I have a searchable, sortable table in cakephp. The search and sort criteria are passed as named parameters. Now I would like to add a button which calls a method viewPdf on the very same controller to create a PDF showing the current table content. In fact, I get the correct PDF output just by replacing the action parameter in my url. But how do I get the correct link url for the button with all the current parameters?
I could implode all the values and keys of $this->params->named but I am sure there is a much better way to achieve what I want.
Regards

You are actually pretty close. You can form such a link using
$url = array('action' => 'pdf') + $this->request->params['named'];
echo $this->Html->link('Title', $url);
Assuming you are using cake2.x (which you always should mention in your question!).

How do I extract specific field for display in a taxonomy page?
I have a custom content type called "film" and each film has a Term Reference field called "casting". As expected I can click on a "casting" (tag) it brings me a page where all films are listed wherever this tag is associated. For expample if I click on "Kate Winslet" from movie Titanic, I land on a page http://localhost/mysite/tags/kate-winslet where other movies of Kate Winslet are listed. Up to this point everything is just fine.
I do not want Drupal to pull in and show default fields like just Title and Body in its own display format. Rather I want it so that I can display a photo from each film, year of release and of course the title and trimmed version of the body. I only want to customize the content of this page so that I have the control over What to Show and Where To Show a specific field value.
This is what I tried:
I cloned and put page.tpl.php in my theme's template folder. Renamed it as page--vocabulary--tags.tpl.php. Then I took out the following line of code (<?php print render($page['content']);?>) from my page--vocabulary--tags.tpl.php. The intention was to check whether the overridden template is actually being accessed by Drupal or not. It does!
But I am not been able to extract fields like field_photo or field_release_date from $page['content]. To get an idea about defined variables and how they are placed I used the following line of code:
<pre><?php /*print var_export(get_defined_vars(), TRUE);*/ ?></pre>. But even from there I could not extract a particular field like I mentioned above. The fields look to be somewhere inside $page['content']['system_main']['nodes'], but I don't know how to get to a specific field directly.
I also created a template.php with the following preprocess hook function:
<?php
function introduction_preprocess_page(&$vars) {
if (arg(0) == 'taxonomy' && arg(1) == 'term' && is_numeric(arg(2))) {
$term = taxonomy_term_load(arg(2));
$vars['theme_hook_suggestions'][] = 'page__vocabulary__' . $term->vocabulary_machine_name;
$vars['content'] = $vars['page']['content']['system_main']['nodes'];
}
}
?>
Both <?php print render($content) ?> and <?php print render($page['content']) ?> print the same result but I want something like <?php render($content['photo_field'])?> which I am not been able to.
I am sorry for making this too long. I have just stepped into Drupal. So wanted to make sure that what I am trying to explain matches exactly what I want to accomplish.
You are probably trying the long way to this.
You can use Views module. It allows to create custom listings querying the database, but also override existent ones, like the case of the taxonomy term page listing.
Once you have the module installed (if it's not yet), particularly the Views UI module, go to /admin/structure/views and scroll to bottom, where disabled views (grayed rows) are. You'll find one called Taxonomy term, described as 'A view to emulate Drupal core's handling of taxonomy/term.'
Click Enable on the right of it and then go to the same place where the Enable link is, click the arrow to unfold and choose Edit.
Once you're in the view edit page, you can manipulate the listing at your convenience, adding/removing fields or whatever you want to do in your particular case. If you are not familiar with Views, I recommend you to learn about it, there is a lot of related content on the web and it is close to essential for Drupal development.
Also, if you want to add more customisation to the page, you can use the same approach with the Panels module, who allows to override system pages (not just listings like Views).
I have been trying to create a component like the Bakery's Paginator Recall that would allow me to save pagination data for CakePHP 2.4 and run into the following issue.
All solutions involve saving the Paginator parameters in the session and then retrieving and applying them upon returning to that same page without specifying any.
This approach would have worked if only the Paginator helper functions like numbers(), first() and previous() would include the page:1 named parameter in the links that they generate for moving to the first page like the corresponding function of the 1.3 version.
Unfortunately all of these functions create URLs without the page parameter when they refer to the first page, so when users click on the first page link, the component does not find any paging info and hence it returns them to the previous position.
There must be some way to work around this, but for the moment I am completely stuck.
NOT including the page number in the link to the first page is by design.
Read the reason on the CakePHP 2.4 Migration guide.
I would suggest to use the same convention. When you do not have pagination information assume is page one, and do not add it to your URLs.
So all you have to do is code this special case when then pagination is missing. And in this special case your "recall" component will simply not add that page.
I believe that I have managed to create a working solution. Thanks to the advice I have received I have now created a working component like the original PaginationRecallCompoent.
I have written all the details in the following blog post.
I have a search form where User can enter data to be searched and after that he has the possibility to use pagination.
For pagination I have to send again and again the searched paramters. What will be the best way to handle this situation.
You can send that searched parameter through url as named parameter. For example:
http://127.0.0.1/cakeproj/controllers/action/q:searchedItem/...
and you'll get this named parameter in controller's action like:
$this->params->named;
or
$this->params['named'];
and it will give you an array like:
[named] => Array
(
[q] => 'searchedItem',
....
)
To get the searched item directly:
$this->params->named['q'];
or
$this->params['named']['q'];
I've got a Cake application with a reports query interface, where the admin user can filter the data by various inputs in a form and the results are then displayed on the screen. I am looking for the simplest way to add a button which allows the user to download the results of this same query as CSV.
I'm sure I can create one for myself if I have to, but is there already a way to regenerate any given form based on $this->data? That way, I can just add .csv to the form action and use RequestHandler to choose the right output format.
[here take a look at the following...
instead of finding the data from Db you can simply pass $this->data to it.
take a look at follo
Exporting data to CSV the CakePHP way
I guess you have to replicate the function on your controller, one for generating the results on screen and another same function intended for csv, but on the function for csv it must have parameters which are similar to the values of $this->data. Use javascript to redirect on the function for csv.
How can I filter Results by County,District,City with dropdown select.
Is there a way to do it in Cake way, because currently I'm doing it classic way, by passing Id to url, like:
/sort/county_id/1/district_id/5
But this is very bad hack, because I have to explode $this->here and not good thing. I don't know if there is uri class like in codeigniter, so I can play with $this->uri->segment().
In fact my problem is that I need to see if isset then pass it.
Have you considered named parameters?
