PHP - Making Configuration Changes In Joomla

Every now and then, I experience some strange behavior and eventually trace it back to parse_ini_file's scanner_mode being applicable to some parameter but not another, and am looking for alternatives.  Below are several of my thoughts.  How do you store configuration settings?  Do you use different approaches based on the application, and if so what criteria governs which you use?

Keep with a ini file with parse_ini_file.  Obviously, not working for me. An ini file but with a class dedicated to ensuring the data is appropriate.  Seems like too much duplicating content which will result in errors. YAML.  Don't think I want to. XML.  Not as readable. In a database.  Maybe, but might be harder to manage. Hardcode an array in PHP.  Probably not. JSON.  I like the idea, but feel comments are important in a config file, and am considering the following: Add extra valid JSON properties which contain comments.  Don't like the idea. Use JavaScript's JSON.stringify.  Too much mixing technologies. Add comments to the JSON and then strip them using a 3rd party parser such as https://json5.org/ or a little regex.  My main issue is inability to auto-format, but this seems viable. Any other ideas?

Thanks!

 

I have a configuration file, and I use parse_ini_file() to parse it into an array at the initial entry point of my script.   I would like the settings to be available to all downstream scripts/methods/functions. Note that my intent is not to change them outside of the configuration file, and ideally they will be readonly, however, if not, I suppose that is okay and I will just be sure not to modify them.   I've read about dependency injection, and while this mostly makes sense, it seems like a lot of script/troubleshooting for little if any value for this scenario.   I've read that global variables are bad (couples your objects to some "god" object, cannot unit test, difficult to troubleshoot, difficult to work with multiple developers, potential conflicts with other classes, namespace pollution), but maybe not for this case?   Another option is defining a bunch of constants to the appropriate values, but this seems redundant.   Or maybe some static class with all the values?   What would be the best way to make configuration settings available to all PHP scripts, functions, and methods?

Hi, I've been googling for a while now for an example of how to read, edit and write a configuration file.

This part was easy to find...
<?php
$icon_settings = parse_ini_file("test.desktop");
print_r($icon_settings);
?>

...the above code works great, but how do I edit and write back a configuration file like this...
Code: [Select]
#!/usr/bin/env xdg-open

[Desktop Entry]
Version=1.0
Name=Firefox Web Browser
Comment=Browse the World Wide Web
GenericName=Web Browser
Exec=firefox %u
Terminal=false
X-MultipleArgs=false
Type=Application
Icon=firefox
# ... and so on
back to the drive?

Thanks.

Hi,

I don't know if this is even possible, but I need to copy configuration of existing server to my localhost (using XAMPP on windows). I only have full output of phpinfo() function from that server (I don't have access to php.ini), and I would like to change my localhost server to behave exactly like remote one. 

Is this even possible? 
Is there some more "automatic" solution, than just going through bunch on lines of code and trying to change them?
Furthermore, remote server has much longer configure command, as well as list of additional .ini files parsed... how to change these?

Hey Guys,
First Post! Yay 
I have a problemo, I feel really stupid about having to ask this question. But basically I can't get a new line when I echo output in a script I am writing for my website.
Here is the code:
echo $newsentry;
echo '_______
Read More..';

I tried '\n' I tried using " (double quotes) I have used ' (single quotes) I have positioned the Line Feed '\n' at the begining of an output, and at the end. Neither made any difference. I tried using carriage return '\r' too. Nothing.
I haven't coded in PHP for a while, well nothing basic (I know that sounds rediculas but it has been mostly Apps etc, Client Scripts blah blah blah, but I haven't had to echo with a new line for a few years. Probably the last website which I wrote with my friend. So I checked the PHP manual, and I am clearly missing something when I am reading it, I understood it to mean (which as you can see from my code, is what I am currently doing), that you could just somehow type:
echo "some string
and it carries on to the second line";
However as I first thought, this makes no difference.
Could this be a configuration on the Box that hosts this Site??
Sorry for sounding so stupid guys, I appreciate your help.

Hello all, I have a question. The server I am currently working on is on PHP 5.2 and Joomla 1.5.26. I'd like to migrate or slowly move over to 3.0 on the same server however 3.0 requires at least 5.3 (would go to 5.4). In my cpanel, it tells me "PHP 5.4+ Incompatible Applications Installed". Is it not possible to run Joomla 1.5 on PHP 5.4, or are there certain components/modules that do not work with it?   The two major third party components I have installed are Community Builder and Jumi.   I just don't want my site to explode if I click the button.   Thanks, Rob

Hi

I am trying to knock up a script to create a userid and log someone into a Joomla based site. The script is running on the same server as the site (and is legitimate, not nefarious).

I can create an ID OK, and I can retrieve the login page, scrape the details (including the token) and submit the form.

When I do this the user is logged in according to the Joomla sessions table, but it has also created a 2nd guest session there. Navigating to the Joomla site (either manually or doing a header redirect) just takes you to the site as though you are not logged in.

Code as it stands (and code to deal with being passed user ids and passwords will change to be at least vaguely secure, just trying to get things to work now)

Hey guys,

Anyone who's used Joomla will know they have a very snazzy system for allowing the user to reorder the "order" field in any given table. You know the one, the blue arrows pointing up and down to move the row up or down.

