Thanks - correct the email was encrypted originally but now this is left unencrypted for the query - other personal data is encrypted. I removed the duplicate select statement - code updated above. To fix the $post vulnerability you suggest bind in your post here - codereview.stackexchange.com/questions/230940/… - is this therefore the fix i require? — OnTarget 47 secs ago

Unfortunately this is the wrong site for code reviews. However, there is another site in the Stack Exchange network: codereview.stackexchange.com - you'll need to read the guidelines to see what's expected, but... that site seems like a much better fit. — David Makogon 40 secs ago

@MadPhysicist Please keep in mind that on Code Review the code must be working as expected before we can review it. There is a how to question in the post that makes it off-topic for code review. This question has already landed in the Close Vote Queue on CR as well. We can't tell the OP how to save the image at a higher size than their screen resolution. — pacmaninbw 5 secs ago

Welcome to Stack Overflow. Please read How to Ask and stackoverflow.com/help/on-topic and stackoverflow.com/help/dont-ask. We don't take code review requests here; try Code Review, but keep in mind that you will still need to ask a much more specific question than "what are your thoughts about this code?". — Karl Knechtel 34 secs ago
