Hi,

I am just attempting to install the gizmo block into my moodle and during the 2nd step of going to the admin page this error comes up at top of screen:

 

title = 'GISMO'; // $this->content_type = BLOCK_TYPE_LIST; //$this->course = $course; $this->version = 2005091000; } function specialization(){ $this->course = get_record('course','id',$this->instance->pageid); } function get_content() { global $USER, $CFG, $THEME; if($this->content !== NULL) { return $this->content; } $this->content = New object; $this->content->items = array(); $this->content->icons = array(); $this->content->footer = ''; if (isguest()) { return $this->content; } if ($this->course->id!=1) { if (isteacher($this->course->id)) { $this->content->items[]=''.'Students Tracking...'; $this->content->icons[]=' gismo.gif'; $this->content->items[]='Domain Configuration'; $this->content->icons[]=' domain.gif'; } } else{ return $this->content; } return $this->content; } } ?>

Block gismo: block_gismo not implemented
 
Could anyone please help me on this.
 
Thanks,
 
Ollie

There is a small error in the block_gismo.php file.
the red text (PHP) was left out of line 15

<?PHP
class block_gismo extends block_list {...


this fixed it for me

Hi,

I've had this problem also using Moodle 1.5.4. Tracked it to Gismo using short php tags. There are two ways to overcome this:

1. Short-term: edit php.ini and set the flag short_open_tag = On (not recommended - but a time saver).

2. Long-term: take Mark's suggestion and do a find/replace in these files: block_gismo.php, setupdomain.php, applet.php, credits.php, help.php and replace <? with <?php.

There may be some other files that need changing that I've not yet come across!

... and attached is a zip file containing the latest gismo-1.0rc1 with the relevant php files and all the short tags removed. It's been tested OK with Moodle 1.5.4 and 1.6 so I'm emailing Christian Milani with these suggestions.

//Start rant...

Gismo is one of those blocks that adds a wow! factor to moodle. From the teaching perspective, it supplements the moodle logs and allows an instant overview of student progress through activities and of their achievement or under-achievement. Why, oh why, is this not available as a download through moodle.org?!

//End rant

Do you also have the setupdomain feature working under 1.6?  The link still just gives me Page cannot be displayed... DOH

I don't get this error, but instead there looks like there is a parameter passing bug in fetching the $id variable. Here's my fixed setupdomain.php from Moodle 1.6 blocks/gismo directory.

Can you try out and report back.

Re: Gizmo Installation Problem

by Ken Wilson -
Peter -- The Java access controller is saying that it cannot access to the applet LoadMainGui, so there is an io exception. This looks like a permissions problem. Check these:
- get the latest version of the java client for your machine
- if IIS is running on the local computer, set it to anonymous authentication (not NTLM)
- your web server should be able to execute scripts in your gismo folder. When the browser requests the java program it downloads it from the client and it is then transferred into memory and executed by the Java Virtual Machine. If there are no execute permissions then this will fail.

Re: Gizmo Installation Problem

I was having the same problem, then I read the README.txt. Did you run the export_data.php?

It still doesn't quite work for me, the applet loads but has no data. this seems to be due to a reorganization of Moodle's data tables in version 1.7, renaming "user" to "mdl_user" and "user_students" as I haven't figured out what yet.

Hey Ken,

Sorry it took me so long to reply, but I was forced to get this thing live a bit before I thought.  Tried out the file and can actually get to the setup domain settings now, although I can't add a concept.  I'll give it another look in the coming week to see if I can find the problem. Thanks for your efforts!
