PHP PDO CRUD Tutorial using OOP with Bootstrap

By
In this tutorial we will see that how to create database CRUD operations using Object Oriented concept in PDO with Bootstrap framework, i have used here Bootstrap framework for front-end design and the MySQL database operations will done by PDO and OOP, recently i have posted pagination tutorial using PDO and OOP and one of my blog reader request me to post that how to use OOP concept to create CRUD operations in PDO, so in this tutorial i I'm going to explain OOP with PDO using Bootstrap framework. so Learn PHP OOP with PDO.
PHP PDO CRUD tutorial using OOP with Bootstrap
 

Database Design & table

create database named 'dbpdo' and import the following code in your phpmyadmin it will create table and user fields.

CREATE TABLE IF NOT EXISTS `tbl_users` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `first_name` varchar(25) NOT NULL,
  `last_name` varchar(25) NOT NULL,
  `email_id` varchar(50) NOT NULL,
  `contact_no` bigint(10) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=21 ;

edit-data.php
footer.php
header.php
index.php

dbconfig.php

Set the credentials for the database and make a new PDO connection if the connection fails display the error . Next include the ‘class.crud.php’ file and make an instance of it, pass in the database object to the class to make use of the database.

<?php

$DB_host = "localhost";
$DB_user = "root";
$DB_pass = "";
$DB_name = "dbpdo";


try
{
 $DB_con = new PDO("mysql:host={$DB_host};dbname={$DB_name}",$DB_user,$DB_pass);
 $DB_con->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $e)
{
 echo $e->getMessage();
}

include_once 'class.crud.php';

$crud = new crud($DB_con);

?>

class.crud.php

this is the main class file which contains code for database operations.
create() and update() functions are in try/catch block to handle exceptions.
dataview() function selects the whole records from database table.
paging() function set’s the QueryString like “page_no=number”.
paginglink() function creates the paging number links with “previoue and next” feature.
all the CRUD and Pagination operations are done by this file.
<?php

  $this->db = $DB_con;

layouts

To reduce and make it less our code, we will create these two template files: header.php, footer.php
header.php
This header.php file will be included at the beginning of all files so that we won’t have to write the same header codes every-time. this file contains bootstrap file links.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

        </div>
 
    </div>
</div>

footer.php
This footer.php file will be included at the end of all files so that we won’t have to write the same footer codes every-time.

<div class="container">
 <div class="alert alert-info">
    <strong>tutorial !</strong> <a href="http://www.codingcage.com/">Coding Cage</a>!
 </div>
</div>
<script src="bootstrap/js/bootstrap.min.js"></script>
</body>
</html>

index.php

this file will show the records from the mysql database with pagination feature. the table which are used in this file are created under bootstrap data table with class='table table-bordered table-responsive' it will make tables look pretty.

<?php
include_once 'dbconfig.php';
?>
<?php include_once 'header.php'; ?>

<div class="clearfix"></div>

<div class="container">
<a href="add-data.php" class="btn btn-large btn-info"><i class="glyphicon glyphicon-plus"></i> &nbsp; Add Records</a>
</div>

<div class="clearfix"></div><br />

<div class="container">
     <table class='table table-bordered table-responsive'>
     <tr>
     <th>#</th>
     <th>First Name</th>
     <th>Last Name</th>
     <th>E - mail ID</th>
     <th>Contact No</th>
     <th colspan="2" align="center">Actions</th>
     </tr>
     <?php
  $query = "SELECT * FROM tbl_users";       
  $records_per_page=3;
  $newquery = $crud->paging($query,$records_per_page);
  $crud->dataview($newquery);
  ?>
    <tr>
        <td colspan="7" align="center">
    <div class="pagination-wrap">
            <?php $crud->paginglink($query,$records_per_page); ?>
         </div>
        </td>
    </tr>
 
</table>
   
       
</div>

<?php include_once 'footer.php'; ?>

above code will give following output :

Data view Using PDO and OOP


add-data.php

now create a file and name it 'add-data.php' to get data from users to store into mysql database.
in this file some appropriate message are given about data are insert or not with bootstrap label.

