My background is primarily PHP, so i’m used to being able to use deep arrays in forms very easily. What I need is the c#/MVC equivelant of the following:
<input type="text" name="data[0][index_name][0]">
<input type="text" name="data[0][index_name][1]">
<input type="text" name="data[1][index_name][0]">
<input type="text" name="data[1][index_name][1]">
<input type="text" name="data[2][index_name][0][something_else]">
<input type="text" name="data[2][index_name][0]">
<input type="text" name="data[2][index_name][1]">
These could then be accessed in this way in php…
$_POST['data'][0]['index_name'][0];
$_POST['data'][0]['index_name'][1];
$_POST['data'][1]['index_name'][0];
$_POST['data'][1]['index_name'][1];
$_POST['data'][2]['index_name'][0]['something_else'];
$_POST['data'][2]['index_name'][0];
$_POST['data'][2]['index_name'][1];
I’ve tried looking at/looping over the formColletion object i receive, but the keys are simply the name attribute string, such as “data[2][index_name][0][something_else],” and there is no depth to the data.
How do I parse this data and put in some usable data type? I do not know how deep the array will be as the form changes dynamically on the front end.
So you have some context, this will is being used to build a “table” of data that has a flexible number of rows and columns and each row can be treated as a standard row or grouping row (meaning it contains other rows), so the data can, in theory, get very deep.
On a side note, i’ve also thought about cleaning up the data on the client side, but it appears there’s nothing standard out there that supports this. Jquery.serialize and JQuery.serializeArray() do the same thing as C#/MVC and simply index everything with the full name attribute without taking into account the array indexes.
Thanks for any help!
Model Binding turned out to be the correct solution. It support recursion out of the box. Here is a nice write-up:
