Yes, its a very useful Plug-In. Thank you :-)

Short Question: If the checkbox is not clicked, instead of "Please agree to.." it says
"Fatal error: Call to undefined method WooCommerce::add_error() " and the offended line is "$woocommerce->add_error( __('Please agree to my checkbox.') );" ..... Any Ideas?? Thanks for any Help :-)

Where in the function.php must I place this code. I only need a accepted checkbox for the terms of delivery etc 'I have read and agreed', very simple

Thanks for this! Just a little note: I had to change $woocommerce->add_error() to wc_add_notice('my error message', 'error' ); to make it work with WooCommerce 2.3.*

Can anyone help with this? I am trying to add a check box or radio button at checkout for the parent to choose which child they are registering for. The children information has been added to the parents profile using custom fields. Is there anyway for woocommerce to auto pull each child name so the parent can choose which child they are signing up and also have this displayed in the email thats sent out? Some parents may only have one kid some may have 4.

Thanks!

Hi there,

I am having problem with this code. If I copy it in full it breaks my site. If I edit it to remove the error message piece of the code, it works on the front end, but I do not receive notification in the order notes.

Thanks if you can help!

@maltehelmhold

also for me throwing:
SyntaxError: Unexpected token < in JSON at position 0

if it's not clicked. instead of "Please agree to my checkbox."

I can not find any other tutorial how to solve this task manually (without installing
an extra plugin)

I was getting an internal server error with the code above after my latest update. Fixed by changing $woocommerce->add_error to wc_add_notice (see comment by eduardo-marcolino above).

Hi,

i try change location checkbox to woocommerce_checkout_after_terms_and_conditions.

When i change:

* Add checkbox field to the checkout **/ add_action('**woocommerce_checkout_after_terms_and_conditions**', 'my_custom_checkout_field');

i have error:

Fatal error: Call to a member function get_value() on string in

in line:

), $checkout->get_value( 'my_checkbox' ));

What is wrong?

@GamerDamian
woocommerce_checkout_after_terms_and_conditions does not pass in the $checkout variable, so you cant call a function on nil
see woocommerce hooks

@dmcanaveral

If the checkbox isn't checked and throws an error, the form won't submit after it has been checked and the place order button is clicked again. It keeps throwing the error message. Any ideas?

Hello, I have tried this code snippit and found that if I leave a required field blank, I get an Internal Server Error. I am wondering what I can do to clear this up? Here is the code in my functions.php:

/** Add checkbox field to the checkout
**/
add_action('woocommerce_after_order_notes', 'my_custom_checkout_field');

function my_custom_checkout_field( $checkout ) {

echo '<div id="my-new-field"><h3>'.__('Mail List: ').'</h3>';

woocommerce_form_field( 'my_checkbox', array(
    'type'          => 'checkbox',
    'class'         => array('input-checkbox'),
    'label'         => __('Please add my email address to your mail list to keep me up to date on future offerings.'),
    'required'  => false,
    ), $checkout->get_value( 'my_checkbox' ));

echo '</div>';

}

/**

  • Process the checkout
    **/
    add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');

function my_custom_checkout_field_process() {
global $woocommerce;

// Check if set, if its not set add an error.
if (!$_POST['my_checkbox'])
     $woocommerce->add_error( __('Would you like to join the mail list?') );

}

/**

  • Update the order meta with field value
    **/
    add_action('woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta');

function my_custom_checkout_field_update_order_meta( $order_id ) {
if ($_POST['my_checkbox']) update_post_meta( $order_id, 'My Checkbox', esc_attr($_POST['my_checkbox']));
}

For those of you getting the error with get_value on an array -- use WC_Checkout::get_value instead

Hello,

works perfectly, thank you very much!

However, could you help me adapt this code to put the checkout in two more languages? I am using WPML.

Thanks again.
