Magento – Magento 2 save grid data from admin form

adminmagento2product-griduicomponent

I added a grid in admin form using UI Component by following the answer given here How to create Grid in Tabs?

Now when I save the data, I don't get the values of selected items in save controller.

Can someone tell me how to save this grid data?

Please see my code.

app/code/Vendor/Module/view/adminhtml/ui_component/vendor_module_blog_form.xml

<?xml version="1.0" ?>

I have faced the same issue while I am saving data, selected items not getting in the save controller.

I have used this tutorial @ https://www.rohanhapani.com/magento-2-how-to-add-product-grid-in-ui-form-using-uicomponent/

Solution:

Add UI component form name in "data-form-part" below file

app/code/Vendor/Module/view/adminhtml/templates/products/assign_products.phtml

<input type="hidden" name="rh_products" data-form-part="custom_form" id="rh_products" value=""  />

to

<input type="hidden" name="rh_products" data-form-part="ui_component_form_name" id="rh_products" value=""  />

may be it will help you for finding solution.

Magento – Magento 2: Plugin class does not exist

I'd experienced the same issue and after spending hours researching this I finally fixed it.

Could you tell me how did you deploy the module on production? Was it using the composer or FTP upload? IF it was composer, then I'd suggest reviewing it and making sure that it has the following information in your autoload section:

  "autoload": {
    "psr-4": {
        "Vendor\\ModuleName\\": ""
    },
    "files": [
        "registration.php"
    ]
}

You will need to add psr-4 to make it work. You can read more here: https://www.shoaibrehman.com/solved-fix-magento-2-plugin-class-vendormodulenameplugin-doesnt-exist/

Let me know if updating your composer file fixed the issue :)
