Anyone knows some jquery plugin to count how many times a file (pdf, in my case) is download from your server??
you can simply use the google analytics javascript API with an onclick event
Then you can have beautiful charts for your downloads. see here for an example case : http://think2loud.com/use-jquery-with-google-analytics-to-track-clicks-on-outgoing-links-from-your-site/
You can create script download.php that count your download links.
<?php
// connect to database
if (isset($_GET['file'])) {
$file = mysql_real_escape_string($_GET['file']);
$query = "insert into downloads VALUES('$file', 1) on duplicate key " .
"update count = count + 1;, count+1)";
mysql_query($query);
}
?>
downloads table is:
create table downloads(file VARCHAR(255) primary key, count integer default 1)
and in jQuery
$('a.download').click(function() {
//empty function don't care what I get.
$.get('download.php', {file: $(this).attr('href')}, function() {});
});
it call download.php script with href attribute on every link that have download class
UPDATE I forget to add return false because in code above it call ajax and then abort it.
$('a.download').click(function() {
var link = $(this).attr('href');
$.get('download.php', {file: link}, function() {
// change url to link when ajax is finished
window.location = link;
});
// prevent following the link
return false;
});
You can also add code that prevent multiply clicks because there will be delay between ajax call finish and changing url to link of a element (user may click few times because it will not folow the link) and you can add CTRL+click because it open link in other window (you can return true in this case).
You can use jQuery to determine how many times a single user clicks on a given link on a given fully-rendered page, and use that value to update a database table of download clicks through AJAX, but jQuery doesn't have any direct insight into your server-side data as relates to the total number of downloads, you would have to be updating a database with that data and displaying it from there. you could use jQuery to watch and see if that value changes (on a timer maybe) and update your page accordingly, butthat still requires a AJAX call to a database lookup.
jQuery is a library for Javascript with is a client-side language and acts on the page once it is downloaded and running on the client's machine and as such is not the place for server-side logic and lookups except in the cases where AJAX is warranted and needed.
This is impossible. jQuery code runs in a user's browser, not on a server. To count downloads you'll need server-side code.
jQuery alone won't be able to do that.
You would have to keep track on the server each time the file is requested.
Is there anyway to modify the above script to allow only 1 download per user in a set period of time based on the date they joined the site, i.e. the user can only download the file once per year starting from the day they joined the site?
I'm using Wordpress to run my site.
Thanks

I tried to find it on StackOverflow and also tried to google it, but could not find any relevant answer.
I want to send monthly reports to the user of Laravel application with a PDF that contain a graph/chart.
This is what that is already done
Created a route, lets say
Route::get('/print/', 'PrintController#report');
In printController created a report function that is getting all the necessary data from the DB and returning a view with user data
return view::make('monthly_report', $user_data);
In monthly_report view, get all the user data, show the view and create a chart with the data. The chart is created with Charts.js. it is in a canvas.
Send the generated chart as image to the server with Ajax. For example
var canvas = document.getElementById("myChart"), // Get your canvas
imgdata = canvas.toDataURL();
file_name = "<?php echo $chart_file_name; ?>"; //created with userId and date
//send it to server
$.ajax({
method: "POST",
url: "save",
data: {
data: imgdata,
file_name: file_name,
_token: token,
}
});
Created a save route
Route::post('print/save', 'PrintController#saveChart');
In print controller, saveChart function, save the chart
$data = base64_decode($data);
//save chart on server
file_put_contents("Charts/".$fileName, $data);
Then create a PDF report by using another view monthly_report2, that is also in saveChart function. The view monthly_report2 does not use any JavaScript and use the chart image that was generated by monthly_report, in number 6.
$pdf = \PDF::loadView('monthly_report2', $cll_data);
file_put_contents("reports/".$pdf_name, $pdf->output());
It save the generated PDF on server. So far so good.
To send these PDF reports to the users by e-mail, I will created a schedule/crone job that will be run on a specific date, monthly and will send the e-mails with PDF reports as attachments.
I skip some details for clarity, please ask, if you need more information.
Thank you for reading so far, now I have two questions
The way I am doing is good or it can be improve?
We want all this process automatically (generating reports and sending by email). To generate the PDF's, monthly_report view must be loaded? so that it generate the Chart and send it to the server. Can we schedule it also, so that it generate the pdf reports automatically?, If no, is there any other way to do it?
Kind of a big question, but I'll try to answer
I think it's good. I'm not a big fan of using JavaScript to create charts, but that's me. You obviously know what you're doing and PDF generation is in my experience a "If it works, please don't break it" functionality.
I think this might be more difficult. Since you're using JavaScript to create charts, you need some kind of engine (NodeJS comes to mind) to parse the JavaScript and actually create your charts without opening a browser and doing it manually. (This is why I don't like using JavaScript to create charts). You could take a look at tutorials like this one to get an idea of how to render your charts serverside.
After that, you can take a look at the Laravel task scheduler (provided you're on Laravel 5, a community package exists for Laravel 4). You can schedule existing and custom-made commands to be executed. In pseudo-code, a PDF generation command could look like this:
public function createAndSendCharts() {
// 1. Get necessary user data
// 2. Create your charts
// 3. Save your charts
// 4. Create email with charts
// 5. Send your email
}
You could then add that function to your Task Scheduler
$schedule->command('send:charts')
->monthly();
Hope this was of some help. All in all, you're doing fine, but the choice for ChartJS has some consequences if you want to automate the whole process. Nothing really special, tons of tutorials exist for this situation :)
I want to hide posts in the feed that have a #joined hashtag. I tried to create a GreaseMonkey script with jQuery in the past, but it couldn't detect any posts that have the #joined text.
