Inserting an image as a blob in PHP

Posted by andrewtayloruk (andrewtayloruk), 23 March 2007

Hi Graham and everyone else on the forums. I was wondering if somebody on here could help...

I've made a form upload script that inserts the data from the forms into an sql database. The thing i'm stuck on is getting the image from the final input box and putting it into the database as a blob.

*** Code below ***

<?php
if (isset($_POST['submitted'])) {

$name = trim(strip_tags($_POST['name']));

$address = trim(strip_tags($_POST['address']));

$postcode = trim(strip_tags($_POST['postcode']));

$telephone = trim(strip_tags($_POST['telephone']));

$email = trim(strip_tags($_POST['email']));

$picture = trim(strip_tags($_POST['picture']));

$dbid = mysql_connect ('localhost', 'root');

mysql_select_db('addresses',$dbid)

or die ("Cannot find database");

$query = "INSERT INTO `book` (`aid`, `name`, `address`, `postcode`, `telephone`, `email`, `picture`) VALUES ('', '$name', '$address', '$postcode', $telephone, '$email' , '$picture')";

$result = mysql_query($query,$dbid)

or die("INSERT error:".mysql_error());

echo 'Row inserted';

exit;

}

?>

<html>

<head>

<title>Data submission - db version</title>

</head>

<body>

<form enctype="multipart/form-data" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">

Name: <input name="name" /><br />

Address: <input name="address" /><br />

Postcode: <input name="postcode" /><br />

Telno: <input name="telephone" /><br />

Email: <input name="email" /><br />

Picture:<br><input type="file" name="picture" size"80" /><br />

<br><input type="submit" name="submitted" value="Submit" ></form><br>

</body>

</html>

You need to look at move_uploaded_file to move the image you've uploaded to somewhere you can read it, then read it into a string. And don't strip_tags out of the picture in any way as any binary data that looks like a tag would get damaged

Here's an image upload script that I wrote showing the bare bones ...

Code:

<?php
#%% Image upload script
if ($_REQUEST[completed] == 1) {
$newname = uniqid("whc").".jpg";
move_uploaded_file($_FILES['mailfile']['tmp_name'],
"../robdemo/$newname");
} ?>
<html>
<head><title>Upload page</title></head>
<body><h1>Image Uploader</h1>

<?php if ($_REQUEST[completed] != 1) { ?>
<b>Please upload an image</b><br>
<form enctype=multipart/form-data method=post>
<input type=hidden name=MAX_FILE_SIZE value=1500000>
<input type=hidden name=completed value=1>
Choose file to send: <input type=file name=mailfile> and
<input type=submit></form>
<?php } else { ?>
<b>Yum, Yum. I enjoyed that</b>
<?php } ?>
<hr>
Copyright, etc
</body></html>
