每当页面通过重定向/渲染/刷新加载或重新加载时，它似乎会自动提交最后提交给数据库的信息。我尝试向 add 方法添加限制，但它似乎保存了上一次提交的信息，这允许它绕过 isset $_POST。
包含 actionform 的视图。
<div class="form offset2">
<?php $form = $this->beginWidget('bootstrap.widgets.TbActiveForm', array(
'id'=>'userTeam-form',
'enableAjaxValidation'=>false,
// Check thta the action method below is correct
'action'=> array('/User/AddTeamMessage', 'id' => $model->id),
)); ?>
<!--
Would allow user to access specific team messages and control how much gets display.
still under construction.
-->
<div class="row">
<?php
echo CHtml::dropDownList("teamId", 'id', Chtml::listData($model->memberOfTeams, 'id', 'teamName'),array(
'empty'=>'Select Team',
'ajax'=>array(
'type'=>'POST', // request type
'url'=>CController::createUrl('DisplayMessage'),
'update'=>'#teamMessages', // selector to update
'data'=>array('teamId'=>'js:this.value'),
)
)
);
echo CHtml::dropDownList("teamMessages", '', array(), array('prompt'=>'Select Messages'));
?>
</div>
<!--
Only works for coaches
Allows coaches to submit team messages.
-->
<?php if ($model->isCoach()) { ?>
<!-- Text area for the coach to enter messages in -->
<textarea name="addTeamMessage" class="span5" rows="5" style="resize: none;"></textarea>
<!-- submit button -->
<?php echo CHtml::submitButton('Submit Message', array(
'class' => 'btn btn-primary',
'name' => 'submitTeamMessage'
)); ?>
<?php } ?>
<!-- end the widget. everything will be send to UserController/AddTeamMessages -->
<?php $this->endWidget(); ?>
当活动表单被触发时的控制器。
/* add a team message submitted by the coach of the team */
public function actionAddTeamMessage($id)
{
/* check if team and message aren't null */
if(isset($_POST['submitTeamMessage']))
{
if(isset($_POST['teamId']['addTeamMessage']))
{
try
{
/* creates a new message */
$teamModel = new TeamMessage;
$teamModel->teamId = $_POST['teamId'];
$teamModel->content = $_POST['addTeamMessage'];
$teamModel->sendTime = new CDbExpression('NOW()');
$teamModel->save();
}
catch(Exception $e)
{
echo "Unable to save.";
}
}
}
/* render the profile page for the current user */
$user=User::model()->findByPk($id);
$this->render('profile', array(
'model' => $user));
}
