    Mod_Rewrite Is Not Working With My Urls

    in PHP Advanced and Object-Oriented Programming: Visual QuickPro Guide (3rd Edition)

    Posted

    I am trying to make SEO friendly URLs of using apache mod_rewrite.

    My normal URLs is something like this -

    index.php?p=about
index.php?p=contact
index.php?p=this

    My expecting SEO friendly URLs should be something similar to this -

    localhost/php_advance/ch02/about
localhost/php_advance/ch02/contact
localhost/php_advance/ch02/this

    I tried it with creating a .htaccess file and doing some changes to my apache httpd.conf file.

    This is my .htaccess file

    <ifModule mod_rewrite.c>

# Turn on the engine:
RewriteEngine on

# Set the base to this directory:
RewriteBase /php_advance/ch02/

# Redirect certain paths to index.php:
RewriteRule ^(about|contact|this|that|search)/?$ index.php?p=$1

</ifModule>

    And also, At the end of the httpd.conf file, I added some code like this -

    <Directory "C:/wamp/www/php_advance/ch02">
AllowOverride All
</Directory>

    NOTE: I am using WAMP server and Windows 07

    But this coding is not working for me. Hope someone will help me out. Thank you.

    Form Function Modifing With Radio Button..

    in Effortless E-Commerce with PHP and MySQL

    Posted

    I have modified form_functions.inc.php to radio button for suit for me. But It seems its not working..

     

    This is my code so far..

     

    from form function

     

       	 if (preg_match('/sex\d{1}$/', $name)) {
           $i = substr($name, -1);
           $name = substr($name, 0, 3);
           $sex = array(1=>'Male', 'Female' );

           // Display the error first:
           if (array_key_exists($name, $errors)) {
               echo ' <span class="inline-error">' . $errors[$name] . "</span>\n";
           }

           echo '<input type="' . $type . '"  name="' . $name . '"  value="' . $i . '" /> ' . $sex[$i] . '   ';
       }

     

     

    This is from validation code..

     

        // Check for gender:  
   $sex = array();
   for ($i=1, $count=2; $i <= $count; $i++) {
       if (isset($_POST['sex'. $i])) {
           $sex[] = $_POST['sex'. $i];
       }
   } // end for loop
   if (empty($sex)){
       $reg_errors['sex1'] = 'You have NOT entered your gender type!';
   }

     

    This from HTML

     

                               	 <div class="last-child">
                               <?php
                                 for ($i=1, $count=2; $i <= $count; $i++) {
                                   create_form_input('sex' . $i, 'radio', $reg_errors);
                                 }
                               ?>
                               </div>

     

     

    radio button working.. but validation not working its always going to error message..

     

    hope someone help me out this..

     

    thank you.

    Geting Url Form Users And Validate Them

    in PHP and MySQL for Dynamic Web Sites: Visual QuickPro Guide (4th Edition)

    Posted

    Hello...

     

    I have a form to get some urls from users. Eg: Web Address, Facebook Address, Twitter Address, Google+ address etc... My problem is how I validate these urls when they submit the form. I tried to validate URL in PHP by using the FILTER_VALIDATE_URL or simply, using regular expression.

     

    Here, I would like to know what are the best methods to get such a urls from users. Is it always good to let them to enter protocol? sometimes they may not know it is http, https, ftp, ftps.. etc. I think it is something hard to do some users.

     

    I tried something like this using FILTER_VALIDATE_URL, But it always use protocol and sometime I am confusing how its work..

     

    // validate url
$url = '[url="http://www.example.com%27;"]http://www.example.com';[/url]

if (filter_var( $url, FILTER_VALIDATE_URL)){
echo "<br>valid";
} else {
echo "<br>invalid";
}

[b]OUTPUT[/b] : valid

     

     

    // validate url
$url = 'hp://www.example.com';

if (filter_var( $url, FILTER_VALIDATE_URL)){
echo "<br>valid";
} else {
echo "<br>invalid";
}

[b]OUTPUT[/b] : valid

     

    // validate url
$url = 'http://example.com';

if (filter_var( $url, FILTER_VALIDATE_URL)){
       echo "<br>valid";
} else {
       echo "<br>invalid";
}

[b]OUTPUT[/b]: valid

     

    // validate url
$url = 'http://example.com?id=32&name=kamalani';

if (filter_var( $url, FILTER_VALIDATE_URL)){
       echo "<br>valid";
} else {
       echo "<br>invalid";
}

[b]OUTPUT[/b] : valid

     

    Can you tell me what are the best ways to get urls from user and how those validate?

