Ben MySQL saklanan parametars ile bir javascript işlevi çağırmak istiyorum. Tüm bunlar bir onClick olay oluyor.

İşte javascript kodu:

    function getFile() {
  if (window.XMLHttpRequest) {              
    AJAX=new XMLHttpRequest();              
  } else {                                  
    AJAX=new ActiveXObject("Microsoft.XMLHTTP");
  }
  if (AJAX) {
     AJAX.open("POST", "gmap.php", false);                             
     AJAX.send("searchField=" + searchField.value);
     return load(AJAX.responseText);   

  } else {
     return false;
  }                                             
}

So, the gmap.php is echoing the parameters for the javascript load function. But it doesn't load the parameter because the function is called before the MySQL query in gmap.php is executed. I've tried sync and async AJAX. If I try to call the javascript function from PHP, it doesn't get executed, because it is called on a onClick event, and this is inside a div. Please help me, I'm doing this over a week now. I've tried everything.

Burada MySQL sorgu ile php kodu:

<?php
header( 'Content-Type: text/html; charset=UTF-8' );
mb_internal_encoding( 'UTF-8' );
$a = $_POST['searchField'];
$dbhost = "localhost";
$dbuser = "*******";
$dbpass = "*******";
$dbname = "citydb";



    //connect sql
mysql_connect($dbhost, $dbuser, $dbpass);

    //select db
mysql_select_db($dbname) or die(mysql_error());
    //retrieve data
//$city=$_GET['city'];
    //escape user input to help prevent SQL injection
//$city=mysql_real_escape_string($city);
    //query
mysql_query('SET CHARACTER SET utf8');
$result=mysql_query("SELECT citystart, cityend FROM cityids WHERE city='$a' ");
if(!result) {

    die("Database query failed: " . myql_error());
    }

while($row=mysql_fetch_array($result)) {


    $lat=$row['citystart'];
    $lng=$row['cityend'];


}


    echo $lat;
    echo ", ";
    echo $lng;



?>
