Tutorial: Storing Images in MySQL with PHP / Part II / Display your images - Page 3

wendellrt · #21 (**permalink**) 09-01-2008, 09:38 AM

Hello Everyone.

When I use the example code, all I get is a blank (all white) page being displayed in my browser ('view source' displays a blank page as well).

Where did I go wrong???

You could try putting the following...

Code:

header('Content-type: image/jpg');

before the line which reads...

Code:

echo $content;

HTH.

Hi , Jaan
Can you help a newbie ?
I can upload images into the database with no problems, but retrieving them is a problem, they come out of the database in a raw form, its as if the following code is not working !

header('Content-type:image/jpg');

it does not seem to have an effect, if I delete this part of the code I get the same result! Raw data. Can you help?

Umm.. do you use the same script or you have changed it..?

If you have changed it, please post it here so I can check what's the problem

Hi Jann,

Thanks for the quick reply, here is my code.

PHP Code:


			
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>add pic</title>
</head>
<body>
<form action="insert.php" method="post" enctype="multipart/form-data" name="changer" >
<input name1="MAX_FILE_SIZE" value="102400" type="hidden">
<input name="image" accept="image/jpg" type="file">
<input value="Submit" type="submit">
</form>
</body>
</html>


php code for the page insert.php


<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>insert</title>
</head>
<?php 

// Create MySQL login values and 
// set them to your login information.
$username = "abc";
$password = "123";
$host = "localhost";
$database = "test";

// Make the connect to MySQL or die
// and display an error.
$link = mysql_connect($host, $username, $password);
if (!$link) {
    die('Could not connect: ' . mysql_error());
}

// Select your database
mysql_select_db ($database);  


// Make sure the user actually 
// selected and uploaded a file
if (isset($_FILES['image']) && $_FILES['image']['size'] > 0) { 

      // Temporary file name stored on the server
      $tmpName  = $_FILES['image']['tmp_name'];  
       
      // Read the file 
      $fp      = fopen($tmpName, 'r');
      $data = fread($fp, filesize($tmpName));
      $data = addslashes($data);
      fclose($fp);
      

      // Create the query and insert
      // into our database.
      $query = "INSERT INTO tbl_images ";
      $query .= "(image) VALUES ('$data')";
      $results = mysql_query($query, $link);
      
      // Print results
      print "Thank you, your file has been uploaded.";
      
}
else {
   print "No image selected/uploaded";
}

// Close our MySQL Link
mysql_close($link);
?>  

<body>
</body>
</html>

this works fine untill i try to get the pic out of the db......

php code for print_pic.php

PHP Code:


			
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitled Document</title>
</head>

<body>
<?php

$username = "abc";
$password = "123";
$host = "localhost";
$database = "test";

@mysql_connect($host, $username, $password) or die("Can not connect to database: ".mysql_error());

@mysql_select_db($database) or die("Can not select the database: ".mysql_error());

//$id = $_GET['id'];


$id = 1; // just a test id to see if it works!

if(!isset($id) || empty($id)){
die("Please select your image!");
}else{

$query = mysql_query("SELECT * FROM tbl_images WHERE id='".$id."'");
$row = mysql_fetch_array($query);
$content = $row['image'];

header('Content-type: image/jpg');
echo $content;

}

?> 
</body>
</html>

I hope you can help.

Thanks Bill.

please use the php tags.

this is a special php file when you output the picture, it may not contain any html as it's a picture you're returning, not a web page.

remove everything before <?php and after ?> and it will work. make extremely sure that there are absolutely no letters, spaces or any other symbols before the <?php otherwise, the system might believe it's a web page and goes nuts.
