As suggested by yii2-social I added the g+ share buttons using GooglePlugin widget
<?php echo GooglePlugin::widget(['type'=>GooglePlugin::SHARE, 'settings' => []]); ?>
And also set the required values at social module configuration level as below
'social' => [
// the module class
'class' => 'kartik\social\Module',
// the global settings for the facebook plugins widget
'google' => [
'pageId' => 'my_value',
'clientId' => 'my_value',
],
],
When I click on share button I am redirected to google plus share window where I can type message (& share with public/group etc) but when I click share nothing is happening. Not sure where I am going wrong. No error is getting displayed too. Please help.
