计数已选中复选框（数组）编号并保存选中的复选框

Question

I have an array of checkbox in a table in PHP file like this :

echo "<td $Blocked><input type =\"checkbox\" name=\"Blocked[]\" value=\"checkblock\" /></td>";

I am trying to get the value of number of checked checkboxes and save it to DB.

$Blocked = 'unchecked';

if ((isset($_POST['edit_tc']))) {
    if (isset($_POST['Blocked'])) {
        if (is_array($_POST['Blocked'])) {
            foreach($_POST['Blocked'] as $value) {
                error_log($value);
            }
        }
        else {
            $value = $_POST['Blocked'];
            error_log($value);
        }

        $Blocked = 'checked';
    }
}

"edit_tc" is the Submit button.

How do I take the number of it when the user checks the checkbox & clicks Submit button to save it to a table column?

I guess below code will solve all your problem.

<?php
$hello = array();
if(isset($_POST['submit'])) {
  extract($_POST);
  print_r($hello); //print all checked elements
}
?>

<form method="post">
    <input type="checkbox" name="hello[]" value="1" <?php if(in_array(1, $hello)){ echo 'checked'; } ?>>
    <input type="checkbox" name="hello[]" value="2" <?php if(in_array(2, $hello)){ echo 'checked'; } ?>>
    <input type="checkbox" name="hello[]" value="3" <?php if(in_array(3, $hello)){ echo 'checked'; } ?>>
    <input type="checkbox" name="hello[]" value="4" <?php if(in_array(4, $hello)){ echo 'checked'; } ?>>
    <button type="submit" name="submit" value="Submit">Submit</button>
</form>

You have to check the value of each checkbox inside the checkbox array you are getting using in_arrayfunction of PHP.

If you need to understand whole thing, just let me know.

Will be glad to help you out.
