What is PhpDig?
PhpDig is a PHP MySQL based
Web Spider & Search Engine.
fdf_set_opt — Sets a value in the opt array for a
bool fdf_set_opt(fdfdoc, fieldname, element, value, name);
resource fdfdoc: FDF
string fieldname: Field
int element: Element
string value: Element
string name: Element
TRUE on success; FALSE on error
Sets the value of one element in a field's /Opt key. If
the field doesn't exist in the FDF, it's created. If it
exists, and already has an /Opt array, the requested
element in the array is replaced.
Existing since version 4.0.2
Example 288. Build list-box
values for the "MyListBox" field
// create the FDF
$outfdf = fdf_create();
// set a dafault value
fdf_set_value($outfdf, "volume", $volume, 0);
// set a list of dropbox options for a field named 'MyListBox'
// in this case a list of languages
fdf_set_opt($fdf, "MyListBox", 0, "X", "Please choose your language option");
fdf_set_opt($fdf, "MyListBox", 1, "E", "English");
fdf_set_opt($fdf, "MyListBox", 2, "S", "Spanish");
fdf_set_opt($fdf, "MyListBox", 3, "G", "German");
fdf_set_opt($fdf, "MyListBox", 4, "F", "French");
// save and display FDF file
$fp = fopen("outtest.fdf", "r");
