| 00:00 | Welcome to the Spoken Tutorial on POST variable. Here I am going to use the same code as that of the get.php page, the same one that I have done in my GET variable tutorial. |
| 00:13 | If you have not seen that already, please do so and then go through this tutorial. You will be able to know all these codes about. |
| 00:21 | If you already know these codes about and you have not seen the GET tutorial, you are welcome to join us. |
| 00:28 | I have got my page with my get as previous. |
| 00:31 | I have got a new file called 'post.php' |
| 00:36 | Actually, what I want to do is change this as POST and post it as a post variable. |
| 00:44 | So, quite simply and logically I will just go through this and change this to POST |
| 00:51 | and here is what we call 'POST' instead of 'GET' and this will work. |
| 00:57 | Let me show you my post page. |
| 01:00 | There is nothing here. There is no question mark. |
| 01:04 | Let me type "Alex" and click here. But nothing has come up. |
| 01:09 | That is why, |
| 01:11 | do you remember if you are working with another file, you need to change the action. |
| 01:19 | Let's refresh it. |
| 01:22 | I can see "Alex". Let me click here and this is "Hello, Alex". |
| 01:28 | Next, we are in the 'post.php' font and there is no question mark. |
| 01:33 | Something has been taken across. It has been stored inside a post variable. |
| 01:39 | But why it is not showing two users? |
| 01:44 | This will be absolutely brilliant if we can say 'password'. Let's call this 'password'. |
| 02:02 | I'll say here "Thanks for your password" and let's go back. |
| 02:11 | And now, as you can see, this is a password field; |
| 02:15 | so I'll type 123 as my password and I click here. |
| 02:22 | It says, "Thanks for your password". |
| 02:25 | It has been stored. so it can be used. I can use it, if I want to. |
| 02:31 | I'll just change that; so it makes more sense. |
| 02:37 | Let's do a refresh and resend the data. |
| 02:42 | 123, click here and it's not displaying. That's why |
| 02:49 | you should check these things. It is easy to make mistakes. |
| 02:54 | Let me type 123. Let me click here and it says "Thanks for your password" and it has given me my password. |
| 03:06 | It proves that it has been carried across, it has been stored in a post variable. |
| 03:12 | But it hasn't shown the user which could have made sense |
| 03:16 | because there would be no point having these as blocks. They are not readable in any way. |
| 03:22 | And here, there would no point having it because people can read our password. |
| 03:27 | So, it will be very easy for people to look through your internet history |
| 03:32 | and see you have typed your password. But people might get access to your account with that. |
| 03:38 | So you can see this post. These are used for functions, also the amount that can be sent through it. |
| 03:45 | So, if for example, my password was really long say over 100 characters, it will still be accepted |
| 03:52 | but in the 'get' variable you have a hundred character limit. |
| 03:57 | So, the post thus seems to be useful. But if you are evaluating things, like trying to sort out some things, you can use the get variable |
| 04:08 | just to see if your data is being passed through. |
| 04:11 | So basically that's post variable. |
| 04:14 | You would be using it a lot on projects for form submissions. This brings us to the end of this tutorial |
| 04:22 | This is Siddarth for the Spoken Tutorial Project. Thanks for watching. |
