I have reproduced this function:
function getTables()
{
global $db;
$value = array();
if (!($result = $db->query('SHOW TABLES'))) {
return false;
}
while ($row = $db->fetchrow($result)) {
if (empty($this->tables) or in_array($row[0], $this->tables)) {
$value[] = $row[0];
}
}
if (!sizeof($value)) {
$db->error("No tables found in database");
return false;
}
return $value;
}
in this manner:
public function getTables() {
$value = array();
$tables = array();
$sql = "SHOW TABLES";
if($stmt = $this->connect->prepare($sql)) {
$stmt->execute();
while( $row = $stmt->fetch_row() ) {
if(empty($tables) or in_array($row[0], $tables)) {
$value[0] = $row[0];
}
}
$stmt->close();
if(!sizeof($value)) {
echo 'The database has no tables';
}
return $value;
} else {
echo 'Couldn\t query the database';
}
}
But the second method returns me The database has no tables which is not true because I have one table in the db.
What is it wrong with the second method ?
In case you wonder what connect does :
public $connect;
public function __construct() {
// Define The Database Connection Or Die If Failed Connecting
$this->connect = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_NAME) or die(DB_CONNECTION_ERROR_MESSAGE);
}
It make a connection with the database. And prepare() it's a mysqli statement. I tried with query() too, same result.
Correct code. Use query instead of prepare:
public function getTables()
{
$value = array();
$tables = array();
$sql = "SHOW TABLES";
if ($res = $this->connect->query($sql))
{
while ($row = $res->fetch_row())
{
if (empty($tables) or in_array($row[0], $tables))
{
$value[] = $row[0];
}
}
if (!sizeof($value))
{
echo 'The database has no tables';
}
return $value;
}
else
{
echo 'Could not query the database';
}
}
If you still want to use prepare then you will also need $stmt->bind_result and $stmt->fetch() instead of fetch_row.
I think this piece of code is broken
$value[] = $row[0];
and probably you should change it to
$value[0] = $row[0]; or array_push($value, $row[0])

I have written a piece of code for coupon. whenever I use the function to check if the Coupon Code exists, it returns true and prints the statement. But I can't get the false return and cannot get the statement printed for false case.

if ($results > 0) {

}
}
DB table : ms_coupons
coupon_id coupon_code
1 CODE50
check_coupon.php
$coupon = $_REQUEST['coupon_code'];
if (!couponExists($coupon)) {
echo "Does not exist!";
} else {
echo "Coupon exists!";
}
when i supply coupon_code as CODE50 it prints, Coupon exists! but when i supply something different like CODE51 then the pays prints nothing.
Your problem is with this line in your code:
$results = db_rows("SELECT * from ms_coupons where coupon_code='".$cc."'") or die(db_error());
db_rows function returns number of rows, in your case it can be only two values - 1 or 0. If db_rows return 0 your script executes the die(db_error()) part (but there is no mysqli_error).
Remove the or die(db_error()) part, like this:
$results = db_rows("SELECT * from ms_coupons where coupon_code='".$cc."'");
If you want to check for mysqli_errors, move it to your db_query function.
Please i have been trying to make search in php pdo but is not working when i search it will only show the current title i searched for.
I have been using MYSQL but is showing error at the top of my page but is searching very well like i wanted it to be please can someone convert this Mysql to PDO for me or MYSQLI but i prefer PDO because i understand it more
here is my PHP to get search using mysql

Its wat everyone is saying. Keep everything by 1 extension. If u use PDO, do everything in PDO. If u use mysqli. Do everything in mysqli. Never use mysql. (we live in 2016 now).
I'm only looking at your PDO code. It seems your missing some code how do you want to get your mysql data. Your don't fetch anything. I created a similar script for you that works a little different. Including my PDO class. Test it in your own server and check it that is working.

I want to add an additional database to this script, so that the same interface can be created this second database (which is set up in exactly the same way as the first database with the same tables names, etc., but contains different data).

