Working With FormMail

The following instructions consist of excerpts of the official formmail documentation. The complete documentation may be found at http://www.scriptarchive.com/readme/formmail.html


FormMail is a universal WWW form to E-mail gateway that allows you to create form-to-email forms without CGI scripting. There is only one form tag that is required in order for this script to work with your existing forms. Other hidden configuration fields can also be used to enhance the operation of FormMail on your site.

Your copy of the formmail.pl script is located in your /var/www/html directory.

The FormMail.pl script itself does not have to be extensively configured in order to work. There are only two variables in the perl file which you will need to define along with changing the top line of your script to match the location of you Perl interpreter ( #!/usr/bin/perl )

$mailprog = '/usr/lib/sendmail -i -t';
This variable must define the location to your server's sendmail program. If this is incorrect, form results will not be mailed to you.

@referers = ('yourdomain.com','YOUR_IP');
This array allows you to define the domains on which you allow forms to reside and use this installation of FormMail. By placing yourdomain.com in the @referers array, this also allows www.yourdomain.com, ftp.yourdomain.com, any other http address with yourdomain.com in it and scriptarchive.com's IP address to access this script as well, so no users will be turned away.

@recipients = &fill_recipients(@referers);
If you wish to only allow e-mail addresses from the domain(s) specified in "@referers" to receive form results, you probably do not need to change this variable. However, if you get any 'Error: Bad/No Recipient' messages when running FormMail, you may have to revisit "@recipients" and make sure you have correctly listed all domains or configured this variable.

"@recipients" is an array of regular expressions defining all valid recipients that can be specified in your form. In order for an e-mail to be sent to the recipient defined in a form, the recipient e-mail address must match one of the elements in the "@recipients" array.

Simple Setup:
For the most simple setup, just place any domain name that you wish to send form results to in the "@referers" array. Note, however, that this allows those domains to also access your FormMail script and utilize it to process their own forms. Likely, this is what you intended anyway. If so, you can leave the "@recipients" line alone

Another alternative is to set "@recipients" to the actual addresses of the intended recipients, like so:

For a single recipient:
@recipients = ('^yourself\@yourdomain\.com');

For multiple recipients:
@recipients = ('^user1\@yourdomain\.com','^user2\@their\.domain\.com');


What is this ^ character, and why so many \'s?
In regular expressions, the ^ means "beginning of string". By default, FormMail places a $ at the end of the match, which means "end of string". By using both ^ and $ in regular expression matching, FormMail can match a string exactly. You only need to worry about including the ^, which is STRONGLY recommended for all regular expressions in the array.

The \ character is used to escape a character that otherwise means something special in regular expressions. For instance, you now see every '.' being escaped with a '\', as '.' means ANY CHARACTER, whereas '\.' requires that it match ONLY a period.

Your formmail script is now configured.

Form Configuration

The form action line should be:
<form action="POST" action="/cgi-bin/formmail.pl">

Below is a list of form fields you can use, as well as instauctions on how to implement them.

Necessary Form Fields:
There is only one form field that you must have in your form for FormMail to work correctly. This is the recipient field.

Field: recipient
Description: This form field allows you to specify to whom you wish for your form results to be mailed. Most likely you will want to configure this option as a hidden form field with a value equal to that of your e-mail address. You can include multiple recipients by separating the values with commas.

Syntax:
<input type=hidden name="recipient" value="email@your.host.com">
OR
<input type=hidden name="recipient" value="user@yourhost.com,user2@yourhost.com">

Optional Form Fields

Field: subject
Description: The subject field will allow you to specify the subject that you wish to appear in the e-mail that is sent to you after this form has been filled out. If you do not have this option turned on, then the script will default to a message subject: WWW Form Submission.

Syntax:
If you wish to choose what the subject is:
<input type=hidden name="subject" value="Your Subject">

To allow the user to choose a subject:
<input type=text name="subject">

Field: email
Description: This form field will allow the user to specify their return e-mail address. If you want to be able to return e-mail to your user, I strongly suggest that you include this form field and allow them to fill it in. This will be put into the From: field of the message you receive. If you want to require an email address with valid syntax, add this field name to the required field.

Syntax:
<input type=text name="email">

Field: realname
Description: The realname form field will allow the user to input their real name. This field is useful for identification purposes and will also be put into the From: line of your message header.

Syntax:
<input type=text name="realname">

Field: redirect
Description: If you wish to redirect the user to a different URL rather than having them see the default response to the fill-out form, you can use this hidden variable to send them to a pre-made HTML page. An example might be a page with something like "Thank you for your request, a sales associate will be in touch with you shortly".

