A major problem people have in designing / creating forms is to decide whether to use the GET or POST methods. GET: ----- 1. URL Changes to the submitted script name, appended with a list of each variable with the value. 2. Use only if the number of variable to be used in a form ar very less. 3. Never use GET forms when asking for login ID and passwords. 4. Even hidden variables are shown as a part of the URL. 5. A lot of webservers might complain about long URLs being submitted. A lot of times a URL 255 char or more is a problem. POST: ----- 1. This is the best way of submitting forms to the web server. 2. There is no limitation on the number of Variables passed from the form. 3. This is a transparent way of transmitting variables to the webserver where hidden variable are always hidden! Usage Example
Once the form is submitted, the URL will show as below: http://www.mywebsite.com/tests/testform.phtml? id=101&userselected=ProcessNow&userselected.x=130&userselected.y=42 Notice how the 'id' is shown as a part of the URL. This is not always what you might have wanted. So, here the length of the URL should not be > 255 characters for it to be processed properly by all webservers. Usage Example
Once the form is submitted, the URL will still show: http://www.mywebsite.com/tests/testform.phtml while the form variable id and userselected will be passed to the server transparently. | ||||||||||||||||
