Autocomplete Remote DataSource Example with PHP MySQL Live Auto Suggestion

Database / Table

following is the sample database and table named 'tbl_posts' with dumping data contains post title, and post url, so just copy paste this sql code into your phpMyAdmin.

--



-- Database: `codingcage`



--








-- --------------------------------------------------------








--



-- Table structure for table `tbl_posts`



--








CREATE TABLE IF NOT EXISTS `tbl_posts` (



  `postID` int(11) NOT NULL AUTO_INCREMENT,



  `postTitle` varchar(255) NOT NULL,



  `postUrl` varchar(255) NOT NULL,



  PRIMARY KEY (`postID`)



) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=11 ;




--



-- Dumping data for table `tbl_posts`



--








INSERT INTO `tbl_posts` (`postID`, `postTitle`, `postUrl`) VALUES

Database Connection

well, i don't need to explain this code, this is 'dbconfig.php' file.

<?php



 



 $DBhost = "localhost";



 $DBuser = "root";



 $DBpass = "";



 $DBname = "codingcage";



 



 try {



  $DBcon = new PDO("mysql:host=$DBhost;dbname=$DBname",$DBuser,$DBpass);



 } catch(PDOException $ex){



  die($ex->getMessage());



 }

Server-Side Script / Post_search.Php

this file is for getting suggestion from 'tbl_posts' and works silently behind the scene, whenever user types in search box this file will get triggered and will return JSON format. and that JSON data will be shown as a auto suggestion.

<?php




 require_once 'dbconfig.php';




 $keyword = trim($_REQUEST['term']); // this is user input








 $sugg_json = array();    // this is for displaying json data as a autosearch suggestion



 $json_row = array();     // this is for stroring mysql results in json string



 



 $keyword = preg_replace('/\s+/', ' ', $keyword); // it will replace multiple spaces from the input.








 $query = 'SELECT postID, postTitle, postUrl FROM tbl_posts WHERE postTitle LIKE :term'; // select query



 



 $stmt = $DBcon->prepare( $query );



 $stmt->execute(array(':term'=>"%$keyword%"));



 



 if ( $stmt->rowCount()>0 ) {



  



  while($recResult = $stmt->fetch(PDO::FETCH_ASSOC)) {



      $json_row["id"] = $recResult['postUrl'];



      $json_row["value"] = $recResult['postTitle'];



      $json_row["label"] = $recResult['postTitle'];



      array_push($sugg_json, $json_row);



  }



  



 } else {



     $json_row["id"] = "#";



     $json_row["value"] = "";



     $json_row["label"] = "Nothing Found!";



     array_push($sugg_json, $json_row);



 }



 



 $jsonOutput = json_encode($sugg_json, JSON_UNESCAPED_SLASHES); 



 print $jsonOutput;

Of course, you will need jQuery UI libraries here is that.


<link rel="stylesheet" href="http://code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">



<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>

Search Box

Simple search form created with bootstrap just to give pretty look, 

<div class="col-lg-offset-2">



<form>



<div class="form-group">



<div class="input-group">



<input id="txtSearch" class="form-control input-lg" type="text" placeholder="Search for PHP, MySQL, Ajax and jQuery" />



<div class="input-group-addon"><i class="glyphicon glyphicon-search"></i></div>



</div>



</div>



</form>  



</div>

JavaScript / AutoComplete JQuery Code

this is the main JavaScript code which makes a search box more dynamic, with the help of .autocomplete({}) function we can achieve autocomplete functionality with the just few lines of code. #txtSearch is the id of search input field.

$(document).ready(function(){



 



 $('#txtSearch').autocomplete({



     source: "post_search.php",



     minLength: 2,



     select: function(event, ui) {



         var url = ui.item.id;



         if (url != '#') {



             location.href = url



         }



     },



     open: function(event, ui) {



         $(".ui-autocomplete").css("z-index", 1000)



     }



 })



 



});

Custom CSS

I have customized the default look of autocomplete widget, you can check that in live demo. this is style.css file so create this one by copy pasting this following css code.

form .form-group{



   width: 700px;



   max-width: 100%;



   border-radius: 0 !important;



}



* {



  -webkit-border-radius: 0 !important;



     -moz-border-radius: 0 !important;



          border-radius: 0 !important;



}



.ui-autocomplete {



    max-height: 300px;



    overflow-y: auto;



    /* prevent horizontal scrollbar */



    overflow-x: hidden;



}



* html .ui-autocomplete {



    height: 300px;



}




.ui-autocomplete .ui-menu-item-wrapper {



    font-size: 15px;



    border-radius: 0;



    border-bottom: solid #eceff1 2px;



    padding: 10px;



    color: #000;



    background: #f9f9f9;



}



.ui-autocomplete .ui-menu-item {



    color: #000;



    background: #f9f9f9;



}




.ui-autocomplete .ui-menu-item:hover, .ui-menu-item-wrapper:hover {



    color: #fff;



    background: #a8a9d0;



}




.ui-menu .ui-state-focus,



.ui-menu .ui-state-active {



 color: #fff;



    background: #967cfc;



    background: #a8a9d0;



    border: 0;



}
