I am new to this framework, and in the english language too (haha).
But here is my problem:
I do some code using the belongsto of the cake. I think I did everything right. But when I click submit, he only register the information of the table and dont do the association.
My tables:
Planos
Servidores
Servidores_Planos
My code:
table/PlanosTable.php
$this->belongsToMany('Servidores', [
'class' => 'servidores',
'joinTable' => 'servidores_planos',
'foreignKey' => 'planos_id',
'targetForeignKey' => 'servidores_id'
]);
table/ServidoresTable.php
$this->belongsToMany('Planos', [
'joinTable' => 'servidores_planos',
'foreignKey' => 'servidores_id',
'targetForeignKey' => 'planos_id'
]);
I dont think it is necessary to show the controller code, because the add page from planos receive the servidores.
And this is my input in add page.
<?php echo $this->Form->input('servidores.id',array('type'=>'select','multiple','label'=>false,'id'=>'selectServidor', 'class'=>'form-group', 'name' => 'servidores[]', 'options'=> $servidores,'style' => 'width:430px;height:180px;')); ?>
You just need to modify your view slightly. Try this :
echo $this->Form->input('servidores._ids', [
'type' => 'select',
'multiple' => true,
'label' => false,
'id' => 'selectServidor',
'class' => 'form-group',
//'name' => 'servidores[]', /* This name field is generated automatically */
'options' => $servidores,
'style' => 'width:430px;height:180px;'
]);
This should solve your issue. In your controller, make sure you're following the convention and passing the appropriate parameters for saving associated data.
Hope this helps.
Peace! xD

Has anyone here ever created a nested dropdown within the backpack's cruds?
I've got this crud controller which handles the 'Campaign' model -
$this->crud->addField([
'name' => 'industry_id',
'entity' => 'industry',
'type' => 'select2',
'attribute' => 'name',
'label' => "Industry",
]);
$this->crud->addField([
'name' => 'country_id',
'entity' => 'country',
'type' => 'select2',
'attribute' => 'country_name',
'label' => "Country",
]);
$this->crud->addField([
'name' => 'website_id',
'entity' => 'website',
'type' => 'select2',
'attribute' => 'name',
'label' => "Website",
]);
$this->crud->addField([
'name' => 'campaign_type_id',
'entity' => 'campaign_type',
'type' => 'select2',
'attribute' => 'name',
'label' => "Campaign Type",
]);
$this->crud->addField([
'name' => 'site_page_id',
'entity' => 'site_page',
'type' => 'select2',
'attribute' => 'name',
'label' => "Site Page",
]);
The 'website' entity depends on the industry field, and the 'site_page_id' depends on the cross between the 'website' entity and the 'campaign_type' entity.
When I'm creating a new campaign, I'm willing the dropdowns to be filled up dynamically according to the selected value of the dropdown above them.
I tried adding a method to the campaign's model as suggested in this pull and call it within the crud field's but it didn't work.
The only solution I can think of now is creating a custom create.blade.php file and call it with $this->crud->setCreateView('vendor.backpack.base.new_create'); from campaign's model setup() method.
You can use
$this->crud->with();
or
$this->crud->with(['website', 'site_page']);
It will get all the duplicate data in the relationships.
Let me know if this helped
I'm new at yii and trying to find my way around. I have done a tutorial or two. I then decided to start editing/changing the example to allow me to learn more. I created a page that does a simple PING. That gets validated. On success, it loads a static page. This all works.
What I wanted to do next is to see how I can utilize a grid to populate that with some data. My real life example is the same. I will get a array of data coming in.
It seems that CArrayDataProvider is what I need. So, I am trying to get a very simple example to work. If I get this to work, I can move on.
I have tried a whole bunch of examples. The error is the same every time. It seems that I do not have CArrayDataProvider installed? If that is even possible.
I did a standard basic install:
composer create-project --prefer-dist yiisoft/yii2-app-basic basic
I have the following at the beginning of my controllers file:
use yii2\data\ArrayDataProvider;
I get no error here.
