• Joomla! 4 – The hope of promising year 2018
  in Joomla

  During 2017, we have heard a lot of opinions that this year has been too gloomy for Joomla. However, we think that this year is so important because it is the stepping stone for the explosion in 2018 when we prepare to welcome Joomla! 4.0 and Joomla! Framework 2.0. In addition to introducing several new features, including a fully rebuilt Media Manager, an enhanced event dispatching system, and new security features such as support for prepared SQL statements, we have also been doing some routine maintenance and paying off some of our project’s technical debt by retiring deprecated code and raising the minimum supported software stack. And, with this released version, we also require PHP 7.

• Unset Joomla Scripts from Template (k2 and other)
  in PHP

  // Unset unwanted Scripts - by name
  $unset_scripts = array(
  	'k2',
  	'...',
  );
  
  foreach($this->_scripts as $name=>$script)
  {
  	if (!preg_match('#(' . implode('|', $unset_scripts) . '#i', $name))
  	{
  		continue;
  	}
  
  	unset($this->_scripts[$name]);
  }

  or if you use joomla v3.8.1 you can try this php code:

  <?php
  	$doc = JFactory::getDocument();
  	unset($doc->_scripts[JURI::root(true) . '/media/system/js/mootools-more.js']);
  	unset($doc->_scripts[JURI::root(true) . '/media/system/js/mootools-core.js']);
  	unset($doc->_scripts[JURI::root(true) . '/media/system/js/core.js']);
  	unset($doc->_scripts[JURI::root(true) . '/media/system/js/modal.js']);
  	unset($doc->_scripts[JURI::root(true) . '/media/system/js/caption.js']);
  	unset($doc->_scripts[JURI::root(true) . '/media/jui/js/jquery.min.js']);
  	unset($doc->_scripts[JURI::root(true) . '/media/jui/js/jquery-noconflict.js']);
  	unset($doc->_scripts[JURI::root(true) . '/media/jui/js/bootstrap.min.js']);
  ?>

  if you wand disable all js & css scripts - use code:

  $doc->_scripts     = null;
  $doc->_script      = null;
  $doc->_styleSheets = null;
