    Put this line just before the mysqli connection code... mysqli_report(MYSQLI_REPORT_ERROR|MYSQLI_REPORT_STRICT); Ensure error_reporting is ON. You should now get error messages if there are problems with a query.

    PS You aren't doing yourself any favours by insisting on mysqli. PDO is a superior library and easier to use. While you are still learning, put your effort into PDO
  3. Barand
    Change $pdo = pdoConnect(); to $pdo = new mysqli(HOST, USERNAME, PASSWORD, DATABASE); Job done.

    BTW, it seems a pity that that those students who attain a C6 grade should receive only an anagram instead of a Credit

    @sule, Here are two version of the program A single loop tracking changes in studentid (as I suggested) Stores data in a muti-dimensional array and uses nested foreach() loops Version 1 <?php define("HOST", 'localhost');

    I've just described a method to you. What have you now tried? (or are you just going to keep repeating the same question without trying the suggestion?)
  8. Barand
    As you loop throught the query results, check for a change of studentid. Each time to reach a new student, out put the report headings (name, photo etc) then continue listing subject rows until the next change. Pseudocode... previd = 0; foreach result row { if studentid != previd { previd = studentid output report headings } output subject data }
  9. Barand
    I couldn't find anything wrong with your query, although I had to limit my version to the marks table only as the other tables required seem to have fallen down the back of your sofa. I assumed you want the positions in their class. SELECT -- marks.acayear -- , marks.semester -- , marks.form -- , marks.class marks.studentid , marks.name , marks.subject , marks.class_score1 , marks.exam_score1 , marks.total , marks.remarks , RANK() OVER (PARTITION BY marks.lessonsid, marks.acayear, marks.form, marks.semester, marks.subject, marks.class ORDER BY marks.total DESC) as rank FROM marks WHERE marks.acayear='2024/2025' AND marks.semester='1' AND marks.form='3' AND marks.class='SCI A' ORDER BY name, SUBJECT; +-------------+--------------------------+----------------+--------------+-------------+-------+-----------+------+ | studentid | name | subject | class_score1 | exam_score1 | total | remarks | rank | +-------------+--------------------------+----------------+--------------+-------------+-------+-----------+------+ | 82611900422 | ABDUL-HANAN SA-EED | BIOLOGY | 0 | 0 | 0 | | 23 | | 82611900422 | ABDUL-HANAN SA-EED | CHEMISTRY | 0 | 0 | 0 | | 29 | | 82611900422 | ABDUL-HANAN SA-EED | ELECTIVE MATHS | 0 | 0 | 0 | | 29 | | 82611900422 | ABDUL-HANAN SA-EED | ENGLISH LANG | 0 | 0 | 0 | | 29 | | 82611900422 | ABDUL-HANAN SA-EED | ICT | 0 | 0 | 0 | | 26 | | 82611900422 | ABDUL-HANAN SA-EED | INT SCIENCE | 0 | 0 | 0 | | 29 | | 82611900422 | ABDUL-HANAN SA-EED | MATHEMATICS | 0 | 0 | 0 | | 25 | | 82611900422 | ABDUL-HANAN SA-EED | PHYSICS | 0 | 0 | 0 | | 27 | | 82611900422 | ABDUL-HANAN SA-EED | SOCIAL STUDIES | 0 | 0 | 0 | | 26 | +-------------+--------------------------+----------------+--------------+-------------+-------+-----------+------+ | 80106802422 | ABDUL-RAHMAN NASIBA | BIOLOGY | 23.4 | 53.9 | 77.3 | Very Good | 3 | | 80106802422 | ABDUL-RAHMAN NASIBA | CHEMISTRY | 16.8 | 53.2 | 70 | Very Good | 6 | | 80106802422 | ABDUL-RAHMAN NASIBA | ELECTIVE MATHS | 16.8 | 53.9 | 70.7 | Very Good | 11 | | 80106802422 | ABDUL-RAHMAN NASIBA | ENGLISH LANG | 20.1 | 39.2 | 59.3 | Credit | 18 | | 80106802422 | ABDUL-RAHMAN NASIBA | ICT | 16.8 | 23.8 | 40.6 | Pass | 25 | | 80106802422 | ABDUL-RAHMAN NASIBA | INT SCIENCE | 20.1 | 39.2 | 59.3 | Credit | 14 | | 80106802422 | ABDUL-RAHMAN NASIBA | MATHEMATICS | 16.8 | 30.8 | 47.6 | Pass | 21 | | 80106802422 | ABDUL-RAHMAN NASIBA | PHYSICS | 16.8 | 53.9 | 70.7 | Very Good | 8 | | 80106802422 | ABDUL-RAHMAN NASIBA | SOCIAL STUDIES | 13.5 | 23.1 | 36.6 | Fail | 25 | +-------------+--------------------------+----------------+--------------+-------------+-------+-----------+------+ | 82606700822 | ABUBAKARI ABDUL HALIK | BIOLOGY | 13.5 | 45.5 | 59 | Credit | 11 | | 82606700822 | ABUBAKARI ABDUL HALIK | CHEMISTRY | 22.8 | 53.9 | 76.7 | Very Good | 5 | | 82606700822 | ABUBAKARI ABDUL HALIK | ELECTIVE MATHS | 13.5 | 39.2 | 52.7 | Crdeit | 26 | | 82606700822 | ABUBAKARI ABDUL HALIK | ENGLISH LANG | 20.1 | 46.2 | 66.3 | Good | 14 | | 82606700822 | ABUBAKARI ABDUL HALIK | ICT | 13.5 | 46.2 | 59.7 | Credit | 15 | | 82606700822 | ABUBAKARI ABDUL HALIK | INT SCIENCE | 22.8 | 53.9 | 76.7 | Very Good | 5 | | 82606700822 | ABUBAKARI ABDUL HALIK | MATHEMATICS | 23.1 | 45.5 | 68.6 | Good | 10 | | 82606700822 | ABUBAKARI ABDUL HALIK | PHYSICS | 13.5 | 23.8 | 37.3 | Fail | 24 | | 82606700822 | ABUBAKARI ABDUL HALIK | SOCIAL STUDIES | 16.8 | 30.8 | 47.6 | Pass | 21 | +-------------+--------------------------+----------------+--------------+-------------+-------+-----------+------+ | 80115900922 | ALAWI ABDALLAH | BIOLOGY | 10.2 | 37.8 | 48 | Pass | 13 | | 80115900922 | ALAWI ABDALLAH | CHEMISTRY | 22.8 | 38.5 | 61.3 | Credit | 8 | | 80115900922 | ALAWI ABDALLAH | ELECTIVE MATHS | 23.1 | 39.2 | 62.3 | Credit | 20 | | 80115900922 | ALAWI ABDALLAH | ENGLISH LANG | 16.8 | 53.9 | 70.7 | Very Good | 12 | | 80115900922 | ALAWI ABDALLAH | ICT | 13.5 | 39.2 | 52.7 | Crdeit | 22 | | 80115900922 | ALAWI ABDALLAH | INT SCIENCE | 19.8 | 37.8 | 57.6 | Credit | 16 | | 80115900922 | ALAWI ABDALLAH | MATHEMATICS | 26.4 | 46.9 | 73.3 | Very Good | 3 | | 80115900922 | ALAWI ABDALLAH | PHYSICS | 16.8 | 38.5 | 55.3 | Credit | 17 | | 80115900922 | ALAWI ABDALLAH | SOCIAL STUDIES | 13.5 | 23.8 | 37.3 | Fail | 24 | +-------------+--------------------------+----------------+--------------+-------------+-------+-----------+------+ | etc...

