PHP read from uploaded text file?

由 China☆狼群 提交于 2019-12-03 02:41:00
问题 If I upload a text file via a form, is it possible to output its contents directly from the $_FILES variable rather than saving it onto the server first? I know this is a security risk, but it will only be run on a local machine. Any advice appreciated. Thanks. 回答1: The file is saved to temp directory the moment it's uploaded, but you can use $_FILES['uploadedfile']['tmp_name'] to read it without having to save in a permanent place. 回答2: Doing file_get_contents($_FILES['uploadedfile']['tmp

Node.js Busboy parse fields and files seperatly

I was wondering if it is possible to get Busboy to parse the fields and files separately. (I have removed bodyParser as you can fill the hard drive with temp files very easily.) For instance - middleware which parsers post fields (used on all POST requests) if (req.method === 'POST') { var form = new busboy({ headers: req.headers, limit: { files: 0 } }); form.on('field', function (fieldname, val, valTruncated, keyTruncated) { req.params.body[fieldname] = val; }); form.on('finish', function () { next(); }); return req.pipe(form); } else { next(); } Then on upload pages use the following, which

Drag & Drop File Upload

由 柔情痞子 提交于 2019-12-03 01:22:22
问题 So I'm struggling a bit to find what I'm looking for and how to implement it. I have a basic PHP file uploader working, in that a user presses a custom upload button, selects a file and then using JS, it checks for a change (Ie. the user selecting a file) and then submits the form which uploads the image fine. What I also want now is a drag & drop to upload area. So the user can drag an image from their file explorer and drop it in a designated place (not the whole page) and then once that

generate random string in php for file name [duplicate]

由 馋奶兔 提交于 2019-12-03 00:28:23
This question already has an answer here: PHP: How to generate a random, unique, alphanumeric string? 27 answers How would I go about creating a random string of text for use with file names? I am uploading photos and renaming them upon completion. All photos are going to be stored in one directory so their filenames need to be unique. Is there a standard way of doing this? Is there a way to check if the filename already exists before trying to overwrite? This is for a single user environment (myself) to show my personal photos on my website however I would like to automate it a little. I don

Upload Excel File and display in Grid in asp.net MVC

由 江枫思渺然 提交于 2019-12-02 21:15:37
I need to export the Users List from excel to my asp.net mvc(C#) application.

Is there any easy way to do it, like a plugin? Mike Rosenblum I think that it would be best, in this case, to use ADO.NET.
