Autocomplete Places Search Box using Google Maps JavaScript API

An autocomplete feature is very useful for the addresses search box. When a user starts typing an address, the autocomplete field list the suggestions based on the search term. You can use the autocomplete input field to search addresses on the web application. The autocomplete places search box can be integrated easily with the Google Maps JavaScript API.

Using Google Maps JavaScript API and Places library, you can easily add an autocomplete places search box to a web page. The Places library provides an autocomplete feature with the Maps JavaScript API. We’ll use HTML and JavaScript to implement places search box with autocomplete address suggestion. In this tutorial, we will show you how to integrate the location search box with autocomplete and display a map marked with selected location and info window using Google Maps JavaScript API.

Google Places Autocomplete In PHP with Example

PHP 8 google address autocompletes without showing the map. In this tutorial, i will show youhow to create a google autocomplete address web app using google address APIs in PHP.

Note that, Google autocomplete address API will return address and as well as latitude, longitude, place code, state, city, country, etc. Using latitude and longitude of address, you can show markers location in google map dynamically in php.

This tutorial guide to you step by step how to implement google places autocomplete address web application without showing google maps in PHP.

For implementing the autocomplete address in php, you will have to get the key from google console app. So, just go to the link https://cloud.google.com and get the google API key.

Seat Reservation With Jquery And Php

Seat Reservation with jQuery

In my Online Bus Reservation System project, I got queries from many people about how to implement seat selection screen effectively. So, I decided to write on it. This post explains how to implement seat booking with jQuery. It can be used in online Bus, flight, hotel, exam support, cinema and ticket booking system.

 

seat reservation jquery

HTML:

<h2> Choose seats by clicking the corresponding seat in the layout below:</h2>

    <div id="holder">

        <ul  id="place">

        </ul>   

    </div>

    <div style="float:left;">

    <ul id="seatDescription">

        <li style="background:url('images/available_seat_img.gif') no-repeat scroll 0 0 transparent;">Available Seat</li>

        <li style="background:url('images/booked_seat_img.gif') no-repeat scroll 0 0 transparent;">Booked Seat</li>

        <li style="background:url('images/selected_seat_img.gif') no-repeat scroll 0 0 transparent;">Selected Seat</li>

    </ul>

    </div>

        <div style="clear:both;width:100%">

        <input type="button" id="btnShowNew" value="Show Selected Seats" />

        <input type="button" id="btnShow" value="Show All" />          

        </div>

We will add seats in “#place” element using javascript.

Settings:

To make it generalize, settings object is used.

var settings = {

               rows: 5,

               cols: 15,

               rowCssPrefix: 'row-',

               colCssPrefix: 'col-',

               seatWidth: 35,

               seatHeight: 35,

               seatCss: 'seat',

               selectedSeatCss: 'selectedSeat',

               selectingSeatCss: 'selectingSeat'

           };

rows: total number of rows of seats.
cols: total number of seats in each row.
rowCssPrefix: will be used to customize row layout using (rowCssPrefix + row number) css class.
colCssPrefix: will be used to customize column using (colCssPrefix + column number) css class.
seatWidth: width of seat.
seatHeight: height of seat.
seatCss: css class of seat.
selectedSeatCss: css class of already booked seats.
selectingSeatCss: css class of selected seats.

Seat Layout:

We will create basic layout of seats.

var init = function (reservedSeat) {

                var str = [], seatNo, className;

                for (i = 0; i < settings.rows; i++) {

                    for (j = 0; j < settings.cols; j++) {

                        seatNo = (i + j * settings.rows + 1);

                        className = settings.seatCss + ' ' + settings.rowCssPrefix + i.toString() + ' ' + settings.colCssPrefix + j.toString();

                        if ($.isArray(reservedSeat) && $.inArray(seatNo, reservedSeat) != -1) {

                            className += ' ' + settings.selectedSeatCss;

                        }

                        str.push('<li class="' + className + '"' +

                                  'style="top:' + (i * settings.seatHeight).toString() + 'px;left:' + (j * settings.seatWidth).toString() + 'px">' +

                                  '<a title="' + seatNo + '">' + seatNo + '</a>' +

                                  '</li>');

                    }

                }

                $('#place').html(str.join(''));

            };

            //case I: Show from starting

            //init();

            //Case II: If already booked

            var bookedSeats = [5, 10, 25];

            init(bookedSeats);

 

init method is used to draw seats layout. Already booked seats array will be passed as argument of this method.

