POST working wierdly in yii2 - post

Question

Below given is the code for my view
<div class="col-md-6">
<?php
if($fanclub_count<2)
{?>
<?php $form = ActiveForm::begin();?>
<?= $form->field($model_fanclub, 'crew_member_id')->dropDownList(ArrayHelper::map(MovieCrewMembers::find()->all(),
'id', 'name'),['prompt'=>'Select Crew','style'=>'width:50%']) ?>
<?= Html::submitButton(Yii::t('app', 'Join'),
['class' =>'btn btn-success']) ?>
<?php ActiveForm::end();
}?>
</div>
<div class="col-md-6">
<?php
if($user_clubs!=null)
{
foreach($user_clubs as $active_clubs )
{
$image= '/movie_crew_members/' . $active_clubs[0]."_".$active_clubs[2];
$path = \Yii::$app->thumbler->resize($image,55,55,Thumbler::METHOD_NOT_BOXED,true);
?>
<div class="col-md-6">
<img src="cache/<?php echo $path?>"></br>
<a href="<?php echo \Yii::$app->getUrlManager()->createUrl( [ '/users/change_fanclub',
'id'=>$active_clubs[0],'userid'=>$user_id] ); ?>">
<i class="fa fa-times-circle-o fa-2x"></i></a>
</div>
<?php
}
}
else
{
echo "No Active Clubs";
}
?>
</div>
there are basically two things a dropdown box and a image with a icon which redirect to a action. Sometimes it works perfect sometimes not. ie,when i click the drop down it gets redirected to users/change_fanclub. how is it possible? dropdown is independent of action users/change_fanclub. then how come it get redirected there?

Answer 1

I solved the problem by using this
<?php
$form = ActiveForm::begin( [
'method' => 'post',
'action' => [ "users/profile","user_id"=>$user_id ],
] );
?>
i don't know why i got redirected to users/change_fanclub when i click on the submit button of model_fanclub instead of going to users/profile. But i removed the error by specifying the action in ActiveForm.
