我有一页来编辑数据。在这种情况下，我将显示该页面以编辑法语数据。问题是，当我以法语粘贴文本并单击以进行编辑和更新时，它假定为mysql_error。这只是发生在法语和英语之间，我可以用葡萄牙语来做到这一点。我只使用这种树语言。
我已经尝试了一些方法，但是没有任何反应...
评论的是我尝试过的。

最佳答案
以此替换您的代码。希望能帮助到你。谢谢。使用mysql_real_escape_string来转义特殊字符，并在查询php变量时删除{}。
if ($_POST)
{
$id = $_POST['id'];
$title_fr = mysql_real_escape_string($_POST['title_fr']);
$subtitle_fr = mysql_real_escape_string($_POST['subtitle_fr']);
$text_fr = mysql_real_escape_string($_POST['text_fr']);
$q = mysql_query ("UPDATE tb_biografia SET title_fr='$title_fr', subtitle_fr='$subtitle_fr', text_fr='$text_fr' WHERE id='$id}'") or die ("Ocorreu um erro, tente de novo! " .mysql_error());
if($q){
echo "<script>alert ('Editado com sucesso'); window.location='admin_biografia.php'</script>";
}
}
