如何驗證wordpress中的類別和標籤字段？

Question

我正在爲wordpress創建驗證帖子，意味着用戶不應該能夠提交空白字段的帖子。

這裏是jquery驗證標題和內容字段，但我無法驗證標籤和類別字段，用戶不應該能夠提交空白類別和空白標籤。任何人都可以請幫助如何使用jquery驗證wordpress中的類別和標籤字段。 categories and tags

jQuery(document).ready(function() { 
    // publish button validation 
    jQuery('#publish').click(function(){ 
     $title_value = jQuery.trim(jQuery('#title').val()); 
     if($title_value == 0 && $title_value != " "){ 
      alert('please insert title'); 
      jQuery('.spinner').css("visibility", "hidden"); 
      jQuery('#title').focus(); 
      return false; 
     } 

     $content_value = jQuery.trim(jQuery('#content').val()); 
     if($content_value == 0 && $content_value != " "){ 
      alert('Please insert content'); 
      jQuery('.spinner').css("visibility", "hidden"); 
      jQuery('#content').focus(); 
      return false; 
     } 
    });

用JQuery你可以得到類別容器並計算檢查輸入的數量。

$("#myButton").on("click", function() { 
 
    /* CATEGORY */ 
 
    // Get all the checkbox checked in your category container 
 
    var arrayChecked = $("#categorydiv input:checked"); 
 
    alert(arrayChecked.length); 
 
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<div id="categorydiv" class="postbox "> 
 
\t <div class="handlediv" title="Click to toggle">

對於標籤，我需要一個標籤的HTML代碼，看看我們如何能比得上它。

$("#myButton").on("click", function() { 
 
    var tagsArray = $("#tagsdiv-post_tag .tagchecklist > span"); 
 
    alert(tagsArray.length); 
 
}); 
 

 
$(".ntdelbutton").on("click", function() { 
 
    $(this).closest("span").remove(); 
 
});

Answer 2

你可以做到這一點通過通過ACF指定標籤和分類，

從後端創建新的自定義字段，

選擇字段類型 - >分類，

帖子類型 - > post，

Taxonomy - > category，

允許空？ - >不，

對post_tag做同樣的處理。
