I have a form with a element called "price". I validate this element with the "float" validator. The thing is when I insert, for example:
12,50 => it is valid but when I try to save it on the DB (mysql) it is saved as "12.00"
So I wanna to change the decimal character from "," to ".". Does anybody knows how??
Note. If I put:
$price->addValidator('Float', 'de')
or
$validator = new Zend_Validate_Float(array('locale' => 'de'));
$price->addValidator($validator)
It does not work.
You can use a filter Zend_Filter LocalizedToNormalized to it will normalized you localized price according to the user's locale.
A typical price element would be like this one:
$price = new Zend_Form_Element_Text('price');
$price->setLabel('Price:')
->setRequired(true)
->setAttribs(array('required name' => 'price', 'maxlength' => '12'))
->addFilter('StripTags')
->addFilter('StringTrim')
->addFilter('pregReplace', array('match' => '/\s+/', 'replace' => ''))
->addFilter('LocalizedToNormalized')
->addValidator('stringLength', true, array(1, 12))
->addValidator('float', true, array('locale' => 'en_US'))
->addValidator('greaterThan', true, array('min' => 0));
$this->addElement($price);
Of course, you can improve it and add the validators/filters you need.

I'm trying to combine two data into one column. I already managed to combine two data in one column. But my problem is I don't know how to do a break line to separate the data. I have tried this way but doesn't work.
This is my code
'NAME_PROG_ENG'.'REMARKS' => ['label' => "Programme Name",'value' => function ($data) {return ($data->NAME_PROG_ENG)."\r\n".nl2br("Previously known as: ".($data->REMARKS));}],
I think you refer to GridView component.
Some explanation:
'NAME_PROG_ENG'.'REMARKS' =>
the array index is the model field name, you can't combine 2 columns just by concatenating the column name. In this way you just define a column in the grid wich is not connected to the model. This is not an error, is just to notice that this does not give you the expected result.
'value' => function ($data) {return ($data->NAME_PROG_ENG)."\r\n".nl2br("Previously known as: ".($data->REMARKS));}
Between $data->NAME_PROG_ENG and $data->REMARKS you put a "\r\n" which is fine, but you apply nl2br() function only to the second part of the string.
Now about Gridview. Text are automatically converted to entities, this is a security feature to avoid script injection from user input. If you plan to use input from an untrusted user, ensure that you clean it using htmlpurifier before saving it in database or before showing it (in your 'value'=>... function)
https://www.yiiframework.com/search?language=en&version=2.0&type=guide&q=htmlpurifier
You can bypass html entity conversion by specifies the output format as raw in grid column option
'format'=>'raw'
So you column definition should be something like
'prog_and_remark_combined' => [
'format' => 'raw',
'label' => "Programme Name",
'value' => function ($data) {
return nl2br(
$data->NAME_PROG_ENG .
"\r\nPreviously known as: " .
$data->REMARKS
);
}
],
Gridview allow a short notation
https://www.yiiframework.com/doc/api/2.0/yii-grid-gridview#$columns-detail
which is like this
<column name>:<fomat>:<label>
your code can be as follow as well
'prog_and_remark_combined:raw:Programme Name' => [
'value' => function ($data) {
return nl2br(
$data->NAME_PROG_ENG .
"\r\nPreviously known as: " .
$data->REMARKS
);
}
],
Last note, if the fields does not contain new line to be converted, just concatenate them without using nltobr() function
return $data->NAME_PROG_ENG . "<br>Previously known as: " . $data->REMARKS
I have a tree node in my form. I am using kartik-v's Tree Manager.
This is my view code:
echo TreeViewInput::widget([
'query' => Tree::find()->addOrderBy('root, lft'),
'headingOptions' => ['label' => 'Set Permission'],
'name' => 'name',
'value' => '1,2,3',
'asDropdown' => false,
'multiple' => true,
'fontAwesome' => true,
'rootOptions' => [
'label' => '<i class="fa fa-tree"></i>',
'class' => 'text-success'
]);
But, in this I have to follow the same table structure as mentioned in the widget. I have some extra fields and more permissions. So it is a bit complicated to use the same structure.
Is it possible to pass the value in an array directly to this widget? If possible let me know the array format.
Now I am stuck with this tree node implementation.
You can do this by doing some tricks, or by using another way:
1) you can add a condition to your query like this:
Tree::find()->andWhere(['not in','id',[2,3,4]])->addOrderBy('root, lft'),
by this solution you can ignore unwanted rows like you send data direct in array...
2) you can use another solution by using js lib/plugin direct like jsTree, in this case you can create and pass custom array direct...look at this example: jsTree Example
I have a Model who has a column (attribute) that stored a comma separated value of IDs.
For Example,
Movie has a column "Genre" that includes more than one genre, e.g.: 40,20,1,3
How can I use Select2 widget to show these values separated when 'multiple' => true
And how can I save them back into comma-separated value as a string. I want a solution that will allow for quick flexibility. I know you can implode and explode the string but seems too much.
Any help appreciated
If I remember correctly pass the default option as part of the $options configuration for the widget:
echo $form->field($model, 'model_attribute_name')->widget(Select2::className(), [
'data' => $data
'options' => [
'class' => 'form-control',
'placeholder' => 'Choose Option...',
'selected' => 40
],
'pluginOptions' => [
'allowClear' => true,
],
])->label('Select2 Form Field');
This is from memory for grain fo salt here. The documentation at http://demos.krajee.com/widget-details/select2 is not very specific about how to do this.
I don't believe you can do that. Select2 sends the data in post as an array, so you would still need to use implode before saving. What i would do instead is in your model class:
class MyModel extends \yii\db\ActiveRecord {
$public myArrayAttribute;
...
public function beforeSave($insert) {
if (parent::beforeSave($insert)) {
$this->myAttribute = implode(',', $this->myArrayAttribute);
return true;
}
return false;
}
public function afterFind() {
parent::afterFind();
$this->myArrayAttribute = explode(',', $this->myAttribute);
}
}
This way myArrayAttribute will hold the values from the comma separated field as an array. Of course you will need to add validation rules for it and use it instead of your other attribute in create and update forms.
if you're displaying a form with already populated fields, maybe you want to update an already existing object, and you want to display the already saved value for the Select2 field, use 'data' => [ 1 => 'Some value' ], where 1 is the value, associated to the value displayed in the form. You can retrieve stuff to put in data from DB beforehand.

