I am using Cake PHP with scaffolding. I'm having a problem with the code that it generates and want to see if there is a way around it of if I should end up building custom views.
Lets say that I have two models Tests and Questions. Tests can have many Questions and a Question has only one test. I have setup the hasMany and belongsTo Associations.
Now, the scaffolded view that cake creates for Tests gives me a button at the bottom in the "Related Questions" to create a question. When I click this button, I get the 'Add' form for questions, but the right test is not auto selected.
Is there anyway I can make the button pass the test_id into the Question form and have that auto populate?
I see how you think that might work; but Cake doesn't know you want that behaviour out of the box.
You would need to adjust your Question Add method, or create a new one:
Example code:
// action: tests/view/1 (viewing test 1, and all related questions)
// create a link containing the ID of the current test as a param
<?php echo $this->Html->link('Add Question to Test',
array('controller'=>'questions',
'action' => 'add_question',
$test['Test']['id'])
);
?>
So - assuming you have access to id of the current test, you can pass it as a parameter to your questions controller (there are several ways to do this).
Then:
// view - questions/add_question/1
<h1>Adding A Question to Test 1</h1>
<?php
// create your add question form
$this->Form->input('test_id', array('type'=>'hidden',
'value' => $this->params['pass'][0]));
// create a hidden field with the value of the first passed param (the test id)
then in your controller, the test_id is already set, so when you save the question, it is saved with the appropriate test_id
If you want to apply this to all your CakePHP projects generated using cake bake, you can make a couple of small changes to the CakePHP core to enable this, as seen here:
https://github.com/srs81/cakephp/commit/7d92c8f676c79185fa6a74ab2070f240c555a2a0
Basically these two changes append the referring model/controller ID and name to the "add" action, and this is handled in the "add" action where the correct ID is selected.
This does NOT work for HABTM models, but should work fine for anything else.
You need to add var $uses = array('Question','Test'); to questions_controller.php

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've been trying for the past 2 days, how to embed a view from a different controller.
I have two tables (hotels, hotelQuotes), related to each other. The hotels table is linked with a hasmany to the hotelQuotes table, and hotelQuotes with a belongsTo hotels table. Both are linked and working, they both show their related content with no problem.
The hotelQuotes it's pretty much a form, where users fill it out, and then it sends an Email with what the user filled out. Everything is working fine up to this point.
What I want is, when I show the information about the hotel, is to also show that form, I dont want the user to go to another page to fill out the form. So I pretty much want to embed the view of hotelQuotes/Add to the hotel/view.
I doing that using elements, as recommended last night in #cakephp IRC channel, and also here in StackOverFlow at: Embedding view in another view with CakePHP
The problem is that when I do that, the association between the two models gets broken. I mean, the users fill out the form, but I have nowhere to know where that form is coming from, what hotel is referring to. It just doesn't show that piece of vital information for me.
I've been reading about passing variables when using elements at: http://book.cakephp.org/2.0/en/views.html#passing-variables-into-an-element but I don't know how to pass a variable to a form select box. I am using CakePHP 2.5.2.
I hope I explain myself clear here, any input it would be appreciated. See picture below for more info:
http://i.stack.imgur.com/wcG64.jpg
Edit> I just realized that the form is not even submitting when I using elements. Why would that be?
Ok, I just figured out.
The form wasn't even submitting when calling it from elements. So I just passed the action myself like so:
echo $this->Form->create('Hotelquote', array(
'action' => 'add'
));
And now is working.
I create by $this->Form->input('field') automatic populate multiple select box.
But how to use code above to select options in edit action which saved values?
make sure your form is created with the correct model
eg `$this->Form->create('Article');
pass a variable as the singular of your model from the Controller via $this->set(). For example, if your model is "Article", then pass a variable with the data:
$this->set('article', $article);
it will populate automatically
Next time you ask a question on StackOverflow, provide information on what you've tried, what worked, what didn't, what you've search for but couldn't find...etc, so it doesn't feel as though we're just writing code for you.
Update (per additional info in comments):
For HABTM, create your field with the model:
$this->Form->input('PartnerState');
Then pass a variable camelCase plural:
$this->set('partnerStates', $partnerStates);
The short version of this question is:
How can I take data that only exists in an array (ie: not saved in a model yet) and relate it to a value in a $this->find('list') array from a model?
The long version of this question is:
I'm using CakePHP and the Wizard Component for a 3-step application form.
The 3 form steps are contact, course and details.
