[英]how to create an array element in form - zend framework 2
I want to create the following element : 我想创建以下元素:
<input type="file" name="file[]">
I have tried the following code in myproject/module/Member/src/Member/Form/EditForm.php : 我在myproject / module / Member / src / Member / Form / EditForm.php中尝试了以下代码:
$this->add(array(
'name' => 'file',
'type' => 'file',
'attributes' => array(
'class' => 'form-control col-md-7 col-xs-12',
'id' => 'file',
),'options' => array(
'multiple'=>TRUE
),
));
and 和
$this->add(array(
'name' => 'file[]',
'type' => 'file',
'attributes' => array(
'class' => 'form-control col-md-7 col-xs-12',
'id' => 'file',
),'options' => array(
'multiple'=>TRUE
),
));
but it is not working. 但它不起作用。
For file upload Zend Framework 2 has a special FileInput
class . 对于文件上传, Zend Framework 2具有一个特殊的
FileInput
类 。
It is important to use this class because it also does other important things like validation before filtering . 使用此类非常重要,因为它还会执行其他重要操作,例如在过滤之前进行验证 。 There are also special filters like the
File\\RenameUpload
that renames the upload for you. 还有一些特殊的过滤器,例如
File\\RenameUpload
,可以为您重命名上载。
Considering that $this
is your InputFilter
instance the code could look like this: 考虑到
$this
是您的InputFilter
实例,代码可能如下所示:
$this->add(array(
'name' => 'file',
'required' => true,
'allow_empty' => false,
'filters' => array(
array(
'name' => 'File\RenameUpload',
'options' => array(
'target' => 'upload',
'randomize' => true,
'overwrite' => true
)
)
),
'validators' => array(
array(
'name' => 'FileSize',
'options' => array(
'max' => 10 * 1024 * 1024 // 10MB
)
)
),
// IMPORTANT: this will make sure you get the `FileInput` class
'type' => 'Zend\InputFilter\FileInput'
);
To attach file element to a form: 要将文件元素附加到表单:
// File Input
$file = new Element\File('file');
$file->setLabel('My file upload')
->setAttribute('id', 'file');
$this->add($file);
