title: Passing jQuery variable to PHP - 500 Internal Server Error
body: <p>I am trying to pass a jQuery value to PHP as follows:</p>
  
  <pre><code>var your_var_value=1200;
  
  $.ajax({
      type: "POST",
      url: "scripts/php/controllers/tariff.fare.controller.php",
      data: { var_value: your_var_value},
      error:function(request){alert(request.statusText)},
      success:function(result){
          alert(your_var_value);
      }
  });
  </code></pre>
  
  <p>To the following:</p>
  
  <pre><code>&lt;?php
  
  require_once('models/sql.php');
  require_once('models/server.php');
  require_once('models/journey.php');
  
  class TariffFareController {
  
      // If there is no fixed fare, use route calc
      if ($fixed_fare_result == null) {
  
          $distance=$_POST['var_value'];
  
          if ($distance &gt; 1100) {
              $fare = 222.00;
          }
          else {
              $fare = 111.00;
          }
  
          //MORE CODE
  
  }
  </code></pre>
  
  <p>But when I do this I get a <code>500 Internal Server Error</code></p>
  
  <p>I know the URL I am passing this to is correct, any ideas ?</p>
