Hi,

I am new to PHP and tried the following which did not work.
Can you explain why ?

function generateSelect($name = '', $options = array())
{
$html = '’;
foreach ($options as $option => $value)

{$html .= ”.$option.”;}

$html .= ”;
return $html;
}

$companies = array(
‘Microsoft’ => 1,
‘Google’ => 2,
‘Apple’ => 3);

$html = generateSelect(‘company’, $companies);

Essentially you would use php to query the data base.
Example of Connection:
// create connection
$MySQLserver = “localhost”;//the server of the MySQL (ie, localhost)
$username = $_POST['username']; //the username for the DB (ie, root, web, whatever)
$password = htmlspecialchars($_POST['password']); //the password for that username
$DBname = $_POST['DBname'];
$connection = mysql_connect(“$MySQLserver”,”$username”,”$password”);
// select database
// change DBname to the DB that you are using
$db = mysql_select_db(“$DBname”, $connection);
// create SQL statement
// you will need to create the select statement
$sql = “select …….”
// submit the select statement
$sql_result = mysql_query($sql,$connection);

//get results you want to add to the select array
//there are lots of ways to do this but this is just one way
foreach($sql_result as $keynumber => $keyvalue)
{
// we are going to store the data in a string and then convert to array
$mydata .= $mydata + $keyvalue['column name']+’#';
}
$companies = preg_split(‘#’,$mydata);
And then you would just pass $companies as in the posted example.

I tried to modify your function to minimize user interaction and select the appropriate department (based on referrer) from the list. When doing so, it selects the appropriate option, then each option thereafter… Any thoughts?

function generateSelect($name = ”, $options = array(), $selected) {
$html = ”.”\n”;
foreach ($options as $option => $value) {
if($selected==$value){$select=’selected=”selected”‘;}
$html .= ”.$option.”.”\n”;
}

$html .= ”.”\n”;
return $html;
}

Useless tutorial for beginners when you don’t bother to show a “complete” preview on how it should be done.

Beginners has no way to understand what you mean by
“$html = generateSelect(‘company’, $companies);”

$companies = array(
‘Microsoft’ => 1,
‘Google’ => 2,
‘Apple’ => 3
);

Using your example, is it possible to have this drop down list, for example, load up with ‘Apple’ (option #3) being PRE-selected?
