获取带有多选复选框的Ajax帖子过滤器的帖子

提问于

我试图用一个使用 muti-selection checkboxes 的表单来实现 an ajax post filter . 我缩短了表格,只有3组,每组4个复选框(而不是11组) .

这里我的过滤器有3个 groups (主密钥),它们是 brandramprice ,每个组有4个不同的键/值(复选框) . 可以检查组中的每个复选框(多选)

这是该项目的实时链接,如果您使用浏览器控制台工具进行检查,您将看到数据由jQuery正确发送并由我的php函数接收 .

This is working:
带有所有复选框的 HTML 文件与我的ajax jQuery脚本一起工作正常,并且 sends correctly 我的php函数的键/值数组 . 我已正确注册我的jQuery脚本并使用了

The array of data received (对于2个选中的复选框,例如同一组):

$choices = array( 'brand1' => 'Nokia', 'brand3' => 'Sony' );**`wp_localize_script()`**…

什么还没有工作: - 为WP_query()准备数据 - 查询自己$ args数组

如何管理call_post()函数,之后它从JS获取值并使用循环显示帖子?? **

function.php中的PHP代码:

add_action('wp_ajax_call_post', 'call_post');
add_action('wp_ajax_nopriv_call_post', 'call_post');
function call_post(){

$choices = $_POST['choices'];
print_r($_POST['choices']);
foreach($choices as $name => $choice)
    $fam = explode('-', $name);
    $family = $fam[0];       
}

$args = array(
    'post_type' => 'post',
        array(
            'key' => 'brand',
            'value' => $brand,
        ) ,
         array(
            'key' => 'ram',
            'value' => $ram,
        ) ,
         array(
            'key' => 'price',
            'value' => $price,
    ) ,
);

$query = new WP_Query($args);
    if( $query->have_posts() ) :
        while( $query->have_posts() ): $query->the_post();
          echo file_get_contents(locate_template("content.php"));
        endwhile;
        wp_reset_query();
    else :
        wp_send_json($query->posts);
    endif;
 die();
}

脚本

jQuery(document).ready(function($){
    $('#phones-filter .br').click(function(){

        var choices = {}; // declaring an empty array
        var choice = $(this).attr('name');
        $('.contents').remove();
        $('.filter-output').empty();

        // scanning each checkbox for checked state data
        $('div > li > .br').each(function(index, obj) {
            if($(this).prop('checked')){
                var name = $(this).attr('name'), val = $(this).val();
                choices[name] = val;
            }
        });

        $.ajax({
            url: ajaxobject.ajaxurl,
            type :'POST',
            data : {
                'action' : 'call_post',
                'choices' : choices,
            },
            success: function (result) {
                $(choice).appendTo('.filter-output');
                console.log(result);
                console.log(choices);
            },
            error: function(err){
                console.log(err);
                console.log(choices);
            }
        });
    })
});
