我需要验证公司名称和电子邮件，以避免重复输入。这是我到目前为止所得到的
public function rules()
{
$businesses = Business::all();
foreach ($businesses as $business) {
return [
'name' => 'unique:businesses,name,' . $business->id,
'email' => 'email|unique:businesses,email,' . $business->id,
'logo' => 'file|size:5000,' . $business->id,
'banner' => 'file|size:5000,' . $business->id,
];
}
}
但它仍然返回此错误
SQLSTATE [23000]：违反完整性约束：1062复制条目
尝试这个 ：
public function rules()
{
return [
'name' => 'unique:businesses,name,' . $business->id,
'email' => 'email|unique:businesses,email,' . $business->id,
'logo' => 'file|size:5000,' . $business->id,
'banner' => 'file|size:5000,' . $business->id,
];
}
例如：'name'=>'unique：businesses，name，'。$ business-> id，
说明：这businesses是表，其中字段为name，期望id=$business->id
