Can you do the tasks within 20 hours please - Urgent?? Because its an urgent situation and I have other projects to work on. This task has to be done using PHP. I have given a short description of what is expected.
The add menu has to get details from user say, Departure stop, departure time, arrival stop and arrival time and duration has to calculated and all data has to be inserted to the database. Form validation has to be done for empty values and numeric bus number.
The update menu is as same say, the user has a form field asking for the bus number he wants to update and clicking the update gets him all the details for the bus number he entered. he can edit the details and then update it to the database. Check whether the entered bus number is in the database and if it is then the details have to be retrieved and displayed for updating. If no data found for the entered bus number an option to add the new route has to given to the user.
The same way as for the Delete function.
The last is the shortest route search where the user enters departure stop, departure time and arrival stop and the page has to display the possible shortest route as in the format given.
Sorry for writing long. Am bit anxious actually.
