as shown in the title, I have a page for users to create projects and another page to add it into my database. However when I press submit with the form fields empty, the page it post to isn’t blank. But when I submit with the fields filled up, it just shows be a blank page without any errors and I have looked through both pages of codes but can’t seem to find anything wrong. Perhaps someone here could help me out? Thanks.

I managed to solve the problem. When querying into the database, at my SELECT statement, the variables I forgot to add ”. E.g SELECT * FROM project WHERE project_title = ‘$variable’;
Anyways. thanks for those who helped out. I really appreciate it.
