如何解决如何将php smarty下拉列表转换为按钮？

| 我需要帮助以将php smarty下拉菜单转换为按钮。 我正在尝试为订阅和取消订阅新闻通讯创建两个按钮。 请帮助。 PHP Smarty代码： 
private function isNewsletterRegistered($customerEmail)
{
    if (Db::getInstance()->getRow(\'SELECT `email` FROM \'._DB_PREFIX_.\'newsletter WHERE `email` = \\\'\'.pSQL($customerEmail).\'\\\'\'))
        return 1;
    if (!$registered = Db::getInstance()->getRow(\'SELECT `newsletter` FROM \'._DB_PREFIX_.\'customer WHERE `email` = \\\'\'.pSQL($customerEmail).\'\\\'\'))
        return -1;
    if ($registered[\'newsletter\'] == \'1\')
        return 2;
    return 0;
}

private function newsletterRegistration()
{
    if (empty($_POST[\'email\']) OR !Validate::isEmail(pSQL($_POST[\'email\'])))
        return $this->error = $this->l(\'Invalid e-mail address\');
    /* Unsubscription */
    elseif ($_POST[\'action\'] == \'1\')
    {
        $registerStatus = $this->isNewsletterRegistered(pSQL($_POST[\'email\']));
        if ($registerStatus < 1)
            return $this->error = $this->l(\'E-mail address not registered\');
        /* If the user ins\'t a customer */
        elseif ($registerStatus == 1)
        {
            if (!Db::getInstance()->Execute(\'DELETE FROM \'._DB_PREFIX_.\'newsletter WHERE `email` = \\\'\'.pSQL($_POST[\'email\']).\'\\\'\'))
                return $this->error = $this->l(\'Error during unsubscription\');
            return $this->valid = $this->l(\'Unsubscription successful\');
        }
        /* If the user is a customer */
        elseif ($registerStatus == 2)
        {
            if (!Db::getInstance()->Execute(\'UPDATE \'._DB_PREFIX_.\'customer SET `newsletter` = 0 WHERE `email` = \\\'\'.pSQL($_POST[\'email\']).\'\\\'\'))
                return $this->error = $this->l(\'Error during unsubscription\');
            return $this->valid = $this->l(\'Unsubscription successful\');
        }
    }
    /* Subscription */
    elseif ($_POST[\'action\'] == \'0\')
    {
        $registerStatus = $this->isNewsletterRegistered(pSQL($_POST[\'email\']));
        if ($registerStatus > 0)
            return $this->error = $this->l(\'E-mail address already registered\');
        /* If the user ins\'t a customer */
        elseif ($registerStatus == -1)
        {
            global $cookie;

            if (!Db::getInstance()->Execute(\'INSERT INTO \'._DB_PREFIX_.\'newsletter (email,newsletter_date_add,ip_registration_newsletter,http_referer) VALUES (\\\'\'.pSQL($_POST[\'email\']).\'\\\',NOW(),\\\'\'.pSQL(Tools::getRemoteAddr()).\'\\\',(SELECT c.http_referer FROM \'._DB_PREFIX_.\'connections c WHERE c.id_guest = \'.(int)($cookie->id_guest).\' ORDER BY c.date_add DESC LIMIT 1))\'))
                return $this->error = $this->l(\'Error during subscription\');
            $this->sendVoucher(pSQL($_POST[\'email\']));

            return $this->valid = $this->l(\'Subscription successful\');
        }
        /* If the user is a customer */
        elseif ($registerStatus == 0)
        {
            if (!Db::getInstance()->Execute(\'UPDATE \'._DB_PREFIX_.\'customer SET `newsletter` = 1,newsletter_date_add = NOW(),`ip_registration_newsletter` = \\\'\'.pSQL(Tools::getRemoteAddr()).\'\\\' WHERE `email` = \\\'\'.pSQL($_POST[\'email\']).\'\\\'\'))
                return $this->error = $this->l(\'Error during subscription\');
            $this->sendVoucher(pSQL($_POST[\'email\']));

            return $this->valid = $this->l(\'Subscription successful\');
        }
    }
}

private function sendVoucher($email)
{
    global $cookie;

    if ($discount = Configuration::get(\'NW_VOUCHER_CODE\'))
        return Mail::Send((int)($cookie->id_lang),\'newsletter_voucher\',Mail::l(\'Newsletter voucher\'),array(\'{discount}\' => $discount),$email,NULL,dirname(__FILE__).\'/mails/\');
    return false;
}

