I am new to drupal and am building an app for my brother's business as a test case to help me learn.
I just built a solution to opening an add content form and pre-populating some fields depending on a code entered by the user. To be specific, you enter a code allocated by the company to a property they manage and it opens an 'add new payment' node entry form and fills in the name of the owner and populates a select list widget for an entity reference field with just the charges for that property, so you can select which charge the payment is for.
I solved it (over two days!) bit by bit learning about each module as I went, so although it works, it has some weaknesses.
If I was to explain how I achieve this and ask about specific parts that I think might cause problems, that should be useful to others in the future, right?
If not, can you point me towards where I might be able to do this.
Thanks for your time.
