When I hit one of the submit buttons I want to take the value of row[0] out into a flask app. The row values have come from an 3d array from the flask app, this block of html is looped over the columns. I want to receive the value of the location for that specific block that I clicked the submit button on so that I can move to a new page specifically about that location, and I don't want to user to see an input box. I'm confused and any help would be much appreciated, thanks.

CodePudding user response：

There are several things wrong with this. First, a "hidden" item is not going to be visible, so it should not have a list item (unless you want the user to see it). Second, if you want the hidden item to be called "location", then it's NAME needs to be location. The value is what you want sent back. So:

 <input type="hidden" name"location" value="{{row[0]}}">
