当用户删除从echo "<a href=\"delete.php?sqluid=".$row[sqluid]."\"><img title='Delete Row' alt=\"Delete\" class='del' src='images/delete.png'/></a></form></div>\n";语句完成的条目时，我正在尝试创建一个确认框。尝试使用“onlick”运算符和一些将href重定向到delete语句的javascript。尝试了我在这个网站上找到的6种不同的代码，但我不认为我正确地实现了它。当我检查php日志时，不断得到一个未定义的常量错误

答案 0 :(得分：0)
$ row [sqluid]应该是$ row ['sqluid']，并且在构建输入元素时还有几个更像它。
