I've created a large form in Cake and set default options via inputDefaults. However I wish to change the default values for an individual field.
In setting the form defaults, I wrote approximately this:
'inputDefaults' => array(
'error' => array(
'attributes' => array(
'wrap' => 'span',
'class' => 'invalidate column-7 offset-3')));
...with the result that all like fields produce the same error message. But, when I attempt to change the defaults for a single field, like so:
echo $this->Form->input('name', array(
'error' => array(
'attributes' => array(
'wrap' => 'span',
'class' => 'invalidate column-10'))));
It doesn't work. The field name produces an error whose class reads column-7 and offset-3, whereas I'd intended column-10.
Anybody know a solution?
$options['inputDefaults'] You can declare a set of default options for input() with the inputDefaults key to customize your default input creation:
echo $this->Form->create('User', array(
'inputDefaults' => array(
'label' => false,
'div' => false
)
));
All inputs created from that point forward would inherit the options declared in inputDefaults. You can override the defaultOptions by declaring the option in the input() call:
echo $this->Form->input('password'); // No div, no label
// has a label element
echo $this->Form->input(
'username',
array('label' => 'Username')
);

I have Form input with multiple select options. I am unable to set default values. This is my code:
<?= $this->Form->input('PaymentMethods', array(
'type' => 'select',
'multiple' => true,
'label' => false,
'options' => array(
'cash'=>'cash',
'invoice'=>'invoice',
'ax'=>'ax',
'ca'=>'ca',
'vi'=>'vi',
'tp'=>'tp',
'dc'=>'dc'
),
'default'=>'ax'
)); ?>
How do I set default values for this input with PHP only?
This is working on my system. You can also set it from controller like this :
$this->request->data[$this->modelClass]['PaymentMethods'] = 'ax';

CakePHP select default value in SELECT input
http://book.cakephp.org/2.0/en/core-libraries/helpers/form.html
example :
$sizes = array('s' => 'Small', 'm' => 'Medium', 'l' => 'Large');
echo $this->Form->input(
'size',
array('options' => $sizes, 'default' => 'm')
);
Since this is multi-choice select, value given must be array. And the key shouldn't be default, I should've used value instead.
<?= $this->Form->input('PaymentMethods', array(
'type' => 'select',
'multiple' => true,
'label' => false,
'options' => $options,
'value'=> $array_of_data_fetched_from_database
)); ?>
Through cakephp how should able to handle quotes in option value.I have a:
$options => array(20"=>20",30"=>30",40"=>40")
Here i am using key and value are same. This array contains double quotes so html is display's:
<option value="20"">20"</option>
With this i am not able to save as well display on select box value.
echo $this->TwitterBootstrap->input("Attribute.Attribute.$i.value", array(
'type' => 'select',
'options' => $options ,
'value' => $attribute_value['value'],
'label' => $entityAttribute['Attribute']['name'],
'empty' => $entityAttribute['Attribute']['required'] ? false : __('-- None --'),
));
Your array should look like:
$options => array("20"=>20,"30"=>30,"40"=>40);
and if $i is a variable, then write it like:
echo $this->TwitterBootstrap->input("Attribute.Attribute".$i."value",...
In Cake, we can add url in image() like this:

How to add class and others attributes to a tag?

