CRUD Operation On A User Profile In PHP/ MySQL

Introduction

In this article, I’ll show you how to perform the CRUD operation on a user profile in PHP/MySQL, such as - insert, update, delete, retrieve. This application will work for admins where the admin can add member’s information like username, profile picture, and description etc., i the same way as insertion admin can update member information and also can delete members where only admin can delete member record.

The purpose or aim of this application is to create and manage the work of the user easily by identifying each and every person. This application is created with Bootstrap, PHP/MySQL.

How to create a database in MySQL?

For creating a database, you should follow some steps as given below.

We will create two tables - one for admin and another one for users.

  1. CREATE TABLE `admin` (  
  2.   `id` int(11) NOT NULL,  
  3.   `username` varchar(25) NOT NULL,  
  4.   `password` varchar(25) NOT NULL  
  5. ) ENGINE=InnoDB DEFAULT CHARSET=latin1;  
  6.   
  7.   
  8. CREATE TABLE `users` (  
  9.   `userid` int(11) NOT NULL,  
  10.   `username` varchar(20) NOT NULL,  
  11.   `description` varchar(50) NOT NULL,  
  12.   `userprofile` varchar(200) NOT NULL  
  13. ) ENGINE=MyISAM DEFAULT CHARSET=latin1;  
  14.   
  15.   
  16.    
  17.   
  18. -- Table structure for table `admin`  
  19. --  
  20.   
  21. CREATE TABLE `admin` (  
  22.   `id` int(11) NOT NULL,  
  23.   `username` varchar(25) NOT NULL,  
  24.   `password` varchar(25) NOT NULL  
  25. ) ENGINE=InnoDB DEFAULT CHARSET=latin1;  
  26.   
  27. --  
  28. -- Dumping data for table `admin`  
  29. --  
  30.   
  31. INSERT INTO `admin` (`id`, `username`, `password`) VALUES  
  32. (1, 'admin', 'admin');  
  33.   
  34. -- --------------------------------------------------------  
  35.   
  36. --  
  37. -- Table structure for table `users`  
  38. --  
  39.   
  40. CREATE TABLE `users` (  
  41.   `userid` int(11) NOT NULL,  
  42.   `username` varchar(20) NOT NULL,  
  43.   `description` varchar(50) NOT NULL,  
  44.   `userprofile` varchar(200) NOT NULL  
  45. ) ENGINE=MyISAM DEFAULT CHARSET=latin1;  
  46.   
  47. --  
  48. -- Dumping data for table `users`  
  49. --  
  50.   
  51. INSERT INTO `users` (`userid`, `username`, `description`, `userprofile`) VALUES  
  52. (52, 'Dave Doe', 'Member3', '384680.png'),  
  53. (53, 'March Doe', 'Member4', '930734.png'),  
  54. (44, 'John Doe', 'Member1', '871406.png'),  
  55. (51, 'Jean Doe', 'Member2', '48895.png');

Now, we will start our PHP code.

  10. if($stmt->rowCount() > 0)  
  11. {  
  12.     while($row=$stmt->fetch(PDO::FETCH_ASSOC))

  38. }  
  39. ?>  
  40. </div>  
  41. </div>
