前端代码:
<form method="post" action="" onsubmit="set()"> <div class="layui-form-item"> <input type="checkbox" value="1" name="parents" title="1"> <input type="checkbox" value="2" name="parents" title="2"> <input type="checkbox" value="3" name="parents" title="3"> <input type="hidden" name="parent_cat" id="parent" value=""> </div> <div class="layui-form-item"> <button class="layui-btn" style="width:300px" type="submit">下一步</button> </span> </div> </form> <script> function set() { var parents = check_arr(‘parents‘); $(‘#parent‘).val(parents); } function check_arr($str) { var str=document.getElementsByName($str); var objarray=str.length; var chestr=""; for (i=0;i<objarray;i++) { if(str[i].checked == true) { chestr+=str[i].value+","; } } return chestr; } </script>
后台代码:
$parent_cat = $_POST[‘parent_cat‘]; //删除最后一个逗号(post过来的是"1,2,3,") //处理之后变为("1,2,3") $parent_cat = substr($parent_cat,0,strlen($parent_cat)-1); //然后可以分成数组进行处理 $pros = explode(‘,‘,$parent_cat);
