Automatically populate Country field when adding ads

There is one thing I’m missing on basic Classipress installation and that is automatic population of Country field when adding an ad. You could buy a plugin called Advanced Custom Fields for ClassiPress but this plugin offers much more than we need here.

This mod will automatically populate Country field with the country you are surfing from, with the help of GeoLite data created by MaxMind, available from http://www.maxmind.com.

This modification was tested on Classipress 3.3.X, 3.4.x and 3.5.x

This tutorial requires you to change this file (version prior to 3.4):
wp-content/themes/classipress/includes/forms/step-functions.php

And this file is you are using version 3.4 or newer:
wp-content/themes/classipress/includes/custom-forms.php

and add these two files into the same folder:

geoip.inc
GeoIP.dat

You can obtain these two files here:
GeoIP.zip

These two files were downloaded from MaxMind’s web page.

It is recommended to make backup of files before making any changes.

Step 1

Now open file step-functions.php (custom-forms.php for CP v3.4) and do this changes:

Find this code (it’s around line 19):

if ( !function_exists('cp_formbuilder') ) {
function cp_formbuilder($results, $post = false) {
global $wpdb, $cp_options;

and add this code after it:

// Start of geoip code
require_once( get_template_directory() . '/includes/forms/geoip.inc' );
$gi = geoip_open(get_template_directory() . '/includes/forms/GeoIP.dat', GEOIP_MEMORY_CACHE);
$country = geoip_country_name_by_addr($gi, $_SERVER['REMOTE_ADDR']);
geoip_close($gi);
// End of geoip code

Then around line 86 (case ‘drop-down’:) find this code:

if ( $option == $post_meta_val )

and change it to:

if ( $option == $post_meta_val || ($args['value'] == $country && !$post_meta_val) )

Don’t forget to copy two files I mentioned before to the same folder this file is in. You can move them to a different location, but make sure to change the code accordingly.

Step 2

Step 2 is optional and is meant for those who have changed the names of Countries in Classipress custom field Country – cp_country.

If you haven’t touched names of the countries in that list, then you should skip this step.

You have to open file geoip.inc and change array GEOIP_COUNTRY_NAMES according to the values in cp_country.
