its not my Method

It seems to e an error with my in_array command.

Code :-

$a= strncmp(".$method.", '_', 1);
echo "STRCOMPARE1 - $a
\n";
$a=class_exists($class);
echo "STRCOMPARE2 - $a
\n";
$a=(in_array(strtolower($method), array_map('strtolower', get_class_methods('Controller'))));
echo "STRCOMPARE3 - $a
\n";

Output :-

STRCOMPARE1 - -1
STRCOMPARE2 - 1
STRCOMPARE3 -

So, as in_array isn’t producing any results - it activates the 404 page ?

is this right / Correct ?

Can someone advise how to fix it, & what that line actually means (in emglish)...

Ps, using my friends login, incorrectly….

in_array returns a boolean, which doesn’t display with echo.

try

echo "STRCOMPARE3 - ",($a ? "TRUE" : "FALSE"),"
\n";

$a= strncmp(”.$method.”, ‘_’, 1);<br /> echo “STRCOMPARE1 - $a<br /> \n”;<br /> $a=class_exists($class);<br /> echo “STRCOMPARE2 - $a<br /> \n”;<br /> $a=(in_array(strtolower($method), array_map(‘strtolower’, get_class_methods(‘Controller’))));<br /> echo “STRCOMPARE3 - $a<br /> \n”;</p> <p>echo “STRCOMPARE32 - “,($a ? “TRUE” : “FALSE”),”<br /> \n”;

STRCOMPARE32 = FALSE

EDIT :- so, something in the ‘in_array’ command - Produces ‘false’ - which results in the 404 error.

Are there any steps I can take - How do I check what should be / Is in this array… - it seems to combine 3 functions (None of which I am familiar with)...

Show us that home controller. It’s very unlikely that this is a CI issue…

Ive removed comment lines starting with //

<?php

class Home extends Controller {

function Home()
{
parent::Controller();
echo "VIEWING ROOT FILE
\n";

}

  function about()
  {

$data['head_text'] = trim("Title of page");

$this->smarty_parser->parse('about.tpl',$data);
}

  function safety()
  {

$data['head_text'] = trim("Title of page");

$this->smarty_parser->parse('safety.tpl',$data);
}

  function examples()
  {

/// LOGS DEBUG
//$this->output->enable_profiler(TRUE);
$data['head_text'] = trim("Title of page");

$this->smarty_parser->parse('examples.tpl',$data);
}

  function goto()
  {
if ($where = $this->input->post('newpage'))
redirect($where);
else
echo "GO WHERE $where
\n";
}

  function index()
  {

/// LOGS DEBUG
$this->output->enable_profiler(TRUE);
// error_reporting(E_ALL);
// $data["rotate_head_message"]=header_message();
$data['show_map'] = "no";
$data['head_text'] = trim("Title of page");
#print_r($data);
# $pieces_title = explode(" ", $data['head_title');

// Title random number
$r=rand(1,100);
$data['title_random'] = $r;

$this->load->model('Header_rotate');
// If using multiple templates to display a page
// then each except the last one should be "displayed"
// to send it to the screen.
$this->smarty_parser->parse("mainpage.tpl", $data);
}

}
/* End of file root.php */
/* Location: ./system/application/controllers/welcome.php */

 

(Ive renamed the page from welcome/root/home etc - But all file-names are correct.. )

EDIT:-  /controllers/home.php (correct / new filename)

Do you have error reporting enabled, and display errors set to ‘on’ in php.ini?

If so, you would have seen errors in your log files.

The issue here is that the class doesn’t load, because ‘goto’ is a reserved word, that causes a parse error.

I’m still fairly new to CI, but not programming… where is your $this->smarty_parser loaded? And I’m not sure what you mean about there being nothing about methods… the underscore is for “private” methods… meaning that they can’t be accessed via the URL. Example: currently, with the controller above, the following url will work: index.php/home/about .... but if you were to change it to function _about .... then index.php/home/_about would not work. How ever, from within the controller $this->_about would work.

Good call on that Wan - I didn’t even see that.

what errors in logs ?

php.ini

error_reporting = E_ALL & E_NOTICE
display_errors = On
error_log = ‘c:\phpnew\logs\error.log’

(I also had error_log = /phpnew/logs/error.log )

- No logs & no php errors - Directory does exist…

PS - its the “Codeigniter” 404 file being displayed - Not a incorrect web-page (browser 404 page)... - so PHP is being run - & if I put phpinfo(); I do get results…

The issue here is that the class doesn’t load, because ‘goto’ is a reserved word, that causes a parse error.

