How to show form errorSummary() in red?

Question

I have this form:

<?php 
   $form = $this->beginWidget('CActiveForm', array(
            'id' => 'login-form',
            'enableClientValidation' => true,
            'clientOptions' => array(
                'validateOnSubmit' => true,
            ),
        ));


    $errorMsg = $form->errorSummary($userModel, "", "");

    if(!empty($errorMsg))
    {
        echo '<div class="alert alert-danger" style="text-align:center; width:800px; margin:auto;">' . $errorMsg . '</div>';
         echo '<br>';
     }

    $form->labelEx($userModel, 'email');
    echo $form->textField($userModel, 'email');
    $form->error($userModel, 'email');
?>

I am trying to print the error message when the email is invalid, but I want to print it using the red background from bootstrap. The problem is that without any errors it still shows the red bar.

It seems that this happens because errorSummary() is never really null

you mean **$errorMsg** instead of errorSummery() or? post a var_dump($errorMsg) — donald123, Jul 08 '15 at 06:57
`$errorMsg = errorSummary()` . But the var dump prints `NULL`. — J_Strauton, Jul 08 '15 at 07:00
Use *isset($errorMsg)* in the if condition. You can find the answer here *http://stackoverflow.com/questions/5615747/what-is-the-difference-between-null-and-empty* — ash__939, Jul 08 '15 at 07:09

Thats not how things work with the summary.

The errorSummary()-function always returns content to be added to the page.
The function makes sure the returned div is marked as hidden if there are no errors.

The reason it is done like that is so that the summary is there for front-end validation as well. The javascript will update and hide/show the div when needed.

So basically you should do this:

echo $form->errorSummary($userModel, "", "", array('class' => "alert alert-danger"));

And get rid of the extra if(!empty($errorMsg)) ...

Yup, that works. I just found it here: http://stackoverflow.com/questions/20718652/how-can-i-add-class-to-errorsummay-without-remove-header-message — J_Strauton, Jul 08 '15 at 07:12

You can change class like this:

<?= $form->errorSummary($model, ['class' => 'alert alert-danger']); ?>
