Question

我有2个字段来检查验证...

if(parent == 0)
     return 'tag is required';
else 
    return 'tag can be nullable';

我想要这样的事情：

'parent' => 'nullable|numeric',
'tags' => 'required_with:parent=0|array|max:8',

我尝试这样的事情，但这是错误的：

Answer 1

使用required_if规则。

如果anotherfield字段等于任何值，则验证字段必须存在且不为空。

'parent' => 'nullable|numeric',
'tags' => 'required_if:parent,0|array|max:8',