<?php
include_once 'dbconfig.php';
if(isset($_POST['btn-save']))
{
 $fname = $_POST['first_name'];
 $lname = $_POST['last_name'];
 $email = $_POST['email_id'];
 $contact = $_POST['contact_no'];
 
 if($crud->create($fname,$lname,$email,$contact))
 {
  header("Location: add-data.php?inserted");
 }
 else
 {
  header("Location: add-data.php?failure");
 }
}
?>
<?php include_once 'header.php'; ?>
<div class="clearfix"></div>

<?php
if(isset($_GET['inserted']))
{
 ?>
    <div class="container">
 <div class="alert alert-info">
    <strong>WOW!</strong> Record was inserted successfully <a href="index.php">HOME</a>!
 </div>
 </div>
    <?php
}
else if(isset($_GET['failure']))
{
 ?>
    <div class="container">
 <div class="alert alert-warning">
    <strong>SORRY!</strong> ERROR while inserting record !
 </div>
 </div>
    <?php
}
?>

<div class="clearfix"></div><br />

<div class="container">

  
  <form method='post'>
 
    <table class='table table-bordered'>
 
        <tr>
            <td>First Name</td>
            <td><input type='text' name='first_name' class='form-control' required></td>
        </tr>
 
        <tr>
            <td>Last Name</td>
            <td><input type='text' name='last_name' class='form-control' required></td>
        </tr>
 
        <tr>
            <td>Your E-mail ID</td>
            <td><input type='text' name='email_id' class='form-control' required></td>
        </tr>
 
        <tr>
            <td>Contact No</td>
            <td><input type='text' name='contact_no' class='form-control' required></td>

        </tr>
 
    </table>
</form>
     
     
</div>

<?php include_once 'footer.php'; ?>


this will create following form :

Insert Records Form using PDO OOP


edit-data.php

after creating a data insert form, this file updates the users data and the update operation are done by update() function which are define in 'class.crud.php' class file

<?php

 }
 else
 {

    <strong>SORRY!</strong> ERROR while updating record !
    </div>";
 }
}

if(isset($_GET['edit_id']))
{
 $id = $_GET['edit_id'];
 extract($crud->getID($id)); 
}

?>
<?php include_once 'header.php'; ?>

<div class="clearfix"></div>

    </table>
</form>
     
     
</div>

<?php include_once 'footer.php'; ?>


delete.php

this file contains code for data delete operation using delete() function by passing id argument's value of selected data and row and by pressing the delete button the record will be deleted and message will be given that the record was deleted.

  2. Very good stuff. Thanks a lot.

  3. very nice script, with all, so use PDO for PHP and use bind of variables style JAVA prepared statements.
    Thank you so much...

  4. Change contact_no in MySQL from int to bigint, and everything starts working.

  5. Gracias por el código.

  6. Nice script! Although, if you keep ?inserted at the end of url and hit submit without a field you get blank in db.. I would put ... if (empty($_POST['example'] || etc, etc)) { header("Location: index.php?failure"); } else { $example = $_POST['example']}inside the if(isset($_POST['btn-save'])) to prevent this.

    ReplyDelete
  7. It is nice to work with, but not safe so, because you can fill out all input fields in the what ever you want, such as, for example, niek# hotmail.com or j@ntje@hotmail.com

    ReplyDelete
  8. I have those other links below once viewed and tried out.
    But when I put a patern as below in the input field then put that doesn't work in this PDO script

    input type='text' pattern="[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4}$" name='email_id' class='form-control' required

    1. try the following, it works

      <input type='email' pattern="[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4}$" name='email_id' class='form-control' required>

      Delete
  9. Thanks that works.
    Only one more question: why email_id and email.
    I ask that because I already have a registration script, with a user_id, user_name, user_email and user_password, But that has no edit and delette script.
    And that's why I use now this Grud script

    ReplyDelete
    Replies
    1. you can change "email_id" into "user_email" and
      <input type="email" />
      well it's a new HTML5 attribute

      Delete
  10. could not find driver

    1. open "php.ini" file of your localhost server and
      find for ";extension=php_pdo_mysql.dll" and remove the
      semi-colon then save file and restart your server it enables PDO Driver.

