sql:$sql="delete from `doing` where id in ('1,2,3,4')"; 数据用逗号隔开。 表单:
<form action="?action=doing" method="post">
<input name="ID_Dele[]" type="checkBox" id="ID_Dele[]" value="1"/>
<input name="ID_Dele[]" type="checkBox" id="ID_Dele[]" value="2"/>
<input name="ID_Dele[]" type="checkBox" id="ID_Dele[]" value="3"/>
<input name="ID_Dele[]" type="checkBox" id="ID_Dele[]" value="4"/>
<input type="submit"/>
</form>
好$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$ID_Dele可不是'1,4'哦,因为$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:$ID_Dele= implode(",",$_POST['ID_Dele']); $sql="delete from `doing` where id in ($ID_Dele)";
