Best way to check for end of a record and send it back to the first record

Posted on 16th Feb 2014 07:03 pm by admin

I'm hoping someone can help me out and explain the best way to accomplish this.

What I'm doing I'm pulling data from a data base. I display the information 1 item at a time then have a next and previous link to navigate forward or backward through the records.

The issue is when it gets to the last record and I press the next link i get errors cause their is no more records. so what I'm wondering what a good way to send it back to the first record? would it make sense to store the total number of records in a variable and then load the load the id's pulled from the database into an array and check against the end of the array for the end of the records and send it back to the first element of the array?

Any explanations are examples would be helpful even a link to somewhere showing this would be good. I haven't found one yet.
