How Can I Dynamically Populate Dropdowns with Enum Values from a MySQL Database?

Retrieving Enum Values from a MySQL Database

Question:
Can I dynamically populate dropdowns with enum values from a MySQL database?

Answer:
Yes, it is possible to retrieve enum values from a MySQL database. Here's a PHP function that can extract them:

<code class="php">function get_enum_values($table, $field)
{
    // Fetch the data type of the specified field
    $type = fetchRowFromDB("SHOW COLUMNS FROM {$table} WHERE Field = '{$field}'")->Type;
    
    // Extract the enum values from the data type
    preg_match("/^enum\(\'(.*)\'\)$/", $type, $matches);
    
    // Convert the matched string into an array of values
    $enum = explode("','", $matches[1]);
    
    // Strip the quotes from the values
    $enum = array_map('stripslashes', $enum);
    
    return $enum;
}</code>

Usage:

To use this function, you can pass the table name and field name as arguments:

<code class="php">$enumValues = get_enum_values('my_table', 'my_field');</code>

The $enumValues variable will then contain an array of valid enum values for the specified field.
