Putting a set of code which is pushing image to database
and fetching back from database:
<!-- <?php
error_reporting(0);
// Connect to database
$errmsg = "";
if (! @mysql_connect("localhost","root","")) {
$errmsg = "Cannot connect to database";
}
@mysql_select_db("test");
$q = <<<CREATE
create table image (
pid int primary key not null auto_increment,
title text,
imgdata longblob,
friend text)
CREATE;
@mysql_query($q);
// Insert any new image into database
if (isset($_POST['submit'])) {
move_uploaded_file($_FILES['imagefile']['tmp_name'],"latest.img");
$instr = fopen("latest.img","rb");
$image = addslashes(fread($instr,filesize("latest.img")));
if (strlen($instr) < 149000) {
$image_query="insert into image (title, imgdata,friend) values (\"".
$_REQUEST['title'].
"\", \"".
$image.
"\",'".$_REQUEST['friend']."')";
mysql_query ($image_query) or die("query error");
} else {
$errmsg = "Too large!";
}
$resultbytes='';
// Find out about latest image
$query = "select * from image where pid=1";
$result = @mysql_query("$query");
$resultrow = @mysql_fetch_assoc($result);
$gotten = @mysql_query("select * from image order by pid desc limit 1");
if ($row = @mysql_fetch_assoc($gotten)) {
$title = htmlspecialchars($row[title]);
$bytes = $row[imgdata];
$resultbytes = $row[imgdata];
$friend=$row[friend];
} else {
$errmsg = "There is no image in
the database yet";
$title = "no database image available";
// Put up a picture of our training centre
$instr = fopen("../wellimg/ctco.jpg","rb");
$bytes = fread($instr,filesize("../wellimg/ctco.jpg"));
}
if ($resultbytes!='') {
echo $resultbytes;

Above set of code has one problem.
The problem is whenever i pressing
the "submit" button. It is just displaying
the image on a page. But it is leaving all
the html codes. even any new line message after
the
// Printing image on browser
echo $resultbytes;
//************************//
So, for this i put this set of code in html tag: This is other sample code:
<!--
<?php
error_reporting(0);
// Connect to database
$errmsg = "";
if (! @mysql_connect("localhost","root","")) {
$errmsg = "Cannot connect to database";
}
@mysql_select_db("test");
$q = <<<CREATE
create table image (
pid int primary key not null auto_increment,
title text,
imgdata longblob,
friend text)
CREATE;
@mysql_query($q);
// Insert any new image into database
if (isset($_POST['submit'])) {
move_uploaded_file($_FILES['imagefile']['tmp_name'],"latest.img");
$instr = fopen("latest.img","rb");
$image = addslashes(fread($instr,filesize("latest.img")));
if (strlen($instr) < 149000) {
$image_query="insert into image (title, imgdata,friend) values (\"".
$_REQUEST['title'].
"\", \"".
$image.
"\",'".$_REQUEST['friend']."')";
mysql_query ($image_query) or die("query error");
} else {
$errmsg = "Too large!";
}
$resultbytes='';
// Find out about latest image
$query = "select * from image where pid=1";
$result = @mysql_query("$query");
$resultrow = @mysql_fetch_assoc($result);
$gotten = @mysql_query("select * from image order by pid desc limit 1");
if ($row = @mysql_fetch_assoc($gotten)) {
$title = htmlspecialchars($row[title]);
$bytes = $row[imgdata];
$resultbytes = $row[imgdata];
$friend=$row[friend];
} else {
$errmsg = "There is no image in
the database yet";
$title = "no database image available";
// Put up a picture of our training centre
$instr = fopen("../wellimg/ctco.jpg","rb");
$bytes = fread($instr,filesize("../wellimg/ctco.jpg"));
}
}

** But in this It is showing
the image in format of special charaters
and digits.
1) So, Please help me to print
the image with some HTML code. So that i can print it in my form to display
the image.
2) Is there any way to convert
the database image into real image, so that i can store it into my hard-disk
and call it from tag?
Please help me.
