Nothing shows up with WHERE clause mySQL - php

Question

I'm trying to put through a basic search through my Database based on a user entry, and I could not get it to work, so I'm doing a hard coded search just so I can get it to work... and I can't. My code is as follows:
<?php
$db_connection = mysqli_connect("HOST", "USERNAME", "PASSWORD", "DATABASE");
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$data = mysql_query($db_connection, "SELECT * FROM card_collection WHERE ID='1207409700'");
while( $card = mysql_fetch_array( $data ) ) {
echo $card['Name'], '<br />';
}
mysql_close();
?>
I've double checked spelling for everything linked to the database. The ID I'm basing my search from is the first item in my database.

Answer 1

You are using the mysqli_connect to database and then you are using the mysql_query to execute the query it should be mysqli_query
You code should be:
$data = mysqli_query($db_connection, "SELECT * FROM card_collection WHERE ID='1207409700'");
while( $card = mysqli_fetch_array( $data ) ) {
echo $card['Name'], '<br />';
}
mysqli_close();
Replace the mysql with the mysqli. This may be your problem.

Answer 2

I personally use PDO and not mysqli, but is the problem perhaps that you use mysql_query and mysql_fetch_array, instead of mysqli_query and mysqli_fetch_array? Note the missing i
Edit: dangit, beat to the punch :)

Answer 3

<?php
$db_connect = mysqli_connect("host", "user", "pass", "db");
if($db_connect){
$data = mysqli_query($db_connection, "SELECT * FROM card_collection WHERE ID='1207409700'");}
else {"Not Connected to db";}
while( $card = mysqli_fetch_array( $data ) ) {
echo $card['Name'], '<br />';
}
mysqli_close();
?>
