PHP - Help-- Retrieve Database Values Into Iframe Src

hey i am using a MySql database and i need to create a dynamic HTML table with one of its columns as checkboxes.so i have to create multiple checkboxes.but these checkbox values are to be stored in a mysql table and then later retrieved when form reloads.and depending on previous state when form was submitted, the newly created checkboxes have to be checked in the same manner.so how do i store multiple checkbox values in my table and also how do i retrieve them?
please help.

I have this code which uoploads and resizes the images into a folder without a problem. My problem is I am unable to view the Thumb or Full image which has uploaded to the folder and the database with the other data.  How do i correct this problem code below. Thanks

I have code for displaying result from database:

foreach ($_SESSION["products"] as $cart_itm)
        {
           $product_code = $cart_itm["code"];
		   $results = $mysqli->query("SELECT * FROM products WHERE product_code='$product_code' LIMIT 1");
		   $obj = $results->fetch_object(); 

Now, I display data with: $obj->product_name     When I get the list, how to put inline numbers (1 2 3 4 ...)?   1       products1 2       products1 3       products1 4       products1..

Hi,
Im trying to retrieve HTML from a mysql database but nothing i've tried seems to work.
The HTML im trying to retrieve is an iframe with a link and styles (code from amazon associates). Im trying to display links to specific products on amazon from the product page on my site. All data about the product is retrieved from the database so i have code to select the amazon link row in my database table but i cant get it to display. It says the html isnt a string so i cant echo it, fair enough. I have tried using the following code:
Code: [Select]
$get_buylink_sql = "SELECT mobo_buylink FROM mobo WHERE mobo_id = $mobo_id";
$get_buylink_res = mysqli_query($mysqli, $get_buylink_sql)
or die(mysqli_error($mysqli));

while ($buylink = mysqli_fetch_array($get_buylink_res)) {
echo"<iframe src=\"".$buylink."\" style=\"width:120px;height:240px;\" scrolling=\"no\" marginwidth=\"0\" marginheight=\"0\" frameborder=\"0\"></iframe>";
}

mysqli_free_result($get_buylink_res);

mysqli_close($mysqli);I have also tried putting the whole iframe code in the database which didnt work either.
The mobo_id variable works fine for retrieving the rest of the data and i need to get the amazon link from the same record.

I hope i've put this in a way you can understand, but if not i'll try and explain better and give you a link to my site if needed.

Thanks,
Alex

Hello people,
I have created an application in Code Charge where my site users can login and play games online.The game code is run via flash and html. The Game has 5 stages and from a page in my application called transfertogame.php , i transfer them to the game page. Now i want to be able to track each players progress via database so that when they log back in and they get to the transfertogame.php page, it can check the page they were on before and immediately take them to the page without starting from page 1. Any help will be appreciated as i am very poor with php scripting
This is the session ID i guess is being used from my application page

//Initialize Method @4-537EA73F
function Initialize()
{

if(!$this->Visible)
return;

$this->ds->Parameters["sesUserID"] = CCGetSession("UserID");
}
//End Initialize Method

//Validate Method @4-7E1FC38C
function Validate()
{
$Validation = true;
$Where = "";
$this->CCSEventResult = CCGetEvent($this->CCSEvents, "OnValidate");
return (($this->Errors->Count() == 0) && $Validation);
}
//End Validate Method

Hi, after following lots of advice and changing to MySqli I am running into a few probs. This is me just probably missing something stupid, I know what I want, but can't figure out what query I should use and where I should place it. All the queries I have tried have failed.   I just need a query that gets the $current_stored_password from the password field on the database, to confirm the last check

elseif 
	($current_password !== $current_stored_password) {
	include 'includes/overall/header.php';
	echo $current_password . ' AND ' . $_POST['current_password'] . ' Password and password again do not match';
	include 'includes/overall/header.php';

}

Here is the whole script.

