The name of the callback function to use

If we should pass variables instead of an array

Creates a new TFormDisplay element (for displaying information or read-only fields)

• string $name: The name of the database field to use
• string $displayname: The name that should show up to the user for this field.
• string $callback: The name of a callback function to use. Should accept one parameter, which will be an associative array containing: "name" ($name), "value" (of field), "table" (table for form), "keyfield" (keyfield for form), "keyidvar" (name of variable with id), and "keyid" (key value). Should return the exact text to display, including any html formatting.
• array $additional: Any additional values that should be passed to the callback function.
• bool $passVars: True if the paramters ($additional) should be passed as individual values. By default, one array is passed, and a number of other variables (name, value, table, keyfield, keyidvar, keyid) are introduced. When this is true, one of the paramaters should be "\$this->getValue()", which will be the value of the field (as a string, as it will be eval()'d). As an example, to display a field "Created" (INT, storing unix timestamp) via PHP's date() function, use: new TFormDisplay("Created", "Created", "date", array("M d Y","\$this->getValue()"), true)
