I am trying to create a forum on my page. I need some advice. I have MySQL database and I am able to to work with it. Yet as far as I can make is playing with POST. I mean on click submit a $_POST['submit']) becomes set and so on. Then connect to database, get info and display.This way of making a forum is bad, because it all happens on a single page. As far as I seen any other forum when entering one and so on has it's unique Uri (what comes after domain.com/) so you can simply send someone full url and they are in that thread (unlike if you play with $_POST['submit']).
Sorry if my question is not accurate and I am not asking to write me code. I just need someone to direct me to the right place and any advice would be helpful. Thanks !
Your question is difficult to understand, but I think you are confused about how data and pages are dynamic using GET/POST.
The URLS with different IDs are like an illusion. Really, its the same page, however the page is dynamically taking that ID from the URL, and using it to output certain data.
For example, say we habe the URL: www.example.com/show_thread.php?thread=3
The php would look like
if(isset($_GET['thread'])){
$data = $db>query("SELECT thread_title,thread_text FROM threads WHERE thread_id = $_GET['thread']");
print($data);
}
*Warning: do not use this exact code, it is an example, not secure, etc
Then the database would look like
thread_id thread_title thread_text
1 kngwihywoihwy kngwihywoihwykngwihywoihwy
2 vyfngoieyoiehyon ieonuwrtoi hunwrmt jirwyji
3 nuoaiefguneoihn eoithneiotheo
and the page would show
nuoaiefguneoihn eoithneiotheo
POSTing data is for sending it to the server, and doing something with it. Just like GET. However, GET is helpful for passing things around as they are accessible in links. Like this example.

I've got a table with 10 apps in it, I want a page for each of those apps which will look the same but have different information on it. I'm new to PHP so don't really know what to search for.. are there any good resources out there that could help me?
I want the url structure to be like:
/apps/title1
/apps/title2
etc.
The simplest way to do this is query something based on the GET data. You can then use .htaccess or $_SEREVR['REQUEST_URI'] to fetch the link.
So if they went to site.com/?app=Stack you could use this.
echo $_GET['app'];
Which would output Stack.
This is kinda confusing, so forgive me if you don't understand what I am asking. I'm trying to develop my skills and I wanted to move onto images as a next step. I did a bit of searching and I thought a good way to try this would maybe be to generate military ribbon racks depending on the options the user selects.
(See something like this as an example: http://www.ribbon-rack-builder.com/ribbons/build/4)
Now, from looking at the source code I can see that the creator of that website creates a form with all of the different ribbons and allows the user to select the ones they want with checkboxes. This form is then posted to some PHP on the page somewhere.
Being new to the image concept I have no idea what kind of PHP this would be. Could anyone give me an idea of how this website could do this and where I should start should I want to create something similar?
Thanks very much!
First, you'll need to get which checkboxes were checked:
Set the name in the form to check_list[] and you will be able to
access all the checkboxes as an array($_POST['check_list'][])
Second, you'll most likely want to use the GD and Image Functions built into PHP.
There is a lot there, and it can be confusing, so I suggest you do some reading through questions on SO on the subject: https://stackoverflow.com/search?q=merge+image+[php]
Okay. So I don't have any example code to show, but after doing a bit of research and learning the basics of PHP, I think the answer to my question should be pretty simple.
Here is the scenario, as I would like it to be:
On the homepage there will be several team names, with scores next to them. Like "house-points" in Harry Potter.
Below the score is a small text-field. Below that is a submit button.
The user will put a number in the text-field, press submit, and that number will be added to the team's total score.
NOW. I know how to achieve all of that with JavaScript. Easy. What I want to know IS:
How do I make that new number (the new score total) STAY there. I need to permanently alter the HTML when that submit button is pressed.
All I know is that I need to use PHP. I know the basics of PHP, so whatever the answer is, just throw it at me and I'll figure it out.
Sounds like what you want to do is submitting forms. First drop the JavaScript, you won't need it. What you need is to put your text fields in a form and when you submit you can fetch your values with $_<GET|POST|REQUEST>['<name_of_field>'].
Then you will need to store it somehow. The best way to do it is to use a database like MySQL or MongoDB to store it, but it could be a bit tricky if you are just learning this, so maybe you would like to stick to files. You could do this with INI files and PHP's INI functions.
Lastly you will need to print out the correct values to the website. Now this is easy: Just edit your HTML file to do something like
<?php echo $score['team1']; ?>
for each team after retrieving the correct values at the top or something. (Don't forget to rename the HTML file to .php as well).
Now you should be all set to save your scores. =)
If you mean really permanent you'll have to send it to a database via Ajax (combination of PHP and Javascript). OR write it to a text-document, which is less good.
I need to create a 10 page quiz for a mobile browser. It is only a mobile webpage, so no considerations need to be taken for other browsers.
Here's the problem I'm having: I can't use JavaScript, because not every mobile browser supports it. I'm not very skilled in other languages, but I thought perhaps something could be done in PHP as it is server-side.
If my first URL is domain and I enter the correct quiz answer, the URL to the next page could be domain/?p=1. The URL doesn't need to do anything but hold a count of the number of correct results.
As for the actual code, I was thinking it could be included in the HTML itself, as I'm not very concerned about people viewing the source on their mobile phones.
Is it possible to write a line of code that increments the 'p=' attribute in the URL by one when clicked and only attach it to the correct answers?
Here's an image of what I mean: http://i.imgur.com/HbJ5U.jpg
And, what's to stop me from manually incrementing the "correct answer" counter in my address bar?
Do you not want to use a database because you don't have one available to you in your hosting, or because you don't know how?
I'm not a fan of the idea, but you can get the number of "correct answers" with the following code.
<?php
/* Gets current correct answer Count */
$answer_count = $_GET["p"];
/* checks to see if the submitted answer is the same as the correct answer */
if ($_POST["submitted-answer"] == "correct-answer") {
$answer_count++;
}
?>
Now, you just add the modified answer count to the link to the next question.

