未为 Joomla 类别自定义组件保存标签

Question

I am developing a Joomla component and using the categories from the joomla Core. The categories are saving properly in the Joomla Administration, but I can't add tags to this categories.. Am I doing something wrong? Or do I need specific code to add tags to the categories for my component?

Answer 1

You need to add an entry in the content type table if you want to add tags support in the category. More Detail

Below is the example code that you can check for refrence to add an entry into content type table. Change com_example to your extension.

<?php
/** @var JTableContentType $table */
$table  = JTable::getInstance('contenttype');

if ($table)
{
    $table->load(array('type_alias' => 'com_example.category'));

    if (!$table->type_id)
    {
        $data   = array(
            'type_title'        => 'Example Category',
            'type_alias'        => 'com_example.category',
            'table'             => '{"special":{"dbtable":"#__categories","key":"id","type":"Category","prefix":"JTable","config":"array()"},'
            . '"common":{"dbtable":"#__ucm_content","key":"ucm_id","type":"Corecontent","prefix":"JTable","config":"array()"}}',
            'rules'             => '',
            'field_mappings'    => '
            {"common":{
            "core_content_item_id":"id",
            "core_title":"title",
            "core_state":"published",
            "core_alias":"alias",
            "core_created_time":"created_time",
            "core_modified_time":"modified_time",

            "rgt":"rgt",
            "level":"level",
            "path":"path",
            "extension":"extension",
            "note":"note"
            }
            }',
            'content_history_options' => '{"formFile":"administrator\/components\/com_categories\/models\/forms\/category.xml",
            "hideFields":["asset_id","checked_out","checked_out_time","version","lft","rgt","level","path","extension"],

            "ignoreChanges":["modified_user_id", "modified_time", "checked_out", "checked_out_time", "version", "hits", "path"],

            "convertToInt":["publish_up", "publish_down"],
"displayLookup":[{"sourceColumn":"created_user_id","targetTable":"#__users","targetColumn":"id","displayColumn":"name"},
            {"sourceColumn":"access","targetTable":"#__viewlevels","targetColumn":"id","displayColumn":"title"},
            {"sourceColumn":"modified_user_id","targetTable":"#__users","targetColumn":"id","displayColumn":"name"},
            {"sourceColumn":"parent_id","targetTable":"#__categories","targetColumn":"id","displayColumn":"title"}]}',
        );

        $table->bind($data);

        if ($table->check())
        {
            $table->store();
        }
    }
}

For anyone facing the same issue I solved it after going through lot of pain. There is no documentation on this if you are using Joomla categories in your component. @irfan was correct but to make it more easy I feel you can just add a row to the #__content_types during installation itself. What I did was I just searched com_newsfeed row in joomla database. I came across a newsfeed categories inside #__content_type . I replaced the type_title column to my title and type_alias column to my_extension.category . And I was able to save the tags. Also router column names to be changed to your router. Whole SQL code which you need to put inside your sql file is

INSERT INTO `#__content_types` (`type_title`, `type_alias`, `table`, `rules`, `field_mappings`, `router`, `content_history_options`) VALUES

('Your Category', 'com_yourcomponent.category', '{"special":{"dbtable":"#__categories","key":"id","type":"Category","prefix":"JTable","config":"array()"},"common":{"dbtable":"#__ucm_content","key":"ucm_id","type":"Corecontent","prefix":"JTable","config":"array()"}}', '', '{"common":{"core_content_item_id":"id","core_title":"title","core_state":"published","core_alias":"alias","core_created_time":"created_time","core_modified_time":"modified_time","core_body":"description", "core_hits":"hits","core_publish_up":"null","core_publish_down":"null","core_access":"access", "core_params":"params", "core_featured":"null", "core_metadata":"metadata", "core_language":"language", "core_images":"null", "core_urls":"null", "core_version":"version", "core_ordering":"null", "core_metakey":"metakey", "core_metadesc":"metadesc", "core_catid":"parent_id", "core_xreference":"null", "asset_id":"asset_id"}, "special":{"parent_id":"parent_id","lft":"lft","rgt":"rgt","level":"level","path":"path","extension":"extension","note":"note"}}', 'YourComponentHelperRoute::getCategoryRoute', '{"formFile":"administrator\\/components\\/com_categories\\/models\\/forms\\/category.xml", "hideFields":["asset_id","checked_out","checked_out_time","version","lft","rgt","level","path","extension"], "ignoreChanges":["modified_user_id", "modified_time", "checked_out", "checked_out_time", "version", "hits", "path"],"convertToInt":["publish_up", "publish_down"], "displayLookup":[{"sourceColumn":"created_user_id","targetTable":"#__users","targetColumn":"id","displayColumn":"name"},{"sourceColumn":"access","targetTable":"#__viewlevels","targetColumn":"id","displayColumn":"title"},{"sourceColumn":"modified_user_id","targetTable":"#__users","targetColumn":"id","displayColumn":"name"},{"sourceColumn":"parent_id","targetTable":"#__categories","targetColumn":"id","displayColumn":"title"}]}')

Note : remember to change the component name in the code. I have given an example code.
