如何添加换行符或回车到facebook图形API的描述

问题描述

这听起来像一个很简单的问题，但是我可以找到没有哪里的答案。

我有一个textarea的帖子。我想使用当前的Facebook php库来执行以下操作...

  $ description = $ _POST ['textarea_description' ]。 
 
 //魔术发生
 
 $ attachment = array（
'access_token'=> $ token，
'message'=>$标题，
'picture'=>$ image_url，
'link'=>$ action_link，
'name'=>$ action_label，
'caption'=>$ caption，
'actions'=> $ action_json，
'description'=>$ description，
）; 
 
 $ facebook-> api（'/'.$ my_uid。'/ feed'，'POST'，$ attachment）; 
  

并让它工作。现在似乎忽略了

 < br> < br /> \\\
 \r \\\
\r \r\\\
 
  

但我是确定我可能已经做了一些事来扭转我的测试..我只需要替换'魔术发生'与某些工作。现在它只是将所有的换行符转换成空格。令人沮丧的是。 Facebook的论坛上的人建议添加所有的东西...但似乎没有为我工作

谢谢

解决方案

我写了简单的功能，在每行行文本后添加& nbsp;

  public static function fbLinkDescriptionNewLines（$ string）{
 $ parts = explode（\\\
，$ string ）; 
 $ row_limit = 60; 
 
 $ message =''; 
 foreach（$ parts as $ part）{
 $ str_len = strlen（$ part）; 
 $ diff =（$ row_limit  -  $ str_len）; 
 
 $ message。= $ part; （$ i = 0; $ i $ = $ diff; $ i ++）
 
 {
 $ message。='& nbsp;'; 
} 
} 
 return $ message; 
} 
  

注意：在字符串中，您必须使用 \ n 为新行。

It sounds like a pretty simple question but I can find the answer no where.

I have a post from a textarea. and I want to use the current facebook php library to do the following...

$description = $_POST['textarea_description'];

//magic happens

$attachment =  array(
'access_token' => $token,
'message' => "$title",
'picture' => "$image_url",
'link' => "$action_link",
'name' => "$action_label",
'caption' => "$caption",
'actions' => $action_json,
'description' => "$description",
 );

$facebook->api('/'.$my_uid.'/feed', 'POST', $attachment);

and have it work. Right now it seems to ignore

<br> <br /> \n \r \n\r \r\n

but I am sure I might have done something to screw up my testing.. I just need to replace 'magic happens' with something that works. Right now it just converts all of the newlines I am throwing at it to spaces.. Pretty frustrating. Someone on the facebook forums suggested addslashed() of all things... but that did not seem to work for me

Thanks,-FT

解决方案

I write simple function which add   after every row text.

public static function fbLinkDescriptionNewLines($string){
    $parts = explode("\n", $string);
    $row_limit = 60;

    $message = '';
    foreach($parts as $part){
      $str_len = strlen($part);
      $diff = ($row_limit - $str_len);

      $message .= $part;

      for($i=0; $i <= $diff; $i++){
        $message .= '&nbsp;';
      }
   }
    return $message;
}

NOTE: in your string you must use \n for new lines.
