In web development it is very normal that we create 'Contact-Us' Form . And we want to send complete form submitted data in a mail to somebody (normally to ourself ).
There are many ways to do this .1) using javascript
2) using any server side scripting like PHP .
First way -- javascript -->
As we know javascript is client side scripting , so it need a client to send mail i.e. mail client .
Example :-
lets take a simple form .
form.html
This is simplest example . If we try to see what happens here , we are using javascript "mailto" function . "mailto" will trigger mail client to send mail that means , it will call you MS-Outlook (if installed and configured ) .This way is not used widely as it is client dependent way and we don't have any control here .
Second way -- server side scripting e.g. PHP -->
php will need a mail server configured to send a mail . As we are developers we can control and configure mail server by our own .
Example :-
form.html
abc.php
Now this is stable and trusted code to send mails . And everyone should use this way of sending mail .
There are two ways of submitting form i.e. GET and POST . Both methods have their importances .
If we submit form using get method and then all data submitted will be append in the action page url . And we know that url have its limits so we can send only small amount of data using GET method .
While in POST method data is sent in the request body so there is no limit here to send data .
Also in GET method data is visible in th url , so it is not safe . Whenever we need to create safe application we should use POST method .
GET method is fast as everything is simply appended in the url . But in using POST method every request need to maintain data in the body . So it is lsightly time consuming method .
Both methods are useful . So we need to choose wisely according to our application taht which method we should use .
Thank you .
