Call to a member function format() on a non-object

[lestat1968]

Hi,

i've updated your extensions and framework to the latest version available with composer.

Now, in a update action i obtained the following error:

PHP Fatal Error – yii\base\ErrorException
Call to a member function format() on a non-object
in C:\wamp\www2\yii2basic\vendor\kartik-v\yii2-datecontrol\datecontrol\DateControl.php

in my view (_form.php):

    <?php

        // Use a DatePicker input with ActiveForm and model validation enabled.
        echo $form->field($model, 'data_nascita')->widget(DateControl::classname(), [
            'type'=>DateControl::FORMAT_DATE,
            'options'=>[
                'options' => ['placeholder' => 'Seleziona Data di nascita...',
                 ],
                'pluginOptions' => ['language' => 'it',
                                    'autoclose' => true,
                ],
            ],            
        ]);    

    ?>

in my config file (web.php):

...
   'components' => [
        'formatter' => [
            'class' => 'yii\base\Formatter',
            'dateFormat' => 'd/m/Y',
            'datetimeFormat' => 'd/m/Y H:i:s',
            'timeFormat' => 'H:i:s',            
        ],
...
    'modules' => [
        'datecontrol' => [
            'class' => 'kartik\datecontrol\Module',

            // format settings for displaying each date attribute
            'displaySettings' => [
                Module::FORMAT_DATE => 'd/m/Y',
                Module::FORMAT_TIME => 'H:i:s',
                Module::FORMAT_DATETIME => 'd/m/Y H:i:s',
            ],

            // format settings for saving each date attribute
            'saveSettings' => [
                Module::FORMAT_DATE => 'Y-m-d', // saves as unix timestamp
                Module::FORMAT_TIME => 'H:i:s',
                //Module::FORMAT_DATETIME => 'Y-m-d H:i:s',
                Module::FORMAT_DATETIME => 'U',
            ],

            // automatically use kartik\widgets for each of the above formats
            'autoWidget' => true,

        // other settings
        ],

where's the problem in my code?

It seems the DateControl extension was not properly updated by composer. Can you backup and purge your vendor folder in approot, and run php composer.phar install --prefer-dist and confirm.

[lestat1968]

I'll try..

[lestat1968]

i followed your instructions...

no success.. :-(

[kartik-v]

It seems there is a small glitch in datetime formatting. Will record this as a bug and provide a fix.

Fixed DateControl bug via this commit. Try to update via composer after 30 minutes.

thanks...

[lestat1968]

ok, Call to a member function format() issue is resolved, but now in update scenario widget don't display data value even if it is setted...

[kartik-v]

• What are your save and display values?
• What are your save and display formats?
• What is your widget configuration?

[lestat1968]

Thanks for your help Kartik,

since some of the settings of the framework and datecontrol class have changed since I wrote the code, I reread the documentation. If I can not find the problem I will ask again.

[lestat1968]

Ok, Kartik, issue resolved...

my mistake... data_nascita field was a datetime...
changed it to date and it works like a charm....

In the new widget version, I have set the display to be null (instead of showing the wrongly formatted value) - if the format is mismatched or violated. This will be useful for you to debug your formatting errors.
