Question

I installed MAMP on my mac to run sql and apache server on my local machine to host a website i am working on. Now i am using phpmyadmin to control and create my database tables. I am running into a couple of issues with inserting values into the tables. I have two pages namely, test.html and test.php. test.html has a form with username and password and it calls a javascript to post the values to test.php.Following is code snippet of how i am posting the value on test.html.

$.post("test1.php",
 {
 username: username,
     password: password

  },
 function( dataFromServer ){
     alert(dataFromServer);     
 }
);

I am unable to insert the two values in the table. When i click submit, i receive the following error in firefox:

POST http://localhost:8888//test1.php
500 Internal Server Error

Following is code snippet of how i insert values on test.php:

include('config.php');
$tbl_name="table1";
$username=$_POST['username'];
$password=$_POST['password'];

$sql="INSERT INTO $tbl_name(col1,col2)VALUES('$username','$password')";
$result=mysql_query($sql);

Can anybody point the mistake here. I am new to web coding so this might be really trivial.

Thanks,

Answer 1

500 internal error means there is something wrong in your php file.
Check the following things

1.Is there any syntax error in your php file.

2.

$sql="INSERT INTO $tbl_name(col1,col2)VALUES('$username','$password')"; 

should be written as

$sql ="INSERT INTO $tbl_name(col1,col2)VALUES('".$username."','".$password."')";

Also,always sanitize data before you use it.
