I copied and pasted your code in one of my views. I just changed your model so I am using one of my models (tables). Your code works perfectly in my view. So I think you should check if the problem is one of these:
You are not correctly importing one of these:
use backend\models\Developers;
use yii\jui\AutoComplete;
use yii\web\JsExpression;
Your table Developers is empty
In the part of your code that says:
->select(['name as value', 'name as label','developer_id as id'])
Are you sure your table developer has the columns name and developer_id?

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 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 learned here how one can save the data to the fields of join table CoursesMemberships while adding or editing a student in CakePHP 3.x. In order to add grades for many courses I can do this in my add and edit forms:
echo $this->Form->control('courses.0.id', ['type' => 'select', 'options' => $courses]);
echo $this->Form->control('courses.0._joinData.grade');
echo $this->Form->control('courses.1.id', ['type' => 'select', 'options' => $courses]);
echo $this->Form->control('courses.1._joinData.grade');
echo $this->Form->control('courses.2.id', ['type' => 'select', 'options' => $courses]);
echo $this->Form->control('courses.2._joinData.grade');
...
but this form:
has a fixed number of courses for each student;
requires to select the course id from the list ('type' => 'select');
adds all courses to the student record even if not attended (well, the corresponding grade field can be kept empty, but still).
Is there a way to have a simpler form, where all courses are listed and one can only checkbox the course attended and enter the corresponding grade? I found it very challenging using control...
EDIT:
After #ndm suggested a very nice method below, I implemented it in the add.ctp:
foreach ($courses as $key => $course) {
echo $this->Form->control('courses.'.$key.'.id', ['type' => 'checkbox', 'hiddenField' => false, 'value' => $key,
'label' => $key]);
echo $this->Form->control('courses.'.$key.'._joinData.grades');
}
and corrected StudentsTable.php accordingly. And it runs with no problems.
However, if I do the same in edit.ctp, the previously saved records (e.g. for 1, 3, 5 and 7 courses are now listed as 1, 2 and 3 showing the grades for former 3rd 5th and 7th courses and the form forces me to check those three boxes. I understand that the first record disappeared because my courses start with id=1 (and so does the $key in the loop) and 'courses.0.id' is thus missing, but the general problem is that the empty fields removed by beforeMarshal function are no longer recognized in edit.ctp form and I cannot find a reasonable way to edit the student's record.
There is no build in support for what you are trying to achieve, you'll have to come up with a custom solution, which will likely either require a mixture of form and marshalling logic, or JavaScript.
You could create for example a list of checkboxes, and use the id value (wich will be zero in case the checkbox isn't checked, or the ID in case it is checked) to remove unchecked entries from the submitted data before marshalling, something like this:
echo $this->Form->control('courses.0.id', [
'type' => 'checkbox',
'value' => $courses[0]->id,
'label' => $courses[0]->title
]);
echo $this->Form->control('courses.0._joinData.grade');
echo $this->Form->control('courses.1.id', [
'type' => 'checkbox',
'value' => $courses[1]->id,
'label' => $courses[1]->title
]);
echo $this->Form->control('courses.1._joinData.grade');
// ...
// in the `StudentsTable` class
public function beforeMarshal(\Cake\Event\Event $event, \ArrayObject $data, \ArrayObject $options)
{
forach ($data['courses'] as $key => $course) {
if (empty($course['id'])) {
unset($data['courses'][$key])
}
}
}
Alternatively you could use JavaScript to disable the controls related to the checkbox so that they aren't being submitted in the first place. For this to work properly you'll need to make sure that you disable the hidden field that is by default being generated for checkboxes (see the hiddenField option), as otherwise zero will be sent for unchecked checkboxes.
Here's a quick, untested jQuery example to illustrate the principle:
echo $this->Form->control('courses.0.id', [
'class' => 'course-checkbox',
'data-join-data-input' => '#course-join-data-0',
'type' => 'checkbox',
'hiddenField' => false, // no fallback, unchecked boxes aren't being submitted
'value' => $courses[0]->id,
'label' => $courses[0]->title
]);
echo $this->Form->control('courses.0._joinData.grade', [
'id' => 'course-join-data-0',
'disabled' => true
]);
// ...
$('.course-checkbox').each(function () {
var $checkbox = $(this);
var $joinDataInput = $($checkbox.data('join-data-input'));
$checkbox.on('change', function () {
$joinDataInput.prop('disabled', !$checkbox.prop('checked'));
});
});

I have a dataprovider to search a world but my listview does not display any record? How can i send this query object to listview?
every thing in my webpage is worked very good but at the output my list view show "not found any result" this mean my list view code is no have problem . problem is in my dataprovider and this query beacuse i customize that
my controller:
$query = new Query();
$dataProvidersearch=new ActiveDataProvider([
'query'=>$query->from('tbl_post')->Where(['like', 'title', $search])-
>andWhere(['like', 'en_title', $search])->andWhere(['like', 'content', $search])->andWhere(['like', 'en_content', $search]),
]);
this is my list view in my view:
$posts = $model->getModels();
echo ListView::widget([
'dataProvider'=>$posts,
'itemView'=>'search',
'summary' => '',
'itemOptions' => [
'tag' => false
],
]);
I'm not sure you have enough code here for someone to help. Even something simple like a listview could consist of a view, a controller, and two model files and your code could be failing at any of these points. You may have simply forgot to include the listview library at the top of your view, but we can't see that in your current example.
What I would recommend is using Gii to generate a listview. It is simple to do and once you have it created, you can study the code to see where you went wrong. You can see how to get started generating code with Gii here: http://www.yiiframework.com/doc-2.0/guide-start-gii.html
ANSWER FROM COMMENTS: Replace andWhere with orWhere, no results are found because no record can match 'title' and 'en_title' and 'content' and 'en_content'.
You are submitting $posts as 'dataProvider' while it should be dataProvidersearch
Instead of:
$posts = $model->getModels();
echo ListView::widget([
'dataProvider'=>$posts,
'itemView'=>'search',
'summary' => '',
'itemOptions' => [
'tag' => false
],
];
Should be:
$posts = $model->getModels();
echo ListView::widget([
'dataProvider'=>$dataProvidersearch,
'itemView'=>'search',
'summary' => '',
'itemOptions' => [
'tag' => false
],
];
I can upload files with special field upload_multiply and then save their names in DB, but how to print them back when editing the record? I use one-to-many relation, database structure like objects and objects_images, where exist object_id, name and url of uploaded image. Im using Laravel 5.4.
Now my code is very typicall:
I have a ObjectCrudController where i build form for my project. I use buildt-in Backpack/CRUD fields like this (for categories):
$this->crud->addField([
'label' => 'Category to display',
'type' => 'select',
'name' => 'category_id',
'entity' => 'category',
'attribute' => 'name',
'model' => 'App\Models\Category',
'wrapperAttributes' => [
'class' => 'form-group col-md-4'
]
]);
But I cant understand how to upload some images and then display their records as miniatures, also i need an ability to remove already uploaded image record. I think there can be used something like html field or view from backpack CRUD, but i don't know where to start.
