Displaying blob pictures


SyNK

Recommended Posts

Hello all,

I know there are tons of posts on this everywhere, but none of the solutions people have given in them are working for me.

 

I'm creating a webpage that stores project information, each project can have multiple pictures showing progress. I've made it so that when you click on a project name all of the information on that project is display. Now I need to figure out how to display the pictures that have been uploaded. This is slightly problematic because not only am I displaying other things besides the pictures on the page, I'm also trying to display multiple pictures.

 

Currently, when I try to display the pictures I'm getting binary junk or the alt tag for my images. Everything else displays correctly.

 

The database we are using is phpMyAdmin 3.2.2... I assume that uses MySql, I'm not sure how to find out the version...

The blob is of type mediumblob and has the binary attribute.

The comments table has three fields: project, comment, and picture.

 

Here's my code:

 

<?php

//connect to DB

$pName = $_POST['currProj'];

if($pName != "")
{
    $query = sprintf("select * from `projects` where `name` = '$pName'");
    $result = mysql_query($query);

    // display other information

    $query = sprintf("select * from `comments` where `project` = '$pName'");
    $result = mysql_query($query);

    if(mysql_num_rows($result) >= 1)
    {
        for($i = 0; $i < mysql_num_rows($result); $i++){
            $row =  mysql_fetch_array($result);
            echo " <br /><br /><label>Picture:</label> ";
            $img = base64_decode($row['picture']);
    //        header('Content-type: image/jpeg');    // doing this displays binary/ascii mess
    //        echo $img;                                            //
            echo "<img src=\"getImage.php?count=$i&projName=$pName\" alt=\"error\" />"; // displays 'error'
            echo " <br /><label>Comment:</label> ".$row['comment'];
        }
    }
}

mysql_close($dbh);
?>

 

Code for getImage.php:

<?php
// connect to database

$num = $_GET['count'];
$pName = $_GET['projName'];

if($pName != "")
{
    $query = sprintf("select * from `comments` where `project` = '$pName'");
    $result = mysql_query($query);

    if(mysql_num_rows($result) >= 1)
    {
        for($i = 0; $i < mysql_num_rows($result); $i++){
            if($i == $count){   // only display 1 picture at a time
                $row =  mysql_fetch_array($result);
                $img = base64_decode($row['picture']);
                header('Content-type: image/jpeg');
                echo $img;
            }
        }
    }
}
else
    echo "Unknown project.";

mysql_close($dbh);
?>

 

Suggestions on what I could be doing wrong?

 

Also, apologies if this is in the wrong place.
