How to Retrieve Enum Values from a MySQL Database for Dynamic Dropdown Population?

Retrieving Enum Possible Values from MySQL Database

To dynamically populate dropdowns with enum possible values stored in a MySQL database, the database schema must be queried to extract the respective enum types. In MySQL, the SHOW COLUMNS FROM [table_name] statement can be utilized to retrieve column-related information, including enum types.

Here is a PHP function that implements this approach:

function get_enum_values($table, $field)
{
    $type = fetchRowFromDB("SHOW COLUMNS FROM {$table} WHERE Field = '{$field}'")->Type;
    preg_match("/^enum\(\'(.*)\'\)$/", $type, $matches);
    $enum = explode("','", $matches[1]);
    return $enum;
}

By invoking this function with the appropriate table and field names, the possible values for the specified enum field can be obtained. This allows for easy and automated population of dropdowns with the desired values. It's important to note that this function strips the quotes from the enum values to provide them in a more usable format.
