I am trying to pre-populate an entity reference with a specific game node, when a profile node is added; based on URL of the game the add button is on.
The game node I want to reference in profile node is in the URL of the profile's add page.
By using views to contextually filter, matching the first portion of the url (the game node title), with a game node. Then to be used as the field's select list.
Only selection in drop down would make it seem pre-populated.
Two content types - game - profile
*game nodes alias pattern is [node:title]. so just /game1/ , /game2/
I added an alias for each game node to go to the profile add page game1/add > node/add/profile game2/add > node/add/profile
Using Entityreference prepopulate module i use /node/add/game-profile/?field_gmeprfl_game_eref=[node:nid] to generate id to reference; the ? (question mark) prevents the [node:nid] from processing to an id. it stays literaly "/node/add/game-profile/?field_gmeprfl_game_eref=[node:nid]". if i take out the "?" it will process to the nid number.
If I use view entity reference list to contextual filter the game1 part of url against the nodes alias , there is not alias for me to add in contextual filter. (id prefer this way so my links look better than ?field_gmeprfl_game_eref=14
**i use d7 prepopulate entity reference node (?field_gmeprfl_game_eref=[node:nid]), i cant use ? with [node:id] as the ? prevents the tokens from processing. if i can do this and make urls the same as OP: id consider that also.
