Displaying previously entered values
As Example 6-7 already sets the value attribute of the <input> elements from the array $formVars, there are no changes needed to display previously entered values; Example 6-7 uses $formVars when displaying the current values of clients from the customer table. By setting $formVars as a session variable, Example 6-7 displays the values passed back from the validation script with each <input> field.
