The SWF is located on a web server. I am calling the function using this code in AS3...
myPDF.save(Method.REMOTE, "http://www.example.com/generator/createpdf.php",
Download.ATTACHMENT, "line.pdf");
Here is my PHP script located on the server...
$method = $_GET['method'];
$name = $_GET['name'];
if ( isset ( $GLOBALS["HTTP_RAW_POST_DATA"] )) {
// get bytearray
$pdf = $GLOBALS["HTTP_RAW_POST_DATA"];
// add headers for download dialog-box
header('Content-Type: application/pdf');
header('Content-Length: '.strlen($pdf));
header('Content-disposition:'.$method.'; filename="'.$name.'"');
echo $pdf;
} else echo 'An error occured.';
It used to work, but stopped a while back. Any help would be greatly appreciated.
1) This stopped working for me as well, until I added the following -
if(!$HTTP_RAW_POST_DATA){
$HTTP_RAW_POST_DATA = file_get_contents(‘php://input’);
}
2) I also patched /src/org/alivepdf/pdf/PDF.as::save() per this post enter link description here

Everyone.
This question maybe duplicated with Using PhantomJs, how to get and handle the new page?.
But there was not exact answer.
My question is as follows.
The pages what I want to scrape 3 pages.
1st Page : input unique id , click next.
if valid id => go to 2nd page.
2nd Page : click link(contains id)
3rd Page : download Pdf File.
So my aim is to download pdf file from unique id automatically.
Then the main point is how to handle page transition in Phantom PHP?
My test Code is as:
// Use the composer autoloader.
require_once 'vendor/autoload.php';
// Setup mink drivers.
$goutteDriver = new \Behat\Mink\Driver\GoutteDriver();
$phantomjsDriver = new \Behat\Mink\Driver\Selenium2Driver('phantomJS');
// Setup mink sessions.
$goutteSession = new \Behat\Mink\Session($goutteDriver);
$phantomjsSession = new \Behat\Mink\Session($phantomjsDriver);
// Setup mink session manager.
$mink = new \Behat\Mink\Mink();
// Register sessions.
$mink->registerSession('goutte', $goutteSession);
$mink->registerSession('phantomjs', $phantomjsSession);
// Set Goutte as the default session.
$mink->setDefaultSessionName('phantomjs');
// Visit mink website with phantomjs driver.
$mink->getSession('phantomjs')->visit('https://testurl.com');
// Get the default goutte session.
$session = $mink->getSession('phantomjs');
// Get the page document.
$page = $session->getPage();
echo $session->getCurrentUrl(), PHP_EOL;
// $page->find('css', '#guides')->clickLink("Drivers");
// echo $session->getCurrentUrl(), PHP_EOL;
// Output the installation instructions from the page.
$input = $page->find('css', '#id');
$input->setValue("1234567890");
echo $input->getValue(), PHP_EOL;
$page->find('css', '#validar')->Click();
echo $page->find('css', '#validar')->getValue(), PHP_EOL;
$session->executeScript('document.getElementById("validar").click()');
//$session->reload();
sleep(5);
// $mink->getSession('phantomjs')->visit('https://testurl.com/next');
$page = $session->getPage();
echo $session->getCurrentUrl(), PHP_EOL;
sleep(5);
$mink->getSession('phantomjs')->visit('https://testurl.com/next2?id=1234567890');
$page = $session->getPage();
echo $session->getCurrentUrl(), PHP_EOL;
// Stop browser sessions.
$mink->stopSessions();
So

How to download pdf file properly?
I am trying to connect to my own self created second database using wordpress.
What i am trying to achieve is to extract data from my own database(not wordpress database) on my static wordpress front page.
I use php_everywhere plug in in order for me to write php code in blog post and pages.
I use the following code:
<?php
$servername = "localhost";
$username = "thomas";
$password = "password";
$dbname = "thomas";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * from number";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "id: " . $row["id"]. " - Name: " . $row["firstname"]. " " . $row["lastname"]. "<br>";
}
} else {
echo "0 results";
}
$conn->close();
?>
However i got an error unexpected '"localhost"' (T_CONSTANT_ENCAPSED_STRING).
Not sure why.
See https://stackoverflow.com/search?q=T_CONSTANT_ENCAPSED_STRING
1) When using that plugin, be sure you've used straight quotes and backspace around the php to remove invisible control characters. And be sure the plugin doesn't have limitations on what it can do and ignores paragraph returns in the editor.
2) You're much better off using a page template in your theme and running PHP in a .php file and not in the post/page editor with a plugin. See Page Templates | Theme Developer Handbook | WordPress Developer Resources. Make a page template, add the calls to header, etc., and then work with your PHP in the file itself. Select the page template in the page editor of the page you're publishing in WordPress.
