There are two ways to allow your contacts to forward your email to more than one friend or colleague at once. The first would be to simply add this additional line of code to your custom form, then create a text box as the email input:
<input type="hidden" name="multi" value="1">
Email addresses can be separated by carriage returns, commas, semi-colons, or spaces.
The second way would be to have each email address on a separate line. This may be preferable to you from a design perspective. In addition, you can include first and last name inputs for friends — a feature not available with the simpler 'multi' input. The ability to include first and last names will allow you to further customize the message that is sent to the friend.
In order to utilize multi-line inputs for FTAF, add this additional line of code to your custom form:
<input type="hidden" name="multi_extended" value="1">
Inputs for email addresses of the friends would look something like this:
Friend #1: <input type="text" name="email_1">
Friend #2: <input type="text" name="email_2">
Friend #3: <input type="text" name="email_3">
Friend #4: <input type="text" name="email_4">
Friend #5: <input type="text" name="email_5">
Note that the name for each input is 'email' followed by an underscore and a number. This number begins with '1' and increases for each input that is created. The maximum number of email inputs you can have in multi-extended FTAF is 32.
Inputs for first and last name follow the same format as the code above. If you would like to create a text box where the contact can enter their friend's first name, that input would be called 'first.' The input for the last name would be called 'last.' Again, when you are using multi-extended FTAF, input names must be followed by an underscore and a number that starts with '1' and increases for each input that is created.
For example:
First Name(s):
Friend #1: <input type="text" name="first_1">
Friend #2: <input type="text" name="first_2">
Friend #3: <input type="text" name="first_3">
Friend #4: <input type="text" name="first_4">
Friend #5: <input type="text" name="first_5">
Last Name(s):
Friend #1: <input type="text" name="last_1">
Friend #2: <input type="text" name="last_2">
Friend #3: <input type="text" name="last_3">
Friend #4: <input type="text" name="last_4">
Friend #5: <input type="text" name="last_5">
