Hi guys

I am after a pre written PHP script or a tutorial which displays records from a table each with a checkbox. ( I have worked to this part)

When the check box is ticked and the submit button is pressed, the records with a checkbox get inserted into another table.

Any tutorial or script or webpage to guide me would be greatly appreciated.

I am not a coder but can study scripts and adapt and apply to my personal projects.

I'm curious what the output looks like if you were to do print_r($checkbox); on line 3 of your PHP file, immediately after setting the value of $checkbox to what's in POST (above your foreach loop).

Thank you, using a mish mash of tutorials, I have an almost 90% working solution.

Problem: When the checkboxes are selected, all records (unchecked) ones are also inserted.

My HTML file has a drop down value and a checkbox:

<input type="checkbox" name="checkbox[<?php echo $row['user_id']; ?>]">

My PHP file:

$checkbox = $_POST['checkbox'];
$class_id = trim($_POST['class_id']);



foreach ($checkbox as $key => $value) {
      echo "{$key} => {$value} ";


    //print_r($checkbox);

    $sql = "INSERT INTO Class_List (user_id,class_id) VALUES (?, ?)";

    if($stmt = mysqli_prepare($link, $sql)){

        mysqli_stmt_bind_param($stmt, "ii", $value, $class_id);


    if(mysqli_stmt_execute($stmt)){
        echo "";

    } else{
        echo "ERROR in inserting records: $sql. " . mysqli_error($link);

When I print the Checkbox Array I get:

6 => on Array ( [6] => on [7] => on )
Array
(
    [6] => on
    [7] => on
)
7 => on Array ( [6] => on [7] => on )
Array
(
    [6] => on
    [7] => on
)

I have not worked with Arrays so not sure what this output means.

Any helpp will be greatly appreciated,
