I have a _form.php file with this field:
<?=
$form->field($model, 'price')
->textInput([
'class' => 'form-control',
'type' => 'number'
])
?>
The price has this format 1234.50. I would like to have the format es-AR, like this: 1234,50.
In the GridView of index.php I use this code and it works great so I would like to do the same in the _form but it is not working.
[
'attribute' => 'price',
'value' => function($myModel) {
$myFormat = new NumberFormatter("es-AR", NumberFormatter::CURRENCY);
return $myFormat->formatCurrency($myModel->price, "ARS");
},
]
There are 2 ways to do that:
Add extra class to the price field and use javascript to convert to format you want (remember to return it back on submit)
Create priceFormat() and use it on AfterFind event and remember to use priceUnFormat() to return to decimal on BeforeSave
Use:
$form->field($model, 'attr', ['inputOptions' => ['value' => Yii::$app->formatter->asDecimal($model->attr)]])

I have fields like below
<?= $form->field($model, 'phone')
->textInput(['type' => 'number', 'maxlength' => 13])
->label('Phone')
?>
why the 'maxlength' is not work? and how to make it work?
thank you before
It will not work because you are using type=>number for your input field, you have to change it to type=>text.
<?= $form->field($model, 'phone')
->textInput(['type' => 'text', 'maxlength' => 13])
->label('Phone')
?>
Looking at your input it seems like you are doing it because you do not want the user to enter any other thing than numbers for the Phone field, Yii2 provides you a very nice way to accomplish this i.e yii\widgets\MaskedInput, you can format your input using the mask option to tell it how many digits to allow and in which sequence see the demos HERE
<?= $form->field($model, 'phone')->widget(\yii\widgets\MaskedInput::className(), [
'mask' => '999-999-9999',
]) ?>
apart from the solutions above, you can also have the option of validating this inside your model by using the custom validation option.
Your rule for phone inside your model should look like
[['phone'],'PhoneLimit']
public function PhoneLimit($attribute)
{
if (!preg_match('/^[0-9]{13}$/', $this->$attribute)) {
$this->addError($attribute, 'Please provide digits only no more than 13.');
}
}
try for type number -> 'type'=>'number', 'min' => 1, 'max' => 999
I am using a Select2 widget for Yii2. It shows a list with the ids of the users.
I need to show two fields defined in my model called Users: first_name_user and last_name_user. Like this:
Daniel Gates
John Connor
John Doe
Maria Key
But I don't know how use map() to show more than one field.
<?= $form
->field($model, 'id_user')
->widget(\common\widgets\Select2::classname(), [
'items' => \yii\helpers\ArrayHelper::map(\app\models\Users::find()->orderBy('name_user')->all(), 'id_user', 'name_user')
])
?>
Model
Add use app\models\Users; and use yii\helpers\ArrayHelper; at top.
public function userList()
{
$userList = [];
$users = Users::find()->orderBy('first_name_user')->all();
$userList = ArrayHelper::map($users, 'id_user', function ($user) {
return $user->first_name_user.' '.$user->last_name_user;
});
return $userList;
}
_form
<?= $form->field($model, 'id_user')->widget(Select2::className(), [
'data' => $model->userList(),
'options' => ['placeholder' => 'Select User'],
]) ?>
You need to use data option instead of items for Select2.
You need to modify your query to show the concatenated first_name_user and last_name_user as an alias and then return it along with the id column to be used in Select2 by ArrayHelper::map().
It's better to add a function to the model you are using to populate the form and return the results from there to the ArrayHelper::map().
Your query should look like
function userList(){
return \app\models\Users::find()
->select([new \yii\db\Expression('[[id_user]],CONCAT([[first_name_user]]," ",[[last_name_user]]) as full_user_name')])
->orderBy('name_user')
->all();
}
Your form field should look like below
<?=
$form->field($model, 'id_user')->widget(Select2::className(), [
'data' => \yii\helpers\ArrayHelper::map($model->userList(), 'id_user', 'full_user_name'),
'options' => [
'placeholder' => 'Select User',
'id' => 'id_user'
],
'theme' => Select2::THEME_DEFAULT,
'pluginOptions' => [
'allowClear' => true
],
]);
?>
Updates have been made below
I am trying to use the Kartik-V Typeahead Basic widget with the Yii2 Framework.
