how to retain drop-down menu selected state when the page reposts.

[louis_coetzee]

It's common courtesy to ensure that a form with validation problems reposts with the fields still filled in, so the user doesn't have to start over, by echoing the variables in the Value attribute of the text fields, but I also want to have a drop-down menu to be sticky and retain its selected state when the page reposts.

How are you creating your drop down box? Static or dynamic?

[louis_coetzee]

It's basically a static dropdown on a registration page, it then posts, validates, if errors are detected, i need the person to fix the problems, but the drop-down boxes lose their values. I need to retain this.

[waterssaz]

am i right in assuming the page posts back to self until no more errors exist?

$options = array ('One', 'Two', 'Three', 'Four');

echo "<select name=\"number\">\n";
foreach ($options as $optValue)
{
    $selected = ($optValue == $_POST['number']) ? ' selected="selected"' : '';
    echo "<option value=\"{$optValue}\"{$selected}>{$optValue}</option>\n";

}
echo "</select>\n";

 

EDIT: Corrected a couple errors

<form name="form"  method='post' action="">
