SMARTY Fatal Error

[louis11]

I have been tinkering with SMARTY the last few days, and so far have had little problems. I am moderately familiar with the setup and have read through several articles found through Google as well as the documentation provided on the SMARTY website. With that said, I am having some problems with my SMARTY setup.

I posted this question in the SMARTY forums (http://www.phpinsider.com/smarty-for...?p=51778#51778), but so far no one has been able to help

The error in question is:

Fatal error: Call to a member function assign() on a non-object in /Users/city.php on line 41

City.php contains:

<?
// include configuration files
require_once('includes/configuration.php');
   
global $smarty;

// get action
$action = strip_tags($_GET['action']);
   
// add new city
if($action == 'add')
{
   $smarty -> assign('sub_title', 'Add City');
   $smarty -> display('pages/city_add.tpl');
}
   
// modify existing city
else if($action == 'modify')
{
   $smarty -> assign('sub_title', 'Modify City');
   $smarty -> display('pages/city_modify.tpl');
}
   
// remove city
else if($action == 'remove')
{
   $smarty -> assign('sub_title', 'Remove City');
   $smarty -> display('pages/city_remove.tpl');
}
   
// show navigation
else
{
   $smarty -> assign('sub_title', 'City Management');
   $smarty -> display('pages/city.tpl');
}
?>

and the configuration file required:

<?
// include all library files
require_once('libs/Smarty.class.php');
   
// setup SMARTY
global $smarty;
$smarty = new smarty;
$smarty -> template_dir = 'templates';
$smarty -> compile_dir  = 'templates_c';
$smarty -> cache_dir    = 'cache';
$smarty -> config_dir   = 'configs';
$smarty -> security = true;
?>

I've tried several variations in setting up the smarty resource, but still no good. I added the global $smarty (as I was told to do in the SMARTY forums) and still nothing . . . I even verified that globals where turned on in my php.ini file.

The configuration file is in the correct directory. I verified this multiple times, and even changed the require_once to some arbitrary file name, which produced an error.

I even went as far as to verify that the SMARTY object was being created by doing a print_r($smarty). With and without globals turned on (or specified in the code) it gave the smarty object correctly. So I know the object is being created, and passed from the configuration file.

This is absolutely driving me nuts, any help would be greatly appreciated!

just as a test, stick

print_r($smarty->get_config_vars());

at the top under global $smarty.

Not an expert here but I have been working with smarty for a few months now. I think it has to do with how you are instantiating the smarty object. I would try changing the config file to this.

// include all library files
require_once('libs/Smarty.class.php');
 
// setup SMARTY
class setup extends Smarty
{
      function setup()
      {
      $this->Smarty();
      $smarty -> template_dir = 'templates';
      $smarty -> compile_dir  = 'templates_c';
      $smarty -> cache_dir    = 'cache';
      $smarty -> config_dir   = 'configs';
      $smarty -> security = true;
      }
} 

now on City.php replace

global $smarty; 

with

$smarty = new setup; 

Let me know if this works for you.

I just did a print_r($smarty); and here is what it produces:

I also tried the method proposed by binarysys and it said that it couldn't find the class 'Setup'. So I thought that maybe it can't find the configuration file. So I placed a:

print 'Works!'; 

at the top of my config file, and sure enough when I access city.php (after removing the smarty calls) it prints out 'Works!'. So I assumed it's accessing the config file correctly.

I left out a an important part there you have to put a require statement right before you instantiate the setup.

require_once('config.php'); // path to config
$smarty = new setup; 

It should work now.

Yea someone else in the SMARTY forums recommened:

<?php
class mysmarty
{
  public static function &instance()
  {
    static $smarty_obj = null;
    if(!isset($smarty_obj))
    {
      // include all library files
      require_once('libs/Smarty.class.php');
      // setup SMARTY
      $smarty_obj = new Smarty();
      $smarty_obj -> template_dir = 'templates';
      $smarty_obj -> compile_dir  = 'templates_c';
      $smarty_obj -> cache_dir    = 'cache';
      $smarty_obj -> config_dir   = 'configs';
      $smarty_obj -> security = true;
    }
    return $smarty_obj;
  }
}
?>

and call by

require_once('includes/configuration.php');
$smarty = mysmarty::instance(); 

And that works, tentatively. Now, three templates are shown (city, account, customer) no matter what page you are on.

Try changing the "else if" statements to "if".
