PHP 批量操作删除，同时支持单条删除

PHP  执行部分：

<?phpinclude('checkadmin.php');header('Content-Type: text/html; charset=utf-8');if($_POST['btnSave']){if(empty($_POST['id'])){echo"<script>alert('必须选择一个产品,才可以删除!');history.back(-1);</script>";exit;}else{/*如果要获取全部数值则使用下面代码*/$id= implode(",",$_POST['id']);$str="DELETE FROM `product` where id in ($id)";mysql_query($str);echo "<script>alert('删除成功！');window.location.href='product_list.php';</script>";}}?>

HTML 页面部分：

<form id="form2" name="form2" method="post" action="del_product.php"><label><input type="checkbox" name="id[]" value="1" style="background:none; border:none;" />1</label><label><input type="checkbox" name="id[]" value="2" style="background:none; border:none;" />2</label><label><input type="checkbox" name="id[]" value="3" style="background:none; border:none;" />3</label><label><input type="checkbox" name="id[]" value="4" style="background:none; border:none;" />4</label><label><input type="checkbox" name="id[]" value="5" style="background:none; border:none;" />5</label><div style="padding-left:20px;"><input type="button" value="全选" style="background:url(images/cheall.jpg) no-repeat; width:60px; height:23px; border:none;" onClick="selectBox('all')"/><input type="button" value="反选" style="background:url(images/cheall.jpg) no-repeat; width:60px; height:23px; border:none;" onClick="selectBox('reverse')"/><input type="submit" name="btnSave" style="background:url(images/cheall.jpg) no-repeat; width:60px; height:23px; border:none;" value="删除"/></div></form>

 

JS判断部分：

<script type="text/javascript" language="javascript">  function selectBox(selectType){  var checkboxis = document.getElementsByName("id[]");  if(selectType == "reverse"){  for (var i=0; i<checkboxis.length; i++){  //alert(checkboxis[i].checked);  checkboxis[i].checked = !checkboxis[i].checked;  }  }  else if(selectType == "all")  {  for (var i=0; i<checkboxis.length; i++){  //alert(checkboxis[i].checked);  checkboxis[i].checked = true;  }  }}</script>
