Using ElFinder on Symfony: I can't select images - symfony

Question

I want to use ElFinder as my file manager in my Symfony project. I followed the doc on GitHub. In my routes.yaml:
elfinder:
resource: '#FMElfinderBundle/Resources/config/routing.yaml'
security.yaml
- { path: ^/efconnect, role: [ROLE_USER] }
- { path: ^/elfinder, role: [ROLE_USER] }
And finally on fm_elfinder.yaml
fm_elfinder:
instances:
default:
locale: '%locale%' # defaults to current request locale
editor: ckeditor # other options are tinymce, tinymce4, fm_tinymce, form, simple, custom
connector:
roots:
uploads:
driver: LocalFileSystem
path: uploads
upload_max_size: 2M
Then I added it on a Admin element on Sonata, like this:
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->with('Contenu')
->add('published', CheckboxType::class, ['required' => false, 'label' => 'Publier'])
->add('title', TextType::class, ['required' => true, 'label' => 'Titre'])
->add('textLink', TextType::class, ['required' => true, 'label' => 'Texte du lien'])
->add('media', ElFinderType::class, array(
'label' => 'Photo',
'enable' => true,
'required' => true,
'instance' => 'default',
'attr' => array('class' => 'form-control')
)
)
->end();
}
Then I go on Sonata Admin, and when I try to add an image, a window open, I added an jpeg but then when i click on it, nothing seems to happen. Like, I can select it but my window stay open and my field doesn't fill up with the name of the image.
Thanks for your help.

Ok I got it to work on my easyadmin forms. This is the easyAdmin 2 configuration :
easy_admin:
entities:
BlogPost:
class: App\Entity\BlogPost
form:
fields:
- { property: 'title', label: 'page.title' }
- { property: 'image', type: 'App\Form\ElFinderType', label: 'blog.image.file', type_options: { enable: true, instance: 'single' } }
(I copied the vendor/helios-ag/fm-elfinder-bundle/src/Form/Type/ElFinderType.php file to App\Form\ElFinderType.php. This is not required).
I set the fm_elfinder connector to simple :
# src/packages/fm_elfinder.yaml
fm_elfinder:
instances:
single:
locale: fr
editor: simple
theme: smoothness
relative_path: false
connector:
roots:
uploads:
driver: LocalFileSystem
path: uploads/images
show_hidden: false
upload_allow: [ 'image/png', 'image/jpg', 'image/jpeg' ]
upload_deny: [ 'all' ]
upload_max_size: 2M
Next I copied two of the template files from the bundle to my templates\bundles directory :
{# templates/bundles/FMElfinderBundle/Form/elfinder_widget.html.twig #}
{% block elfinder_widget %}
<div class="buttons">
<input type="button" {{ block('widget_attributes') }}
data-type="elfinder-remove-button" value="Delete" class="{% if value is empty %}hide{% endif %} remove-button"/>
<input type="button" {{ block('widget_attributes') }}
data-type="elfinder-add-button" value="Add" class="{% if value is not empty %}hide{% endif %} add-button"/>
</div>
{% if value is not empty %}
<img src="{{ value }}" alt="">
{% endif %}
<input type="text" {{ block('widget_attributes') }} {% if value is not empty %}value="{{ value }}" {% endif %}
data-type="elfinder-input-field" class="hide"/>
{% if enable and instance is defined %}
<script type="text/javascript" charset="utf-8">
const addButtonSelector = '[data-type="elfinder-add-button"][id="{{ id }}"]';
const removeButtonSelector = '[data-type="elfinder-remove-button"][id="{{ id }}"]';
const inputSelector = '[data-type="elfinder-input-field"][id="{{ id }}"]';
live('click', addButtonSelector, () => {
window.open("{{ path('elfinder', {'instance': instance, 'homeFolder': homeFolder }) }}?id={{ id }}", "popupWindow", "height=450, width=900");
});
removeButtonListener()
function live(eventType, elementQuerySelector, cb) {
document.addEventListener(eventType, function (event) {
const qs = document.querySelectorAll(elementQuerySelector);
if (qs) {
let el = event.target, index = -1;
while (el && ((index = Array.prototype.indexOf.call(qs, el)) === -1)) {
el = el.parentElement;
}
if (index > -1) {
cb.call(el, event);
}
}
})
}
function setValue(value) {
document.querySelector(inputSelector).value = value;
}
function displayImage(value) {
const inputElement = document.querySelector(inputSelector);
const parent = inputElement.parentElement
const image = document.createElement("img");
image.src = value;
parent.append(image)
const removeButton = document.querySelector(removeButtonSelector);
const addButton = document.querySelector(addButtonSelector);
removeButton.classList.remove('hide')
addButton.classList.add('hide')
removeButtonListener()
}
function removeButtonListener() {
const removeButtonElement = document.querySelector(removeButtonSelector);
if(removeButtonElement){
removeButtonElement.addEventListener('click', () => {
const addButtonElement = document.querySelector(addButtonSelector);
removeButtonElement.classList.remove('hide')
const parent = removeButtonElement.closest('.form-widget')
const inputElement = parent.querySelector('[data-type="elfinder-input-field"]');
inputElement.value = null
const imageElement = parent.getElementsByTagName('img')[0]
if (imageElement) {
parent.removeChild(imageElement)
}
removeButtonElement.classList.add('hide')
addButtonElement.classList.remove('hide')
document.querySelector(inputSelector).value = null;
})
}
}
</script>
{% endif %}
{% endblock %}
This first one contains the fields and the JavaScript needed to fill them in. I added a Add button. This will open the elfinder, once an image gets selected this button becomes hidden and a Remove button will be added.
Next is the ElFinder window :

function getUrlParam(paramName) {
const reParam = new RegExp('(?:[\?&]|&)' + paramName + '=([^&]+)', 'i');
const match = window.location.search.match(reParam);
return (match && match.length > 1) ? match[1] : '' ;
}

// bootCallback calls at before elFinder boot up
bootCallback: function (fm, extraObj) {
/* any bind functions etc. */
fm.bind('init', function () {
});
// for example set document.title dynamically.
var title = document.title;
fm.bind('open', function () {
var path = '',
cwd = fm.cwd();
if (cwd) {
path = fm.path(cwd.hash) || null;
}
document.title = path ? path + ':' + title : title;
}).bind('destroy', function () {
document.title = title;
});
}
},

}
});
</script>
</head>
<body>
<!-- Element where elFinder will be created (REQUIRED) -->
<div id="elfinder"></div>
</body>
</html>
The main thing added here to make it work is the getFileCallback function :
getFileCallback: function (file) {
window.opener.setValue(file.url);
window.opener.displayImage(file.url);
window.close();
},
This now works fine for my single image field and does not affect the CKEditor integration.
