A flexible possibility for InputErrorClasses (Ready for Bootstrap 4+)

[mano87]

Hello,
currently it is only possible with great effort to use the forms in combination with Bootstrap 4+. It would be good if you could use the InputErrorClass independently from the helper formRow.

Or is there a better way to implement the attached example? See the following code snippets...

/** @var Laminas\Form\View\Helper\FormElementErrors $helper */
$helper = $this->formElementErrors();
$helper->setMessageOpenFormat('<small class="invalid-feedback">');
$helper->setMessageCloseString('</small>');
$helper->setMessageSeparatorString('');

<div class="form-group row">
    <?php echo $this->formLabel($matriculationnumber); ?>
    <div class="col-sm-10">

        <?php if ($matriculationnumber->getMessages()) {
            $classAttributes = $matriculationnumber->hasAttribute('class') ? $matriculationnumber->getAttribute('class') . ' ' : '';
            $classAttributes = $classAttributes . 'is-invalid';
            $matriculationnumber->setAttribute('class', $classAttributes);
        } ?>

        <?php echo $this->formElement($matriculationnumber); ?>
        <?php echo $this->formElementErrors()->render($matriculationnumber); ?>
    </div>
</div>

@mano87 Until laminas-form supports this, I can recommend you @neilime's twbs-helper-module, which extends the helpers, changes the HTML accordingly and overrides the service manager's config to transparently use the extended helpers. That way, you will have all markup rendered according to Boostrap 4+.

…Boostrap 4+.

At the moment, version 5 is not yet supported: neilime/twbs-helper-module#165
But there is already a first pull request: neilime/twbs-helper-module#167

/** @var Laminas\Form\View\Helper\FormElementErrors $helper */
$helper = $this->formElementErrors();
$helper->setMessageOpenFormat('<small class="invalid-feedback">');
$helper->setMessageCloseString('</small>');
$helper->setMessageSeparatorString('');

You can use a factory for this. An example can be found in the forum.
