delete S3 bucket with AWS PHP SDK

[Tim Dunphy]

Hi All,

I am attempting to delete an empty S3 bucket using the AWS PHP SDK.

Here's how they describe the process in the docs:

$result = $client->deleteBucket(array(
// Bucket is required
'Bucket' => 'string',
));

You can find the full entry here:

AWS PHP SDK Delete Bucket
Docs<http://docs.aws.amazon.com/aws-sdk-php-2/latest/class-Aws.S3.S3Client.html#_deleteBucket>

Here's how I approached it in my code:

$s3 = new AmazonS3();

$result = $s3->deleteObject(array(
'Bucket' => $bucket_name ));

But when I run it, this is the error I get:

'Notice: Undefined index: $bucket_name in /var/www/awssdk/delete_bucket.php
on line 5 Warning: Missing argument 2 for AmazonS3::delete_object() in
/var/www/awssdk/services/s3.class.php on line 1576 Notice: Undefined

/var/www/awssdk/services/s3.class.php on line 548'


This is line 548 in the above referenced file:

// Validate the S3 bucket name
if (!$this->validate_bucketname_support($bucket))
{
// @codeCoverageIgnoreStart
throw new S3_Exception('S3 does not support "' .
$bucket . '" as a valid bucket name. Review "Bucket Restrictions and
Limitations" in the S3 Developer Guide for more information.');
// @codeCoverageIgnoreEnd
}




Has anyone played around enough with the AWS SDK to know what I'm doing
wrong here? Would anyone else be able to hazard a guess?

Thanks

Your code is failing because $bucket_name, I suspect, is null. Where do
you define this variable before you use it in this bit of code:

$result = $s3->deleteObject(array(
'Bucket' => $bucket_name ));

Hi Tim,

Is the call working? Does it actually get deleted?

This could just be an issue (which I see alot) where developers do not
check for variables or preset them before usage, causing those notices to
come up (pretty harmless most of the times).

Hey guys,

Sorry about that i should have posted the full code to give you some idea
of context. Anyway, here it is:

<?php
require_once 'sdk.class.php';
if (isset($_POST['submit'])) {

* $bucket_name = $_POST['$bucket_name'];*
// Create the S3 Object from the SDK
*$s3 = new AmazonS3();*

* $result = $s3->deleteObject(array(*
* 'Bucket' => $bucket_name ));*


// The response comes back as a Simple XML Object
// In this case we just want to know if everything was okay.
// If not, report the message from the XML response.
if ((int) $response->isOK()) {
echo '<center>Deleted Bucket';
echo '<br /><br />';
echo '<a href=listbuckets.php>List Buckets</a></center>';
} else {
echo (string) $response->body->Message;
}
//echo '<br /><br />';
}
?>
<body>
<center><h3>Delete S3 Bucket</h3>
<form name="delete_bucket" method="post" action="delete_bucket.php">
<label for="bucket_name">Bucket Name:</label><br />
* <input type="text" id="bucket_name" name="bucket_name" /><br /><br />*
<input type="submit" name="submit" value="Delete Bucket" />
</form></center>

So, as you can see I am taking the 'bucket_value' from $_POST and passing
it into the call to S3.

When the form comes up on the web I give it the name of one of my S3
buckets. The result is the following error:

Notice: Undefined index: $bucket_name in /var/www/awssdk/delete_bucket.php
on line 67 Warning: Missing argument 2 for AmazonS3::delete_object() in

I hope that clarifies my situation a bit. Sorry for not providing that

No Problem, the issue is that you referring to the invalid post element
$bucket_name as opposed to the correct on bucket_name.

*$bucket_name = $_POST['$bucket_name'];*

Should be

*$bucket_name = $_POST['bucket_name'];*

Hi Aziz,

Thank you for getting back to me!

I appreciate you spotting that error.

