mysql - PHP URL Shortener: Shortener.php returning an error message -

-

so creating url shortener site based off of youtube tutorial (phpacademy) due lack of experience in php , mysql, feel i'm picking quickly, receive error message when submitting url.

parse error: syntax error, unexpected 'update' (t_string) in /home/langers/public_html/r/shorten/classes/shortener.php on line 37

however ,in code, line mentions , t_string 'update' implies unexpected, needed in tutorial.

<?php class shortener {     protected $db;      public function __construct() {         //demo purposes         $this->db = new mysqli('localhost', 'langers_langers', 'password','langers_website');     }      protected function generatecode($num){         return base_convert($num, 10, 36);     }      public function makecode($url){         $url = trim($url);          if(!filter_var($url, filter_validate_url)) {             return '';         }          $url = $this->db->escape_string($url);          //check if url exists         $exists = $this->db->query("select code links url ='{$url}'");          if($exists->num_rows){             return $exists->fetch_object()->code;         } else {          //insert record without code         $insert->$this->db->query("insert links (url, created) values ('{$url}', now());          //generate code based on id         $code = $this->generatecode($this->db->insert_id);          //update record         $this->db->query("update links set code = '{$code}' url = '$url'");          return $code;         }     }      public function geturl($code){      } }  ?>

any ideas on how can fix still updates mysql database?

thanks

the error happens before, when miss closing quotes at

//insert record without code $insert->$this->db->query("insert links (url, created) values ('{$url}', now());

please note you're using $insert if object, isn't. perhaps meant:

$insert = $this->db->query("insert links (url, created) values ('{$url}', now())");

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
