在前端发布表单中保存两个下拉列表中的两个类别

时间：2012-07-05 作者：Andrew

那么，交易如下：

我有两个类别下拉列表，第一个用于父类别，第二个用于子类别。它们形成一个链，以便在选择父类别时，第二个下拉列表将填充其子类别。以下是表单本身的代码：

    <script type="text/javascript">
    $(function()
    {
    $(\'#main_cat\').change(function()
    {
        var $mainCat=$(\'#main_cat\').val();

        // call ajax
        $("#sub_cat").empty();
        $.ajax
        (
            {
                url:"<?php bloginfo(\'wpurl\'); ?>/wp-admin/admin-ajax.php",     
                type:\'POST\',
                data:\'action=my_special_ajax_call&main_catid=\' + $mainCat,

                success:function(results)
                {
                    //  alert(results);
                    $("#sub_cat").removeAttr("disabled");       
                    $("#sub_cat").append(results);  
                }
            }
        );                                    
    });
    });
    </script>
    <fieldset class="site-url" class="fieldset-first">
    <?php wp_dropdown_categories(\'show_count=0&selected=-1&hierarchical=1&depth=1&hide_empty=0&exclude=1&show_option_none=Main Categories&name=main_cat&taxonomy=category\');
    ?>
</fieldset>
<fieldset class="site-url" class="fieldset-first">
<select name="sub_cat" id="sub_cat" disabled="disabled"></select>
</fieldset>
下面是函数中的代码。php：

function implement_ajax() {
if(isset($_POST[\'main_catid\']))
    {
    $categories=  get_categories(\'child_of=\'.$_POST[\'main_catid\'].\'&hide_empty=0\'.\'&taxonomy=category\'.\'&show_count=0\');
      foreach ($categories as $cat) {
        $option .= \'<option value="\'.$cat->term_id.\'">\';
        $option .= $cat->cat_name;
        $option .= \' (\'.$cat->category_count.\')\';
        $option .= \'</option>\';
      }
      echo \'<option value="-1" selected="selected">Sub Categories</option>\'.$option;
    die();
    } // end if
}
add_action(\'wp_ajax_my_special_ajax_call\', \'implement_ajax\');
add_action(\'wp_ajax_nopriv_my_special_ajax_call\', \'implement_ajax\');
问题是，在像这样保存值时：

\'post_category\' =>   array($_POST[\'main_cat\']),
我将只为帖子保存父类别。我究竟如何才能同时保存父类别和子类别？请记住，每个下拉列表中只能选择一个类别，不能选择多个类别。

干杯

更新了以下全部帖子过账/保存代码：

要解决此问题，您需要通过多个术语而不是单个术语

因此，不是：

$_POST[\'main_cat\']
使用：

array($_POST[\'main_cat\'],$_POST[\'sub_cat\'])
不过，您不需要保存main\\u cat。指定sub\\u cat应该意味着它也在subcat的父术语中

结束

使用wp_Dropdown_USERS和SELECTED()函数？

我有一个自定义的元框，其中有一个下拉列表，通过WP\\u dropdown\\u users显示所有WP用户。它保存了使用post选择的WP用户，以便所有工作正常。但是，是否有办法使其在返回编辑时在下拉列表中显示选定的用户，而不是列表中的第一个用户？我已经将selected（）函数用于另一个下拉列表，但我已经动态创建了它。我尝试用wp\\u dropdown\\u用户实现selected（），但没有成功，所以我不确定这是否可行？谢谢
