[SOLVED] URL-safe Serialization

[Zaxnyd]

I need to serialize an object and pass it via URL.

 

I've tried this, and many variations of it, but nothing seems to pass seemlessly in all cases:

 

	$sSerialized = serialize($myObj);  
	$sSerialized = base64_encode($sSerialized);
	$sSerialized = urlencode($sSerialized);

	//pass via url, then on next page:

	$sSerialized = urldecode($sSerialized);
	$sSerialized = base64_decode($sSerialized);
	$myObj= unserialize($sSerialized);

 

Seems like this should be a very easy thing to do, but I can't seem to get the hang of it.

 

Thanks in advance.

what are you trying to pass?

what are you trying to pass?

 

I'm passing an object of my own design.

Why can't you pass it in a session?

[Zaxnyd]

Why can't you pass it in a session?

 

It's actually being passed via Ajax, so I don't think session would work.

 

Is there no way to make a guaranteed URL-safe, string version of any given object without the corruption of loss of the serialized data?

Most likely there are quotes (either single or double) which are being escaped by a backslash in the receiving script. Use the function stripslashes() on the incoming string before doing the unserialize.

I had my encode/decode functions output the data at each stage of the transformation.

 

I had it encode the data, then decoded it locally.  Then it passed the data via URL to be decoded again.

 

Most notable are the differences between the "As received" for the pre-pass and post-pass decodings.

base64_decode:


unserialize:

[Zaxnyd]

I tried the ajax post method and the same conversion seems to occur. 

[Zaxnyd]

Solved it.  It was the pesky plus sign that was doing it.  So I just did an eregi_replace with a placeholder and it works wonderfully.  Here's the class I made.  Some of you might appreciate it:

 

class url_serializable {
function loadFromSerial($sSerial) {
	$urldecode = urldecode($sSerial);
	$urldecode = eregi_replace("--PLUS--", "\+", $urldecode);
	$base64_decode = base64_decode($urldecode);
	$unserialize = unserialize($base64_decode);
	return $this->loadFromObject($unserialize);
}
function sSerialized() {
	$sSerialized = $this;
	$sSerialized = serialize($sSerialized);
	$sSerialized = base64_encode($sSerialized);
	$sSerialized = eregi_replace("\+", "--PLUS--", $sSerialized);
	$sSerialized = urlencode($sSerialized);
	return $sSerialized;
}
}
