php，POST，textarea总是空的

Question

$query = "SELECT * FROM articles WHERE id_article=\"$editid\""; 
      $edited = $db->query($query)->fetch_object(); 
      echo "<form action=\"\" method=\"post\" id=\"add_article\" >"; 
      echo "ID menu <select name=\"urlmenu\" form=\"add_article\">"; 

      $query = "SELECT id_menuitem,url,name FROM menu_item"; 
      $result =$db->query($query); 
      while ($obj = $result->fetch_object()) { 

       echo "<option value=\"$obj->id_menuitem\">$obj->name</option>"; 
      } 

      echo "</select></br>"; 
      echo "Name <input type=text name=name value='$edited->name'></br>"; 
      echo "Perex <input type=text name=perex value='$edited->perex'></br>"; 
      echo "Keywords <input type=text name=keywords value='$edited->keywords'></br>"; 
      echo "<textarea name=content cols=100 rows=20>$edited->content</textarea><br>"; 
      echo '<input type=submit value=Edit name=editstate>'; 
      echo "<input type=hidden value=$editid name=id>"; 
      echo '</form>'; 

if (isset($_POST["editstate"])) 
     { 
      $b = false; 
      $perex = addslashes($_POST["perex"]); 
      $content = addslashes($_POST["content"]); 
      $name = addslashes($_POST["name"]); 
      $id = addslashes($_POST["id"]); 
      echo var_dump($_POST); 
      $query = "UPDATE articles SET perex=\"$perex\", content=\"$content\", name=\"$name\" WHERE id_article = $id"; 
      $db->query($query); 
     } 

我想通过post方法发送表单数据，除textarea之外的所有东西都可以工作。 vardump总是显示其空

array(7) { ["urlmenu"]=> string(1) "1" ["name"]=> string(4) "Abcd" ["perex"]=> string(4) "Dfeg" ["keywords"]=> string(4) "Hjkl" ["editstate"]=> string(4) 
"Edit" ["id"]=> string(1) "5" **["content"]=> string(0)** "" } 

我也试图"form"属性添加到textarea的，但结果总是相同

好吧，这是一个愚蠢的错误，我有两种形式具有相同ID。