After these steps, there is a 'review' step which I want to display all of the submissions from the previous 3 form steps for the user to check one last time before pressing submit. For the most part, this works very well. I just need to do the following in the controller:
function _prepareReview() {
$contact = $this->Wizard->read('contact');
$course = $this->Wizard->read('course');
$details = $this->Wizard->read('details');
$this->set(compact('contact','course','details'));
}
Then, in review.ctp I can reference things like $contact['Contact']['firstname']; to get the person's firstname etc.
However, the problem is getting data from 'related' models. For example, there's a "Nationality" field which is just an ID. In the 'details' step, I use find('list') to get a list of all nationalities from the Nationality model as a dropdown menu which displays properly and then Cake saves the corresponding ID as it should do.
But, when I come to the 'review' step in the Wizard Component, I only get the actual ID from the Wizard Component's array. I couldn't really expect to get anything else.
I can't see any obvious way to access $details[Detail][Nationality][name] (or something like this) from the context of the Wizard Component because setting recursive doesn't work because the data isn't actually in the model at this stage, it's just an array of form data.
So, in other words, I have data in an array (NOT coming from a model, but from a form subsmission) as follows:
Array
(
[Details] => Array
(
[firstname] => Test
[nationality_id] => 3
)
)
Then I have the following coming from a $this->Detail->Nationality->find('list') which looks like this:
Array
(
[0] => American
[1] => Australian
[2] => British
[3] => Canadian
)
So how can I get $details['Details']['nationality_id']; from the Wizard Component to display 'Canadian' instead of '3' for example? How to I make the relationship when only one of the arrays is coming from a model? I only need this to momentarily confirm all of the data to the user. The id '3' will, of course, be written to the Model once the user presses submit, and this is already working as it should do.
Or is this a completely crazy way of doing things and I should look at a totally different approach such as saving the data first? I don't really want to save it until the user clicks the final submit, though.
I can see what you are getting at here - CakePHP isn't automatically querying these related models for you (as you aren't pulling from the database) but you can't help but think you are missing out on some of the framework's free functionality.
If you were still using FormHelper::input() it would automatically select the correct option (given you perform a Model::find('list') and passed the options list to the view first), but I'm assuming you wish for the review screen to be free of form inputs (disabled or not).
The most straightforward approach would be to simply perform the same Model::find('list') calls you do for each step in the wizard, set the data from each to the view, and print out the appropriate value manually:
// controller
$nationalities = $this->Review->Details->Nationality->find('list');
$this->set(compact(/*..., */ 'nationalities'));
// view
<?php echo $nationalities['Nationality'][$details['Detail']['nationality_id']]; ?>
outputs 'Canadian' (the value for $nationalities['Nationality'][3])
It might be possible to get CakePHP to do it for you by calling DboSource::queryAssociation() just right - if your up for the challenge - but is probably overkill for this particular problem.
// model
$db =& ConnectionManager::getDataSource($this->useDbConfig);
$data = $db->queryAssociation($model, $linkModel, $type, $association, $assocData, $queryData, $external, $resultSet, $recursive, $stack) {
I'm trying to create a menu in cake php where I can also know how many articles are inside the section, should I use a manual query, or does exist some existing method to do it?
My site menu:
- Works (12)
- Photos (35)
- Stuff (7)
- Contacts
My problem is also I didn't get how I can access to data like this for every view, this should be a main menu, so I should use this in every view but If i put it in default.ctp, every model deosn't exist, because I cannot access it from a view.
Does exist some page which talks about this?
Since those are separate models that are not related to each other, you'll need to do a manual count.
$this->Model->find('count');
EDIT
Ok, so looks like you are talking about different models.
If this is used in a menu, that means it will be shown in all pages.
You have two ways of doing this.
You can do it by having an AppController for you application. Basically, you can put this code in the beforeRender method so it runs everytime your a request is rendered
function beforeRender() {
App::import('Model', array('Work', 'Photo', 'Stuff'));
$work = new Work();
$workCount = $work->find('count');
//do the same for the other
$this->set('workCount', $workCount);
}
Have a look at this for more details on callbacks : http://book.cakephp.org/view/977/Controller-Methods#Callbacks-984
Secondly, you can do this via a helper. You can put the same code (that is inside the bforeRender) into a helper, and you can call the helper method.
You can look here for more info on creating a helper : http://book.cakephp.org/view/1097/Creating-Helpers
The CounterCache behavior will help you out:
