PHP - How To Convert Mysql Data Into Variables?

Hi, I am trying to convert the register & login script from mysql to mysqli. I have converted the easy parts and have the connection to the database, but the following functions all need changing and I can't work out the correct solution mainly due to the deprecation of mysql_result()

The code that needs updating is
 

<?php
function user_count() {
	return mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `active` = 1"), 0);
}

function users_online() {
	return mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `logged_in` = 1"), 0);
}

function change_profile_image($user_id, $file_temp, $file_extn) {
	$file_path = 'images/profile/' . substr(md5(time()), 0, 10) . '.' . $file_extn;
	move_uploaded_file($file_temp, $file_path);
	mysql_query("UPDATE `users` SET `profile` = '" . mysql_real_escape_string($file_path) . "' WHERE `user_id` = " . (int)$user_id);
}

function has_access($user_id, $type) {
	$user_id 	= (int)$user_id;
	$type 		= (int)$type;
	
	return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `user_id` = $user_id AND `type` = $type"), 0) == 1) ? true : false;
}

function activate($email, $email_code) {
	$email 		= mysql_real_escape_string($email);
	$email_code = mysql_real_escape_string($email_code);
	
	if (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = '$email' AND `email_code` = '$email_code' AND `active` = 0"), 0) == 1) {
		mysql_query("UPDATE `users` SET `active` = 1 WHERE `email` = '$email'");
		return true;
	} else {
		return false;
	}
}

function user_exists($username) {
	$username = sanitize($username);
	$query = mysql_query("SELECT COUNT('user_id') FROM `users` WHERE `username` = '$username'");
	return (mysql_result($query, 0) == 1) ? true : false;
}

function email_exists($email) {
	$email = sanitize($email);
	return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = '$email'"), 0) == 1) ? true : false;
}

function user_id_from_username($username) {
	$username = sanitize($username);
	return mysql_result(mysql_query("SELECT `user_id` FROM `users` WHERE `username` = '$username'"), 0, 'user_id');
}

function user_id_from_email($email) {
	$email = sanitize($email);
	return mysql_result(mysql_query("SELECT `user_id` FROM `users` WHERE `email` = '$email'"), 0, 'user_id');
}

function login($username, $password) {
	$user_id = user_id_from_username($username);
	
	mysql_query("UPDATE `users` SET `logged_in` = 1 WHERE `user_id` = $user_id");

	$username = sanitize($username);
	$password = md5($password);
	
	return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `username` = '$username' AND `password` = '$password'"), 0) == 1) ? $user_id : false;
}

?>

And here is what the converter gave me:

function user_count() {
return mysql_result(mysqli_query($GLOBALS["___mysqli_ston"], "SELECT COUNT(`user_id`) FROM `users` WHERE `active` = 1"), 0);
}

function users_online() {
return mysql_result(mysqli_query($GLOBALS["___mysqli_ston"], "SELECT COUNT(`user_id`) FROM `users` WHERE `logged_in` = 1"), 0);
}

function change_profile_image($user_id, $file_temp, $file_extn) {
    $file_path = 'images/profile/' . substr(md5(time()), 0, 10) . '.' . $file_extn;
    move_uploaded_file($file_temp, $file_path);
    mysql_query("UPDATE `users` SET `profile` = '" . mysql_real_escape_string($file_path) . "' WHERE `user_id` = " . (int)$user_id);
}

function has_access($user_id, $type) {
    $user_id     = (int)$user_id;
    $type         = (int)$type;
    
    return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `user_id` = $user_id AND `type` = $type"), 0) == 1) ? true : false;
}

function activate($email, $email_code) {
    $email         = mysql_real_escape_string($email);
    $email_code = mysql_real_escape_string($email_code);
    
    if (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = '$email' AND `email_code` = '$email_code' AND `active` = 0"), 0) == 1) {
        mysql_query("UPDATE `users` SET `active` = 1 WHERE `email` = '$email'");
        return true;
    } else {
        return false;
    }
}

function user_exists($username) {
    $username = sanitize($username);
    $query = mysql_query("SELECT COUNT('user_id') FROM `users` WHERE `username` = '$username'");
    return (mysql_result($query, 0) == 1) ? true : false;
}

function email_exists($email) {
    $email = sanitize($email);
    return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `email` = '$email'"), 0) == 1) ? true : false;
}

function user_id_from_username($username) {
    $username = sanitize($username);
    return mysql_result(mysql_query("SELECT `user_id` FROM `users` WHERE `username` = '$username'"), 0, 'user_id');
}

function user_id_from_email($email) {
    $email = sanitize($email);
    return mysql_result(mysql_query("SELECT `user_id` FROM `users` WHERE `email` = '$email'"), 0, 'user_id');
}

function login($username, $password) {
    $user_id = user_id_from_username($username);
    
    mysql_query("UPDATE `users` SET `logged_in` = 1 WHERE `user_id` = $user_id");

