 *



 * Read This First



 * ~~~~~~~~~~~~~~~



 *  This script is very well documented and quite large!  It looks daunting,



 *  but really isn't.



 *  If you have experience with PHP or other scripting languages,



 *  here's what you *need* to read:



 *      - Configuration (TARGET_EMAIL & DEF_ALERT)



 *      - Creating Forms



 *  That's it!  (Alternatively, just read the Quick Start and/or



 *  Quicker Start section below).



 *  Full configuration documentation is here:



 *      http://www.tectite.com/fmdoc/index.php



 *



 *  NOTE: do not read or modify this script or any PHP script



 *  with DreamWeaver or FrontPage!



 *  Many versions of those programs silently corrupt PHP scripts.



 *



 * Purpose:



 * ~~~~~~~~



 *  To accept information from an HTML form via HTTP and mail it to recipients.



 *



 * What does this PHP script do?



 * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



 *  On your web site, you may have one or more HTML forms that accept



 *  information from people visiting your website.  Your aim is for your



 *  website to email that information to you and/or add it to a database.



 *  FormMail performs those functions.



 *



 * Quick Start



 * ~~~~~~~~~~~



 *  1. Edit this file and set TARGET_EMAIL for your requirements (near



 *      line 256 in this file - replace "yourhost\.com" with your mail server's



 *      name).  We also strongly recommend you set DEF_ALERT (the next



 *      configuration below TARGET_EMAIL).



 *  2. Install this file as formmail.php (or other name ending in .php)



 *     on your web server.



 *     Test alerts by using your browser to open a URL to the script:



 *          http://www.yourhost.com/formmail.php?testalert=1



 *     Alerts are the only way FormMail can tell you the details of



 *     errors or faults.



 *  3. Create an HTML form and:



 *      - specify a hidden field called "recipients" with the email address



 *        of the person to receive the form's results.



 *      - in the your form tag set the action attribute to



 *        the formmail.php you uploaded to your web server



 *



 *  Once you have FormMail working, you may be interested in some advanced



 *  usage and features.  We have HOW-TO guides at www.tectite.com which



 *  describe many of the advanced processing you can do with FormMail.



 *      http://www.tectite.com/fmhowto/guides.php



 *



 * Quicker Start



 * ~~~~~~~~~~~~~



 *  Use the FormMail Configuration Wizard here:



 *      http://www.tectite.com/wizards/fmconf.php



 *  By answering a few questions you'll get a configured FormMail and



 *  a sample HTML form ready to upload and use on your server.



 *



 * Features



 * ~~~~~~~~



 *  For a list of features go to: http://www.tectite.com/formmailpage.php



 *



 * Security



 * ~~~~~~~~



 *  Security is the primary concern in accepting data from your website



 *  visitors.



 *  Tectite FormMail has several security features designed into it.  Note,



 *  however, it requires configuration for your particular web site.



 *



 * Configuration



 * ~~~~~~~~~~~~~



 *  To configure this script, go to the section titled "CONFIGURATION"



 *  (after reading the legal stuff below).



 *



 *  There is only one mandatory setting: TARGET_EMAIL



 *  and one strongly recommended setting: DEF_ALERT



 *



 *  Full configuration information is available here:



 *      http://www.tectite.com/fmdoc/index.php



 *

    // Multi-page form sequencing is complicated....



    // Requirements:



    //      1. The first page in a multi-page form sequence must provide:



    //          - multi_start field set to 1



    //          - this_form field (it's own URL)



    //          - next_form field (multi-page form template name)



    //      2. Subsequent pages must provide either:



    //          next_form (the next template name in the sequence)



    //         OR



    //          good_url or good_template or neither; this terminates



    //          the multi-page processing and provides the final URL.



    // Logic:



    //      1. We create session variables to contain information about



    //         the sequence.



    //      2. On the first submission from the starting form, we record



    //         its "this_form" URL and the data submitted.



    //         We also create a URL (to FormMail) that will allow return



    //         to the *next* form in the sequence.



    //      3. On submission from other forms in the sequence, we record



    //         the data that was submitted so we can return to that



    //         form with the user's data re-filled into the form.



    //         We also create a URL (to FormMail) that will allow return



    //         to the *next* form in the sequence.



    //      4. A return URL contains "return=index" where index is the



    //         form sequence index number.  This is a URL to FormMail.



    //         FormMail gets the template name or URL (URL only for the



    //         starting form) and outputs the requested HTML form.  It also



    //         truncates the session data for forms after the returned-to



    //         one.
