3 pointsThe code in each switch is identical so all it achieves is to ensure the calculation uses only the defined list of diameter options. Just use an array of the valid values to verify the values. You can use the same array to generate the option list <?php $diam_vals = [2,3,4,6,8,10,12,14,16,18,20,22,24,26]; $results = ''; if ($_SERVER['REQUEST_METHOD']=='POST') { $x = $_POST['x'] ?? 0; $y = $_POST['y'] ?? 0; $diametre = $_POST['diametre'] ?? 0; if ($x > 0 && $y > 0 && in_array($diametre, $diam_vals)) { $rayon = $diametre * 38.1; $dc = $x/2; $ad = ($y/2)-$rayon; $ac = sqrt(pow($ad,2) + pow($dc,2)); $ec = sqrt(pow($ac,2) - pow($rayon,2)); $LongueurBayonette = $ec*2; $alpha = asin($dc/$ac); $alpha = $alpha*180/M_PI; $beta = acos($rayon/$ac); $beta = $beta*180/M_PI; $angle = 180-$alpha-$beta; $results .= "X = " . $x . "mm" . "<br/>"; $results .= "Y = " . $y . "mm" . "<br/>"; $results .= "Longueur = " . number_format($LongueurBayonette,1) . " mm" . "<br/>"; $results .= "β = " . number_format($angle,1) . "°" . "<br/>"; $results .= "Rayon = " . $rayon . " mm" . "<br/>"; $results .= "φ = " . $diametre . '"' . "<br/>"; } else { $results = 'Inputs are not valid'; } } ?> <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Simplified Example</title> </head> <body> <form method="post" action=""> <fieldset> X: <input type="text" name="x" value="" /> <br/> Y: <input type="text" name="y" value="" /> <br/> Diametre: <select name="diametre"> <option value="0"> </option> <?php foreach ($diam_vals as $d) { echo "<option value='$d'>$d</option>\n" ; } ?> </select> <input type="submit" value = "Calculer" /> </fieldset> </form> <br> <?=$results?> Just curious - do you have a diagram of how those values relate to one another. It metions "rayon" and "bayonnette" so my guess is that it is some kind of laser rifle with attached bayonet (but I could be wrong) 😊

1 pointI have been playing around with a possible database solution to your problem Given that a postcode such as "EH12 3AB" breaks down into four parts viz +------+----------+--------+------+ | area | district | sector | unit | +------+----------+--------+------+ | EH | 12 | 3 | AB | +------+----------+--------+------+ ... I was toying with this table structure CREATE TABLE `postcode` ( `pc_id` int(11) NOT NULL AUTO_INCREMENT, `seller` int(11) DEFAULT NULL, `area` varchar(2) DEFAULT NULL, `district` varchar(2) DEFAULT NULL, `sector_min` char(1) DEFAULT NULL, `sector_max` char(1) DEFAULT NULL, `unit_min` char(2) DEFAULT NULL, `unit_max` char(2) DEFAULT NULL, `deliverable` tinyint(4) DEFAULT NULL, `price` decimal(8,2) DEFAULT NULL, PRIMARY KEY (`pc_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; +-------+--------+------+----------+------------+------------+----------+----------+-------------+-------+ | pc_id | seller | area | district | sector_min | sector_max | unit_min | unit_max | deliverable | price | +-------+--------+------+----------+------------+------------+----------+----------+-------------+-------+ | 1 | 1 | EH | 1 | 1 | 4 | AA | ZZ | 1 | 1.50 | | 2 | 1 | EH | 1 | 5 | 5 | AA | BZ | 1 | 1.80 | | 3 | 1 | EH | 1 | 5 | 5 | CA | ZZ | 0 | 2.00 | | 4 | 1 | EH | 2 | 1 | 9 | AA | ZZ | 1 | 2.25 | | 5 | 1 | EH | 3 | 1 | 9 | AA | PZ | 1 | 2.50 | +-------+--------+------+----------+------------+------------+----------+----------+-------------+-------+ My code was $postcodes = [ 'EH1 2DB', 'eh15bg' , 'eh1 5ba', 'eh15dg', 'EH2 7HJ', 'EH3 2PT', 'EH3 8SX', 'EH146DE' ]; echo '<pre>'; foreach ($postcodes as $pc) { vprintf('%s%s %s%s : %s<br>', deliveryPrice($db, $pc)); } echo '</pre>'; function deliveryPrice($db, $pcode) { $pcode = strtoupper(str_replace(' ', '', $pcode)); $area = $district = ''; $sector = substr($pcode,-3, 1); $unit = substr($pcode, -2); $l = strlen($pcode); $first = str_split(substr($pcode, 0, $l-3)); foreach ($first as $c) { if (ctype_digit($c)) { $district .= $c; } else { $area .= $c; } } $res = $db->prepare("SELECT price FROM postcode WHERE area = ? AND district = ? AND ? between sector_min AND sector_max AND ? BETWEEN unit_min AND unit_max AND deliverable "); $res->execute( [ $area, $district, $sector, $unit ] ); $p = $res->fetchColumn(); $price = $p ? number_format($p, 2) : 'N/A'; return [$area, $district, $sector, $unit, $price ]; } RESULTS: EH1 2DB : 1.50 EH1 5BG : 1.80 EH1 5BA : 1.80 EH1 5DG : N/A EH2 7HJ : 2.25 EH3 2PT : 2.50 EH3 8SX : N/A EH14 6DE : N/A

1 pointthere is something wrong with $query->wheres, it's not countable. So it's not an array or not an object. Do var_dump($query->wheres); after the $query = to find out what it is and what it does contain.

