Code is php <?php include 'db.php'; if( isset($_POST['oak']) ){ $alltree = $_POST['alltree']; $oak= $_POST['oak']; $sql = "UPDATE users SET $puud = $puud + 1, $sirel=$sirel+1"; } if (mysqli_query($sql)) { echo "'+1 Oak tree added!"; } ?> <form action="demo.php" method="post"> <input type="submit" name="oak" value="Cut a tree!"> </form> My vision is.. if press CUT A TREE! and page updated.. and update my oak amount at mysql data.. So, i'm newbie but i take a little journey for study :)

Hi guys, I'm starting to get back into coding for a hobby and wondering is there a better way of doing these php and mysql calls? they all work but not sure if it was the efficent way or is there others that everyone else uses? //connection for user details lookup $sql0 = "SELECT uid, fullname, emailaddress, created_at FROM MK_users WHERE uid={$_SESSION['id']}"; $result0 = $conn->query($sql0); //connection for user against role acceess $sql2 = "SELECT role_uid, role_bid, role_access, access_created_at FROM MK_role_access WHERE role_uid={$_SESSION['id']}"; $result2 = $conn->query($sql2); while($row2 = $result2->fetch_assoc()) { $_SESSION['role_bid'] = $row2["role_bid"]; } //connection for role access against business lookup $sql3 = "SELECT businessname, account_type, website, main_address, logo FROM MK_baccounts WHERE bid={$_SESSION['role_bid']}"; $result3 = $conn->query($sql3); while($row3 = $result3->fetch_assoc()) { $_SESSION['businessname'] = $row3["businessname"]; }

Hi there, So the below code is working for 1 entry, however there is 2 entries in the database which are different postcodes and I cannot get to show in Google Maps. When I do it without Mysql and just do it direct it works, but really want to do it from MYSQL - both postcodes are valid and tested as well. <?php $sql4 = "SELECT * FROM MK_migration_details"; $result4 = $conn->query($sql4); ?> function initialize() { geocoder = new google.maps.Geocoder(); var latlng = new google.maps.LatLng(40.768505,-111.853244); var myOptions = { mapTypeControl: false, fullscreenControlOptions: false, zoom: 8, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP } map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); <?php while($row4 = $result4->fetch_assoc()) { $mig_postcode = $row4["postcode"]; } echo 'addPostCode("'.$mig_postcode.'")'; ?> } I know the issue lies with the PHP / Mysql Loop and the Javascript element 'addpostcode' when I put into the loop does not work, but works for a single address outside the loop. Really appreciate your help guys! Thanks you

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 data to the Careers.php page So far this is what I have managed to not get right: HTML (screen shot added/attached Links.png) <a href="Careers Results.php?jobTitle=Animator"> PHP $id = $_GET['jobTitle']; if( (int)$id == $id && (int)$id > 0 ) { $link = mysqli_connect('localhost','MYUSERNAME','MYPASSWORD','MYDATABASE'); // Connect to Database if (!$link) { die('Could not connect: ' . mysqli_connect_error()); } $sql='SELECT * FROM careers WHERE jobTitle=' .$id; $result = mysqli_query($link,$sql); $row = mysqli_fetch_array($result); echo $row['jobTitle']; echo $row['jobDescription']; } else { echo "Record NOT FOUND"; } Up to now the code returns "Record NOT FOUND" so it is passing through the php to the end. I am new to PHP and trying to get my head around it all, and in theory this is the kind php code that I should be looking at, but I am still very new to it!! Any help or advice very much appreciated again!!! Thanks

I have become able to display due data in due column but the same value is showing for each customer - what is the wrong I am doing?

I’m trying to create a trigger that does two things, first take an ip that’s in dot notation and run inet_aton on it and put the result in another field. Second, checks a lookup table to identify an ip range that the result of the first action falls into and enters the id of that row in the table. This is on a mysql database on my web host. Here’s what I’ve tried: DELIMITER // CREATE TRIGGER before_ins_download BEFORE INSERT ON download FOR EACH ROW begin set new.ip_address = inet_aton(new.`ADDRESS`), new.refer=(select `id` from `ip_lookup` as i where new.ip_address between i.start and i.end limit 1 ); END; // DELIMITER ; It works without the new.refer part but after I added that it just seems to hang and never gets to the closing DELIMITER; . All ip columns are indexed. Does anyone see a mistake in my code? Thanks for looking.

When I run either the inet_aton or inet6_aton command on my local mysql server (Server version: 5.7.30-0ubuntu0.18.04.1 (Ubuntu)) I get the following error: mysql> UPDATE download SET ip_address = inet6_aton(ADDRESS); ERROR 1411 (HY000): Incorrect string value: '`test`.`download`.`ADDRESS`' for function inet6_aton When I run the same command on my web host there's no problem. Both have exactly the same table structure and data. The data on the local server was imported from an export of the data on my web host. In both cases, the ADDRESS field is a varbinary(32). I've tried changing the local server to varbinary(16) and re-importing the data but got the same results. I've also restarted the mysql service but it made no difference. Can someone please explain what is going on?

