WordPress 页面模板中的 PHP 代码不执行 [英] PHP code in WordPress page template doesn't execute

问题描述

谁能告诉我为什么 wordpress '页面模板' 中的这段代码不执行?

Can anyone tell me why this code in a wordpress 'page template' doesn't execute?

'Echo' 似乎可以工作，但所有 'include' 和 'print_r()' 以及其他函数都不起作用.这个确切的代码适用于我的家庭服务器，但不适用于 wordpress 托管网站:

'Echo' seem to work but all 'include' and 'print_r()' and other functions don't. This exact code works on my home server but not on wordpress hosted site:

<?php

/**
 * Template Name: fbshares
 *
 * A custom page template for displaying all posts.
 *
 * The "Template Name:" bit above allows this to be selectable
 * from a dropdown menu on the edit page screen.
 *
 * @package WordPress
 * @subpackage Twenty_Ten
 * @since Twenty Ten 1.0
 */

get_header(); ?>

<div id="container">
<div id="content" role="main" class="fullpagejoel">

 <?php 
    echo "x";
    $url = "http://www.google.com";

    $social = array(
        'twitter' => 'http://cdn.api.twitter.com/1/urls/count.json?url=',
        'facebook' => 'https://graph.facebook.com/',
        'stumbleupon' => 'http://www.stumbleupon.com/services/1.01/badge.getinfo?url='
    );

    $json = file_get_contents($social['twitter'].$url, false);
    $a = json_decode($json, true);
    $r['twitter'] = $a['count'];

    print_r($a);
    echo count($a).' [OK]';

 ?>

推荐答案

我刚刚发现了问题.逐项调试后，问题是WordPress不允许您运行file_get_contents，而必须像这样使用wp_remote_get:

I just found the problem. After debugging every bit item by item, the problem is that WordPress doesn't allow you to run file_get_contents, instead you have to use wp_remote_get like this:

GOOD: $json = wp_remote_get( $social['twitter'].$url );
BAD: $json = file_get_contents($social['twitter'].$url, false);

我只是浪费了一整天的时间，所以我希望它可以帮助其他人.

I just wasted a full day on this so I hope it helps someone else.
