You can manage display of primary menu links from your template.php file. If you have used theme(”links”,”$primary_links,array(”class”=>”primary menu”)); Then you can preprocess links from template.php in following manner.

/**
* * @global <type> $language
* @param <type> $links
* @param <type> $attributes
* @return <type>
*/
function phptemplate_links($links, $attributes = array(’class’ => ‘links’)) {
global $language;
$output = ”;

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) {
$class .= ‘ first’;
}
if ($i == $num_links) {
$class .= ‘ last’;
}
//print_r($link['href'].”<br/>”);

if(arg(0)==$link['href']){
$class .= ‘ active-trail’;
}
if (isset($link['href']) && ($link['href'] == $_GET['q'] || ($link['href'] == ‘<front>’ && drupal_is_front_page()))
&& (empty($link['language']) || $link['language']->language == $language->language)) {
$class .= ‘ active’;
}
$output .= ‘<li’. drupal_attributes(array(’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 <span> for adding title and class attributes
if (empty($link['html'])) {
$link['title'] = check_plain($link['title']);
}
$span_attributes = ”;
if (isset($link['attributes'])) {
$span_attributes = drupal_attributes($link['attributes']);
}
$output .= ‘<span’. $span_attributes .’>’. $link['title'] .’</span>’;
}

$i++;
$output .= “</li>\n”;
}

$output .= ‘</ul>’;
}

return $output;
}

Jscalender module come with Jstools package in drupal 5 you can download drupal jstools package from the drupal.org site.Jscalender uses the jsCalendar javascript library, like using a special CSS class called via #attribute in the form element array to convert textfields into jcalendar enabled.

The jcalendar module uses hook_form_alter() to look for textfields with the add-jcalendar class, I had to use something different than jcalendar which is used later on the generated form elements by the jQuery code.

This is a sample of how to enable jcalendar from one of your textfields once you’ve installed the module:

To include a jscalendar popup with a textfield, just add the class ‘jscalendar’:(from readme.txt)

$form['date'] = array(
‘#type’ => ‘textfield’,
‘#attributes’ => array(’class’ => ‘jscalendar’),
);

To change the default display and functionality of the calendar, set startup
parameters by adding selectors to your element. The three configurable options
are ‘ifFormat’ (the format of the date/time written to the text field),
’showsTime’ (boolean: should time be displayed on the calendar), and
‘timeFormat’ (values of ‘12′ for 12-hour clock, which is the default, or ‘24′
for 24-hour clock).

Example:
$form['date'] = array(
‘#type’ => ‘textfield’,
‘#attributes’ => array(’class’ => ‘jscalendar’),
// Use only year, month, and day in textfield.
‘#jscalendar_ifFormat’ => ‘%Y-%m-%d’,
// Don’t show time.
‘#jscalendar_showsTime’ => ‘false’,
// Show 24-hour clock.
‘#jscalendar_timeFormat’ => ‘24′,
);

$form['firstdate'] = array(
‘#type’ => ‘textfield’,
‘#title’ => ‘The first date’,
‘#default_value’ => ‘2007-09-29′,
‘#weight’ => -20,
‘#attributes’ => array(’class’ => ‘add-jscalendar’),
‘#description’ => t(’YYYY-MM-DD’),
);

The #jcalendar_year_range custom property allows you to provide a range of years, look at the associative array $years, to show in the calendar. If the property is not passed jcalendar.module defaults to the current year plus 20.

#jcalendar_plot_dates, which is not working yet, should allow passing an array of dates to the calendar to plot. I’m not sure if this should be the job of the Drupal module or jCalendar’s jQuery code.

This first version of jcalendar.module works, it converts your textfield to three select boxes, day, month, year, and a nice table based date picker, easy to theme via CSS, and once you have the right date you can do whatever you want with it. The original textfield is removed later so your form validation and processing functions should consider if jcalendar is enabled (a simple if (module_exists(’jcalendar’))) to handle form elements in a different way.

Many times it is needed to get the structure of table in PHP file or drupal module.There may be conditions that you dont have got admin user name and passwords for cpanel/phpmyadmin.In such cases you must have idea how to know the structure using a small PHP code.you can get connection info for mysql from code files or if you are using ftp it is sure that u can run a SQl query from code file.So below is the simple script for getting table info

Simple PHP Mysql


$table_name="node";
$sql=sprintf("SHOW COLUMNS FROM %s",$table_name);
$$rs=mysql_query($sql);
while($col=mysql_fetch_object($rs))
{
print_r($col);
}


Drupal And Mysql

$table_name="node";
$sql=sprintf("SHOW COLUMNS FROM %s",$table_name);
$$rs=db_query($sql);
while($col=db_fetch_object($rs))
{
print_r($col);
}

Once you have checked structure you must be able now to add alter structure of table using same code method:-

mysql_query("ALTER TABLE user_info ADD user_coupon varchar2(50)");
