Now let’s create the form to edit this particular book. $conn = mysqli_connect("localhost","root","","library") Įcho "Error: Unable to connect to MySql" Īnd the Query: $query ="select * from books where book_id =".$book_id Įxecute the query: $result = mysqli_query($conn, $query) To edit or delete a specific book, you have to give an id of that book through GET. This will create a new row in table for each record of the database.Īs you see above, there are two links that lead to the ‘Edit’ and ‘Delete’ pages. while($row = mysqli_fetch_array($result)) After doing that open MAMP and start the Apache web server. Create your project folder inside this htdocs folder. To retrieve values use $query="select * from books" Īfter the execution of the query, use a while loop to go through all the records row by row. Go to the drive on your computer where your have MAMP or XAMPP installed, open up the XAMPP or MAMP application folder, inside this folder you'd find an htdocs folder. To keep the code simple, I haven’t use pagination here and this would cause all records to be displayed on a single page. The page above contains the code that simply retrieves the values from the table ‘books’ using simple “select * from table_name” query. The following code block will create the form above.

Select auto_increment and primary key will create this field. It will act as a primary key and will uniquely identify the row. You can write queries in SQL or you can simply browse to phpMyAdmin to create database and table. The first step would be to design the database ‘library’ that has one table ‘books’. I assume that only you are going to input the data, so without focusing much on front end design, we get straight into PHP code. This isn’t a large or complicated project.