I searched for the file itself on the file system, could not find it. I did find ArrayDataProvider, so I tried that, same result:
use vendor\yiisoft\yii2\data\ArrayDataProvider;
The error is:
PHP Fatal Error – yii\base\ErrorException
Class 'CArrayDataProvider' not found
This is on line 24:
"dataProvider = new CArrayDataProvider($fruits);"
Here is my example code. Not that I think the issue is in here, but to show what I am trying to do:
$fruits = array(
array('id' => 1, 'name'=>'apple', 'color' => 'green'),
array('id' => 2, 'name'=>'orange', 'color' => 'orange'),
array('id' => 3, 'name'=>'banana', 'color' => 'yellow'),
array('id' => 4, 'name'=>'pineapple', 'color' => 'brown')
);
$dataProvider = new CArrayDataProvider($fruits);
$this->widget('zii.widgets.grid.CGridView', array(
'id' => 'fruits-grid',
'dataProvider' => $dataProvider ,
'columns' => array(
array(
'name' => 'ID',
'value' => '$data["id"]',
),
array(
'name' => 'Name',
'value' => '$data["name"]'
),
array(
'name' => 'Color',
'value' => '$data["color"]'
),
)
));
On the file-system (linux) itself I did a update:
composer update
I have been Googling for the last 2 days and I am finding nothing.
I tried adding a date picket. That worked. I used:
https://www.tutorialspoint.com/yii/yii_extensions.htm
So in short, the static page that I call, now displays a DateTimePicker.
At the start of the file I added:
use kartik\datetime\DateTimePicker;
And in the body:
<?php
echo DateTimePicker::widget([
'name' => 'dp_1',
'type' => DateTimePicker::TYPE_INPUT,
'value' => '23-Feb-1982 10:10',
'pluginOptions' => [
'autoclose'=>true,
'format' => 'dd-M-yyyy hh:ii'
]
]);
?>
How do I get yii2 to allow me to use ArrayDataProvider. Or how do I install the extension? Or who do I reference it?
In Yii2 there's not a CArrayDataProvider. Use ArrayDataProvider, like described in docs:
$provider = new yii\data\ArrayDataProvider([
'allModels' => $query->from('post')->all(),
'sort' => [
'attributes' => ['id', 'username', 'email'],
],
'pagination' => [
'pageSize' => 10,
],
]);
Pretty well documented here.
Yii2 supports ArrayDataProvider and yii 1.* supports CArrayDataProvider, so as per your code you are using Yii2, so just replace the below line with
$dataProvider = new CArrayDataProvider($fruits);
With this:
$dataProvider = new ArrayDataProvider($fruits);
Thx to everyone's help! I now have a working example.
In case anyone else has the same issues, I will post my working code here:
use kartik\grid\GridView;
$resultData = [
array("id"=>1,"name"=>"Cyrus","email"=>"risus#consequatdolorvitae.org"),
array("id"=>2,"name"=>"Justin","email"=>"ac.facilisis.facilisis#at.ca"),
array("id"=>3,"name"=>"Mason","email"=>"in.cursus.et#arcuacorci.ca"),
array("id"=>4,"name"=>"Fulton","email"=>"a#faucibusorciluctus.edu"),
array("id"=>5,"name"=>"Neville","email"=>"eleifend#consequatlectus.com"),
array("id"=>6,"name"=>"Jasper","email"=>"lectus.justo#miAliquam.com"),
array("id"=>7,"name"=>"Neville","email"=>"Morbi.non.sapien#dapibusquam.org"),
array("id"=>8,"name"=>"Neville","email"=>"condimentum.eget#egestas.edu"),
array("id"=>9,"name"=>"Ronan","email"=>"orci.adipiscing#interdumligulaeu.com"),
array("id"=>10,"name"=>"Raphael","email"=>"nec.tempus#commodohendrerit.co.uk"),
];
$dataProvider = new \yii\data\ArrayDataProvider([
'key'=>'id',
'allModels' => $resultData,
'sort' => [
'attributes' => ['id', 'name', 'email'],
],
]);
echo GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'id',
[
'attribute' => 'name',
'value' => 'name',
],
[
"attribute" => "email",
'value' => 'email',
]
]
]);
I am getting the error:
The input was not found in the haystack
After form post. Please see the selection tag code lines below:
// Add "roles" field
$this->add([
'type' => 'select',
'name' => 'roles',
'attributes' => [
'multiple' => 'multiple',
'options'=>$this->role_desc,
'inarrayvalidator' => false,
'class'=>'form-control'
],
'options' => [
'label' => 'Role(s)',
],
]);
// Add input for "roles" field
$inputFilter->add([
'class' => ArrayInput::class,
'name' => 'roles',
'required' => true,
'haystack'=>$this->role_ids,
'filters' => [
['name' => 'ToInt'],
],
'validators' => [
['name'=>'GreaterThan', 'options'=>['min'=>1]],
['name'=>'InArray', 'options'=>['haystack'=>$this-
>role_ids]]
],
]);
The InArray seems to be validating well, lm just no sure what is bringing up the exception. Thank you in advance.
