Populating Drop Down List

gobbles

Hey All,

Im just trying to cut down on thousands of lines of code at the moment and hopefully someone could help me.

I have a drop down box and the "selected" value needs to be selected by a dynamic value that gets entered into the database, this is currently how im doing it:

              <?php
                if($modify_row[21] == "0") {
                  print "<option value=\" \"></option>\n";
                  print "<option value=\"1\">Active</option>\n";
                  print "<option value=\"0\" selected>In-Active</option>\n";
                } elseif ($modify_row[21] == "1") {
                  print "<option value=\" \"></option>\n";
                  print "<option value=\"1\" selected>Active</option>\n";
                  print "<option value=\"0\">In-Active</option>\n";
                }
?>

At the moment i have over 100 "options" and i think it would be a major waist of code doing it this way, can someone help me out please.

Its fairly straight forward, basically the option that is automatically selected needs to be the one coming from the database $modify_row[21].

Thanks All

So... you have over 100 different option values? Or, you have over 100 different SELECT fields with the two options you showed us?

I have over 100 option values ... the snippet of code there is only a brief show of my lame coding habits at the moment.

Imagine 98 more options

Wow... that's a lot of options. Are they hard-coded within the HTML, or are they derived from somewhere?

Only reason I ask, is because what came to my mind when I first read your post was a [man]for/man loop:

$options = array('In-Active', 'Active', 'Option #2', 'why 2?', 'because array indeces', 'start on', 'zero!');

for($i=0,$max=count($options); $i<max; $i++) {
    $selected = ($modify_row[21] == $i ? ' selected' : '');
    echo "<option value=\"$i\" $selected>" . $options[$i] . "</option>\n";
}

The options are hardcoded, as an example say i have 5 options as follows:

1
2
3
4
5

Using a form in another section, a user clicks on 4 and it gets stored in the database.

When they go to modify that form, i want the drop down to display 4 instead of the one thats at the top "1"

If that makes sense.

Right... that's what my code does. It re-creates the drop-down, but adds the "selected" tag to the option that matches the variable from your original post to make sure that their previous choice is the "selected" option by default.

HA, Ill be damned ... Thank you muchly for that
