PHP - Displaying The Same Blob Image

Hi everyone,

I've read lots of tutorials on this, but something is not clicking in my brain with it.  I think my coding is close, but, as of right now, all I get is a red x for the image when I try to display the image.  Let me share my code as a starting point - I would truly appreciate any helpful comments or blatant errors that are pointed out or shared with me.

Here is the upload image form and code (so they clicked the item name and then go into this):

if($_REQUEST['modifyfeatured'])
{
$id=$_REQUEST['modid'];

$sqlid="SELECT * FROM product WHERE id='$id'";
$resultid=mysql_query($sqlid, $dbh);
$idrow = mysql_fetch_array($resultid);

echo "<p>";
echo "Fill out the form below to add a short text line (i.e. 20% Off!) and/or an image (like the new note).<br>";
echo "You are modifying the following item: <p><b>";
echo $idrow['product_id'];
echo " ";
echo $idrow['title'];
echo "</b><p>";

?>
<table border="0" cellpadding="2" cellspacing="0">
<tr>
<td>
<form method="post" enctype="multipart/form-data">
<input type="hidden" name="id" value="<? echo $id; ?>">
Short Text Message:
</td><td>
<input type="Text" name="message"></td></tr>
<tr><td>Small Image:</td><td>
<input type="hidden" name="MAX_FILE_SIZE" value="2000000">
<input name="userfile" type="file" id="userfile"></td></tr>
<tr><td>&nbsp;</td><td>
<input name="upload" type="submit" class="box" id="upload" value="Submit">
</td></tr></table>
</form>
<?

}
//then when the click the upload link, here is the code for that:

if(isset($_POST['upload']) && $_FILES['userfile']['size'] > 0)
{
$fileName = $_FILES['userfile']['name'];
$tmpName  = $_FILES['userfile']['tmp_name'];
$fileSize = $_FILES['userfile']['size'];
$fileType = $_FILES['userfile']['type'];
$message=$_REQUEST['message'];
$id=$_REQUEST['id'];

$fp      = fopen($tmpName, 'r');
$content = fread($fp, filesize($tmpName));
$content = addslashes($content);
fclose($fp);

if(!get_magic_quotes_gpc())
{
    $fileName = addslashes($fileName);
}

include 'library/config.php';
include 'library/opendb.php';

//$query = "INSERT INTO featured_prods (name, size, type, image, message ) ".
//"VALUES ('$fileName', '$fileSize', '$fileType', '$content', '$message')";

$query="UPDATE featured_prods SET name='$fileName', size='$fileSize', type='$fileType', image='$content', message='$message' WHERE id='$id'";

//$sqldone="UPDATE product SET product_id='$product_id', title='$title', description='$description', regular_price='$regular_price', sale_price='$sale_price', stat='$stat', weight='$weight', close_out='$close', additional='$additional', additionalpix='$additionalpix_name' WHERE  id='$id'";

//$resultdone=mysql_query($sqldone, $dbh);

mysql_query($query) or die('Error, query failed'); 
include 'library/closedb.php';

echo "<br>File $fileName uploaded<br>";
} //end if upload is hit


Okay, now here is the code trying to display the image:

<? $featuredquery="SELECT * FROM featured_prods";
$featuredresult=mysql_query($featuredquery, $dbh);
while($featuredrow=mysql_fetch_array($featuredresult)){

$id=$featuredrow['id'];
$prodquery="SELECT * FROM product WHERE id='$id'";
$prodresult=mysql_query($prodquery, $dbh);
$prodrow=mysql_fetch_array($prodresult);

echo $prodrow['title'];
echo "<br>";
echo $featuredrow['message'];
echo "<br>";
?>
<img src="getimage.php?id=<?echo $id;?>" alt="cover" />
<?
}


And here is the code for getimage.php:

<?
$id=$_GET["id"];
$result = mysql_query("select image from featured_prods where id='$id'"); 
$row = mysql_fetch_row($result); 
         
$data = base64_decode($row[0]); 
         
$im = imagecreatefromstring($row[0]); 
imagejpeg($im);

header('Content-type: ' . image/jpeg); // 'image/jpeg' for JPEG images
echo $data;

?>


Again, any help would be appreciated.  I'm a real rookie here, and I appreciate everyone's time and effort to assist me very much. 

Hi!

I am building a little PHP/MySQL application where pictures are uploaded and stored in MySQL in a longblob. These are special circumstances and storing images in the database in an absolute must.

Uploading is working fine. The upload script inserts the following into the field `image_data`:
base64_encode(file_get_contents($_FILES['image']['tmp_name']))

The problem is displaying the images. I cannot for the life of me make it work. I've tried the code on multiple systems with various versions of PHP and MySQL.

I have two files: one called view.php and one called show.php.

# view.php
# It gets $info['id'] from a query getting the ID of the recent-most image uploaded. 

echo '<img src="show.php?id='.$info['id'].'" alt="" />';

# show.php
# $id is determined by $_GET['id'] and passes through security checks I've omitted here.
# There is zero (not even a whitespace) output before the header()s are sent.

$query = "SELECT `image_data`,`image_mime`,`image_size` FROM `upload`.`files` WHERE `id` = '$id';";

$sql = mysql_query($query) or die(mysql_error());

$image = mysql_fetch_assoc($sql);

header('Content-Type: ' . $image['image_mime']);
header('Content-Length: ' . $image['image_size']);

echo base64_decode($image['image_data']);

The problem is that no image is displayed either in view.php or when I call show.php directly with a valid ID. I have verified that $image['image_mime'] and $image['image_size'] contain the right data.

However, if I download show.php and change extension to for example .jpg, the image is there. So the image is stored correctly in the database and $image['image_data'] is outputting the right data.

I even compared checksums for the image before and after and they're identical, so I would conclude that the error is in the outputting of the image - but I can't figure out what.

Error_report is set to E_ALL but there's nothing useful coming out.

Any ideas?

Code: [Select]
$thephoto = $row['thePHOTO'];
in mysql thephoto is BLOB file type and stores an image

i want to display the image as an avatar, in a while loop.

Code: [Select]
while($row = mysql_fetch_assoc($query4)) {

        $id = $row['ID'];
$thename = $row['theNAME'];
$thephoto = $row['thePHOTO'];


}


how do i make blob readable and then display as an image?

it should display the image but nothing appears. what have i done wrong?

Code: [Select]
echo "<img src=\"photo.php?id=$studentid\" alt='photo' />";
photo.php
Code: [Select]
<?php

$id= $_GET['id'];

 $getphoto= mysql_query("SELECT photo FROM Student WHERE SID=$id LIMIT 1");

$row5 = mysql_fetch_assoc($getphoto);

$photogot = $row5['PHOTO'];
header("Content-type: image/gif");

   print $photogot;
 


?>

Code: [Select]
echo '<img src="data:image/jpg/png/jpeg;base64,' . base64_encode( $row['image'] ) . '" height="150" />';
This is showing up images great in firefox, safari and chrome, but in internet explorer it shows a nice red cross, and I assume it is because of the encoding?

Does anyone know how to get working in internet explorer as well?

Pretty urgent job!

Much appreciated for your help!
