Generating a random password without refreshing the page.

[coupe-r]

Here is my code

 

if(isset($_POST['pass_btn']))
{
    $numchars = 8;
    $chars = explode(',','2,3,4,5,6,7,8,9,a,b,c,d,e,f,g,h,i,j,k,m,n,p,q,r,s,t,u,v,w,x,y,z,2,3,4,5,6,7,8,9,A,B,C,D,E,F,G,H,J,K,L,M,N,P,Q,R,S,T,U,V,W,X,Y,Z,2,3,4,5,6,7,8,9');
    $password='';
        for($i=0; $i<$numchars;$i++)
        {
            $password.=$chars[rand(0,count($chars)-1)];
        }
}

 

This is set up so when a person pressing the pass_btn, a password is provided.  This works just fine.  However, it refreshes the page and clears all other data that user may have entered.

 

Suggestions?

Without refreshing you need either javascript or call another script by using ajax which is infact javascript too

I think with javascript with innerHTML you can do this. let me give you a small example in a bit.

-edit: you could of course also assign session or post variables to preserve the data

 

here is an input  field that generates a random number on mouseover.

<input id="pass" type="text" name="pass" onmouseover="document.getElementById('pass').value = Math.random();" value="lalala"></input>

maybe you can use it

So what is the part that bothers you? The fact that the page refreshes, or that the form data disappears? Both of those things can be addressed.

Well, the password generate button is the last part of the form and if they fill out they form and then press the generate button, all there stuff is gone.  Thats the main concern.

 

AJAX may be cool too   Thanks
