Creating Advance Search Condition in PHP This code receives form inputs and forms MySQL query with the advanced search condition. If the user prefers database columns to search then the search will apply on that column. Otherwise, we will search in all the columns. The code is,
$v) < if(!empty($v)) < $queryCases = array("with_any_one_of","with_the_exact_of","without","starts_with"); if(in_array($k,$queryCases)) < if(!empty($queryCondition)) < $queryCondition .= " AND "; >else < $queryCondition .= " WHERE "; >> switch($k) < case "with_any_one_of": $with_any_one_of = $v; $wordsAry = explode(" ", $v); $wordsCount = count($wordsAry); for($i=0;$i<$wordsCount;$i++) < if(!empty($_POST["search"]["search_in"])) < $queryCondition .= $_POST["search"]["search_in"] . " LIKE '%" . $wordsAry[$i] . "%'"; >else < $queryCondition .= "title LIKE '" . $wordsAry[$i] . "%' OR description LIKE '" . $wordsAry[$i] . "%'"; >if($i!=$wordsCount-1) < $queryCondition .= " OR "; >> break; case "with_the_exact_of": $with_the_exact_of = $v; if(!empty($_POST["search"]["search_in"])) < $queryCondition .= $_POST["search"]["search_in"] . " LIKE '%" . $v . "%'"; >else < $queryCondition .= "title LIKE '%" . $v . "%' OR description LIKE '%" . $v . "%'"; >break; case "without": $without = $v; if(!empty($_POST["search"]["search_in"])) < $queryCondition .= $_POST["search"]["search_in"] . " NOT LIKE '%" . $v . "%'"; >else < $queryCondition .= "title NOT LIKE '%" . $v . "%' AND description NOT LIKE '%" . $v . "%'"; >break; case "starts_with": $starts_with = $v; if(!empty($_POST["search"]["search_in"])) < $queryCondition .= $_POST["search"]["search_in"] . " LIKE '" . $v . "%'"; >else < $queryCondition .= "title LIKE '" . $v . "%' OR description LIKE '" . $v . "%'"; >break; case "search_in": $search_in = $_POST["search"]["search_in"]; break; > > > > $orderby = " ORDER BY id desc"; $sql = "SELECT * FROM links " . $queryCondition; $result = mysqli_query($conn,$sql); ?> Database Script with Structure and Data of the MySQL table This database script is used to import the links table structure and the data to run this example PHP code.

PHP MySql Advanced Search Feature In this article, you will learn how to develop an advanced search feature using PHP and MySQL .
The advanced search feature provides more search options for users to filter the search results. When used for searching the Web, an advanced search gives additional information and search query filter options to the user, which helps refine the search and allows the user to find the exact information that they are looking for. A normal search is not relevant when the search query returns too many records. It will become a hectic task for the user to find out exactly what they want. That’s why we are using advanced search.
Here, we have taken an example of a tourism search filter. For this, we first created two MySQL tables named ‘tourist_city ‘ and ‘visiting_places ‘ and inserted some records into them. You can use the database if you already have otherwise, you can create it manually or copy and paste the following queries into your database.
