I am having a doubt that my code "soon to be a website" is weak or easy to hack.
I have read about SQL injection and other security issues, I came to know that the URL should not be something like: "index.php?catid=id" it must be hidden or redirected or routed.
And this is what I am trying to avoid, however, I have tried session_start(); but ended up in a mess.
I might be wrong as well, there might be no danger at all when sending the user from a page to another using anchor click here
Kindly check the code below.
header.php
<div class="header">
<div class="logo">
<a href="index.php"><img src="images/logo.jpg" alt="logo" /></a>
</div><!--logo ends-->
<div class="navigation">
<?php
$cat_sql = "SELECT * FROM category";
$cat_query = $conn->query($cat_sql);
while ($cat_results = $cat_query->fetch_array()){
$category_page = "category.php?categoryID=" .$cat_results['categoryID'];
//session_start();
//echo session_id();
echo "<a href='$category_page'>". $cat_results['name'] ." </a>";
}
CloseCon($conn)
?>
<a href="admin.php">Admin</a>
</div><!--navigation ends-->
</div><!-- Header ends here-->
dbconnect.php
$servername = "localhost";
$username = "root";
$password = "123456789";
$database = "accessories";
$conn = new mysqli($servername, $username, $password, $database);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";a
function CloseCon($conn)
{$conn -> close();}
