Unless you have removed some code to post it here, your PHP script never sets the variable "$submit", so the MySQL code would never get executed. Further, your script never retrieves the form data from $_POST, so there's no data to be stored in the database anyway.
If all of your validation checks in your javascript function pass there is no return value, so the return is undefined which is a falsy value in javascript. If all checks go through return a truthy value. If that doesn't work, then test certain parts of your script. For instance, echo the $submit var in your php script somewhere so you can see its value. Or even echo anything in your php script to see if it is getting that far. You can test the javascript in the same way. As rainborick said above, you will need to extract the post data in your php script before $submit or other form data have values.
Your code is running very properly i have cheked on my pc might be there is some problem with your data base or connection is not proper go through the connection of your data base.
Thanks for reply. I have changed if($submit) to if ($_POST['submit']) and i have extracted the data using these lines of code :- $matric = $_POST['matric']; $name = $_POST['name']; $sem=$_POST['sem']; $sex=$_POST['sex']; $tel=$_POST['tel']; $address=$_POST['address']; $data = $_POST['picture']; $course = $_POST['course']; PHP: But still i am not able to save picture in blob field. Everything else is being saved(course,address,matric,name etc.) in db except picture and its related info. Why image is not being saved in db ? I have stored blob in db while running another project. @php_developer How come the code is running perfectly on your machine. As rainborick and Ksnitro suggested my php code does not extract the data posted. Is it also saving blob ?
