    <p>There are many questions with this title , but no one helps. My application should handle file uploads with size up to 2 GB and it should be done through a browser , not something like a FTP file uploader.<br> I'm aware of configuration settings should be done for example on <code>php.ini</code> . but there are some questions in my mind : </p> <ol> <li><p>Is something like <strong>uploadify</strong> library a good solution for this file size or there are better alternatives? </p></li> <li><p>because of the big size , maybe this is desirable to have <strong>pause/resume</strong> functionality in it. is it possible to implement this functionality through HTTP file transfer via a browser? if yes , how to? </p></li> <li><p>some people talk about some type of vulnerabilities like <strong>DOS ATTACKS</strong>. is it in this case a serious issue and what are the considerations for this types of attacks? </p></li> </ol> <p>if there are any extra recommendations and suggestion , please tell me about them. </p> <p><strong>UPDATE:</strong> some have suggested to do the job using FTP file upload. should it be done by dedicating each user a FTP account to let them upload files using FTP clients such as FileZilla ? if so , how incoming processes should be handled . for example I give each user a directory like <strong>/home/user1</strong> and he uploads his files into this directory. Now how should I fetch uploaded file data and save it to database according to user session data.<br> Generally , I mean how to script over this FTP file uploading system?<br> or if it is impossible please tell me. </p> <p>please help.</p>

    1. COEven if it's possible, 2 GB through a browser is still a *lot.* It's likely to take hours or days. If the connection gets flaky for just a second, aborted connections usually can't be resumed. Do you have a use case where you really need this on a regular basis?

    2. COThis is just theory coming from me, I haven't tried any of this in practice so here goes: you can use FileReader API to read the file using newer browser and then manipulate it to your liking. That's what uploadify does if the browser supports it, from what I can remember. That also means you can send file in small chunks to the webserver. The problem is gluing the pieces together. The other problem is unstable behaviour of browser when it comes to reading such large files. Googling FileReader API might help more.

    3. CO@Pekka웃 : my application should allow up to 2 GB file uploads. but I don't know what do you mean of "regular basis". I know it should be done via a browser not for example a FTP client. but if you mean for example using Flash , it is possible

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
