Show a user's country flag in their profile and comment

Sounds like something you'd have to program yourself... which would take working knowledge of PHP, MySQL, CSS and Drupal's internal workings. It sounds really easy to do (that's the advantage of working with something as flexible as Drupal), but... if you're a beginner at all these things, like me, it will take you plenty of work and study and trial and error.

Yep, definitely sounds like you need to customize the theme in the profile and comment template files. If the values in the field line up nicely with the names of the graphic files (ie "USA" = "usa.png"), it should be fairly simple. Check out Customising the user profile layout to get you started. Once you grasp that, theming comments will follow a similar approach.

I know this is an old topic, but I thought i would share one easy solution for those who wish to do this.

You will need to add a new user profile field, visit:
www.yourwebsite.com/admin/user/profile

I put mine in a category called "Personal Information"

Create a new "list selection" field

Add the following:

Title: Country
Form name: profile_country
Exlplaination: Which country do you live in?

Selection options:

Abkhazia
Afghanistan
Akrotiri
Aland
Albania
Algeria
American Samoa
Andorra
Angola
Anguilla

Make sure this is Public field, content shown on profile page and on member list pages.
Make sure the User Must enter a value
Make sure it is visible in registration field

Now, you'll need to insert the following where you want it in your custom user pages template:

<div class="fields">Country: <?php
//check if image exists
$Flagname = "http://www.yourwebsite.com/files/image/country_flags/". check_plain($user->profile_country).".gif";
if($img = @GetimageSize($Flagname))
{
echo '<img src="'.$Flagname.'" alt="Icon represents '.check_plain($user->profile_country).'" width="16" height="11" />';
}
else
{
echo "";
}
?> <?php print check_plain($user->profile_country) ;?></div>

Note: Now, this is not awesome, and you will have to change the Famfam fam names from their ISO names, to the ones in the list above, there is a better way (which would be to use php to convert from a DB table), i just haven't done it... All it needs is a very simple bit of php. I'll try, but would prefer a pro to do it.

Note: where we store the images: http://www.yourwebsite.com/files/image/country_flags/
Change accordingly.

Now, get some lovely icons, i recommend FamFamFam, cos he is a legend, and his icons are great:
http://www.famfamfam.com/lab/icons/flags/

This works for me, hopefully for you too.

Taking it to the next level:

List of names and ISO's

The following website has some great code which could be the basis of this mod. I honestly reckon this should be rolled into the core of Drupal, considering it is so useful, and Drupal is global. if there are issues with Copyrights for images, I am sure there is a set available with no restrictions.

All is needed is to convert some php to read the row where we stored the table name above. The example below is taken from:
http://27.org/isocountrylist/

@ $db = mysql_pconnect($hostname, $dbusername, $dbpasswd);
if (!$db) {
    print "Failed to connect to the database.  Please try again later.\n";
    exit;
}
mysql_select_db($dbname);
$sql = "select id,name from country order by iso";
if (!(@ $result = mysql_query($sql))) {
    print "There was an error running your query:<p>\n". $sql . "<p>\n";
}
print '<select name="country"><br>\n';
print '<option value="">  Choose One   ';
while ($row = mysql_fetch_row($result)) {
    $country_iso   = $row[0];
    $country_name  = $row[1];

    print "<option value=\"$country_iso\"";
    if ($_REQUEST["country"] == $country_iso) { print " selected"; }
    print "> $country_name <br>\n";
}
print '</select>\n';

I'll leave that for a php guru, anhow, i reckon this is way better than using a massive ip to flag, is quicker, and is foolproof.

Any php legends who are up for it, please go for it and post back.
Cheers...
