How to get article text by article ID in Joomla?

问题:

I want to get article text by passing article ID from the joomla template.

回答1:

Simple, providing you sending an article id with post/get and using variable "id" as its number:

$articleId = JRequest::getInt('id');
$db =& JFactory::getDBO();

$sql = "SELECT fulltext FROM #__content WHERE id = ".intval($articleId);
$db->setQuery($sql);
$fullArticle = $db->loadResult();

if(!strlen(trim($fullArticle))) $fullArticle = "Article is empty ";

EDIT: to get articleId from anywhere:

$articleId = (JRequest::getVar('option')==='com_content' && JRequest::getVar('view')==='article')? JRequest::getInt('id') : 0;

try this technique:

$article = JControllerLegacy::getInstance('Content')->getModel('Article')->getItem($articleId);
echo $article->introtext;

Get article text by article ID in Joomla 2.5 (3 will work also according docs) plugins:

$article =& JTable::getInstance("content");
$article->load($id);
$content = '<h3>'. $article->get("title").'</h3>';
$content .= $article->get("introtext"); // introtext and/or fulltext

And article id is got from component/plugin parameters for example:

1. From inside own component:

   $app = JFactory::getApplication();
   $params = $app->getParams();
   $param = $params->get('terms_article_id');
   

2. From other component:

   $params = JComponentHelper::getParams('com_mycom');
   $id = $params->get('terms_article_id');
   

3. Get Module Parameter from template's php file:

   $module = JModuleHelper::getModule('mod_mymodule');
   $params = new JRegistry($module->params); // or $mymoduleParams if few used
   $id = (int) $headLineParams['count'];

Joomla has the default script for getting content from sql table.

Here article (#__content)

To Get Article Id:

$articleId = (JRequest::getVar('option')==='com_content' && JRequest::getVar('view')==='article')? JRequest::getInt('id') : 0;

To get Article content:

$table_plan         = & JTable::getInstance('Content', 'JTable');
$table_plan_return  = $table_plan->load(array('id'=>$articleId));
echo "<pre>";print_r($table_plan->introtext);echo "</pre>";
