在Symfony上使用ElFinder：我无法选择图像

Question

我想在Symfony项目中使用ElFinder作为我的文件管理器。我在GitHub上关注了文档。在我的路线上。yaml:

elfinder:
resource: '@FMElfinderBundle/Resources/config/routing.yaml'

security.yaml

- { path: ^/efconnect, role: [ROLE_USER] }
- { path: ^/elfinder, role: [ROLE_USER] }

最后在fm_elfinder.yaml 上

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

然后我在Sonata的Admin元素中添加了它，如下所示：受保护的函数配置FormFields(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();
}

然后我进入Sonata Admin，当我尝试添加图像时，打开一个窗口，我添加了一个jpeg，但当我点击它时，似乎什么都没有发生。比如，我可以选择它，但我的窗口保持打开状态，并且我的字段不会填充图像的名称。谢谢你的帮助。

好的，我可以处理我的easyadmin表单了。这是easyAdmin 2配置：

easy_admin:
entities:
BlogPost:
class: AppEntityBlogPost
form:
fields:
- { property: 'title', label: 'page.title' }
- { property: 'image', type: 'AppFormElFinderType', label: 'blog.image.file', type_options: { enable: true, instance: 'single' } }

(我将vendor/helios-ag/fm-elfinder-bundle/src/Form/Type/ElFinderType.php文件复制到了AppFormElFinderType.php。这不是必需的(。

我将fm_elfinder连接器设置为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

接下来，我将捆绑包中的两个模板文件复制到我的templatesbundles目录：

{# 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 %}

第一个包含字段和填充它们所需的JavaScript。我添加了一个Add按钮。这将打开elfinder，一旦选择图像，该按钮将被隐藏，并将添加一个Remove按钮。

接下来是ElFinder窗口：

{# templates/bundles/FMElfinderBundle/Elfinder/simple.html.twig #}

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

}
},
// 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;
});
}
},
managers: {
// 'DOM Element ID': { /* elFinder options of this DOM Element */ }
'elfinder': {}
}
});
</script>
</head>
<body>
<!-- Element where elFinder will be created (REQUIRED) -->
<div id="elfinder"></div>
</body>
</html>

这里添加的主要功能是getFileCallback功能：

getFileCallback: function (file) {
window.opener.setValue(file.url);
window.opener.displayImage(file.url);
window.close();
},

这现在适用于我的单个图像字段，并且不会影响CKEditor集成。