Is there a way to make $database a string array which I can loop over for multiple database names?
No, it does not work that way. The script you have defines a class. You have to look in the file that uses that class, where there will be something like
$interface = new DatabaseInterface("database1");
There you'll be able to do things such as
$interface = array();
$interface[0] = new DatabaseInterface("database1");
$interface[1] = new DatabaseInterface("database2");
and use two instances of the interface against the two databases.
I have a sample code:
class DBConnect {
private $connect = null;
private $query = null;
public $result = 0;
public $data = null;
public $_result;
function connect() {
$this->connect = mysql_connect(MYSQL_HOST, MYSQL_USER, MYSQL_PASS) or die("Can't connect database");
mysql_query("set names 'utf8'");
mysql_select_db(MYSQL_NAME, $this->connect);
}
function close() {
if($this->connect) {
mysql_close($this->connect);
}
}
function query($sql) {
$this->query = mysql_query($sql);
if(!$this->query) {
echo "Error: " . mysql_error();
exit;
}
}
function get_data($category_id) {
$sql = 'SELECT id, name FROM category WHERE id='.$category_id;
query($sql); // This is error
$row = mysql_fetch_object($query);
$data = $row->category;
return $data;
}
}
When I run debug is error is: Call to undefined function query() in line..., How to fix it?
You can change function query -> query1
function query1($sql) {
$this->query = mysql_query($sql);
if(!$this->query) {
echo "Error: " . mysql_error();
exit;
}
}
And then:
function get_data($category_id) {
$sql = 'SELECT id, name FROM category WHERE id='.$category_id;
$this->query1($sql); // Error has repair
$row = mysql_fetch_object($query);
$data = $row->category;
return $data;
}
In this part of your code
function get_data($category_id) {
$sql = 'SELECT id, name FROM category WHERE id='.$category_id;
$this->query($sql); // This is error -> this is suppose to
$row = mysql_fetch_object($this->query); // this also
$data = $row->category;
return $data;
}
I'm writing a class and handful of functions to connect to the database and retrieve the information from the tables. I went through previous posts having similar titles, but most of them have written using mysql functions and I am using mysqli functions.
I want somebody who can go through this simple script and let me know where I am making my mistake.
This is my class.connect.php:
<?php
class mySQL{
var $host;
var $username;
var $password;
var $database;
public $dbc;
public function connect($set_host, $set_username, $set_password, $set_database)
{
$this->host = $set_host;
$this->username = $set_username;
$this->password = $set_password;
$this->database = $set_database;
$this->dbc = mysqli_connect($this->host, $this->username, $this->password, $this->database) or die('Error connecting to DB');
}
public function query($sql)
{
return mysqli_query($this->dbc, $sql) or die('Error querying the Database');
}
public function fetch($sql)
{
$array = mysqli_fetch_array($this->query($sql));
return $array;
}
public function close()
{
return mysqli_close($this->dbc);
}
}
?>
This is my index.php:
<?php
require_once ("class.connect.php");
$connection = new mySQL();
$connection->connect('localhost', 'myDB', 'joker', 'names_list');
$myquery = "SELECT * FROM list";
$query = $connection->query($myquery);
while($array = $connection->fetch($query))
{
echo $array['first_name'] . '<br />';
echo $array['last_name'] . '<br />';
}
$connection->close();
?>
I am getting the error saying that Error querying the Database.
Few problems :-
you don't die without provide a proper mysql error (and is good practice to exit gracefully)
fetch method is only FETCH the first row
mysqli have OO method, why you still using procedural function?
The problem is either this:
public function fetch($sql)
{
$array = mysqli_fetch_array($this->query($sql));
return $array;
}
or this:
while($array = $connection->fetch($query))
Because you are using the result from the query to query again. Basically, you are doing:
$r = mysqli_query($this->dbc, $sql);
$array = mysqli_fetch_array(mysqli_query($this->dbc, $r));
And you are getting an error, because $r is not a query string. When it's converted to a string, it's a "1" (from your other comment).
Try changing the function to (changed name of variable so you can see the difference):
public function fetch($result)
{
return mysqli_fetch_array($result);
}
or just call the function directly.
If you don't do your own db abstraction for learning php and mysql, you can use Medoo (http://medoo.in/).
It's a free and tiny db framework, that could save a huge work and time.
Obviously an error occurs on SELECT * FROM list you can use mysqli_error to find the error:
return mysqli_query($this->dbc, $sql) or die('Error:'.mysqli_error($this->dbc));
This will display the exact error message and will help you solve your problem.

The mysqli_fetch_array function in your fetch method requires two parameters which are the SQL result and the kind of array you intend to return. In my case i use MYSQLI_ASSOC.
That is it should appear like this:
public function fetch($sql)
{
$array = mysqli_fetch_array($this->query($sql), MYSQLI_ASSOC);
return $array;
}