So I corrected that

<?php
require_once 'sdk.class.php';
if (isset($_POST['submit'])) {

* $bucket_name = $_POST['bucket_name'];*
// Create the S3 Object from the SDK
$s3 = new AmazonS3();
*
$result = $s3->deleteObject(array(
'Bucket' => $bucket_name ));*


// The response comes back as a Simple XML Object
// In this case we just want to know if everything was okay.
// If not, report the message from the XML response.
if ((int) $response->isOK()) {
echo '<center>Deleted Bucket';
echo '<br /><br />';
echo '<a href=listbuckets.php>List Buckets</a></center>';
} else {
echo (string) $response->body->Message;
}
//echo '<br /><br />';
}
?>
<body>
<center><h3>Delete S3 Bucket</h3>
<form name="delete_bucket" method="post" action="delete_bucket.php">

<input type="submit" name="submit" value="Delete Bucket" />
</form></center>
<script>
</body>
</html>


And this is the error I am currently getting:

Has anyone played around enough with the AWS SDK to know what I'm doing
wrong here? Would anyone else be able to hazard a guess?
Thanks

Hey Tim,

It seems that deleteObject takes in 2 params, and you are sending it 1
param. I would recommend you look at the documentation and make sure you
are sending the right params.

Hi Aziz,
Thank you for getting back to me!
I appreciate you spotting that error.
So I corrected that
<?php
require_once 'sdk.class.php';
if (isset($_POST['submit'])) {
* $bucket_name = $_POST['bucket_name'];*
// Create the S3 Object from the SDK
$s3 = new AmazonS3();
*
$result = $s3->deleteObject(array(
'Bucket' => $bucket_name ));*
// The response comes back as a Simple XML Object
// In this case we just want to know if everything was okay.
// If not, report the message from the XML response.
if ((int) $response->isOK()) {
echo '<center>Deleted Bucket';
echo '<br /><br />';
echo '<a href=listbuckets.php>List Buckets</a></center>';
} else {
echo (string) $response->body->Message;
}
//echo '<br /><br />';
}
?>

Not sure if I'm getting closer here... but definitely appreciate any
advice anyone may have.
Thanks!

No Problem, the issue is that you referring to the invalid post element
$bucket_name as opposed to the correct on bucket_name.
*$bucket_name = $_POST['$bucket_name'];*
Should be
*$bucket_name = $_POST['bucket_name'];*

Hey guys,
Sorry about that i should have posted the full code to give you some
<?php
require_once 'sdk.class.php';
if (isset($_POST['submit'])) {
* $bucket_name = $_POST['$bucket_name'];*
// Create the S3 Object from the SDK
*$s3 = new AmazonS3();*
* $result = $s3->deleteObject(array(*
* 'Bucket' => $bucket_name ));*
// The response comes back as a Simple XML Object
// In this case we just want to know if everything was okay.
// If not, report the message from the XML response.
if ((int) $response->isOK()) {
echo '<center>Deleted Bucket';
echo '<br /><br />';
echo '<a href=listbuckets.php>List Buckets</a></center>';
} else {
echo (string) $response->body->Message;
}
//echo '<br /><br />';
}
?>
<body>

* <input type="text" id="bucket_name" name="bucket_name" /><br /><br />*
<input type="submit" name="submit" value="Delete Bucket" />
</form></center>
So, as you can see I am taking the 'bucket_value' from $_POST and
passing it into the call to S3.
When the form comes up on the web I give it the name of one of my S3

I hope that clarifies my situation a bit. Sorry for not providing that
sooner!
Thanks

Hi Tim,
Is the call working? Does it actually get deleted?
This could just be an issue (which I see alot) where developers do not
check for variables or preset them before usage, causing those notices to
come up (pretty harmless most of the times).

Hi All,
I am attempting to delete an empty S3 bucket using the AWS PHP SDK.
$result = $client->deleteBucket(array(
// Bucket is required
'Bucket' => 'string',
));
AWS PHP SDK Delete Bucket
Docs<
http://docs.aws.amazon.com/aws-sdk-php-2/latest/class-Aws.S3.S3Client.html#_deleteBucket
$s3 = new AmazonS3();
$result = $s3->deleteObject(array(
'Bucket' => $bucket_name ));
'Notice: Undefined index: $bucket_name in

Has anyone played around enough with the AWS SDK to know what I'm doing
wrong here? Would anyone else be able to hazard a guess?
