I haven't officially started learning PHP just skimming through a couple tutorials and I have a question. Why would some one choose to use Get vs Post? Why would you ever want the data shown in the url bar? I understand post is used for passwords and important info but I don't understand why you would use get instead of just post all the time?
Thanks for any insight.
$_GET is useful for pages where users are requesting data - such as a search page, and pages that a user might want to bookmark and share with others. readonly
$_POST is useful for pages where users are "posting" data - such as a signup form. $_POST should be used when you don't want your visitors to be able to bookmark page. read/write
As prodigitalson added: you may use $_POST or $_GET for any operation, but it is good practice to use them as described above.
If you want people to be able to share the link with their friends...for eg http://yoursite.com/products.php?product_id=12
Some times you have to pass params(data) to a script without form submit OR want to share that script to someone. In that case $_GET is useful.
GET method may result in long URLs, and may even exceed some browser and server limits on URL length.
GET requests are idempotent. POST requests change server state.
This is an HTTP question, not a PHP question.
are you planning to fill your website with forms and buttons on each link?? every link you see in this site is sending GET variables.. maybe your question is related to the "method" attribute in a form, if that's the case, well 90% of the cases post is a better choice dont worry about the security :) just because you dont see the information in the navigation bar doesnt mean that its secured, watching the information sent by post is only two clicks away ;)