    $username = sanitize($username);
    $password = md5($password);
    
    return (mysql_result(mysql_query("SELECT COUNT(`user_id`) FROM `users` WHERE `username` = '$username' AND `password` = '$password'"), 0) == 1) ? $user_id : false;
}

?>

Please could someone point me in the right direction here?     Also my site works perfectly well with MySQL, do I have to convert it to MySQLi?   Many Thanks   Paul If anyone knows how to solve this, it would be much appreciated. I already have a website template and would prefer to continue with mysqli instead of PDO.

Many Thanks

Paul

Hello guys,
I have purchased a new book for PHP called Professional PHP 6. But the bad news is that the whole book was written for PostgreSQL NOT for MYSQL which I'm familiar with!

I have this code, I have tried to do so many things to get it working! but nothing seems to have it working!
Long story short, I have failed to convert the code to work with MySQL!

Here is my code, in case some one will offer a help, or a reference to go to if some similar case comes up on my way.

<?php
class Widget {

private $id; 
private $name; 
private $description; private $hDB; 
private $needsUpdating = false;

public function __construct($widgetID) { 
//The widgetID parameter is the primary key of a 
//record in the database containing the information 
//for this object
//Create a connection handle and store it in a private member variable 
//This code assumes the DB is called "parts" 
$this->hDB = pg_connect('dbname=parts user=postgres'); 
if(! is_resource($this->hDB)) {
throw new Exception("Unable to connect to the database.");
}
$sql = "SELECT name, description FROM widget WHERE widgetid = $widgetID";
$rs = pg_query($this->hDB, $sql); 
if(! is_resource($rs)) {
throw new Exception("An error occurred selecting from the database.");
}
if(! pg_num_rows($rs)) {
throw new Exception("The specified widget does not exist!");
}
$data = pg_fetch_array($rs); 
$this->id = $widgetID;
}

public function getName() { 
return $this->name;
}

public function getDescription() { 
return $this->description;
}

public function setName($name) { 
$this->name = $name; 
$this->needsUpdating = true;
}

public function setDescription($description) { 
$this->description = $description; 
$this->needsUpdating = true;
}
public function __destruct() { 
if($this->needsUpdating) {
$sql = "UPDATE widget SET "; 
$sql .= "name = " .  pg_escape_string($this->name) . ", "; 
$sql .= "description = " . pg_escape_string($this->description) . ""; 
$sql .= "WHERE widgetID = " . $this->id;
$rs = pg_query($this->hDB, $sql);
}
pg_close($this->hDB);
}
}
?>



FYI: I have tried mysql_pconnect ! results => failure!
I have tried replacing the prefix "pg" to "mysql" or "mysqli"! results => failure!
I have tried switching parameters, say in pg_query($resource, $query) TO mysql_query($query, $resource)  results => failure too!




Thank you in advance!

Hi, I have a connection set up to an API using a PHP script - the API sends back data in JSON format, and if I capture it and echo it, it displays in extremely unfriendly format on the screen.

I've tried to find a way to convert this data into readable format, ideally in a HTML table, but although there are articles on converting manually inputted JSON data into a HTML table using Javascript, I can't find a way to do it from a PHP variable.

This is what I have so far:

if ($_POST['getcompany']) {
$companyname = $_POST['_Name'];
	
$ch = curl_init();

$data_array2 =  array(
      'token' => $token
);
$make_call2 = json_encode($data_array2);
	//echo 'Token is '.$token;
	$token2 = substr($token, 14);
	$token3 = substr($token2, 0, -3);
	
	//echo 'Token 2 is '.$token3;
	//echo 'Company Name is '.$companyname;

//curl_setopt($ch, CURLOPT_GET, 1);
//curl_setopt($ch, CURLOPT_POSTFIELDS, $make_call2);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json','Authorization: '.$token3.'')); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'https://connectionurl?countries=GB&name='.$companyname);

//Execute the request
$result = curl_exec($ch);

echo 'Companies: '.$result; //This displays the data provided by the search, but is in JSON format

 

So I need a way to get the data held in $result, into a HTML table. Any idea how I can do this?

