
$data = [
'Book_Title' => $row['Book_Title'],
'id' => $row['Book_ID'],
'call' => $row['Call_Number']
];
echo "<a href='article.php?" . http_build_query($data) . "' class='search-ref'><div class=search-box>...
