Custom input field on Woocommerce Single Product Page - wordpress

Question

I'm hopping someone can help me figure out how to add a custom text field to my single woocommerce product page.
I simply want to add a form and found this plugin, but it's not customizable. I much rather create the form and place it where I need it.

You Can try This, This will work 100%,
// Display Fields (function.php)
function woo_add_custom_general_fields() {
global $woocommerce, $post;
echo '<div class="options_group">';
// Custom fields will be created here...
echo '</div>';
}
add_action( 'woocommerce_product_options_general_product_data', 'woo_add_custom_general_fields' );
To create a text field type, you will need to use that code:
// Text Field
woocommerce_wp_text_input(
array(
'id' => '_text_field',
'label' => __( 'My Text Field', 'woocommerce' ),
'placeholder' => 'http://',
'desc_tip' => 'true',
'description' => __( 'Enter the custom value here.', 'woocommerce' )
)
);
To create a textarea, here is the code to use:
// Textarea
woocommerce_wp_textarea_input(
array(
'id' => '_textarea',
'label' => __( 'My Textarea', 'woocommerce' ),
'placeholder' => '',
'description' => __( 'Enter the custom value here.', 'woocommerce' )
)
);
Saving Fields Values:
function woo_add_custom_general_fields_save( $post_id ){
// Text Field
$woocommerce_text_field = $_POST['_text_field'];
if( !empty( $woocommerce_text_field ) )
update_post_meta( $post_id, '_text_field', esc_attr( $woocommerce_text_field ) );
// Textarea
$woocommerce_textarea = $_POST['_textarea'];
if( !empty( $woocommerce_textarea ) )
update_post_meta( $post_id, '_textarea', esc_html( $woocommerce_textarea ) );
}
// Save Fields
add_action( 'woocommerce_process_product_meta', 'woo_add_custom_general_fields_save' );
Display Custom Field Value
<?php
// Display Custom Field Value
echo get_post_meta( $post->ID, 'my-field-slug', true );
// You can also use
echo get_post_meta( get_the_ID(), 'my-field-slug', true );
?>
