php - How to insert data from a json-object to a database -


i'm pretty new json, i'm trying insert data json database table. keep getting errors: notice: undefined index: subject notice: undefined index: message

<?php $jsondata = '{   "p1" : [ { "subject": "something", "message": "something" }, { "subject": "something111", "message": "something11" } ] }';  $data = json_decode($jsondata, true); $p1 = $data['p1'];  $sql = "insert          table(subject,         message)         values('".$p1['subject]."', '".$p1['message]."'"); $result = $mysqli->query($sql);  ?>

there many mistakes in code.

1.$p1 multidimensional array treating array

2.you have forget comma(') before ] in query

3.you have close " @ wrong place in query should @ last after values bracket.

use code

$jsondata = '{   "p1" : [ { "subject": "something", "message": "something" }, { "subject": "something111", "message": "something11" } ] }';  $data = json_decode($jsondata, true); $p1 = $data['p1']; foreach($p1 $val) {     $sql = "insert table(subject,message) values('".$val['subject']."', '".$val['message']."')";     $result = $mysqli->query($sql); }
