something like this

if(is_valid_uk_postcode($strSearch) == TRUE)) {
//use code or message for when is good
echo 'Valid postcode';
} else {
//do something else with it
echo 'Invalid postcode';
}

going by how you are using this in your code, I guess something like this could work

if((!isset($_POST['strSearch'])) || (strlen(trim($_POST['strSearch'])) <5) || (trim($_POST['strSearch']) != preg_replace("/[^a-zA-Z0-9\_]/", "", trim($_POST['strSearch'])))) {
$error_message = "You must enter a valid postcode<br>";
$error_message = $error_message . "Valid postcodes must not contain and spaces and consist of letters and numbers only.<br>";
$error_message = $error_message . 'Your invalid name was: <font color="red">' . $_POST['strSearch'] . "</font><hr>";
}else{
$postcode = mysql_real_escape_string(trim($_POST['strSearch']));

if(is_valid_uk_postcode($postcode) == FALSE)) {
exit("Invalid postcode");
}

}

or just do the error message as you did others, and add this check to this line as so

if((!isset($_POST['strSearch'])) ||  is_valid_uk_postcode(trim($_POST['strSearch']))) == FALSE  || (strlen(trim($_POST['strSearch'])) <5) || (trim($_POST['strSearch']) != preg_replace("/[^a-zA-Z0-9\_]/", "", trim($_POST['strSearch'])))) {