  11. Great beginning php tutorials Very clear and helpful for beginners.

  12. Thank you for this tutorial. For someone that has to re-learn PHP as several functions (like mysql_connect) no longer work in the newest version of PHP, this has helped me quite a bit. I do have a couple questions though. When adding a phone number in U.S. format (XXX-XXX-XXXX), only the first 3 numbers are added to the database but the first dash and everything behind it is not added. I've been trying to figure out why, but I'm kind of stumped. Any ideas? Also any tips on adding a search function?

    ReplyDelete
  13. Ahh, I figured out why the phone number wasn't doing the dashes. Changed the MySQL table BIGINT to VARCHAR and it saves correctly now.

    ReplyDelete
  14. Nice blog...Very useful information is providing by ur blog. Great beginning php tutorials Very clear and helpful for beginners.

  15. Hi, I posted a comment in your tutorial Simple PHP CRUD Operations.I think i should have posted it here instead. My question is, how do i add images and pdf's to the crud operations. I want the user to upload images and pdf's and save them in folders.

    1. combining these two things is easy, just alter your mysql table and add image, pdf file fields to the table and make change in sql insert query as i showed in following tutorial :

    2. it is easy up to the point where the folder comes in.I am confused as to how and where some of the code from the file upload tutorial will fit into the php-pdo-crud-tutorial. This is what i have so far. Thank you. I really appreciate your help.


      create($first_name,$last_name,$gender, $student_phone_number, $parent_phone_number, $student_email, $course, $admission_type, $qualification))
      {
      $sql="INSERT INTO students(file,type,size) VALUES('$final_file','$file_type','$new_size')";
      mysql_query($sql);
      header("Location: add-data.php?inserted");
      }
      else

      // header("Location: add-data.php?failure");

  18. Hello everybody !

    Thank you very much for this job very well explained, being a novice in php coding, I have a comment,

    Pagination displays all the page numbers, it is a big disadvantage when we have a database with 1000 line,

    Because with 1000 lines in database, if we want to see 10 lines per page, there will be 100 pages number in the paging bar,

    Can we add some settings in the paging function to limit the number of links (number of pages) displayable in the pagination bar?

    Best regards.

    1. did you mean page no as query string in address bar if so , then we can use jquery ,ajax to paginate all the records ...

      Delete
    2. Hi Pradeep !

      In my case I have for example 1000 records (rows) in the database
      The only config parameter for the function is : "$records_per_page=X;"
      With "$records_per_page=10;" there will be 100 page links in the paging bar, it's a lot
      I asked i you cas improve the function by limiting the number of page links displayed

      Cordially, Hafid.

    1. hello taj,

      bindparam(":fname",$fname);

      1 bindParam — Binds a parameter to the specified variable name
      2 colon -- specifies the column which are declared in bindParam(),

      well you can also use this

      bindParam('val', $value, PDO::PARAM_STR);

  43. Hallo admin ..

    previously thank you for sharing script free PDO. This is very cool.

    I added in the database UNIQUE USERS hopes that could not make anything duplicate with others.

    For example, I edit the username as 'Admin' which have previously been stored in the database with another account.

    In fact, USERS can not change their name to Admin, however, ERROR messages that appear unsightly.
    Like this:

    SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'Admin' for key 'uname'

    How to change the error message?

  44. Interesting example, but based on the date of the post,I am surprised that you show it using mySql database connections and not PDO when mySql has been deprecated for several years. At the very least the database connections should be in mySqli. Also as a DB programmer, I would always try to use '?' for params in your query strings for safety/security reasons.
    Do you have updated code for this example?

    1. hi there, why are you surprised, i have just used here PDO extension to Perform CRUD operations with OOP way, and my friend mysql query(extension) is deprecated from several years the PDO extension is improved mysql extension it is a database layer and it also prevent sql injections cause there are prepare, bindparam and execute statements and methods.

    Replies
    1. So long as you have the database in the structure shown and the PDO connector for MSAccess, if there is one, you should be good to go. That's the beauty of PDO; change the database and connector; the rest stays the same. Access previously used MickeySoft connectors RDO and ADO...much similar.
      Amazed to hear someone still using Access.
