html checkbox
<!-- You can also group multiple checkboxes by giving them the same "name". When posted to PHP, all the checked boxes' values will appear in the $_POST array under an index with the same name as your checkboxes. E.g. if we check "bananas" and "apples" below and post the form then our $_POST array will look something like this: ['fruit' => ['bananas', 'apples']] --> <form> <label> <span>Bananas</span> <input type="checkbox" name="fruit[]" value="bananas"> </label> <label> <span>Apples</span> <input type="checkbox" name="fruit[]" value="apples"> </label> <label> <span>Grapes</span> <input type="checkbox" name="fruit[]" value="grapes"> </label> <button type="submit">Submit</button> </form>