    Any comments are greatly appreciating..

     

    Thank you.

    How I Create This Dynamically Generated Form.

    in PHP and MySQL for Dynamic Web Sites: Visual QuickPro Guide (4th Edition)

    Posted

    thanks for reply.. SQL return the values properly...there are category_id, category_name, subject_id, subject_name. I have started the session properly in my configuration file and have included to this page. I am trying to display above return data into a list something like this..

     

    Catagory 01
  subjects1   subjects4
  subjects2   subjects5
  subjects3   subjects6

Catagory 02
  subjects1   subjects4
  subjects2   subjects5
  subjects3   subjects6

Catagory 03
  subjects1   subjects4
  subjects2   subjects5
  subjects3   subjects6

     

    I tried to do it like this. Its working as 50%. But I need to display subjects under each categories in a table with 2 columns.

     

        $catID = false;


   while ($row = mysqli_fetch_array($r, MYSQLI_ASSOC)) {

       echo '<div>';

       if ( $catID != $row['ci']) {

           echo '<h3>Category 01: <span>' . $row['cn'] . '</span><span></span></h3>';
       }

       echo '<div class="container">';

           echo '<p>' . $row['sn']. '</p>'; // This subjects I need to display in a table with 2 columns..

       $catID = $row['ci'];

           echo '</div>';

       echo '</div>';
   }

     

    The problem I face is, when I am tring to add the subjects into a table..

     

    This is my HTML design..

     

    <div>
 <h3>Category 01: <span>Information Technology</span><span></span></h3>
 <div class="container">

   <table>
     <tr>
       <td width="50%">
           <input type="checkbox" value="1" name="category[]">Subject1
       </td>
       <td width="50%">
           <input type="checkbox" value="2" name="category[]">Subject4
       </td>
     </tr>                                    
     <tr>
       <td width="50%">
           <input type="checkbox" value="1" name="category[]">Subject2
       </td>
       <td width="50%">
           <input type="checkbox" value="2" name="category[]">Subject5
       </td>
     </tr>                                    
     <tr>
       <td width="50%">
           <input type="checkbox" value="1" name="category[]">Subject3
       </td>
       <td width="50%">
           <input type="checkbox" value="2" name="category[]">Subject6
       </td>
     </tr>

    I am going to create a HTML form dynamically with php. Using that form users can select subjects under different category. A category and Its subjects have broken to one logical section and have applied jquery accordion. In my form I need to create more logical section like that.

    <form action="" method="post">
<div id="accordion">
<!-- logical section 1 -->

<h3>Category 01: <span>category name</span><span></span></h3>
<div class="container">
<table>
<tr>
 <td width="50%">

    How Can I Create This Sql Query?

    in PHP and MySQL for Dynamic Web Sites: Visual QuickPro Guide (4th Edition)

    Posted

    hi.. everyone..

     

    This is a sql query problem that I have uncounted and have been in the same script for hours. But Still I couldn't get it to work.

     

    I need to get a image from database and its type should be one of a value from my $designation array. The query should check $designation array's value with database and if its match with one of a value in database then query can retrieve one row.

     

    This is my designation array. its value I use for image type in my db.

     

    $designation = array ( 'Managing Director', 'Manager', 'Director', 'The Principal', 'Deputy Principal', 'Proprietor', 'Assistant Manager', 'Head Master');

     

    My problem is how can I check these value exit in my table and how can I make a query for this. In query where condition is confusing to me...

     

    any comments are greatly appreciated.

    Thank you..

    Print Database Result From Out Of While Loop

    in PHP and MySQL for Dynamic Web Sites: Visual QuickPro Guide (4th Edition)

    Posted

    hello... everyone..

     

    I have some small problem. It is when Im fetch data from my database and print those in different location.

    I have a database to store images and it contain many type of images. Eg. gallery image, comments image, ad image and so on. So now I need to get only images which type is 'ad'.

     

    Note: A single user can store only 2 images as ad images. That mean there are two ad images to a particular user.

