PHP Tutorial For Beginners: Google reCAPTCHA v2

at the end of this video tutorial you will know how to protect your forms by using Google recaptcha so stay with me So now I'm here at my PHPstorm and I have created a new product I have also created one empty index.php file and I have started my localhost so if you didn't start your own please do it also first thing that you need to do in order to protect your forms is to create that fork and after that we will I will show you how to protect so I will just create a normal HTML document I will create just one input the type will be text and the placeholder will be What is your name, this is just as an example pain we are going to have one submit button so the first thing that we need to do to implement recaptcha is to go to the google.com slash recaptcha and after that we need to go to click on the get reCAPTCHA you shall not forward you wanna do please do it and now you will have the list of all your recapture sites that you have been using and since this is my test account I don't have any I just have two that I don't use it at all so first thing is we need to create some label this is just for you to remember where is your which site for example for this one I will say a local host tutorial I will to recaptcha V2 and here I need to input the list of the domains where I will use this reCAPTCHA so at the moment I will just use localhost I will click on the accept reCAPTCHA Terms of Service and I don't want any error and I will press on register after that they will create for us some site key secret key etc so the first thing that we need to do inside the HTML is we need to copy this code and paste it just do before the closing body tag the next thing that we need to do is we need to copy this code and paste it just before the closing form tag like this and after that all we need to do is to write the code that will be on the server and that will verify the CAPTCHA so I will say PHP and I will say this is name of this button is submit and I will write one if statement where I will test if someone press this save button and if he is I will just accept all the informations from the form so I have forget here name let's say username so it will help username equal post username we will have secret key from here so our civics key is right here so I will make sure to copy everything sow secret key equal okay the next thing that you need is response so the value of our response is this we need to copy this and we will say response key equal post this and it is optional to provide remote IP but I'm going to show how to get user IP we can get it back from the server remote address and that's it and now the next thing that we need to do is we will just send to the Google secret key response key and the user IP and on the Google they will verify if someone is human actually and they will return those informations to the our so URL we will send those information is here that's why by Google we does need to copy and we will does append secret key resposne key and user IP to get method so we'll say secret equal secret key then we have resposne and removed IP so response equal response key and remote IP equal user IP and that not will cow call the function file get content and we will just provide the URL to that function we could also write this part here to here but I just don't want to complicate things and now let's see what will get us our response so if we refresh you can see that we have got one new HTML form that we have created and also we have got the CAPTCHA from the google so if the implant inside any data here and press save as you can see the goal will say success false which means that our user didn't click on this button and if we try to click wait for them to verify and click on the save as you can see we have got success true which means the user is not robot and it's human so as you can see here the data is the JSON object and we need to convert to the coded data so I will say like this to response let's say again equal JSON decode and now we will have it as an object and we can say if response success echo else echo verification failed and now let's test again so I'll say Senaid I get save verification failed and now if I try again and hit I'm not a robot he'd say it is verification success your name is Senaid so that is extremely easy with us need to do some copy and paste and if you guys have any questions please let in the comments below and also if you like this video please like it and share with your friends Take care
