README

PHPSearchController is a simple PHP class to search MySQL database, it can build SQL queries to perform MySQL database searches by taking parameters that define database table fields and field values to search.

The class generates SQL conditions used to build SQL queries to perform database searches for records that match the criteria based on the table fields and field values defined by the parameters, It then combines several conditions using SQL operators such as AND, OR, NAND, LIKE NOR & FIND_IN_SET and return the appropriate queries for the search.

Installation

Installation is super-easy via Composer:

composer require peterujah/php-search-controller

Usages

Initialize the class with your preferred search method the default method is SearchController::OR.

use Peterujah\NanoBlock\SearchController;
$search = new SearchController();

Set your preferred search operator the default is SearchController::END_WITH_QUERY.

$search->setOperators(SearchController::HAVE_ANY_QUERY);

To perform a database search, you can just build your search query like the one below.

$searchQuery = "PHP Code";
$search->setQuery($searchQuery)->split();
$search->setParameter(array(
    'code_title', 
    'code_description', 
    'code_info'
));
//var_export($search->getQuery());

To search by tag using MySQL FIND_IN_SET, build a query like the example below.

$searchQuery = "PHP Code";
$search->setQuery($searchQuery)->split();
$search->setTags("code_tags");
//var_export($search->getQuery());

Set the initial query and pass the search query to your MySQL connection

$search->setIniQuery("SELECT * FROM code WHERE id = 1323");
$db->conn()->prepare($search->getQuery());
$db->conn()->execute();		
$result = $db->conn()->getAll();
$db->conn()->free();

OR build it with other sql queries like the below in your MySQL connection

$db->conn()->prepare("
    SELECT * FROM code 
    {$search->getQuery()}
    AND id = 1323
");
$db->conn()->execute();		
$result = $db->conn()->getAll();
$db->conn()->free();

Other Methods

Returns the computed sql search queries by checking if the initial query was specified or not to determine which start clause is needed.

$search->getQuery()

Set your search keyword

$search->setQuery("Foo Bar")

Split search keyword Foo Bar into Foo, Bar as separate search terms

$search->split()

Mapping your database column keys to perform a search on

$search->setParameter(array)

Set the initial SQL query before appending the search after your query string

$search->setIniQuery('SELECT * FROM ...')

Reference

Specify search operator $search->setOperators(SearchController::HAVE_ANY_QUERY)

Initialize search class with a method new SearchController(SearchController::OR)
