integrete google route planner in php

By -
Hi friends,

Here you can get how to integrate a route planner to your website. You first need a google map key to your website.


The http://maps.google.com/maps?file=api&v=2&key=abcdefg URL points to the location of the JavaScript file that includes all of the symbols and definitions you need for using the Google Maps API. Your page must contain a script tag pointing to this URL, using the key you received when you signed up for the API. In this example the key is shown as "abcdefg."


Loading the Map

 onload="initialize()" onunload="GUnload()">
The onload attribute is an example of an event handler.
map.addControl(new GSmallMapControl());
map.addControl(new GMapTypeControl());
map.enableDoubleClickZoom();
The enableDoubleClickZoom() gives the functionality of double click zoom on map.  

 setDirections("Noida", "Agra", "en_US");
The setDirections() takes 3 parameter from, to, locale, . 


The full code here

Drupal Bootstrap Database

By -
This is the 3rd article in the series covering DRUPAL v6 bootstrap process. As the bootstrap name implies, this phase covers initializing a connection to a database. The phase begins by including 'database.inc' , which is a database abstraction layer allowing developers to use different database servers with the same code base. One of the functions defined by this library is the db_set_active() function, which is invoked by the bootstrap database phase. This function is used to activate a database used by queries in later phases or during page building and rendering. The function begins by checking if the global variable $db_url is empty. Recall that in the phase #1 - DRUPAL_BOOTSTRAP_CONFIGURATION, this variable is set to the value specified in settings.php unless it is still set to the default string of ' mysql://username:password@localhost/databasename' . In that case, $db_url is simply set to empty string ''. This would indicate a first time insta...

How to fix 500 internal privoxy error

By -
I keep getting a 500 Internal Privoxy Error when I open a particular URL. I t ried several websites that promise a fix but only want to sell me some bullshit software for $29.95 that doesn't do anything.   The actual message is as follows 500 Internal Privoxy Error Privoxy encountered an error while processing your request: Could not load template file connect-failed or one of its included components. Please contact your proxy administrator. If you are the proxy administrator, please put the required file(s)in the (confdir)/templates directory. The location of the (confdir) directory is specified in the main Privoxy config file. (It's typically the Privoxy install directory). After spending so much of time and putting lots of effort at internet, finally I fixed it. The solutions is -- Disable proxy settings and check. Press “Windows Logo” + “R” keys on the keyboard, type “inetcpl.cpl” and press “Enter”. Click the “Connections” tab, and then click “LAN settings...
