I have to create a table on phpmyadmin, and then use php to make the CRUD functionality, I have done each as a separate function, but for some reason, it just won't add the data I add to the form to the table. I think that is the only error
<!DOCTYPE html>
<html>
<body>
<h1> Create</h1><br>
<form method="post">
id: <input type="number" name="id"><br>
creator: <input type="text" name="creator"><br>
title: <input type="text" name="title"><br>
type: <select name ="type">
<option value="Crime">Crime</option>
<option value="Fiction">Fiction</option>
<option value="Non-Fiction">Non-Fiction</option>
<option value="Thriller">Thriller</option>
</select><br>
identifier: <input type="text" name="identifier" value ="ISBN"><br>
date: <input type="text" name="date"><br>
language: <select name ="langauge">
<option value="en-GB">en-GB</option>
<option value="en-US">en-US</option>
<option value="fr-FR">fr-FR</option>
<option value="fr-CA">fr-CA</option>
</select><br>
description: <input type="text" name="description"><br>
<input type="submit">
</form>
Create the data to insert into the table
<?php
function create()
{
$servername = "localhost";
$username = "root";
$password = "";
$dbname="dbname";
//create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// check connection
if(!$conn)
{
die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully";
// assign variable names to take in the data and then be used
$creator = $_POST['creator'];
$title = $_POST['title'];
$type = $_POST['type'];
$identifier = $_POST['identifier'];
$date = $_POST['date'];
$language = $_POST['language'];
$description = $_POST['description'];
$sql = "INSERT INTO table (creator, title, type, identifier, date, language, description)
VALUES ($creator', '$title', '$type', '$identifier', '$date', '$language', '$description')";
if (mysql_query($conn, $sql))
{
echo "New record created successfully";
}
else
{
echo "Error: " . $sql . "<br>" . mysql_error($conn);
}
// Close the connection
mysqli_close($conn);
}
if(isset($_POST['submit']))
{
create();
}
?>
Retrieve the data from the table and display in a table output
<h1>Retrieve</h1><br>
<?php
function retrieve()
{
$servername = "localhost";
$username = "root";
$password = "";
$dbname="dbname";
//create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// check connection
if($conn ->connect_error)
{
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM table";
$result = $conn->query($sql);
if($result->num_rows >0)
{
// Outputs the table headers using echo.
echo "<table id = 'eBookTable'><tr><th>id</th><th>creator</th><th>title</th><th>type</th><th>identifier</th><th>date</th><th>language</th><th>description</th></tr>";
//output the data of each row..
while($row = $result->fetch_assoc())
{
echo "<tr><td>".$row["id"]."</td><td>".$row["creator"]."</td><td>".$row["title"]."</td><td>".$row["type"]."</td><td>".$row["identifier"]."</td><td>".$row["date"]."</td><td>".$row["language"]."</td><td>".$row["description"]."</td></tr>";
}
// Outputs the entire table, headers and data...
echo "</table>";
}
else
{
echo "0 results found";
}
// Close the connection
$conn->close();
}
retrieve();
?>
this will update the data in the table
<h1>Update</h1><br>
<!-- Use a from to update data-->
<form method ="post">
Name of Col: <input type = "text" name = "name"><br>
Replace with: <input type = "text" name = "replace"><br>
Row: <input type = "text" name = "id"><br>
<input type = "submit" value = "submit" name = "submit_Update">
</form>
<?php
function update()
{
$servername = "localhost";
$username = "root";
$password = "";
$dbname= "dbname";
$replace = $_POST['replace'];
$name = $_POST['name'];
$id = $_POST['id'];
//create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// check connection
if($conn ->connect_error)
{
die("Connection failed: " . $conn->connect_error);
}
$sql = "UPDATE table SET $name = '$replace' WHERE id = $id";
if($conn->query($sql) === TRUE)
{
echo "Record sucessfully updated";
}
else
{
echo "Error updating record: " . $conn->error;
}
$conn->close();
}
if(isset($_POST['submit_Update']))
{
update();
echo "<br> Your Updated Table";
retrieve();
}
?>
and this will delete data in the table based on the id that is inputted into the form
<h1>Delete</h1><br>
<!-- Use form to slect ID and delete the corresponding table row-->
<form method ="post">
ID: <input type = "text" name = "id"><br>
<input type = "submit" value "Delete" name = "submit_Delete">
<?php
function delete()
{
$servername = "localhost";
$username = "root";
$password = "";
$dbname= "dbname";
//create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// check connection
if($conn->connect_error)
{
die("Connection failed: " . $conn->connect_error);
}
$id = $_POST['id'];
//Sql to delete a row from the table
$sql = "DELETE FROM table WHERE id=$id";
if ($conn->query($sql) === TRUE)
{
echo "Selected record has been sucessfully deleted";
} else {
echo "Error deleting record: " .$conn->error;
}
$conn->close();
}
if (isset($_POST['submit_Delete']))
{
delete();
echo "<br>Following deletion of selected row:<br>";
retrieve();
}
?>
</body>
</html>
I'm also using XAMPP if that's any help