array(

'escape' => false //to allow the image tag within the link

I've installed Miles Johnson's Uploader plugin and set it up with one of my models and got it working perfectly. Very nice.
Then I went and set it up on another model with almost identical code [the only difference is the upload path] and it won't work on the second model. When I submit the form the plugin doesn't seem to notice; I get an SQL error from an attempt to insert the POST file array straight into the DB.
Here is the code. [Other than this the plugin is imported in the bootstrap]
public $actsAs = array(
'Uploader.Attachment' => array(
'photo' => array(
'name' => 'formatFileName',
'uploadDir' => '/uploads/uses/img/',
'dbColumn' => 'photo',
'maxNameLength' => 30,
'overwrite' => true,
'stopSave' => true,
'allowEmpty' => false,
'transforms' => array(
array('method' => 'resize', 'width' => 240, 'dbColumn' => 'photo_thumb'))
)
),
'Uploader.FileValidation' => array(
'fileName' => array(
'extension' => array('gif', 'jpg', 'png', 'jpeg'),
'required' => true
)
)
);
This is on the model that is not uploading and the only difference is the uploadDir.
Does the plugin only work on one model? Any clues? thnx :}
Edit for extra clarity
Here is my view code:
echo $this->Form->create('Use', array('type' => 'file'));
echo $this->Form->input('Use.photo', array('type' => 'file'));
echo $this->Form->input('Use.desc', array('rows' => '3', 'label' => 'Description'));
echo $this->Form->end('Add to Gallery');
And here is my controller code:
public function add() {
if ($this->request->is('post')) {
$this->Use->set('user_id', $this->Auth->user('id'));
if ($this->Use->save($this->request->data)) {
$this->Session->setFlash('Your Use has been saved.');
$this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash('Unable to add your Use.');
}
}
}
The plugin doesn't work in only one model. You can add more uploader into your site.
The model seems to be good, I suggest you to see into your form to see if you have create the form in the right way into your view (is imporant to put into your form: 'type' => 'file'
example:
echo $this->Form->create('Product', array ('class' => 'form', 'type' => 'file'));
echo $this->Form->input('ModelImage.filename', array('type' => 'file'));
echo $this->Form->submit('Add Image', array('id'=>'add_image'));
echo $this->Form->end();
Or the problem is the name Use try to change the name with another
After checking thru the code with Alessandro [thank you :)] I found the problem.
If you look in the View and Controller code you can see that the model is named 'Use'. This was the problem, as Use is a loaded word in PHP and I shouldn't have used it for a model name.
I renamed the model to Outcome and now the Uploader works perfectly.
I have two models, Category and Point. The associations are defined as:
Category hasMany Point
Point belongsTo Category
I would like, when adding Points to my database, to be able to select the category it belongs to from a <select> box, along with the rest of the form data.
Where would I need to set the category list and how could I do it? And how would I produce the select box?
I assume it could be done with
$form->input('categorieslist',array('type'=>'select')); //categorieslist needs
//setting somewhere.
Also to generalize a bit:
In a View with access to the Form helper
<?php
echo $form->input( 'dataKey', array(
'type' => 'select',
'options' => array(
'key1' => 'val1',
'key2' => 'val2',
),
));
?>
The above will render a select input with two options. You can also place an empty option as the first item. Passing a value of true will simply append an empty option with a blank value to the beginning of the options rendered in the HTML.
<?php
echo $form->input( 'dataKey', array(
'type' => 'select',
'options' => array(
'key1' => 'val1',
'key2' => 'val2',
),
'empty' => true,
));
?>
You can pass a string to the 'empty' key to have it display custom text as the key field for the empty option.
<?php
echo $form->input( 'dataKey', array(
'type' => 'select',
'options' => array(
'California' => 'CA',
'Oregon' => 'OR',
),
'empty' => 'choose a state',
));
?>
One last example, you can also pre-select an option with the selected key. The value should match the value of one of the select options, not the key.
<?php
echo $form->input( 'dataKey', array(
'type' => 'select',
'options' => array(
'California' => 'CA',
'Oregon' => 'OR',
),
'empty' => 'choose a state',
'selected' => 'California',
));
?>
From the Model
Model->find( 'list', array( ... )); will always return an array formatted for use with select box options. If you pass data to your view stored in a variable with a lowercase plural model name, that is, ( $this->set( 'categories', $categories );, then you will automagically generate drop downs for related models by using the form helper in the view and passing it a data index of the same model name in singular form suffixed with "_id".
Aziz's answer at #2 is the example of that automagic kicking in.
CakePHP 1.3 Form Helper
CakePHP1.2 Form Helper
In the controller:
$categories = $this->Point->Category->find('list');
$this->set(compact('categories'));
In the view:
$form->input('category_id',array('type'=>'select'));
