PHP 7 Zend Framework 2.4 InputFilter

Question

请帮助解决以下错误。我正在关注Zend Framework documentation。

致命错误：

Cannot use 'Int' as class name as it is reserved in E:\Working\PHP\Zend-Framework\Zend-Framework-2\zf2-stable\vendor\zendframework\zendframework\library\Zend\Filter\Int.php on line 12

错误：

array('name' => 'Int'), ## Fatal error
array('name' => 'ToInt') ## Zend\Filter\FilterPluginManager::get was unable to fetch or create an instance for Zend\Filter\ToInt
array('name' => 'StringTrim') ## Works Only for Edit and Delete, however Not for Add

环境：

ZF2教程/模块/专辑/视图/专辑/专辑/ add.phtml

<?php

// module/Album/view/album/album/add.phtml:

$title = 'Add new album';
$this->headTitle($title);
?>
<h1><?php echo $this->escapeHtml($title); ?></h1>
<?php
$form->setAttribute('action', $this->url('album', array('action' => 'add')));
$form->prepare();

echo $this->form()->openTag($form);
echo $this->formHidden($form->get('id'));
echo $this->formRow($form->get('title'));
echo $this->formRow($form->get('artist'));
echo $this->formSubmit($form->get('submit'));
echo $this->form()->closeTag();

修改

在公共函数中注释掉以下行getInputFilter（）可以工作：

        /*
        $inputFilter->add(array(
            'name'     => 'id',
            'required' => true,
            'filters'  => array(
                array('name' => 'Int'),
            ),
        ));
        */

感谢。

Answer 1

我很确定你应该在这个版本中使用IsInt过滤器而不是Int过滤器。

Zend\I18n\Validator\IsInt

Answer 2

我使用"zendframework/zendframework": "2.3.9",

1）创建类 ToInt.php

<?php
namespace Application\Filter;

use Zend\Filter\AbstractFilter;

class ToInt extends AbstractFilter
{
    /**
     * Returns (int) $value
     *
     * If the value provided is non-scalar, the value will remain unfiltered
     *
     * @param  string $value
     * @return ToInt|mixed
     */
    public function filter($value)
    {
        if (!is_scalar($value)) {
            return $value;
        }
        $value = (string) $value;

        return (int) $value;
    }
}

2）输入

$inputFilter->add($factory->createInput(array(
    'name' => 'id',
    'required' => true,
    'filters' => array(
        array('name' => '\Application\Filter\ToInt'),
    ),
)));
