not detecting true variable

ok i have this variable set to true and i do not understand why it is not working:(

PHP Code:


		
			
    $grabfields= $DB_site->query("SHOW FIELDS FROM " . TABLE_PREFIX . "journal_settings");

    while($field= $DB_site->fetch_array($grabfields))

    {

        if($field['Field'] == "version")

        {

            $versionexists= true;

        }

        else

        {

            $versionexists= false;

        }

    }

    $DB_site->free_result($field);

    

    if($versionexists)

    {

        echo "VERSION EXISTS!";

        $checkversion= $DB_site->query_first("SELECT version FROM " . TABLE_PREFIX . "journal_settings LIMIT 1");

        $prevversion= $checkversion['version'];

        echo $prevversion;

    }

    else

    {

        echo "NO VERSION DETECTED!";

        $upgrade= true;

        $prevversion= "1.0.1";

    }

it seems to keep thinking $versionexists is false even though it is true. also the field "version" does exist in the table.

A few things:
- If the table contain more columns (i.e. A, version, C), the loop will be executed 3 times. $versionexist will be true after 'version' is read, and will be set to false again when C is read. Set $versionexist to false before entering the while, add a break after $versionexists = true, and remove the else part.

- Is 'Field' with an initial capital?
