Example with l of in drupal

l('TITLE','node/33');

Output:
<a href="/?q=node/33">TITLE</a>

l('TITLE','node/33',array('attributes'=>array('target'=>"_blank")));

Output :
<a href="/?q=node/33" target="_blank">TITLE</a>

l('TITLE','node/33',array('query'=>array('disp'=>4),'attributes'=>array
('target'=>"_blank")));

Output :
<a href="/?q=node/33&disp=4" target="_blank">TITLE</a>

l('TITLE','node/33',array('attributes'=>array('target'=>"_blank")),'fragment'=>'comment-
1');

Output :
<a href="/?q=node/33#comment-1" target="_blank">TITLE</a>

l('TITLE','node/33',array('query'=>array('disp'=>4),'attributes'=>array
('target'=>"_blank")),'fragment'=>'comment-1');

Output :

Language translation for Drupal JavaScript files.

1. Make sure that you have entered Drupal.t () function before all the text.
2. You have to create a js file (fr-trans.js) like below u for corresponding language
Drupal.locale = {‘strings’: {"Certification":"Certification","Required":"Requis"}};
In my example I have given for French language.
3. Include the js file based on user language

Language translation in Drupal Based on user language or based on website

1. Make sure that you have entered t() function before all the text.
2. Install the locale module.
3. In admin settings to Languages Link add languages which you need.

Path prefix with language fallback. "(You have to do this if you want language translation
based on user selected language in his my account page) Or In admin setting languages Click the default language for the webpage to change page to corresponding language(This will change the language of webpage)
5. Download the default po file provided by drupal from this link
http://localize.drupal.org/ for testing purpose. (Note: You need to create a po file
based on your content of you website )
6. Go to Translate interface link in site building
7. Click on the import link & select the language & import the selected language po file
8. Check for a particular user by changing his language

Put a pipe symbol in between primary link

1.Pu this code in the template.php file of your theme folder
2.Check the class of primary links in the page.tpl or page-front.tpl matches with class condition check indie this function if this function doesn't work

function youthemename_links($links, $attributes = array('class' => 'links')) {
$output = '';

}
// Return the links joined by a '|' character
return join(' | ', $linklist);
}
// Normal theming continued below:

if (count($links) > 0) {
$output = '<ul'. drupal_attributes($attributes) .'>';

$num_links = count($links);
$i = 1;

foreach ($links as $key => $link) {
$class = $key;

// Add first, last and active classes to the list of links to help out themers.
if ($i == 1) {
$class .= ' first';

$class .= ' last';
}

$class .= ' active';
}
$output .= '<li class="'. $class .'">';

if (isset($link['href'])) {
// Pass in $link as $options, they share the same keys.
$output .= l($link['title'], $link['href'], $link);
}
else if (!empty($link['title'])) {
// Some links are actually not links, but we wrap these in for adding title and class attributes
