What I am looking for is a page_id/view_id that I can use to identify and style specific pages. I would use the title or the url, but there is a chance that it could change if the a higher-up decides that the page should no longer be called Golf, but rather Tee-Time because he likes it better.
Presumably this identifier would not change if the current page were to be a paged view (page 1,2,3,4...).
One way of solving this is the following. It's depending on the url, so if it changes, so does the class-name.
In my themes template.php I implemented hook_preprocess_page:
function mytheme_preprocess_page(&$vars, $hook) {
$body_classes = array();
$body_classes[] = 'page-' . _get_page_name($_SERVER['REQUEST_URI']);
$vars['body_classes'] = implode(' ', $body_classes);
}
function _get_page_name($request_uri) {
static $numeric_subsection = array(
'/node/' => 'node',
);
$preAlias = $request_uri;
$alias = substr(strrchr($preAlias, "/"), 1);
if (strpos($alias, '?') > -1) {
$alias = substr($alias, 0, strpos($alias, '?'));
}
$page_name = $alias;
if (empty($alias)) {
$page_name = 'start';
}
else if (is_numeric($alias)) {
foreach ($numeric_subsection as $section => $pn) {
if (strpos($preAlias, $section) > -1) {
$page_name = $pn;
}
}
}
return $page_name;
}
Then in the main page-template:
<body class="<?php print $body_classes; ?>">
This isn't a generic solution. So you'll probably have to customize this for your specific needs. It will for example need som tweaking to play nicely with path auto.
This depends a little on how your site is put together (panel pages, view pages, "normal" pages). Essentially, you need to figure out what vars are in scope, and then determine which information in them can be used. To determine what is in scope, you can use print_r(array_keys(get_defined_vars())); and then poke around in the individual vars.
An option is to do something in theme_preprocess_page. One option is to get the page data via page_manager_get_current_page(), poke around in there, and then add body classes as needed. Without knowing what you are doing, you essentially need to print_r the results somewhere, look at what you have, and go from there.

I use if else for custom menus in Wordpress, to load various location menus based on parent page. The agency I work for is adding countless amounts of cities, and it's getting out of hand. One thing I am trying to do, is come up with a more efficient way to check the items, someone suggested switch, and I just wanted to throw this out there and see what you all think. These are not complete codes, and I know the menus are bad UX, and all that, it's not my call. I just want some input on performance differences. thanks.
Here is an example of switch code:
function is_subpage() {
global $post; // load details about this page
if ( is_page() && $post->post_parent ) { // test to see if the page has a parent
return $post->post_parent; // return the ID of the parent post
} else { // there is no parent so ...
return false; // ... the answer to the question is false
}
}
$selectedMenu = "primary";
$my_page_id = is_subpage();
if(!$my_page_id)
$my_page_id = get_the_ID();
switch ($my_page_id) {
case('489'):
$selectedMenu = 'columbus';
break;
case('6583'):
$selectedMenu = 'cumming';
break;
}
wp_nav_menu( array(
'theme_location' => 'main-menu',
'menu' => $selectedMenu,
'menu_class' => 'clearfix'
));
and here is an example of if else code:
if(is_page( '28' ) || '28' == $post->post_parent) { $locationMenu = 'louisville'; }
'menu' => $locationMenu,
Don't second guess or assume anything about the efficiency of an interpreter or compiler. if else might be better at one scenario and switch at another.
The problem with your code is readability and maintainability and not performance. It is hard to be specific without knowing all details about your needs, but it seems like what you need is to have at each post a custom field which indicates the menu associated with that post, and then the admin can configure them and you will have some more coffee time ;)
This is actually a worse solution in terms of performance, but if you really need the site to be fast then you are going to use a caching plugin which will make the whole php related performance discussion just a waste of time.
From a PHP perspective...
In lieu of having the page id to location table in a database, you could include a structure like this on pages you need it:
$idToLocation = array(
"489" => "columbus",
"6583" => "cumming"
// et cetera
);
Then to get the location:
$id = "489"; // for example
if (!array_key_exists($id, $idToLocation)) {
echo "location for id not found";
die();
}
$location = $idToLocation[$id];
Hi I am using ItextSharp For searching Cross References(Internal Links) In pdf file. I already done with External Links.
Please Post If u have any solutions.
