USAGE

The view

You must have inputs to your values will be appended in the grid and references in the DynamicGridForm through the input id. Replace the "multipleModels" by your array of objects that contains the values and "modelClass" by a string that refence your model. Each column corresponds to an entry and must contain the attribute in the model that this column references. The following code renders the DynamicGridForm used in preview.

The controller

At the controller, you will receive the values attached to the grid when submitting the form. The values will be in the following format:

<?php
 [
            'Telephone' => [
                0 => [
                    'ddi' => '55',
                    'ddd' => '61',
                    'number' => '999999999',
                    'type' => 'Cel'
                ],
                1 => [
                    0 => [
                        'ddi' => '55',
                        'ddd' => '62',
                        'number' => '88888888',
                        'type' => 'Tel'
                    ],
                ]
            ]
        ];
?>

Then with the following code you can save the data.

SETTINGS

The widget supports all parameters that one would pass for any Yii Input Widget. The additional parameter settings specially available for the DynamicGridForm widget configuration are:

columns: An array with column settings. Currently, we have two settings for columns: NormalColumn and ActionColumn. For NormalColumn the parameters accept are:

headerOptions: An array with the options of header. You can see the options allowed here.
options: An array with the options of content. You can see the options allowed here.
id: A string that reference an input id. Since of v1.2.0 this param is optional and you can have a column without referenced input
attribute: A string that referece an attribute of the model informed. This param is required
value: An string or clousure that will return the value of input hidden when the widget is rendered. When clousure is informed then the signature must be:

<?php

      [
          'id' => 'telephone-ddi',

JAVASCRIPT MANIPULATIONS

Since of v1.5.0 you can access the instance of class that represents the DynamicGridForm (js) through the following code.

window[$("#tableId").attr('data-object')]

If you informed the property "variableJsName" you can access directly with the name specified in the variable.

window['{stringInformedInThevariableJsName}']

You can get the all values inserted in the grid with the follow code:

await window[$("#tableId").attr('data-object')].getAllDataTable()
