With Label
Adds a setting with id
myprefix_setting-id
to the General Settings page.myprefix
should be a unique string for your plugin or theme. Sets a label so that the setting title can be clicked on to focus on the field.I suspect Used in the ‘id’ attribute of tags might be rewritten to Used in the ‘name’ attribute of tags.
I think the $id param is used for identifying the field to be recognised by WP and to show the field or get that’s value. Whether to be used as actual tag’s attribute id‘s value or not depends on the circumstances (in $callback). Normally the name attribute might be taken for this aim.
I just had been confused this param means to generate the attribute for some form element, but it seems not. When put ‘label_for’ in the $args that will be passed to the $callback, this generates label tag with attribute for automatically. So this value should be same as an actual id‘s value in the $callback which you write.
