Adding CAPTCHA protection

There are several PrestaShop modules available that add CAPTCHA support to a site. Some plugins require a fee, while others require registration. One CAPTCHA plugin that is free is SlideCaptcha. Unlike most CAPTCHAs, which require users to enter a series of characters, SlideCaptcha simply requires a user to drag a slider, which unlocks the page:

  4. Click Choose a file, select the slidecaptcha.zip file on your local computer, and then click Open.

You must add this line of code to any forms that you want to protect. For example, to protect the default theme’s contact page form:
  • Open the themes/default-bootstrap/contact-form.tpl in a text editor.
  • Add the line of code to where you want SlideCaptcha to appear. For example, you can insert the code just before the <div class=“submit”> line.
  • Save the changes to the contact-form.tpl file.
  • Use your browser to go to the site’s contact page. You should only be able to submit a message after you move the slider and unlock the form.
