Tips & Tricks using Joomla Content Management System

Here are some useful Joomla tips and tricks:

1. Insert javascript or css styles

Sometimes we want to insert a small script to change the appearance of the web a little, for testing, version 3.3.6 is already opened by Joomla by default, but for older versions we need to activate it, here are the steps to enable script input: a. Click System -> Global Configuration, then select the Text Filter tab b. Determine the user group that will be given access to write scripts, there are several options, namely Default Black List, Custom Black List, White List, No HTML, and No Filtering. c. Select No Filtering for the Super User group No Filtering Joomla d. Click Save & Close. e. By default the editor used is TinyMCE, TinyMCE will automatically filter 3 tags, namely: script, applet, iframe. You can delete the filter but it is not recommended if there are several users because each user can insert certain codes that are harmful to website security. Click Extensions -> Plugin Manager, type in the search box tinymce click to configure TinyMCE In addition to disabling filters in the TinyMCE editor, there is a second way, namely changing the editor tool for certain users Click Users -> User Manager, edit the Super User account, change the Editor parameter to Editor – CodeMirror, then click Save & Close e. After you finish configuring, you can try to input javascript or css script in Article, click Content -> Article Manager -> Add New Article.

2. Overrides Template

By default the captcha plugin is not active, to activate it, you can open it in Extensions -> Plugin Manager, type in recaptcha search, then click Enable to activate it. Then edit the recaptcha.php file in the plugins/captcha/recaptcha folder on line 24 replace the code below

const RECAPTCHA_API_SERVER = "http://api.recaptcha.net";
const RECAPTCHA_API_SECURE_SERVER = "https://www.google.com/recaptcha/api";

menjadi

const RECAPTCHA_API_SERVER = "http://www.google.com/recaptcha/api";
const RECAPTCHA_API_SECURE_SERVER = "https://www.google.com/recaptcha/api";
const RECAPTCHA_VERIFY_SERVER = "www.google.com";

pada line 118 ganti code dibawah

dengan

$response = $this->_recaptcha_http_post(self::RECAPTCHA_VERIFY_SERVER, "/recaptcha/api/verify",

Kemudian aktifkan Default captcha di System -> Global Configuration menjadi Recaptcha

4. Protect administrator folder with .htaccess

Protect the administrator folder from various attacks by providing login protection, here are the steps: a. Create a .htpasswd password file and place it outside the public_html folder for example the home folder and enter the following password code: admin:24IQa4hXAaLKA The code is the password for “handsome” If you want to generate a different password in .htpasswd format, you can use the site http://www.mreriksson.net/online/htgenerator/ b. Create an .htaccess file in the administrator folder of the Joomla root and enter the following code:

 <Files .htaccess>
 order allow,deny
 deny from all
 </Files>
 AuthType Basic
 AuthUserFile /home/.htpasswd
 AuthGroupFile /dev/null
 AuthName "Joomla Administrator Area"
 <Limit GET POST>
 require valid-user
 </Limit>

Now try to access the administrator folder, you are required to login first before you can access the Joomla login.
