Note that this function can fail if access to the file or listing is denied. This could be because the file is read solely or it’s open. The model of this perform in the FileTime software is a little more complex because it does this error checking. There are a couple of things you need to observe about setting the last access time. If we do not do this then once we set the last write or creation time then this counts as a file entry. The working system will replace the final access time to the current time.
The following is the solution with the assistance of Joe Ferris. Note that point resolution might differ from one file system to another.
Obviously this varies on sever specs and the size of the error log. For most instances, it’s nonetheless perfect to make use of the `file_exists` method. Filemtime() returns false on failure so within the first instance it’s going to by no means show the date modified. The above code works fantastic when you place it on each web page you desire a date stamp on. You need to make use of filectime with filemtime to assure you get copied information that aren’t modified however are obviously new. On the Windows system filectime() returns the creation time.
In the FileTime software we solely allow you to choose recordsdata that exist. The sort of error we are prone to experience is “the file is opened by one other software if you try to entry it”. This kind of error additionally applies to the remainder of the code examples on this article. The following code assumes that there are labels to show the occasions. It then gets the file date and time and shows it in a label.
I would have been suprised if this may have labored via HTTP, as I didn’t assume web servers uncovered that knowledge. Get_template_directory and get_stylesheet_directory don’t do the same thing. Restating the answer from @JacobPeattie within the comments above.
File_path − The path of the file for which the last modification time shall be discovered. Get and set a listing date and time in coordinated common time . Get and set a file’s date and time in coordinated universal time .
Perhaps if the web server allows directory listings, you can get the information there. The identical goes for all the other features starting with get_template_… For me the filename involved was appended with a querystring, which this operate did not like. Let us now get the final modification time of a file as a date which is in human readable type.
Child themes do not allow you to override any file by placing a new file with the identical name within the youngster theme. That only works with templates loaded via get_template_part. This perform filemtime() makes use of the server file system so it works for native systems solely, we won’t use this perform to get the modified time of any remote file system.
Also any kind of access on the file updates the last entry time. So if you check the final access time that has been set accurately then this updates the final access time. This is a quandary that you should bear in mind whereas testing. The methods website development shriji solutions we use to obtain the date/time are all static. This implies that we don’t need to create a File object before we use these strategies. You just need to pass the total file path to the method and this returns a DateTime object.
While testing on Windows, I observed that the precision of filemtime is simply 1 second. However an issue may come up if some redirection happens. In such a case, the server HTTP response contains no Last-Modified header, but there’s a Location header indicating the place to search out the file. The operate below takes care of any redirections, even a number of redirections, so that you simply attain the true file of which you want the last modification date. This turns out to be useful when you want just one ‘last up to date’ message on the frontpage of your web site and nonetheless taking all recordsdata of your web site into account.
