我正确地接收了这两条消息，但我需要使用Laravel5加入这两个结果。
有人可以帮助我吗？或者是否有可能以其他形式这样做？
<?php
require_once 'includes/dbconnect.php';
session_start();
//require_once 'includes/dbconnect.php';
/* if (isset($_SESSION["username"]) && !empty($_SESSION["username"])){
echo "".strtoupper($_SESSION['username'])."(Sign out)"; }else{
echo "Sign In";
} */
if (isset($_POST["request"]))
{
//take care of injections
$service = mysqli_real_escape_string($link,$_POST['service']);
$service_details = mysqli_real_escape_string($link,$_POST['service_details']);
$duedate = mysqli_real_escape_string($link,$_POST['duedate']);
$postdate = mysqli_real_escape_string($link,$_POST['postdate']); //READ ONLY DATE POST
// Insert data into mysql + LOGGED IN USERS USERNAME TO BE INSERTED
$sql = "INSERT INTO serviceposts VALUES ('".$_SESSION["username"]."','".$service."', '".$service_details."', '".$duedate."', '".$postdate."')";
$result= $link -> query($sql) or die (mysqli_error($link));
echo "($result)";
// if successfully insert data into database, displays message "Successful".
if($result){
echo "request post success!";
echo'<script>window.location="http://localhost/Project2/User.php#viewrequests";</script>';
// header('Location: ../User.php?success=1');
}
else {
echo "Possible data input error";
//header('Location: ../user.php?error=1');
}
$link->close();
}
?>

更新
MessageUser
$mensajes = Messageuser::find(1)->conversaciones()->get();
$mensajes2 = Messageuser::find(4)->conversaciones()->get();
echo $mensajes;
echo $mensajes2;
消息模型
use Illuminate\Database\Eloquent\Model;
class MessageUser extends Model {
protected $table ="message_user";
public function conversaciones(){
return $this->hasMany('App\Message','id_message','id');
}
}
UPDATED2
当我尝试在视图中排序时出现Illegal offset type
<?php namespace App;
use Illuminate\Database\Eloquent\Model;
class Message extends Model {
protected $table="messages";
public function chat()
{
return $this->belongsTo('App\MessageUser','id');
}
}
答案 0 :(得分：2)
关系是hasMany，因此会返回一个收集集，而不是一个＆＃34; echoable＆＃34;事情：
$mensajes = Messageuser::find(1)->conversaciones()->get();
$mensajes2 = Messageuser::find(4)->conversaciones()->get();
\dd($mensajes, $mensajes2);
这将返回转储的两个Collection个对象。另请注意，您可以使用：
$mensajes = Messageuser::find(1)->conversaciones;
获得相同的回报。
现在您想加入结果，您可以使用merge类中Collection的内置方法：
$mensajes->merge($mensajes2);
基于created_at进行合并：
$mensajes = $mensajes->keyBy('created_at');
$mensajes->merge($mensajes2->keyBy('created_at'));
