Hello,

I've been developing an application in my Windows box (localhost) and now I'm trying to put the application in a Linux server. And of course, I'm having problems...

When I started to develop in windows, I did some configurations to make things work, but in the end was all ok. I used XAMPP.

Now something is wrong and I think is something to do with Apache configuration. I followed this steps: http://codeigniter.com/wiki/mod_rewrite/ to take off the index.php and I can open the application. But when I try to do something on it, simple don't work...

When I do:

Code:
a2enmod

and then

Code:
rewrite

I got the message: 'Module rewrite already enabled', which is good...

If I do:

Code:
apache2ctl -l

I got:

Code:
Compiled in modules:

  core.c

  mod_log_config.c

  mod_logio.c

  prefork.c

  http_core.c

  mod_so.c

Which of this is the mod_rewrite?
Oh, and by the way, the file mod_rewrite.so shouldn't be present in /etc/lib/apache2/modules? Because it's not there!

Any of you can help me?

Code:
apache2ctl -l

This only shows the modules that have been compiled with apache. They don't give you all the loaded modules.

Try:

Code:
apache2ctl -t -D DUMP_MODULES

Hello, and thanks for your reply.
I can see that mod_rewrite is active:

Code:
rewrite_module (shared)

But I'm experience something strange and I'm not sure if is because of the .htaccess file.
For example, when I enter my application, I have this in my main page:

Code:
<a href="main/login"><div style="margin: 10px">&lt;?php echo snappy_image('twitter_button_3_hi.gif', '', ''); ?&gt;</div></a>

So, this is just a call to the controller main and to the function login

I changed the login function code, just for tests and now I have just this:

Code:
function login(){

  $this->load->view('teste_view');

}

So, this is just a call to a view that contains the following code:

Code:
&lt;html&gt;

  &lt;head&gt;

    &lt;title&gt;Test&lt;/title&gt;

  &lt;/head&gt;

  &lt;body&gt;

    <h1>Hello!</h1>

  &lt;/body&gt;

&lt;/html&gt;

So, just a pretty basic html page. And when I press the link, the browser goes to:

Code:
http://somedomain.co.uk/project/main/login

And this is correct. But, the problem is, when I press the link, the application just open an empty (blank) page!
Any of know what could be the problem?

My .htaccess file is like this:

Code:
<IfModule mod_rewrite.c>

    RewriteEngine On

    RewriteBase /project/

    RewriteCond %{REQUEST_URI} ^system.*

    RewriteRule ^(.*)$ /index.php/$1 [L]

    RewriteCond %{REQUEST_URI} ^project.*

    RewriteRule ^(.*)$ /index.php/$1 [L]

    RewriteCond %{REQUEST_FILENAME} !-f

    RewriteCond %{REQUEST_FILENAME} !-d

    RewriteCond $1 !^(index\.php|images|stylesheets|system/application/sources/)

    RewriteRule ^(.*)$ index.php/$1 [L]

</IfModule>

<IfModule !mod_rewrite.c>

    ErrorDocument 404 /index.php

</IfModule>

AddHandler x-httpd-php5 .php .php3 .php4 .phtml # phpvs v5

(My project is in /var/www/project)

I'm using:

Code:
$config['uri_protocol'] = "PATH_INFO";

Because I'm using this library.

This is the .htaccess file I use in my Windows box, and everything is working good and the httpd.conf file in my Apache (with XAMPP) is like:

Code:
<Directory "C:/Program Files/XAMPP/htdocs">

  Options Indexes FollowSymLinks Includes ExecCGI

  AlowOveride All

  Order allow, deny

  Allow from all

</Directory>

In the Linux box I have (in /etc/apache2/sites-enabled/000-default):

Code:
<Directory /var/www/>

  Options Indexes FollowSymLinks Includes ExecCGI

  AllowOverride All

  Order allow,deny

  Allow from all

</Directory>

So, they are the same... Just one more note: I'm using twitter, as you can see. To do this I had to create a twitter application with a URL callback. The thing is, this url is like:

Code:
http://somedomain.co.uk/project/main/login

But I'm running the application localhost, so I added the following lines to my hosts file:

Code:
127.0.0.1       somedomain.co.uk

localhost       somedomain.co.uk

I have the same thing working in the Windows box.

