Get data attribute value in Symfony controller

Question

In my View, I have this hidden field

<input type="hidden" id="logoID" name="logoID" class="logoID" value="123">

I add additional data to it using data attribute via jQuery like this

$('.logoID').data('fileName', 'xyz.jpg')  
// adds data attribute to input element -> <input ... data-fileName='xyz.jpg' />

Now I need to retrieve this fileName inside my controller. I know I can get value of this hidden field by

$form['logoID']->getData();       // 123

But I also need the value of the data-attribute (fileName). How can I go about it? Any leads are much appreciated.

Try setting a JSON value to the `logoID` hidden field and in your controller use `json_decode()`. — yceruto, Aug 15 '17 at 17:02
@JasonRoman yes, I know I could send it as another hidden field, but I wanted to know if there was another way to do it.. — Niket Pathak, Aug 15 '17 at 17:07
@yceruto yeah, seems like a small hack. Although my form validation would get screwed up then. So, can't really implement it. Thanks anyway! — Niket Pathak, Aug 15 '17 at 17:11

data-attributes are not available directly by the PHP scripts. You need to send that value using another hidden input or retrieve the value with Jquery later and post it as data using Ajax.

What do you have against using another hidden field? I'm not understanding. – Jason Roman Aug 15 '17 at 17:20
@JasonRoman lol. Nothing really, I'm only searching if there exists another way to do it. – Niket Pathak Aug 15 '17 at 17:33
