How to submit a form from custom phtml in Magento 2

Question

I have created a custom module and I have a custom phtml file with a form.

I have also created a new table for this module.

What I want to do is to insert the value of form in the DB But I actually don't know the flow for that.

What I mean is how can I send my form to a controller and then access the model to make operations?

Can anyone help my with an example how to do that?

Thank you in advance!

Answer 1

You need to create controller first and add it on form action.

Then in controller you can get form values by :

$name = $this->getRequest()->getPostValue("name"); // here i have taken example for name field

Then same way you need to create model and resource model to store data in your custom table.

Answer 2

In custom phtml, form action you have to give your controller url.

Below is the example :

<form name="form_sample" id="form_sample" enctype="multipart/form-data" action="<?php echo $this->getUrl() . 'sample/index/save'; ?>" method="post">

In controller, you can get the value and save into the db.

Example:

//Getting the form values

$data = $this->getRequest()->getParams();

//Save into db

$model = $this->obectManager->create('vendor/modulename/model/sample');
$model->setData($data);
$model->save();
