Use ajax to upload files with javascript validation. Ajax is another word for fast and user friendly web pages.

Add the following code in the <head> of your webpage
<script type=”text/javascript”>
$(document).ready(function(){
$(”img”).bind(”contextmenu”,function(e){
return false;
});
});
</script>
I had used this on my drupal site in page.tpl file
I wanted a flashy scrollpane for the content on my drupal site.
I have drupal 5 where the scrollpane module is not available and I needed lightbox2 which required jquery_update module. Now the jscrollpane script clashed with compat.js of jquery_update module. So the solution for that is to download jscrollpane module for drupal 6. Take the jscrollpane.js file from this module and place it in your theme file.
To enable the jscrollpane use the following guidelines. I have implemented it manually.
In the page.tpl add the following css and javascript in the head:
<style type=”text/css” media=”all”>@import “<?php print base_path() . path_to_theme() ?>/styles/demoStyles.css”;</style>
<style type=”text/css” media=”all”>@import “<?php print base_path() . path_to_theme() ?>/styles/jScrollPane.css”;</style>
<script type=’text/javascript’ src=”<?php print base_path() . path_to_theme() ?>/scripts/jquery.mousewheel.js”></script>
<script type=’text/javascript’ src=”<?php print base_path() . path_to_theme() ?>/scripts/jScrollPane.js”></script>
<script type=”text/javascript”>
$(function()
{
// this initialises the demo scollpanes on the page.
$(’#pane3′).jScrollPane();
});
</script>
In the body put content inside div class=”scroll-pane” like the following:
<div id=”pane3″ class=”scroll-pane”>
<?php print $content; ?>
</div>
I got the stylesheets and scripts from jscrollpane official example link. And have used “#pane3″.
I am using webforms and I have three fields were either one of em should be filed.
Use the “additional validation” input box in the form “configuration”.
The code is following:
<?php
$book= $form_values['submitted'][11];
$author= $form_values['submitted'][12];
$isbn= $form_values['submitted'][13];
if (($book == NULL) AND ($author == NULL) AND ($isbn == NULL))
{
form_set_error(”, t(’Please enter either Book Title or Author or ISBN.’));
}
?>
The 11, 12 and 13 is the field id of your input fields. To find the field IDs mouse over the “edit” link next to your fields in the “Form Components”.

Create a separate stylesheet like style-rtl.css
Then in the page.tpl file instead of <?php print $styles?> variable use the following:
<?php
$rtl_langs = array(”ar”, “fa”, “he”, “ur”, “yi”); // There are a couple or so more. Put the codes of your RTL languages here
$is_rtl = in_array ($language, $rtl_langs);
if ($is_rtl) { // Check if the language of the current page is RTL.
/* Load RTL styles instead of default ones: */
foreach($css as $media => $types){
foreach($types as $type => $files){
foreach($files as $file => $preprocess){
$element = $file;
$rtl_style = str_replace(array (’modules’, ‘.css’),array (’sites/all/modules’,'-rtl.css’),$file);
if(file_exists($rtl_style)){
unset($css[$media][$type][$file]);
$css[$media][$type][$rtl_style] = $preprocess;
}
}
}
}
print drupal_get_css($css);
}
else {
print $styles;
}
?>
I need to redirect pages with .php extension to without. Like www.magrudy.com/mystore.php to www.magrudy.com/mystore
Use the following
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /([^/\ ]+/)*([^.\ ]+\.)+(php|html?)\ HTTP
RewriteRule ^(([^/]+/)*[^.]+)\.(php|html?)$ http://www.magrudy.com/$1 [R=301,L]

Make sure the website is not in maintenance mode 
took me atleast 20 mins to figure it out.
I had installed tweetmeme on my drupal website, it was working great on the content type ‘page’ but not on my customized content types like news and blog.
I spend hours finding the solution, going through all the complicated scenarios, cursing drupal, hating life etc and then as usual the solution was very easy and it hit in a second showing me the light in the dark tunnel and i declare my love for drupal again. Ok ok enough of gibberish the solution is mentioned below.
Contemplate was the answer. I had used contemplate for theming purposes, but after tweetmeme we have to add
<?php print $node->content['tweetmeme']['#value'] ?>
in the contemplate box.
Then make sure the website is not in maintenance mode, and voila you can see the beautiful green box saying ‘retweet’
Go to – admin – input formats
