CakePHP Forms, where to find and how to modify? - forms

I'm currently new to cakephp and I just want to ask how can I accomplish this,
a select box in which I'm the one determining its options,
<?php echo $this->Form->input('treat', array('class' => 'form-control')); ?>
or how can I trace the code above to know where in the MVC did he determine his options for his selectbox. tnx

#SOS as suggested by #ndm read up on the Form Helper.
There are generally two ways to pass the options to a select via the Form Helper.
First if you have baked the application the contents of the select could be in the DB.
The Form Helper recognizes Model associations and builds the forms accordingly.Thus the contents of the select should be in the DB. For example if you have User belongsTo/hasOne UserType, the userTypes select will be populated from the DB table for userTypes.
The other way is as was already said, but unclear:
one can directly pass the options parameter of the Form->input() function.
There is another function that creates selects via the FormHelper: select().
Check it here

You can use the below code to define the options -
<?php echo $this->Form->input('treat', array(
'class' => 'form-control',
'type' => 'select',
'options' => array(
'1' => 'option 1',
'2' => 'option 2'
)
)); ?>
Just specify the options in the options array. you can also specify the blank option in that by writing 'empty'=>'Please Select' in the array list.

cakePHP: form with related models not automagic updating

I struggle with getting a form to work in the way I want it to behave.
I have a Regions and Properties model, one region can have many properties and so on...
I created a form to select the Region and then a Property in that region!
The form is having both lists but I struggle to have the second list [Property] updating automagic with only the properties in the region you have selected from the first list [Regions]
When you select a different region in the list, it should update automagic the property list, so you only see the properties for that region! Sorry for my bad explaining, but not sure how to explain this any better.
This is the code in my controller:
// Retrieve the region list
$this->set('regions', $this->Region->find('list', array(
'fields' => array('Region.id', 'Region.regionname'),
'order' => 'regionname',
)));
// Retrieve Property list for the regions.
$this->set('properties', $this->Region->Property->find('list', array(
'conditions' => array('Property.live' => true ),
'fields' => array('Property.id','Property.description'),
'order' => 'id',
)));
This is part of my form.
<?php echo $this->Form->create('Upload', array('action' => 'add', 'type' => 'file')); ?>
<?php echo $this->Form->input('region_id', array('label' => 'Select Region:')); ?>
<?php echo $this->Form->input('property_id', array('label' => 'Select Property:')); ?>
<?php echo $this->Form->file('file'); ?>
I have spend a lot of time looking around here and on youtube, but can't find it :-(
There's no automagic way to do what you're asking. Since all the data for dropdowns have already beed displayed on load, the only way to change the second dropdown depending on the first select is via javascript.
If you search for "dropdown on select" or something similar for cake, you'll find solutions to do it with ajax or plain js. I leave you one reference here. That one is done with ajax and a new action. But you could also do it with just js, doing a find for Regions and Properties and setting them in a json variable in js to be manipulated.

how to load data from database to my own custom field type (form)

I would like to create a custom form field. For example, select field of cities in the world.
I read this article. In this article, the data are loaded using parameter file config.ynl. I, however, I'd like to upload this data from my database.
http://symfony.com/doc/current/cookbook/form/create_custom_field_type.html
Can somebody tell me how to do this or send the link to the example
In this case, better is to use an Entity Field instead of a Choice Field. It allows you to request your database to load your entities as follow,
$builder->add('MyField', 'entity', array(
'class' => 'MyBundle:MyEntity',
'query_builder' => function(EntityRepository $er) {
return $er->createQueryBuilder('e');
},
'property' => 'something',
));
The property option define the entity property you want to use.
You can then customize your field using the "multiple" and "exanded" options to behave the way you want. Read the documentation

