Join table and display - mysql

Question

I am using the Yii PHP framework, trying to display user_comment and user_reply from two tables who both have a column named comment_id.
This is the comment table
CREATE TABLE `comment` (
`comment_id` int(11) NOT NULL,
`byy` varchar(30) NOT NULL,
`user_comment` varchar(900) NOT NULL,
`topic_id` varchar(30) NOT NULL,
`created` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
`up` bigint(11) NOT NULL,
`down` bigint(11) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
This is the reply table
CREATE TABLE `reply` (
`reply_id` int(11) NOT NULL,
`comment_id` int(19) NOT NULL,
`byy` varchar(29) NOT NULL,
`user_reply` varchar(29) NOT NULL,
`created` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
`up` varchar(29) NOT NULL,
`down` varchar(29) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
I want to display user_comment and user_reply in a list view format, sorted according to the comment_id. I am having problems with that.
<?php
$querys = new Query;
$querys->select([
'comment.user_comment',
'reply.user_reply']
)
->from('comment')
->join('LEFT OUTER JOIN', 'reply',
'reply.comment_id =comment.comment_id') ;
$command = $querys->createCommand();
$data = $command->queryAll();
$queryd = new Query;
$queryd->select([
'comment.user_comment',
'reply.user_reply']
)
->from('comment')
->join('LEFT OUTER JOIN', 'reply',
'reply.comment_id =comment.comment_id')
->LIMIT(5);
$command = $queryd->createCommand();
$data = $command->queryAll();
foreach ($data as $detail) {
$dataArr[] = array(
'user_reply' => $detail['user_reply']
);
}
$dataProvider = new ArrayDataProvider([
'allModels' => $dataArr,
'pagination' => [
'pageSize' => 10,
],
'sort' => [
'attributes' => ['comment_created_at'],
],
]);
echo ListView::widget([
'dataProvider' => $dataProvider,
'itemOptions' => ['class' => 'comment-item'],
'itemView' => 'adapter',
]);
?>
Adapter class
<?php
use yii\helpers\Html;
use yii\helpers\HtmlPurifier;
//var_dump($model);exit;
?>
<div class="col-lg-12 col-sm-12">
<section>
<?php echo $model['user_reply']; ?>
</section>
</div>
I am getting this error:
Getting unknown property: Undefined index: user_reply
What am I doing wrong?

Try
foreach ($data as $detail) {
$dataArr[] = array(
'user_reply' => $detail['reply.user_reply']
);
}
or use alias
$queryd = new Query;
$queryd->select('comment.user_comment as user_comment,
reply.user_reply as user_reply')
->from('comment')
->join('LEFT OUTER JOIN', 'reply',
'reply.comment_id =comment.comment_id')
->LIMIT(5);
$command = $queryd->createCommand();
$data = $command->queryAll();
foreach ($data as $detail) {
$dataArr[] = array(
'user_reply' => $detail['user_reply']
);
}
and for dataProvider you must remeber there is a models collection then
<div class="col-lg-12 col-sm-12">
<section>
<?php
foreach($models as $model){
//echo $model['user_reply'];
echo $model->user_reply;
}
?>
</section>
</div>
