数据用逗号隔开,表单:
- <form action="" 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>
$ID_Dele=$_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',$ID_Dele是一个数组,具有键和值.
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:
$ID_Dele= implode(",",$_POST['ID_Dele']);
$SQL="delete from `doing` where id in ($ID_Dele)"; |