I have a Year field in a form and I am using FormHelper.
echo $this->Form->input('year', [
'type' => 'year',
'minYear' => date('Y')-10,
'maxYear' => date('Y')
]);
The table file validator looks like:
->add('year', 'valid', ['rule' => 'numeric'])
->allowEmpty('year')
I have a very similar input in another app that seems to work fine. I set the MySql column to int(5) to match what I had working elsewhere.
Checking debugkit it shows the "year" input as an array while the other inputs are strings. If I remove the validation rule it throws an illegal array to string conversion, so I assume this is where the error is.
Any help is greatly appreciated.
I have just tested with your above code and it is working fine for me. Try to delete the cache and check it once more.
Creates a select element populated with the years from minYear to maxYear. Additionally, HTML attributes may be supplied in $options. If $options['empty'] is false, the select will not include an empty option:
empty - If true, the empty select option is shown. If a string, that
string is displayed as the empty element.
orderYear - Ordering of
year values in select options. Possible values ‘asc’, ‘desc’. Default
‘desc’ value The selected value of the input.
maxYear The max year to
appear in the select element.
minYear The min year to appear in the
select element.
Try this one:
<?php
echo $this->Form->year('exp_date', [
'minYear' => date('Y')-10,
'maxYear' => date('Y'),
'id' => 'cc-year',
'class' => 'form-control',
'empty' => false,
'orderYear' => 'asc'
]);
?>

I'm trying to create an AJAX form whereby the content of a select field populates based on the choice of a preceding select field (you see this a lot with 'country' populating 'state/province'). In my case, I want users to be able to choose their province only if active accounts exist in it.
The Javascript I can write no problem. Fetching the data is where I'm... not so much stuck as doing too much work. CakePHP likes to build select fields with options in an array of the form
$options = array(select_option_value => display_text)
My strategy, though functional, must be more convoluted than cake intended (this a is segment of a controller method).
$provinceData = $this->Account->find('all',array('recursive' => 0,
'joins' => array(
array(
'table' => 'provinces',
'type' => 'LEFT',
'conditions' => array('Account.province_id = provinces.id')
)),
'fields'=>array('provinces.id', 'provinces.name', 'provinces.abbrev'),
'conditions' => array('registration > 2')));
$provinces = array();
foreach($provinceData as $pd) {
/*note: lowercase, plural below b/c can't get 'alias' => 'Province'
to work in joins array above : ( */
$id = $pd['provinces']['id'];
$name = $pd['provinces']['name'];
$provinces[$id] = $name;
}
$this->set(compact('provinces'));
Can anyone point out a more appropriate way to do this? I assume there must be a MySQL query that can do this, but I'm pretty bad at writing elaborate MySQL queries in the first place, let alone via Cake's convention (and, for you MySQL gurus out there, I'm happy to do this from a Model->query(//MySQL code) call instead!
Any and all help truly appreciated.
Assuming the relationship Account belongsTo Province you can try this code:
$accounts = $this->Account->find(
'all',
array(
'fields' => array('Account.province_id', 'Province.name'),
'conditions' => array('Account.registration > 2'),
'group' => 'Account.province_id'
)
);
$provinces = Hash::combine($accounts, '{n}.Account.province_id', '{n}.Province.name');
$this->set(compact('provinces'));
edit: missed bracket and a period instead of an underscore . Now should work
