将输入类型从文本更改为多选下拉菜单-技能分类

Question

我在表单上有一个字段，用于在帖子中添加标签。问题是，任何人都可以免费输入任何东西。这将继续填充“技能”分类法。

该代码是：

<div class="form-group skill-control">
    <label><?php _e('Tags', 'themes');?></label>
    <input type="text" class="form-control text-field skill" id="skill" placeholder="<?php _e("Enter tags", 'themes');?>" name=""  autocomplete="off" spellcheck="false" >
    <ul class="skills-list" id="skills_list"></ul>
</div>

我想要的是，它将具有一个下拉多项选择。下拉列表将使用技能分类中的列表进行填充。

到目前为止，我的代码是：

<div class="input-group">
    <label for="skill"><?php _e('Specialist Skills', 'themes');?></label>
    <?php
        ae_tax_dropdown('skill',
            array('attr' => 'data-chosen-width="100%" data-chosen-disable-search="" multiple data-placeholder="' . __("Choose tags", 'themes') . '"',
                'class' => 'chosen chosen-multi multi-tax-item required',
                'hide_empty' => false,
                'hierarchical' => true,
                'id' => 'skill',
                'show_option_all' => false,
            )
        );
    ?>
</div>

目前，代码正在from上运行，但未在帖子中插入标签！当我检索帖子时，没有标签。

如果我使用前面的代码，它将标签添加到帖子中。

完整代码：

if (isset($_GET['return_url'])) {
    $return = $_GET['return_url'];
} else {
    $return = home_url();
}
$currency_code = ae_currency_code(false);
