I'm in need of a skilled PHP/MySQL programmer to help me resolve issues with my legacy application. While the data in the current database isn't critical and can be easily recreated, the system is currently not allowing the addition or update of database records, although deletion is possible. Key requirements and responsibilities: - The main issue is resolving the problem of not being able to add or update database records. - There are no error messages displayed, so a deep understanding of PHP and MySQL is needed to identify and solve the root problem. - Once the issue is resolved, the next step would be to optimize the application to prevent similar issues in the future. Ideal skills: - Proficient in PHP and MySQL - Experience in working with and debugging legacy applications - Understanding of database management from webpages - Ability to optimize systems for future stability - Strong communication skills to explain technical issues clearly The project is on a debugging and optimization basis, so the work required should be based on the identified issues. Please bid with your experience in similar projects and how you plan to approach this task. I have fully documented both the module, as well as exactly where and when the "issues" arise.