I've been playing around with this code from http://v3.thewatchmakerproject.com/journal/276/building-a-simple-php-shopping-cart

Objective: I'm trying to make the scripts work but without pulling the data from MySQL Database.
Instead, I created an array and inserted some info there and trying to replicate the same results but getting confused.

For example, on the Index.php file, I made the following changes:


<?php

// Start the session
session_start();

// Include functions
require_once('inc/functions.inc.php');

// Products multidimensional Array
$products = array("book" => array(  'id' => '1',
                                    'title' => 'Learn Your ABC\'s',
                                    'author' => 'John Doe',
                                    'price' => '14.95'),
                    "video" => array('id' => '2',
                                    'title' => 'Visual Guide to learn',
                                    'author' => 'Adam Smith',
                                    'price' => '21.38'),
                    "puzzle" => array('id' => '3',
                                    'title' => 'Can You Solve?',
                                    'author' => 'Sara Brown',
                                    'price' => '9.41'),
                    "exam" => array('id' => '4',
                                    'title' => 'Test Your Knowledge',
                                    'author' => 'Kim Carver',
                                    'price' => '11.15'));

Also, I included the zipped file of the entire script setup.

Again, I'm trying to figure out how to make the cart work with using an array for the product instead of MySQL database.
My goal is to remove ALL SQL statements from the scripts but stuck with the looping portion to display the title, author, and price from the array as shown above.

Hello to all,

I have problem figuring out how to properly display data fetched from MySQL database in a HTML table.

In the below example I am using two while loops, where the second one is nested inside first one, that check two different expressions fetching data from tables found in a MySQL database. The second expression compares the two tables IDs and after their match it displays the email of the account holder in each column in the HTML table.

The main problem is that the 'email' row is displayed properly while its while expression is not nested and alone(meaning the other data is omitted or commented out), but either nested or neighbored to the first while loop, it is displayed horizontally and the other data ('validity', 'valid_from', 'valid_to') is not displayed.'

Can someone help me on this, I guess the problem lies in the while loop?
Here is part of the HTML code:

<thead>
 <tr>
 <th data-column-id="id" data-type="numeric">ID</th>
 <th data-column-id="email">Subscriber's Email</th>
 <th data-column-id="validity">Validity</th>
<th data-column-id="valid_from">Valid From</th>
 <th data-column-id="valid_to">Valid To</th>
</tr>
</thead>

Here is part of the PHP code:

 

    <?php
    while($row = $stmt->fetch(PDO::FETCH_ASSOC))
    {
        echo '
            <tr>
                <td>'.$row["id"].'</td>
        ';
        while ($row1 = $stmt1->fetch(PDO::FETCH_ASSOC)) {
        echo '
                <td>'.$row1["email"].'</td>
        ';
        }
        if($row["validity"] == 1) {
            echo '<td>'.$row["validity"].' month</td>';
        }else{
            echo '<td>'.$row["validity"].' months</td>';
        }
        echo '  <td>'.$row["valid_from"].'</td>
                <td>'.$row["valid_to"].'</td>
        </tr>';
    }
    ?>

P.S. Please know that I have purposely omitted the connection part and the methods in the class that are used in this code to keep the spot of the problem as clean as possible. If you need me to rephrase the question, please ask.

Thank you.

This could be PHP or MySql so putting it in PHP forum for now...
I have code below (last code listed) which processes a dynamically created Form which could have anywhere from 0 to 6 fields.  So I clean all fields whether they were posted or not and then I update the mySQL table.

The problem with this code below is that if, say, $cextra was not posted (i.e. it wasnt on the dynamically created form), then this code would enter a blank into the table for $cextra (i.e. if there was already a value in the table for $cextra, it gets overwritten, which is bad).

What is the best way to handle this?  I'm thinking i have to break my SQL query into a bunch of if/else statements like this...

Code: [Select]
$sql = "UPDATE cluesanswers SET ";
if (isset($_POST['ctext'])){
echo "ctext='$ctext',";
} else {
//do nothing
}
and so on 5 more times....

That seems horribly hackish/inefficient.  Is there a better way?

