<table width="960px" align="center">
<tr>
<td rowspan="3" width="404"><label id="lbbanner"><b>UIT SOCIAL NETWORK</b></label></td>

</tr>
<tr>

<input type="button" value="Log in" id="btnLogin" name="Login"/></td>
<td colspan="2" align="right"></td>
</tr>
<tr>
</tr>
</table>
</form>
In SiteController I have actionHomePage()
public function actionHomePage() {
$model = new LoginForm();
$model->username = $_POST['usernamelogin'];
$model->password = $_POST['passwordlogin'];
$model->rememberMe = $_POST['rememberlogin'];
//echo $model->errors;
print_rcount(($model->getErrors()));
//echo $model->username . "&&" . $model->password . "$$" .$model->rememberMe;
// validate user input and redirect to the previous page if valid
if ($model->validate() && $model->login()) {
$this->loginStatus = true;
//$this->redirect(Yii::app()->user->returnUrl);
echo "SUCCESS";
} else {
echo "Error";
}
}
When I fill username and password with correct info but it return "ERROR"
$model->validate() is false but I have correct info.
I dont know what i am wrong in this part.

Answer 1

Your input variable names need to match the POST variables you are querying so
<td><input type="text" witdth="200px" id ="usernamelogin" name="txtUsernameLogin" /></td>
<td><input type="password" width="200px" id="passwordlogin" name="txtPasswordLogin" /></td>
should be like this:
<td><input type="text" witdth="200px" id ="usernamelogin" name="usernameLogin" /></td>
<td><input type="password" width="200px" id="passwordlogin" name="passwordLogin" /></td>
same for rememberlogin

Answer 2

because in actionHomePage() : $model->rememberMe = true or false; $_post return a string . You try :
($_POST['rememberlogin'] == "false") ? $model->rememberMe = false : $model->rememberMe = true ;