//Get the current page
PdfDictionary PageDictionary = R.GetPageN(page);
//Get all of the annotations for the current page
PdfArray Annots = PageDictionary.GetAsArray(PdfName.ANNOTS);
//Make sure we have something
if ((Annots == null) || (Annots.Length == 0))
// return null;
{
Console.WriteLine("nothing");
}
//Loop through each annotation
if (Annots != null)
{
foreach (PdfObject A in Annots.ArrayList)
{
//Convert the itext-specific object as a generic PDF object
PdfDictionary AnnotationDictionary = (PdfDictionary)PdfReader.GetPdfObject(A);
//Make sure this annotation has a link
if (!AnnotationDictionary.Get(PdfName.SUBTYPE).Equals(PdfName.LINK))
continue;
//Make sure this annotation has an ACTION
if (AnnotationDictionary.Get(PdfName.A) == null)
continue;
//Get the ACTION for the current annotation
PdfDictionary AnnotationAction = AnnotationDictionary.GetAsDict(PdfName.A);
// PdfDictionary AnnotationAction = (PdfDictionary)AnnotationDictionary.Get(PdfName.A);
//Test if it is a URI action (There are tons of other types of actions, some of which might mimic URI, such as JavaScript, but those need to be handled seperately)
if (AnnotationAction.Get(PdfName.S).Equals(PdfName.URI))
{
PdfString Destination = AnnotationAction.GetAsString(PdfName.URI);
string url1 = Destination.ToString();
}
}
}
You've already done most of the work. Please take a look at the following screen shot:
You see the /Annots array of a page. You are already parsing that array in your code and you skip all annotations that aren't of the /Subtype /Link or don't have an /A key, which is excellent.
Currently you're only looking for values of /S that are of type /URI. You say you're already done with external links, but that's not true: you should also lok for entries where /S is /GoToR (remote goto). If you want internal links, you need to look for /S values equal to /GoTo, /GoToE, and (in the future) /GoToDp. Maybe you also want to remove the /JavaScript actions, because they can also be used to jump to a specific page.

I am struggling with the paginator in Cakephp 2.0. While I am trying to migrate my application to 2.0 I cant find any solution to jump directly to the last page. In 1.3 it was quiet to do that from outside like this:
echo $this->Html->link(__('Flights'), array('controller' => 'flights',
'action' => 'index','page' => 'last'));
but this little trick putting 'page:last' in does not work anymore in 2.0. Of course there is a Paginator function called last, but this would only help if I would be already inside the app. My Problem is to access from an outside link directly the last page of the paginator.
This is the simple way:
echo $this->Paginator->last('Any text');
Other way to get the number of the last page is:
echo $this->Paginator->counter(array('format' => '{:pages}'));
Then you can use it to generate your link.
For more info:
http://book.cakephp.org/2.0/en/core-libraries/helpers/paginator.html#PaginatorHelper::last
Shortly after creating a bounty for this question I found the solution to MY problem using CakePHP 2.2.4. I was trying to accomplish the same task but instead using version 2.2.4 instead instead of 2.0. Basically if I had a link that looked like http://www.domain.com/articles/page:last that the controller's pagination method would know what page to go to and display the correct results (articles) for that page. For example, if I have 110 articles and the pagination limit is set to 25, by going to that URL it would display page 5 of 5, showing records 101-110. I also wanted the same capability if I go to “page:first”.
I needed to change my library file lib/Cake/Controller/Component/PaginatorComponent.php.
I changed
if (intval($page) < 1) {
$page = 1;
}
To
if ((intval($page) < 1 && $page != "last") || $page == "first") {
$page = 1;
}
I also added
if($page == "last"){
$page = $pageCount;
}
After the line
$pageCount = intval(ceil($count / $limit));
Christian Waschke, with this solution, you can use the same link helper exactly how you wrote it in your question. For me, the link helper looked like this
<?php echo $this->Html->link('Go to Last Page', array('controller' => 'articles', 'action' => 'index', 'page' => 'last')); ?>
You can 'calculate' the last page yourself if 'last' is passed as the page number;
I would discourage making modifications in the CakePHP library files as this will make it hard to perform upgrades in the future.
Basically, the PaginatorHelper uses viewVars that are calculated and set by the PaginatorComponent, as seen here: https://github.com/cakephp/cakephp/blob/master/lib/Cake/Controller/Component/PaginatorComponent.php#L212
You can replicate this in your action; for example:
public function index()
{
if (!empty($this->request->params['named']['page'])) {
switch($this->request->params['named']['page']) {
case 'first':
// replace the 'last' with actual number of the first page
$this->request->params['named']['page'] = 1;
break;
case 'last':
// calculate the last page
$limit = 10; // your limit here
$count = $this->Flight->find('count');
$pageCount = intval(ceil($count / $limit));
// replace the 'last' with actual number of the last page
$this->request->params['named']['page'] = $pageCount;
break;
}
}
// then, paginate as usual
$this->set('data', $this->paginate('Flight'));
}
To improve this, this logic should be moved to a separate method, or to a behavior. However; as seen above, it is not required to make modifications in the PaginatorComponent!
Also note that the 'find(count)' in my example does not take additional conditions, they should be added if required
If you have a look in the CakePHP 1.3 source for paginate(), the code above is comparable; https://github.com/cakephp/cakephp/blob/1.3/cake/libs/controller/controller.php#L1204
How do you deal with the fact, that URLs are case sensitive in xPages even for parameters? For example URL:
my_page.xsp?folderid=785478 ... is not the same as ...
my_page.xsp?FOLDERID=785478
How to make, for example, a proper check that params contain some key e.g.
param.containsKey("folderid") which desnt work when there is 'FOLDERID' in URL.