Code: [Select]
if (isset($_POST['hidden']) && $_POST['hidden'] == "edit") {

$cimage=trim(mysql_prep($_POST['cimage']));
$ctext=trim(mysql_prep($_POST['ctext']));
$cextra=trim(mysql_prep($_POST['cextra']));
$atext=trim(mysql_prep($_POST['atext']));
$aextra=trim(mysql_prep($_POST['aextra']));
$aimage=trim(mysql_prep($_POST['aimage']));


//update the answer edits
$sql = "UPDATE cluesanswers SET ctext='$ctext', cextra='$cextra', cimage='$cimage', atext='$atext', aextra='$aextra', aimage='$aimage'";
$result = mysql_query($sql, $connection);
if (!$result) {
die("Database query failed: " . mysql_error());
} else {
}

Hi I am trying to select and order data/numbers from a colum in a mysql data base however i run the code and it returns no value just a blank page no errors or any thing so i think the code is working right but then it returns no result? Please help thanks

Here is the code:

<?php
$host= "XXXXXX";
$mysql_user = "XXXXXX";
$mysql_password = "XXXXXX";
$mysql_database = "XXXXXXX";

$connection = mysql_connect("$host","$mysql_user","$mysql_password") or die ("Unable to connect to MySQL server.");
mysql_select_db($mysql_database) or die ("Unable to select requested database.");

$row = mysql_fetch_assoc( mysql_query( "SELECT XP FROM Game ORDER BY number DESC LIMIT 1" ) );
$number = mysql_result(mysql_query("SELECT XP FROM Game ORDER BY number DESC LIMIT 1"), 0);

echo "The the highest XP is $number";

hi guys, im new to this forum

I'm new also to php, I need help from you guys:

I want to display personal information from a certain person (the data is on the mysql database) using his name as a link:

example:
               (index.php)
               names
                          1. Bill Gates
                          2. Mr. nice Guy
           
i want to click Bill Gates
 
   (output.php)
     Name: Bill Gates
     Country:xxxx
     Age: xx   
                 etc.

How can i make this or how to learn this?
   
                 

             
               

   
       

I'm new to PHP and I have an html page I would like to pull specific data into certain areas on the page that I will modified for php.

Here are some details. The page is a static html page that has the prices of 40+ products in a standard <li> list. When I update the prices in our database through our shopping cart, I have to change these prices manually in the html. https://www.novon.co...mic_mixers.html. It would be great if I could link the field for Base_Price in the products table to each affiliated <li> tag,

I am pulling all the data I need into ($results) and can display it all but I don't know how to get just the single products Base_Price in my <li> tag. <?=$row['Base_Price'] ?>

I know this code is not correct but to get the point across, can I create a variable that I define in each <li> tag with a statement like,,,, <?=$row['Base_Price with Product_Code=123456'] ?>

I could create a new SQL query for each <li> like "SELECT Base_Price from Products WHERE Product_Code='123456' ", but that's a lot of calls to the DB and a lot of code on the page.

And just so I weed out the hard core coders, I can not rebuild the entire page. This is too big of a project for me and my limited coding with PHP.

Can anyone help??
Thanks in advance
Michael

Hey all,

I am having a situation where I have a singleton class with a static array in it.  I insert an element into that array, and then I redirect the user to another page.  At that page, I then retrieve that array (it's stored in the session vars), but the array is then empty when I retrieve it.  I can't figure out why.

Here are some pertinent code snippets.

First, the class with the static array:

class Logger
{

private static $instance = NULL;

private static $messages = array();

//Private constructor to prevent this class from being instantiated multiple times

private function __construct()

{

}

//The clone function is private to prevent cloning of this class

private function __clone()

{

}

//Returns the singleton instance of this class

public static function GetInstance()

{

if (!self::$instance)

{

self::$instance = new Logger;

}

return self::$instance;

}

public static function GetMessageCount()

{

return count(self::$messages);

}

public static function LogMessage($new_message)

{

self::$messages[] = $new_message;

}

public static function GetMessages()

{

return self::$messages;

}

public static function ClearMessages()

{

self::$messages = array();

}
}


Here is the code where I insert something into the aformentioned array (the process is that a user tries to log in, but the login fails, and so we insert a message into the array saying that the login credentials failed).


//Retrieve the message logging instance from the session data to be able to pass messages to the user.
$message_log = $_SESSION['user_messages'];
$user = $_SESSION['user_account'];

//Create a new instance of the database management class and
//try to connect to the database
$dbm = new DBM();
if ( !$dbm->isConnected() )
{

$message_log::LogMessage("We are sorry, but we are unable to access the database at this time.  Please try again later.");
}
else
{

//Retrieve the user login information

$useremail_dirty = $_POST['useremail'];

$password_dirty = $_POST['userpassword'];

//Check to see if the email we were given exists in the database, and if the password matches

$doesPasswordMatch = $dbm->doesPasswordMatch ( $useremail_dirty, $password_dirty );

if ( $doesPasswordMatch )

{

//Correct login information was received.  Login the user and redirect appropriately.

$user->Login();

header ( "Location: ".BASE_URL."/userpage.php" );

exit;

}

else

{

//If an incorrect email or password was given, report that information to the user.

