How to view image from DB.

shnkrsv · Sun Oct 30, 2011 10:57 pm

Hai All,

Am a new to PHP, but i manage to insert an image in to my db. Now now i dont find an way to display that image in my browser.
Here my code.

<?php
$host = 'localhost';
$user = 'root';
$pw = '';
$db = 'demo';

mysql_connect($host,$user,$pw);
mysql_select_db($db);

$sql = "select img from first";//img is the field name with type:blob where the images are saved.

$result = mysql_query($sql) or die('Bad query at 12!'.mysql_error());

while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{

$dbimg1=$row['img'];
header("Content-Type: image/png");//db contains only .png image files.
echo $dbimg1;
echo "<br/>";

}

?>

And am getting the error;
The image “http://localhost/demo/img.php” cannot be displayed because it contains errors.
Please someone find me solution.

I'll send the image insert code now..

Code :

//insert.php

<?php

$hostname = "localhost"; // usually is localhost, but if not sure, check with your hosting company, if you are with webune leave as localhost
$db_user = "root"; // change to your database password
$db_password = ""; // change to your database password
$database = "demo"; // provide your database name
$db_table = "first"; // leave this as is

$db = mysql_connect($hostname, $db_user, $db_password);
mysql_select_db($database,$db);
?>

$sprice2=$_POST['sprice1'];
$eprice2=$_POST['sprice1'];
$des=$_POST['desc1'];
$img = $_POST['img1'];
$image_name = stripslashes($img);

if(!$img)
echo "This Not an Image";
else
{

$sql="INSERT INTO first VALUES('', '$name2','$url2','$sprice2', '$eprice2', '$des', '$img', '$image_name')";

if(!$result = mysql_query($sql ,$db))
echo "Problem Uploading Image File";
else
{
$lastid=mysql_insert_id();
echo "Image Uploaded Successfully.<p />Your Image :<p /><img src=get.php?id=$lastid>";
}
}

}

?>

//get.php

<?php

$db_user = "root"; // change to your database password
$db_password = ""; // change to your database password
$database = "demo"; // provide your database name
$db_table = "first"; // leave this as is

$db = mysql_connect($hostname, $db_user, $db_password);
mysql_select_db($database,$db);

//$id=addslashes($_REQUEST['id']);

$id = intval($_GET['id']); // convert string to int

$row=mysql_query("SELECT * FROM $db_table WHERE id=$id");
$image=mysql_fetch_assoc($row);
$img=$image['img'];
//header("Content-type : image/png");
echo $img;
mysql_free_result($row);

?>

This is what i needed, after inserting the data the images should retrive in the same page, but am not getting so for, so first am tried to get my image viewed by simple code. but am not getting..

Is ter any solutions found?

rupali · Mon Oct 31, 2011 3:27 am

there is a spelling mistake in "multipart" thats why it is not inserting any record. now just try this only insert.php and let me know that you get the result or not.

i haven't done any change in get.php, so just try only insert.php file and don't remove the folder upload because its necessary to uploading the images you need a separate folder for that.

shnkrsv · Mon Oct 31, 2011 3:30 am

Ya, k.. I'll try and get back to you..

shnkrsv · Mon Oct 31, 2011 3:40 am

yap, now the db is updated the image file... then how to get back to display the image..?

I dont understand why you used upload folder there.. am new to php am not so advanced..

rupali · Mon Oct 31, 2011 3:42 am

because for uploading the images we always need a separate folder to store the path for images with every person record and in the database we just only need to display on web page.

shnkrsv · Mon Oct 31, 2011 3:47 am

Oh k.. I understood... So everytime we need a folder to save our images, and as the same way we need to get back to view those images by ter names!
Thank you sooo much rupali..

rupali · Mon Oct 31, 2011 3:49 am

this is the code for get.php

<?php
$host = 'localhost';
$user = 'root';
$pw = '';
$db = 'demo';

mysql_connect($host,$user,$pw);
mysql_select_db($db);

$sql = "SELECT img FROM first";//img is the field name with type:blob where the images are saved.

$result = mysql_query($sql) or die('Bad query at 12!'.mysql_error());

while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
echo "<img src=upload/".$row['img']." height='50' width='50'><br/>";
}
//header("Content-Type: image/jpg");//db contains only .png image files.

?>

For execution of this code
path is : http://localhost/full/get.php
