Save image as a blob type - php

Question

I have used MySQL to save a image as a blob type. I 'm uploading files through PHP and when I get the image back I revive only a part of it. How can I improve the max size ? (my image file size is less than 300 KB)
PHP uploader...
if($_FILES!=null && $_POST!=null){
$file = $_FILES["image"]["tmp_name"];
if(!isset($file)){
echo "Please upload an image";
}else{
$image = addslashes(file_get_contents($_FILES['image']['tmp_name']));
$image_name = addslashes($_FILES['image']['name']);
$type=$_POST['type'];
$image_size = getimagesize($_FILES['image']['tmp_name']);
if($image_size==FALSE)
echo "That's not an image.";
else
{
if(!(mysql_query("INSERT INTO store (name,image,type) values ('$image_name','$image','$type')")))
echo "Problem uploading image";
else
{
$lastid = mysql_insert_id();
echo "Image uploaded. <p /> Your image: <p /> <img id='imageId' src=get.php?id=$lastid>";
}
}
}
}
retrieving image
$id = addslashes($_REQUEST['id']) ;
$imageRow = mysql_query("SELECT * FROM store WHERE id=$id");
$image = mysql_fetch_assoc($imageRow);
$image = $image['image'];
header("Content-type: image/jpg");
echo $image;

Answer 1

You can use different types of blobs. Blob, Mediumblob, longblob, etc.

Answer 2

Use mysql_real_escape_string() to escape the image data, instead of addslashes(). addslashes() isn't meant for binary.

Answer 3

Use image like this:
<img src='file_display.php?id=<?php echo $row['id']; ?>' width='100' height='100'>
Here, $row['id'] is record primary key - id
and in file_display.php:
// some basic sanity checks
if(isset($_GET['id']) && is_numeric($_GET['id'])) {
//connect to the db
$link = mysql_connect($host, $username, $password) or die("Could not connect: " . mysql_error());
// select our database
mysql_select_db($database) or die(mysql_error());
// get the image from the db
$sql = "SELECT image FROM tbl_images WHERE id=" .$_GET['id'] . ";";
// the result of the query
$result = mysql_query("$sql") or die("Invalid query: " . mysql_error());
// set the header for the image
header("Content-type: image/jpeg");
echo mysql_result($result, 0);
// close the db link
mysql_close($link);
}
It works for me with WAMP 2.x package

Answer 4

you can use this following code ::
<?php
mysql_connect("localhost","root","") or die(mysql_error());
mysql_select_db("database") or die(mysql_error());
$id = $_GET['id'];
$sql = mysql_query(" SELECT * FROM store WHERE id=$id") or die(mysql_error());
$row = mysql_fetch_array($sql);
header('Content: image/jpeg');
echo $row['image'];
?>
