Getting the bounds of a polyine in Google Maps API v3 -

April 15, 2015

Is there any easy way to find a polyline's bounding box while using Google Maps API V3? I am working on the project where I need to update the data and has been removed from the map. It's just so easy to do bd.extend (point), where BD is a bound object and a pointing layer object. The problem occurs when I start deleting the data, I would like to change the boundary and zoom in again. Is there any functions that can do this or will I need to write something for myself?

There was absolutely no way to do this. However it appears that there is no equivalent method in it.

You can handle it by overriding the property of your Polyline MVCObject and it will be notified when the item changes. You can then calculate the boundary box using the method recommended by you.

  I think Google had deliberately left such methods with the v3 API in an effort to keep the API lightweight. There was a similar lapse method.

Short URL Outbound Link Tracking in PHP and MySQL -



    I have a site that reduces the link based on this topic. I decided that it would be great if users click on a small URL, like HootSuite users can track their links. I currently have a database in which the short URL is placed with the actual URL and this click count will ideally update the click count column when that small URL is accessed by an external user.   In short, I am looking for a PHP / MySQL solution so that many small URLs can be clicked. . Any additional information gathered from the clicks will also be highly appreciated.      I'm assuming you followed the PHP version of your tutorial. If so, look at listing for service.php under "service of small URL". In section round line 11 where it determines the position of 301, you can redirect with the database update. Something like    $ query = mysql_query ("update`" $ database. "` .```_AL_DIRED`Set count = count + 1 where` small '=' ".mysql_escape_string ($ short) , $ Db); $ Line = ...

php - How do I set up pagination for an image gallery with image
thumbnails? -



    I have two tables:    gallery id | Name | Details Image ID | Title | Caption | Gallery ID    By listing all thumbnails or paging through thumbnails I got the code to create a simple image gallery. However, what I need to do is here something like gallery here Only completes without javascript and ajax:     I want a selection number to show below the main image as soon as the user clicks the thumbnail, the page Selected new Highlight the image and the series of thumbnails on boto goes forward one by one if its not the last image.   How do I do this? Do I need a quick and dirty way to do this? I am using php and mysql for the database here - just need code to show 'paged' images below the main image. I know how to install everything i.e. Thumbnail size etc ...      I do not know the number of your rows in MySQL for T-SQL As there is a ROWNUMBER () function, but to do this, it is a smart way to sequential numbering of your images in the database. From there, you ask something ...
