I want to recognize (with php, mysql) and save which blog entries a user has clicked. Like, I have tech entries, lifestyle entries etc. and I want to record which entries a user is interested in, so that I could provide just these entries for him!
So you know what I mean? I wonder if there are any tutorials or something.
Thanks, dartox.
When they are opening the page, just store the id of that blog entry in a table. Down the road, you can do something as simple as COUNT (*) on that table for that user, sort by category, and find out what category they're mostly interested in. You can get really complex for recommendations, but this is one of the more simpler ways of accomplishing it. Hope that helps!
I like to use www.statcounter.com
So create a page: tracker.PHP, and in it put the tracking code from statcounter (or Google analytics for that matter)
On every page with links I'd put a hidden iframe with an id="tracker" and no src just yet, :
<iframe id="tracker" style="visibility:hidden;height:0px;width:0px;" frameborder="0">
</iframe>
Then every link I'd do something like:
<a href="/some_tech_article.php"
onclick="document.getElementById('tracker').src='/tracker.php?location=techarticle';">Tech Articles
</a>
So everytime someone clicks a link, the iframe will invisibly load your tracker.php page and send any information you want to send in the URL (as a $_GET php variable)....from there you can track and save whatever information you'd like into a database or whatever.
You can use this trick to send information behind the scenes when users click things, without switching pages. I use this to track clicks, and update tables in mysql.
If you need me to give you a better example let me know!

The title may be a little vague, but I'll try to explain the concept here.
I have a site in which daily new items ( sports games ), get published, now what I would love is that my users would be able to click on a certain game and get redirected to a new page with more detailed information about that one game.
The thing is, creating every php page seperate for every game each day is a lot of work because also a lot details in the page need to be changed.
Now I was wondering if it is possible in some kind of way that there's a script that reads, OK you have 5 games today, page 1 = id number, title of the page is the matches name, extra info is the info that stands with that id.
I don't know how else to explain this so I hope this was good enough.
Thanks for your time and reading this :)
You can use requests to select the page (the best way is to use $_GET as suggested by gbestard) to select the ID. Then you can have some static content (like url or short article or link to screen shot or something similar) stored in your database under the same ID as the game, and upon clicking on the link to the game, the page is reloaded and you populate it with the new content, that was stored in the database.
You can even store entire pages with static html (as in article or short game description in your case) content and etc in your database and simply call them to populate a div.
If you have something like a custom made admin section of your site, you can add a page to edits it with a js plugin like ckeditor and the creation/editing of articles will be a piece of cake.
It's pretty much a standard case of a CMS(Content management system).
I have a couple of pages where the user can add and remove stuff in order to update the results. i.e. in a "ShoppingList"-page where the user can add/remove drinks in order to see what ingredients they need.
Each of these drinks is stored in a cookie, with PHP, so the user have the ability to navigate and explore the site, and then return without having to add the drinks again...
When the user do this, adds/removes drinks, the entire page is reloaded.
Drinks are added to a cookie immediately, before any html and stuff, then refreshed once again in order to build the php.mysql.query based on the values now stored in the cookie.
I think this is a lot of unnecesary reloading and stuff. It should be something more like just refreshing the actual content that needs to change, and not reloading everything else - Lots of unnecesary mysql requests just to add/remove a drink from the shoppinglist. And this of course slows site down..
Whenever the page is loaded, I need to check the cookie in order to present the correct results. Then, when a user adds/removes a drink, I would like to do this in the background (update the cookie and update the result). Hopefylly this could speed up the user experience.
I have a site up'n'running here - as a "prototype" : http://barkeeper.thomaskile.me/?side=handleliste (norwegian site, but google translate sort of gives you an idea of what it says. just tested it..)
This same thing goes for all three pages on my site so far..
Any suggestion on how to accomplish this? Is it som sort of jquery.AJAX-thing? If so. WHere do I start any sort of ajax-thing. Not sure how that works in practice when the user doesn't do anything (on page load)...
This is usually done by manipulating DOM.
Remove the element from one list and create it in another list.
Checkout jQuery - the javascript library.
I'm currently only using PHP to take user submissions, put them in a database, and echo them out on a page using SQL to select from a table, such as comments. I need a system that will automatically update comments without refreshing the page like on YouTube. The less the user has to manually update, the better.
I want it to work pretty much exactly how YouTube and Twitter function, where it'll say "x NEW COMMENT(s)" and clicking that updates everything.
My teacher recommended a JQuery function, but I don't have any background in that language so I don't know where to begin looking.
I'm at a complete impasse. I will update this if you guys need additional information to aid in my search.
You are looking for AJAX
You will need a HTML page with jQuery/AJAX that calls another PHP page. In that PHP page you do the DB request and then ideally return the data as JSON so that your frontend part can display it to the user.
As every one says, AJAX is the way. You can find a simple blog I did on it here.
I have completely no idea where to start so I apologise about the lack of code presented to you.
My problem is - I have a page of information, ordered by ID (gathered from the database). These ID's are referenced from another page to which the user clicks on a link and it takes them to the page with the information on, how ever, there could be potentially hundreds of ID's on that page - So I need to reference each specific ID so when the user clicks, it will take them to the exact position of the ID.
I understand its something like localhost:8888/index.html#id3 etc..
But i'm struggling to understand how to reference for a PHP Variable.
Many thanks in advance.
You would use anchors, so for example, on the page where you list your information, attach an anchor to it such as #id1, then on your links page, you would place the #id1 at the end of the url results.html?#id3
The short version of what I am looking to do is make a "safe" and idiot-proof page, at least as much as possible.
I have researching the best way to make every hyperlink on a page (ie. standard menus used on the page or any other hyperlinks outside of a HTML form) submit/POST the form information and then redirect to the page clicked on.
For some reason not all users remember the "Save" button before clicking on something else. Then they are upset because they didn't save their information. I would much rather have all the information be saved before sending them on to the hyperlink's URL.
Helpful information:
- This is on a PHP based project.
- I have already put in place code to "detect" what kind of page is in use and if the feature is needed.
- I have header() redirects in some places for other items, so that is nothing new.
- I have looked at javascripts to add, when needed, so that the form is POSTed, and found some options for that.
At this point I can't get the final steps put together, such as a javascript that would POST the information AND store the URL that the hyperlink was supposed to go to. Process the POST information and then redirect to the stored URL.
Dream Example:
onclick="submitformandforward("Example_form", "http://example.mysite.com/example_page.php?querystring=Y")"
Any suggestions, tips, examples, etc are warmly welcomed!
Thanks.

Javascript is the tool you require...
remember some people may have it switched off...
Wehn some clicks a link - check that the form values have been altered - if not carry on - if they have inform that that changes need saving...
