问题描述
我想在我的控件中添加选项,例如 key =>;value
对所有可用选项的数组
I want to add options in my control like key => value
pair array of all available options
像这样:
$this->add_control('show_elements', [
'label' => __('Show Elements', 'your-plugin'),
'type' => Controls_Manager::SELECT2,
'options' => [
'title' => __('Title', 'your-plugin'),
'description' => __('Description', 'your-plugin'),
'button' => __('Button', 'your-plugin'),
],
'multiple' => true,
]
);
但是为了代替标题描述和按钮,我想拥有我帖子的所有类别,所以我编写了一个函数 my_cat
But in place of title description and button I want to have all the categories of my post so I write a function my_cat
function my_cat() {
$categories = get_categories();
echo '[';
foreach ($categories as $category) :
echo $category->term_id . '=>' . $category->name . ',';
endforeach;
echo ']';
}
我将它用于选项
$this->add_control('show_elements', [
'label' => __('Show Elements', 'your-plugin'),
'type' => Controls_Manager::SELECT2,
'options' => my_cat(),
'multiple' => true,
]
);
但是我没有得到类别列表的选项,my_cat
函数有什么问题吗?
But I'm not getting option with category list, is there anything wrong with my_cat
function ?
推荐答案
尝试将您的 my_cat()
替换为:
Try by replacing you my_cat()
with this:
function my_cat() {
$categories = get_categories();
$cat_array = [];
foreach ($categories as $category) :
$cat_array[$category->term_id] = $category->name;
endforeach;
return $cat_array;
}
为了正确地做到这一点,我们希望 choices
采用这种形式的关联数组:
To do this correctly, in opinion, we want choices
to take associative array in this form:
$this->add_control('show_elements', [
'label' => __('Show Elements', 'your-plugin'),
'type' => Controls_Manager::SELECT2,
'choices' => my_cat(), //<-- Check this line.
'multiple' => true,
]
);
参考:添加控件
