Beginner PHP Tutorial - 70 - Working with $_POST Variables

[@emojimovie2788]

Thanks to these tutorials and my book I managed to create an actual online dictionary. It isn't too professional, but it works.

[@camelCaseFTW]

way to incorporate real life situations into example - really helps :P

@LetsSpotIt Yes I think the the php block will be executed as soon as you load the page. But when the variable is not set the IF will skip everything. And since in your form action you put index.php then the page will be executed and loaded as soon as you submit the form. But this time the variables are set and so you will enter the IF block.

[@capaneo]

@ndm250 I think the isset is just trying to make sure the form is submitted before running the rest of the If statement in php. If you remove that line your PHP code will run as soon as you load the page. Im not sure but I think this is what its looking for

[@jphilfiker]

i am pretty sure he will cover security when he starts connecting to databases, myslq injection and html injection both needed to be checked, but its actually pretty easy.

[@austinch]

@Muse94Muse so that the first time you visit the site it says "Please enter a password" and not "That is incorrect"

[@sharksrinath]

Is using action ='#' is same as action="index.php' where i'm using index.php which is the script where i'm using the form. Does using '#' create any problem? is it recommended?

[@LetsSpotIt]

@capaneo so when you put ?php block before form block, when submitting the form, will the file be executed again and the whole page refreshed?

ANOTHER GOOD THING IS THAT $_GET is better for signing up and $_POST is better for logging in.

[@NikIvRu]

sometimes you need both GET and POST in one form but that's more advanced.

[@Killow]

I don't understand the use of the first line of code "if (isset($_POST['password'])) {... If I comment it out, it also works pretty well... What's the use?

[@DanA-st2ed]

it checks if the field named 'password' in the html form has been submitted correctly.

[@Colstonewall]

From roseindiaDOTnet: "Request of get method can be bookmarked, can be cached, are faster and have known consequences, so visiting them multiple times is not a problem."

[@danutz0501]

You use get for navigation or a search engine. You use post for forms submisions. How to make a pagination system without a get variable for starting the limit in the sql query. Start using session for pagination or how :)))))))))))))))))

[@RahilWazirAli]

POST: variables that you declared in your php page will not be shown on address bar and good for security reasons. while GET: do and not good for security reason

[@Brauseoimel]

He said that there has been an security tutorial relating to forms... did i skip it? does it exist? i cant find it :/

[@Mental1993]

So, we could always use POST and never worry about security and staff?

[@melanshrestha6331]

where do we use GET instead of POST and vice versa?

[@namelast-name616]

GET would be good i think for search engine or something like that and POST most likely for any other thing

[@daniyalyousaf160]

Where to use GET? Information sent from a form with the GET method is visible to everyone (all variable names and values are displayed in the URL). GET also has limits on the amount of information to send. The limitation is about 2000 characters. However, because the variables are displayed in the URL, it is possible to bookmark the page. This can be useful in some cases. GET may be used for sending non-sensitive data. Note: GET should NEVER be used for sending passwords or other sensitive information! When to use POST? Information sent from a form with the POST method is invisible to others (all names/values are embedded within the body of the HTTP request) and has no limits on the amount of information to send. Moreover POST supports advanced functionality such as support for multi-part binary input while uploading files to server. However, because the variables are not displayed in the URL, it is not possible to bookmark the page

[@TheGuroguro12]

Thank you very much

[@TakingItCasual]

Why the dislike? I saw nothing wrong here, he even introduced a new input type; passwords.

[@007hansen]

He isn't using the function htmlspecialcharacters(input) to guard against hacking of your site. He's a hacker or didn't know.

[@lindhe]

Is this method secure for passwords, or was it just an example?

[@swapnilsonsurkar2136]

[@HorrendouslyExremelyBad]
