Yii: run a function when a submitButton is pressed - php

Question

I'm very new to Yii, and trying to understand an existing web app, so please bear with me.
I've been having issues with a certain function, that seems to fail retaining data whenever actionView is calledhere, but I thought perhaps I was going about this problem all wrong.
Instead, I thought perhaps the button could directly run the function from the controller, instead of... whatever it was doing prior.
I looked at a sample here that had this:
<?php echo CHtml::submitButton('CSV Report', array('submit'=>'getReport')); ?>
Where getReport is the function in my controller (actionGetReport).
Unfortunately, it's not working. Here's the code of my _commentform.php:
<?php $post = $forum; ?>
<?php $comment = $model; ?>
<div id="comment_form<?=$post->id?>" class="other-member-comment-box">
<?php
$user=Persons::model()->findByAttributes(array('party_id'=>Yii::app()->user->id));
$country=Lookup_codes::model()->findByAttributes(array('id'=>$user->country));
$location = empty($country) ? '' : 'from '.$country->name;
?>
<div class="user-profilepic">
<a href="<?php echo Yii::app()->createUrl('persons/view/id/'.$user->showViewLinkId())?>"><img src="<?php
if(!empty($user->image) AND file_exists( Yii::getPathOfAlias('webroot').'/images/profile_picture/'.$user->party_id . $user->image)){
echo Yii::app()->request->baseUrl.'/images/profile_picture/'.$user->party_id . $user->image;
} else echo Yii::app()->request->baseUrl.'/images/profile_picture/NA.jpg';
?>"></a>
</div>
<div class="form">
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'comment-form',
'action'=>Yii::app()->createUrl('forum/view/id/'.$forum->id),
'enableAjaxValidation'=>false,
)); ?>
<?php echo $form->errorSummary($model); ?>
<div class="row">
<?php echo $form->hiddenField($model,'node_type_id',array('value'=>'7')); ?>
<?php echo $form->error($model,'node_type'); ?>
</div>
<div class="row">
<?php echo $form->hiddenField($model,'content_id',array('value'=>$forum->id)); ?>
<?php echo $form->error($model,'content_id'); ?>
</div>
<div class="row">
<?php echo $form->hiddenField($model,'category',array('value'=>$forum->category)); ?>
<?php echo $form->error($model,'category'); ?>
</div>
<div class="row">
<?php echo $form->textArea($model,'content',array('rows'=>6, 'cols'=>90),array('id'=>'sample')); ?>
<?php echo $form->error($model,'content'); ?>
</div>
<input type="hidden" value="<?php echo $view; ?>" id="view" name="view"/>
<div class="row buttons">
<?php
if ($view == 'view'){
if ($model->isNewRecord) {
echo CHtml::submitButton('Reply', array('id'=>'comment'.$comment->id));
} else {
echo CHtml::button('Save', array('submit'=>'updatecomment'));
}
}?>
</div>
<?php $this->endWidget(); ?>
</div><!-- form -->
</div>
And here's the UpdateComment function from my controller:
public function actionUpdateComment()
{
Yii::log(CVarDumper::dumpAsString("ForumController: Update COMMENT!"));
Yii::log(CVarDumper::dumpAsString($_POST['Comment']));
exit();
}
I'm not exactly sure what I'll get by the $_POST['Comment'], but if the code worked, I'd very least expect it to log out the "ForumController: Update COMMENT!". It doesn't.
I tried changing the submitButton to button, but that just kills the button function entirely.
Next, I tried this answer here.
So I changed the submitButton code to this:
echo CHtml::submitButton($model->isNewRecord ? 'Reply' : 'Save',array('id'=>'comment'.$comment->id));
And added this to the end:
<script>
$(document).ready(function() {
$('#text_form_submit').click(function(ev) {
ev.preventDefault();
$.ajax({ type: 'POST', dataType: 'JSON',
url: '<?php echo Yii::app()->createUrl("forum/UpdateComment"); ?>',
success:function(data){
if(data !== null) {
$('#Text_group').val(data);
$('#text-form').submit();
}
},
error: function() {
alert("Error occured!!!.");
},
});
return false;
});
});
</script>
Not exactly sure what the code does, other than call a function as well, but as well, it doesn't work (I also changed POST from GET and back).
Any suggestions? I feel like CActiveForm is to blame here, but even modifying that causes the site to fail in loading pages.

You have a long question and could be you should split your question in more question with simple question each ..
A firts answer the submit button don't contain the target function see this doc
http://www.yiiframework.com/doc/api/1.1/CHtml#submitButton-detail
the target function (php controller/action) is defined in form .. this is from html .. is the form definition that define the target for the submitted data ..
if you want execute the actionGetReport you should define the target in form action
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'comment-form',
'action'=>Yii::app()->createUrl('yourController/actionGetReport'),
'enableAjaxValidation'=>false,
)); ?>
