Question

我有一个代码，其中我有两个类别的复选框，一个品牌和其他折扣百分比。基于这些复选框，div正在过滤。div的过滤发生好，但有一个小问题。下面是firstphp页面

<html>
<head>
<title>Insert title here</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<style type="text/css">
#image{

height:250px;
border:1px solid black;
}
</style>
</head>
<body>

<script type="text/javascript">
    function get_check_value() {
        var c_value = [];

        $('input[name="brand"]:checked').each(function () {
            c_value.push(this.value);
        });
        return c_value.join(',');

    }
    function get_disc_value(){
    var d_value=[];
        $('input[name="discount"]:checked').each(function () {
            d_value.push(this.value);
        });
        return d_value.join(',');
        }

    $(document).ready(function(){
   checkboxValidate = function (e) {
   if(e)e.preventDefault();
    alert("hi");
        //var os = $('#originState').val();
       //var c = $('#commodity').val();
        //var ds = $('#destState').val();
        var ser = get_check_value();
        var disc=get_disc_value();
        //var queryString = "os=" + os;
        var data = "?ser=" + ser;
        var queryString = "&ser=" + ser;
       // alert(ser);
       $.ajax({
       //alert("ajax");
        type: "POST",
        url: "sortingajax.php",
        data: {ser:ser,disc:disc},
        dataType :  'html',
        success: function (b) {
           // alert(a+' ok. '+b)
            $('#results').html(b);
            console.log(b);
        }
    });

    } 
    $( "[type=checkbox]" ).change(checkboxValidate);

    checkboxValidate();
});
</script>

    <input type="checkbox" name="brand" value="Sunbaby" id="check" />Sunbaby

Asortingajax.php-我在哪里检查数据库

<?php

include('connection.php');

    $brandarray[] = '`BRAND` LIKE "%'.$queryword.'%"';

}
foreach( $query2 as $discword ){
    $discarray[] = '`DPERCENT` < '.$discword.'';

}
if(!empty($query) && !empty($query2))

echo "both loops";
$countsql2='SELECT * FROM xml WHERE  ('.implode ('OR',$brandarray).') AND ('.implode ('OR',$discarray).') ';

}
?>


<?php
foreach($countArray as $array)
{
?>

<div>
<a href="index23.php?name=<?php $array['IMAGEURL']?>"><img src="<?php echo $array['IMAGEURL']?>"/></a></div>

<?php $i++; } ?>

我是第一个php页面。当我一次检查一个品牌复选框和一个折扣复选框时，意味着检查品牌和折扣中的一个是正确过滤的。但是当我检查两个复选框以外的折扣复选框和品牌的一个，我没有正确过滤div，而div应该被过滤。

帮助我们，我在上面的代码中做错了...

Answer 1

你是否回应了查询，看看你得到了什么？在我看来，只要没有真正的内爆和胶水，它就能正常工作。使用过（'OR'）。我认为您需要将胶水部分更改为' OR '（注意它周围的空间）。

在检查两个复选框时没有进入正确的循环
