Sure, there are a few reasons why submitted data from Node.js might be undefined in the MySQL database:

  • The data is not being entered correctly. Make sure that the data is being entered in the correct format and that the values are not exceeding the maximum length of the columns in the MySQL database.
  • The data is not being escaped correctly. Make sure that the data is being escaped before it is inserted into the MySQL database. This will help prevent SQL injection attacks.
  • The data is not being committed to the MySQL database. Make sure that the data is being committed to the MySQL database after it is inserted. This will ensure that the data is actually stored in the database.

Here are some steps you can take to troubleshoot why submitted data from Node.js is undefined in the MySQL database:

  1. Check the data that is being entered. Make sure that the data is being entered in the correct format and that the values are not exceeding the maximum length of the columns in the MySQL database.
  2. Check the escaping of the data. Make sure that the data is being escaped before it is inserted into the MySQL database. You can use the escape() method of the mysql module to escape the data.
  3. Check the commit of the data. Make sure that the data is being committed to the MySQL database after it is inserted. You can use the commit() method of the mysql module to commit the data.

If you have checked all of these things and the submitted data from Node.js is still undefined in the MySQL database, then you can try the following:

  • Restart the MySQL server.
  • Clear the MySQL cache.
  • Contact your system administrator for help.
