Vill du integrera DataTable i din applikation? DataTable l\u00e4gger till avancerade interaktionskontroller i dina HTML-tabeller. Dessutom \u00e4r den \u00f6ppen k\u00e4llkod s\u00e5 att alla kan anv\u00e4nda den gratis. Det \u00e4r anv\u00e4ndbart n\u00e4r din tabell har hundratals poster. Med hj\u00e4lp av DataTable f\u00e5r du deras inbyggda funktioner som sortering, s\u00f6kning, paginering etc. I den h\u00e4r artikeln visar jag dig hur du anv\u00e4nder DataTable i PHP.<\/p>\n

DataTables<\/a> \u00e4r ett popul\u00e4rt val f\u00f6r att lista tabellposter i applikationen. P\u00e5 grund av sin enkelhet och enkla installation f\u00f6redrog utvecklare att anv\u00e4nda den.<\/p>\n

F\u00f6r v\u00e5r handledning skapar jag en tabell i databasen och visar dess poster i datatabellen. Den slutliga utdata kommer att se ut som nedan sk\u00e4rmdump:<\/p>\n

Komma ig\u00e5ng<\/h3>\n

F\u00f6r att komma ig\u00e5ng, g\u00e5 \u00f6ver till din phpMyAdmin och skapa tabellen med hj\u00e4lp av nedanst\u00e5ende fr\u00e5ga:<\/p>\n

CREATE TABLE `users` (\u00a0`id` int(11) NOT NULL AUTO_INCREMENT,\n\u00a0`first_name` varchar(255) NOT NULL,\n\u00a0`last_name` varchar(255) NOT NULL,\n\u00a0`age` int(11) NOT NULL,\n\u00a0PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=latin1;<\/code><\/pre>\n
Tabellen ’anv\u00e4ndare’ har kolumner f\u00f6rnamn, efternamn och \u00e5lder. L\u00e4gg till dummy-poster i denna tabell. Anv\u00e4ndaren kan anv\u00e4nda Faker-biblioteket f\u00f6r<\/a> att uts\u00e4ta din tabell med dummy-poster. Med hj\u00e4lp av faker-biblioteket kan man l\u00e4gga till tusentals falska poster i databasen inom n\u00e5gra \u00f6gonblick.<\/p>\n
Skapa sedan en config.php<\/code>fil och skriv en kod f\u00f6r databasanslutning.<\/p>\n
config.php<\/strong><\/p>\n
<?php\n$conn = new mysqli(DB_HOST, DB_USERNAME, DB_PASSWORD, DB_NAME);\n\u00a0\nif ($conn->connect_errno) {\n\u00a0\u00a0\u00a0\u00a0echo \"Error: \". $conn->connect_error;\n}<\/code><\/pre>\n
Se till att ers\u00e4tta platsh\u00e5llarna med de faktiska v\u00e4rdena.<\/p>\n
Hur man anv\u00e4nder DataTable i PHP<\/h3>\n
Att integrera DataTable vad jag ska g\u00f6ra \u00e4r att h\u00e4mta poster fr\u00e5n databasen, slinga igenom den och visa den i en tabell. Och anv\u00e4nd sedan DataTable i HTML-tabellen.<\/p>\n
Skapa en index.php<\/code>fil och l\u00e4gg till koden nedan i den.<\/p>\n
<?php\nrequire_once('config.php');\n\u00a0\n$sql = \"SELECT id, first_name, last_name, age FROM users\";\n$result = $conn->query($sql);\n$arr_users = [];\nif ($result->num_rows > 0) {\n\u00a0\u00a0\u00a0\u00a0$arr_users = $result->fetch_all(MYSQLI_ASSOC);\n}\n?><\/code><\/pre>\n
I ovanst\u00e5ende kod h\u00e4mtade jag alla rader fr\u00e5n tabellen ’anv\u00e4ndare’ och tilldelade dem till PHP-variabeln $arr_users<\/code>. Nu kommer jag att g\u00e5 igenom denna variabel och skapa tabellraden en efter en.<\/p>\n