function hookfooter($params)
{
    global $smarty;

    if (Tools::isSubmit(\'submitNewsletter\'))
    {
        $this->newsletterRegistration();
        if ($this->error)
        {
            $smarty->assign(array(\'color\' => \'red\',\'msg\' => $this->error,\'nw_value\' => isset($_POST[\'email\']) ? pSQL($_POST[\'email\']) : false,\'nw_error\' => true,\'action\' => $_POST[\'action\']));
        }
        elseif ($this->valid)
        {
            if (Configuration::get(\'NW_CONFIRMATION_EMAIL\') AND isset($_POST[\'action\']) AND (int)($_POST[\'action\']) == 0)
                Mail::Send((int)($params[\'cookie\']->id_lang),\'newsletter_conf\',Mail::l(\'Newsletter confirmation\'),array(),pSQL($_POST[\'email\']),dirname(__FILE__).\'/mails/\');
            $smarty->assign(array(\'color\' => \'green\',\'msg\' => $this->valid,\'nw_error\' => false));
        }
    }
    $smarty->assign(\'this_path\',$this->_path);
    return $this->display(__FILE__,\'blocknewsletter.tpl\');
}
TPL文件代码： 
<div id=\"newsletter_block_left\" class=\"block\">
<h4>{l s=\'Newsletter\' mod=\'blocknewsletter\'}</h4>
<div class=\"block_content\">
{if isset($msg) && $msg}
    <p class=\"{if $nw_error}warning_inline{else}success_inline{/if}\">{$msg}</p>
{/if}
    <form action=\"{$link->getPageLink(\'index.php\')}\" method=\"post\">
        <p><input type=\"text\" name=\"email\" size=\"18\" value=\"{if isset($value) && $value}{$value}{else}{l s=\'your e-mail\' mod=\'blocknewsletter\'}{/if}\" onfocus=\"javascript:if(this.value==\'{l s=\'your e-mail\' mod=\'blocknewsletter\'}\')this.value=\'\';\" onblur=\"javascript:if(this.value==\'\')this.value=\'{l s=\'your e-mail\' mod=\'blocknewsletter\'}\';\" /></p>
        <p>
            <select name=\"action\">
                <option value=\"0\"{if isset($action) && $action == 0} selected=\"selected\"{/if}>{l s=\'Subscribe\' mod=\'blocknewsletter\'}</option>
                <option value=\"1\"{if isset($action) && $action == 1} selected=\"selected\"{/if}>{l s=\'Unsubscribe\' mod=\'blocknewsletter\'}</option>
            </select>
            <input type=\"submit\" value=\"ok\" class=\"button_mini\" name=\"submitNewsletter\" />
        </p>
    </form>
</div>
    

解决方法

        编辑：我使代码段更加具体，希望对您有所帮助 使用2个提交按钮 
<form action=\"{$link->getPageLink(\'index.php\')}\" method=\"post\">
    <p><input type=\"text\" name=\"email\" size=\"18\" value=\"{if isset($value) && $value}{$value}{else}{l s=\'your e-mail\' mod=\'blocknewsletter\'}{/if}\" onfocus=\"javascript:if(this.value==\'{l s=\'your e-mail\' mod=\'blocknewsletter\'}\')this.value=\'\';\" onblur=\"javascript:if(this.value==\'\')this.value=\'{l s=\'your e-mail\' mod=\'blocknewsletter\'}\';\" /></p>
    <p>
        <input type=\"submit\" value=\"unsubscribe\" class=\"button_mini\" name=\"submitNewsletterUnsubscribe\" />
        <input type=\"submit\" value=\"subscribe\" class=\"button_mini\" name=\"submitNewsletterSubscribe\" />
    </p>
</form>
在php中，测试是否设置了其中之一： 
private function newsletterRegistration()
{
    if (empty($_POST[\'email\']) OR !Validate::isEmail(pSQL($_POST[\'email\'])))
        return $this->error = $this->l(\'Invalid e-mail address\');
    /* Unsubscription */
    elseif (isset($_POST[\'submitNewsletterSubscribe\']))
    {
        /* ... */
    }
    /* Subscription */
    elseif (isset($_POST[\'submitNewsletterUnsubscribe\']))
    {
        /* ... */
    }
}
只有其中之一将被单击，因此只有其中之一将与表格一起发送。
