android php mysql从app插入多行到数据库数据库

Question

My app holds a list of student id numbers, their names and grades, and I want to insert the entire list into a database. Each student should be in a row (id-name-grade, in one row).

I am using AsyncTask to send my info to the DB, and wanted to ask how can I send multiple rows (each one containing multiple variables)at once? If I need to send them all as one JSONObject how do I separate them back into the different students?

The tutorials I use to create my app: http://www.mybringback.com/android-sdk/13193/android-mysql-php-json-part-5-developing-the-android-application/ http://www.androidhive.info/2012/05/how-to-connect-android-with-php-mysql/

I have also found previous answers that deal with the php side of things but as I am new to php I didn't really get it inserting multiple mysql rows php Android

Answer 1

On your server side, send the data as an array of JSON objects, then insert objects in a foreach loop, try something like this (this untested, but should get you started):

<?php
//your sample input may look something like this:
//$json_input_string = '{0:["id":123,"name":"Jon Doe","grade":"A"],1:[...]}';
$input_data = json_decode($json_input_string);
foreach($input_data->data as $item)
{
     //$item->id, $item->name, $item->grade all accessible here
     //insert each record here in loop
}

?>

Make sure you are using using prepared statements
