A CORRECTION TO THIS VIDEO! In the part where I create the exit() function, you need to make sure you place it AFTER the header() function! Otherwise the script is obviously exited before it even runs the header() function. 😂 Me dum dum me see rock smash smash hehe 😂

Great videos! I am enjoying your format of training. I haven't programmed in 20 years and surprised to see PHP is still popular. Back then we had PHP and ASP (active server pages). Although I left programming before getting too deep into all that. My boss sent me to ASP training but we never really got very far with web development where I was working although they wanted to.

Hi. The user can change the required option in the frontend via inspect based on your permission in the file manager. Using Chmod 644 for files and 755 for folders will not allow the users change the required option via inspect. Awesome tutorial by the way.

@Ithicuss Ай бұрын

Very nice series so far. Enjoying it a lot. Perhaps a stylistic preference I would like to point out is that at the end of the if statement you have the header function, then an else block and another header pointing to the same address. It might be easier not to have an else statement and just move the header function below the if statement. If the user makes a post request the header function is evaluated after the if statement and if the user does not make a post request the if statement is skipped and the header function is executed. What do you think?

@Dani_Krossing Ай бұрын

The headers are for sending the user back, with a specific message in the URL. 🙂 Either a success message, or a specific error message. So they would need to be at the end of each statement. But you are right, because I didn’t actually add the error messages inside the various headers, so as they were left at the end of the video, they are duplicates. So a final last step is to add the error messages. 🙂👍

@_ChildofYeshua_ 7 ай бұрын

Send to same form = Action = "name of that same form" So if your form is on the index.php form then just call that form action="index.php" without including the super global. If you're gona use the super global then make sure to sanitize it i.e strip_tags, stripshlashes, trim, html entities etc...

You can use htmlspecialchars() for that too yes, however we do also have more specific sanitization functions you can use for non-string data. Such as filter_var or filter_input.

could you/should you use "required" on the client-side as well as the server-side validating of the empty field? or is that unnecessary?

@Dani_Krossing 19 күн бұрын

“required” is just there to give a visual indicator. 🙂 You’ll even notice that even though it is supposed to prevent the form from being submitted, if you spam the submit button fast enough, it will still occasionally submit the form… So security wise, “required” is pointless in itself. So if you feel that you wanna add it in, go ahead. 🙂 It is an easy and fast way to notify a user, if they forgot to fill in an input. Just know that it is ONLY a visual indicator.

@ShootYourBricks Жыл бұрын

If I have a page with php and html, is it still good to omit the end ?> tag as long as there's no html at the end?

@Dani_Krossing Жыл бұрын

Omitting the closing tag should only be done in "code only files". So if you have a document that acts as a "page" inside your website, then you should include the closing tag.

Good afternoon, Dani. Thanks for all your tutorials. Question: I feel that I have to choose between Javascript and PHP. For front-end coding and eventually also for back-end coding. What do you say, Javascript or PHP? Greetings, Ruud (Amsterdam, Holland)

@Dani_Krossing 5 ай бұрын

Hi. I'm a bit confused by the question. You say you need to learn a front-end and a back-end language? Then it makes sense to learn both, seeing JavaScript is front-end, and PHP is back-end. 🙂 JavaScript CAN be learned as a back-end language as well, if done so through frameworks like Node.js... But PHP is still vastly more popular as a backend choice.

This code snippet you gave: if(empty($_POST['name'])) { exit(); header("Location: ../index.php"); } I think the header line will be unreachablbe or I am missing something. The exit() function is exiting what, the if statement or the page?

@Dani_Krossing Жыл бұрын

Yes very good point, I included that in a pinned comment right after I uploaded this video. 🙂 Otherwise a few things can go wrong, one for example being that the form gets resubmitted on refresh. Exit() is also a valid function to use. Most people use Die() when you need to stop the script because of an error, and Exit() whenever everything went as expected. The main difference between the two is that one closes the HTTP connection, and the other one doesn’t.

HTML is a part of PHP. You should know HTML before getting into PHP, since many PHP features require HTML to work. So if you don't know HTML, I wouldn't recommend jumping ahead to PHP. I will be talking a lot more about HTML in these videos ahead, since it is necessary.
