PHP Tutorial: Put MySQL ENUM values into drop down select box

If you have an ENUM field in your table schema then you don’t want to go through the hassle of re-writing out all of the different ENUM values when you do an online form or CMS update system. This piece of code will take all of your ENUM values and put them into a select box so the choices displayed in the drop down are always up to date.

$table_name = "your_table_name"
$column_name = "field_with_enum_options";

echo "<select name=\"$column_name\">";
$result = mysql_query("SELECT COLUMN_TYPE FROM INFORMATION_SCHEMA.COLUMNS
    WHERE TABLE_NAME = '$table_name' AND COLUMN_NAME = '$column_name'")
or die (mysql_error());

$row = mysql_fetch_array($result);
$enumList = explode(",", str_replace("'", "", substr($row['COLUMN_TYPE'], 5, (strlen($row['COLUMN_TYPE'])-6))));

foreach($enumList as $value)
    echo "<option value=\"$value\">$value</option>";

echo "</select>";