$message_log::LogMessage("Incorrect login information.");

}
}

//The user has failed to login.  Redirect to the appropriate page.
header ( "Location: ".BASE_URL."/loginfailed.php" );


And finally, given an unsuccessful login attempt, this is where I pick back up the array of messages to display the messages to the user:

$message_log = $_SESSION['user_messages'];
$all_messages = $message_log::GetMessages();

print $message_log::GetMessageCount()."<br>";
print count($all_messages)."<br>";

foreach ($all_messages as $message_string)
{

$prepared_string = prepare_text_for_html_output($message_string);

echo $prepared_string."<br>";
}

$message_log::ClearMessages();


Unfortunately, the "all_messages" variable has nothing in it...it's like the messages that I logged in the previous PHP script never even existed.  I am calling session_start, so don't worry about that (even though it's not seen in these code snippets).  What could be going wrong?

warning: I'm a self taught advanced newbie.

I'm working on a multipage PHP app that has need to pass values between pages, usually very small text strings or small integers.  I've designed it primarily using _SESSION variables to pass these bits of data.  Some of them are written to SQL, but most of them are temporary in nature.

Is using _SESSION variables in this capacity considered reasonable?  Is there something else or a different way to go about this?

(Page A writes a value into $_SESSION['myvalue'], and then page B grabs that data and does something with it.)

ARRAY Example scaled down to two (renamed example only) fields

$data = array(
"field1" => "Text within quotes processes OK",
"field2" => "Text within quotes processes OK"
);

The frustating thing has been trying to figure out how to
substitute actual text data contained in these 2 example
variables to use data from a MySQL query:

$text1 = $db_field['sampletext1'];
$text2 = $db_field['sampletext2'];

I have tried:

$data = array(
"field1" => $text1,
"field2" => $text2
);

*** (AND) ***

$data = array(
"field1 => '$text1',
"field2 => '$text2'
);

But neither approach works, even though the text in both
$text1 and $text absolutely works IF I (manually) type the
actual text within double-quotes like this:

$data = array(
"field1 => "text1",
"field2 => "text2"
);

I also tried using strval but that did not work.

So how on earth to get the (actual) text from $text1 and
$text2 into the two array fields as-if the contained text
would  (manually) be typed in double-quotes is the Mystery.

It is probably something simple, so maybe I don't know
exactly what to search for in seeking code snippet examples?

Thanks for any enlightenent.

Hello all,

I'm hoping someone can help me out. Here is the code I have for a page that contains a user form:


<?php
include "include/dbc.php";

include "include/header.inc";
?>

<style type="text/css">
.mydate{
color:#00F;
text-decoration:underline;
cursor:pointer;
}
</style>

<script type="text/javascript">
function displayDate(d){
var date=new Date();
var D=date.getDate();
date.setDate(D+d);
var YYYY=date.getFullYear();
var MM=date.getMonth()+1;
MM<10?MM='0'+MM:null;
var DD=date.getDate();
DD<10?DD='0'+DD:null;
var span=document.getElementById('date');
span.innerHTML= 'Entries for '+MM+'/'+DD+'/'+YYYY;
}
onload=function(){displayDate(0)};
</script>

<h1>Food Diary</h1>

<div class="full">
<center><div><span class="mydate" onclick="displayDate(-1)"><img src="images/left_arrow.png" border="0">Yesterday</span>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<span id="date" style="font-size:2em;"></span>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<span class="mydate" onclick="displayDate(1)">Tomorrow<img src="images/right_arrow.png" border="0"></span></div><br />

        <td class="cp_Distance"><div></div></td>

And here is the page that the user information is supposed to be passed to:


<?php
include "include/dbc.php";
include "include/header.inc";
$duration = $_POST["duration['.$row['Name'].']"];
echo '<h1>Added Activities</h1>';
echo $duration;
?>


Well, this isn't working for me. The second page code returns this error:


Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING


When I execute print_r, the values are returned to me. So I have two questions:

1) What do I need to do to change the code on the 2nd page to echo and POST the array?

2)The database contains multiple exercises under the same name. So, when the variables are passed to the 2nd page. All the values are returned regardless of whether they have been filled out or not. What can be done to only returned the user input and not the blank variables?

Hi,

I'm only just getting started with php and mysql but I like to go off the deep end.

something is wrong with my script.

it seems to work up untill it comes to the UPDATE part. It wont actually update the table and the mysql_affected_rows bit returns -1 I've searched for an explanation and can't find one.

Can someone tell me what I'm doing wrong

Thanks.
