Hi,

Please check for a local "tmp" folder in either koolreport/export or where your report is. If it exists please try this simple comment to see if it works or returns an error:

<?php
    file_put_contents($pathToLocalTmp, "Hello world");
?>

Hi,

Looks like the "Could not save content to temporary folder" error is no longer there.

Regarding blank pdf issue, which http server were you using? If it's a PHP's built-in server or Laravel's the Export package won't work correctly because Export uses PhantomJS which is knowed to not work perfectly with some dev servers like the PHP's one. If it's the case with yours, please try Apache, nginxx, etc.

Please create a file called "MyReportPdf.view.php" with only text like "Hello world". Then use this export command:

$report->export("MyReportPdf")
...

Let us know the result. Thanks!

In your local tmp directory there should be a number of files with .tmp and .pdf extensions. Please open the latest .tmp file with your text editor and see if it has any content?

Please try the follow commands and let us know the result:

<?php
    ini_set('display_errors', '1');
    ini_set('display_startup_errors', '1');
    error_reporting(E_ALL);
    file_put_contents($pathToLocalTmp . "/test.txt", "Hello world"); 

Hi,

Please open the file koolreport/export/Handler.php and look for this line:

    if (file_put_contents($source, $content)) {

Please put the following commands just before it:

    echo "file path = $source<br>";
    echo "content = " . htmlentities($content); 
    if (file_put_contents($source, $content)) {

Then click your export button to see if any content is outputted to the screen. If there's one please check to see if there's any file with the outputted file path. Let us know the result. Thanks!

If there's file path and content please check to see if there's any file with the outputted file path.

We are taking step by step checks. I am asking you if the $source file path exists and if there's any content in it?

It's strange that the .tmp file couldn't be found but now exception wasn't thrown. Please open the file koolreport/export/Handler.php and replace the following code:

        if (file_put_contents($source, $content)) {
            return $source;
        } else {
            throw new \Exception("Could not save content to temporary folder");
            return false;
        }

with this:

        if (file_put_contents($source, $content)) {            
            echo "Content is saved to $source";
        } else {
            echo "There's problem saving content to $source";
            throw new \Exception("Could not save content to temporary folder");
        }
        exit;

Then run export again and let us know the result. Thanks!

Please check content of the file C:\Users\myuser\AppData\Local\Temp/5f7bf0bbccaf51.tmp

The content looks good. Please open Handler.php and look for this line:

        $result = shell_exec($command);

and put this just before:

        echo "command=$command<br>"; exit;
        $result = shell_exec($command);

Run export to see the outputted command. Then copy and paste the command to your command line/terminal to see the result. If there's no error message there should be a pdf file in the tmp folder. If there's any error let us know.

Please make sure you downloaded the correct PhantomJS binary file to this path: E:\xampp\htdocs\cs\vendor\koolreport\export/bin/phantomjs.exe from this link:

https://phantomjs.org/download.html

Then try to run this standard example of PhantomJS:

https://phantomjs.org/screen-capture.html

Let us know the result. Thanks!

Please use this path in your hello.js example: E:\xampp\htdocs\cs\vendor\koolreport\export/bin/phantomjs.exe

If you can run PhantomJS example fine, please repeat this step:

https://www.koolreport.com/forum/topics/1639#p8845

Please create a file called github.js in your tmp folder with this content:

var page = require('webpage').create();
page.open('http://github.com/', function() {
  page.render('github.png');
  phantom.exit();
});

Then open the command line/terminal and run the following command (remember to change path/to/tmp with your path):

E:\xampp\htdocs\cs\vendor\koolreport\export/bin/phantomjs.exe path/to/tmp/github.js

Let us know the result and post your exact command for us. Thanks!

Thank you Mukesh for chatting with us via Messenger. All are working now. The root cause is that Export package will not work with PHP Built-In Webserver. This built-in webserver is normally started with command php -S or php artisan serve in Laravel. The Export package will work with popular/production webserver like Apache or Nginx. For further details, please look at our post here.

You are welcome :)
