Question

我在准备查询时遇到问题。当$ artistname有撇号时，我收到错误。

$ keyword可以很好地处理撇号。我做错了什么，我该如何解决？

  $keyword[':keyword'.$x] = "%".$name_single."%";

  $where .= '`name` LIKE :keyword'.$x; 
  if ($name_count!=$x) {
    $where .= ' AND ';
  }

  $sql = "SELECT * FROM `mixtapes` WHERE ".$where." AND name != '$artistname' ORDER BY `id` DESC LIMIT 40";
  $search = $db->prepare($sql);
  $search->execute($keyword);

那么你的准备声明没有准备好boysname。使用prepare语句时，将占位符放在查询中，然后执行传递变量进行查询。将artisname添加到数组中，你应该没问题。

$keyword[':keyword'.$x] = "%".$name_single."%";

$where .= '`name` LIKE :keyword'.$x; 
if ($name_count!=$x) {
  $where .= ' AND ';
}

$keyword[':artistname'] = $artistname;

$sql = "SELECT * FROM `mixtapes` WHERE ".$where." AND name != :artistname ORDER BY `id` DESC LIMIT 40";
$search = $db->prepare($sql);
$search->execute($keyword);

无法在PDO中准备语句。撇号错误。