Actually , your issue is similar to link
To solve this, change your validators definition to:
'validators' => [
['name'=>'GreaterThan', 'options'=>['min'=>1]],
[
'name' => 'Explode',
'options' => array(
'validator' => [
'name'=>'InArray',
'options'=> [
'haystack'=>$this->role_ids
]
]
)
]
],
Unfortunately, I do not think there is a "cleaner" way to do this.
Alternately, Maybe you could use the MultiCheckbox.
I'm pretty new with Yii2 and have the next unpleasant issue.
I created two forms at same page like
<?php $form = ActiveForm::begin([
// make sure you set the id of the form
'id' => 'create',
'action' => $action,
'options' => ['enctype' => 'multipart/form-data']
]); ?>
<?php $form = ActiveForm::begin([
// make sure you set the id of the form
'id' => 'update',
'action' => $action,
'options' => ['enctype' => 'multipart/form-data']
]); ?>
I use the same model for both form fields like
<?= $form->field($action_model, 'action_name',[
'addon' => ['prepend' => ['content'=>$action_model->getAttributeLabel('action_mobile')]]
])->widget(Typeahead::classname(), [
'options' => ['placeholder' => $action_model->getAttributeLabel('action_placeholder')],
'pluginOptions' => ['highlight'=>true],
'dataset' => [
[
'local' => Json::encode( $totalLookUp['action_lookUp'] ),
'limit' => 10
]
]
])->label(false);
?>
And here is the issue. In that case I have two forms with same scope of fields, with same names and same id. What for sure will be not valid for W3C. The another one issue that inspite of that fact that client side presubmit javascript validation for both forms work perfect. The typeahed widget works only for first set of fields since it bindid by id.
If i try to override elements id by specify it by widgets options like
<?= $form->field($action_model, 'action_name',[
'addon' => ['prepend' => ['content'=>$action_model->getAttributeLabel('action_mobile')]]
])->widget(Typeahead::classname(), [
'options' => ['id'=> $form_id.'_action_name',
'placeholder' => $action_model->getAttributeLabel('action_placeholder')],
'pluginOptions' => ['highlight'=>true],
'dataset' => [
[
'local' => Json::encode( $totalLookUp['action_lookUp'] ),
'limit' => 10
]
]
])->label(false);
?>
The typeahead works perfect, but in that case validation fails, I mean it just stop working.
So the questuion is, how to make possible adjust validation script and use unique form id's.
From the docs:
If you set a custom id for the input element, you may need to adjust the $selectors accordingly.
For your case:
$form->field($action_model, 'action_name', [
'selectors' => ['input' => '#'.$form_id.'_action_name'],
'addon' => ...
I want to sort a column in TbJSONGridView by date , I have this code
$this->widget(
'bootstrap.widgets.TbJsonGridView', array(
'dataProvider' => $model->searchPending(),
'type' => 'striped bordered condensed',
'summaryText' => false,
'cacheTTL' => 10, // cache will be stored 10 seconds (see cacheTTLType)
'cacheTTLType' => 's', // type can be of seconds, minutes or hours
'enablePagination' => true,
'columns' => array(
array(
'name' => 'Pickup Date',
'value' => '$data->carShippeds[0]->pickup_date',
'type'=>'date',
),
))
but the column I get it is from a related model, and the sorting is not working, when I clicked on the column header it does nothing.
what's wrong with the code???
Gabriel
$data->carShippeds[0]->
This shows us that the current model has many cars shipped. You are only showing the first one in there. While that works, Yii has no way of knowing that you are only showing the first value so your sorting has no chance of working. Create a view that only selects your first pickup date, make a join in your criteria with the main model, show the field without [0]-> and it will work.
Change the below section:
array(
'name' => 'Pickup Date',
'value' => '$data->carShippeds[0]->pickup_date',
'type'=>'date',
),
To this:
array(
'name' => 'pickup_date',
'header' => 'Pickup Date',
'value' => '$data->carShippeds[0]->pickup_date',
'type'=>'date',
),
Then in your 'form' when you want to return DataProvider write the specific sorting code for this association like below:
return new DataProvider($query, [
'pagination' => [
'pagesize' => 20,
],
'sort' => [
'sortVar' => 'sort',
'defaultOrder' => ['t.carShippeds.pickup_date asc'],
'attributes' => [
'pickup_date' => [
'asc' => 't.carShippeds.pickup_date',
'desc' => 't.carShippeds.pickup_date DESC',
],
'*',
],
],
]);
Please notice that I did not know the join alias you have for your t.carShippeds or even whether it is t or another entity. replace it or give me more information about your DataProvider and I can help more.
