I am using the charset =utf8
and the question mark returns once at the end of some posts not on all of them.
The issue could be , returning the beginning letters of a word which is in set(30).
-
There is a small issue with this, it returns a symbol as you can see
� at the end.
How can I remove
� the question mark at the end?
Thank you.

I am working on chapter 18 and trying to show some pages in the header if the user is admin but it does not show the link for admin.
It just shows links for registered users but not for admin.
The code is below:
<?php
// Display links based upon the login status:
if(isset($_SESSION['user_id'])) {
echo ' <li> <a href="logout.php" title="Logout">Logout</a> </li>
<li> <a href="change_password.php" title="Change your password"> Change Password</a> </li>';
// Show links if the user is admin:
if($_SESSION['user_id'] == 1) {
echo ' <li> <a href="view_users.php" title="View all the users"> View Users </a> </li>
<li> <a href="#" title=" admin page"> admin page</a> </li>';
}
} else { // Not logged in.
echo ' <li> <a href="register.php" title="Register for the site"> Register</a> </li>
<li> <a href="login.php" title="Login"> Login </a> </li>
<li> <a href="forgot_password.php" title="Reset password"> Reset Password </a> </li>';
}
?>
How can I show the links for the admin?
Note: the admin has got user_level of 1.
Thank you.

Thank you for helping me.

Now I am using the filter_var() to validate name as you can see below.
// Validate name:
if(filter_var( $trimmed['name'], FILTER_SANITIZE_STRING)) {
$p_name = mysqli_real_escape_string($dbc , $trimmed['name'] );
} else {
echo '<p class="error"> Please enter your name. </p>';
}
Is that right?
Thank you
-
This is the code which I have defined the $trimmed array:
// Trim all the incoming data:
$trimmed = array_map('trim', $_POST);
Thank you
-
I mean when I use this RegExp '/^[A-Z \'.-]{2, 40}$/i' then I enter a name, it does not accept the entered name.
Therefore it prints the error message: echo '<p class="error"> Please enter your name. </p>.
Thank you

Chapter 18 - registration form.
I am working on chapter 18 registration form when I validate the name with reg exp it does not accept the input value and reset works fine.
php code:
// Validate name:
if(preg_match( '/^[A-Z \'.-]{2, 40}$/i' , $trimmed['name'])) {
$p_name = mysqli_real_escape_string($dbc , $trimmed['name'] );
} else {
echo '<p class="error"> Please enter your name. </p>';
}
html code:
<label for="name" > Name: </label>
<input type="text" id="name" name="name" size="30" maxlength="40"
value="<?php if(isset($trimmed['name'])) echo $trimmed['name'] ; ?>" />
How can I solve this issue?

I am not using index.php?page=index?
I am trying to use the method that I have showed you.
I use static links but want to use a dynamic method.
Thank you

<nav>
<ul>
<?php
$pages = array(
'Home Page' => 'index.php',
'Register' => 'register.php'
);
$this_page = basename($_SERVER['PHP_SELF']);
foreach($pages as $k => $v) {
echo '<li';
if($this_page == $k) {
echo ' class="current"';
echo ' > <a href="'.$v.'"> <span> ' . $k . ' </span> </a> </li> ';
}
}// End of foreach loop
?>
</ul>
</nav>

Even I have tried to upload a file to a live server but it is not working.
display_errors error is already on.
That is really strange !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
====================================================================
; http://php.net/display-errors
display_errors = On
====================================================================
; The display of errors which occur during PHP's startup sequence are handled
; separately from display_errors. PHP's default behavior is to suppress those
; errors from clients. Turning the display of startup errors on can be useful in
; debugging configuration problems. But, it's strongly recommended that you
; leave this setting off on production servers.
; Default Value: Off
; Development Value: On
; Production Value: Off
; http://php.net/display-startup-errors
display_startup_errors = On
-
It does not show errors or print anything!!!!!!!!!!!!!!!!

I am using windows 7.
uploads folder is inside htdoc and the web root folder inside htdoc.

I am using charset utf8 for database connection, sql database, mysqli table of content and html but the question mark shows at the end of some posts and it returns one question mark only the reset of the text is fine.
Some of the output:
