I have started using the Dhtmlx Scheduler a few days ago, i went to the docs to see how to create a simple connection and load some data but i keep getting this: { "data":[]} has the response of my .php file. My code is:
<?php
include('connector-php/codebase/scheduler_connector.php');
$pdo=mysqli_connect("localhost","root","pass","hotel");
$scheduler = new JSONSchedulerConnector($pdo);
$scheduler->render_table("TipoQuarto","idTipoQuarto","Nome,Preco");
echo scheduler;
?>
For now i´m just working on the .php file to see if the connector can find my data, and i know there is data there. My database has several tables, so i´m selecting the TipoQuarto, then the id of the field(idTipoQuarto) and then the fields i need, but it´s not displaying anything. Can anyone help me?
Regards.
For MySQLi server side code will look like next
require("connector/scheduler_connector.php");
require("connector/db_mysqli.php");
$mysqli =mysqli_connect("localhost","root","pass","hotel");
$scheduler = new JSONSchedulerConnector($mysqli, "MySQLi");
$scheduler->render_table("TipoQuarto","idTipoQuarto","Nome,Preco");
you need to include db_mysqli.php
second parameter of constructor must be "MySQLi"
Also, in render table, third paremeter mast include start date, end date and text fields. You are providing only two of them.

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 have several Birt Reports that I am trying to set up to run on a cron job that will email pdfs of the reports every morning. Everything is working fine as far as the generation and emailing goes; the only issue I am stuck with is this: if there is nothing to report, a pdf with just the report title is generated and emailed (a blank report, basically). I'd like to stop this report from being generated at all, so i can skip the emailing, if the pdf file does not exist.
I have been all over Google for two days now, and the closest I can find is this: http://www.eclipse.org/forums/index.php/t/458779/ in which someone was trying to solve a similar problem and received a push in the right direction, but not a complete solution.
It appears as if this can be done during the beforerender script... but how?
I know I need to:
set a persistent global variable in the oncreate if there is indeed data to report.
get the persistent global variable in the beforerender script.
send the magic don't generate report command.
I'm doing all of generating and emailing from a php script, not Java, so I can't send commands like IEngineTask.cancel() (or can I???)
Yes, I know I can make a row in the report that says "No data to report", but that's not what my users want.
And yes, I could query the database outside of the report to determine if there is valid data to report or not, but i'd prefer not to.
And maybe I could even open and read the pdf, programmatically to see if there is anything there, but that sounds like more of a hassle than it's worth...
So, how do I do this?
Thanks.
My answer is a little bit late, but I'm doing it like this in a framework that is working for hundreds of reports, probably it could be simplified for a single report:
Note that all the code is written from memory (not copied from our framework), so maybe it contains some errors.
Add an external Javascript file myframework.js to your report.
In this file, define an object myframework like this:
if (myframework == undefined) {
myframework = {
dataFound: false,
afterReport: function() {
// Write it to the appContext.
// Using Java, you could read it after the
// runAndRenderTask is done.
reportContext.getAppContext().put("dataFound", this.dataFound);
// But since you probably cannot the context
// (don't like coding Java?), the report has to
// tell it to he world some other way...
var txt = "dataFound=" + (dataFound? "true": "false");
var fw = new java.io.FileWriter("c:\\reportcontext.out");
fw.write(txt);
fw.close();
}
};
}
Add the JS file to your report's resources.
In your report, at a place where you decide that the report has found something (e.g. typically in a data set's onFetch event), tell the framework so by calling
myframework.dataFound = true;
In the reports's afterFactory or afterRender event, call
myframework.afterReport();
Then your report should create an output file c:\reportcontext.out which contains the information you need.
This is not working as we discussed previously, for some reason and I have done is create some $vars for the uploaded file.
Code available here (Pastebin).
But never actually inserts anything
When doing a var_dump($csv_row) i get: bool(false)
var_dump($fh) shows: resource(89) of type (stream)
var_dump($insert_str) shows all 1700 records from the csv file (obviously too big to post on here)
So I’m guessing the while statement or the whole from if statement is wrong somewhere. Really really would appreciate some help on this, I need to get it working by tomorrow (monday)
You seem to be using the codeigniter database library wrong. I can see a
$this->db->set($insert_str);
but no $this->db->insert() to be found. The set() method only useful with an update() or insert() following it, See the docs, search for $this->db->set().
You either want to use the $this->db->insert_batch() (on the same doc page, unfortunately no direct links for sections) form and build up an array of arrays with your records (so you won't have to create a long sql string either).
Or you can use the $this->db->query() and just feed the $insert_str to it where you now call $this->db->set().
According to your question:
var_dump($insert_str) shows all 1700 records from the csv file
So i would rule out the possibility of the while loop or the if not working.
Put this code at the top of the controller or before reading csv file
ini_set('auto_detect_line_endings', true);
Check if this will work for you
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 am new to vb6. I am working to create the invoice generation application. I am using data report to show the generated invoice.
The step by step working of process is:
Entering the data in to Invoice and ItemsInvoice tables.
Then getting the maxId using (Adodc) from the data base to show the last generated Invoice.
Then passing the max Id as parameter to the data report which is showing the invoice according to the invoice id.
It is working fine when I first time generate invoice. Now for 2nd invoice without closing application I am getting a blank data report. For data report I am using dataenvironment.
I am guessing the reason the data report is blank is because there was no record for that Id, but actually the record is inserting in the database.
What is going wrong?
I'm not sure how your data set is getting configured, but it sounds like you have a single record in the data and aren't reloading it properly. If your report is manually moving through the recordset and only showing info based on the ID parameter you are passing it and then using the same recordset for the second report, you probably just need to MoveFirst on the recordset to put it back at the beginning.
Load the data environment and refresh the data report.
I am also generating report in the similar fashion. I faced this problem. Here's the solution
Load DataEnvironment1
With DataEnvironment1
'Command1 is the command added to data environment where you fire query or
'set it to point to a table
If .rsCommand1.State <> 0 Then .rsCommand1.Close
.Command1 maxid 'parameter you pass to the recordset
End With
DataReport1.Refresh
DataReport1.Show
Thats it!
You are done. I m sure it will work. Do tell me if it doesn't.
I don't know if the answer will still bother you, but if someone else have the same problem here is a example of how the problem works:
Imagine that there is a gate and a guard looking who is entering, when the first person (the first invoice) comes, the guard registers him, opens the gate (This is the event "Load DataEnvironmet") and then lets the guy pass. The guard believes that no one else would come and lets the door open (the instruction believes that the DataEnvironment ends and the value EOF becomes True), but when the second guy comes (the second invoice) the guard can't ask him who is (has, again, the value and lets it pass without registering him (this is the reason why the second invoice, and subsequent in while invoice would come blank). The solution is to close the gate ("Unload DataEnvironment") after a guy passes (After showing the data report).
The solution is the code given from Sangita above, but just before ending the sub you need to unload the DataEnvironment you were working on.
For me, it works. Sorry if the answer is not what you were looking for (and also if someone else can't understand what I'm writing, my English isn't very good). Just in case I will write the code with the solution
Load DataEnvironment1
With DataEnvironment1
If .rsCommand1.State <> 0 Then
.rsCommand1.Close
End If
.Command1 Value(ID)
End With
DataReport1.Refresh
DataReport1.Show
Unload DataEnvironment1
Try a refresh method like data1.recordset.requery or
Data1.refresh. This should work if you use data controls.
