Hi guys

I'm working on a WYSIWYG editor - more like tweaking it and for some reason I need to put in a maximum line length check which goes as such that as the user types in the textarea and lets say during typing he reaches a maximum line length it automatically puts a carriage return and puts him on another line... anyway how to do this guys....

Welcome to the Asylum, subhan - next time, please open a new topic.

Basic idea here could be to have the input() calls in a <body onload> and then document.write() the rest of the page ( though I bet the standard gusy will run me down on this - and they're right. But a page asking for a username/password in javascript before displaying? come on were so far of the 'good practices' axis that it doesn't even begin to matter).

Now, if you want to secure your site, I suggest you read up on '.htaccess protection' for this is what you'd be usually looking for if you want to protect a site with a username/password that's being asked before the site's show.

So long,

->Tyberius Prime

HELP AGAIN! All of a sudden word wrap is not working on the textarea in my project where I wanted it to work!!!
Is there any way in Javascript that inserts in realtime as you type line breaks when a maximum line length is reached...

HELP!!!!!!!

look, you've obviously broken the built in word wrapping and are much better of figuring out how, and restoring it ( don't you have a version contral and can check what you changed?) than to try to assemble a half-baked javascript solution that will basically never work as nice as the built in one ( word wrapping is not simple!)

/me stomps Tyberius Prime with a standard stick.


What about, instead of some ugly document.write(), adding the following line to the .htaccess:

code:
php_value auto_prepend_file /system/checkAuthentication.php


The /system/checkAuthentication.php script will check if a cookie is present and either display the requested page or an authentication form posting the data to the same URL and set the cookie.

This way the login/password pairs can be stored directly in the PHP script or in a database. So it's rather safe.

Clean, simple and doesn't mess up with the actual site.

But might mess with rowser caching, and relies on (more easily spoofed ) cookies instead of standardized http auth .

Anyhow, the guy asking the question wanted javascript. Your solution does require php, and a properly configured webserver :>


Oh, and I guess if done to simpleton, it will do foul play if the actual site uses something stupid like is_empty($_POST)
