Trying to send a hidden input value to next page - php

Question

I am trying to tweak Wordpress Jigoshop according to my customer's needs and I got a bit stuck. What I need is: when a product variation is selected, some additional options appear in the form of radio buttons which customers must chose. I've managed to get everything working, but what I need now is to send the selected radio button to the cart, checkout and so on when the submit button is clicked.
I am trying to use their product customization function to do this and their function is:
if (!function_exists('jigoshop_product_customize_panel')) {
function jigoshop_product_customize_panel() {
global $_product;
if ( isset( $_POST['Submit'] ) && $_POST['Submit'] == 'Save Personalization' ) {
$custom_products = (array) jigoshop_session::instance()->customized_products;
$custom_products[$_POST['customized_id']] = trim( wptexturize( $_POST['jigoshop_customized_product'] ));
jigoshop_session::instance()->customized_products = $custom_products;
}
if ( get_post_meta( $_product->ID , 'customizable', true ) == 'yes' ) :
$custom_products = (array) jigoshop_session::instance()->customized_products;
$custom = isset( $custom_products[$_product->ID] ) ? $custom_products[$_product->ID] : '';
$custom_length = get_post_meta( $_product->ID , 'customized_length', true );
$length_str = $custom_length == '' ? '' : sprintf( __( 'You may enter a maximum of %s characters.', 'jigoshop' ), $custom_length );
echo '<div class="panel" id="tab-customize">';
echo '<p>' . apply_filters('jigoshop_product_customize_heading', __('Enter your personal information as you want it to appear on the product.<br />'.$length_str, 'jigoshop')) . '</p>';
?>
<form action="" method="post">
<input type="hidden" name="customized_id" value="<?php echo esc_attr( $_product->ID ); ?>" />
<?php
if ( $custom_length == '' ) :
?>
<textarea
id="jigoshop_customized_product"
name="jigoshop_customized_product"
cols="60"
rows="4"><?php echo esc_textarea( $custom ); ?>
</textarea>
<?php else : ?>
<input
type="text"
id="jigoshop_customized_product"
name="jigoshop_customized_product"
size="<?php echo $custom_length; ?>"
maxlength="<?php echo $custom_length; ?>"
value="<?php echo esc_attr( $custom ); ?>" />
<?php endif; ?>
<p class="submit"><input name="Submit" type="submit" class="button-alt add_personalization" value="<?php _e( "Save Personalization", 'jigoshop' ); ?>" /></p>
</form>
<?php
echo '</div>';
endif;
}
}
I tried modifying their function to suit my needs and this is what I've come up with (where get_cod is the id and name of the hidden input and "Adauga in cos" is the value of my submit button):
if (!function_exists('salveaza_cod_material')) {
function salveaza_cod_material() {
global $_product;
if ( isset( $_POST['submit']) && $_POST('submit') == 'Adauga in cos') {
$custom_products = (array) jigoshop_session::instance()->customized_products;
$custom_products[$_POST['customized_id']] = trim( wptexturize( $_POST['get_cod'] ));
jigoshop_session::instance()->customized_products = $custom_products;
}
$custom_products = (array) jigoshop_session::instance()->customized_products;
$custom = isset( $custom_products[$_product->ID] ) ? $custom_products[$_product->ID] : '';
}}
However the value isn't sent to the next page. Can anybody please help? Cheers!
Here's an update containing more of the code:
<form action="<?php echo esc_url( $_product->add_to_cart_url() ); ?>" class="variations_form cart" method="post">
<fieldset class="variations">
<?php foreach ( $attributes as $name => $options ): ?>
<?php $sanitized_name = sanitize_title( $name ); ?>
<div>
<span class="select_label"><?php echo jigoshop_product::attribute_label('pa_'.$name); ?></span>
<select id="<?php echo esc_attr( $sanitized_name ); ?>" name="tax_<?php echo $sanitized_name; ?>">
<option value=""><?php echo __('Choose an option ', 'jigoshop') ?>…</option>
<?php foreach ( $options as $value ) : ?>
<?php if ( taxonomy_exists( 'pa_'.$sanitized_name )) : ?>
<?php $term = get_term_by( 'slug', $value, 'pa_'.$sanitized_name ); ?>
<option value="<?php echo esc_attr( $term->slug ); ?>"><?php echo $term->name; ?> </option>
<?php else : ?>
<option value="<?php echo esc_attr( sanitize_title( $value ) ); ?>"><?php echo $value; ?></option>
<?php endif;?>
<?php endforeach; ?>
</select>
</div>
<?php endforeach;?>
</fieldset>
<div id="piele-neagra" class="colors" style="display:none">
<ul class="materiale">
<li><input type="radio" name="piele-neagra" value="L73">
<p><img class="alignnone size-full wp-image-155" title="L73" src="http://www.scaune-directoriale.ro/wp-content/uploads/materiale/piele-neagra/L73.gif" alt="L73" width="72" height="72" /></p>
</li>
</ul>
</div>
<div id="stofa-mf" class="colors" style="display:none">
<ul class="materiale">
<li><input type="radio" name="tapiterie" value="MF01" />
...
<div id="stofa-rg" class="colors" style="display:none"> Stofa RG</div>
<div class="clear"></div>
<span id="cod_material"><?php echo esc_attr( $custom ); ?></span>
<span><?php echo trim( wptexturize( $_POST['get_cod'] )); ?></span>
<div class="single_variation"></div>
<?php do_action('jigoshop_before_add_to_cart_form_button'); ?>
<div class="variations_button" style="display:none;">
<input type="hidden" name="variation_id" value="" />
<input type="hidden" name="customized_id" value="<?php echo esc_attr( $_product->ID ); ?>" />
<input type="hidden" id="get_cod" name="get_cod" value="" />
<input type="hidden" name="product_id" value="<?php echo esc_attr( $post->ID ); ?>" />
<div class="quantity"><input name="quantity" value="1" size="4" title="Qty" class="input-text qty text" maxlength="12" /></div>
<input type="submit" id="submit_cart" class="button-alt" value="<?php esc_html_e('Add to cart', 'jigoshop'); ?>" />
</div>
<?php do_action('salveaza_cod_material'); ?>
<?php do_action('jigoshop_add_to_cart_form'); ?>
</form>
And this is the section of the cart that receives the value:
if ( !empty( $values['variation_id'] )) {
$product_id = $values['variation_id'];
} else {
$product_id = $values['product_id'];
}
$custom_products = (array) jigoshop_session::instance()->customized_products;
$custom = isset( $custom_products[$product_id] ) ? $custom_products[$product_id] : '';
if ( ! empty( $custom_products[$product_id] ) ) :
?>
<dl class="customization">
<dt class="customized_product_label"><?php echo apply_filters('jigoshop_customized_product_label', __('Personal: ','jigoshop') ); ?></dt>
<dd class="customized_product"><?php echo esc_textarea( $custom ); ?></dd>
</dl>
<? php
endif;
?>

It's just a typo: in if ( isset( $_POST['submit']) && $_POST('submit') == 'Adauga in cos'), replace $_POST('submit')by $_POST['submit']
