[Xerte] Xerte Toolkits - Project properties - Media and quota-can't delete files not in use

Tue Jun 9 13:27:34 BST 2009

Hello Pat,

I have installed firebug and fiddler.

On opening the project properties and then selecting the Media and Quota
tab -

After Internet Explorer throws a box that has a blue title bar that just
says "Error" and which contains the text "A Runtime Error has occurred.
Do you wish to debug?

Line: 0 
Error: Expected hexadecimal digit

If I choose to debug and click the Yes button The visual Studio just in
time debugger box opens to offer me a choice of Microsoft Script Editor
or Visual Studio 2005

However at the top of this dialogue box is the text "An unhandled
exception ('Unhandled Exception') occurred in iexplore.exe [5528]"

I have not been able to establish what that might mean.

I used fiddler to extract the code that had been generated for the media
and quota page and created a html file that I ran from the xertetookits
folder.

The same errors occurred. When I broke the text down into individual
lines the errors were reported consistently against the line immediately
preceding the onclick event which is part of the following code block.

The code block below is copied from fiddler un-edited.
I could be wrong here but it looks to me that there may be two potential
issues

1.	
	an extra " after the closing ) in the delete_file call
2.	
	a mixing of back and forward slashes in the file reference

<div class="fileinuse notfound notfoundtextcolor">
Not in use 
<img alt="Click to delete" title="Click to delete"
onclick="javascript:delete_file('C:\xampp\htdocs\xertetoolkits\USER-FILE
S/5-john.kemp-Nottingham/media/xerteTest1.flv')" " align="absmiddle"
src="website_code/images/delete.gif" />
</div>

Changing all the slashes to back slashes and removing the extra " did
not prevent the Internet Explorer error, though changing the onclick
event to onclick="" did stop the error which suggests that the error is
something to do with the call to delete_file(). Incidentally in Firefox
removing the extra " and changing to all back slashes did cause firefox
to pause when the red x was clicked as if it was trying to do something,
but the file was not deleted (possibly because I was working with
extracted code and something else was needed to enable the process to be
completed. 

I don't know if this gives you any ideas what may be happening.

The only other thought I had regarding why firefox was not deleting the
file was if there is a file permission issue preventing the deletion.
Should I be using a htaccess file in order to make the deletion
possible? Could there be something incorrect in my apache configuration
to cause the mixing of back and forward slashes?

Kind regards

Johnathan

Hello,

Testing in IE8 it works here - and I get a red X displayed.

Testing in Firefox 3.0.8 it works here - and I get a red X displayed.

Looking at the code in
website_code/php/properties/media_and_quota_template.php - there is no
hex in there (it's all styled from CSS) - is the error you're getting
JS, PHP, or something else?

If you're in firefox could you install firebug? That will watch the PHP
and let you know any JS errors. In IE you could install fiddler as well.

Thanks

Pat

-can't delete files not in use

Hello Xerte Team,

I have a test Xerte on-line Toolkits set up running and am setting up a
few projects to show colleagues how to use Xerte.

In the Project Properties / Media and Quota section there are several
files listed as "not in use". These are .swf and .flv files that I
loaded into project pages and then as I carried on testing I edited the
pages and loaded different files, so the original ones became redundant.

In Firefox 3.0.5 when I click on the red X an alert box pops up asking
"Are you sure you want to delete this file?" with OK or Cancel options.

When I click on OK the alert box disappears but nothing else seems to
happen. The file I want to delete is still there, even if I completely
close down my browser windows and start afresh.

In Internet Explorer version 7.0.5730.11, when I open project properties
/ media and quota the quota details are displayed, save that place
markers are shown instead of the red x and an error message is displayed
"A runtime error has occurred. Do you wish to Debug? Line: 0 Error:
Expected hexadecimal digit". If I elect not to debug the first red x is
displayed and the error message is shown again, always for Line: 0. This
repeats until every red x is finally displayed. However once displayed,
whilst the tooltip shows for the red x nothing happens if you click on
them, i.e. no alert box is displayed and the file is not deleted.

Is this likely to be something wrong with the way I have things
configured, or is there an error in the Xerte on-line Toolkits code?

I am running on windows with an xampp installation.

Kind regards

Johnathan