I'm new to using triggers and really not sure how to proceed. I have an access table that a row is inserted whenever someone opens the website or downloads a file with the following structure: `ID` int(5) NOT NULL autoincrement, `LOG_TIME` datetime NOT NULL DEFAULT current_timestamp(), `IP_ADDRESS` int(64) unsigned COLLATE utf8_general_mysql500_ci NOT NULL, `FILENAME` varchar(50) COLLATE utf8_general_mysql500_ci DEFAULT NULL, `country` varchar(50) COLLATE utf8_general_mysql500_ci DEFAULT NULL, `area` varchar(50) COLLATE utf8_general_mysql500_ci DEFAULT NULL, `city` varchar(50) COLLATE utf8_general_mysql500_ci DEFAULT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_general_mysql500_ci; When the site is accessed, a row is inserted with only the first 3 fields are filled. When a file is downloaded another row is inserted with the first 4 fields filled. I want to create a trigger such that when a download row is inserted, the IP_ADDRESS is compared to another table to update the country, area, and city fields. I can currently do that for the whole table in mysql shell using the following code: UPDATE access t2, ip_lookup t1 SET t2.country = t1.country, t2.area = t1.area, t2.city = t1.city WHERE ((t2.IP_ADDRESS) BETWEEN (t1.start_ip) AND (t1.end_ip)) AND t2.FILENAME is not null and t2.country is null; How would I write an "after insert" trigger to update the last 3 fields based on the ip of the row that was inserted because of a download? Thanks in advance, Larry

The following code is showing my result horizontally and I want to show them vertically $id = $_GET['id']; $sql = "SELECT * FROM users WHERE id = $id"; $result = $conn->query($sql); if ($result->num_rows > 0) { echo "<table align=\"center\">; <tr> <th>ID</th> <th>First Name</th> <th>Last Name</th> <th>Email</th> <th>Join Date</th> </tr>"; // output data of each row while($row = $result->fetch_assoc()) { echo "<tr> <td>".$row["id"]."</td> <td>".$row["fname"]."</td> <td>".$row["lname"]."</td> <td>".$row["email"]."</td> <td>".$row["reg_date"]."</td> </tr>"; } echo "</table>"; } Any idea? Thanks in advance

I am trying to add a bootstrap class to php echo in mysql query but it doesn't work Here the code that I using $result = $conn->query($sql); echo ""; echo " New Users "; echo " "; echo ""; Any ides ?

So I have a database that is structured like this: https://imgur.com/a/DdyTqiE Sample data: https://imgur.com/a/kYwmuO1 For each appointment, a student can have multiple categories, such as 'Academic Probation, Re-Admit' etc... I would like to loop through this table, and get a count of how many were 'is_no_show' and 'is_cancelled' per (unique) category with respect to 'scheduled_student_services.' For example, in the sample data, we see that the first appointment has 4 categories (Academic Probation, Entering Cohort Year 20051, First Generation, and Re-Admit'). Now one of these categories - Academic Probation matches up with what they were scheduled for - '1st Term Probation Advising'. And they cancelled this appointment, so we want the count of cancellations under Academic Probation to go up by 1. How would I approach this? I know I probably need to do two loops but I'm not sure the PHP syntax for this. Any suggestions or tips would be helpful. Thank you for your time!

Hi, I have created a quiz and the questions get read from a MySql database table. I am now wanting to stop it repeating questions, when I first started this I thougt it would be easy just create a column called Duplicate and everytime a question got pulled I would mark it in the databse. So it would only read questions that had a "0" in the DuplicateCol and after reading the question it would put a "1" in place of the "0" That would work, the problem being multiple people are using it so if a 1 is there they wont all get asked the question. Anyway that idea is a fail now, which is a shame because everything else worked. Im hoping someone can show me another way on stopping duplicates. when I created the quiz I created a registration, and login page which have there own table I then created another table for the questions with multiple columns ie " id, Question, Answer1, Answer2, Answer3, CorrectAnswer, DuplicateCol " I had a number on my form which is a random number that lets say is "6" will then pull the question from column id 6 Query = "select Question,Answer1,Answer2,Answer3,CorrectAnswer,DuplicateCol from Questions where DuplicateCol= '0' AND id='" + RandomN.Text + "'" Anyway im for the time being lost until someone can give me ideas please, The registration, login table looks like this id, Serial, Email, UserName, Location, UserScore, Activated, I was thinking of adding q1, q2, q3, q4, q5, etc etc and then somehow if a question got pulled in my questions table with id "6" then put a "1" in the column but I think it might be to hard to try and cross reference 2 tables. Any Ideas ?

