Thanks for the nice words on the book. It is appreciated. So to confirm, are you still having a problem or no?
Hi,
Actually I have some questions in this topics that are still unanswered.
First:
I have not understood yet, why trim() should be apply for password.
As I understand, trim a string is something like:
$p=" t!=1 "; trim ($p); echo $p; // This line will print "t!=1"
It removes spaces before and after. But as I know we always use spaces to make our password stronger.
And my final question what is the problem with my script that has not worked yet. I have not found syntactical problem but maybe I have logical.
Thank you very much.

Hello Bahaa,
To understand more about some unfamiliar calendars, First of all I introduce them
Two different calendars use as formal calendar in middle-east :
First : Lunar-Calendar(Hijri) - it uses by Muslims and Arabic countries. (As i write this post the lunar calendar is 1432,09,21)
Second: Sun-Calendar(Jalali) - it uses by Persian language countries like Iran, Turkmenistan, Afghanistan and other persian language countries.... (1390,05,31)
And other one is from China:
Third : Chinese Lunar Calendar - it used by Chinese people however maybe a little hard and I do not understand it but this year of Rabbit. (100,07,23)
I found a Gregorian Calender to Lunar Calendar converter is written by Tayeb Habib and source from www.redacacia.wordpress.com, email: tayeb.habib@gmail.com

Hello Zanimation, I put the registrar data into database and modifier file included line below:
Register.php
<div id="content"> <?php $errorys = array(); if (isset($_POST['Submitted'])) { $errors = array(); // put errors into an array // Validate first name if (empty($_POST['first_name'])){ $errors[] = 'Please enter first name'; }else{ $fn = trim($_POST['first_name']); } // Validate Last Name if (empty($_POST['last_name'])){ $errors[] = 'Please enter last name'; }else{ $ln = trim($_POST['last_name']); } // Validate email address if (empty($_POST['email'])){ $errors[] = 'Please fill email address'; }else{ $e = trim($_POST['email']); } // Validate password to enter both verification and main password if (!empty($_POST['password']) && !empty($_POST['verification_password'])){ // Validate that passwords are matched or not if ($_POST['password']==$_POST['verification_password']){ $p = trim($_POST['password']); }else{ $errors[] = 'Passwords are mismatched'; } }else{ $errors[] = 'Passwords has not entered yet'; } if(empty($errors)){ //check for errors //connect to db require_once('includes/db.php'); // make query $q = "INSERT INTO users (first_name, last_name, email, pass, registration_date) VALUES ('$fn', '$ln', '$e', SHA1('$p'), NOW())"; $r = @mysqli_query ($dbc,$q); //run mysql query if ($r) { //if it worked properly echo "Thank you, Mr.$ln, your registration done successfully"; //print success message } else{ //if it did not work properly echo "An unknown error occured please contact admin if this error persist"; //error message } }else{ // if errors occured show errors; foreach($errors as $msg){ echo " - $msg <br/>\n"; } echo '<p>please try again.</p>'; } } ?> <form method="Post" action="register.php"> <br/><br/>First Name: <input type="text" name="first_name" value="<?php if(isset($_POST['first_name'])) {echo $_POST['first_name']; }?>" /> <br/><br/> Last Name: <input type="text" name="last_name" value="<?php if(isset($_POST['last_name'])) {echo $_POST['last_name']; }?>" /> <br/><br/> Email: <input type="text" name="email" size="40" value="<?php if(isset($_POST['email'])) {echo $_POST['email']; }?>" /> <br/><br/> Password: <input type="password" name="password" /> <br/><br/> Verify Password: <input type="password" name="verification_password" /> <br/><br/> <input type="hidden" name="submitted" value="1" /> <input type="submit" value="submit" /> <br/> </form> </div>Change password file ,password.php:

(email) - varchar(60) - NOT NULL
(pass) - char(40) - NOT NULL
(registration_date) - datetime - NOT NULL
At the end I want to thank you very much. and sorry for bad writing models because i am a novice in programming language and i do not know where should i put spaces or comments.

Hi and thank you Zanimation and Stuart.
Finally I could understand what is the problem. There was a wrong with SHA1. I removed the condition of AND in this line:
$q = "SELECT user_id FROM users WHERE (email='$e' AND pass=SHA1('$cp'))";Changed to:
$q = "SELECT user_id FROM users WHERE email='$e'";
I was able to run step 2 successfully. I think I need to trim($cp) and trim($np) to give me the best result.
But i do not understand why trim() should be apply for password.
As I understand, trim a string like:
$p=" t!=1 "; trim ($p); echo $p; // This line will print "t!=1"
It removes spaces before and after. But as I know we always use spaces to make our password stronger.
I will be happy to answer this question too.
Thank you very much

Hello,
My name is Pejman Ghasemi. first of all I want to thanks Mr.Larry Ullman. PHP 6 AND MYSQL5 is the best book I have ever read. I never could understand the example and explanation of other books but this one is easy and useful.
Unfortunately Whole Today I worked on script 8.3 to run it but have not run it yet. so i decided to ask you help me.
require_once('includes/db.php'); $e= "test"; $cp = 'test'; $np = 'pejman'; $q = "SELECT user_id FROM users WHERE (email='$e' AND pass=SHA1('$cp'))"; $r = mysqli_query($dbc,$q); $num = mysqli_num_rows($r); echo 'step1'; if ($num == 1){ //check if there is any email and the password matched echo 'step2'; //Receive user_id data $row = mysqli_fetch_array($r,MYSQLI_NUM); echo $row[0]; //Make update query $q = "UPDATE users SET pass=SHA1('$np') WHERE user_id=$row[0]"; $r = mysqli_query($dbc,$q); if (mysqli_affected_rows($dbc)==1){ //if update ran ok... echo '<h1>Thank you</h1>'; echo '<p>Your password changed.</p>'; }else{ //else of if update ran ok... echo '<h1>Error</h1>'; echo '<p>Sorry we faced an unknown error system Please try again.</p>'; } //end of if update ran ok... }else{ echo 'step3'; }I put echo 'steps' to know which step is work properly. by changing parameters to wrong data i see step 1 and step 3 but i have never seen step 2....
Please help me .
Thank you very much.

Hello Mr.Larry Ullman,
I would appreciate of you. I suggested your books to many of my friends.
I hope you keep writing new books and release them. I know may this ask is not related to the topic but PHP is not Satisfactory to create a web page. because as you said PHP is a server-side programming language. And We can not decorate our website in client-side. So there is another language beside the is called Java Script.
Do you have a good resource that we study javascript.
Regards.
