    FormMail and file upload

    How can I get an email alert when someone uploads a photo to my website?
    I really hope someone can help me with this. The "upload.cgi" script below works nicely on its own, and allows people to upload photos to a folder on my server. However, I now need to receive an email alert when someone uploads a photo. I have tried to add the contents of "upload.cgi" to Form Mail.pl and although it emails me the details of the file uploaded, the actual file has not uploaded to my folder. Any ideas on what would make it work? I can post the FormMail script I use as well if you need it. Thanks so much in advance for any help!
    upload.cgi:
    Code:
    #!/usr/bin/perl -w 
    use CGI; 
    use CGI::Carp qw/fatalsToBrowser warningsToBrowser/;
    $upload_dir = "../public_html/uploads/"; 
    my $query = new CGI;
    print $query->header();
    warningsToBrowser(1);
    print $query->start_html();
    $filename = $query->param("photo"); 
    $email_address = $query->param("email_address"); 
    $filename =~ s/.*[\/\\](.*)/$1/; 
    $upload_filehandle = $query->upload("photo"); 
    open UPLOADFILE, ">$upload_dir/$filename"; 
    binmode UPLOADFILE; 
    while ( <$upload_filehandle> ) 
    { 
    print UPLOADFILE; 
    } 
    close UPLOADFILE; 
    print <<END_HTML; 
    <HEAD> 
    <TITLE>Thanks!</TITLE> 
    </HEAD> 
    <BODY> 
    <P>Thanks for uploading your photo</P> 
    </BODY> 
    END_HTML
    print $query->end_html();

    Thank you for helping. Ok, here is the one I have 'modified' (I am no.t a developer or a programmer, so don't laugh! ). I hightlighted the bits I added in red. Also, I have changed my email address to a generic one for the purposes of posting the script here.

    =head1 DESCRIPTION
    This module is a base class for the C<CGI::NMS::Script::*> modules,
    which implement plugin replacements for Matt Wright's Perl CGI
    scripts.
    =head1 CONSTRUCTORS
    =over
    =item new ( CONFIG )
    Creates a new C<CGI::NMS::Script> object and performs compile time
    initialisation.
    CONFIG is a key,value,key,value list, which will be stored as a hash
    within the object, under the name C<CFG>.
    =cut
    sub new {
    my ($pkg, @cfg) = @_;
    my $self = bless {}, $pkg;
    $self->{CFG} = {
    DEBUGGING => 0,
    emulate_matts_code => 0,
    secure => 1,
    locale => '',
    charset => 'iso-8859-1',
    style => '',
    cgi_post_max => 1000000,
    cgi_disable_uploads => 1,
    $self->default_configuration,
    @cfg
    };
    $self->{Charset} = CGI::NMS::Charset->new( $self->{CFG}{charset} );
    $self->init;
    return $self;
    }
    =back
    =item CONFIGURATION SETTINGS
    Values for the following configuration settings can be passed to new().
    Subclasses for different NMS scripts will define their own set of
    configuration settings, but they all inherit these as well.
    =over
    =item C<DEBUGGING>
    If this is set to a true value, then the error message will be displayed
    in the browser if the script suffers a fatal error. This should be set
    to 0 once the script is in service, since error messages may contain
    sensitive information such as file paths which could be useful to
    attackers.
    Default: 0
    =item C<name_and_version>
    The name and version of the NMS script, as a single string.
    =item C<emulate_matts_code>
    When this variable is set to a true value (e.g. 1) the script will work
    in exactly the same way as its counterpart at Matt's Script Archive. If
    it is set to a false value (e.g. 0) then more advanced features and
    security checks are switched on. We do not recommend changing this 
    variable to 1, as the resulting drop in security may leave your script
    open to abuse.
    Default: 0
    =item C<secure>
    When this variable is set to a true value (e.g. 1) many additional
    security features are turned on. We do not recommend changing this
    variable to 0, as the resulting drop in security may leave your script
    open to abuse.
    Default: 1
    =item C<locale>
    This determines the language that is used in the format_date() method -
    by default this is blank and the language will probably be English.
    Default: ''
    =item C<charset>
    The character set to use for output documents.
    Default: 'iso-8859-1'
    =item C<style>
    This is the URL of a CSS stylesheet which will be used for script
    generated messages. This should probably be the same as the one that
    you use for all the other pages. This should be a local absolute URI
    fragment. Set C<style> to 0 or the empty string if you don't want to
    use style sheets.
    Default: '';
    =item C<cgi_post_max>
    The variable C<$CGI::POST_MAX> is gets set to this value before the
    request is handled.
    Default: 1000000
    =item C<cgi_disable_uploads>
    The variable C<CGI::DISABLE_UPLOADS> gets set to this value before
    the request is handled.
    Default: 1
    =item C<no_xml_doc_header>
    If this is set to a true value then the output_cgi_html_header() method
    will omit the XML document header that it would normally output. This
    means that the output document will not be strictly valid XHTML, but it
    may work better in some older browsers.
    Default: not set
    =item C<no_doctype_doc_header>
    If this is set to a true value then the output_cgi_html_header() method
    will omit the DOCTYPE document header that it would normally output.
    This means that the output document will not be strictly valid XHTML, but
    it may work better in some older browsers.
    Default: not set
    =item C<no_xmlns_doc_header>
    If this is set to a true value then the output_cgi_html_header() method
    will omit the C<xmlns> attribute from the opening C<html> tag that it
    outputs.
    =back
    =head1 METHODS
    =over
    =item request ()
    This is the method that the CGI script invokes once for each run of the
    CGI. This implementation sets up some things that are common to all NMS
    scripts and then invokes the virtual method handle_request() to do the
    script specific processing.

