The following code parameters may be passed to the chat client launch script (chat.js) by configuring the addonchat_param variable as shown in the example below the table.

Code parameters are added just before var addonchat in your link code, or they can be placed just after the addonchat JavaScript object.

Code parameters will override your control panel settings, and any user settings that may have been saved within browser cookies. Depending upon your control panel settings, some items can be changed by the user after they have logged in.

Some parameters are only available with Professional PLUS or Enterprise edition chat rooms. Additionally, some clients (e.g., the iPhone mobile client) may only use a subset of the full code parameter list.

The following parameter types are used in code parameters:

• Boolean
  Boolean type entries (e.g., audio), should be specified as either true or false. Values of 1, "on", or "yes" may be used in place of true, and values of 0, "off", or "no" may be used in place of false.
• String
  String values may contain any valid ASCII or UTF-8 character code sequence. String values must be placed within quotation marks.
• Integer
  Positive or (if applicable) negative number. Integer values need not be placed within quotation marks.
• Dimension
  Positive integer to indicate a dimension (height or width) in pixels, or a percentage ("1%" to "100%") value. Percentage dimensions values must be enclosed in quotation marks.
• Color
  Color values should be in 6 digit RGB hexadecimal format; the same as used in the control panel. A leading hash (#) is required for the bgcolor and boxbgcolor parameters. Color values must be placed within quotation marks.
• Font
  Font values should be of the form Name-Style-Size; where Name is any valid system font name; Style is one of PLAIN, BOLD, ITALIC or BOLD+ITALIC; and size is a positive integer no larger than 48. Font values must be placed within quotation marks.
• URL
  URL values must be valid, fully qualified uniform resource locators. URL values typically contain world wide web site addresses. URL values must be placed within quotation marks.

The subroom_single parameter may only be used with Enterprise edition accounts. When used in conjunction with the autologin, username, and password parameters, the subroom parameter can be used to automatically sign a user in and place him/her in a specific room.

If you choose to make use of the the popup link, simple link or direct link (no website) options, you may also make use of code parameters by passing slightly modified URL-encoded code parameters as URL parameters. It's easy, and we've provided examples below:

The popup Link, simple Link and direct Link options all call a script called chat.php (or sc.php, or sc.pl in legacy codes which now all redirect to chat.php).

Parameter names passed to the direct link are the exact same as the standard code parameters except that they must all be prefixed with param_, with the exception of the additional optional parameters listed below:

If you are using the direct link (no website), we recommend that code parameters be kept to a minimum for clarity.

When using direct links, be certain to observe the following rules:

• Direct link code parameters should be prefixed with param_
  The only exception to this rule is when using one of the direct-link specific parameters listed above.
• Direct link code parameter values are never be enclosed in quotation marks.
• Direct link code parameters should be URL encoded.

Direct link code parameters may also be passed via the CGI POST method.