    You can't concatenate an if() statement like that. Try $message = 'Message goes here' . "\r\n" . 'Name: ' . $name . "\r\n"; if ($doesthishavedata != '') { $message .= 'Does this have data: ' . $doesthishavedata . "\r\n"; } $message .= 'something else: ' . $hasdata . "\r\n" .
  11. Barand
    An "if() construct" often comes in useful at times like this.
  12. Barand
    Inser queries cannot have a WHERE clause. You need an UPDATE query
  13. Barand
    You don't need the braces so long as there are only single statements to be executed but only if they are in the same <?php .. ?> block of code. EG this works... <?php if (date('d')==24) echo 'today'; else echo 'Not today'; ?>
  14. Barand
    Are you using <?php ... ?> or <? ... ?> in your code when you enter a php code section? The short version (<?) is no longer a default and requires an ini file setting to enable.
  15. Barand
    I'd do something like this... <?php $data = [ '46.105.73.18:27015' => [ 'gq_address' => '46.105.73.18', 'gq_dedicated' => '', 'gq_gametype' => '', 'gq_hostname' => '', 'gq_joinlink' => 'steam://connect/46.105.73.18:27015/' , 'gq_mapname' => '', 'gq_maxplayers' => '', 'gq_mod' => '', 'gq_name' => 'Counter-Strike: Source' , 'gq_numplayers' => '', 'gq_online' => '', 'gq_password' => '', 'gq_port_client' => 27015 , 'gq_port_query' => 27015 , 'gq_protocol' => 'source' , 'gq_transport' => 'udp' , 'gq_type' => 'css' , 'players' => Array (), 'teams' => Array () ] ] ; $tdata = ''; foreach ($data as $k => $v) { $v = array_filter($v); // get rid of blank values $tdata .= "<table border='1'> <tr><th>Array key</th><th>" . join('</th><th>', array_keys($v)) .
