Can anyone have a suggestion about how to use "on" => "insert" validation in yii2?
I have used
array('field_name', 'required', 'on'=>'insert')
in Yii1 but in yii2 it does not check if I set
['field_name', 'required', 'on'=>'insert']
.
What is the problem here can you please explain?
Thanks in advance.
You should simply set your model's scenario before validation :
$model->scenario = 'insert';
Since with Yii2 :
By default, a model supports only a single scenario named default
Read more : http://www.yiiframework.com/doc-2.0/guide-structure-models.html#scenarios
First define the scenario:
// scenario is set as a property
$model->scenario = 'insert';
OR
// scenario is set through configuration
$model = new User(['scenario' => 'insert']);
Then you may specify the rule as:
// for single field
['field_name', 'required', 'on' => 'insert'],
// for multiple fields
[['field_name1','field_name2'], 'required', 'on' => 'insert'],

i develop a custom module with forms to save data in SQL-Datebase. I want to use for that the node-structure.
Normal SQL-savings for example table works but not for the node-tables.
Any idea what is going wrong?
This ist my Code for saving, which works in non-node-tables:
public function submitForm(array &$form, FormStateInterface $form_state) { $connection = \Drupal::service('database');
$result = $connection->insert('node.node__body')
->fields(['body_value'])
->values([
'body_value' => 'text for body',
])
->execute();
$form_state->setRedirect('modulname.form');
}
Use Entity API in Drupal to manipulate or create a node.
In your case,
$node = \Drupal::entityTypeManager()->getStorage('node')->create(
[
'type' => 'page',
'title' => 'New Basic Page',
'body' => 'text for body'
]
);
Here, type is the content type machine name. Don't forget to update with your own. Also you probably want to inject the entity_type.manager service and use in the code.

