xmlHttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded')

For some reason a + gets to be replaced by a space -> <- when sending a requset like this

data='ABGHJKIJH/SDSSDSD+'
xmlHttp=new XMLHttpRequest()
xmlHttp.open('POST',cgi,true)
xmlHttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded')
xmlHttp.send('v='+encodeURIComponent(data)) 

explenation please why my + is getting replaced ? Also seems like xmlHttp.setRequestHeader('Content-Type', 'text/plain') doesnt work at all ?

ps how do i solve the space folowed by space that gets replaced by once space instead of two?

[nitro2k01]

Hmm, can you please show me the server-side code you're using? (Relevant parts)

[gert cuykens]

never mind i found a solution and convert it into base64 first folowed by urlencoding

PS why does firefox corrupt my blob's when i display them in a textarea ? The null character (\0) gets destroyed ?

[nitro2k01]

Why in the world do you want to store something containing a \0 in a textarea??

[gert cuykens]

lol i dont know, JPEG files are full of \0 characters. And when you delete them you get a different picture. So why do they get deleted automaticly in a textarea and how can i tell firefox not to do that?

[nitro2k01]

A jpeg file in a textarea? Sounds hilarious to me. Maybe you could keep it base64-encoded until you recieve it on the serverside again? You could also try using using the htmlentities function and print the jpeg to a hidden form field:

<input type="hidden" name="foobar" value="<?PHP echo htmlentities(jpegdata); ?>" />

[nitro2k01]

Or, shall I add, try to fins a solution that doesn't involve sending the image to the user.

[gert cuykens]

i have two choises, the server puts the image in session memory or it gets stored in a client text area ?

Witch one would you pic ?

[nitro2k01]

choices, which, pick
Where do you get the image data from? A file? If so, why not simply pass the file name or something?

a mysql db. You know phpmyadmin? I think i can do much better. I will show you when its finished, right now i am trying to figure out the best way to handle blob's

[tarsus]

If I'm understanding correctly what you're trying to do here, I think the key will be a PHP file that queries for your blob data, echoes it out, and then sets its own MIME type to image/jpeg (or whatever). Then all you need on your page is an <img src="image.php" />, and your JavaScript can change the src to pass whatever information you need for your query:

image.php?whatever=whatever

Picture a database with one column that contains blob information. Now think of a sql statemant that updates one of the blob's (in this case jpeg). Believe me you will have some freaking looking sql statemant with a lot off weird characters. I am trying to visualise this sql statemant trough a textarea with as little overhead as possible currently phpmyadmin visualise it with a hex number witch is not a good idea for big files.

Again wait until my version is finished and have my gpl license stampelt on it, and it will all be clear
