I am a PHP/MySQL deverloper and am ONLY interested in someone with actual experience in custom coding (PHP) in Joomla 1.5

I have a custom table with data entered through a form in Joomla
id - SubissionID - FieldName - FieldValue
1 - 1 - FirstName - Mike
2 - 1 - LastName - Smith
3 - 1 - UserID - 52
4 - 2 - FirstName - John
5 - 2 - LastName - Doe
6 - 2 - UserID - 53

I am displaying each SubmissionID in a row.
Mike Smith - Edit - Delete
John Doe - Edit - Delete

What YOU need to do:
1. On clicking Edit, it should take the visitor to a form that will display the FieldValue s and the visitor can change the value and submit.
Upon submit the data should update in the MySQL table.
Basically run SQL Update.....WHERE SubmissionID = ?

2. On clicking Delete, it should pop up a message that says "Are you sure you want to delete this record ?", with YES and CANCEL buttons.
Clicking YES will delete the particular record.
Basically run DELETE ....WHERE SubmissionID = ?
Clicking CANCEL will do nothing.

All the data were originally entered by members (CB is used).
Members should be able to delete only the data they themselves inserted before.
The funcationality to add the data is already done. So you don't need to do that.

So your code will need to make sure the records being deleted belongs to the member.
For instance if you send the SubmissionID through the URL
and then
DELETE ....WHERE SubmissionID = $_GET['SubmissionID']
That could be a PROBLEM.

Any programmer can easily throw in a different SubmissionID on the URL and delete and update records that they are not supposed to.

Therefore, your code must validate if the records belong to the member (UserID).

OK, that's a lot of technical details.
I am sure it's not a tough job for the right candidate.

I have some more much tougher work.

Please provide Joomla 1.5 custom work examples.