The code below is working to display the required data, the user can search via the university name and it appears in the autocomplete list.
The issue is, the model needs to the university id, not the name. Thus the rules are this field can only store an integer and returns a validation error once you select one of the typeahead results.
<?= $form->field($model, 'university_id')->widget(TypeaheadBasic::classname(), [
'data' => ArrayHelper::map(University::find()->all(),'id','uni_name'),
'pluginOptions' => ['highlight' => true],
'options' => ['placeholder' => 'Filter as you type ...'],
]); ?>
I am hoping someone can help me understand if there is a setting that needs to be changed so when saving, the user friendly 'uni_name' data is changed back to the uni 'id'.
UPDATE:
I have gotten the code partly working thanks to "Insane Skull".
The new code is:
<?= $form->field($model, 'name')->widget(TypeaheadBasic::classname(), [
'data' => ArrayHelper::map(University::find()->all(),'id','uni_name'),
'pluginOptions' => ['highlight' => true],
'options' => ['placeholder' => 'Filter as you type ...', 'id' => 'testID'],
'pluginEvents' => [
'typeahead:select' => new yii\web\JsExpression("function(event, ui) { $('#testing123').val(ui.item.id); }"),
]
]); ?>
<?= Html::activeHiddenInput($model, 'university_id', array ('id' => 'testing123'))?>
Now I am unfortunately getting the error:
Method yii\web\JsExpression::__toString() must return a string value
I would rather use Select2 instead of Typeahead, you are basically trying to implement the functionality that already exists on Select2 but using Typeahead.
<?= $form->field($model, 'university_id')->widget(Select2::classname(), [
'data' => ArrayHelper::map(University::find()->all(),'id','uni_name'),
'options' => ['placeholder' => 'Filter as you type ...'],
]); ?>
You can use activeHiddenInput() for this purpose.
Create one public variable in model say name.
Then:
<?= $form->field($model, 'name')->widget(TypeaheadBasic::classname(), [
'data' => ArrayHelper::map(University::find()->all(),'id','uni_name'),
'pluginOptions' => ['highlight' => true],
'options' => ['placeholder' => 'Filter as you type ...'],
'select' => new yii\web\JsExpression("function( event, ui ) {
$('#id_of_hiddenField').val(ui.item.id);
}")
]); ?>
<?= Html::activeHiddenInput($model, 'university_id')?>
And in Controller Get the value of activeHiddenField.
Yii2 active form
<?= $form->field($model, 'pid')->dropDownList([1=>1,2=>2])->hint('上级分类') ?>
I want to disable the option item 2=>2.
Is there a way to do it?
You can add attributes for all items in the dropdownlist with the 'options' key. Let's say you want to disable the second item.
<?= $form->field($model, 'pid')->dropDownList([1 => 1, 2 => 2], ['options' => [2 => ['disabled' => true]]])->hint('上级分类') ?>
In the docs:
http://www.yiiframework.com/doc-2.0/yii-helpers-basehtml.html#activeDropDownList()-detail
This would work definitely:
<?= $form->field($model, 'pid')->dropDownList([1=>1,2=>2], ['options'=>['2'=>['disabled'=>true]]]) ?>
ActiveField dropDownlist() explicitly calls BaseHtml activeDropDownList():
From the docs to ActiveField dropDownList():
The tag options in terms of name-value pairs.
For the list of available options please refer to the $options
parameter of yii\helpers\Html::activeDropDownList().
And from the docs to BaseHtml activeDropDownList():
options: array, the attributes for the select option tags. The array
keys must be valid option values, and the array values are the extra
attributes for the corresponding option tags. For example,
[
'value1' => ['disabled' => true],
'value2' => ['label' => 'value 2'],
];
So pass these options:
[
2 => ['disabled' => true],
],
as second parameter to dropDownList().
