function fnEncrypt issue in function.php

[Cybertel777]

Hello,

I get these errormessages after having installed latest version of sturesy server (server-master.zip):

Warning: mcrypt_encrypt(): Key of size 0 not supported by this algorithm. Only keys of sizes 16, 24 or 32 supported in /home4/cybertel/public_html/qmaster/functions.php on line 147

Warning: Cannot modify header information - headers already sent by (output started at /home4/cybertel/public_html/qmaster/functions.php:147) in /home4/cybertel/public_html/qmaster/functions.php on line 59

Do you have any idea how to overcome it?

Thanks for feedback

Hello, In fact, I also realized, that none of the existing StuReSy versions is compliant with the php config of my webserver.

After facing each error message and replacing the concerned code with a corresponding one from earlier StuReSy versions I finally ended up with a full working "update" (I joint the "patchwork" in a zip file).

I really like your app and and didn't want to give it up. I think it is a kind of model for me, an example of what a well designed and well functioning software should be. I am convinced that with only some minor changes, enhancements and upgrades this "little" StuReSy could easily become a masterpiece, a kind of milestone in the area of elearning app development and change from a mere student responsive system to an integrated ecourseware management system.

Let me explain what I mean:

I discovered only recently the option in the StuReSy Client application to add html code with a wyswyg html editor. This is amazing because it allows to use the StuReSy question editor as a kind of course or lecture presentation tool without loosing its actual functionality.

Teachers could such use it not only to set up some question and answer sessions to complete their lecture, but could also easily use it to present their whole course or lecture content.

For example:

After an introduction Chapter 1 opens with a lecture video, available on a dedicated Youtube channel and embedded in an iframe. The video presentation page is followed by a question and answer session to evaluate the students comprehension before chapter 2 will take over and so on until the end and the conclusion of the course.

The next step could be to make the whole lecture content avalable online and on demand. How?

Simply by feeding a mysql database with the course content that is already saved in xml format by your app. Once the table structure of the database is lined up with the xml structure it is a snap to import new lectures (with question/answer) content by using the already available xml files of a teacher.

And last not least it would be interesting to add some javascript to the online php dbase interface so that students who want to prepare or review a lecture of their choice can evaluate their knowledge by doing some quizzwork and auto evaluation.

Once the 3 three basic app modules linked together in the right way we could end up with a "big data" fueled elearning platform able to structure, contain and deliver the entire courseprogram of a university at the condition that all essential content media a stored on other places online and linked to the html content and presentation field of the database.

So, that is in short the potential I see in StuReSy. Please let me know what you think about it and if such a perspective is worth for you to be developed further.

Best regards

this seems to be a problem with php 5.6. the last ive tested was with php 5.5

also i understand your enthusiasm for making sturesy better and greater, but currently it lacks the manpower to make any of these changes

Thanks a lot for your quick response.

You certainly know that a way to realize things is always found if there is a will, a desire strong enough to find it. (Wo ein Wille ist, ist auch ein Weg). I totally understand that at the first glance manpower is lacking to pursue future development of StuReSy in the direction I mentioned before, may be too for the reason that there is no evident commercial interest in doing so.

But if we take it just from an educational point of view, students and even teachers would be glad to profit from an elearning plateform that allows them to prepare and even to review a whole study program. So why wouldn't it be possible to engage informatic students to work on the project in the frame of their study cursus with the agreement and the active support of their staff?

In anyway even if you think it might not be possible under the/your actual circumstances, I am ready to try my best to develop the missing modules, especially the online database with presentation and quiz functionality.

I also wanted to tell you, that the wyswyg html editor of StuResy lacks some basic functionality. I tried to introduce some links, but they don't work in presentation/voting mode, and of course, video and audio integration embeded by iframes and even simple hyperlinks don't work either.

Never the less you did a very good job in programming this app and I will try to do my best to extend its possibilities, even as a "lonely man" without great programming knowledge and software power. :-)

It was nice to meet you, and I hope you keep up doing the good work you are able to do

with kind regards
