ZF 2.4 文件验证器需要 False 不起作用
ZF 2.4 File Validator Required False Doesn't Work
今天我更新到 ZF 2.4 以使用浮动验证器,但不幸的是我意识到我的文件上传表单字段给出了意外的错误消息。
这是我的表单对象
$this->add([
'name' => 'profileimage',
'type' => '\Zend\Form\Element\File',
'attributes' => [
'id' => 'profileimage',
'class' => 'styled',
],
]
);
这是我的验证器
$inputFilter->add([
'name' => 'profileimage',
'required' => false,
'allow_empty' => true,
'priority' => 300,
'filters' => [
['name' => 'StripTags'],
['name' => 'StringTrim'],
],
'validators' => [
[
'name' => '\Zend\Validator\File\IsImage',
],
[
'name' => '\Zend\Validator\File\UploadFile',
],
[
'name' => '\Zend\Validator\File\ImageSize',
'options' => [
'minWidth' => 300,
'minHeight' => 300,
]
],
[
'name' => '\Zend\Validator\File\Size',
'options' => [
'max' => '20MB',
]
],
]
]);
如您所见,图片上传字段不是必填字段,可能为空。但是在我的表格中我得到了这些错误:
array (size=1)
'profileimage' =>
array (size=4)
'fileIsImageNotReadable' => string 'File is not readable or does not exist' (length=38)
'fileUploadFileErrorNoFile' => string 'File was not uploaded' (length=21)
'fileImageSizeNotReadable' => string 'File is not readable or does not exist' (length=38)
'fileSizeNotFound' => string 'File is not readable or does not exist' (length=38)
我该如何处理这个问题?我需要这个字段是可选的。
更改过滤器
$inputFilter->add([
'name' => 'profileimage',
'type' => '\Zend\InputFilter\FileInput',
'required' => false,
'allow_empty' => true,
'priority' => 300,
'filters' => [
['name' => 'StripTags'],
['name' => 'StringTrim'],
],
'validators' => [
[
'name' => '\Zend\Validator\File\IsImage',
],
[
'name' => '\Zend\Validator\File\UploadFile',
],
[
'name' => '\Zend\Validator\File\ImageSize',
'options' => [
'minWidth' => 300,
'minHeight' => 300,
]
],
[
'name' => '\Zend\Validator\File\Size',
'options' => [
'max' => '20MB',
]
],
]
]);
