Security Code Plug-in English Version

step1:
Install GD Perl module。

ppm> install GD

ppm> rep add NewRepSite http://theoryx5.uwinnipeg.ca/ppms/

ppm> search GD

ppm> install GD

Step2:
1)Download SCode plugin,extract it;

2)edit SCode.pm, modify "my $tmpdir" to temporary folder of your server, "my $scode_length" is the length of code, "my $scode_maxtmp" is the max number of security code generated at the same time, default is 50.
temporary folder must be given the right to write such as: c:/website/mt/tmp/

3)Modify "mt-scode.cgi", $c_background,$c_border, $c_line, $c_code is the color of the Security Code.

4)Upload SCode.pm to the folder lib/MT/, scode.pl to folder plugins/, mt-scode.cgi to root folder of MT, and give mt-scode.cgi right to executable.

5)open lib/MT/App/Comments.pm, find

if (!$q->param('text')) {
return $app->handle_error($app->translate("Comment text is required."));
}

add following code after above:

#
# SecurityCode hack start
#
require MT::SCode;
my $code = $q->param('code');
my $scode = $q->param('scode');
my $sscode = MT::SCode::scode_get($code);
if ($scode ne $sscode) {
return $app->handle_error($app->translate(
"Wrong or missing Security Code."));
}
MT::SCode::scode_delete($code);
MT::SCode::scode_create($code);
#
# Security hack ends
#

6)Open lib/MT/Template/Context.pm, find "_hdlr_comment_fields" function,

sub _hdlr_comment_fields { my ($ctx, $args, $cond) = @_;

after that add following:

# Security code validation
srand int (time/10)+$$;
my $securitycode = int rand(MT::SCode::scode_tmp()); $securitycode++;
MT::SCode::scode_create($securitycode);
# End Security code hack

find another two place:

<MT_TRANS phrase="Remember me?">
<input type="radio" id="remember" name="bakecookie" />

add following code after them:

<!-- Security Code Check --> <input type="hidden" id="code" name="code" value="$securitycode" /> <label for="scode">Security Code:</label><br /> <img border="0" alt="Please enter the security code you see here" src="$path/mt-scode.cgi?code=$securitycode" /><br /> <input tabindex="3" id="scode" name="scode" /><br /><br /> <!-- end of Security Code Check -->

7)Edit Individual Entry Archive, under

<label for="url">URL</label><br />
<input tabindex="3" id="url" name="url" /><br /><br />

please add following:

<!-- Security Code Check --> <label for="scode">SCode:</label><br /> <input type="hidden" id="code" name="code" value="<$MTSecurityCode$>" /> <img border="0" src="<$MTCGIPath$><$MTSecurityImage$>?code=<$MTSecurityCode$>"><br /> <input tabindex=3 id="scode" name="scode" /><br /><br /> <!-- end of Security Code Check -->

8) Now, rebuild your Blog, the Security code appears.
