I want to know Visitor country using PHP and display it in to a WordPress Page.But when I add PHP code in WordPress page or Post it give me error.
How can we add PHP code in WordPress Page and Post.
<?PHP
try{
function visitor_country()
{
$client = @$_SERVER['HTTP_CLIENT_IP'];
$forward = @$_SERVER['HTTP_X_FORWARDED_FOR'];
$remote = $_SERVER['REMOTE_ADDR'];
$result = "Unknown";
if(filter_var($client, FILTER_VALIDATE_IP))
{
$ip = $client;
}
elseif(filter_var($forward, FILTER_VALIDATE_IP))
{
$ip = $forward;
}
else
{
$ip = $remote;
}
$ip_data = @json_decode(file_get_contents("http://www.geoplugin.net/json.gp?ip=".$ip));
if($ip_data && $ip_data->geoplugin_countryName != null)
{
$result = array('ip'=>$ip,
'continentCode'=>$ip_data->geoplugin_continentCode,
'countryCode'=>$ip_data->geoplugin_countryCode,
'countryName'=>$ip_data->geoplugin_countryName,
);
}
return $result;
}
$visitor_details= visitor_country(); // Output Country name [Ex: United States]
$country=$visitor_details['countryName'];
WordPress does not execute PHP in post/page content by default unless it has a shortcode.
The quickest and easiest way to do this is to use a plugin that allows you to run PHP embedded in post content.
There are two other “quick and easy” ways to accomplish it without a plugin:
-
Make it a shortcode (put it in
functions.phpand have it echo the country name) which is very easy – see here: Shortcode API at WP Codex -
Put it in a template file – make a custom template for that page based on your default page template and add the PHP into the template file rather than the post content: Custom Page Templates
Answer：
You can’t use PHP in the WordPress back-end Page editor. Maybe with a plugin you can, but not out of the box.
The easiest solution for this is creating a shortcode. Then you can use something like this
function input_func( $atts ) {
extract( shortcode_atts( array(
'type' => 'text',
'name' => '',
), $atts ) );
return '<input name="' . $name . '" id="' . $name . '" value="' . (isset($_GET\['from'\]) && $_GET\['from'\] ? $_GET\['from'\] : '') . '" type="' . $type . '" />';
}
add_shortcode( 'input', 'input_func' );
See the Shortcode_API.
Answer：
When I was trying to accomplish something very similar, I ended up doing something along these lines:
wp-content/themes/resources/functions.php
add_action('init', 'my_php_function');
function my_php_function() {
if (stripos($_SERVER['REQUEST_URI'], 'page-with-custom-php') !== false) {
// add desired php code here
}
}
