Custom Field No Longer Working

Hey guys –

Thanks for resposnding!

Here’s the code that I’m using. It’s being added by using the PHP Inserter plugin.

/**
* Custom Form Fields
*
* @param $form_id
*/

function give_myprefix_custom_form_fields( $form_id ) {

//Only display for a specific form;
//Remove “If” statement to display on all forms

?>
<div id=”give-referral-wrap”>
<label class=”give-label” for=”give-referral”><?php _e( ‘Who would you like

to donate to?:’, ‘give’ ); ?></label>

<textarea class=”give-textarea” name=”give_referral” id=”give-

referral”></textarea>
</div>
<?php

}

add_action( ‘give_purchase_form_after_personal_info’, ‘give_myprefix_custom_form_fields’, 10, 1 );

/**

*
* @description check for errors without custom fields
*
* @param $valid_data
* @param $data

function give_myprefix_validate_custom_fields( $valid_data, $data ) {

//Check that we’re validating the proper form
//Remove if this is a global field
if ( $data[‘give-form-id’] !== ‘754’ ) {
return;
}

//Check for a referral data
if ( empty( $data[‘give_referral’] ) ) {
give_set_error( ‘give_referral’, __( ‘Who would you like to donate to.’, ‘give’ )

);
}
}

add_action( ‘give_checkout_error_checks’, ‘give_myprefix_validate_custom_fields’, 10, 2 );

/**

function give_myprefix_store_custom_fields( $payment_meta ) {
$payment_meta[‘referral’] = isset( $_POST[‘give_referral’] ) ? implode( “n”, array_map(

‘sanitize_text_field’, explode( “n”, $_POST[‘give_referral’] ) ) ) : ”;

return $payment_meta;
}

add_filter( ‘give_payment_meta’, ‘give_myprefix_store_custom_fields’ );

/**

*
* @description show the custom field(s) on the transaction page

* @param $payment_meta

*/
function give_myprefix_purchase_details( $payment_meta, $user_info ) {

Hey guys – I made a mistake as to which form I’m having an issue with. It’s actually, the form on the home page not the one 1 posted above. I added the code you suggested but still receive {referral} in the email confirmation rather than the name of the person that is being donated to.

The code now looks like this:

/**
* Custom Form Fields
*
* @param $form_id
*/

function give_myprefix_custom_form_fields( $form_id ) {

//Only display for a specific form;
//Remove “If” statement to display on all forms

?>
<div id=”give-referral-wrap”>
<label class=”give-label” for=”give-referral”><?php _e( ‘Who would you like

to donate to?:’, ‘give’ ); ?></label>

<textarea class=”give-textarea” name=”give_referral” id=”give-

referral”></textarea>
</div>
<?php

}

add_action( ‘give_purchase_form_after_personal_info’, ‘give_myprefix_custom_form_fields’, 10, 1 );

/**
* Validate Custom Field
*
* @description check for errors without custom fields
*
* @param $valid_data
* @param $data
*/
function give_myprefix_validate_custom_fields( $valid_data, $data ) {

//Check that we’re validating the proper form
//Remove if this is a global field
if ( $data[‘give-form-id’] !== ‘754’ ) {
return;
}

//Check for a referral data
if ( empty( $data[‘give_referral’] ) ) {
give_set_error( ‘give_referral’, __( ‘Who would you like to donate to.’, ‘give’ )

);
}
}

add_action( ‘give_checkout_error_checks’, ‘give_myprefix_validate_custom_fields’, 10, 2 );

/**
* Add Field to Payment Meta
*
* @description store the custom field data in the payment meta
*
* @param $payment_meta
*

function give_myprefix_store_custom_fields( $payment_meta ) {
$payment_meta[‘referral’] = isset( $_POST[‘give_referral’] ) ? implode( “n”, array_map(

‘sanitize_text_field’, explode( “n”, $_POST[‘give_referral’] ) ) ) : ”;

return $payment_meta;
}

add_filter( ‘give_payment_meta’, ‘give_myprefix_store_custom_fields’ );

/**

*

*

function give_myprefix_purchase_details( $payment_meta, $user_info ) {

//uncomment below to see payment_meta array
// echo “

	//	var_dump($payment_meta);
	//	echo "

}

?>

}

/**

*
* @description Example function that returns Custom field data if present in payment_meta; the example used here is in conjunction with the Give documentation tutorials

*/
function my_custom_prefix_get_donation_referral_data( $tag_args ) {

$payment_meta = give_get_payment_meta( $tag_args[‘payment_id’] );
$output = __( ‘No referral data found.’, ‘give’ );

Thanks so much for your quick response!

I updated the code with what you have there but the plugin My Custom Functions says there a “fatal error” (sound dire -lol).
