What does Captcha mean? The word CAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart. It means that CAPTCHA helps to understand who the user actually is – a real person or a robot. <\/span><\/p>\n How can this program define it? – Very simple. People are able to see the difference between numbers, letters, and other symbols. So, CAPTCHA can do some manipulations with these signs to check if a user is able to determine them.<\/span><\/p>\n A robot can’t solve this problem, and the program is very useful to prevent scammers and essential to protect personal or website data. So, CAPTCHA provides Internet safety and allows users to feel protected and secure when using different websites.<\/span><\/p>\n Let’s find out CAPTCHA functions and how it operates.<\/span><\/p>\n How does this program perform? What are its functions? <\/span>The main purpose of CAPTCHA is to block spam software from posting comments on pages or buying too many products at once. <\/span><\/p>\n What are the most typical forms of Captcha?<\/span><\/p>\n E-commerce websites usually use CAPTCHA to strengthen security around the most sensitive account access points.<\/span><\/p>\n Let’s consider the most typical ones:<\/p>\n If your online shop is unprotected, you may have serious problems. For example, your customer and email databases will be full of spam email addresses. You will need a lot of time and money to improve the situation.<\/p>\n Take your online store to the next level with BelVG Magento migration<\/p>Visit the page<\/span><\/a><\/div><\/div><\/div>\n If you decide to use a CAPTCHA code, you should take several measures.<\/p>\n Nowadays, there are many cyber attacks, and the Internet can not always be safe and secure for people. Hackers have a great number of scamming tactics, and it is easy for them to trick Internet users. Cybercriminals started integrating CAPTCHA into their fake websites to make their scams more trustworthy.<\/p>\n Is Captcha able to block scammers? What are its most beneficial functions? Does it really provide Internet safety?<\/p>\n CAPTCHA protects:<\/p>\n Moreover, CAPTCHA prevents dictionary attacks and comment spam on blogs.<\/p>\n We can see that there are a lot of helpful and useful functions that can help improve Internet safety and protect from cybercriminals.<\/p>\n Take your online store to the next level with BelVG Magento development<\/p>Visit the page<\/span><\/a><\/div><\/div><\/div>\n Let’s consider CAPTCHA benefits for online businesses and why it should be used on websites. To understand if it is helpful for creating Internet safety, we will describe the main advantages and disadvantages.<\/p>\n Benefits of Captcha for an online store:<\/p>\n Challenges of Captcha:<\/p>\n So, we can see that CAPTCHA advantages outweigh the disadvantages. However, some online stores don’t use it because they don’t want to lose customers who can be frustrated by CAPTCHA.<\/p>\n Step #1<\/strong>: Log in to the Magento admin panel and navigate to Stores -> Settings.<\/span><\/p>\n Step #2<\/strong>: Select the store view you wish to configure CAPTCHA for.<\/span><\/p>\n Step #3<\/strong>: Expand the Advanced tab, select the Admin section, and expand the Captcha section.<\/span><\/p>\n Step #4<\/strong>: Set up the fields as follows:<\/p>\n Step #5<\/strong>: Press the Save Config button.<\/p>\n Step #1<\/strong>: Navigate to Stores -> Configuration.<\/p>\n Step #2<\/strong>: Expand the Customers tab and select Customer Configuration.<\/p>\n Step #3<\/strong>: expand the Captcha section and select Create user in the Forms field.<\/p>\n Step #4<\/strong>: Press the Save Config button.<\/p>\n There is no built-in functionality in Magento for adding a Captcha to the custom form. Therefore, we decided to approach this task creatively and decided to create a specialized module for this purpose. In this paragraph, we will describe how our custom module – Belvg_CaptchaForm – was created and how it functions.<\/p>\n Step #1<\/strong>: Create the following config.xml in the etc folder of the module directory:<\/p>\n Step #2<\/strong>: Define the form ID and its name in order to be able to activate it in the back office.<\/p>\n In our case, the form ID is captcha_form_1 and the form name is Custom Captcha Sample.<\/p>\n Now, if we navigate to Admin > Stores > Configuration > Customers > Customer Configuration > CAPTCHA, we will see our custom form in the Forms field.<\/p>\n Step #3<\/strong>: For convenience, let us make the Captcha open in a new window with the URL address \/captchaForm:<\/p>\n In the module folder, create a view\/frontend\/layout subfolder. In the newly created subfolder, create captchaform_index_index.xml file with the following contents:<\/p>\n Step #4<\/strong>: Create a controller to make a form available at \/captchaForm URL.<\/p>\n In the module folder, create a Controller\/Index directory and place there the following Index.php:<\/p>\n Step #5<\/strong>: Create a class for the Belvg\\CaptchaForm\\Block\\CaptchaForm form block.<\/p>\n In the module folder Block, create a CaptchaForm.php file with the following contents:<\/p>\n Step #6<\/strong>: Create a phtml template for our form in the view\/frontend\/templates folder with the captcha_form.phtml name:<\/span><\/p>\n Now, as we follow the \/captchaForm URL, we will get to our Captcha form page.<\/span><\/p>\n Step #7<\/strong>: Create an action for form processing and make it pass validation: <\/span><\/p>\n In the etc folder, create an events.xml with the following contents:<\/span><\/p>\n Also, in the Observer folder, create the following CheckCaptchaFormObserver.php:<\/span> Step #8<\/strong>: Create a CaptchaFormPost action for form processing in the Controller\/Index folder: And we are finished! Now, as we visit the \/captchaForm link, we will see out custom form with a Captcha. <\/span><\/p>\n <\/p>\n Using the methods described above, it is possible to add Captcha to any form.<\/span><\/p>\n In case the Captcha is not displaying after it was activated in the admin panel, here are three methods you can use to fix it:<\/p>\n Solution #1:<\/strong> Flush the cache by executing the cache:clean command and checking if the captcha block is enabled in CSS.<\/p>\n Solution #2:<\/strong> Check the Captcha’s Displaying Mode configuration in the admin panel.<\/p>\n Solution #3:<\/strong> Check the layout, in particular, whether there is a remove=”true” near the form.additional.info container or the captcha attribute. In case the not displaying Captcha is located at the checkout page, make sure that the captcha element does not have the following config:<\/p>\n If you do not have time to configure Captcha, either programmatically or via the back office, or simply do not wish to allocate your efforts to this aspect, but still want Magento Captcha enabled in your online store, there is a way out for you. Magento Marketplace offers a wide selection of free and paid extensions that provide for any need, and Captcha is not an exception.<\/span><\/p>\n Below you will find a comprehensive selection of 5 best Magento 2 Captcha extensions.<\/span><\/p>\n <\/p>\n <\/p>\n
