00:00 | Welcome to the 3rd part of the User Registration tutorial. |
00:04 | In this part, we are going to check for existence of all that was discussed in the last part. |
00:10 | Let us have a quick recap of what was done in the last part. |
00:14 | We have striped the tags off our "fullname" and "username". |
00:19 | We have stripped and encrypted our "password". |
00:23 | Remember this sequence for the functions so that we are not striping off our encrypted value. |
00:30 | Here, we are going to start our registration process. |
00:34 | I'll be checking the existence of all these. |
00:38 | Just before I do that, I am going to set the "$date". |
00:43 | Now, this is using the date() function. |
00:47 | Inside, we have "Y" for the year, "m" for the month and "d" for the date. |
00:55 | It's the capital "Y" for 4-digit year. If we use a small "y", it would be a 2-digit year. |
01:02 | So, in my database, at the moment, I have my year first, then my month and my day and these are separated by hyphens. |
01:15 | You can see this when we enter our database here and insert a value into "users". |
01:22 | We can see that the "date" is in a specific format, if we use this kind of function here. |
01:29 | When I click today, you can see here that we have got the year in a 4-digit format and our month here and our day here, separated by hyphens. |
01:40 | It's adjusted into that structure in my database. |
01:45 | Okay, so if '$submit' then we need to check for existence. |
01:51 | I will add a comment here "check for existence". |
01:55 | Now, this is really easy. |
01:58 | All we want to do is, we have to say "if" statement and a block of code after that. |
02:05 | The condition will be 'if $fullname, $username, $password and $repeat password exist', we have the evidence here.... we will say if $username followed by AND, so double ampersand symbol. |
02:24 | Then we will say "$password" and then we'll say.... |
02:28 | Oh! I forgot the "$fullname" here, so I'll add it there. |
02:33 | Separate these with a double ampersand sign. |
02:38 | The last one is "$repeat password"; so type that. |
02:42 | We are going to require all of these. |
02:46 | Else, we will say - echo "Please fill in" and in bold, "all", "fields!". |
02:57 | We will put a paragraph break after that. |
03:01 | Also, let me put a paragraph break before the form so that we don't need to add it to every error message we give. |
03:10 | So, that's it. Let's just try it. |
03:13 | I will go back to my "Register" page. |
03:17 | We got it here. Let's click in register. |
03:20 | "Please fill in all fields!". |
03:22 | Let's type a couple of fields here. |
03:25 | Let's choose one of our passwords. |
03:27 | We will not repeat our password. |
03:30 | Register. Oh! repeat password.... |
03:42 | '$repeat password'. |
03:45 | The reason this is not working at the moment is, an "md5" value of nothing is equal to an "md5" string of text. |
03:56 | An encrypted string of text. |
04:00 | So, I realize what we need to do is, take out the "md5" function here. |
04:06 | Make sure you remove the end brackets. I will come down here and check for all of our data. |
04:14 | So, let me go back and try this again. |
04:17 | Remember it didn't work before when we didn't chose a "Repeat password". |
04:23 | So, if I didn't chose a repeat or a password we get our error. |
04:30 | If I again choose a value except the "Repeat password", we still get this error. |
04:37 | That's the problem. What we should say is - if everything exists then we can convert our password and repeat password. |
04:46 | So I will just say "$password" is equal to "md5" of "$password". |
04:53 | This will encrypt our original variable value and store a new password code in the same variable. |
05:00 | We also need to say "$repeat password" equals "md5" and "$repeat password". |
05:08 | Here, comment this as "encrypt password". We have encrypted our password. |
05:15 | Now we will go ahead and add all our data into our database. |
05:21 | I am going to do this. Because we have got our data going to our registration, we are going to set a maximum limit for each data that is input. |
05:39 | Now we say 25 characters for our fullname, username, password and repeat password. So the maximum value is 25. |
05:50 | So, I will say- if the string length of '$username' is bigger or greater than 25.... OR |
06:05 | string length of the '$fullname' is greater than 25. |
06:15 | Let us look at these individually and say - if the length of your username or fullname is too long. |
06:24 | Let me put this correctly. |
06:27 | If each of these values is greater than 25 or bigger than 25, |
06:34 | we are going to echo out these values |
06:40 | saying "username" or... no... |
06:48 | Let me say "Max limit for username or fullname are 25 characters". |
06:55 | Otherwise I will proceed to check my password length. |
07:01 | Now I have decided to do this - "check password length" because I want a specific check for this. |
07:12 | "If string length of my password is greater than 25.. or.. string length... |
07:30 | No... um... let's get rid of this, get rid of else. |
07:36 | The first check I want to do is to see if my passwords match. |
07:41 | Let me say "if password equals equals (==)to repeat password" then continue the big block of code. |
07:53 | Otherwise echo out to the user "Your passwords do not match". |
08:00 | Okay? |
08:03 | So, you can type here and we can keep checking your character length. |
08:09 | Now, to check the character length of "username" and "fullname". |
08:14 | So, "check character length of username and fullname". |
08:18 | And that is going to be what we said before, if "username is greater than 25", |
08:25 | rather if the string length used in this function is greater than 25... |
08:31 | OR the string length of fullname is greater than 25, then we echo "Length of username or fullname is too long!". |
08:43 | So, just to keep it simple and then otherwise we will say |
08:51 | "check password length". |
08:57 | Here, I am going to specify or say if... now remember our passwords match... |
09:04 | So we only need to check this on one of the password variables. |
09:09 | Here, I will say - if the string length of the password is greater than 25 or string length of our password is lesser than 6 characters.... |
09:23 | ...then we will echo out an error saying "Password must be between 6 and 25 characters". |
09:35 | This will work for sure. |
09:37 | We will continue this discussion in the next tutorial. |
09:41 | Before that, let me just conclude this with an else statement. |
09:46 | So, otherwise we will say "register the user". |
09:51 | Our code to register the user will go here. |
09:56 | In the next tutorial, we'll test this out and will learn how to register the user and we will put our code here in that tutorial. |
10:06 | This is basically for checking a minimum or maximum limit on our password and this block of code here will be our magical "register the user" piece of code. |
10:17 | So join me in the next part. Bye-bye. This is Mad Madhur, dubbing for the Spoken Tutorial project. |