You can create new object for new database connection and use that object to do any operation for external database
$mydb = new wpdb('thomas','password','thomas','localhost');
$rows = $mydb->get_results("select Name from my_table");
You must have to use $mydb in place of $wpdb
Wordpres provide a way to connect the other db.
$mydb = new wpdb('thomas','password','thomas','localhost');
$rows = $mydb->get_results("select Name from number");
foreach ($rows as $row) :
echo "id: " . $row->id. " - Name: " . $row->firstname. " " . $row->lastname. "<br>";
endforeach;
I want to display a download link inside a WordPress widget. The file to be downloaded is located in the download subfolder of the site root, so that it can be uploaded via FTP. The name of the file and the text to be displayed for the download link shall be stored in a simple text file in the same folder.
Assuming WordPress is installed on www.mysite.com. The file name is setup_1_0.zip and the link display is Setup 1.0.
I am open to the file format how this information is stored as long as I can upload that file via FTP, too.
How can I embed this information inside a Custom HTML widget to get a valid download link with the text taken from that file?
How to automate the process of uploading latest software's build and download link creation in WordPress?
Based on your logic.
You are trying to automate the download process of your latest software version.
You don't want to update things manually and you just want to upload your latest build in the /download/ folder. (Only drop your latest version using FTP; that's all)
This is how I would do it:
Referencing those questions:
Get the latest file addition in a directory
How to force file download with PHP
I propose two solutions: First two separte codes, Second One inline code.
Just for educational purpose
First solution: Quick and short usage:
(You might need a way or a plugin to activate running PHP in Widget; this plugin helps PHP Code Widget)
<?php
$path = "download/";
$latest_ctime = 0;
$latest_filename = '';
$d = dir($path);
while (false !== ($entry = $d->read())) {
$filepath = "{$path}/{$entry}";
// could do also other checks than just checking whether the entry is a file
if (is_file($filepath) && filectime($filepath) > $latest_ctime) {
$latest_ctime = filectime($filepath);
$latest_filename = $entry;
}
}
echo 'Download '. $latest_filename . '';
?>
Second solution:
(Again, you might need a way or a plugin to activate running PHP in Widget; this plugin helps PHP Code Widget)
A) Create download.php in http://www.example.com/download.php
Add the following code:
<?php
$path = "download";
$latest_ctime = 0; //ctime stands for creation time.
$latest_filename = '';
$d = dir($path);
while (false !== ($entry = $d->read())) {
$filepath = "{$path}/{$entry}";
// could do also other checks than just checking whether the entry is a file
if (is_file($filepath) && filectime($filepath) > $latest_ctime) {
$latest_ctime = filectime($filepath);
$latest_filename = $entry;
}
}
// echo $latest_filename; un-comment to debug
$file_url = 'http://www.example.com/download/'.$latest_filename;
header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"" . basename($file_url) . "\"");
readfile($file_url); // do the double-download-dance (dirty but worky)
?>
B) in your WordPress HTML Widget add the following code
<?php
$path = "download";
$latest_ctime = 0;
$latest_filename = '';
$d = dir($path);
while (false !== ($entry = $d->read())) {
$filepath = "{$path}/{$entry}";
// could do also other checks than just checking whether the entry is a file
if (is_file($filepath) && filectime($filepath) > $latest_ctime) {
$latest_ctime = filectime($filepath);
$latest_filename = $entry;
}
}
echo 'Download '. $latest_filename . '';
?>
Further explanation:
A) is responsiple for downloading the latest software build automatically.
B) is responsiple for displaying Latest build name and Creating the link.
Now, You only need to upload one file to your /download/ folder which is your latest build (setup_1_0.zip, setup_1_1.zip, setup_1_2.zip ...etc. The proposed solution will check creation date regardless of file's name.)
Important note: You can see that the latest file checker function is repeated twice; once in download.php and once in WordPress Widget. Because if we combine in one file we will get header already sent error.
Dose this answer your question please? Kindly feedback.
I have followed the explanation given here to write the query result to a file.
But in this case I have to open and write the files headers first. Then keep writing/appending the query results one by one for multiple queries. This appending part I have written as a function. The problem that my script write the file with the headers (from the first part) only, it does not follow the fputcsv commands present in the function when it is called. Can you help me in solving this.