I'd suggest defining a couple convenience #Functions:
var #HasParam = function(parameter) {
var result:boolean = false;
for (var eachParam : param.keySet()) {
if (eachParam.toLowerCase() == parameter.toLowerCase()) {
result = true;
break;
}
}
return result;
};
var #GetParam = function(parameter) {
var result = "";
if (#HasParam(parameter)) {
for (var eachParam : param.keySet()) {
if (eachParam.toLowerCase() == parameter.toLowerCase()) {
result = param.get(eachParam);
break;
}
}
}
return result;
};
Then you can safely query the parameters without caring about case. For bonus points, you could add requestScope caching so that you can skip looping through the keySet if you're examining a parameter that you've previously looked at during the same request.
you may use this function:
context.getUrlParameter('param_name')
then test if it's null or not.
make sure to decide for one,so either upper or lowercase
other than that i'd suggest something like
KeyValuePair<string,string> kvp = null;
foreach(KeyValuePair<string,string> p in param)
{
if(UPPERCASE(p.Key) == UPPERCASE("folderid"))
{
kvp = p;
break;
}
}
syntax isn't correct and idk the uppercase method in c# right now,but you get the point
The easiest answer is ofcourse the obvious. Be sure that the parameters you are using througout your application are always the same on every url you are generating and know what to expect. A good approach to accomplish this is to create a ssjs function which generates url's for you according to the objects you submit.
In this function you could check which object you are receiving and with the use of keywords and so forth generate the correct url. This way generating twice a url with the same input parameters should always generate the exact same url.
another option would be just to double check with a bit of code like this
var key = "yourkey";
if(param.contains(#uppercase(key)) || param.contains(#lowercase(key)){
// do stuff
}
But should not be necesarry if the url you are parsing is generated by your own application
Edit after post of topic starter
Another option would be to grap the url directly from from the facescontext and to convert it to a string first. When it is a string you can parse the parameters yourself.
You can combine server side substitution/redirection to get around the issue that David mentioned. So a substitution rule will redirect incoming patern like this:
http://myhost/mypage/param (/mypage/* => which converts to - /dbpath/mypage.xsp?*) - substitution is tricky so please handle with care.
Also I believe I read somewhere that context.getUrlParameter is not case sensitive - can someone please confirm this.
Hope this helps.
This should be a very simple question, but I'm finding it surprisingly hard to find an answer.
I'm creating custom pages using hook_menu that have both static content and dynamic aspects, (mainly from sql queries and views embeds etc...). My question is, how does drupal's cache system treat these custom pages?
I'm concerned because as the traffic ramps up on some occasions, I feel like I need some kind of caching control over the display of these pages, but at this point, I have no idea if they're automatically being cached, or if I need to somehow specify to drupal that I do indeed want them cached.
Just to clarify, these pages are not admin pages, but are accessible by anyone.
The result of a menu callback is cached only when the menu callback returns the output; when the menu callback prints the output, it's not cached.
The code execute to bootstrap Drupal when a page is requested is the following:
require_once './includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);
$return = menu_execute_active_handler();
// Menu status constants are integers; page content is a string.
if (is_int($return)) {
switch ($return) {
case MENU_NOT_FOUND:
drupal_not_found();
break;
case MENU_ACCESS_DENIED:
drupal_access_denied();
break;
case MENU_SITE_OFFLINE:
drupal_site_offline();
break;
}
}
elseif (isset($return)) {
// Print any value (including an empty string) except NULL or undefined:
print theme('page', $return);
}
drupal_page_footer();
drupal_page_footer() is the function that caches the result.
function drupal_page_footer() {
if (variable_get('cache', CACHE_DISABLED) != CACHE_DISABLED) {
page_set_cache();
}
module_invoke_all('exit');
}
page_set_cache() is the function that does the real work.
function page_set_cache() {
global $user, $base_root;
if (!$user->uid && $_SERVER['REQUEST_METHOD'] == 'GET' && page_get_cache(TRUE)) {
// This will fail in some cases, see page_get_cache() for the explanation.
if ($data = ob_get_contents()) {
if (variable_get('page_compression', TRUE) && extension_loaded('zlib')) {
$data = gzencode($data, 9, FORCE_GZIP);
}
ob_end_flush();
cache_set($base_root . request_uri(), $data, 'cache_page', CACHE_TEMPORARY, drupal_get_headers());
}
}
}
The content is compressed (if the zlib is enabled), and saved in the cache.
If you want the cache the output of a custom menu callback, then you just need to return the output, instead of printing it directly.
function mymodule_callback() {
// …
return $output;
}
Instead of caching the output of the page, you can cache the data the module used to build its output. If, in example, the output data is obtained with an SQL query, you can cache the result of the query.
