variable not passing to next page

[dolcezza]

I have a dropdown populated by a database.

When I try to insert the selection into another table, it isn't working.

The form is getting the venueid column, I tested that by making it visible.

 

If I echo $venueid in the next page, I get nothing.

Any help for a newbie is appreciated. I only posted relevant parts of code.

Form:

 Venue: <select name="venueid" id="venueid">"
    <?
$query = "SELECT * FROM venues ORDER BY venue ASC";
$result = mysql_query($query) or die("there was an error:".mysql_error());
     if(mysql_num_rows($result)) {
       // we have at least one user, so show all users as options in select form
       while($row = mysql_fetch_row($result))
       {
          echo "<option value=\"$row[0]\">$row[1]</option>";
       }
     } else {

       echo "<option value=\"\">No venues created yet</option>";
     }
    echo '</select>';
?>

insert page:

$venueid=$_POST['venueid'];
$eventcode = md5(uniqid(rand()));
$query = "INSERT INTO events (date,venueid,authorid,eventcode) VALUES ('$date_for_mysql','$venueid','$authorids','$eventcode')";

here is the whole insert page:

I am posting this too because it is getting the venueemail, and sending the email. I thought it may help.

Thanks.

$authorlast=$_POST['authorlast'];
$venueid=$_POST['venueid'];
$eventcode = md5(uniqid(rand()));

$venuequery = ("SELECT * FROM `venues` WHERE `venueid`='{$_POST['venueid']}'");
$venueresult=mysql_query($venuequery);
$venueinfo = mysql_fetch_array($venueresult);
//$venueid = $venueinfo['venueid'];
$venueemail=$venueinfo['email'];


$date_array=explode("/",$_POST["date"]);
$date_for_mysql=$date_array[2]."-".$date_array[0]."-".$date_array[1];

$authorids = implode($_POST['authorid'],",");

$query = "INSERT INTO events (date,venueid,authorid,eventcode) VALUES ('$date_for_mysql','$venueid','$authorids','$eventcode')";

$my_result=mysql_query($query);
if(!$my_result){echo mysql_error();}
else {
        
include('events.php');
        // get code from database
        // mail code to venue
        $send = mail($venueemail , "Connecting Authors Event Form" , "Thank you for booking your event with Connecting Authors (formerly KatzConnects)..\n\nPlease fill out our form by clicking the link below:\nhttp://www.connectingauthors.com/admin/eventform.php?id=".$eventcode."\n\nPlease do not reply, this is an automated mailer.\n\nThanks", "FROM: [email protected]");
}

In the code below, what's $row[0] and $row[1] referring to?

Venue: <select name="venueid" id="venueid">"
    <?
$query = "SELECT * FROM venues ORDER BY venue ASC";
$result = mysql_query($query) or die("there was an error:".mysql_error());
     if(mysql_num_rows($result)) {
       // we have at least one user, so show all users as options in select form
       while($row = mysql_fetch_row($result))
       {
          echo "<option value=\"{$row[0]}\">{$row[1]}</option>";
       }
     } else {

       echo "<option value=\"\">No venues created yet</option>";
     }
    echo '</select>';
?>

in the database, row 0 is venueid and row 1 is the venue name.

The venueid is unique, the name is what I want people to see obviously, but I use it's unique id

[Ken2k7]

Try:

Venue: <select name="venueid" id="venueid">"
    <?php
$query = "SELECT * FROM venues ORDER BY venue ASC";
$result = mysql_query($query) or die("there was an error:".mysql_error());
     if(mysql_num_rows($result)) {
       // we have at least one user, so show all users as options in select form
       while($row = mysql_fetch_array($result))
       {
          echo "<option value=\"{$row[0]}\">{$row[1]}</option>";
       }
     } else {

       echo "<option value=\"\">No venues created yet</option>";
     }
    echo '</select>';
?>

It worked, thank you...

I see you changed  while($row = mysql_fetch_row($result))

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

 

do you mind explaining why one works and the other doesn't? I appreciate it if you are willing, I'm trying to get a better understanding.

Thanks again.

actually... I spoke too soon... it is writing the word "array" to the database instead of the id#.
