[Xerte-dev] Re: problem with trunk and added slashes?

Hi Ron

What would be interesting to know is whether setting a non-moodle integration path causes a problem or whether Moodle changes it...

Can you try setting the integration path to point to /functions.php

This is already included in config with a require once so should have absolutely no effect.

If all is well then the problem is in the moodle file and we need some way of mitigating the effects. If not then there must be some xerte code causing it.

Hi Tom
yes I thought the same - turning magic_quotes on isn't really the answer and for instance on the Techdis server magic_quotes has always been off and this hasn't been a problem until whatever the code change was when this started. I've actually been testing a bit after Gayan's recent message and with the latest unstable download from xerte.org.uk the following applies:

Same server, same code with guest auth enabled and crucially no moodle itegration path set all is fine.

Same server, same code even with guest auth rather than moodle auth set the problem happens if a moodle integration path is set.

Could there be a duplicate function name or variable name causing this? Or is there a way of checking if an integration path is set and if so skipping the relevant code?

Ron,

Gayan's problem is now solved, but not really the solution I wanted. magic_quotes is obsolete, so I want to find where the slashes came from in the first place.

Hi Tom
prompted by the latest message on the Xerte list from RGN Meegama (Gayan) attached I did a quick search for our previous discussion about strip slashes below. I haven't had time to investigate this but I wonder if the message from Gayan indicates why this hasn't been a problem for everyone e.g. only materialises when Moodle integration is used and even then perhaps only with a particular stripslashes setting? I've avoided upgrading any installations until I can find time to investigate and test this properly and I still don't have time to investigate now but I wonder if this helps to point you to the cause/solution? I know this is going to raise the old issue about compatibility with 3rd party applications but as I'm sure you also appreciate the fact remains in my experience next to ldap, Moodle is the next most popular solution for xot account management.
Cheers
Ron

The fact that not all people have control over this was the reason for the fix. The old code called stripslashes regardless of the settings resulting in backslashes being removed from prior escapes and LaTeX expressions.

But given your settings, I don't understand where the slashes as coming from.

Hi Tom
sorry for the delayed response been at an event all day and only just on the train home. Magic quotes settins are as follows:
magic_quotes_gpc Off Off
magic_quotes_runtime Off Off
magic_quotes_sybase Off Off

But this has been the case previously too when this wasn't a problem. I have full control over this server which has 3 separate xot installations so I could change the magic quotes settings but lots of people obviously won't have control over that e.g. on share d hosting etc

It has probable caused by r958 (2.0) and r956(trunk). What are your magic_quote settings in php.ini?

Hi all
I just replied to a message from John where I've already mentioned this but thought I should start a new thread too as this may be unrelated to the main focus of that other thread…

I updated a test install with the latest code from trunk and notice that as soon as I edited and published an LO it was adding extra slashes and thefore breaking preview/play. Here's some sample xml showing the slashes that got added to both preview.xml and data.xml

<learningObject resume=\"true\" language=\"en-GB\" name=\"Learning Object Title\" navigation=\"Linear\" textSize=\"12\" displayMode=\"default\">

            <title linkID=\"PG1371648227672\" name=\"Enter Page Title\" size=\"30\"><![CDATA[Enter title here]]></title>

            <textGraphics hidePanel=\"true\" linkID=\"PG1361433467001\" name=\"Enter Page Title\" align=\"Left\" imagesize=\"full screen\" url=\"FileLocation + \'media/800_x_516.jpg\'\" tip=\"Enter a Tooltip\" transcriptbuttonlabel=\"Transcript\"><![CDATA[Enter text for the page here]]></textGraphics>

            <textGraphics linkID=\"PG1359043029659\" name=\"Enter Page Title\" align=\"Left\" imagesize=\"full screen\" url=\"FileLocation + \'media/xpert_logo.gif\'\" tip=\"Enter a Tooltip\" transcriptbuttonlabel=\"Transcript\"><![CDATA[Enter text for the page here]]></textGraphics>

      </learningObject>

I updated an install that was already version 2 but still quite a few revisions applied so not sure what revision is causing this but I reverted the code fixed the xml from my test project and all was fine. Re-applied the code and problem returned.

Any ideas?
