Question

I have two files [ Main.html ] and [image.php]. However [image.php] is dealing with binary data since it displays an image from the database. My question is can I and if i can how do I pass parameters into [image.php] from main?

I call image.php in main like this:

img src=”image.php” alt=”image retreived from DB”

<?php
$mysqli=mysqli_connect('localhost','root','','draftdb');
if (!$mysqli)
die("Can't connect to MySQL: ".mysqli_connect_error());


    $stmt = $mysqli->prepare("SELECT display.PICTURE_ID 
    FROM cards  
    INNER JOIN display ON cards.DISPLAY_ID = display.DISPLAY_ID 
    WHERE display.DISPLAY_ID=? AND cards.CARD_TYPE =?" );

     if( rand(1, 8) == 8) 
     {
     $cardtype='Mythic';
     $displayid=rand(1,15) ;

     }

     else
     {
     $cardtype='Rare';
    $displayid=rand(16,19) ;
     }

    $stmt->bind_param("si", $displayid, $cardtype);
    $stmt->execute();
    $stmt->bind_result($image);
    $stmt->fetch();
    header("Content-Type: image/jpeg");
    echo $image; 
    ?>

Kind of hard to make a really detailed answer here, since the simplest solution is well… simple.

Surely you’ve seen website addresses with ? and var=value&var2=anothevalue in them

You can do the same thing yourself with.

<img src="image.php?param=wat&moreparam=lolz" />

and

$param = isset($_GET['param']) ? $_GET['param'] : null;
