GET method returns 500 Internal server error

I'm new here so I have some question. I'm developing a web site, but there is some problem. I have map with tags, that onclick invokes a function "getObject(this.alt)".

function getObjects(object){
$.get("/sites/map/objects.php?t="+object, function(data) {

It executes script object.php were t= area tags alt attribute, the objects.php connects to MySql and returns objects row, but I get this kind of error:

GET 500 (Internal Server Error) jquery-latest.js:8706

Can you please help me? :)

This is the PHP code. Object is alt atribute from area tag in HTML file. It gets this alt and from that returns DB row with this alt name.

$object = $_GET['t'];
echo $object;
// Check connection
if (mysqli_connect_errno())
    echo "Failed to connect to MySQL: " . mysqli_connect_error();
$result = mysqli_query($con,"SELECT * FROM map WHERE `city`='$object' ORDER BY tips");
$result = mysqli_query($con,"SELECT * FROM map ORDER BY tips"); 
$old_tips = '';
$old_city = ''; 
while($row = mysqli_fetch_array($result))
  $tips = $row['tips'];
  $city = $row['city'];
      echo '<strong>'.$tips.'</strong><br>';
      echo $row['city'] . '<br>';
  echo $row['title'] . ' - <a href="'.$row['web'].'">' . $row['web']. '</a>';
  echo "<br>";
  $old_tips = $row['tips'];
  $old_city = $row['city'];

And the WEB server info:

  • Apache/2.2.21 (FreeBSD) mod_ssl/2.2.21 OpenSSL/0.9.8q DAV/2 PHP/5.3.8 with Suhosin-Patch SVN/1.7.1
  • MySQL client version: 5.1.59
  • PHP extension: mysql


mysqli_connect throws exception if mysqli module not installed or enabled. You'd activate this module in the php extions file

OR if your database is a mysql database and not mysqli, try to change from mysqli to mysql in your php code file

Your error is on the php.

Add this to the top of your php script:

ini_set("log_errors", 1);
ini_set("error_log", "/tmp/php-error.log");

Then check the log:

tail -f /tmp/php-error.log

So I solved problem like this. Cheked the PHP extension, changed mysqli_... to mysql_... Cheked the SQL user privilegies and changed them to be suitable to my problem. And I had database address written "localhost" because it runs on other server, not mine but when given to mysql_connect() the address like in IP, then the connection established right. And whola it worked, thanks everybody for help. :)

Now it looks something like this:

$connection = mysql_connect("db_addr","sql_user","password");
// Check connection
if (!$con)
    die ("Could not connect: " . mysql_error());
echo "Connection successfully <br>";

mysql_set_charset('utf8' , $connection);
