I have a problem with my code somewhere, when the user selects the event

  • 0

I have a problem with my code somewhere, when the user selects the “event” in the first select menu, it updates the 2nd menu with options from the database. This second menu is not updating in some browsers such as IE and Chrome, however works fine in others like firefox.

I’m not quite sure what is the problem, any help would be appreciated.
Thanks!

The code I currently have is below-

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script type="text/javascript">
function events()
{
   document.eventform.submit();
}
</script>

<?
require_once('dbconnect.php');

$sql="SELECT id, event FROM events ORDER BY id DESC";
$result=mysql_query($sql);

$options1="";

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

$id=$row["id"];
$event=$row["event"];
$options1.="<OPTION VALUE=\"$event\">".$event;'</OPTION>';

}
$eventis = $_GET['event'];
$sql = "SELECT * FROM events WHERE event='$_GET[event]' ORDER BY id DESC";  
$result=mysql_query($sql);

$options2="";

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

$id=$row["id"];
$location1=$row["location1"];
$location2=$row["location2"];
$location3=$row["location3"];
$location4=$row["location4"];
  $options2.="<OPTION VALUE=\"$location1\">".$location1;'</OPTION>';
$options2.="<OPTION VALUE=\"$location2\">".$location2;'</OPTION>';
$options2.="<OPTION VALUE=\"$location3\">".$location3;'</OPTION>';
$options2.="<OPTION VALUE=\"$location4\">".$location4;'</OPTION>';

}
?>
</head>
<body>


<form action=""  name="eventform" class="style1" id="eventform" onchange="events()">
  <p align="center">


Step 1: 
  <select name="event" id="event">
  <OPTION VALUE=0>Select Event:
  <?=$options1?>
  </select> 
  &nbsp;</label>
  <?php echo $eventis ?></p>
  <div align="center"></div>
  <div align="center"></div>
 </form>

 <form action='sale.php' name= 'locationform' method='get'>

<div id="eventname"></div>
<p align="center">Step 2: Select the location:
  <select name="location"  id="location">
 <OPTION VALUE=0>Select Location:
  <?=$options2?>
 </select>
</p>
<p align="center">
<input name="event" type="hidden" id="event" value="<?php echo $eventis ?>">
<input name="operator" type="hidden" id="operator" value="<?php echo $operator ?>">
<input type="submit" value="Submit" />
</form>
</p>

    Well for starters your not selecting your form

    document.eventform.submit();

    Does not select your form, you will need to use

    document.forms["eventform"].submit()

    or select the form using getElementById.

    Second your html is a bit of a disaster 🙂 but I don’t think that’s the issue. Just thought I would let you know.
