PHP - Crot Anti-plagiarism Resubmit And Check If Date Has Modified.
Hello guys, i have a problem that i am trying to solve myself for the entire past week. I am not a php programmer and i wish you can help me.
There is a russian project called Crot Anti-Plagiarism, it is a open source moodle plugin. I started to use it and it is a really nice feature. The problem is that there are quite few people that are developing it and new features are coming once a year... I see a big "hole" in this project (at least for me) : The plugin checks for plagiarism in the file that you submit only once, if a student resubmits the file it doesn't see that and you need to start the plugin's test again for all the files which is time consuming if you have a lot of submitted files to check. I would like to add a function that will check if a file changed his modified date , if yes - mark for checking, if no - skip the checking. I already added a similar function that checks if the name has changed, but it seems harder to check it by uploaded time(modified time). Things i have already done: I added a new column "assignment_submissions_timemodified" in database. I added a new function that records the "time modified" of the file in the database. But i can't add and i cannot make the comparison between the date of the first time the file submitted versus the date of the second time the same file was resubmitted. Alright no more bullsh**t here is the code: (there are 3 comments that shows what i've changed, starting with //my job...) Thanks a lot! Code: [Select] $apath= $CFG->dataroot."/$assignment->course/moddata/assignment/$asubmission->assignment/$asubmission->userid"; $timemodified= filemtime($apath); //my job... it checks the file's modified time. $files = scandir($apath, 1); if (! $unprocessedsubm = get_record("crot_submissions", "submissionid", $asubmission->id, "crot_submission_file_name", $files[0], "assignment_submissions_timemodified", $timemodified)) //my job...now i guess here is the problem ( "assignment_submissions_timemodified", $timemodified) { echo "$timemodified"; echo "$unprocessedsubm"; print_r($unprocessedsubm); echo "\nsubmission $asubmission->id was not processed yet. start processing now ... \n" ; $atime = microtime(); $atime = explode(" ",$atime); $atime = $atime[1] + $atime[0]; $astarttime = $atime; if(!count($files))break; //TODO we should verify if filename changed //TODO add loop on the documents folder as well as loop for unzipping $apath = $apath."/$files[0]"; // call tokenizer to get plain text and store it in crot_submissions $atext = tokenizer ($apath); // update the crot_submissions table // delete if exists delete_records("crot_submissions", "submissionid", $asubmission->id); // insert the new record $record->submissionid=$asubmission->id; $record->updated = time(); $record->crot_submission_file_name = $files[0]; $record->assignment_submissions_timemodified = $timemodified; //this is my job.... it is recording the date as it has to. $submid = insert_record("crot_submissions", $record); // insert into documents $docrecord->crot_submission_id = $submid; Also i have attached the whole file crot_crone.php.

The reason why I ask for IP check is I wan't to use
$_SERVER["HTTP_X_MXIT_USERID_R"];in the place of the Ip since it give a unique name via the platform I want to implement it. Edited by cobusbo, 14 January 2015 - 01:49 PM. I have a small script on the bottom of all my pages on my site which list the date and time the page was modified. I want to make the script an include and just put that on the page, but as it is now scripted that won't work since you have to change the page name for every page.

Any body here who can help me to make a plagiarism checker in php? that can accurately get the site of the content that is copied from internet. thanks in advance. godbless.
Currently I have an Input field for a "Written On Date". What is the best way to make sure a valid date is entered? Should I use Regular Expressions? Some PHP Date-Checking Function? Or switch to Drop-Down Lists to better control the selectable values? (Which won't catch things like June 31?!) Debbie What is the best way to check for a Date in a Form? I see there is a CheckDate() function, but how does that know what format the Date is in? Should I use a Regular Expression? My Form Field is just a Text Box... Thanks, Debbie Hi I made a simple chat script with pagination in MySQL (yes I know I should change to MySQLi) but just bare with me please My script is working fine when I post messages, but I have a problem.. Each time I refresh my page my previous message gets reposted again. Is there maybe a way I can fix this problem?

check date is in format of Y-m-d I am trying to check if a credit card has expired. My criterion is whether or not the date submitted is prior to this month if the year matches 2011. Code: [Select] // Check for Expired Card. if (($expYear = date('Y')) && ($expMonth < date('M'))){ $errors['expDate'] = 'Expiration Date cannot be in the past.'; } Why is this not working? I chose March 2011 and it fails. In fact, it fails for any date?! Debbie Hi all, How can I check in PHP if this date has already passed in the following format: 2012-12-12 This topic has been moved to Ajax Help. http://www.phpfreaks.com/forums/index.php?topic=313543.0 I have two text fields in a form. Both accepts dates. I'd like to check whether the second date provided is exactly one year in the future from the first provided date.
I can easily do this in PHP but since I need to do the check once the user leaves the second field, I have to resort to JavaScript, using onblur or something.
There are two issues I have.
1. Make sure that the strings provided are indeed dates (I would use strtodate() in PHP for this)
2. Regardless of month provided, making sure that the second date is exactly a year in the future of the already provided year
I've only captured the values and passed them to Date(). However, it can only handle european style, and if I enter 1981-06-16, the value returned is Jun 15 1981 17:00:00 which is obviously wrong.
Here is the simple broken code I have
var text1 = document.getElementById("text1");
var start_date = new Date(text1.value);
var text2 = document.getElementById("text2");
var end_date = new Date(text2.value);
alert(start_date);
I need some guidance.
Using MVC, the controller does some logic, gets data from the model, and the view presents the content.
Where should the reverse be performed?
For instance, I have an edit page which is pre-populated with values from the model, and the view changes 1000 to $1,000, 0.4 to 40%, and 2014-10-09 09:31:41 to 10/09/2014 09:31:41 AM.
Now I need to save the values, and must convert them back to their original format before doing so. Should this functionality be performed in the controller, model, or view?
Thanks