Syntax: To choose the URL they will end up at:
<input type=hidden name="redirect" value="http://your.host.com/to/file.html">

To allow them to specify a URL they wish to travel to once the form is filled out:
<input type=text name="redirect">

Field: required
Description: You can now require for certain fields in your form to be filled in before the user can successfully submit the form. Simply place all field names that you want to be mandatory into this field. If the required fields are not filled in, the user will be notified of what they need to fill in, and a link back to the form they just submitted will be provided. To use a customized error page, see missing_fields_redirect

Syntax: If you want to require that they fill in the email and phone fields in your form, so that you can reach them once you have received the mail, use a syntax like:
<input type=hidden name="required" value="email,phone">

Field: env_report
Description: Allows you to have Environment variables included in the e-mail message you receive after a user has filled out your form. Useful if you wish to know what browser they were using, what domain they were coming from or any other attributes associated with environment variables. The following is a short list of valid environment variables that might be useful:

REMOTE_HOST Sends the hostname making the request.
REMOTE_ADDR Sends the IP address of the remote host making the request.
REMOTE_USER If server supports authentication and script is protected, this is the username they have authenticated as. (This is not usually set.)
HTTP_USER_AGENT The browser the client is using to send the request.

There are others, but these are a few of the most useful. For more information on environment variables, see:
The CGI Resource Index: Documentation: Environment Variables

Syntax: If you wanted to find the remote host and browser sending the request, you would put the following into your form:
<input type=hidden name="env_report" value="REMOTE_HOST,HTTP_USER_AGENT">

Field: sort
Description: This field allows you to choose the order in which you wish for your variables to appear in the e-mail that FormMail generates. You can choose to have the field sorted alphabetically or specify a set order in which you want the fields to appear in your mail message. By leaving this field out, the order will simply default to the order in which the browsers sends the information to the script (which is usually the exact same order as they appeared in the form.) When sorting by a set order of fields, you should include the phrase "order:" as the first part of your value for the sort field, and then follow that with the field names you want to be listed in the e-mail message, separated by commas. Version 1.6 allows a little more flexibility in the listing of ordered fields, in that you can include spaces and line breaks in the field without it messing up the sort. This is helpful when you have many form fields and need to insert a line wrap.

Syntax: To sort alphabetically:
<input type=hidden name="sort" value="alphabetic">

To sort by a set field order:
<input type=hidden name="sort" value="order:name1,name2,etc...">

Field: print_config
Description: print_config allows you to specify which of the config variables you would like to have printed in your e-mail message. By default, no config fields are printed to your e-mail. This is because the important form fields, like email, subject, etc. are included in the header of the message. However some users have asked for this option so they can have these fields printed in the body of the message. The config fields that you wish to have printed should be in the value attribute of your input tag separated by commas.

Syntax: If you want to print the email and subject fields in the body of your message, you would place the following form tag:
<input type=hidden name="print_config" value="email,subject">

Field: print_blank_fields
Version: 1.6 & Up
Description: print_blank_fields allows you to request that all form fields are printed in the return HTML, regardless of whether or not they were filled in. FormMail defaults to turning this off, so that unused form fields aren't e-mailed.

Syntax: If you want to print all blank fields:
<input type=hidden name="print_blank_fields" value="1">

Field: title
Description: This form field allows you to specify the title and header that will appear on the resulting page if you do not specify a redirect URL.
Syntax: If you wanted a title of 'Feedback Form Results':
<input type=hidden name="title" value="Feedback Form Results">

Field: return_link_url
Description: This field allows you to specify a URL that will appear, as return_link_title, on the following report page. This field will not be used if you have the redirect field set, but it is useful if you allow the user to receive the report on the following page, but want to offer them a way to get back to your main page.

Syntax:
<input type=hidden name="return_link_url" value="http://your.host.com/main.html">

Field: return_link_title
Description: This is the title that will be used to link the user back to the page you specify with return_link_url. The two fields will be shown on the resulting form page as:
return_link_title

Syntax:
<input type=hidden name="return_link_title" value="Back to Main Page">

Field: missing_fields_redirect
Description: This form field allows you to specify a URL that users will be redirected to if there are fields listed in the required form field that are not filled in. This is so you can customize an error page instead of displaying the default.

Syntax:
<input type=hidden name="missing_fields_redirect" value="http://your.host.com/error.html">

Field: background
Description: This form field allow you to specify a background image that will appear if you do not have the redirect field set. This image will appear as the background to the form results page.

Syntax:
<input type=hidden name="background" value="http://your.host.xxx/image.gif">

Field: bgcolor
Description: This form field allow you to specify a bgcolor for the form results page in much the way you specify a background image. This field should not be set if the redirect field is.

Syntax: For a background color of White:
<input type=hidden name="bgcolor" value="#FFFFFF">

Field: text_color
Description: This field works in the same way as bgcolor, except that it will change the color of your text.

Syntax: For a text color of Black:
<input type=hidden name="text_color" value="#000000">

Field: link_color
Description: Changes the color of links on the resulting page. Works in the same way as text_color. Should not be defined if redirect is.

Syntax: For a link color of Red:
<input type=hidden name="link_color" value="#FF0000">

Field: vlink_color
Description: Changes the color of visited links on the resulting page. Works in the same way as link_color. Should not be set if redirect is.

Syntax: For a visited link color of Blue:
<input type=hidden name="vlink_color" value="#0000FF">

Field: alink_color
Version: 1.4 & Up
Description: Changes the color of active links on the resulting page. Works in the same way as link_color. Should not be set if redirect is.

Syntax: For a active link color of Blue:
<input type=hidden name="alink_color" value="#0000FF">
