产品的多个复选框选择(过滤器)

Question

我正在尝试做的是为产品制作过滤器,我正在从数据库中检索产品,包括图像和一些信息,我想要一些过滤器,如:PRODUCT和BRAND

我有这个代码,但当我选择两个过滤器,如品牌1 +产品2,向我展示品牌1的所有产品和所有产品编号2 ..我希望它结合...

这是我的代码:

HTML + PHP

<div id="row" class="row">

<?php

if(!empty($_GET["category"])){
  include('open_conexion.php');
  $sql = "SELECT * FROM products WHERE category='".$_GET["category"]."'";

  $result = mysql_query($sql);

  while ($row = mysql_fetch_array($result)) {

  ?>

  <div class="col-lg-4"  data-category="<?php echo $row['product'];?>" brand="<?php echo $row['brand'];?>" >
      <img  class="img-circle" src='images/<?php echo $row['imag']; ?>'  width="180px;" height="180px;"alt="">
      <h4><?php echo $row['product']." ". $row['brand']; ?></h4>
      <p><?php echo $row['description'];?> </p>
      <p><a class="btn btn-default" href='detalles.php?id=<?php echo $row['id_product']?>'>View Details &raquo;</a></p>

</div><!-- /.col-lg-4 -->



  <?php } } ?>


  </div><!-- /.row -->

和jQuery:

 <script>
$('input[type="checkbox"]').click(function() {
if ($('input[type="checkbox"]:checked').length > 0) {
    $('.row >div').hide();


    $('input[type="checkbox"]:checked').each(function() {
        $('.row >div[data-category=' + this.value + ']').show();
        $('.row >div[brand=' + this.value + ']' ).show();

    });
} else {
    $('.row >div').show();


}
});

谢谢

我假设您正在尝试使用jquery或javascript过滤产品客户端，而不是使用服务器端进行查询。

保留您的复选框和产品列表，如下所示：

<div><input name="product1" id="product1" data-id="1" class="products" type="checkbox" />Product 1</div>
<div><input name="product2" id="product2" data-id="2" class="products" type="checkbox" />Product 2</div>
<div><input name="product3" id="product3" data-id="3" class="products" type="checkbox" />Product 3</div>
<div><input name="brand1" id="brand1" data-id="1" class="brands" type="checkbox" />Brand 1</div>
<div><input name="brand2" id="brand2" data-id="2" class="brands" type="checkbox" />Brand 2</div>
<div><input name="brand3" id="brand3" data-id="3" class="brands" type="checkbox" />Brand 3</div>
<div class="row">
    <div class="product" brand="1" data-category="1">product 1 brand 1</div>
    <div class="product" brand="1" data-category="1">product 1 brand 1</div>
    <div class="product" brand="2" data-category="1">product 1 brand 2</div>
    <div class="product" brand="2" data-category="1">product 1 brand 2</div>
    <div class="product" brand="3" data-category="1">product 1 brand 3</div>
    <div class="product" brand="3" data-category="1">product 1 brand 3</div>

    <div class="product" brand="1" data-category="2">product 2 brand 1</div>
    <div class="product" brand="1" data-category="2">product 2 brand 1</div>
    <div class="product" brand="2" data-category="2">product 2 brand 2</div>
    <div class="product" brand="2" data-category="2">product 2 brand 2</div>
    <div class="product" brand="3" data-category="2">product 2 brand 3</div>
    <div class="product" brand="3" data-category="2">product 2 brand 3</div>

    <div class="product" brand="1" data-category="3">product 3 brand 1</div>
    <div class="product" brand="1" data-category="3">product 3 brand 1</div>
    <div class="product" brand="2" data-category="3">product 3 brand 2</div>
    <div class="product" brand="2" data-category="3">product 3 brand 2</div>
    <div class="product" brand="3" data-category="3">product 3 brand 3</div>
    <div class="product" brand="3" data-category="3">product 3 brand 3</div>
</div>

Javascript代码应该是这样的，我已经使用jQuery进行了过滤。希望您也尝试使用jQuery。

<script type="text/javascript">
$(function(){
    $('.products, .brands').on('click', function(){
        var checkedProducts = $('.products:checked');
        var checkedBrands = $('.brands:checked');
        if(checkedProducts.length || checkedBrands.length){
            if(checkedBrands.length === 0){
                $('.row > div').hide();
                $.each(checkedProducts, function(){
                    var prdId = $(this).attr('data-id');
                    $('.row > div[data-category="' + prdId + '"]').show();
                });
            } else if(checkedProducts.length === 0) {
                $('.row > div').hide();
                $.each(checkedBrands, function(){
                    var brandId = $(this).attr('data-id');
                    $('.row > div[brand="' + brandId + '"]').show();
                });
            } else {
                $('.row > div').hide();
                $.each(checkedProducts, function(){
                    var prdId = $(this).attr('data-id');
                    $.each(checkedBrands, function(){
                        var brandId = $(this).attr('data-id');
                        $('.row > div[data-category="' + prdId + '"][brand="' + brandId + '"]').show();
                    });
                });
            }
        } else {
            $('.row > div').show();
        }
    });
});
</script>

而已！您已保存。.如果您有任何问题，请通知我。
