php一次性删除前台checkbox多选内容的方法
如何一次性删除前台checkbox多选的内容,在本文将为大家介绍下php中时如何实现的,感兴趣的你可不要错过了哈
代码如下:
SQL:$SQL="delete from `doing` where id in ('1,2,3,4')";
数据用逗号隔开。
表单:
代码如下:
<form action="?action=doing" method="post"> <input name="ID_Dele[]" type="checkbox" id="ID_Dele[]" value="1"/> <input name="ID_Dele[]" type="checkbox" id="ID_Dele[]" value="2"/> <input name="ID_Dele[]" type="checkbox" id="ID_Dele[]" value="3"/> <input name="ID_Dele[]" type="checkbox" id="ID_Dele[]" value="4"/> <input type="submit"/> </form>
好$ID_Dele=$_POST['ID_Dele']将会是一个数组,虽然说PHP是弱类型的,但这里可没ASP弱。
ASP可以直接:
SQL="delete from [doing] where id in ('"&ID_Dele&"')"进行删除。但PHP不能把$ID_Dele直接放进去。因为$ID_Dele可不是'1,2,3,4'哦,因为$ID_Dele是一个数组,具有键和值。
好,PHP中也不难,刚好有个函数:implode(),对了。同split()\explode()功能刚好相反的一个函数,后两者是用某字符(比如逗号)分割的,而前者则可以拼接为字符串。
因此:
代码如下:
$ID_Dele= implode(",",$_POST['ID_Dele']); $SQL="delete from `doing` where id in ($ID_Dele)";
