I am working on a form that is used to send notifications. In the form, I have, among other fields, one input file field. In this field I upload a CSV file. From CSV (contains a column of email messages) I extract the data using https://code.google.com/p/jquery-csv/ and add it to the select readonly multiple field with all the options selected.
Note. I created a form using form forms (from Symfony2 book) - class NotificationType extends AbstractType ; The form is submitted via AJAX;
1. Beat one Considering that the field of choice is filled dynamically, I decided not to add it to the form designer, but to enter it using JavaScript.
This was a bad move, because when submitting a form, Symfony2 confirms that the fields added to the form builder are the exact ones that are submitted. Return error: this form should not contain additional fields.
2. Hit two. Moving from the strike, I wanted to see if I could get around this, so I added a selection box in the form builder, but without parameters, and also entered the options using JavaScript.
Still out of luck. Symfony2 also ensures that you cannot submit a parameter that was not added to the form designer when adding the field. Return error: this value is invalid.
3. Hit three From Strike 1 and 2, I assume that the only way to do this work is to add all the possible options in the form builder to the selection array when adding a field. Thus, the field and parameters will be valid for sending.
But this is not what I consider a viable option, especially because in the selection box I expect 10,000 possible results, which I donβt know about until I upload the CSV file.
Can any other approach be suggested for this?
Thanks!