Apache log:

Code:
Mon Jun 14 10:26:48 2010] [error] [client 127.0.0.1] PHP Fatal error:  Call to undefined function view() in /var/www/project/system/application/controllers/main.php on line 28, referer: http://somedomain.co.uk/project/index.php

You know what is going on?

Code:
Mon Jun 14 10:26:48 2010] [error] [client 127.0.0.1] PHP Fatal error:  Call to undefined function view()

It seems like it doesn't show the view because it the view function doesn't exist. Seems to me like Apache is working fine: the blank page is because of this error. If you turn error reporting on it should display this message instead of giving a blank page. Maybe you should turn on error logging in CI and see what's going on. Seems like something isn't setup right. Are you sure the permissions are set correctly?

Hey man, thanks again.

I figured out what is the problem, but looking for a way to solve it.

Basically I have a desktop computer with windows and a laptop with ubuntu Linux. In both the application is running ok, but when I move the application to the main server (with Linux too) the application have a strange behavior.

And that happens because I'm using Haughins library to get info from twitter and this info comes in json format. In my both computers I get a json response, but in the server, I get the full page (html) as response, and this makes the application with that behavior.

This means that the server donw access to my index.php file? Actually I did this in my application: http://codeigniter.com/wiki/mod_rewrite/

Any suggestions?

Hello again,

I spent the last 5 days trying to make this shit work, and till now nothing... This is the first time such thing happen to me and I'm really desperate...

When I put the files in the server, and after configure all the paths, the application runs. But when I try to do something, nothing works, cause instead of json I'm getting html and I don't know why. And, as I told you before, in my laptop (with linux) and in my desktop (with windows) everything is ok.

One example I have is like:

Code:
&lt;input type="submit" value="" class="search" id="search" name="search" /&gt;

(in a view)

and I'm doing some stuff in jquery:

Code:
(document).ready(function(){

    $('#search').click(function(){

       alert('test');

    });

});

(in .js file)

If I press the button I get the window with 'test', so this means that jquery and my .js file are being loaded (as firebug say).

But if I have the code:

Code:
(document).ready(function(){

    $('#search').click(function(){

       $.post("home/search", {"search": item},

            function(data){

              alert(data);   

            },"json");

    });

});

I'm just trying to call the function search inside home controller.

Im my controller I have just:

Code:
function search(){

   $array = array('result' => 'teste');

   $this->firephp->info($array);

}

But this is never executed.
In Firebug I can see that I'm having a response, but is not what should and the response is in HTML and should be in JSON...

None of you know wtf is going one? I kinds new to CI and I'm tired to try things and till now nothing...

Please help,

Thanks

Luis

It's possible that the "home/search" path is being seen as relative to the current url... I would try changing it to an absolute path to see if the code executes

Hello and thanks for your reply...

I tried that already and the result is exactly the same. I went to folder system/application/controllers, I did a pwd and I got:

Code:
/home/user/domains/somedomain.co.uk/public_html/system/application/controllers

and in the .js file I changed the code to:

Code:
(document).ready(function(){

    $('#search').click(function(){

       $.post("/home/user/domains/somedomain.co.uk/public_html/system/application/controllers/home/search", {"search": item},

            function(data){

              alert(data);   

            },"json");

    });

});

But the result is exactly the same. Sad

Any other suggestions?

Well, the fact that you're getting exactly the same result with the relative path and an obviously invalid path like the server path just confirms what I was thinking, the problem is an invalid path.

Use the absolute web path, eg. /home/search, or http://www.somedomain.co.uk/home/search

There is a $ before the (document) in your jquery, right?

Hey again, and thanks for your reply.

I was so desperate that what I did was starting to just copy and past the code to the server and see where will fail, and now I know what is wrong.

The problem is with this line:

Code:
$config['uri_protocol']    = "AUTO";

The thing is, to use the Elliot Haughin twitter API, I had to change:

Code:
$config['uri_protocol']    = "AUTO";

$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-';

to

Code:
$config['uri_protocol']    = "PATH_INFO";

$config['permitted_uri_chars'] = 'a-z? 0-9~%.:_\-';

And when I do that, the application stops working.
So, I suppose this is because some misconfiguration (or something missed) in the apache server, right? Can I change my .htaccess to make this work?

Thanks,

Luis Gonçalves
