Generate an e-mail on page-not-found (404) errors [support thread]

I got tired of scouring my Apache logs for 404 errors, so wrote this little update that will send an e-mail to the address of your choice as part of the page_not_found processing.

Installation is short and simple (see the readme). You'll need to edit /includes/languages/english/YOURTEMPLATE/page_not_found.php to contain your desired e-mail address.

See download here: http://www.zen-cart.com/downloads.php?do=file&id=1090

Re: Generate an e-mail on page-not-found (404) errors

If you have a Google WebmasterTools account, there's a neat little report in there listing all the URLs that Google finds as 'not found' and all the pages that have those links on.

Most of the time, the list will contain URLs for removed products, but it's worth a scan every now and again.

Re: Generate an e-mail on page-not-found (404) errors

Thanks for the info, g1smd. My focus for developing this little add-on was more to get a notification for accesses that are likely someone groping around my site, of the like

www.example.com/admin

... when I've followed the security guidelines and renamed that folder.

Re: Generate an e-mail on page-not-found (404) errors

OK. That works too. :smile:

Additionally, I like to add this in the .htaccess file in the /admin/ folder:

Code:

Order Deny,Allow Deny from all Allow from 11.22.33

which allows access from a small range of IP addresses.

Re: Generate an e-mail on page-not-found (404) errors

Oops! There was an error in the first release (the observer class was not being instantiated).

I've just uploaded v1.1 to correct the error in class.emailFor404.php from

Code:

function emailFor404() { if (SEND_404_ERRORS_EMAIL_TO_STATUS == '1' and SEND_404_ERRORS_EMAILS_TO != '') { $this->attach($this, array('NOTIFY_HEADER_END_PAGE_NOT_FOUND')); } }

to

Code:

function emailFor404() { global $zco_notifier; if (SEND_404_ERRORS_EMAIL_TO_STATUS == '1' and SEND_404_ERRORS_EMAILS_TO != '') { $zco_notifier->attach($this, array('NOTIFY_HEADER_END_PAGE_NOT_FOUND')); } }

Re: Generate an e-mail on page-not-found (404) errors

The $this-> approach will work fine in 1.3.9 and newer.
For 1.3.8 and older you may have to use the old $zco_notifier-> approach instead.

Email on 404 (page-not-found) errors [support thread]

I've updated this add-on to v1.2 (http://www.zen-cart.com/downloads.php?do=file&id=1090), including a switch to enable/disable the archiving of these emails.

email body text not included in email

Hi,
Just tried out this latest version on ZC 1.5.

I receive the email but the text is not passed, its always:

Quote:

A 404 Error Was Generated

$EMAIL_MESSAGE_HTML

Strangely the email is in html format irrespective of the format chosen in the admin.
I get the same results with an (almost) vanilla 1.5 installation.
It tried it local/Xampp and remote hosting, same result.

regards
Steve

Re: email body text not included in email

I'm having a devil of a time replicating this. I've tried changing my CHARSET to utf-8 (which I'm assuming you're using), tried running as a logged-in or guest customer, changing my admin email format from HTML to Text and back. Regardless of these settings, I'm always receiving a Text-format message:

Code:

A user at host address [xxxx] with IP address [yyyy] generated a 404 using the query string [/index.php?main_page=elsewhere].

The settings in my Configuration->Email Settings are

Code:

E-Mail Transport Method PHP E-Mail Linefeeds LF Use MIME HTML When Sending Emails true

What are your email settings?

Re: email body text not included in email

torvista, would you try this updated version of /includes/classes/class.emailFor404.php and let me know if it works?

Code:

<?php class emailFor404 extends base { /** constructor method ! * * Attach observer class to the global $zco_notifier and watch for a single notifier event. */ function emailFor404() { global $zco_notifier; if (SEND_404_ERRORS_EMAIL_TO_STATUS == '1' and SEND_404_ERRORS_EMAILS_TO != '' and SEND_404_ERRORS_EMAILS_TO != '[email protected]') { $zco_notifier->attach($this, array('NOTIFY_HEADER_END_PAGE_NOT_FOUND')); } } /** Actual Method that does the desired activity * * Called by observed class when any of the notifiable events occur * * @param object $class * @param string $eventID */ function update(&$class, $eventID, $paramsArray = array()) { // BOF Send email to admin for 404 errors $email_text = sprintf(EMAIL_PAGE_NOT_FOUND_CONTENT, $_SESSION['customers_host_address'], $_SESSION['customers_ip_address'], $_ENV['REQUEST_URI'])."\n\n"; $email_subject = EMAIL_PAGE_NOT_FOUND_SUBJECT; $module = (SEND_404_ERRORS_EMAILS_ARCHIVE != '0') ? 'default' : 'no_archive'; $html_msg['EMAIL_SUBJECT'] = EMAIL_PAGE_NOT_FOUND_SUBJECT; $html_msg['EMAIL_MESSAGE_HTML'] = str_replace('\n','',$email_text); zen_mail('', SEND_404_ERRORS_EMAILS_TO, $email_subject, $email_text, STORE_NAME, EMAIL_FROM, $html_msg, $module); // EOF Send email to admin for 404 errors } } ?>

Re: email body text not included in email

Got it! If the email address to which the 404 emails are to be sent was used as a test-customer account email and that customer account uses HTML email settings, the email described by torvista will be sent. I've submitted v1.2.1 to the plugins area to correct the problem and describe how the HTML/TEXT emails will be sent.

