How can I set a default value to show for a taxonomy term name in its edit form?

Question

I have a site where I have a taxonomy term. I want to set a default value to the term name and display it when the form loads. In hook_form_alter(), I tried to set the default value to Check term name in the form. The form loads with this value, but even after changing the value in the text field, the form gets submitted with Check term name.

This is the code I am using to set the default value.

$form['name']['widget'][0]['value']['#value'] = 'check term name';

How do I set the default value?

Answer 1

As @Kevin and @Clive noted, you must use #default_value to do this.

$form['name']['widget'][0]['value']['#default_value'] = 'check term name';

[Property] #default_value:

Description: The value of the form element that will be displayed or selected initially if the form has not been submitted yet. Should NOT be confused with #value, which is a hard-coded value the user cannot change!
