有撇号时搜索不起作用

Question

我正在尝试制作一个 OPAC 网站。一切正常，因为它主要只是从数据库中选择并显示它。我注意到当我试图搜索的书名有一个撇号时，它什么也没有显示。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。

Answer 1

我认为这其中有些可疑：

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 值用单引号引起来了吗？当您单击 link 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。

如果它是唯一的麻烦制造者，请在 $row['Book_Title'] 上使用 urlencode()。

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>...
