  1. HI all, I am building a php application and i am wanting to use notifications. At the moment i am just wanting to understand the methodology behind this. I dont necessarily have a use case for these notifications yet but i am going to base it off of the following: A user submits something to the database, another user gets a notifications that this has happened. I see the notifications being something appearing in the header bar (saying "you have a notification"...)

  4. What is the best table structure when constructing what will be a potentially large multi-user platform? Example- Each user inputs their own individualized information into a table, for recall only to that specific user and to certain other users defined as administrators or half-administrators super users. Would it be better to store this all in a single table, or to give each user their own individual table on formation of the account?

  8. Hi friends, i have a problem. i try to make pagination. I didn't added numbers and the number stayed next to the images. Numbers is no display and it is next the images. And i don't want to give "padding-left" for first image but when i use "padding-left" for images, it is giving all of them. <?php $sayfa = intval($_GET["sayfa"]); if(!$sayfa) {$sayfa = 1;} $say = $db->query("SELECT * FROM resimlerekle"); $toplamveri = $say->rowCount(); // Verileri Saydırdık $limit = 8; $sayfa_sayisi = ceil($toplamveri/$limit); if($sayfa > $sayfa_sayisi) { $sayfa = 1; }

  11. I'm helping a friend in developing a project for our alma mater. And its based on this paper: An Enhanced Indoor Positioning Method Based on Wi-Fi RSS Fingerprinting So far 80% of the web app is finished except for the algorithm (We have no experience with algorithms to source code translations) that needs to be implemented in the website. Inside this paper there is this algorithm that the proponents of the research used. (attached as screenshot). The algorithm was converted to code by using MATLAB, but we are trying to use PHP with our project. Based on the pseudo code the calculati

  13. Hi, I have a form for news articles. It has a title and a body which is fine. I also have a search box that allows the user to search for a memeber and click their name when it appears. This moves a div with a data-id into another div. The purpose of this is to tag them in the article. I am able to post all of the simple stuff but how would i post these value. I am assuming that i would need to create an array of said values but i am struggling to get them showing in post at all. Here is the code i have so far <?php function searchForPeople($searchVal, $exclude = '0'){
  14. Hi all, I find myself in need again on PHP coding and the support last time was outstanding (no creeping here) so I am trying my luck again! I am trying to use a HREF link (lots of individual ones) to search a Mysql database and return the results in a PHP page. Example of HREF links on the page are here: https://flighteducation.co.uk/Create.html and in theory you click a career and it 'gets' and 'shows' the data from the database here: https://flighteducation.co.uk/Careers.php so, you click the 'Animator' link ->it goes to my database and drags back all the da

  24. Hi, simply put; I am having a very difficult time trying to find a way I can Match (partial?) strings, comparing to 2 arrays (the matches have different [Keys].) for example: $abs="Bob Rob Sue"; $abt="sometext Bob1:2 moretext Sue3:4 othertext Rob5:6 etc"; how can I put into code, when "Bob1:2" is used, it finds a match of "Bob", and assigns the complete string of "Bob1:2" ?
