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 brand , ram 和 price ,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);
}
});
})
});
