  1. You should have searched these forums for "calendar"...
  2. I'd be tempted to have an age_group table (id, group_name, lo_age, hi_age) and join to that on if_age BEWEEN lo_age AND hi_age. It would save all those case statements and ensure consistency. BTW, your current age ranges exclude 80 year olds.
  3. No need. That happens automatically. It's a case of "set it, forget it"
  4. That still isn't going to work! (unless you aren't using PDO as you stated) mysqli_query() is not a PDO method (the clue's in the name). Get into the habit of using prepared statements and not putting variables in the sql code. $insert = "UPDATE users SET profile_img = ? WHERE username = ?"; $stmt = $connect->prepare($insert); $stmt->execute( [ $filename, $_SESSION['username'] ] );
  5. Sort the array first. Assuming you start with ... $options = [ [ 'type' => 'Visual disability', 'name' => 'Audio-described cut-scenes' ], [ 'type' => 'Visual disability', 'name' => 'Highlighted path to follow' ], [ 'type' => 'Physical disability', 'name' => 'Sensitivity settings for all the controls' ], [ 'type' => 'Visual disability', 'name' => 'Screen readers on menus' ], [ 'type' => 'Visual disability', 'name' => 'Slow down the game speed' ], ]; then ...
  6. If that is "fixed" then your testing is a little lax. Have you checked if the record is actually being updated (by magic, no doubt, as no query is executed)?
  7. You can store images in a database but it's not advised. Best way is store the image file in the file system and store the image location and metadata in the database.
  8. $this->pdo now contains your pdo connection. so $db = new DB; $stmt = $db->pdo->prepare(...) You should extra code to your class to set the connection's charset (UTF-8) and to set PDO::ATTR_EMULATE_PREPARES to false. It's also useful to set the PDO::ATTR_DEFAULT_FETCH_MODE attribute also.
  9. Change to $id = $_GET['id'] ?? DEFAULT_ID;
  10. Probably because the inner loop's result object is overwriting the outer result object as you store them both in $query. But don't run queries inside loops like that . Use a single query with a join to get all the data in a single query. It's far more efficient. SELECT faqc_name , faq_id , faq_question FROM faq_cats c JOIN faqs f ON f.faq_cat = c.faqc_id WHERE faqc_site = :site ORDER BY faqc_id , faq_id
  11. PHP has array_product(). EG echo array_product([1, 2, 3, 8]); // 48 If you want to be able to supply separate arguments to a function instead of an array EG echo mul(1, 2, 3, 2, 4); then you can define the function as function mul(...$a) { return array_product($a); } echo mul(3,8,2); //48 echo mul(1,2,3,2,2,2) //48

  13. All you need is $insert_array = [ 'site_name' => 'asdfasdf', 'site_address' => 'Asdffads', 'description' => 'Asdfs', 'contact_phone' => 'Asdfsdaf' ]; $stmt = $conn->prepare("INSERT INTO Sites (site_name, site_address, description, contact_phone) VALUES (:site_name, :site_address, :description, :contact_phone) "); $stmt->execute($insert_array);
  14. One way would be to rename your input fields to something like name = 'jour[$jour][workday]' name = 'jour[$jour][startTime]' name = 'jour[$jour][endTime]' your posted data will then be nicely grouped Array ( [jour] => Array ( [1] => Array ( [workday] => 01/12/2020 [startTime] => 08:00 [endTime] => 06:00 ) [2] => Array ( [workday] => 02/12/2020 [startTime] => 08:30
  15. You are calculating the rank out of the whole population, not just the class. You need to include the class (armslevelid) in the groupings giving EDIT -- use code tags (<> button)