     

    It ok for me. I did it like this.

     

    $q = "SELECT image_name FROM images WHERE image_type = 'ad' AND user = $id";
$r = mysqli_query( $dbc, $q );
while ( $row = mysqli_fetch_array( $r, MYSQLI_ASSOC)) {
 $imageName = $row['image_name'];
 $imageName; // two images contain in this variable.
}

     

    My problem is, can anybody say, is there a way to print those 2 images in different location (in different two DIV ) and out of while loop.

     

    Eg: <div class="add1"> image1 </div>

    <div class="add2"> image2 </div>

     

    any comments are highly appreciated.

    thank you.

    I need to rewrite this URL

    like this

     

    http://www.mydomain.com/profiles/tutors/1255/Kasun+Perera.html

     

    I tried this with Apache’s mod_rewrite feature. But I couldn't reach to my expecting result.

     

    Here is Code that I have tried.

     

    <IfModule mod_rewrite.c>
RewriteEngine on

    Form Input Fuction Is Modifing With Check Boxes And Select Menu

    in Effortless E-Commerce with PHP and MySQL

    Posted

    Hello...everyone...

     

    In my registration form I need to add some check boxes to select more than 1 option about teachers' class option. Larry's Effortless E-Commerce with PHP and MySQL book teach us how to use form input function for text, password and taxtarea inputs. So I modified the function for my check boxes. there I need to display a error message in my registration form when a user not select at least one option from the teacher option check boxes in my register page. further I need to display my error message above the check boxes as Larry did to textarea.

     

    I tried like this in my form function... but I can't get my error message... can anybody tell me where I have gone wrong????

     

    this code is my form function.

     

    } elseif ($type == 'checkbox') {

 if ( $name == 'option[]' ) {
  // Display the error first:
  if (array_key_exists($name, $errors)) echo ' <span class="error">' . $errors[$name] . '</span>';
  // Start creating the textarea:
  echo '<input type="' . $type . '"  name="' . $name . '"  value="1"  class="checkbox" />  Individual<br />';
  echo '<input type="' . $type . '"  name="' . $name . '"  value="2"  class="checkbox" />  Small Groups  <small>( Below 10 )</small><br />';
  echo '<input type="' . $type . '"  name="' . $name . '"  value="3"  class="checkbox" />  Medium Groups  <small>( Between 10 to 20 )</small><br />';
  echo '<input type="' . $type . '"  name="' . $name . '"  value="4"  class="checkbox" />  Big Groups  <small>( Over 20 )</small><br />';
  echo '<input type="' . $type . '"  name="' . $name . '"  value="5"  class="checkbox" />  Online Tuition<br />';
 }
 if ( $name == 'medium[]' ) {
  // Display the error first:
  if (array_key_exists($name, $errors)) echo ' <span class="error">' . $errors[$name] . '</span>';
  // Start creating the textarea:
  echo '<input type="' . $type . '"  name="' . $name . '"  value="1"  class="checkbox" />  Hindi<br />';
  echo '<input type="' . $type . '"  name="' . $name . '"  value="2"  class="checkbox" />  English<br />';
  echo '<input type="' . $type . '"  name="' . $name . '"  value="3"  class="checkbox" />  Tamil<br />';
 }  
}// End of primary IF-ELSE.

     

     

    These are my register.php page

     

    // Check for Institute Options:
if(empty( $_POST['option'])) {
$reg_errors['option'] = 'Please select at least one tuition option';
} else {
 $option = $_POST['option'];
}
// Check for Institute medium:
if(empty( $_POST['medium'])) {
$reg_errors['medium'] = 'Please select at least one tuition medium';
} else {
 $medium = $_POST['medium'];
}

     

     

    This is My HTML part in register page

     

       <div>
	<label for="option">Tutoring Option <img src="../images/required_star.png" alt="required" /> : </label>
	<div class="checkbox1">
	 <?php create_form_input('option[]', 'checkbox', $reg_errors);?>
	</div>
   </div>
   <div>
	<label for="option">Tutoring Medium <img src="../images/required_star.png" alt="required" /> : </label>
	<div class="checkbox1">
	 <?php create_form_input('medium[]', 'checkbox', $reg_errors);?>
	</div>
   </div>

     

     

    any helps are greatly appreciated...
