How to update a collection in MongoDB database using php?
Question
I have written a piece of code to take the values from a user through a form and updating the collection based on the product ID entered by the user. The piece of code works but doesn't produce the right results. I guess I'm not able to get/fetch the correct value of product ID that's why this is happening. Any help would be appreciated. Also I'm new to php and MongoDB.

You are using spaces in your array try removing the spaces and see if this works.
$doc=array('productid'=>$product_id,
'productname'=>$product_name,
'productdesc'=>$product_desc,
'productprice'=>$product_price,
'productstock'=>$product_stock,
'productimage'=>$product_image
);
You will also need to do same in your MongoDB collection and remove the spaces.
