Answer 1

If you want to do search with all fields add fields in WHERE with OR:
try {
$keyword = trim($_GET["keyword"]);
if ($keyword <> "" ) {
$sql = "SELECT * FROM tbl_contacts WHERE 1 AND "
. " (first_name LIKE :keyword OR last_name LIKE :keyword OR middle_name LIKE :keyword OR contact_no1 LIKE :keyword) ORDER BY first_name ";
$stmt = $DB->prepare($sql);
$stmt->bindValue(":keyword", $keyword."%");
} else {
$sql = "SELECT * FROM tbl_contacts WHERE 1 ORDER BY first_name ";
$stmt = $DB->prepare($sql);
}

public function search($requestArray){
$sql = "";
if( isset($requestArray['firstname']) && isset($requestArray['lastname']) ) $sql = "SELECT * FROM `tbl_contacts` WHERE AND (`first_name` LIKE '%".$requestArray['search']."%' OR `last_name` LIKE '%".$requestArray['search']."%')";
if(isset($requestArray['firstname']) && !isset($requestArray['lastname']) ) $sql = "SELECT * FROM `tbl_contacts` WHERE `first_name` LIKE '%".$requestArray['search']."%'";
if(!isset($requestArray['firstname']) && isset($requestArray['lastname']) ) $sql = "SELECT * FROM `tbl_contacts` WHERE `last_name` LIKE '%".$requestArray['search']."%'";
$STH = $this->DBH->query($sql);
$STH->setFetchMode(PDO::FETCH_OBJ);
$someData = $STH->fetchAll();
return $someData;
}
I used this method in one of my project for searching with two field hope it could help you. where $requestArray will get the data from form and 'firstname' , 'lastname' are two key of the array which you will enter your searchbox and submit to search. I just showed you here the query style and before that you have tor trim the values.
