I have a PHP webform that successfully receives all POST variables, yet when I run my INSERT statement through mysqli_query() nothing ends up in the MySQL table and no error is thrown. Table names, column names, and variable names have all been double-checked for typos, and I have echoed the resulting SQL string—though I am still not fully confident it is 100 % correct. I’d like you to: • review the current PHP snippet that builds and executes the query
