我想使用laravel 5从请求表更新用户表 请建议如何轻松完成。我有两个表数据，并希望根据请求表数据更新用户表，其中请求表有外国sm_id和用户表有主要ID请建议
提前致谢
请求数据：
Array (
[0] => Array ( [id] => 1 [sm_id] => 1 [field_name] => first_name [value] => G2 [created_at] => 2017-02-27 14:17:35 [updated_at] => 2017-02-24 11:05:03 [deleted_at] => )
[1] => Array ( [id] => 2 [sm_id] => 4 [field_name] => phone [value] => 123467890 [created_at] => 2017-02-27 16:55:48 [updated_at] => 2017-02-27 11:02:27 [deleted_at] => )
[2] => Array ( [id] => 3 [sm_id] => 4 [field_name] => first_name [value] => John [created_at] => 2017-02-27 16:55:48 [updated_at] => 2017-02-27 11:02:27 [deleted_at] => )
[3] => Array ( [id] => 4 [sm_id] => 4 [field_name] => last_name [value] => Hunny [created_at] => 2017-02-27 16:55:48 [updated_at] => 2017-02-27 11:02:27 [deleted_at] => ) )
User Data:
Array
(
[id] => 4
[social_id] =>
[role_id] => 0
[name] =>
[first_name] => max
[last_name] => rony
[gender] => male
[dob] => 02-02-2017
[language] => english
[location] => USA
[address] => ABCD
[email] => max.jrny@jioc.com
[phone] => 7894561230
[id_proof] =>
[id_proof_path] =>
[remember_token] =>
[provider] => website
[biography] => Here is about
[approve] => 1
[created_at] => 2017-02-22 12:16:56
[updated_at] => 2017-02-22 12:16:56
[deleted_at] =>
)
Expected result in user table
Array
(
[id] => 4
[social_id] =>
[role_id] => 0
[name] =>
[first_name] => john
[last_name] => Hunny
[gender] => male
[dob] => 02-02-2017
[language] => english
[location] => USA
[address] => ABCD
[email] => max.jrny@jioc.com
[phone] => 123467890
[id_proof] =>
[id_proof_path] =>
[remember_token] =>
[provider] => website
[biography] => Here is about
[approve] => 1
[created_at] => 2017-02-22 12:16:56
[updated_at] => 2017-02-22 12:16:56
[deleted_at] =>
)
Here is my code
public function verifyInformation($id){
if($id){
$getRequest = request::all()->toArray();
$user = User::where('id', $id)->first()->toArray();
foreach($getRequest as $row=>$value){
foreach($value as $rowKey => $result){
$array_key = array_keys($user);
$arrayDiff = array_diff($value, $user);
$find = $arrayDiff['field_name'];
if(in_array($find, $array_key)){
foreach($array_key as $k => $v){
if($v == $find){
$fieldKey = $v;
$fieldValue = $arrayDiff['value'];
if($fieldValue){
$user = new User;
$user->$fieldKey = $fieldValue;
$user->save();
return redirect()->back()->with("status", "Well done!! profile updated successfully");
}
}
}
}
}
}
}
}
注意：仅在预期结果中更新了phone，first_name和last_name

此代码将提供更新的数组以保存并指示是否有任何值已更改。只需要设置四个声明，然后是一个包含条件语句的foreach循环，该语句命令将数据推送到数组中。修改我的代码段以适合您的目的。