CREATE TABLE IF NOT EXISTS `tourist_city` ( `city_id` int(11) NOT NULL AUTO_INCREMENT, `city` varchar(100) NOT NULL, `is_enabled` int(11) NOT NULL, PRIMARY KEY (`city_id`) ) CREATE TABLE IF NOT EXISTS `visiting_places` ( `vid` int(11) NOT NULL AUTO_INCREMENT, `city_id` int(11) NOT NULL, `visiting_place` varchar(100) NOT NULL, `history` varchar(1000) NOT NULL, `is_enabled` int(11) NOT NULL, PRIMARY KEY (`vid`) ) INSERT INTO `tourist_city` (`city_id`, `city`, `is_enabled`) VALUES (1, 'Delhi', 1), (2, 'Mumbai', 1), (3, 'Goa', 1), (4, 'kolkata', 1); INSERT INTO `visiting_places` (`vid`, `city_id`, `visiting_place`, `history`, `is_enabled`) VALUES (1, 1, 'Red Fort', 'The Red Fort was the residence of the Mughal emperor for nearly 200 years, until 1857. It is located in the centre of Delhi and houses a number of museums. In addition to accommodating the emperors and their households, it was the ceremonial and political centre of Mughal government and the setting for events critically impacting the region.[', 1), (2, 1, 'Lotus Temple', 'The Lotus Temple, located in New Delhi, India, is a Bahai House of Worship completed in 1986. Notable for its flowerlike shape, it serves as the Mother Temple of the Indian subcontinent and has become a prominent attraction in the city', 1), (3, 2, 'Gateway of India', 'The Gateway of India is a monument built during the 20th century in Mumbai City of Maharashtra state in Western India.', 1), (4, 2, 'Elephanta Caves', 'Elephanta Caves are a network of sculpted caves located on Elephanta Island, or Gharapuri (literally "the city of caves") in Mumbai Harbour, 10 kilometres (6.2 mi) to the east of the city of Mumbai in the Indian state of Maharashtra.', 1), (5, 3, 'Marine Drive', 'Marine Drive is a 3.5-kilometre-long boulevard in South Mumbai in the city of Mumbai. It is a ''C''-shaped six-lane concrete road along the coast, which is a natural bay. ', 1), (6, 3, 'Fort Aguada', 'The fort was constructed in 1612 to guard against the Dutch and the Marathas. It was a reference point for the vessels coming from Europe at that time.', 1), (7, 4, 'Victoria Memorial', 'The Victoria Memorial is a large marble building in Kolkata (formerly Calcutta), West Bengal, India, which was built between 1906 and 1921.', 1), (8, 4, 'Dakhshineswar Tample', 'The Victoria Memorial is a large marble building in Kolkata (formerly Calcutta), West Bengal, India, which was built between 1906 and 1921.', 1); 1. db.php Here, we have written the database connection code and defined functions to fetch data from the created tables. The function ‘getVisitinPlaceData()’ returns the data of search results. Make sure to replace the ‘hostname ‘, ‘username ‘, ‘password ‘, and ‘database ‘ with your database credentials.
class Db < private $hostname = 'hostname'; private $username = 'username'; private $password = 'password'; private $database = 'database'; private $conn = NULL ; public function __construct() < $this ->conn = mysqli_connect ($this ->hostname, $this ->username, $this ->password, $this ->database); if(!$this ->conn) < echo 'Database not connected'; >> public function getTouristCity ()< $query = "SELECT * FROM tourist_city WHERE is_enabled = '1'"; $result = mysqli_query ($this ->conn, $query ); return $result ; > public function getVisitingPlaces ()< $query = "SELECT * FROM visiting_places WHERE is_enabled = '1'"; $result = mysqli_query ($this ->conn, $query ); return $result ; > public function getVisitinPlaceData ($cityid , $placeid , $keyword )< $sWhere = ''; $where = array() ; if ($cityid > 0) < $where [] = 'V.city_id = '.$cityid .' AND V.is_enabled = "1"'; > if ($placeid > 0) < $where [] = 'V.vid = '.$placeid ; > if ($keyword != '') < $keyword = trim ($keyword ); $where [] color: #0000ff;">$keyword %' OR V.history LIKE '%$keyword %' OR C.city LIKE '%$keyword %' )"; > $sWhere = implode(' AND ', $where ); if ($sWhere ) < $sWhere = 'WHERE '.$sWhere ; > if (($cityid > 0) || ($placeid > 0) || ($keyword != '')) < $query color: #0000ff;">$sWhere "; $result = mysqli_query ($this ->conn, $query ); return $result ; > > > ?> 2. index.php This is the main file that we will call in the browser. In this file, we have written an HTML form to search for data. When a user clicks on the ‘Search ‘ button, the form gets submitted, and the search results are displayed.
