PHP Question

Making Ideone API work on Codeigniter (ajax, javascript,soapclient)

This is my first time to use Codeigniter. So sorry if my question is noob.
I got codes from this site: Working with IDE One API (Full project code is here) and now, I am trying to use it in codeigniter.

I was able to make it work up to the javascript part below (since it was able to check if 'source' has value).


$(document).ready(function() {
$('#myform').submit( function(){
var data = $(this).serialize();
var source = $('textarea#source').val();

if( source == '' ) {
alert( 'No source code provided');
return false;

$(this).append('<div class="loading">Processing...</div>');

type: "POST",
url: "<?php echo base_url();?>student/submit",
dataType: 'json',
data: data + '&process=1',
cache: false,
success: function(response){
if( response.status == 'success' ) {
$('.meta').text( response.meta );
$('.output').html('<strong>Output</strong>: <br><br><pre>' + response.output + '</pre>');

if( response.cmpinfo ) {
$('.meta').after('<div class="cmpinfo"></div>');
$('.cmpinfo').html('<strong>Compiler Info: </strong> <br><br>' + response.cmpinfo );

} else {
//$('.output').html('<pre>' + response + '</pre>');
alert( response.output );
//alert( response.msg );

return false;

My problem is I'm not sure whether it is able to reach the function "submit" in my student

controller or the problem lies in the function itself.


public function submit(){
$user = 'myuser';
$pass = 'mypassword';
$code = '';
$input = '';
$run = true;
$private = false;

$subStatus = array(
0 => 'Success',
1 => 'Compiled',
3 => 'Running',
11 => 'Compilation Error',
12 => 'Runtime Error',
13 => 'Timelimit exceeded',
15 => 'Success',
17 => 'memory limit exceeded',
19 => 'illegal system call',
20 => 'internal error'

$error = array(
'status' => 'error',
'output' => 'Something went wrong :('

//echo json_encode( array( 'hi', 1 ) ); exit;
//print_r( $_POST ); exit;

if ( isset( $_POST['process'] ) && $_POST['process'] == 1 ) {
$lang = isset( $_POST['lang'] ) ? intval( $_POST['lang'] ) : 1;
$input = trim( $_POST['input'] );
$code = trim( $_POST['source'] );

$client = new SoapClient( "" );

//create new submission
$result = $client->createSubmission( $user, $pass, $code, $lang, $input, $run, $private );

//if submission is OK, get the status
if ( $result['error'] == 'OK' ) {
$status = $client->getSubmissionStatus( $user, $pass, $result['link'] );
if ( $status['error'] == 'OK' ) {

//check if the status is 0, otherwise getSubmissionStatus again
while ( $status['status'] != 0 ) {
sleep( 3 ); //sleep 3 seconds
$status = $client->getSubmissionStatus( $user, $pass, $result['link'] );

//finally get the submission results
$details = $client->getSubmissionDetails( $user, $pass, $result['link'], true, true, true, true, true );
if ( $details['error'] == 'OK' ) {
//print_r( $details );
if ( $details['status'] < 0 ) {
$status = 'waiting for compilation';
} else {
$status = $subStatus[$details['status']];

$data = array(
'status' => 'success',
'meta' => "Status: $status | Memory: {$details['memory']} | Returned value: {$details['status']} | Time: {$details['time']}s",
'output' => htmlspecialchars( $details['output'] ),
'raw' => $details

if( $details['cmpinfo'] ) {
$data['cmpinfo'] = $details['cmpinfo'];

echo json_encode( $data );
} else {
//we got some error :(
//print_r( $details );
echo json_encode( $error );
} else {
//we got some error :(
//print_r( $status );
echo json_encode( $error );
} else {
//we got some error :(
//print_r( $result );
echo json_encode( $error );

It just stays on the part where the "Processing" shows and nothing happens after that. Please help me. Thank you so much :(

I'm not sure if this would help solve the problem. But when I traced the Network Requests, I am getting "Disallowed Key Characters" as a "Response". I assume this is because of the Request URL:


Am I getting anywhere? Pls help


I got it! Thanks to a friend who taught me about that "CTR+SHIFT+I" of Chrome. The Request URL really is the error.

I just changed this part in the script's AJAX post request:

 url: "<?php echo base_url();?>student/submit",


    url: "submit",

The response/error sent by CI which is "Disallowed Key Characters" was because of the excess php codes getting mixed up with the Request URL ( the one with base_url() ).

Thanks to this problem(no matter how simple this is), I was able to have a very nice introduction on codeigniter workarounds.