I’ll remember that - for future, but thats still not the issue…

I saved my home.php script into a new name, & adjusted the controllers/home.php script as so :- (taking out a lot)..

Took out a LOT of functions - Bare basics…

<?php

class Home extends Controller {

function Home()
{
parent::Controller();
echo "VIEWING ROOT FILE
\n";

}

  function index()
  {

/// LOGS DEBUG
$this->output->enable_profiler(TRUE);
$data['show_map'] = "no";
$data['head_text'] = trim("Title of page");

$r=rand(1,100);
$data['title_random'] = $r;

$this->load->model('Header_rotate');
$this->smarty_parser->parse("mainpage.tpl", $data);
}

}
/* End of file root.php */
/* Location: ./system/application/controllers/welcome.php */

 

Still no go…

I’ll check the $this->smarty_parser thing - However - Even if the templates don’t get parsed as “smarty” - They’ll be loaded / parsed as “something” (even if incorrect HTML code is shown…)

I’ve copied your home controller into a fresh CI 1.7.2 install here, and get the parse error.
You get the CI 404 error because ‘get_class_methods(‘Controller’)’ doesn’t return data, since the class didn’t load.

If I change ‘goto’ to ‘x’, the home controller loads without problems.

If I copy the stripped home controller code in as per your post, it loads without problems (I get the “VIEWING ROOT FILE” text, and the can’t find the model error).

Just checking, this controller is in /system/application/controllers/home.php ?

C:\home\sites\SITE-NAME\application\controllers\home.php = Yes

Tomorrow, I may just remove / rename the directories - & re-install Apache / CI from scratch

& may install my own “debug” class (If i’m bothered..) ) - To tell us (me) more information.. - But thats long-term not short-term 😊

Ok.. - COOL tool.

I used the PHP ‘backtrace’ command - (didn’t know of it before) - Though I’ve figured it goes from bottom-up..

Here is the backtrace

I guess I’ll re-install Smarty…

IDENTIFIED ERROR FILE :- C:\usr\local\lib\codeigniter\current\system\libraries\Loader.php

I’m getting close, & I’ve also identified a flaw in the order / process of the Loader.php file..

First of, My output (I added a LOT of log_message lines 😊 )

In this function - function _ci_load_class of Loader.php - I’ll quote a bit..

    // We’ll test for both lowercase and capitalized versions of the file name
      foreach (array(ucfirst($class), strtolower($class)) as $class)
      {

log_message('debug', "loader.php - _ci_load_class function - Upper/Lower array '$class' ");

$subclass = APPPATH.'libraries/'.$subdir.config_item('subclass_prefix').$class.EXT;

log_message('debug', "loader.php - _ci_load_class function - SUBCLASS NOW '$subclass' ");

// Is this a class extension request?
if (file_exists($subclass))
{

log_message('debug', "loader.php - _ci_load_class function - File Exists '$subclass' ");

$baseclass = BASEPATH.'libraries/'.ucfirst($class).EXT;
if ( ! file_exists($baseclass))
{
log_message('debug', "loader.php - _ci_load_class function - NOT File Exists 3 '$baseclass' ");
log_message('error', "Unable to load the requested class: ".$class);
show_error("Unable to load the requested class: ".$class);
}

The thing is - it HAS found file :- /home/sites/SITENAME/application/libraries/MY_Smarty_parser.php
But then /usr/local/lib/codeigniter/current/system/libraries/Smarty_parser.php is NOT found.

Why test for both of them if its going to fail on the 2nd one anyway ??  Shouldn’t Codeigniter just test the 2nd one first & get it over with ?

(I’ll copy it over & try again )

I think you are digging yourself in to the point where the pit is to deep to get out of.

Stick to the way Codeigniter works, and don’t try to come up with strange setups, and then wonder why it doesn’t work. Do not touch anything in system. Do not install anything there.

How you should install Smarty:
- create a directory called ‘smarty’ in application/libraries. Install Smarty in there.
- create a library called ‘smarty_parser’ in application/libraries:

<?php
require_once 'smarty/Smarty.php';

class Smarty_parser extends Smarty
{
    // do your thing here
}

- load it like a normal library and you’re in business.
