need to test if sql query was successful

Question

I have this query and if it returns successful, I want another function to process, if not, do not process that function.

Here is the code for running the query

Answer 1

You can use this to check if there are any results ($result) from a query:

if (mysqli_num_rows($result) != 0)
 {
  //results found
 } else {
  // results not found
 }