<?php
session_start();
error_reporting(0);
//ini_set('display_errors', '1');

require( 'database.php' );

$username = $_SESSION['loggedinuser'];
$current_stored_password = $_SESSION['password'];
$current_password = $_POST['current_password'];
$password = mysqli_real_escape_string($con, md5( $_POST['password']));
$password_again = mysqli_real_escape_string($con, md5( $_POST['password_again']));


// Run checks

if	(isset($_POST['current_password'], $_POST['password'], $_POST['password_again'])) {
	
if( strlen( $_POST['current_password'] ) < 8 )
    {
        include('includes/overall/header.php');
        echo "Password Must Be 8 or More Characters.";
        include('includes/overall/footer.php');
}
elseif( strlen( $_POST['password'] ) < 8 )
    {
        include('includes/overall/header.php');
        echo "Password Must Be 8 or More Characters.";
        include('includes/overall/footer.php');
    }
elseif 
		( strlen( $_POST['password_again'] ) < 8 )
    {
        include('includes/overall/header.php');
        echo "Password Must Be 8 or More Characters.";
        include('includes/overall/footer.php');
    }
elseif 
	($password !== $password_again) {
	include 'includes/overall/header.php';
	echo ' Password and password again do not match';
	include 'includes/overall/header.php';
}
elseif 
	($current_password !== $current_stored_password) {
	include 'includes/overall/header.php';
	echo $current_password . ' AND ' . $_POST['current_password'] . ' Password and password again do not match';
	include 'includes/overall/header.php';

} else {

// Define a query to run 
$query = "UPDATE `user` SET `password` = '$password' WHERE `username` = '$username'"; 

// Query the database 
$result = mysqli_query($con,$query); 

// Check if the query failed 
if( !$result ) 
{ 
   die('There was a problem executing the query ('.$query.'):<br>('.mysqli_errno($con).') '.mysqli_error($con)); 
} 

else {

include 'includes/overall/header.php';
	echo 'Password has been changed';
include 'includes/overall/footer.php';
}    
}
}

// Close the connection 
mysqli_close($con); 
?> 

At the moment the message displayed when the form is submitted is

	echo $current_password . ' AND ' . $_POST['current_password'] . ' Password and password again do not match';
 

How do I retrieve the password from the database to compare against the current password entered by the user? Any help is much appreciated.   PS. Yes I know I have repeated code and that md5 is not secure, but I am just building onto a template I got and will be making changes to shorten the code and secure the password soon    

As a complete newbie to php and webdesigning i have a following problem.I would like to retrieve the data from database and display it in a drop down menu.Then i should allow the user to select the values from drop down list along with other details,in other words i have to embed the drop down output as the form input for the user and store the form data in another table.I am running a xampp server and i am using php 5.4 version.Please help.My code is as follows.In this case project_name is displayed as the drop down output.but how do i use the same drop down output as a input in the form.

I have mysql select query shown below retrieving data from a database:

$sql = "
SELECT 
	student, sum( test_score ) as score
FROM 
	test
INNER JOIN 
	level 
ON 
	test.level_id = level.level_id
GROUP BY 
	student"
$result = $mysqli->query($sql, MYSQLI_STORE_RESULT);
if($result)
{
      while ($row = $result->fetch_array(MYSQLI_ASSOC))
       {
	    var_dump($row);
       }
}

On inspection of the retrieved array with var_dump(), i have these result below:

array (size=2)
  'John' => string 'English' (length=2)
  'Score' => string '20' (length=3)

array (size=2)
  'Mary' => string 'Math' (length=3)
  'Score' => string '35' (length=3)

array (size=2)
  'Samuel' => string 'Physics' (length=3)
  'Score' => string '5' (length=3)

 How do I get at and print out the highest score from this set of array values within this context.
 I tried this echo max($row['count']) but i understandably got this feedback:
Warning: max(): When only one parameter is given, it must be an array   Thanks.
