passing data to controller

Question

I am passing data from below sample .phtml file to controller:

<form name="sendsms" action="<?php $params = [];
echo $block->getUrl("admin_sms/Sendsms/SendSMS", $params); ?>" method="POST">
    Mobile Number: <input class="input-text admin__control__text" type="text" name="mobile_number"><br>
    Message Body :<textarea class="input-text admin__control__text" name="message_body"></textarea><br>
    <input type="submit" name="send_sms" class="ui-button-text" value="send SMS"><br>
</form>

Below is a controller:

<?php

namespace Vendor\module_name\Controller\Adminhtml\Sendsms;

use Magento\Backend\App\Action;

class SendSMS extends Action
{
    protected $_resultForwardFactory;

    /**
     * @param \Magento\Backend\App\Action\Context $context
     */
    public function __construct(
        \Magento\Backend\App\Action\Context $context
    )
    {
        parent::__construct($context);
    }

    /**
     * Forward to edit
     *
     * @return \Magento\Backend\Model\View\Result\Forward
     */
    public function execute()
    {
        echo "execute";
        die();
    }
}

Block file contains below getUrl function:

public function getUrl($route = '', $params = [])
{
    return $this->_urlBuilder->getUrl($route, $params);
}

When I am trying to submit form, it keep getting redirected to dashboard in admin panel.

Answer 1

Avoid declaring the $params array inside the action of <form> tag.

Also use $this->getUrl() instead of $block->getUrl()

Try this instead

<?php 
$params = [];
<form name="sendsms" action="<?php echo $this->getUrl("admin_sms/Sendsms/SendSMS",$params);?>" method="POST">
Mobile Number: <input class="input-text admin__control__text" type="text" name="mobile_number" /><br/>
Message Body :<textarea  class="input-text admin__control__text" name="message_body"></textarea><br/>
<input type="submit" name="send_sms" class="ui-button-text" value="send SMS"/><br/>
</form>
