1. File paths in Joomla templates and components should use forward slashes instead of DS to separate directories for readability and compatibility across operating systems. 2. PHP files should not include a closing PHP tag at the end to avoid corrupting JSON or HTTP headers. 3. Components and templates should be tested with debug and SEF URLs turned on to avoid issues when these settings are enabled.

1. 10 things you are doing
Wrong in joomla

2. 1. file paths
require_once JPATH_SITE.DS.'components'.DS.'com_community'.DS.'helper.php'
Looks ugly. It needn't. You can use this without worrying about
Linux/Windows/mac compatibility
require_once JPATH_SITE.'/components/com_community/helper.php'
This is perfectly fine and much readable. Also easier to write

3. 2. Closing php files
<?php
$my = Jfactory::getUser();
?>
Avoid adding a closing php tags at the end of the file. You can
corrupt json output or other headers
<?php
$my = Jfactory::getUser();
?>
<?
$db = Jfactory::getDBO();
// no closing PHP tag

4. 3. testing without debug & sef
Otherwise you might have nightmare when you
turn these on!
●
No warnings/notices
●
No database query issues
●
Custom components work with sef urls

5. 4. hacking core files
Obvious.. duh ? Override!
I know it's obvious but sometimes the temptation
to hack is just too much and needs to be
avoided.

6. 5. directly using get / post
Use jinput. Period.
<?php
$input = JFactory::getApplication()­>input;
$option = $input­>get('option');

7. 6. directly editing language
overrides
there's an overrides manager for that in the
joomla admin!

8. 7. not adding cache, suffix and other
module params
They're there for a reason!
Cache - suffix – bootstrap size – alternate layout
and there's a few more

9. 8. multiple jquery
8. multiple jquery
I hope this was clear enough ?
8. multiple jquery

10. 9. Writing sql queries directly
$query = “SELECT id, name FROM #__users”;
If ($username) {
$query .= ' username='.$db­>Quote($username);
This is how dummies do it -
Smart kids do it smart -
$query = $db­>query();
$query­>select('id,name');
$query­>from('#__users');
If ($username) {
$query­>where('username='.$db­>Quote($username));

11. 10. large js & css