Re: email body text not included in email

Thank you for your kind words! Here's the entire updated "update" function in the class module:

Code:

function update(&$class, $eventID, $paramsArray = array()) { // BOF Send email to admin for 404 errors $email_text = sprintf(EMAIL_PAGE_NOT_FOUND_CONTENT, $_SESSION['customers_host_address'], $_SESSION['customers_ip_address'], $_ENV['REQUEST_URI'])."\n\n"; $email_subject = EMAIL_PAGE_NOT_FOUND_SUBJECT; $module = (SEND_404_ERRORS_EMAIL_ARCHIVE != '0') ? 'default' : 'no_archive'; $html_msg['EMAIL_SUBJECT'] = EMAIL_PAGE_NOT_FOUND_SUBJECT; $html_msg['EMAIL_MESSAGE_HTML'] .= str_replace('\n','',$email_text); zen_mail('', SEND_404_ERRORS_EMAILS_TO, $email_subject, $email_text, STORE_NAME, EMAIL_FROM, $html_msg, $module); // EOF Send email to admin for 404 errors }

empty query string

Thanks for that.

There is now content in the message body:
the host ip and user ip always show up but the query never.

I have tried different emails, text/html, local-remote hosting, switched off the CEON URI mapping..but the email never shows the page requested.

Re: empty query string

torvista, do you happen to have the SuperGlobals plugin installed? I'm wondering what the information in your store's $_ENV and $_SERVER are for the request-related information.

I'm successfully using the previous version of this plugin on a 1.3.9h store with Ceon URI mapping, so that's not it.

Does it make a difference if you change

Code:

$email_text = sprintf(EMAIL_PAGE_NOT_FOUND_CONTENT, $_SESSION['customers_host_address'], $_SESSION['customers_ip_address'], $_ENV['REQUEST_URI'])."\n\n";

to

Code:

$email_text = sprintf(EMAIL_PAGE_NOT_FOUND_CONTENT, $_SESSION['customers_host_address'], $_SESSION['customers_ip_address'], $_SERVER['REQUEST_URI'])."\n\n";

Re: empty query string

Yes I have Superglobals installed and I have yet to see _ENV even appear in the globals listing.
Using _SERVER as you suggested fixed the problem.

So for curiosity, what is and when should I see _ENV set?

Thanks

Re: empty query string

My _ENV (both XAMMP localhost and 1and1 hosting) show _ENV as pretty much a copy of _SERVER. I'll get that update into the queue.

Re: empty query string

A user at host address [xxx.xxx.76.40] with IP address [xxx.xxx.76.40]
generated a 404 using the query string
[/index.php?main_page=page_not_found].

Getting this message. Cant we get the actual url that led to this page_not_found page.

like if this user type www.mydomain.com/secure and there is no such address on my website , we should get message:

A user at host address [xxx.xxx.76.40] with IP address [xxx.xxx.76.40]
generated a 404 using the query string
[/secure].

Re: empty query string

relish, there are two possibilities:

1. Did you update your store's root .htaccess file to contain

Code:

ErrorDocument 404 /index.php?main_page=page_not_found

2. If you did, then it's possible that the /secure access is generating a 403 (permission error) rather than a 404 (not found) error. You can force the plugin to send emails in this case, too, by updating your .htaccess file to contain the following as well

Code:

ErrorDocument 403 /index.php?main_page=page_not_found

Thanks boss !

Though we have not updated the .htaccess file , we are getting the queries which generate 404 error:

Quote:

A user at host address [pluto.hostonwin.com] with IP address
[206.72.195.228] generated a 404 using the query string
[/index.php?main_page=shippinginfo/extras/ipn_test_return.php].

A user at host address [117.198.89.34] with IP address [117.198.89.34]

[93.158.114.134] generated a 404 using the query string
[/index.php?main_page=products_new/extras/curltest.php].

A user at host address [mail.nap.websolute.com.br] with IP address
[200.150.205.30] generated a 404 using the query string
[/index.php?main_page=shippinginfo/extras/curltest.php].

[200.150.205.30] generated a 404 using the query string
[/index.php?main_page=specials/admin/file_manager.php/login.php].

I think they are hacking attempts , could that be true ?
Our ZC installation is 1.5 and the security guidelines has been followed as per the guide posted on ZC tutorials (http://www.zen-cart.com/wiki/index.p...ecommendations).
Is there anything to worry about? Will be helpful if anybody could elaborate

Thanks

Re: empty query string

relish, what you're seeing are probes from people trying to exploit weaknesses in previous versions of Zen Cart (I've seen the same on various stores) -- you should be fine with v1.5+ and following (as you said) those security guidelines. I usually just let them be, unless they start hogging my bandwidth. If that's the case, I update the top of the .htaccess file in the root of my store to include the additional IP address ... I've filled in two from your query:

Code:

# Block specific IP address ranges order allow,deny deny from 117.198.89.34 deny from 93.158.114.134 allow from all

Re: Generate an e-mail on page-not-found (404) errors [support thread]

While the current version in the plugins will "play nice" with Zen Cart v1.5.5, it needed a change for PHP 7.0 compliance (class constructor named __construct). v1.2.3 has been submitted to the plugins to correct this incompatibility.

Re: Generate an e-mail on page-not-found (404) errors [support thread]

I've just submitted v1.2.4 for the Zen Cart moderators' review and will post back here when it's available for download.

This version contains changes captured for GitHub issue #2. Language constants (and pseudo-configuration definitions) have been moved from the auto_loader to a language-based extra_definitions file.

The email report now includes the contents of the entire $_SERVER and $_SESSION values.
