Get value from selection in a row

Get value from selection in a row

PalmoSweetPalmoSweet Posts: 13Questions: 0Answers: 0

Hi, I try to fetch values from rows in my datatable and it works great for the cells that contains strings, but the one contains a selection returns the source code. How can I only fetch the value of the selection?

<?php
    session_start();

    if(!isset($_SESSION["usersuid"])) {
        header("location: ../index.php");
    }

    $serverName = "localhost:3306";
    $dBUsername = "qderbntl_packageapple";
    $dBPassword = "zMWQH},bo?k]";
    $dBName = "qderbntl_db";

    $conn = mysqli_connect($serverName, $dBUsername, $dBPassword, $dBName);

    if (!$conn) {
        die("Connection failed: " . mysqli_connect_error());
    }

<?php
>
?>

This is my return in console:
(4) ['Svenska 2', 'SVESVE02', '100', '<select size="1" id="row-1-office" name="row-1-off…on>\n </select>']
0

"Svenska 2"
1

"SVESVE02"
2

"100"
3

"<select size=\"1\" id=\"row-1-office\" name=\"row-1-office\">\n ((this is the one that gives me source code))

This is how the datatable looks:

    You will want to use jQuery for this. Maybe something like this:

                $('#example tbody').on( 'click', 'tr', function () {
                    var d = table.row( this ).data();
          
                    console.log( $( d[3] ).find(":selected").text() ); 
                    console.log( $( d[3] ).find(":selected").val() );
     
                })
    

    You may need to use a different technique to find the selected value. Stack Overflow will have lots of ideas you can try, such as this thread.
