Listbox is not displaying the correct information if at all

Jul 21st, 2007

Hello everyone I have some code listed below, well with this code I it does not display anything in the listbox. When I have it displaying the stuff in the listbox it does not display the correct stuff...like less than 10. I have put the line of code in bold. Can someone look at it and tell what I am missing. My goal is to have two list boxes, but they are not going to be dependent on each other.

>$sql = "SELECT `policy` AS 'policy' FROM `Premiums` where ID < 10";

This statement just doesn't make any sense in terms of SQL. And you got some strange (non standard ) apostrophe's there as well.

Iamthwee, what are you talking about ? the back ticks `` denote a field name or table name within mySQL proper syntax.

PHP fills these in for you if you don't use them.

Golffor1, without going into your code too much, ihave noticed your using row[0] and row[1].

However in your SQL query you're only selecting 1 field, therefore you will only have row[0]

Hi,

I am a newbie to PHP. what is the way to hold the selected value from the list. How does the return statement work in this context.

Brgds,

kNish

function enhanced_list_box_05($options){
$sql = "select " . $options['value_field'];
$sql .= " from " . $options['table'];
$result = mysql_query($sql)or die("error in SQL");
echo '<select name="', $options['value_field'],'" size="1">';
while ($row = mysql_fetch_array($result, MYSQL_NUM))
{
if($row[0] == $options['highlight_id']) {
echo '<option value="' . $row[0] . '"SELECTED>' . $row[0] . '</option>';
} else {
echo '<option value="' . $row[0] . '">' . $row[0] . '</option>';
echo $row[0];
}
}
echo '</select>';
return $row[0];
}
