Background: itemfuncs, form_options() and html_header_location()

Since we started deal with both php 4.1.x and with increasing code complexity we felt in need to create smarter ways to accomplish repetitive tasks without replicating the same code more and more. Functions described in this document had been created to achieve those goals.
Both all three group of functionalities described in this document had been created by Alessandro Pisani.
If you need more info or you have suggestions about them, you can find his email address at the end of this document.

Safe HTML redirection with html_header_location()

The html_header_location() function is a wrap around the PHP function header() in its most common use: header("Location: url"); (where url is a destination URL). html_header_location() provides compatibility with the different behaviour of the PHP costruct in different browsers (like Microsoft InternetExplorer 5.5 and above, Mozilla 0.9.8 and above, ...) and different versions of PHP.

Function prototype: function html_header_location($url)
Required parameters:

Return: this function does not return
Location: htmlheader.php (phpWebSite 0.8.1-CVS feb 2002)

Create menus and radio-boxes with form_options()

form_options() is an automated way to generate HTML input-radio and select-option selections in HTML forms. The function assumes the form is opened and closed respectively before and after it is called.

	$title = "Test form";
        $content = "<form method=\"post\" action=\"admin.php\">\n";
        $content .= form_options(0,"option","test_yesno",array("1","TRANSLATE[[Yes]]","0","TRANSLATE[[No]]"), 1);

	thememainbox($title,$content);