Add a dropdown list as custom field in magento

I added custom fields as described in magento add custom input field to customer account form in admin
But I want a select list, not only a text input one. I don't know which kind of parameter I have to set and how to tell the list of possible values.
Please help :)
Thanks,
Plantex
Where you might do something like:
$setup->addAttribute('customer', 'custom_attribute', array(
'type' => 'text',
'label' => 'Customer Custom Attribute',
));
Use these values instead:
$setup->addAttribute('customer', 'custom_attribute', array(
'type' => 'int',
'label' => 'Customer Custom Attribute',
'input' => 'select',
'source' => 'eav/entity_attribute_source_boolean',
));
The type is int because you will typically be storing the index of the value chosen, not the value itself. The input is select so the admin renderer knows which control to use. The source shown here is a common example, it provides an array of "Yes" and "No" values with numeric indexes.
There are many source models already in the Magento code that you can use and you can create your own too, look at any existing one to see how it returns an array. If you make your own and if it uses text indexes instead of numeric then the type will have to be changed back to text.
Try adding this at your module setup file
'value' => array('notate_to_zero'=>array(0=>'Bleu',0=>'Rouge',0=>'Vert',0=>'Violet',0=>'Noir',0=>'Orange'))
),
or look at this --> http://inchoo.net/ecommerce/magento/how-to-create-custom-attribute-source-type/

CakePHP Form in an Element Causing Errors

I think this may be an easy solution, but I've spent an hour now investigating to no avail.
I have a registration form in an element that is being used in views belonging to different controllers. Using the "url" attribute, I've told it to submit to /users/register, but for some reason, the fields aren't submitting to the database.
Instead, there are errors for "undefined index" and a MySQL error for an undefined secondary key that I set (it's empty because it's not being submitted). Strangely, the form works fine if I include the element somewhere in the users views. Does anyone know why this is happening?
UPDATE - Here's the relevant code, sorry:
<?php
echo $form->create(array(
'id' => 'signupform',
'url' => array(
'controller' => 'users',
'action' => 'register')));
?>
The form fields are all correct, since the element works in the user controller's views anywhere. Do I need to include any other information in the creation of the form to point it more directly?
Specify the model 'User' as the first parameter to the $form->create() method.
<?php
echo $form->create('User', array(
'id' => 'signupform',
'url' => array(
'controller' => 'users',
'action' => 'register')
)
);
?>
This will ensure that the form fields are named as data[User][field_name], and prevent you from seeing that undefined index error.
Hope this works for you!
Without seeing the code, it sounds like Cake is magically assuming that the Model is the one for the controller that controls the current view. When that controller is Users, it works correctly. When it is, say, Articles, it will be trying (and failing) to fit the form fields to the Article model.
Without seeing any code, it is impossible to offer any more help.
EDIT:
If the form contains mixed models, e.g. User and Article, you must prefix the fieldnames like this:
$form->input('User.username');
$form->input('Article.title');
etc.
If you don't, the controller will assume they all belong to its own model.

Zend_Navigation overwrite with array?

I currently use zend_navigation via an XML file.
However I need to overwrite the previous breadcrumb to be its dynamic parent, in the controller.
Is this possible? It seems to me that zend_navigation is fairly static and the zend documentation keeps timing out.
Thanks
I have put:
public function addAction() {
$this->view->navigation()->addPage(array(
'type' => 'uri',
'label' => 'New page')
);
in my controller but no crumbbar shows up for that page.
Any ideas? $this->navigation() threw a
Method "navigation" does not exist and was not trapped in __call()
Also of note that my crumbBar is in my layout and not individual views.
Yes you can use an array.
What you should do really is create your array and then input it into the factory of the Zend_Navigation to create your pages for you.
Unfortunately my code is too complicated to show an example of how I used it. But I'll provide a simple example...
Once you create your navigation container, you can just add new pages to it.
Like
$this->navigation()->addPage(array(
'type' => 'uri',
'label' => 'New page'));
But you can also use addPages(). This is what I do.
I think you should just wait for the documentation to load back up for you and then look at that. Its really easy in fact.
When you have a more specific question, just ask that and give me a poke. I've had to use Navigation quite a lot so know it quite well.
Additionally, check out #zftalk on freenode. Theres lots of help on there.
// Disable Layout
$this->view->layout()->disableLayout();
$this->_helper->viewRenderer->setNoRender(true);
// Output XML than HTML
$this->getResponse()->setHeader('Content-Type', 'text/xml; charset=utf-8');
$container = new Zend_Navigation();
// Replace this section with real dynamic data.
$pages = array(
array(
'label' => 'Save',
'action' => 'save',
),
array(
'label' => 'Delete',
'action' => 'delete',
),
);
// Add pages
$container->addPages($pages);
$this->view->navigation($container);
// Output the data.
echo $this->view->navigation()->sitemap();
Additionally uses Zend Router for redirecting site.com/sitemap.xml to this controller/function.
Thank you for many developers who help me to reach here.
