Get reCAPTCHA on your ClassiPress Single Ad Contact Form

Tested on WordPress 3.6.1  &  ClassiPress Version: 3.3.1

Did your customers ever complain about email spam comming from your ClassiPress site? Let’s try to make it a bit more difficult for the spammers. In this tutorial we will replace the simple math question under the description with a reCAPTCHA. Of course we don’t touch the core files! We do all our changes in a child theme.

Check the demo site

I assume that you have WordPress Classified Ads Theme and your own child theme running. Time to get started:

Step 1

Create a reCAPTCHA key on the Google reCAPTCHA site. To do so, just enter your domain on that site and let Google create you a key. The result will be this:


Open your ClassiPress admin area, => ClassiPress => Settings => Security (tab) and set the keys in your reCaptcha Settings. Enable reCAPTCHA and save the settings.

Step 2

Now we need to copy a core file and place it in our child theme folder. I’m talking about the /themes/classipress/includes/sidebar-contact.php. Create a /includes folder in your child themes folder (so it looks like this: /themes/your-childtheme/includes/) and upload a copy of that sidebar-contact.php file into that /includes folder. So now you have this: /themes/your-childtheme/includes/sidebar-contact.php

Now open your /themes/your-childtheme/includes/sidebar-contact.php with your editor and find this part of code (around line 13):

Replace the above code with this one:

    may i ask a slight unrelated question please?

    So I have the captcha for the classipress setup in the settings are and now with this mod in the contact sidebar area.

    I have a contact form which I need to download the real simple captcha for but since it is already being used 2 times in my site I figured its already there.

    Can you please direct me how to link my contact form 7 captcha to become functional using the same classipress already built in captcha so I do not add another unecessary plugin to the site?

    Please and thank you samcy

    I have done this tutorial:
    “Redirect your visitors to a THANK YOU page after using the contact form sidebar ClassiPress”

    I modified the functions.php file as requested and it worked (except that now I always say that the calculation of safety is wrong! But I already wrote in the post for this problem).

    Now I have started doing this tutorial.
    In functions.php I pasted the code that was here but at the moment to save the entire screen has turned white.
    Then I tried to delete the code that I put in the functions.php from the tutorial of “Redirect ….” and just to put this new tutorial.
    Result: the sidebar of contact no longer loads.

    Then I put the old code of the first tutorial and the sidebar is loaded but still the calculation of safety does not work.

    I hope to hear from you soon.

    this is the code im getting in the message area:

    Parse error: syntax error, unexpected T_ENDIF in /home/content/31/12093631/html/wp-content/themes/classipress-childtheme/includes/sidebar-contact.php on line 79

    did step by step any thoughts or suggestions?

    I have the same identically problems… with the first mod (redirect after send a msg) work except for the original captcha calculator (i put a wrong result but the msg sent)… for this reason I have buyed this tutorial to make a new captcha sistem but now my sidebar_contact is empty like it dont loaded!

    Any help?

    You are right. This is caused when both modifications are done.

    Please try this when you are using the article for the reCaptcha:

    When you edit the sidebar-contact.php leave the following part at the end away. This one here:

    < ?php endif; ?>

    After you removed that line, save that file.

    Now do not place anything into the functions.php as this is already done by the other modification (redirect users…)

    Continue with step 4 (style.css)

    That should solve the problem.

    My reCaptcha shows only 1 word (instead of 2) :

    Could you tell me what’s wrong?


    • Rolf Hassel June 15, 2014 at 09:36 #

      You can not do anything about that. Google decides if people get asked for one or two words, or numbers. It’s random.
