a.php
<input type="checkbox" name="id[]" value=“1”>
<input type="checkbox" name="id[]" value=“2”>
..............b.phpfor($i=0;$i<count($id);$i++) {
$wc.= "\"".$id."\",";
}
$wc = "(".$id."'0')" ;
$strsql="delete from ***** where id in $wc ";
<input type="checkbox" name="id[]" value=“1”>
<input type="checkbox" name="id[]" value=“2”>
..............b.phpfor($i=0;$i<count($id);$i++) {
$wc.= "\"".$id."\",";
}
$wc = "(".$id."'0')" ;
$strsql="delete from ***** where id in $wc ";
<input type="checkbox" name="id[]" value=“1”>
(b.php):
for ($i=0;$i<count($id);$i++)
{
$tmpvalue=$id[$i];
if ($i==0) $tmpstring.=$tmpvalue;
else $tmpstring.=",".$tmpvalue;
}
$strsql="delete from ***** where id in ($tmpstring);
checkbox的名字用数组形式表示，这是php要求的
2、提交后$_POST中有一个id数组，保存有被选中checkbox的value
可以用连接起来使用
$id = $_POST["id"];
$strsql="delete from ***** where id in (". join(",",$id) .")";