Am I using the wrong library? A starting point, or an existing library/plug-in would be helpful.
OFF-TOPIC: At the moment, Yammer does not have any feature to hide posts with a specific hashtag, although it has a feature to follow a hashtag.
I know that this is a pretty old question but I too was trying to create a Chrome based Add-on that hides these #joined posts (or any post with a specific hashtag). I came across this blog https://you.stonybrook.edu/thebaron/2014/10/06/hiding-joined-yammer-posts-in-chrome/ where the author of the post has shared his work (https://gist.github.com/thicknrich/e4cc2871462a6850fe8c). This is a simple javascript and does the job.
//Script from https://gist.github.com/thicknrich/e4cc2871462a6850fe8c
//load jQuery based on this SO Post:
//http://stackoverflow.com/questions/2246901/how-can-i-use-jquery-in-greasemonkey-scripts-in-google-chrome
// a function that loads jQuery and calls a callback function when jQuery has finished loading
function addJQuery(callback) {
var script = document.createElement("script");
script.setAttribute("src", "//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js");
script.addEventListener('load', function() {
var script = document.createElement("script");
script.textContent = "window.jQ=jQuery.noConflict(true);(" + callback.toString() + ")();";
document.body.appendChild(script);
}, false);
document.body.appendChild(script);
}
// the guts of this userscript
function main() {
// Note, jQ replaces $ to avoid conflicts.
setInterval(function() {
//if a item thread contains #joined, hide it
//check every 5 second.
jQ('.yj-thread-list-item:contains("#joined")').css("display", "none");
}, 5000);
}
// load jQuery and execute the main function
addJQuery(main);
You can find all joined messages with the following endpoint, based upon the #joined topic:
GET https://www.yammer.com/api/v1/messages/about_topic/[:id].json
But you can only delete messsages that you own:
DELETE https://www.yammer.com/api/v1/messages/[:id]
Source: https://developer.yammer.com/restapi/
Note that this is a conscious decision by the product team, although joined messages can get spammy when a network becomes viral, it is a great opportunity to engage users right away once they join. It makes them feel welcome. As a community manager, I'd encourage you to welcome that user in and also encourage other yammer champions to welcome these users also. As a side effect, it also encourages people to follow the groups they are interested in and use the Top or Following feeds instead of the all (firehose) feed which has all these joined messages.
Just want to note that the statement in a reply here "But you can only delete messsages that you own" is not entirely correct it is possible to delete message that do not belong to you if you are a network admin. I just ran a little experiment after reading this post and deleting #joined messages that don't belong to me worked just fine.
I have a results page and I am trying to work out how to auto update the page when an external database field is updated. I have seen quite a few examples but they seem to relate to PHP. I have a test that calls various APIs that can take up to an hour to complete. Once the test has completed, it will enter a success or failed message in a database field.
I already have my results page being rendered by django using template tags. I have a table and I have the field I would like to update. There are multiple fields that need update which correspond to each API test.
I have seen this site.. is this the kind of stuff to use? http://www.dajaxproject.com/ Is this an easy task to do? Does anyone have any ideas on how to do this?
Sorry but I don't know where to start on this one.
Cheers - Oli
I decided not to be so bold and just use the old classic page update for this purpose using javascript..
window.onload = setupRefresh;
function setupRefresh() {
setTimeout("refreshPage();", 30000); // milliseconds
}
function refreshPage() {
window.location = location.href;
}
Still open for options however I'm rather inexperienced in django and maybe this was too much to bite off too quickly..
I want to load single posts into an index page using Ajax for a WPML based site that I'm working on. Not sure what I'm missing but there seems to be a catch when using multiple languages and fetching the correct posts.
Here's the code I wrote -
function loadProject(reference) {
console.log(window.location.origin + '/references/' + reference);
// Displays "http://mysite.com/references/example-post/", which exists
$('#content').load(window.location.origin + '/references/' + reference, function() {
console.log('Load was performed.');
});
}
I don't reach the JS log after load() but I don't receive any error message either (e.g. "File not found").
"References" is a custom post type that I've created using the Types plugin, and has a file of it's own called single-references.php. I'm not entirely sure how CPTs work with WPML, and that's probably where the problem lies. I have two languages, Swedish and English, and the CPT only has one slug for its kind ("references").
[Solved]
Used the .get() method instead to retrieve the post and now it works.
Well, no console error, no network query :
it is not a WPML issue
did you check #content really exists ?
In chrome dev tool, go to Network, and trigger your function. You'll see what you receive.
How to update a site with some other site contents that is getting refreshed often (may be twice in a minute)?
What you're doing is called scraping a website. Try googling on that. Pay particular attention to the laws around it. If you're benefiting the company you're scraping, they'll probably help you; if you're not, they'll probably sue you.
$.load() is your friend. The following JQuery-function call will replace the current value of element (e.g. div) with the id "result" with the content of page "ajax/test.html".
$('#result').load('ajax/test.html');
or with an additional success handler:
$('#result').load('ajax/test.html', function() {
alert('Load was performed.');
});
if you would like to call one of these function every n seconds, use the following code:
setInterval(function() {
// wrap one of the above calls
}, <n>000);
edit:
for a cross-domain-solution, you can write a proxy page on your site which, upon call, loads the content of the 'other site' and echoes it.
