php - BLOB Download Truncated at 1 MB Script Works for Files Less Than 1 MB -

-

I have just asked recently and have solved a question related to uploading PDF files which is more than 2 MB , Which is the Blobes in a MySQL database. I had to change some settings in my php.ini file and MySQL maximum packet setting. However, deciding this issue has helped me find a new issue with my script.

Now since I can upload files to my Blob database, I tried to download the file for testing purposes when I went to open the PDF file, so I was very disappointed. I got the following error: Failed to load document (error 3) 'file: ///tmp/test-13.pdf' After further investigation I found that the file is being downloaded, test.pdf, only 1 MB , Which is slightly less than half of its size in the database of slightly more than 2 MB, it is obviously the cause of error.

The following part of the code is part of my script which I downloaded files from the database I'm using to It is at the top of the script and works flawlessly for files less than 1 MB ($ _ $ $ key as request = key => $ Value) {if ($ value == 'Open') {header (); Session_start (); $ Dbh = new PDO ('mysql: host ='. $ _ Session ['osdbbusar'] .. Ops.tns.its.psu.edu; dbname = '. $ _ Session [' opsdb '], $ _SESSION [' Yum '], $ _SESSION [' AMA ']); $ Id = $ key; Download $ Sql ​​= "Select name, type, content, size upload WHERE id = '" $ id "'"; $ Result = $ dbh- & gt; Query ($ sql download); $ Download = $ result-> Fatch ALL (); $ Type = $ download [0] ['type']; $ Size = $ download [0] ['size']; $ Name = $ download [0] ['name']; $ Content = $ Download [0] ['Content']; Header ("content-type: $ type"); Header ("content-dispute: inline; filename = $ name"); Header ("content-length: $ size"); Header ("cache-control: macque = 1"); Header ("PAGMA: public"); Counterpart $ content; Go out; }}

I think that I may have some header details incorrect? I am very confused about what to do. I have searched through php.ini and I have not got any settings which I think I need to change and my max packet setting for MySQL is 4 MB, so Should download 2 MB.

Thanks for any help.

According to ():

A BLOB or TEXT object The maximum size is determined by this type, but the biggest value you actually transmit between the client and the server is determined by the amount of available memory and the size of the communication buffers. You can change the message buffer size by changing the value of the max_allowed_packet variable, but you should do this for both server and your client program. According to

the default value for Max_allowed_packet is 1048576.

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons.

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
