Tilt is a Firefox addon that lets you visualize any web page in 3D.

I instaled it today. It seems to be very helpful to understand webpage structure in addition to Firebug.

I expanded the class XoopsFormSelect for my needs, but may also be useful to someone.
I needed to color a few items in the select list. Of course you can use javascript. In this case it was convenient for me to modify the methods of the class (only addOption, addOptionArray not). In Xoops 2.2.x was also able to option disabled, so I added it too.
use
For example in. css
php
result:
NOTICE: This is just an example of Firefox. Different browsers interpret style for <option> in different ways. IE displays only the text colors.
By the way. Why in the method getOption() is sanitized when render() forced to htmlspecialchars.

Better solution - use OOP: extend original class XoopsFormTextDateSelect and add parameter $autofill
Moreover this class accepts English textual datetime description and convert it into a timestamp (seehttp://php.net/manual/en/function.strtotime.php).
Example, this displays a later date by one day:
Empty field:
class pfFormTextDateSelect extends XoopsFormTextDateSelect
{
/**
* Constructor
*
* @param string $caption Caption
* @param string $name "name" attribute
* @param int $size Size
* @param int,string $value Initial date (timestamp format) or English textual datetime description which can be converted to timestamp (see: strtotime PHP function)
* @param bool $autofill If $value is empty or not recognized textual datetime the form field filled current date ($autofill = true) or leave empty
*/
function pfFormTextDateSelect($caption, $name, $size = 15, $value = 0, $autofill = true)
{
// previous to PHP 5.1.0 you would compare with -1, instead of false
if ( strtotime($value) !== false OR strtotime($value) != -1 ) {
$value = strtotime($value);
}
if ( $autofill === true ) {
$value = !is_numeric($value) ? time() : intval($value);
$value = ($value == 0) ? time() : $value;
}
else {
$value = !is_numeric($value) ? '' : intval($value);
$value = ($value == 0) ? '' : $value;
}
$this->XoopsFormText($caption, $name, $size, 25, $value);
}
}
Moreover this class accepts English textual datetime description and convert it into a timestamp (seehttp://php.net/manual/en/function.strtotime.php).
Example, this displays a later date by one day:
new pfFormTextDateSelect('', 'test', 10, '+1 day', false);
Empty field:
new pfFormTextDateSelect('', 'test', 10, '', false);

NOTICE: This my function from above doesn't work since Xoops 2.5.4. There were changes in xoops calendar and the file: /include/calendarjs.php even not exist in the latest Xoops.

Look into /kernel/object.php
XoopsPresistentObjectHandler has the same methods (and many more) like XoopsObjectHandler. But "fill" them with code.
I'm using only XoopsPresistentObjectHandler, so I do not know if XoopsObjectHandler is useful to something.
I have an other dummy question what is the diffrence between XoopsObjectHandler and XoopsPresistentObjectHandler?

setDescription method works only for individual form elements
Example for text type input:
Example for text type input:
$page_banner = new XoopsFormText( _AM_SYSTEM_BANNERS_CONTNAMET, 'banners', 5, 5, $this->getVar( 'banners', 'e' ) );
$page_banner->setDescription( _AM_SYSTEM_BANNERS_CONTNAMET_DESC );
$form->addElement( $page_banner );

Great (but simple) article about PNG format.
PNG supports various combinations of color depth, transparency and color correction. Some combinations work perfectly with every piece of software, and some are practically useless.

You can also add this to file ckeditor/module/config.oledrion.js (it's placeholder for module specific configurations in CKEditor). In case when updating CKEditor file ckeditor/config.js will be replaced by the original one.

The biggest difference between smarty 2 and 3 is that the S3 has been completely rewritten in PHP5. S3 placed great emphasis on backwards compatibility, so apart from the fact that it will not work on php4 there should be no other problems. But therefore not expect great changes in speed. Smarty 3 is not a revolution.
PS. Looking for information on Smarty landed onhttp://dwoo.org/ project. It seems that it is compatible with smarty but is more advanced. Not tested, showing only as a curiosity ;)
