However, sometimes you might require a unique sku which is not a random number such as 8721054256023 which is the sort of number you get by using [cart]. For example, what if you are making an employee database and you want to track it using a logical progression (1, 2, 3 etc.) with each new employee's number being one higher than the last.Here is a snippet of code to take the highest sku value from a database and then increment it by one: [search db=yourdatabase.db&grskudata=0&skusort=1] [founditems] [name][math]newsku=[sku][/math] [/founditems] [/search] [math]newsku=(newsku+1)[/math]
Final value=[math]newsku[/math]
To hide the output from a [math][/math] context just enclose it like so This lets the code get parsed without displaying the results. To call the newsku value elsewhere in the template just use [math]newsku[/math] .....................................................................
