php undefined index error mysql css if statement
Question
I am coding a web application using php html and a MySQL database. I am trying to implement an if, where if that row in the database has a certain value it will change the CSS of how it is displayed. So in my database there are projects and if a project is completed (com = "yes") it should display in green. In dbconnect.php I have the following:
<?php
session_start();
$username = "";
$email = "";
$projtitle = "";
$deadline = "";
$del1 = "";
$del2 = "";
$del3 = "";
$errors = array();
//Connect to the database
$db = mysqli_connect('localhost', 'root', '', 'hons');
//If the add project button is clicked
if(isset($_POST['addproj'])) {
$projtitle = mysqli_real_escape_string($db, $_POST['projtitle']);
$del1 = mysqli_real_escape_string($db, $_POST['del1']);
$del2 = mysqli_real_escape_string($db, $_POST['del2']);
$del3 = mysqli_real_escape_string($db, $_POST['del3']);
$deadline = mysqli_real_escape_string($db, $_POST['deadline']);
$colour = mysqli_real_escape_string($db, $_POST['colour']);
//Insert into the database
$sql = "INSERT INTO projects (title, del1, del2, del3, deadline)
VALUES ('$projtitle', '$del1', '$del2', '$del3', '$deadline')";
mysqli_query($db, $sql);
};
//If the project complete button is clicked
if(isset($_POST['projcom'])) {
$com = yes;
//Insert into database
$sql = "INSERT INTO evals (com)
VALUES ('$com')";
mysqli_query($db, $sql);
};
//If the project not complete button is clicked
if(isset($_POST['notcom'])) {
$com = no;
//Insert into database
$sql = "INSERT INTO evals (com)
VALUES ('$com')";
mysqli_query($db, $sql);
};
And here is my actual web page code:
<?php
session_start();
if(!isset($_SESSION['username'])){
$_SESSION['msg'] = "You must log in first";
header('location: index.php');
}
if(isset($_GET['logout'])){
session_destroy();
unset($_SESSION['username']);
header("location: index.php");
}
?>
<?php include ('dbconnect.php') ?>

</html>
The errors keep pointing me to lines where I have the if statements for project complete yes or no (com = yes and com = no). If anyone knows how to fix this or has a easier suggestion on how to change the styling I would really appreciate it!

你需要在像com =='yes'这样的引号中写是或否