Try this:
$disableDataArr['1'] = ['disabled' => true];
dropDownList( $dataArr, ['options'=> $disableDataArr ])
I want to show selected value in Yii2 dropdown,
$_GET Value:
$id = $_GET["cid"];
Drop down code
$form->field($model, 'userid')
->dropDownList(
[User::getUser()],
//[ArrayHelper::map(User::findAll(['active' => '1']), 'id', 'name')],
['prompt'=>'Select a user','id'=>'user_dropdown'],
['options' =>
[
$id => ['selected' => true]
]
]
)->label('');
but this method is not working!
Try this.
$model->userid=$id;
$form->field($model, 'userid')
->dropDownList(...)
->label('');
Basically, you affect the options (your <option> elements) by using the value attribute's actual value as the array key in the dropDownList options array.
So in this case I have an array of states and the value attributes have the state abbreviation, for example value="FL". I'm getting my selected state from the Address table, which stores the abbreviation, so all I have to do is use that as my array key in the options array:
echo $form->field($model, 'state')->dropDownList($listData, ['prompt'=>'Select...', 'options'=>[$address->state=>["Selected"=>true]]]);
The documentation spells it out: http://www.yiiframework.com/doc-2.0/yii-helpers-basehtml.html#dropDownList()-detail
i hope this will help you
$form->field($model, 'userid')
->dropDownList(
[User::getUser()],
//[ArrayHelper::map(User::find()->where('id' => $id)->all(), 'id', 'name')],
['prompt'=>'Select a user','id'=>'user_dropdown'],
['options' =>
[
$id => ['selected' => true]
]
]
)->label('');
$model->userid = $_GET['cid'];
$form->field($model, 'userid')
->dropDownList(
$items, //Flat array('id'=>'val')
['prompt'=>''] //options
)->label('');
<?php
$selectValue = $_GET['tid']
echo $form->field($model, 'tag_id')
->dropdownList(
ArrayHelper::map(Tag::find()->where(['visibility'=>'1'])->orderBy('value ASC')->all(), 'tag_id', 'value'),
['options' => [$selectValue => ['Selected'=>'selected']]],
['prompt' => '-- Select Tag --'])
->label(false);
?>
This code will Auto Select the selected value received as input.
Where $selectValue will be numeric value received from GET method.
Final output : <option value="14" selected="selected">NONE</option>
Ok, if you are using ActiveForm then value of your model field will be used as the selected value. With Html helper dropDownList function accepts another parameter selection doc. Example:
$id = $_GET["cid"];
\yii\helpers\Html::dropDownList('userid', $id, [ArrayHelper::map(User::findAll(['active' => '1']), 'id', 'name'), [......])
This is my S.O.L.I.D approach.
Controller
$model = new User();
$model->userid = $id; #this line does the magick. Make sure the $id has a value, so do the if else here.
return $this->return('view', compact('model'))
But, if you prefer the setter method. Do this...
# Model
class User extends ActiveRecord
{
public function setUserId(int $userId): void
{
$this->userid = $userId;
}
}
# Controller
$model = new User();
$model->setUserId($userId);
View (view is as-is)
$form->field($model, 'userid')
->dropDownList(...)
->label('');
Use this code below:
$category = \backend\models\ProductCategory::find()->WHERE(['deleted'=>'N'])->all();
$listData = ArrayHelper::map($category,'product_category_id','category_name');
echo $form->field($model, 'product_category_id')->dropDownList($listData,['prompt'=>'Select']);
All of the options I've added are unrequired.
What is written in the 'value' index is what dropdown item will be selected as default.
Prompt just displays a first option that doesn't have a value associated with it.
echo $form->field($model, 'model_attribute_name')
->dropDownList($associativeArrayValueToText,
[
'value'=> $valueIWantSelected,
'prompt' => 'What I want as a placeholder for first option',
'class' => 'classname'
]);
You'll find the function that assigns this in the following file:
vendor/yiisoft/yii2/helpers/BaseHtml.php
public static function renderSelectOptions($selection, $items, &$tagOptions = [])
Also from the function you can see that you can add an optgroup to your dropdown, you just need to supply a multidimensional array in where I've put $associativeArrayValueToText. This just means that you can split your options by introducing group headings to the dropdown.
