Having recently subscribed, I have come to seek assistance on a platform where I have previously found many solutions to my issues.
I have completed a course on Openclassrooms (Transitioning to a Professional PHP Architecture) which has equipped me with the necessary skills to work with Silex, Twig, and Bootstrap. As I delve into creating a website using Silex's documentation, there is a specific challenge I am facing with the FormBuilderInterface.
class ActivityType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('title', 'text')
->add('public', 'choice', array(
'choices' => array(
'children' => 'children',
'adults' => 'adults',
'family' => 'family',
),
))
->add('withHorses', 'choice', array(
'expanded' => 'true',
'label' => 'With horses',
))
->add('content', 'textarea')
->add('image', 'file', array(
'required' => 'false',
'data_class' => null,
));
}
public function getName()
{
return 'activity';
}
}
The data_class set to null is crucial to avoid an exception.
Below is the code snippet showcasing the form display:
{{ form_start(activityForm, { 'attr': {'class': 'form-horizontal'} }) }}
<div class="form-group">
{{ form_label(activityForm.title, null, { 'label_attr': {
'class': 'col-sm-4 control-label'
}}) }}
<div class="col-sm-6">
{{ form_errors(activityForm.title) }}
{{ form_widget(activityForm.title, { 'attr': {
'class': 'form-control'
}}) }}
</div>
</div>
<!-- Add more form field blocks as needed -->
{{ form_end(activityForm) }}
The file input appears in the form but check here for its current appearance.
Upon inspecting the DOM, an anomaly was observed here. The div housing the file input lacks the "form-group" class and attributes specified in the view (class: form-control and accept: images/*) are not being applied.
Despite extensive research and efforts, I have failed to resolve this issue related to Silex. Any guidance on positioning the file input between the text area and submit button, aligning the label and input horizontally, and incorporating view-specific classes and attributes would be greatly appreciated.
If anyone can shed light on the usage of data_class, particularly the necessity of setting it to null to prevent exceptions when dealing with file inputs through that interface, it would be highly valuable information.
Thank you in advance!
