I'm trying to add another field to the customer create form.

The following code troughs an error in the backend. The error is:

Class Magento\Customer\Model\Metadata\Form\String does not exist

or if I refresh the page it will change to:

The requested component ("string") is not found. Before using, you must add the implementation.

and back to the original error if i refresh again.

Any ideas as to what I have done wrong?


Try to change this line:

"input"    => "string",

to the:

"input"    => "text",

because a component with name 'string' not exist.

Then reinstall your module.

Note: if on uninstall process your module does not delete the attribute salesAssociate programmatically you should do-it-yourself. Useful link - Magento 2 How to uninstall attributes added by custom module?


You can change input type right in the eav_attribute table, just find your attribute by the attribute_code (it should be salesAssociate) and set its frontend_input value as text. I didn't check this solution, but it should help.


You can just update your install class and reinstall the module. Add the line:

$customerSetup->removeAttribute(\Magento\Customer\Model\Customer::ENTITY, "salesAssociate");

Before the:

$customerSetup->addAttribute(\Magento\Customer\Model\Customer::ENTITY, "salesAssociate", [ ....

Remove the record about your module from the setup_module table and execute command bin/magento setup:upgrade in the magento root folder.

  • So I can see it all now but it didn't save to the database for the customer any ideas? – Mark Aug 25 '16 at 14:35
  • @Mark Try to change the <select name="regulation" to the <select name="salesAssociate" because the name of your attribute is salesAssociate – Siarhey Uchukhlebau Aug 25 '16 at 14:40
