Generating URL

[Thomas]

I am making a image uploading website and i have got it to upload the image to a mySQL database and display the image however i am not sure how i can generate a a random URL ending which links to the image they uploaded.
Not very well explained but i'm sure you know what i mean.

e.g www.domain.com/w7djw38d

I guess you'd have to write a PHP script to pull the image and use an htaccess rewrite rule to make the URL. Sorry I can't be of more help though.

Ok, anyone want to explain how htaccess works?

Use

Rand() 

to generate a random number.

to generate a random number.

So I could you 'Rand()' to do:

'www.domain.com/21891' ??

if yes, how do I assign that to the users image?

[triston220]

You could check a GET argument (E.G. imageid) to get the relevent image.

Example:

Yoursite.com?imageid=3569346

If I rember correctly, Rand() takes two argunents. These are Lower Bound and Upper Bound.

Using a GET would be a security risk. Umm phpacademy has a similar tutorial but with a url shortener you could use the generating bit from that tutorial for it.

How would it?

$imageid = Strip_tags(mysql_real_escape_String($_GET['imageid'])) //Remove anything stupid.
$imageid = (int)$imageid //Cast type to integer.

I wouldn't say it's a security risk, but yeah. Don't judge just when I was making something someone told me about using GET and random numbers in URL's was dangerous but I can't remember. So try it it's not that bad.

Ok so I'm assuming you store the images on the sql like: IMAGE ID | IMAGE FILE (And then maybe some meta data)

So first you need to make the image displayed be called by:
image.php?id=3453245345

Just have the number auto-increment, you'll avoid problems down the line. Then in order to format it to domain.com/3453245345 you need to use mod_rewrite.

You probably need something like this:

RewriteEngine On
RewriteRule ^/([0-9]{4})$ /image.php?id=$1 [L]
