Discussion on online preview of PDF and Word documents in forums

Forum Engine: Discuz! 2.5

Tools: Flexpaper1.5.6 secondary development version

This article focuses on the general ideas and related technical difficulties. It is a small development in my spare time and only for discussion ,,,

Effect

Why does the Forum need the online preview function? Why does the company's forum need this function? Do you still need to download it? You won't be able to read it directly ,,,

For the secondary development of flexpapaer, refer to the previous article: Secondary Development Summary and Discussion of flexpaper.

The main difference here is diyflexpaper. mxml.

Here, this. loaderinfo. Parameters. url is used to obtain the address parameter for loading the flash, not the parameter of the current URL address. The main purpose of this modification is to pass the parameter when the Forum loads flexpaper.

Now, flexpaper is ready. Let's add a plug-in to the Forum.

Http: // 192.168.0.200/flexpaper/diyflexpaper.swf This Is My flexpaper address
Number of parameters: 3

Parameter prompt:

Enter the reader width. Enter the height of the reader. Enter the flash Address to be opened:

Other Default values: after submission, add the user group permission. You can see the following mark when posting:

The flash Address opened here is.../SWF/1.swf. the flash Address is discussed below:

1. This address is the file address that has been converted from PDF to SwF. This article is manually converted and uploaded to the server. How can this address be used by general users?

This forum is all developed using PHP. I really don't know it. Otherwise, I can write a background Conversion Program. Here, let the user input the address as the file address of the client PDF or something, after submission, the Conversion Program uploads and converts the files, which is perfect.