I wanna implement something similar in my own sites CMS, does anyone know a good script to handle it?

Hi there, I have decided using the Joomla API however, the documentation was for 1.5 and 2.5 system only but i'm using 3.0. I have a number of files that look like this: "14-05-14 JoePharnel.pdf" and "13-05-12 HarryCollins.pdf" Basically I want to create a PHP code that when someone ftp uploads those files to the upload folder that it will 1) Create a directory if it doesn't exist using there name 2) Move the files to the correct directory (E.g. JoePharnel to the JoePharnel Directory ignoring the number at the beginning) My new code creates the folder but won't move the file in the upload into that new folder, code is below: <?php

define( '_JEXEC', 1);

define('JPATH', dirname(__FILE__) );

if (!defined('DS')){
define( 'DS', DIRECTORY_SEPARATOR );


$parts = explode( DS, JPATH );
$script_root = implode( DS, $parts ) ;

// check path
$x = array_search ( 'administrator', $parts );
if (!$x) exit;

$path = '';

for ($i=0; $i < $x; $i++){
$path = $path.$parts[$i].DS;
}
// remove last DS
$path = substr($path, 0, -1);

if (!defined('JPATH_BASE')){
define('JPATH_BASE', $path );
}

if (!defined('JPATH_SITE')){
define('JPATH_SITE', $path );
}

/* Required Files */
require_once ( JPATH_SITE . DS . 'includes' . DS . 'defines.php' );
require_once ( JPATH_SITE . DS . 'includes' . DS . 'framework.php' );
require_once ( JPATH_SITE . DS . 'libraries' . DS . 'joomla' . DS . 'factory.php' );


//Import filesystem libraries. Perhaps not necessary, but does not hurt

jimport('joomla.filesystem.path');
jimport('joomla.filesystem.file');
jimport('joomla.filesystem.folder');
jimport('joomla.user.user');



//First we set up parameters
$searchpath = JPATH_BASE . DS . "upload";





//Then we create the subfolder called png
if ( !JFolder::create($searchpath . DS ."Images") ) {
//Throw error message and stop script
}

//Now we read all png files and put them in an array.
$png_files = JFolder::files($searchpath,'.png');

//Now we need some stuff from the JFile:: class to move all files into the new folder
foreach ($png_files as $file) {
JFile::move($searchpath. DS . ".png" . $file, $searchpath . DS. "Images" . $file);
}

//Lastly, we are moving the complete subdir to the root of the component.
if (JFolder::move($searchpath . DS. "Images",JPATH_COMPONENT) ) {
//Redirect with perhaps a happy message
} else {
//Throw an error

}
}


?> Only error i get is Notice: Use of undefined constant JPATH_COMPONENT - assumed 'JPATH_COMPONENT' in /upload.php on line 70.  I have used and adapted multiple php code so any help would be appreciated. Or if you can point me to where i can find the answer that would be brilliant

Hello,

I'm trying to implement a custom css style for each of the K2 templates.   I wrote a com_K2 override.   I add this string to a K2 template php files

<link rel="stylesheet" href="<?php echo $this->baseurl ?>/templates/<?php echo $this->template; ?>/html/com_k2/templates/default/k2c.css" type="text/css" />

but it adds itself in the body of the page. Is there a way to put this string into <head> tag?   I'm not savvy in PHP, so any advice would be appreciated

I'm using the J2Store add-on for Joomla.  The store prints out a invoice and I am editing what prints out.  Right now it prints out each item ordered and the 'options' with that item.  (Ex. You can order a Large shirt the options are its a t-shirt and blue.)    What I'm trying to do is make a list of all the material ('options') and quanities in each order.   Below is the section of code I have been working with.  I added '<?php echo count($item); ?>' to the code but it just lists the 'options' then a 1 after, but only for one item in the order.   The J2Store support told me this: " first you need to decode the $item->orderitem_attributes
Then you need to parse through the array and get the options in a required format by sorting and using multiple loops. Then count each option. Example count($array['large']); "

    <?php if(!J2StoreOrdersHelper::isJSON(stripslashes($item->orderitem_attribute_names))): ?>

                            <?php if (!empty($item->orderitem_attribute_names)) : ?>
                                <span><?php echo $item->orderitem_attribute_names; ?></span>
                            <?php endif; ?>
                        <br />
                        <?php else: ?>
                        <!-- since 3.1.0. Parse attributes that are saved in JSON format -->
                        <?php if (!empty($item->orderitem_attribute_names)) : ?>
                            <?php
                                //first convert from JSON to array
                                $registry = new JRegistry;
                                $registry->loadString(stripslashes($item->orderitem_attribute_names), 'JSON');
                                $product_options = $registry->toObject();
                            ?>
                                <?php foreach ($product_options as $option) : ?>
                                - <small>
                                    <?php echo JText::_($option->name); ?>: <?php echo JText::_($option->value); ?>
                                        
                                        <?php echo count($item); ?>

                                    <?php if(isset($option->option_sku) && JString::strlen($option->option_sku) > 0):?>
                                        (<?php echo JText::_('J2STORE_SKU'); ?> : <?php echo $option->option_sku; ?>)
                                    <?php endif; ?>
                                </small><br />
                               <?php endforeach; ?>
