PHP CRUD Tutorial with MySQL & Bootstrap 4 (Create, Read, Update, Delete)

In this PHP CRUD Tutorial we’re going to create a fully functional PHP CRUD application with Bootstrap and MySQL. PHP CRUD stands for Create, Read, Update, Delete which is an easy way to memorize all the components needed for a fully dynamic web site application. We’re going to be using MySQL statements called INSERT, SELECT, UPDATE, and DELETE which correspond to CRUD functionality.

This is a very good tutorial! Thank you Clever Techie!

If you ever encounter that your Delete Message Alert is not display…

Put a die() function right after the header(‘location: index.php’);

It will look like this:
if (isset($_GET[‘delete’])){
$id = $_GET[‘delete’];
$mysqli->query(“DELETE FROM data WHERE id = $id”) or die( $mysqli->error());
$_SESSION[‘message’] = “Record has been deleted!”;
$_SESSION[‘msg_type’] = “danger”;

header(‘location: index.php’);

Great….Made it simple Thanks

TheLewisOSF says:

I followed this tutorial, but I can’t get the Update part to work, when I click the Update button, it routes to my “process.php” page, to a blank screen. I don’t really understand why. My code for this has been copied completely, please help?

Philips Future says:

A.M.T. Sangeeth says:

Nice lesson!!!

Mr.Chanty Sad says:

well done thanks teacher

Steve Carter says:

Great tutorial, thank you for all your super-helpful videos! I am following along step-by-step and have encountered an issue at the ‘Edit’ user section.

You put your ‘SELECT * FROM data WHERE id = $_GET[‘edit’]’ query and variable-setting logic in the process.php file as if it was supposed to be called when the Edit button is clicked. But, the Edit button’s href target is itself, the index.php page. How is the code in process.php to retrieve the selected user’s record being invoked and how are the updated $name and $location variables getting passed back to index.php?

I had to put the query and variable-setting logic in the index.php file above the add/edit form

to get it to work.

I thought I was getting this really well but am really confused now – I don’t understand how your code works since:
1) you aren’t calling the process.php file when you click an ‘Edit’ button,
2) nor are you passing any SESSION or GET variables back to index.php from the Edit code in process.php even if you got there somehow.

I’m sure I’m missing something obvious but I am stumped right now.

ValerieDianhey says:

This helped me out so much!! I was wondering how this could be used if there were multiple tables in the database and not just the data table

Second Wind says:

realy good tutorial simple and to the point, minor criticism could have been useful with a little more explenation 8/10

Shalaw Fatah says:

This is by far the most successful tutorial I’ve watched on PHP, MYSQL. I’d love to see a video on search function in the database, and pagination. Also, it would be good if you could depend on CSS3 instead of Bootstrap. I really appreciate the work. Thanks.

Juan Carlos Ajahuana says:

Nice crud, thanks

Christian Fall says:

so that $row variable is not a part of mysqli methods or other