1 pointconsider <?php $dt1 = new DateTime(); $dt2 = new DateTime('2019-12-31'); echo $dt1->diff($dt2)->d . '<br>'; //--> 24 echo $dt1->diff($dt2)->days . '<br>'; //--> 177 ?> "d" gives days as in 6 months 24 days. "days" gives the total number of days

1 pointIt looks like your rule is slightly malformed. As I said earlier, I've found the add_rewrite_rule() function to be a bit fiddly - I try to use the 'rewrite_rules_array' filter instead. Try this: add_filter('add_rewrite_rules' ,'add_kudoskey_rule'); function add_kudoskey_rule(array $rules){ $new = [ 'kudos/([^/]+)/?$' => 'index.php?pagename=kudos&kudokey=$matches[1]', ]; $rules = array_merge($rules, $new); return $rules; } Now, with this in place you should be able to (after you've gone to the Permalinks page and clicked 'Save' to clear the rewrite cache) go to 'http://127.0.0.1/kudos/JFMGTTQ5' and it should show that specific kudos. If you want to get the kudos key referenced in the URL, use get_query_var('kudoskey'). If you want to show an archive listing of all kudos records, make sure that 'has_archive' is set to true in the arguments array of your custom post type registration call, then go to 'http://127.0.0.1/kudos' and you should see the listing. The whole point of adding a rewrite rule is to enable pretty URLs and to not have to use '?variableName=variableValue' because it's easier for the user and better for SEO.

1 pointYes. Here's a simplified version of your application as an example FORM CODE <?php // // FOR DEBUG PURPOSES ONLY - LIST CONTENTS OF SESSION PLAYLIST // session_start(); if (isset($_SESSION['playlist'])) { echo '<pre>', print_r($_SESSION['playlist'], 1), '</pre>'; echo "</hr><br>\n"; } ?> <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <script> $().ready( function() { $(".btn").click( function() { var vid = $(this).data("id"); var vname = $(this).data("name"); $.post( "my_cart.php", { "voice_id" : vid, "voice_name" : vname}, function(resp) { var list = "<tr><td><b>ID</b></td><td><b>Title</b></td></tr>\n"; $.each(resp, function(k, v) { list = list + "<tr><td>" + k + "</td><td>" + v + "</td></tr>\n" }) $("#playlist").html(list) }, "JSON" ) }) }) </script> </head> <body> Song 1 <button type="button" class="btn btn-primary" type="submit" style="padding: 5px 83px 5px 83px;" data-id="1" data-name="song-1.mp3">Add to PlayList </button> <br> Song 2 <button type="button" class="btn btn-primary" type="submit" style="padding: 5px 83px 5px 83px;" data-id="2" data-name="song-2.mp3">Add to PlayList </button> <br> Song 3 <button type="button" class="btn btn-primary" type="submit" style="padding: 5px 83px 5px 83px;" data-id="3" data-name="song-3.mp3">Add to PlayList </button> <br> Song 4 <button type="button" class="btn btn-primary" type="submit" style="padding: 5px 83px 5px 83px;" data-id="4" data-name="song-4.mp3">Add to PlayList </button> <br> Song 5 <button type="button" class="btn btn-primary" type="submit" style="padding: 5px 83px 5px 83px;" data-id="5" data-name="song-5.mp3">Add to PlayList </button> <br> Song 6 <button type="button" class="btn btn-primary" type="submit" style="padding: 5px 83px 5px 83px;" data-id="6" data-name="song-6.mp3">Add to PlayList </button> <br> <br> <h2>Playlist</h2> <table style="width:600px" id="playlist"> </table> </body> </html> MY_CART.PHP <?php session_start(); if ($_SERVER['REQUEST_METHOD']=='POST') { $voice_id = $_POST['voice_id'] ?? 0; $voice_name = $_POST['voice_name'] ?? ''; if ($voice_id && $voice_name) { $_SESSION['playlist'][$voice_id] = $voice_name; exit(json_encode($_SESSION['playlist'])) ; } } exit("ERROR") ; ?>

1 pointJust my 0.02 worth ... 1. It is always a bad idea to place values provided by the user ($_GET, $_POST, $_COOKIE) directly into your SQL. A better way is this, which avoids doing that and also checks that only valid column names can be used $sort = $_GET['sort'] ?? ''; switch ($sort) { case 'recd_date': $orderby = 'location, recd_date, name'; break; case 'sent_date': $orderby = 'location, sent_date, name'; break; case 'birth_date': $orderby = 'location, birth_date, name'; break; default: $orderby = 'location, name'; break; } 2. Use prepared statements to place values into your query $result = $db->prepare("SELECT * FROM $company WHERE member = ? ORDER BY $orderby "); $result->bind_param('i', $member_number[$i]); $result->execute(); 3. The use of that [$i] index - are you running the query in a loop for different member_numbers? Don't. 4. You have a variable table name ($company) which suggests you have several tables, each for a different company. Better to have a single table and add an indexed "company" column.

1 pointWhat versions of the various react/* packages are you using exactly? Run composer info to find out. Based on the backtrace it seems you are probably using react/event-loop v0.4.3, and I'm guessing the other packages you have are from around the same time frame. I downgraded my install to react/socket v0.7.2 and whatever secondary packages match that release and was able to encounter some instances where a client would connect then immediately disconnect causing various errors to be returned by s_client. I suspect you're hitting this issue: Only close stream when the we reached end of the stream. Try updating your react requirements to their latest versions and see if that resolves your issues.