Here is my code to first open the file:
<?php
$fp = fopen('php://output', 'w');
$headers = array("Index","Gene_symbol","Gene_Name","Human_entrez","Rat_entrez","Mouse_entrez","DbTF","PMID");
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="export.txt"');
fputcsv($fp, $headers,chr(9));
header('Pragma: no-cache');
header('Expires: 0');
?>
Then the query part is somewhat like this (I have multiple of such query parts each one calling the same function) :
<?php
if (is_numeric($sterm))
{
$query="select * from tf where entrez_id_human=$sterm || entrez_id_rat=$sterm || entrez_id_mouse=$sterm";
$result=mysql_query($query) or die(mysql_error());
if (mysql_num_rows($result)==0)
{echo "<tr><td align='center' colspan=6> $sterm not found! </td> </tr>";}
elseif (mysql_num_rows($result)>0)
{result_disp($result);}
}
?>
then writing the result to file via a function is here:
<?php
function result_disp($results)
{
if($fp && $results)
{
while ($rows = mysql_fetch_row($results))
{
fputcsv($fp, array_values($rows),chr(9));
} die;
}
}
And finally closing the file at end of script
fclose($fp);
?>
Thanks
Your first problem is that your file handle does not have scope within the function. The best way in my opinion is to pass it into the function:
....
elseif (mysql_num_rows($result)>0)
{result_disp($result, $fp);}
....
function result_disp($results, $fp)
{
if($fp && $results)
{
while ($rows = mysql_fetch_row($results))
{
fputcsv($fp, array_values($rows),chr(9));
} //DO NOT PUT "die()" HERE
}
}
Your second problem is the "die()" statement inside the function. The purpose of "die()" is to stop the script entirely. It is PHP suicide. So, if you leave it in, your script will halt at the end of the first call of result_disp. That means not only would you never reach fclose($fp), you'll never reach any other call to result_disp.
Your third problem is that you are using mysql_* functions. These are deprecated (no longer in use) for several reasons. I have personal experience with database connection freezes caused by it. You should switch to mysqli or PDO.
I can't get my Yahoo! Application Platform to run I keep getting denied access even though their policy file accepts requests from any domain.
OK: Policy file accepted: http://social.yahooapis.com/crossdomain.xml
Error: Request for resource at http://social.yahooapis.com/v1/user/<user id>/profile?oauth_signature_method=HMAC-SHA1&lang=en-US&oauth_consumer_key=<key>&oauth_token=<long ass token>&oauth_version=1.0&format=json&oauth_nonce=<blah blah>&oauth_timestamp=1262846353®ion=US&oauth_signature=<foo bar> by requestor from http://<my domain>/YOSSimple.swf is denied due to lack of policy file permissions.
The url works btw, I editted some stuff out since it has my keys and stuff.
Links to the stuff I'm trying to do
http://developer.yahoo.com/flash/yos/
http://developer.yahoo.com/flash/yos/examples/simple/YOSSimple.fla
YOSSimple properly creates the url actually since if I type it in my browser I'm prompted if I want to download the file that contains information regarding my profile.
But it just wont open it in Flash.
I'm guessing that it's not loading the policy file automatically. You should try using
Security.loadPolicyFile("http://social.yahooapis.com/crossdomain.xml");
Do you have a webproxy installed with which you can monitor what files exactly are loaded? My favorite is Charles but there are also free FF plugins like Httpfox
EDIT:
I think I know what's going wrong. It's going wrong the other way around, the swf from yahoo is trying to access your swf, but doesn't have the correct permissions. Would you try
Security.allowDomain( 'http://social.yahooapis.com/' );
http://www.ieinspector.com/httpanalyzer/
use HTTP analyzer to see whats happening?
also check your not missmatching http://www. with http:// because flash treats them as different domains
also are you running the code locally on your machine. It could be your local security settings
A simple WebProxy will fix this:
<?php
// PHP Proxy
// Loads a XML from any location. Used with Flash/Flex apps to bypass security restrictions
// usage: proxy.php?url=http://mysite.com/myxml.xml
$session = curl_init($_GET['url']); // Open the Curl session
curl_setopt($session, CURLOPT_HEADER, false); // Don't return HTTP headers
curl_setopt($session, CURLOPT_RETURNTRANSFER, true); // Do return the contents of the call
$xml = curl_exec($session); // Make the call
header("Content-Type: text/xml"); // Set the content type appropriately
echo $xml; // Spit out the xml
curl_close($session); // And close the session
?>
Modify the web proxy example above to support multiple options as follows:
$sOptions = "";
foreach($_GET as $sIndex => $sValue) {
if ($sIndex == 'url') {
$url = $sValue;
}
else {
if (strlen($sIndex) > 0) {
$sOptions .= "&" . $sIndex;
}
if (strlen($sValue) > 0) {
$sOptions .= "=" . $sValue;
}
}
}
$url .= $sOptions;
$session = curl_init($url); // Open the Curl session
