Question

我有以下验证规则：

'lightboard_line_1' => 'required_without_all:lightboard_line_2,lightboard_line_3|min:1|max:10',
'lightboard_line_2' => 'required_without_all:lightboard_line_1,lightboard_line_3|min:1|max:10',
'lightboard_line_3' => 'required_without_all:lightboard_line_1,lightboard_line_2|min:1|max:10',

因此，我们的想法是，当lightboard_line_2有值时，不再需要lightboard_line_1和lightboard_line_3。由于min和max规则，它们目前确实需要一个值。

有没有一种方法可以确保只有当字段有值且需要时才能确定最小值？

字段的HTML代码：

<input name="lightboard_line_1" type="text">
<input name="lightboard_line_2" type="text">
<input name="lightboard_line_3" type="text">

Answer 1

我会将验证规则更新为：

StopWatch

然后，在根据规则检查规则之前，我会根据完成的输入动态修改规则，例如：

$rules = [
  'lightboard_line_1' => 'required_without_all:lightboard_line_2,lightboard_line_3',
  'lightboard_line_2' => 'required_without_all:lightboard_line_1,lightboard_line_3',
  'lightboard_line_3' => 'required_without_all:lightboard_line_1,lightboard_line_2',
];

这样，if ( $request->has('lightboard_line_1') ) { // append to the rule $rules['lightboard_line_1'] .= '|min:1|max:10'; } else if ( ...和min仅对已完成的字段强制执行。随意根据需要优化代码。

Answer 2

我找到了一个解决方案，我现在正在验证使用此代码：

        /** @var Validator $validator */
        $validator = \Validator::make( $request->request->all(), [
            'lightboard_line_1' => 'required_without_all:lightboard_line_2,lightboard_line_3',
            'lightboard_line_2' => 'required_without_all:lightboard_line_1,lightboard_line_3',
            'lightboard_line_3' => 'required_without_all:lightboard_line_1,lightboard_line_2'
        ], [
            'required_without_all' => __( 'At least line is required' ),
            'min'                  => __( 'Your input should be at least :min characters' ),
            'max'                  => __( 'Your input cannot be more than :max characters' )
        ] );

        $validator->sometimes(
            'lightboard_line_1',
            'required|min:5|max:10',
            function ( $input ) {
                return ! empty( $input->lightboard_line_1 );
            }
        );
        $validator->sometimes(
            'lightboard_line_2',
            'required|min:5|max:10',
            function ( $input ) {
                return ! empty( $input->lightboard_line_2 );
            }
        );
        $validator->sometimes(
            'lightboard_line_3',
            'required|min:5|max:10',
            function ( $input ) {
                return ! empty( $input->lightboard_line_3 );
            }
        );

只有在需要字段时，Laravel 5.5验证最小长度
