Fatal error: Cannot access empty property in

Question

新来的，如果我的帖子不正确，请原谅我。我遇到了这个问题：

Fatal error: Cannot access empty property in /home/content/c/a/l/calchrome/html/gallery/php/includes/php/libmanager.php on line 1363

我在这里找不到语法错误；通常这样的事情很明显，但我想不通。这不是常见的 $this->$var 类型错误。

   foreach($cfg['social_plugin'] as $plugin=>$value)
    {
        $social_order[$this->$value['order']] = $plugin;
    }

    ksort($social_order);

    for($a=1;$a<sizeof($social_order)+1;$a++)

  **this is the section with the problem** 
    {
        $obj = $cfg['social_plugin'][$social_order[$a]];
        $list.='<li id="'.$obj['order'].'_'.($a+1).'"><label for="'.$obj['link'].'"><img src="includes/images/'.$obj['image'].'" /> '.$obj['display'].'</label><input name="'.$social_order[$a].'_L" type="text" id="'.$social_order[$a].'_L" value="'.$this->$obj['link'].'" class="sg_form_long"/></li>';     
    }**

    $html.='<div class="sg_setting_box" id="sortable1">
    <h3>- Soical Information -
    <br/><span>Dragging each plugin can re-arrange the order shown in front end</span>
    </h3>


    <ul class="sg_social">'.$list.'</ul>

    </div>';

Answer 1

变化：

$this->$obj['link']

至

$obj['link']

$this-> 用于当前 class 属性

Answer 2

您应该更改（如果 obj 在您的 class 中定义为属性）来自

$this->$obj['link']

至

$this->obj['link']

OR（如果obj只定义为局部变量）

到 $obj['link']

正如上面建议的答案
