inserting values into multiple tables PHP

Question

I am stuck at writing this kind of service where information is being added into multiple tables. my connection is established column names are perfect but don't know why my first insert query doesn't work. FYI i am testing this service by REST api Client. Please help me out..

<?php
include_once 'connection.php';
$json = "";
$userId;
$shareId;
if ($_SERVER ['REQUEST_METHOD'] == "POST") {

    if (isset ( $_POST ["alarmId"] ) && isset ( $_POST ["phone"] ) && isset ( $_POST ["title"] ) && isset ( $_POST ["time"] ) && isset ( $_POST ["ringtone"] ) && isset ( $_POST ["snoozeDuration"] ) && isset ( $_POST ["gentleWakeup"] ) && isset ( $_POST ["mon"] ) && isset ( $_POST ["tues"] ) && isset ( $_POST ["wed"] ) && isset ( $_POST ["thu"] ) && isset ( $_POST ["fri"] ) && isset ( $_POST ["sat"] ) && isset ( $_POST ["sun"] ) && isset ( $_POST ["isOn"] ) && isset ( $_POST ["isShared"] ) && isset ( $_POST ["isRepeating"] ) && 
     //share content
    isset ( $_POST ["shallInform"] ) && isset ( $_POST ["textMsg"] ) && isset ( $_POST ["contacts"] )) {

        // alarm content..
        $alarmId = $_POST ["alarmId"];
        $phone = $_POST ["phone"];
        $title = $_POST ["title"];
        $time = $_POST ["time"];
        $date = $_POST ["date"];
        $ringtone = $_POST ["ringtone"];
        $snoozeDur = $_POST ["snoozeDuration"];
        $gentleWake = $_POST ["gentleWakeup"];
        $mon = $_POST ["mon"];

        $thu = $_POST ["thu"];
        $fri = $_POST ["fri"];
        $sat = $_POST ["sat"];
        $sun = $_POST ["sun"];
        $isOn = $_POST ["isOn"];

            }


            //inserting into share table..

            $insShare = "INSERT INTO share (alarmId,userId,shallInform,textMsg) VALUES ('$alarmId','$userId','$shallInform','$textMsg')";

                $shareResult = mysqli_query($shareAlarm);

                if($shareResult){

                else{

        } else {

    enter code here

mysqli_close ( $con );

if ($json != "") {

    echo json_encode ( $json );

            "message" => "please set all required values before transmitting to server" 
    );
    echo json_encode ( $json );
}
?>

My connection.php file is

<?php

            define("SERVER", '127.0.0.1');
            define("USER", 'root');
            define("PASSWORD", "");
            define("DB", 'alarm_clock');


            $con = new mysqli(SERVER,USER,PASSWORD,DB);

            if ($con->connect_errno){
                die("Database Connection Failed");
                exit();

            }

Answer 1

It should work

$s1 = "INSERT INTO alarm (`alarmId`,`phone`,`title`,`time`,`date`,`ringtone`,`snoozeDuration`,`gentleWakeup`,`isMon`,`isTues`,`isWed`,`isThu`,`isFri`,`isSat`,`isSun`,`isOn`,`isShared`,`isRepeating`) VALUES ('$alarmId','$phone','$title','$time', '$date' ,'$ringtone','$snoozeDur','$gentleWake','$mon','$tues','$wed','$thu','$fri','$sat','$sun','$isOn','$isShared','$isRepeating')";

Please noted that time, date etc are mysql reserved keywords, you should use `time` instead of time and so on
