Question

我知道这可能是一个愚蠢的问题。我有一个用PHP构建的网站，我有一个部分，我想从Wordpress中提取3个响应式帖子。

我尝试过使用API和JSON卷发而没有运气，主要是因为我对这些事情缺乏了解。不知道是否可以更容易地进入PHPMyAdmin然后我可以编码从中提取信息并使其响应？

Answer 1

如果我这样做，我会装配我的WordPress网站发布您尝试呈现的文章的RSS源，并使用一些JavaScript在您自定义的PHP网站上显示该源。

可以使用WordPress插件和JavaScript组件来完成所有这些工作。

Answer 2

所以这是我修改过的php

<section id="blog">
<div class="container-fluid">
    <div class="row">
<div id="featured_posts">

这是我的css

    padding-top: 100px;
    padding-bottom: 100px;

}

#featured_posts {
    background-color: pink;
    max-width: 1200px;
    margin: 0px auto 0px auto;
    padding: 5px;
}

#featured_posts ul {
    display: inline-block;
    margin: 0px auto 0px auto;
    text-align: center;
    padding: 0px;
}

#featured_posts li {
    list-style-type: none;
    text-align: left;
    padding: 30px;
    float: left;
    font-family: pathwaygothic;
    font-size: 1em;
    background-color: purple;
    max-width: 1200px;
    margin-left: 25px;
}

.feed-lists {
  background-color: aqua;
  width: 100%;

}

.feed-title a {
    color: red;
}

.feed-date {
    color: aqua;
}

.feed-description {
    width: 300px;
}

.feed-lists li {
    background-color: green;
}

你可以使用phpmyadmin将wordpress帖子放到外部网站吗？
