PHP - Joomla - Moving A Module By Changing Its Coded Location

I can't seem to find a tutorial on basics of making a module based php system. Like how to fetch and execute the module. 

This is a node voting module I created and it has a slight problem that I cannot figure out.
It's supposed to be a simple 'Vote Up' or 'Vote Down' feature. You click 'Vote Up' and one appears in your vote tally. You click 'Vote Down' and your original vote tally is subtracted by one back down to zero.

When it goes back to zero, it gets stuck there. It stays on zero no matter if I choose 'Vote Up' or 'Vote Down' again.

There's something that's happening when I move my vote tally back down to zero. Maybe something isn't setup correctly with the $current_votes variable. I don't know.

I've been at this for hours. Here's the code:

<?php

function bonnier_vote_perm() {
  return array('vote on content');
}

function bonnier_vote_menu() {
  $items = array();
  $items['vote'] = array(
    'title' => 'vote',
    'page callback' => 'bonnier_vote_vote',
    'access arguments' => array('vote on content'),
    'type' => MENU_CALLBACK,
  );
  return $items;
}

function bonnier_vote_vote() {
  $nid = $_REQUEST['nid'];
  $value = $_REQUEST['votes'];
  
  $current_votes = db_result(db_query("SELECT votes FROM bonnier_vote WHERE nid = $nid"));
  
  if ($current_votes) {
    $new_votes = $current_votes + $value;
    db_query("UPDATE bonnier_vote SET votes = $new_votes WHERE nid = $nid");
  }
  else {
    db_query("INSERT INTO bonnier_vote (nid, votes) VALUES ($nid, $value)");
  }
  
  drupal_set_message('Your vote has been recorded');
  drupal_goto('node/'.$nid);
}

function bonnier_vote_nodeapi(&$node, $op, $teaser = null, $page = null) {
  if ($op == 'view' && !$teaser) {
    $votes = db_result(db_query("SELECT votes FROM bonnier_vote WHERE nid = {$node->nid}"));
    if (!$votes) {
      $votes = 0;
    }
    
    $widget  = '<div>';
    $widget .= l('Vote Up', 'vote', array('query' => array('nid' => $node->nid, 'votes' => 1)));
    $widget .= ' ';
    $widget .= l('Vote Down', 'vote', array('query' => array('nid' => $node->nid, 'value' => -1)));
    $widget .= ' ';
    $widget .= 'Sco  '. $votes;
    $widget .= '</div>';
    
    $node->content['vote_widget'] = array(
      '#value' => $widget,
      '#weight' => -10,
    );
  }
}

Any bit of advice would be much appreciated.

How do I check in PHP if something like the GD library is installed on a server? I am going to be making a thumbnailing system and the user can install the app on their server. If they have the GD library, continue with making thumbnails, else show a default thumbnail.

Hello,   First time asking technical question in a forum so I beg pardon for errors.   I have a third party blog module installed on opencart. The original coder helped me to fix some bugs, but he is not answering anymore to emails. I would like to add a simple pagination to the "latest articles"  part, because at the moment the website display the exact number declared in "article limit" and does not show pagination if articles shown are less than the total.   the code from "article_by_type.php" line 85  is the following:

/*recent_article*/

        if ($setting['article_type']=='recent_article') {

        $data = array(

                    'sort'  => 'p.date_added',

                    'order' => 'DESC',

                    'start' => 0,

                    'limit' => $article_limit

                );

        

                $articles = $this->model_news_article->getArticles($data);

        }

another file "article_list.php" at line 88 and 214 already have pagination:  

$this->data['article_ajax_load'] = $this->getArticle($article_category_id,$page,$limit,$description_limit);

                    

            $pagination = new Pagination();

            $pagination->total = $article_total;

            $pagination->num_links = 3;

            $pagination->page = $page;

            $pagination->limit = $limit;

            $pagination->text = $this->language->get('text_pagination');

            $pagination->url = 'index.php?route=module/article_list/getlist&cpath='.$article_category_id. '&page={page}'.'&limit=' .$limit;

        

            $this->data['pagination'] = $pagination->render();

  can anyone help add pagination to "article_by_type.php" or adapt the existing pagination code to it ? Attached Files  article_by_type.php   6.23KB   0 downloads  article_list.php   10.2KB   0 downloads

hello dear linux-community

if a server needs to meed some requirements - eg for installation wordpress and if the server needs to run

eg see he   https://wordpress.or...t/requirements/

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 ,   My site gives a blank page when i click on an article due to insufficient memory. I tried making changes to the php.ini file but the changes are not getting reflected.   Please advice if a server restart is needed for this, how do i go about it?   Thanks in advance

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

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); ?>

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

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)