    =head1 VIRTUAL METHODS
    Subclasses for individual NMS scripts must provide the following
    methods:
    =over
    =item default_configuration ()
    Invoked from new(), this method must return the default script
    configuration as a key,value,key,value list. Configuration options
    passed to new() will override those set by this method.
    =item init ()
    Invoked from new(), this method can be used to do any script specific
    object initialisation. There is a default implementation, which does
    nothing.
    =cut
    sub init {}
    =item handle_request ()
    Invoked from request(), this method is responsible for performing the
    bulk of the CGI processing. Any fatal errors raised here will be
    trapped and treated according to the C<DEBUGGING> configuration setting.

    These C<validate_*> methods all return undef if the item passed
    in is invalid, otherwise they return the valid item.
    Some of these methods attempt to transform invalid input into valid
    input (for example, validate_abs_url() will prepend http:// if missing)
    so the returned valid item may not be the same as that passed in.
    The returned value is always detainted.

    =head1 DESCRIPTION
    This module implements the NMS plugin replacement for Matt Wright's
    FormMail2.pl CGI script.
    =head1 CONFIGURATION SETTINGS
    As well as the generic NMS script configuration settings described in
    L<CGI::NMS::Script>, the FormMail2 constructor recognizes the following
    configuration settings:
    =over
    =item C<allow_empty_ref>
    Some web proxies and office firewalls may strip certain headers from the
    HTTP request that is sent by a browser. Among these is the HTTP_REFERER
    that FormMail2 uses as an additional check of the requests validity - this
    will cause the program to fail with a 'bad referer' message even though the
    configuration seems fine.
    In these cases, setting this configuration setting to 1 will stop the
    program from complaining about requests where no referer header was sent
    while leaving the rest of the security features intact.
    Default: 1
    =item C<max_recipients>
    The maximum number of e-mail addresses that any single form should be
    allowed to send copies of the e-mail to. If none of your forms send
    e-mail to more than one recipient, then we recommend that you improve
    the security of FormMail2 by reducing this value to 1. Setting this
    configuration setting to 0 removes all limits on the number of recipients
    of each e-mail.
    Default: 5
    =item C<mailprog>
    The system command that the script should invoke to send an outgoing email.
    This should be the full path to a program that will read a message from
    STDIN and determine the list of message recipients from the message headers.
    Any switches that the program requires should be provided here.
    For example:
    'mailprog' => '/usr/lib/sendmail -oi -t',
    An SMTP relay can be specified instead of a sendmail compatible mail program,
    using the prefix C<SMTP:>, for example:
    'mailprog' => 'SMTP:mailhost.your.domain',
    Default: C<'/usr/lib/sendmail -oi -t'>
    =item C<postmaster>
    The envelope sender address to use for all emails sent by the script.
    Default: ''
    =item C<referers>
    This configuration setting must be an array reference, holding a list 
    of names and/or IP address of systems that will host forms that refer
    to this FormMail2. An empty array here turns off all referer checking.
    Default: [] 
    =item C<allow_mail_to>
    This configuration setting must be an array reference.
    A list of the email addresses that FormMail2 can send email to. The
    elements of this list can be either simple email addresses (like
    'you@your.domain') or domain names (like 'your.domain'). If it's a
    domain name then any address at that domain will be allowed.
    Default: []
    =item C<recipients>
    This configuration setting must be an array reference.
    A list of Perl regular expression patterns that determine who the
    script will allow mail to be sent to in addition to those set in
    C<allow_mail_to>. This is present only for compatibility with the
    original FormMail2 script. We strongly advise against having anything
    in C<recipients> as it's easy to make a mistake with the regular
    expression syntax and turn your FormMail2 into an open SPAM relay.
    Default: []
    =item C<recipient_alias>
    This configuration setting must be a hash reference.
    A hash for predefining a list of recipients in the script, and then
    choosing between them using the recipient form field, while keeping
    all the email addresses out of the HTML so that they don't get
    collected by address harvesters and sent junk email.
    For example, suppose you have three forms on your site, and you want
    each to submit to a different email address and you want to keep the
