Hey there
I am using phpMyAdmin and MySQL to develop a dbase application.
I have a dropdown menu on one of the pages which gets populated automatically with data from a table in the database. The code for this is as follows: - $sql3="SELECT ID, UploadDate FROM Telkom";
-
$result2=mysql_query($sql3);
-
$options="";
-
-
while ($row=mysql_fetch_array($result2)) {
-
-
$id=$row["ID"];
-
$date=$row["UploadDate"];
-
$options.="<OPTION VALUE=\"$id\">".$date;
-
-
The code for the actual dropdown menu is as follows:
-
-
<form name="selectdata" action="select_telkom_data.php" method="post">
-
<SELECT NAME="thedate">
-
<OPTION>Choose
-
<?=$options?>
-
</SELECT>
-
<input type="submit" name="Submit" value="Go">
-
</form>
-
-
As you can see there is an additional php script (select_telkom_data.php). This script is supposed to check the $date variable against the UploadDate table and then return the correct record based on the date the user has selected in the dropdown menu.
-
-
The code for select_telkom_data.php looks like this:
-
-
<?php
-
-
include "admin/dataw.php";
-
include("global.inc.php");
-
$sysadminemail = "webmaster@dtmsi.org";
-
-
process_login();
-
die();
-
-
-
function process_login() {
-
global $dbhost;
-
global $dbuser;
-
global $dbpass;
-
global $db;
-
-
// define homepage and text variables
-
global $homepage;
-
global $homedir;
-
global $sysadminemail;
-
global $userstable;
-
-
-
$date=$_POST['thedate'];
-
$link = mysql_connect("$dbhost", "$dbuser", "$dbpass")
-
or die('Could not connect: ' . mysql_error());
-
echo 'Connected successfully';
-
mysql_select_db("$db") or die('Could not select database');
-
-
$query = "SELECT * FROM Telkom WHERE UploadDate='$date' ";
-
$result = mysql_query($query) or die('Query failed: ' . mysql_error());
-
-
-
$num_rows = mysql_num_rows($result);
-
$row = mysql_fetch_array($result);
-
-
-
// test -- does the date exist
-
if ($num_rows < 1) {
-
print "<HTML>";
-
print "<HEAD>";
-
print "<TITLE>";
-
print "Error";
-
print "</TITLE>";
-
print "<BODY>";
-
print "<CENTER>";
-
print "<B><CENTER>Sorry - no records exist. ";
-
-
-
}
-
else {
-
-
-
include("show_telkom_data.php");
-
-
mysql_close($link);
-
}
-
-
-
}
-
-
?>
[Please use CODE tags when posting source code. Thanks! --pbmods]
The script connects to the database, but it doesn't return any records from the Telkom table. In other words, all I get is the message 'Sorry - no records exist'.
What am I doing wrong?
Thanks guys!

The value that you are getting from your selection is not the UploadDate, it's the id. The UploadDate is just the label of the option, not the value of it.
if you print_r($_POST) , you'll see the values that are being passed from the form.

ok, thanks very much! Just one more question though: I'm not entirely sure what to change to make it work. I would REALLY appreciate if you could help me out one more time.
shot!

Think about it.
What condition are you using to get the data from your database?
What values are you provided to get that data?
Like I said, use print_r($_POST) and figure it out. ^_^
hey, thanks for all your help! I managed to figure it out up to a point where the correct records get selected and displayed.

My drop down list is populated from a static array in my codebehind (c#)
code.
I set the selected index based on some known values(from DB), when the
screen shows up, dropdown list shows that the the first items is selected and
not the one assigned.
Please note that if I hardcode the dropdown items inside the .aspx file,
everything works fine.
Please point me to examples(infopath examples somehow don't show up for me!).

Dear Group,
I have a heirarchical set of database tables, say - "order" and "order_type"
and want to display a series of orders in a grid control, and in place of
the order_type foreign key identifier, I would like a dropdown combo box
(lookup from the "order_type" table) to change the type of the order. I also
need an update command button, a delete row button and also an insert new
row button.
I'm sure this is a very common design...

Hi folks,
If I want to select the first item in a DropDownList, I need to first select
any item other than the first item and then next I select the first item
which will then fire an event saying that I clicked the first item.
Why can't I just select the first item to get an event to fire without
having to first select any other item.
Thanks for any tips.

I have a 2 drop down lists in C# populated with data from a SQL 2005 db.

I use databind() after the form has autoposted back after the insert but the 1st and 2nd drop down lists default back to the first item in the...
