Title: [MOD] - AJAX - register with username suggestion
Post by: thunderstrike on November 16, 2007, 12:36:11 AM
Is my 1st Ajax code. Is for suggest username to user for register new name in gallery.

1 - Is check for exist username.
2 - Is check for filter username.
3 - Is check for exist index name (all lang is use. ;)).

1 - If username exist - message is show (red) - say is no possible for use (exist in DB).
2 - If name find in filter (you add) - is no possible for use (reset form).
3 - If enter suggest name in lang array, is show to user for name of use (check with exist name in DB. ;)).

This MOD is work with page header - is no problem. Is use only for register form (test in: 4images v1.74).

// Step 1

In register.php file,

find:

Code: [Select]
if ($user_info['user_level'] != GUEST && $action != "activate") {
  show_error_page($lang['already_registered']);
}
$content = "";

add after:

Find:

// Step 2

In includes/db_field_definitions.php file,

add in top ?>:

Code: [Select]
$additional_index_name_filter_check = array("sex", "test", "webm", "adm", "await", "user", "guest", "password", "email");

This is filter for bad word if type username in register form.

// Step 3

In includes/page_header.php file,

find:

Code: [Select]
"url_captcha_image" => $site_sess->url(ROOT_PATH."captcha.php"),

add after:

Code: [Select]

// Step 5

In templates/your_template/register_form.html file,

find:

Code: [Select]
<input type="text" name="user_name" size="30" value="{user_name}" class="input" />

replace:

Code: [Select]
<input type="text" name="user_name" size="30" value="{user_name}" id="txt1" onkeyup="showHint(this.value)" class="input" />
              <br />
              {lang_register_suggest_text}<span id="txtHint"></span>

// Step 6

In templates/your_template, create file: clienthint.js .

Add:

Code: [Select]
var xmlHttp

function showHint(str)
{
if (str.length==0)
  {
  document.getElementById("txtHint").innerHTML=""
  return
  }
xmlHttp=GetXmlHttpObject()

var url="register.php"
url=url+"?action=register_suggest&q="+str
//url=url+"&sid="+Math.random()
xmlHttp.onreadystatechange=stateChanged
xmlHttp.open("GET",url,true)
xmlHttp.send(null)
}

function stateChanged()
{
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
 {
 document.getElementById("txtHint").innerHTML=xmlHttp.responseText
 }
}function GetXmlHttpObject()
{
var xmlHttp=null;
try
 {
 // Firefox, Opera 8.0+, Safari
 xmlHttp=new XMLHttpRequest();
 }
catch (e)
 {
 // Internet Explorer
 try

  }
 catch (e)
  {
  xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
 }
return xmlHttp;
}

// Step 7

In templates/your_template/header.html file (templates/your_template/layout/header.html for user use universal layout TWEAK) -

find:

Code: [Select]
{if has_rss}
<link rel="alternate" type="application/rss+xml" title="{rss_title}" href="{rss_url}" />
{endif has_rss}

add after:

Code: [Select]
{if register_suggest}
<script src="{template_url}/clienthint.js"></script>
{endif register_suggest}

I think is all ... I no support AJAX JS file - I no edit other of URL .
If work, please say ... ;)

function validchars($name){ //If it have invalid chars will return 0
  $regex_valid_variable_name = '^[A-Za-z_-][A-Za-z0-9_-]*$';

  xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
  }
 catch (e)
  {
  xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
 }
return xmlHttp;
}

// Step 7

Öffne: templates/your_template/header.html

finde:

Code: [Select]
{if has_rss}
<link rel="alternate" type="application/rss+xml" title="{rss_title}" href="{rss_url}" />
{endif has_rss}

Füge darunterr:

Code: [Select]
{if register_suggest}
<script src="{template_url}/clienthint.js"></script>
{endif register_suggest}

Die URL der JS Datei muss so bleiben! Wenn der Pfad geändert wird, wird diese Modifikation nicht mehr funktionieren! Also bitte an die Anleitung zu 100% halten!
