alert and redirect in codeigniter php using javascript not working-CodePudding

i have a function my controller, when the user clicks a button, the function runs and should show the alret box and then redirect the user to the same page, so i did the following code:

public function addtowishlist()
{
if($this->session->userdata('id'))
{
$id =$this->uri->segment(3);
$this->product->addtowishlist($id);               
  echo '<script type="text/javascript">alert("' . $pname . '")</script>';
redirect($_SERVER['HTTP_REFERER']);
}

              }

however the issue is the alert is coming fine but the redirect to same page is not happening, only i get a blank page, can anyone please help me with this, thanks in advance

CodePudding user response：

Your redirect will execute before alert since PHP is serverside and Javascript is client side, so what you need is redirect with javascript like this

public function addtowishlist() {
 if($this->session->userdata('id')) {
   $id =$this->uri->segment(3);
   $this->product->addtowishlist($id);               
   echo '<script type="text/javascript">
         alert("' . $pname . '");
         window.location.href = "'.$_SERVER['HTTP_REFERER'].'"; ; 
         </script>';
  }
}
