PHP数组没有返回第一次加载 [英] php array not returning on first load

问题描述

我试图调试加载用户的个人资料，可以在其中再编辑形式的Facebook的脚本。

现在的问题是，该脚本不返回 $ USER_PROFILE 数组当您第一次加载页面。但是，页的后续刷新返回数组细

我如何能得到这个数组在页面第一次加载恢复，因此得到了脚本的其余部分运行？它是一个 AJAX 解决方案，或 JSON ？如果是的话我将如何去呢？

在此先感谢。

 ＆LT; PHP
  $ is_fb = FALSE;
  $ is_linkedin = FALSE;
  $ reg_method = $ _GET ['conn_social'];

  如果（使用isset（$ _ GET ['in_uid']））{
    $ cur_in_uid = $ _GET ['in_uid'];
  }

  如果（$ reg_method ==脸谱）{
    $ is_fb = TRUE;
  }
  否则，如果（$ reg_method ==LinkedIn）{
    $ is_linkedin = TRUE;
  }

  如果（$ is_fb）{
    全球$运行fbconfig;
    $ = Facebook的新的Facebook（阵列（'的appid =＆GT; $运行fbconfig ['的appid']，
                                    秘密=＆GT; $运行fbconfig ['秘密']，
                                    '饼干'=＆GT;真正 ））;

    $ USER = $ facebook-＆GT;的getUser（）;

    如果（$用户）{
      尝试 {
        //继续知道你有一个登录谁的身份验证的用户。
        $ USER_PROFILE = $ facebook-＆GT; API（/我）;

        //下面的线仅用于调试 - 这将打印ON SCREEN仅刷新
        的print_r（$ USER_PROFILE）;
      }赶上（FacebookApiException $ E）{
        error_log中（$ E）;
        $ USER = NULL;
      }
    }

    $ is_fb_uid_exist = hl_check_fb_uid_exist（$ USER_PROFILE ['身份证']）;

    如果（$ is_fb_uid_exist）{
      $ is_fb = FALSE;
    }

    尝试{
      $ FQL =选择的名字，名字，姓氏，birthday_date，性别，PROFILE_URL，hometown_location，current_location，工作，活动，兴趣，音乐，电视，电影，书籍，报价，about_me，网站，教育，体育，inspirational_people，语言文字，pic_square从用户其中uid =。 $用户;

      $参数=阵列（'法'=＆GT;fql.query，
                      '查询'=＆GT; $ FQL，
                      '回调'=＆GT; ''）;

      $ fqlResult = $ facebook-＆GT; API（$参数）;
    }

 }
？＆GT;
 

解决方案

在第一行也许问题。

  $ is_fb = FALSE;
 

当页面重定向这是该评估是假的呢？

如果是的话，这是没有执行。

 如果（$ is_fb）{
     //你的code
     //你的code
    }
 

I'm trying to debug a facebook script that loads a users profile into a form which you can then edit.

The problem is that the script does not return the $user_profile array when you first load the page. However, subsequent refreshes of the page return the array fine.

How can I get this array to return on the first load of the page and therefore get the rest of the script to run? Is it an AJAX solution, or JSON? if so how would i go about it?

Thanks in Advance.

<?php
  $is_fb = false;
  $is_linkedin = false;
  $reg_method = $_GET['conn_social'];

  if (isset($_GET['in_uid'])){
    $cur_in_uid = $_GET['in_uid'];
  }

  if ($reg_method == "facebook"){
    $is_fb = true;
  }
  else if ($reg_method == "linkedin"){
    $is_linkedin = true;
  }

  if($is_fb) {
    global $fbconfig;
    $facebook = new Facebook(array( 'appId'  => $fbconfig['appid'],
                                    'secret' => $fbconfig['secret'],
                                    'cookie' => true ));

    $user = $facebook->getUser();

    if ($user) {
      try {
        // Proceed knowing you have a logged in user who's authenticated.
        $user_profile = $facebook->api('/me');

        //the below line is for debugging only - THIS PRINTS ON SCREEN REFRESH ONLY
        print_r($user_profile); 
      } catch (FacebookApiException $e) {
        error_log($e);
        $user = null;
      }
    }

    $is_fb_uid_exist = hl_check_fb_uid_exist($user_profile['id']);

    if($is_fb_uid_exist){
      $is_fb = false;
    }

    try{
      $fql = "select name, first_name, last_name, birthday_date, sex, profile_url, hometown_location, current_location, work, activities, interests, music, tv, movies, books, quotes, about_me, website, education, sports, inspirational_people, languages, pic_square from user where uid=" . $user;

      $param = array( 'method'    => 'fql.query',
                      'query'     => $fql,
                      'callback'  => '' );

      $fqlResult = $facebook->api($param);
    }

 }
?>

解决方案

Maybe problem on the first line..

    $is_fb=false;

when the page is redirecting this is this evaluating as false?

If yes then this is not executing.

   if($is_fb) {
     //Your Code
     //Your Code   
    }
