//Delete the orginal file
if($src==$dest)
@unlink($src.DS.$name);
return $dest_filename;

All the internal or external menus are stored in the table “menu_router”.

/*
* Find the path is available
* Parameter menu path
* return TRUE if menu exists else return FALSE
*/

function is_path_exists($path) {
return (db_fetch_array(db_query("SELECT * FROM {menu_router} where path = '%s' ", $path))) ? TRUE : FALSE;
}


The above three categories are covers your all drupal pages. So the following code will used to get template suggestion as per node or menu or argument.


/**
* Override or insert PHPTemplate variables into the templates.
*/
function phptemplate_preprocess_page(&$vars) {
// first, proceed with a modifed version of the standard
// Drupal template suggestion calls
$i = 0;
$suggestions = array();
$suggestion = 'page';
while ($arg = arg($i++)) {
$suggestions[] = $suggestion .'-'. $arg;
if (!is_numeric($arg)) {
$suggestion .= '-'. $arg;
}
}
if (drupal_is_front_page()) {
$suggestions[] = 'page-front';
}
// next, check for templates that use the path alias
if (module_exists('path')) {
$alias = drupal_get_path_alias(str_replace('/edit','',$_GET['q']));
if ($alias != $_GET['q']) {
$template_filename = 'page';
foreach (explode('/', $alias) as $path_part) {
$template_filename = $template_filename . '-' . $path_part;
$suggestions[] = $template_filename;
}
}
$vars['template_files'] = $suggestions;
} // end path alias template check
if ($suggestions) {
$vars['template_files'] = $suggestions;
}

if (isset($vars['node'])) {
// When viewing a node focused as a full "page", it will suggest the node type.
// For example, a node type of "some_foo" will search for "page-some-foo.tpl.php".
$vars['template_files'][] = 'page-'. str_replace('_', '-', $vars['node']->type);
}
}


The phptemplate_page_preprocess used to override drupal variables. The template file have been override the above code.

The same way you can user node template also.

Example:

$menu = menu_get_item('admin/store/export');
$content = system_admin_menu_block($menu);
$output = theme('admin_block_content', $content);

The above code get all the sub-menus under export parent menu.

Question 1: How to validate XHTML?

Answer: Before going to answer this question, i need to explain some of basic things in XHTML. I used Dreamweaver in windows, Aptana in Mac, Komodo in Linux. Those editors make default in document type, header and body tags. some of guys never take care about the document type because of the editors will handle. It is important one. Make sure what are the editors you are used and what are the default code placed when you create new html file. I hope every one should know about what is XHTML. Let see about How to validate XHTML.

The XHTML have Three doctype.
1. strict
2. transitional

Using above three doctype you can validate XHTML. For more information see How to validate XHTML

Drupal is the best CMS with building media related sites. Galleria is the best module for image gallery in drupal, the galleria module did not support caption when you use image filefield because the gallery module get caption for field description. When you use filefield it is support title and alt input field.

So here is the solution for getting caption for image in title tag.

1) In the content type manage fields enable alt and title tags.
2) Add the following coding in your galleria.module file function theme_galleria_formatter_imagefield_galleria end the “alt” text.
‘title’ => $element[$key]['#item']['data']['title']
3) Replace the coding in the function “template_preprocess_galleria”
$caption = ($image->title != $image->filename) ? $image->description : ”;
to
$caption = ($image->title != $image->filename) ? $image->title : ”;

Now view your galleria image gallery, caption will dispaly.

Cheers!

Add the below code in your template.php them file.

function phptemplate_preprocess_page(&$variables) {
$breadcrumb = drupal_set_breadcrumb();
if($breadcrumb[1]==”"){
$breadcrumb[1] = $variables["title"];
$variables['breadcrumb'] = theme(‘breadcrumb’, $breadcrumb);
}
}

Example i have open the page in windows machine the windows video is shown. if i open the page in mac system the mac video is shown.

Function refference:

1) getos – this function used to get client machine environment

2) replacevideo – this function used to return the bulk of video object

How to use this code?

1) Open in your wordpress/wp-content/themes/youthemes/functions.php file and add the below code.

2) Edit your post / create your post and add the line ‘[getvideo 1]‘.

Code:

/*

* and replace the video file
*/
function add_video_content($content = ”) {
$platform = getos();
$winmsg = ‘<strong>Windows videos</strong><br>’;
$macmsg = ‘<strong>Mac videos</strong><br>’;
if(trim($platform)==”mac”)
$content = str_replace(‘[getvideo 1]‘, $macmsg . replacevideo(‘mac/macvideo.flv’), $content);
else
$content = str_replace(‘[getvideo 1]‘, $winmsg . replacevideo(‘windows.flv’), $content);
echo $content;
}

//add filter the_content
add_filter( “the_content”, “add_video_content” );

//replaced video object
function replacevideo($vidfile){
$st = ‘<object width=”500″ height=”402″ data=”http://dragonfablepowerlevel.com/members/flowplayer/flowplayer-3.1.5.swf” type=”application/x-shockwave-flash”>’;
$st .= ‘<!–> <![endif]–>’;
$st .= ‘<!–[if IE]>’;
$st .= ‘<object type=”application/x-shockwave-flash” width=”500″ height=”402″‘;
$st .= ‘classid=”clsid:D27CDB6E-AE6D-11cf-96B8-444553540000″‘;
$st .= ‘codebase=”http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0″>’;
$st .= ‘<![endif]–>’;
$st .= ‘<param value=”http://yourdomain/flowplayer/flowplayer-3.1.5.swf” name=”movie”/>’;

$st .= ‘<param value=”transparent” name=”wmode”/>’;
$st .= ‘<param value=”sameDomain” name=”allowScriptAccess”/>’;
$st .= ‘<param value=”high” name=”quality”/>’;
$st .= ‘<param value=”config={\’playerId\’:\’player\’,\’clip\’:{\’url\’:\’http://yourdomain/’ . $vidfile .’\'},\’playlist\’:[{\'url\':\'http://yourdomain/' . $vidfile .'\',\'autoPlay\':false, \'loop\':true}]}” name=”flashvars”/><p>Your browser is not able to display this multimedia content.</p>’;
$st .= ‘</object>’;
return $st;
}

// Get client platform
function getos(){
$userAgent = strtolower($_SERVER['HTTP_USER_AGENT']);
if (preg_match(‘/linux/’, $userAgent)) {
$platform = ‘linux’;
}
elseif (preg_match(‘/macintosh|mac os x/’, $userAgent)) {
