Closed 2 years ago.
Here's My setup I have gone over it twice already and have come up with nothing.
I am currently working on a LAMP stack and most of the configurations have been done properly.
I have two files
1. connect.php
2. registration.php
code of connect.php is as follows:
<?php
ini_set('display_errors',1);
error_reporting(E_ALL);
$hostname="localhost"; //local server name
$username="user_name"; //mysql username
$password="my_password"; //mysql password
$database="my_database"; //database name
// Create Connection to DB using an Object
$con= mysqli_connect($hostname,$username,$password); //do i need to pass database name also as an argument to this?
//Check Connection
if(mysqli_connect_errno()){
echo"Failed to connect! due to : " . mysqli_connect_errno();
} else{
echo"Connected!";
}
?>
code of registration.php is as follows:
<?php //start php tag
include("/var/www/calculator/connect.php"); //using absolute path to avoid any confusion
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
} else {
printf("Connected! on Registration Page"); //executes till here with no problems
}
if (mysqli_query($conn, "CREATE table users"))
{
printf("Query Executed!", mysqli_affected_rows($conn))
}
mysqli_close($link);
?>
Some have suggested to take a look at the apache server logs here is the last 10 output of the logs

I need help on why my queries are not getting executed despite my code having no coding errors or query structure errors.

Answer 1

You've missed ;:
if (mysqli_query($conn, "CREATE table users"))
{
printf("Query Executed!", mysqli_affected_rows($conn)) // <---- here
}
Also, read about mysqli_connect. You should use 4 arguments, but can pass '' value in one of it.
