Image is not displaying

[avirup]

<?php require_once("session_con.php");
require_once("functions.php"); 
confirm_logged_in();
//connect to the database server and the database  
dbconnect();
//session data fetching for test
$id= $_SESSION['suid'];
//echo $id;
//Get data from the prevoius page
//$id = $_GET['user_id'];
//echo $id;
//Checking the get data is valid or empty
if(!$id)
{
echo "No image available";
}
else
{
//Select image from the database
$sql="SELECT  * FROM `user_image` WHERE `user_id` ='".$id."';";
$result = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_array($result) or die(mysql_error());
$fdata = $row['FileData'];
$ftype = $row['MimeType'];
$fname = $row['FileName'];
}
//setting the header information to display the image
header('Content-type: $ftype');
echo $fdata;

?>

Omage is not displaying when i m running the page...
save option is coming...instead of displaying the image...


can anybody correct the code...coz...it's showing sometimes peculier data and last line is 
header output send already...thank You.

You need to do something like

 

imagepng ($fdata);

 

or

 

imagegif($fdata);

 

or something like that depending on what type of image it is

[kpasiva]

The script used to set header and display image content,

<?php
//setting the header information to display the image
header('Content-type: $ftype');
echo $fdata;
?>

 

has to be moved to the else part because the error msg  ("No image available") can't be displayed if session doesn't exist.

 

Check the script by moving the above script to the else part whether it shows the error - "No image available".

 

 

 

[avirup]

Thank for the reply..!!!

 

Yea I have put the last part in the else part..session is exist and thus "No image " error is not echoing.Instead of that save the file dialog box is opening .

 

when I save and open the file some peculiar data is showing there.

 

So what I will do now!!

[ranjuvs]

whats the value of $fdata?

[avirup]

value??

it's the image file which I have store as a long blob....in Mysql...

 

But when trying t fetch then showing a dialog box to save the file...

When I am opening the file with the editor...then showing unknown data.

 

 

Thank you...

I have done few changes in my code...

as previously I was fetching the userid from the session

now I wanna display the image linking from another page

 

disaply.php

<div id="photo">
      <img src="getimage.php?user_id=<?php print $user_id; ?>" width="162" height="156" /></div>

and now the getimage.php code

<?php require_once("session_con.php");
require_once("functions.php"); 
confirm_logged_in();
//connect to the database server and the database  
dbconnect();

//Get data from the prevoius page
$id = $_GET['user_id'];
//I also tried echo to display the user_id...now its not coming also

//Checking the get data is valid or empty
if(!$id)
{
echo "Image is not available";
}
else
{
//Select image from the database
$sql="SELECT  * FROM `user_image` WHERE `user_id` ='".$id."';";
$result = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_array($result) or die(mysql_error());
$fdata = $row['FileData'];
$ftype = $row['MimeType'];
$fname = $row['FileName'];

//setting the header information to display the image
header('Content-type: $ftype');
echo $fdata;
}
?>

 

Can anybody help me...now..please..!!!

It's over a week I am trying...!!!

Thank you..in advance!!!

You said the image is stored in a BLOB? What's the encoding? Can you change it to BINARY? That's what's coming to my mind right now is the encoding. I could be wrong.

[avirup]

Thanks for reply..!!!

 

I save my image file as longblob and its in binary...!!!

But still I am getting error...!!!!

 

What can be the reason??

[FVxSF]

Ahhhh I think I know what it is. Take a close look at header('Content-type: $ftype'); you're tossing a variable in a set of single quotes. change the ' to " like this header("Content-type: $ftype");

 

Additionally you can also do this: header('Content-type: ' . $ftype);

[avirup]

Thank you..but still...

 

http://localhost/getimage.php

 

is printed when i am running the file...!!!!

 

As u said I changed the header to"....

 

So now what???

[FVxSF]

Yeah, this is a weird problem you're having. One last thing I can think about is the mime type.

 

What is the mime? image/jpeg image/png?

 

can you add

 

die( $row['MimeType'] );

 

After

 

$fdata = $row['FileData'];
$ftype = $row['MimeType'];
$fname = $row['FileName'];

 

And post what that says. The only, last thing I can think of then is an invalid mime type...

And if you posted that link to show us what's going on we can't see it since it's on your localhost. Can you post an example on the web at all?

[avirup]

as you said at ur last post

 

I am sending the display  as display1

[avirup]

My first post in this thread is opening file to save...

I am sending this file

 

http://rapidshare.com/files/147537199/getimage.php.html

 

as this file is also peculier type..

 

Thank you very much for your time..

 

tell me anything what I should send u

[FVxSF]

Ok, well I saw the screen

 

http://www.imgx.org/public/view/full/11321

 

I see 10image/jpeg I don't know where the 10 came from but it should be just image/jpeg. check your database. for that entry. If you remove the 10 I think it should work.

[avirup]

sorry 10 is the id no I am echoing..nothing else

[FVxSF]

so you printed out just the mime? If so that 10 should not be there at all.

[avirup]

No actually just for checking..it's nothing....!!!

 

without that I have tried its only printing the images/jpeg

 

Thank you

[FVxSF]

Did you get it working yet then?

[avirup]

No...I am still struggling.!!!

 

I dont know...the code seeems ok...infact,...it worked soedays before,,...but now it is not working at all.

 

Thank You....!!!

[avirup]

can anybody help me about this??

 

Thank you.!!!

there really seems to be nothing wrong with your code. this may seem silly, but check that there is no whitespace outside of the php tags in your script image script and also session_con.php and functions.php