What is the right way to have variable pagination in Yii2?
I mean by this, that I want the user to be able to give the number of items in a page while sending an API request.
I know about setting the pageSize in the dataProvider.
$dataProvider = new SqlDataProvider([
'sql' => 'SELECT * FROM user WHERE status=:status',
'params' => [':status' => 1],
'pagination' => [
'pageSize' => 20,
],
]);
But my question is about anything that is built in that allows the user to send the pageSize through the request? Is there anything built-in to perform this function?
Leave empty the pagination field in the dataProvider and just add the per-page GET parameter in your calls:
http://your_url/controlller/action?per-page=20
More info here.
I have my pagination url set to
www...com/category/detail.html?page=2
For which my code is,
$dataProvider = new CActiveDataProvider('Page', array('criteria' => array('condition' => 'status=1', 'condition' => 'category_id=' . $categoryObject -> id, 'order' => 'postDate DESC'), 'pagination' => array('pageSize' => 4,'pageVar'=>'page'), ));
$dataProvider->getData();
var_dump $dataProvider->totalItemCount;
I am getting the exact data counts and my pagination url seems working. I have my URL rule configured as
'index'=>'site/index',
'contact'=>'site/contact',
'privacy'=>'site/privacy',
'sitemap.xml'=>'site/sitemap',
'<category:\w+>' => 'category/detail',
'<category>/page/<page:\d+>' => 'category/detail',
'<category>'=>'category/detail',
'<category:\w+>/<postTitle:.+>' => 'category/post',
'<category:\w.+>/<postTitle:.+>'=>'category/post',
my auto generated pagination URl are working fine but,
If I manually insert url something like
www......com/category/detail.html?Page_page&page=2
www......com/category/detail.html?Page_pizza&page=2
or any stupid things I can put they navigates to the page.
Now, here I want to remove these extra parameters or I want my pagination url to be strict to
www...com/category/detail.html?page=2
and if I put any additional params I want an error page.
I have been working in this for 2 weeks and tried every possible ways I could.
You should set the "params" property of the pagination to an empty array:
'pagination' => array('pageSize' => 4,'pageVar'=>'page', 'params' => array()),
This will avoid exclude any GET parameters from pagination links(if you need any included, add their name there).
To throw an error, you need to check for the parameters in your action.
// remove valid prameters from get array.
$arr = array_diff_key($_GET, array_flip(array('page', 'postTitle', 'category')));
// if still there are parameters left, throw an error.
if(count($arr) > 0) {
throw new CHttpException('invalid parameter');
}
I'm creating a back-office module for Prestashop and have figured out everything except the best way to display the admin page. Currently I'm using the renderView() method to display the content of view.tpl.
I would like to display a table with values and an option to add a new row. Should I just create it in the view.tpl or is there a better way? I've seen the renderForm() method but haven't figured out how it works yet.
The biggest question I have is, how do I submit content back to my controller into a specific method?
ModuleAdminController is meant for managing some kind of records, which are ObjectModels. Defauly page for this controller is a list, then you can edit each record individually or view it's full data (view).
If you want to have a settings page, the best way is to create a getContent() function for your module. Besides that HelperOptions is better than HelperForm for this module configuration page because it automatically laods values. Define the form in this function and above it add one if (Tools::isSubmit('submit'.$this->name)) - Submit button name, then save your values into configuration table. Configuration::set(...).
Of course it is possible to create some sort of settings page in AdminController, but its not meant for that. If you really want to: got to HookCore.php and find exec method. Then add error_log($hook_name) and you will all hooks that are executed when you open/save/close a page/form. Maybe you'll find your hook this way. Bettter way would be to inspect the parent class AdminControllerCore or even ControllerCore. They often have specific function ready to be overriden, where you should save your stuff. They are already a part of execution process, but empty.
Edit: You should take a look at other AdminController classes, they are wuite simple; You only need to define some properties in order for it to work:
public function __construct()
{
// Define associated model
$this->table = 'eqa_category';
$this->className = 'EQACategory';
// Add some record actions
$this->addRowAction('edit');
$this->addRowAction('delete');
// define list columns
$this->fields_list = array(
'id_eqa_category' => array(
'title' => $this->l('ID'),
'align' => 'center',
),
'title' => array(
'title' => $this->l('Title'),
),
);
// Define fields for edit form
$this->fields_form = array(
'input' => array(
array(
'name' => 'title',
'type' => 'text',
'label' => $this->l('Title'),
'desc' => $this->l('Category title.'),
'required' => true,
'lang' => true
),
'submit' => array(
'title' => $this->l('Save'),
)
);
// Call parent constructor
parent::__construct();
}
Other people like to move list and form definitions to actual functions which render them:
public function renderForm()
{
$this->fields_form = array(...);
return parent::renderForm();
}
You don't actually need to do anything else, the controller matches fields to your models, loads them, saves them etc.
Again, the best way to learn about these controller is to look at other AdminControllers.
I am working with the Yii framework.
I have set a value in one of my cgridview filter fields using:
Here is my jQuery to assign a value to the searchfield:
$('#gridviewid').find('input[type=text],textarea,select').filter(':visible:first').val('".$_GET['value']."');
And here my PHP for calling the cgridview:
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'bills-grid',
'dataProvider'=>$dataProvider,
'filter'=>$model,
'cssFile'=>Yii::app()->baseUrl . '/css/gridview.css',
'pager'=>array(
'class'=>'AjaxList',
'maxButtonCount'=>25,
'header'=>''
),
'columns' => $dialog->columns(),
'template'=>"<div class=\"tools\">".$dialog->link()." ".CHtml::link($xcel.' Export to excel', array('ExcelAll'))."</div><br />{items}{summary}<div class=\"pager-fix\">{pager}</div>",));
The value appears in the search field and my cgridview works correctly without any issues, but I am unable to trigger the cgridview to refresh or filter. Does anyone know who to trigger the cgridview to filter after page load with a predefined value?
Any help would be greatly appreciated and please let me know if you need additional information.
Thank you.
You can solve the problem without any clientside code modification. In your controller action just set the default value for the attribute as shown below
public function actionAdmin()
{
$model = new Bills();
$model->unsetAttributes();
$model->attribute_name="default filter value";//where attribute_name is the attribute for which you want the default value in the filter search field
if(isset($_GET['Bills'])){
$model->attributes = $_GET['Bills'];
}
$this->render('admin',array('model'=>$model));
}
Have a look at 'default' index action that gii generates:
public function actionIndex()
{
$model = new Bills();
$model->unsetAttributes();
if(isset($_GET['Bills'])){
$model->attributes = $_GET['Bills'];
}
$this->render('index',array('model'=>$model));
}
So if you add one line like: $model->attribute = 'test';, you're done. 'attribute' is of course the attribute that has to have the default filter value (in this case value is 'test') :). So your code looks like:
public function actionIndex()
{
$model = new Bills();
$model->unsetAttributes();
if(isset($_GET['Bills'])){
$model->attributes = $_GET['Bills'];
}
if(!isset($_GET['Bills']['attribute']) {
$model->attribute = 'test';
}
$this->render('index',array('model'=>$model));
}
Of course youre attribute will have a test value (in filter) set up as long as you wont type anything in its filter field. I hope that that's what you're looking for. Your filter should work as always.
Sorry for my bad english :)

You can use Yii's update:
$.fn.yiiGridView.update('bills-grid', {
type: 'GET',
url: <?php echo Yii::app()->createUrl('controller/action') ?>"?Class[attribute]=<?php echo $_GET['value'] ?>
success: function() {
$.fn.yiiGridView.update('bills-grid');
}
});
This is how i do it, just change the URL, it should be the same controller action of the gridview and change URL parameters to the structure represented in there, should be like Bills[attribute]=value.
