Document_size on file upload,

Copy linkTweet thisAlerts:
Dec 04.2005

Hiya guys, I’m new here and have carried out the site instructions. Search for an answer before buggin’ us! No, seriously, I just wanted to see if anyone can suggest an update on a 2003 post here re: checking a file size prior to upload, thus eliminating the server round-trip before telling the user his file is too large.

I am building a site that will include both textual data (a user text upload file) and a MySQL database connection, and a directory full of images. The user will more or less design his own site then. However, I would like to be able to check a file size before it gets uploaded, especially useful if we are talking about a large image.

I know that I can do all the usual tests on the temp file in PHP before it’s admitted. But is there a way using Client-Side Javascript?

Thanks for any help and light you might shed on this.

You can set a file size limit in the form so that files bigger than the specified limit will not upload in the first place. For example to limit it to 1000 bytes add the following field to the form.

<input type="hidden" name="MAX_FILE_SIZE" value="1000">