Seat Selection:

?

$('.' + settings.seatCss).click(function () {

if ($(this).hasClass(settings.selectedSeatCss)){

    alert('This seat is already reserved');

}

else{

    $(this).toggleClass(settings.selectingSeatCss);

    }

});

$('#btnShow').click(function () {

    var str = [];

    $.each($('#place li.' + settings.selectedSeatCss + ' a, #place li.'+ settings.selectingSeatCss + ' a'), function (index, value) {

        str.push($(this).attr('title'));

    });

    alert(str.join(','));

})

$('#btnShowNew').click(function () {

    var str = [], item;

    $.each($('#place li.' + settings.selectingSeatCss + ' a'), function (index, value) {

        item = $(this).attr('title');                  

        str.push(item);                  

    });

    alert(str.join(','));

})

When user clicks on available seat, it is selected and second click on same seat will unselect seat. Button “Show All” will show all booked seat numbers and “Show Selected Seats” will show selected seats only.

CSS:

?

#holder{   

height:200px;   

width:550px;

background-color:#F5F5F5;

border:1px solid #A4A4A4;

margin-left:10px;  

}

#place {

position:relative;

margin:7px;

}

#place a{

font-size:0.6em;

}

#place li

{

 list-style: none outside none;

 position: absolute;  

}   

#place li:hover

{

background-color:yellow;     

}

#place .seat{

background:url("images/available_seat_img.gif") no-repeat scroll 0 0 transparent;

height:33px;

width:33px;

display:block;  

}

#place .selectedSeat

{

background-image:url("images/booked_seat_img.gif");         

}

#place .selectingSeat

{

background-image:url("images/selected_seat_img.gif");       

}

#place .row-3, #place .row-4{

margin-top:10px;

}

#seatDescription li{

verticle-align:middle;   

list-style: none outside none;

padding-left:35px;

height:35px;

float:left;

}

In my next post, you will get how to use this in asp.net project with sql server database .

Pdf2gerb: Perl Script Converts PDF Files to Gerber format

pdf2gerb

Perl script converts PDF files to Gerber format

Pdf2Gerb generates Gerber 274X photoplotting and Excellon drill files from PDFs of a PCB. Up to three PDFs are used: the top copper layer, the bottom copper layer (for 2-sided PCBs), and an optional silk screen layer. The PDFs can be created directly from any PDF drawing software, or a PDF print driver can be used to capture the Print output if the drawing software does not directly support output to PDF.

The general workflow is as follows:

  1. Design the PCB using your favorite CAD or drawing software.
  2. Print the top and bottom copper and top silk screen layers to a PDF file.
  3. Run Pdf2Gerb on the PDFs to create Gerber and Excellon files.
  4. Use a Gerber viewer to double-check the output against the original PCB design.
  5. Make adjustments as needed.
  6. Submit the files to a PCB manufacturer.

Please note that Pdf2Gerb does NOT perform DRC (Design Rule Checks), as these will vary according to individual PCB manufacturer conventions and capabilities. Also note that Pdf2Gerb is not perfect, so the output files must always be checked before submitting them. As of version 1.6, Pdf2Gerb supports most PCB elements, such as round and square pads, round holes, traces, SMD pads, ground planes, no-fill areas, and panelization. However, because it interprets the graphical output of a Print function, there are limitations in what it can recognize (or there may be bugs).

See docs/Pdf2Gerb.pdf for install/setup, config, usage, and other info.

Google Maps Draggable Marker Get Coordinates

In this blog post, you will learn how to create google maps draggable marker using Google Maps Javascript API v3, and when you drag the marker position then get coordinates (latitude and longitude) of that location where you place the marker.

How to make a marker draggable?

To allow users to drag a marker to a different location on the map, set the draggable attribute to true in the marker options.

var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {
  zoom: 4,
  center: myLatlng
}
var map = new google.maps.Map(document.getElementById("map"), mapOptions);
// Place a draggable marker on the map
var marker = new google.maps.Marker({
    position: myLatlng,
    map: map,
    draggable:true,
    title:"Drag me!"
});
