This is what that "hard code" is. Your mod without it, is not working for me. The Login works fine the register page had no code to show the button at all. The login did.

Ok lots of posts and code but this mod is to good not to share the bugs.

Also, I have mentioned that when one logs in with FB they are not redirected to the index page. Log in without FB and the redirect works fine.

Bangs head against the wall. It is not hard coded into my mod. I use template variables.

{FBREGO}
{FACEBOOK}
{FBLOGIN}
{FBOGMETA}

They are the four template variables that I use and I do not hard code into a template except for the wrapper that houses the template variable.

<div class="panel">
<div class="inner"><span class="corners-top"><span></span></span>
<h2>{SITENAME} - {L_REGISTRATION}</h2>
<!-- IF ERROR --><dl><dd class="error">{ERROR}</dd></dl><br /><!-- ENDIF -->
<dl><dd>{AL_FB_REGO}</dd></dl>
<span class="corners-bottom"><span></span></span></div>
</div>


So in this case the wrapper for the registration is

<div class="panel">
<div class="inner"><span class="corners-top"><span></span></span>
code inside here
<span class="corners-bottom"><span></span></span></div>
</div>


Hard coding into the template file will break the mod because you are not allowing for the if statements, the posted variables and template_assign_vars to be used.

95 % of the users of PHP are not coders I know I am not. However I have asked at least three times where in this code did I make a file edit, yes for many of us you have to spell it out. So once again, my ucp_register.php is above and coded per your per your own instructions, I ever asked you in a PM that I may have the edit in the wrong place because your instructions say after X find </div> well it so happens I have two or three more </div> in my file than your instructions ref so which one. It may not even be that. You have my edits so for us dumb folk, where in the edit did I go wrong for I simply do not see it.

I apologize about the hard code but based on my edit (which appears wrong) the registration does not work i.e. show an icon. I provided my edits above, you said my overall_header.html could be wrong or my ucp_register.html and my Index_body.html So they have been here on this board for two days waiting for someone who is a coder to say, "Ah your error is here i.e. the lingo Find X move to or add above or below.... No one has done that.

Please look at them and then tell me what I did wrong? I do appreciate your time, look at it this way you imagine e me trying to explain to you about pumped diodes for a a kilowatt class laser do you think I would expect you to understand, no. So in my case you are trying to explain to me something I am not an expert in i.e. coding so walk this dog to the food bowl please.


I also mentioned that if you use your code to log in, the redirect at least for me does not i.e. if I log in normal, my bard redirects to the index page. If I use the FB login, it does not do that it.

M8 thanks for the help trust me I understand your pain, you get 100s of these type requests per week. Please I emplore you to look at me edits and literally spell out my error.

A fantatci mod and I want to use it the right way, your way :)

Funny fact is I have been a sound and lighting engineer for over 10 years. So I knew exactly what you were talking about. Me looking at your files on here is no use to me at all due to the fact that I cant see errors or how your boards php functions. I do see you have a few mods installed. So sending me code in code tags really makes it hard for me to understand. I cant put it any easier from I have done really. The only thing left is to actually ftp into your board and fix the errors shown to me in firebug.

Thank you so much for putting up with my crud, I appreciate your FTP offer and sent you the info.

I can only imagine the demands you get and I was not very helpful or polite and you still took the high ground and offered to assist. I am humbled and appreciate it.

Great mod look forward to the errors you find and the lessons learned from them.

Nps man.
I actually updated the redirect with my latest code and fixed the registration somehow it was not working which it can do time to time.
I still have not heard a thing from facebook and dont expect to for at least a year as that was how long it took for the last reply from their lazy devs.

They spam us with their emails saying our code is wrong and yet they don't release anything to say what is wrong or update there documents so I am really at a lost. As far as I can see the code for this mod is the most current and has no securities holes so all previous mods that have not updated from the rest api are really running a security risk according to facebook devs.

So thanx to facebook I am stalled and don't know what to do or if anything is wrong