    addresses hidden. You might set up C<recipient_alias> like this:
    %recipient_alias = (
    '1' => 'one@your.domain',
    '2' => 'two@your.domain',
    '3' => 'three@your.domain',
    );
    In the HTML form that should submit to the recipient C<two@your.domain>,
    you would then set the recipient with:
    <input type="hidden" name="recipient" value="2" />
    Default: {}
    =item C<valid_ENV>
    This configuration setting must be an array reference.
    A list of all the environment variables that you want to be able to
    include in the email.
    Default: ['REMOTE_HOST','REMOTE_ADDR','REMOTE_USER','HTTP_USER_AGENT']
    =item C<date_fmt>
    The format that the date will be displayed in, as a string suitable for
    passing to strftime().
    Default: '%A, %B %d, %Y at %H:%M:%S'
    =item C<date_offset>
    The empty string to use local time for the date, or an offset from GMT
    in hours to fix the timezone independent of the server's locale settings.
    Default: ''
    =item C<no_content>
    If this is set to 1 then rather than returning the HTML confirmation page
    or doing a redirect the script will output a header that indicates that no
    content will be returned and that the submitted form should not be
    replaced. This should be used carefully as an unwitting visitor may click
    the submit button several times thinking that nothing has happened.
    Default: 0
    =item C<double_spacing>
    If this is set to 1 then a blank line is printed after each form value in
    the e-mail. Change this value to 0 if you want the e-mail to be more
    compact.
    Default: 1
    =item C<join_string>
    If an input occurs multiple times, the values are joined to make a
    single string value. The value of this configuration setting is
    inserted between each value when they are joined.
    Default: ' '
    =item C<wrap_text>
    If this is set to 1 then the content of any long text fields will be
    wrapped at around 72 columns in the e-mail which is sent. The way that
    this is done is controlled by the C<wrap_style> configuration setting.
    Default: 0
    =item C<wrap_style>
    If C<wrap_text> is set to 1 then if this is set to 1 then the text will
    be wrapped in such a way that the left margin of the text is lined up
    with the beginning of the text after the description of the field -
    that is to say it is indented by the length of the field name plus 2.
    If it is set to 2 then the subsequent lines of the text will not be
    indented at all and will be flush with the start of the lines. The
    choice of style is really a matter of taste although you might find
    that style 1 does not work particularly well if your e-mail client
    uses a proportional font where the spaces of the indent might be
    smaller than the characters in the field name.
    Default: 1
    =item C<address_style>
    If C<address_style> is set to 0 then the full address for the user who filled
    in the form will be used as "$email ($realname)" - this is also what the
    format will be if C<emulate_matts_code> is true.
    If it is set to 1 then the address format will be "$realname <$email>".
    Default: 0
    =item C<force_config_*>
    Configuration settings of this form can be used to fix configuration
    settings that would normally be set in hidden form fields. For
    example, to force the email subject to be "Foo" irrespective of what's
    in the C<subject> form field, you would set:
    'force_config_subject' => 'Foo',
    Default: none set
    =item C<include_config_*>
    Configuration settings of this form can be used to treat particular
    configuration inputs as normal data inputs as well as honoring their
    special meaning. For example, a user might use C<include_config_email>
    to include the email address as a regular input as well as using it in
    the email header.
    Default: none set

    =head1 COMPILE TIME METHODS

    the new() call is placed inside a BEGIN block as shown above.

    Re: FormMail and file upload

    The answer may be as simple as this.
    Code:
    use CGI; 
    use CGI::Carp qw/fatalsToBrowser warningsToBrowser/;
    my $upload_dir = "../public_html/uploads/"; 
    my $query = new CGI;
    print $query->header();
    
    Try changing my $upload_dir = "../public_html/uploads/"; to my $upload_dir="~/public_html/uploads/"; This would force the directory to the user's $HOME directory first. The ../ reference could be possibly misconstrued where the ~/ won't be.

    If that doesn't get it, I'll delve a little deeper. If it does, I should have caught it sooner.

    Re: FormMail and file upload

    Rosy,
    Have you looked into the formail documentation to see if it supports attachments.
    Otherwise, your best option is to use a module that supports attachments, I suggest Mime::Lite
    http://search.cpan.org/dist/MIME-Lite/lib/MIME/Lite.pm

    Use Mime::Lite, and create a HTML form with a file input.
