As long as the file to be downloaded is in the same folder as the HTML file, you just need to use the name and extension.
If the file is located in another folder, you'll need to include the folder structure. Create a download button instead of a link.
You can use an image instead of text to create the download link. This requires a button image already on your web server. Rename the downloaded file. This can make it easier for users to identify files that they download from you.
Save the changes to your HTML file. Once you're satisfied with your code, save the changes to your HTML file and reupload it if necessary. You'll be able to see your new download button live on your website. Method 2. Open your site in the WordPress site editor. If you use WordPress to manage and publish your website, you can use the built-in tools to add a download link to any of your pages.
Log into your WordPress dashboard using the admin account. Place your cursor where you want the link to appear. You can put the link in the middle of an existing paragraph or create a new line for it. Click the "Add Media" button. You'll find this above the posting tools at the top of the page. Click the "Upload Files" tab and then drag the file into the window. You can upload a variety of different files, but WordPress may limit the size based on your account type.
It may take a little while to upload files, as most connections are slower uploading than downloading. Add a description for the file. You can enter a description underneath the file in the Add Media window. This will be the text that displays as the download link.
This will insert the download link at the location of your cursor. Note that this will link to an attachment page and not the actual file. This is a limitation of the WordPress software.
Method 3. Open your website in the Weebly editor. Log into the Weebly site and open your web page in the Weebly editor. Select the text or object that you want to turn into a link. You can highlight text in a text field or select an image on your page that you want to turn into the download link for your file.
Click the "Link" button. If you take a snapshot of the VM after installing, and before doing dangerous things, you can later go back to that snapshot and undo anything the script could have done to the VM.
As others have said, the PHP file is executed server-side, unless the server is so badly set up that it will simply serve the source. If you would like to examine what is sent to your client without the possibility of it doing anything untoward, use a text editor like Notepad to open the URL.
The server will interpret the request and send what it would normally send to a browser. Your text editor will receive it, but all a text editor can do is display if for editing. It will never get near a browser or other rendering engine to be executed. What you can try however is to manipulate the URL with the hope that the sysadmin made a mistake. Web servers are typically configured to execute. If a forgetful sysadmin made a copy of the. Finding these leftover files is a cumbersome task, so you might want to have a look on automated URL fuzzing tools.
Finally I recommend using curl to make these experiments, because it won't execute JavaScript or Flash on your machine.
I recently had the pleasure of patching this in a project I inherited, hence why I know about it. Truth being told, you'd have to have some luck that there's an exploit possible and you'd also need to figure out the way the server's filesystem is structured i. You may be in luck if the server is indeed poorly configured as suggested by the comment from Gustavo Rodrigues. A PHP code written in the file, is deleted from the file by the http server before it is sent to the http client.
So an HTML form might reference blah. It's blah. B the HTTP server's php module will execute any php and produce the resultant file to send to the client. Sign up to join this community.

Hi, sounds like a problem with headers, does the same script works for you in browsers like Chrome and Firefox? Hi Bobic, like the warning said your script started the output at row 9. Hi Deepak, does this happen only to these two files types or to any file? Hello, I wanted to download a file and save it to disk. There is no such thing in HTTP. You may add those headers if you want, but they do absolutely nothing. Sadly, this wrong example is present even in the PHP manual. The author must have been really frustrated and added three Content-Type headers.
What would it be like to not having to worry about old versions of Internet Explorer? Note: the quotes in the filename are required in case the file may contain spaces. The code above will fail in IE6 unless the following are added:. Now, the use of Cache-Control is wrong in this case, especially to both values set to zero, according to Microsoft , but it works in IE6 and IE7 and later ignores it so no harm done.
If you still get strange results when downloading especially in IE , make sure that the PHP output compression is disabled, as well as any server compression sometimes the server inadvertently applies compression on the output produced by the PHP script. Historically it had some performance issues and while the documentation claims there are no memory problems, real-life scenarios beg to differ — output buffering and other subtle things.
Regardless, if you need byte ranges support, you still have to output the old-fashioned way.