If this is "just for fun" I don't see why you couldn't do it like this. It's definitely a simple way to solve the problem.
The standard way to do this is to store things in hidden form variables. Of course, if there is anything riding on this, that's a terrible way to do it, because it's really easy for the end user to put his own values in those hidden form values.
Aren't file-based sessions the obvious answer here?
I'm trying to think of a way to create a list of items that I can display on a webpage that my visitors can tick off, without ever having to log in.
The list may be like so:
[ ] Buy potatoes
[ ] Pickup kids
[x] Drink more water
[ ] Go for a Run
If User A visits the site, and clicks "Drink More Water" I want that to save in a database so that when User B visits, "Drink More Water" is already ticked.
Is there any simple ways to do that:
in PHP?
with Javascript?
or even as a WordPress plugin?
Do you know if there's any existing code around that does this?
TaDa List by 37Signals comes very close, but only allows specific people to tick things off.
Any suggestions would be greatly appreciated.
Thanks

If you want to create this yourself you should learn PHP and MySQL (and possibly Javascript (for AJAX)), and HTML and CSS (maybe you already know some of these). After you know these it will become clear how to create this.
You should first learn HTML
then PHP
then MySQL (or any SQL that works with PHP)
then CSS
Then Javascript
We can't really answer your question like this, because it involves big amounts of code. Adn won't really help you if you don't know these languages.
I'll tell you what you need to do, but you're going to have to research most of the things.
You need html to create the list.
You need php to query sql and check if one of them should be checked or not.
Load the page with the data you got from your database server (set the checked ones as checked).
When the user checks one of them you need to store it in the database, so that when another user loads the page he can then get the changes from the database.
Hope this is clear enough.
Just store that information in cookies.
$_COOKIE['ticket'] = 3;
when he visit the page next time just check if $_COOKIE['ticket'] is not empty.
You could do this kind of thing with a file instead of a database. So when the user checks off a box, it loads a PHP file that reads an XML file with the tasks and check-status, then re-writes that file with the modified value.
It's quick, dirty, and doesn't need a database.
You could use a REST like url that defines a list. i.e.: http://ticklist.com/list/145
People can share this common list.
Something like the logic of http://friendpaste.comTo let people share and edit source codes.
