[Solved] Category Blog error when set tag

[xuanhau]

In Joomla 3.8.1, if you create menu with category blog/list combine with tag item, you will have empty page with any category.

Solve:
Open the file components\com_content\models\category.php, Line: 244 ==> disable this line

Code: Select all

			
			$model->setState('list.direction', $this->getState('list.direction'));
			$model->setState('list.filter', $this->getState('list.filter'));
			//$model->setState('filter.tag', $this->getState('filter.tag'));

I solved this issue

That's not a valid 'solution' because that file will be overwritten when the core is updated. You'll need to write a plugin or a method using JModelLegacy in your template to achieve the goal and avoid overwrite.

Something like this (not a working method, just a clue where to search for a solution)

Code: Select all

JModelLegacy::addIncludePath(JPATH_SITE . '/components/com_content/models', 'ContentModel');
$model = JModelLegacy::getInstance('Articles', 'ContentModel', array('ignore_request' => true));
$app = JFactory::getApplication();
$myParams = $app->getParams();
$model->setState('params', $myParams);

I think this is the bug. Because of the code $this->getState('filter.tag') will get filter tag from menu to other menu.
If you create menu with default category and category menu with any tag. You will receive empty page after select tag category menu.

You can test in your side.
