Errors detection is done to check if a plugin can work properly. Hiding the error is not the solution. Of course, you can do this at your own risk, but with each plugin update, you will lose these changes. Skip to content WordPress. Skip to content. Resolved kjustice kjustice 1 year ago. If I add the passthru switched parameter to the end of the command, a Process object returns to the Windows PowerShell console.
The nice thing about this is that I can use this Process object to track and work with the newly created instance of Notepad. The command to start the Notepad process and to return a Process object to the Windows PowerShell console is shown here:.
If I store the returned Process object in a variable, I can then use it to obtain additional information about the process. I then examine the start time of the process, and finally I stop the process by piping the Process object to the Stop-Process cmdlet:. Another cmdlet that contains a passthru parameter is the Copy-Item cmdlet.
When I use the cmdlet to copy a file from one location to another location, nothing returns to the Windows PowerShell console. In the following command, I copy the a. Nothing is returned to the Windows PowerShell console:.
If I would like to see information about the copied file, I use the passthru switched parameter. The revised syntax is shown here:. The returned object is an instance of a FileInfo object. I can now directly access any of the properties of the FileInfo object. My favorite property is the FullName property that points to the complete file name as well as the path to the file. These commands are shown here:. By default, when using the Import-Module cmdlet to import a module into the current Windows PowerShell session, nothing is returned.
If you trying to output a user-written file on a page for verifying, editing, etc, you'll want to use fopen , fread , htmlentities to avoid malicious code. Text from fpassthru, while not parsed per se can still mess up the display of a page or at least it did for me! I believe the following problem is a result of using sessions and fpassthru together. I have a subscription based site which protects large video files WMV format between MB by storing them beneath web root.
If the user is valid session vars created from sucessful login the script then creates the necessary headers to trigger a 'Save As' download box, opens the file from beneath web root and sends it using fpassthru. The problem is as follows: The user should be able to click other links on the site whilst a file is downloading.
But when they do so, the requested page won't load until the download is complete. As this download script is a seperate PHP request, the user should be able to load other pages on the site whilst the file is downloading. At time of writing, I've tried almost everything to remove this bug.
There must be a problem with using a PHP script rather than a direct web server link to download files.
Thats all Greetings, omega2k. Hope that helps. Note that if you use these two headers from a previous example: header 'Cache-Control: no-cache, must-revalidate' ; header 'Pragma: no-cache' ; before sending a file to the browser, the "Open" option on Internet Explorer's file download dialog will not work properly.
If the user clicks "Open" instead of "Save," the target application will open an empty file, because the downloaded file was not cached. The user will have to save the file to their hard drive in order to use it.
Make sure to leave these headers out if you'd like your visitors to be able to use IE's "Open" option. A few notes on using fpassthru to php-driven download links that pop up a "Save As.. I found that the download progress dialog was remaining up for several seconds after the transfer was completed, before telling the user it was complete.
This was fixed by adding the following header: header "Connection: close" ; This will cause the connection to be closed as soon as the transfer is complete, rather than waiting for a timeout.
If you have multiple periods in the filename, you might wind up with a filename with numbers in brackets such as myfile-[1][0]-windows. Through no amount of futzing of headers was I able to get the filename to be set properly when the actual transfer was initiated via a refresh META or via headers.
I don't know if this is also an MSIE only issue or not. If 'download. I've tried all of these renditions of this elusive task. NONE of them have worked for me. And when i say work, i mean where i can click some sort of link and have a file Save As In every other browser i've tried Safari,Firebird,Netscape pc and mac all have worked where it downloads to my desktop or asks me to save it in a certain place.
I'm using the fpassthru function because i have files that must not be served by the webserver. Found a workaround for the MSIE cache bug that puts brackets around dotted items I posted about a while back e. If you encode all of them including the last dot , then MSIE sticks an extra bracketed number at the end of the file e. Properly named files. PJ's ulimit example is nice; however, if you include multiple commands in the script after the ulimit command, each gets its own, seperate 60 second time slot!
Most programs hang for other reasons than CPU hogging for example, waiting for a database connection so for most purposes the number 60 is rather too high. About the problem of zombies, you may call a bash script like this: ! I had an issue when i used exec I think we were echoing information on the test. The only thing to note is that you need to provide the fuull path.
If you sometimes get no output from passthru use system instead. This solved this problem for me php 4.
With apache 2. Apache 2. I guess that buffering behaviour is by design - but caused problems for me with IE adobe acrobot 5 plugin.