Hi, I have a MySql query which currently looks like this Query = "select Question,Answer1,Answer2,Answer3,CorrectAnswer,id,Duplicate from Questions where id='" + RandomN.Text + "'" As you can see I have a table called 'Questions' which has several columns, Im using VB.NET I also have a textBox on a windows form called 'RandomN' What this does is it takes whatever number is in my textBox called RandomN.Text and looks for that number in the id column and returns all data on that row. What I am trying to acheive now is this, I have a column called Duplicate it will either contain the word 'True' or 'False' I would like it to only return data from the given number in the textBox if the Duplicate column in that row contains the word 'False' If someone can shed some light I would be greatful. Thanks

Hello Everyone - I am playing around with some MYSQL and PHP project I have. I ran into a complex problem getting a PHP table filled with data from MYSQL. I will try to explain what I am trying to do: I am trying to do something like this but in PHP. This is my data from MYSQL database. The Table is called Children This is a quick explanation of how each column on the first screenshot should be filled from the database. This code is what I have so far... to be honest i am not sure how to get the totals of rest of the columns. Maybe use I can use subqueries or if statements... not sure! Can you please help me out? $r = mysqli_query($dbc,"SELECT Classrooms.ClassroomName, COUNT(*) AS TotalChildren FROM Children JOIN Classrooms ON Children.classroomID = Classrooms.classroomID GROUP BY Classrooms.ClassroomName");

I'm a newbie, can you please help? I'm getting a mysql error "Unknown column 'E0000001' in 'where clause'" The id is in the URL: ...user-profile.php?id=E0000001 My Query $query = mysqli_query($con, "SELECT * FROM UserList WHERE UserID=".$id) or die (mysqli_error($con)); Thank you

I'm probably too close to see whats wrong, what do you see?

I'm on a new path here and would appreciate any ideas you pros might have. I think this involves triggers and another table but am not sure. I have a project record that has fields that contain information. It's important to know when some fields change. For example, I have a field call DRAWING which contains a link to a project print. Values in this link change whenever the print is modified. It's important to know the date of the last change. When the project page is opened for review, I want to show, to the right of this field (and a few others), the date/time is was last changed. I want the time information field based, not record based. My initial idea is to trigger after a record update and compare an 'identical' table against the project table. After checking the fields of interest for change I would write the project table associated lastupdate fields with a date and then overwrite this 'identical' table with the new state of things. This all could be done with code but it gets a bit onerous. I was hoping to do it once in a stored procedure. Comments? Thank you. 10.1.38-MariaDB

I was wondering if there is a way to automatically get a user's timezone? I want to show certain information if the user's current date is less than the expiry date. It works fine if the user is in a default timezone but what if the user is in a different timezone? How I can I make sure I can get their correct current time? date_default_timezone_set('America/New_York'); $expiry_date = trim($row['expiry_date']); $current_date = date('Y-m-d H:i:s'); if($current_date < $expiry_date) { // show data } else { // don't show }

select player_id,Gender,Shirt_no FROM player_details; +-----------+--------+----------+ | player_id | Gender | Shirt_no | +-----------+--------+----------+ | 10 | M | 34 | | 11 | M | 12 | | 12 | M | 13 | | 13 | M | 34 | +-----------+--------+----------+ 13 rows in set (0.00 sec) select player_id,Team_catId from players_team; +-----------+------------+ | player_id | Team_catId | +-----------+------------+ | 10 | 1 | | 12 | 2 | | 11 | 3 | | 13 | 1 | +-----------+------------+ i would like to put a check constraint on the shirt_no field,such that no player in same team category has same shirt number i have tried this: CREATE TABLE player_details ( player_id INT(11) UNSIGNED NOT NULL AUTO_INCREMENT, Fname VARCHAR(60) NOT NULL, Gender ENUM('M','F'), Shirt_no tinyint(2), PRIMARY KEY (player_id ), CONSTRAINT Shirt_number_taken CHECK (NOT EXISTS -- reference to second table (SELECT * FROM Soka_players_team_tbl AS M1 WHERE M1.player_id = Soka_player_details_tbl.player_id )) ); but it is not working.

i have this table structure and an array of new records, how can i run an update on all player ids with new ones for a particular matchid select player_id, MatchID,minutes from soka_player_statistics_tbl; +-----------+---------+---------+ | player_id | MatchID | minutes | +-----------+---------+---------+ | 1 | 29 | NULL | | 2 | 29 | NULL | | 3 | 29 | NULL | | 4 | 29 | NULL | | 5 | 29 | NULL | | 6 | 29 | NULL | | 7 | 29 | NULL | | 8 | 29 | NULL | | 9 | 29 | NULL | +-----------+---------+---------+ I have tried this : update soka_player_statistics_tbl set player_id=inPlayerId where MatchID=inMatchId; but if i run in an array from php to update matchID 29 with new player ids,i get an ERRNO: 256 TEXT: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '1-29' for key 'PRIMARY'
