When just a single result is needed, then no loop should be used. Just fetch the row right away. In case you need to fetch the entire row into associative array: $row = $result->fetch_assoc(); in case you need just a single value $row = $result->fetch_row(); $value = $row[0] ?? false; The last example will return … Read more
I don’t know why, but with print_r I do get the results! print_r($row); Displays: Array ( [open_uitdagingen] => 3 ) So i did get the result, but why var_dump($res->fetch_assoc()); gives an empty result? I still don’t know, but i can go on now an that counts:) solved Stored procedure, no values returned? [closed]

As was said, if you’re merely going to skip the record then you may as well not retrieve them in the first place (and thus incur the overhead for having to extract them into PHP memory, etc): SELECT * FROM `your_table` WHERE `gender` = ‘female’ AND `taken` = `available`; However, if you have a specific … Read more

The following is wholly untested! The Object Orientated style of using mySQLi is considerably less verbose than the procedural style and alas your code is vulnerable to SQL injection due to the use of POST data directly used within the SQL statement. You should consider using Prepared Statements to mitigate this threat. It appears that … Read more
If you only want specific associative properties from all columns queried from the MySQL call, just set them in an array with their respective properties: $categoriesTest = array(); $sql = “SELECT * FROM `respondent_data` WHERE `respondent_firstname` = ‘John'”; $result = mysqli_query($conn, $sql); while($row = mysqli_fetch_assoc($result)) { $categoriesTest[] = array( ‘respondent_sdo’ => $row[‘respondent_sdo’], ‘respondent_dcto’ => $row[‘respondent_dcto’], … Read more
As suggested, prepared statements are the best way to achieve good protection from SQL injection. Shortened Example You will need to add entries to fill in all columns you wish to insert. $email = $_POST[‘e-mail’]; $fn = $_POST[‘firstname’]; $ln = $_POST[‘lastname’]; if ($stmt = $mysqli->prepare(“INSERT INTO `newcartdb`.`orders`(Email,Firstname,Lastname) values(?,?,?)”) { $stmt->bind_param(“sss”, $email, $fn, $ln); “sss” – … Read more

INT has a max value of 2147483647 (or 214-748-3647). So, 555-555-5555 will get rewritten to the max it can store. Phone numbers are NOT integers, so you shouldn’t store them like that. All sorts of problems can happen – 055-555-5555 would be stored incorrectly as 55-555-5555, 555-555-5555 x1234 can’t be entered, etc. 1 solved Issue … Read more
There are multiple issues with your current code. You fetch the first row with $row = mysqli_fetch_array($select); (line 3), but you don’t do anything with it. This means that the first result is discarded. Your while loop attempts to loop over an incorrect variable ($query is a string, not the result-object), and you’ve quoted it … Read more
