是否有办法检查验证器是否因 unique 规则而失败？
$rules = array(
'email_address' => 'required|email|unique:users,email',
'postal_code' => 'required|alpha_num',
);
$messages = array(
'required' => 'The :attribute field is required',
'email' => 'The :attribute field is required',
'alpha_num' => 'The :attribute field must only be letters and numbers (no spaces)'
);
$validator = Validator::make(Input::all(), $rules, $messages);
if ($validator->fails()) {
通俗地说，我基本上想知道:“验证失败是因为 email_address 不是唯一的吗？”
最佳答案
检查返回的失败规则数组中的特定规则
if ($validator->fails()) {
$failedRules = $validator->failed();
if(isset($failedRules['email_address']['Unique'])) {
...
关于php - Laravel 验证 : check why validator failed，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25573617/
