I cant seem to get this to work. I am trying to emulate this script
http://www.shawngo.com/gafyd/index.html , checks the username with a
database to see if its available.
I have tried the JSON + Jquery but i cant seem to get it to send the
current value of the text field.
Here is what my HTML Template looks like.
My Header includes:
<script src="/java/jquery-1.3.2.js"></script>
---
The main template:
<form method="post" action="index.pl"
enctype="application/x-www-form-urlencoded" name="reg">
<input type='hidden' name='rm'
value='registrationemail' />
<font color="red">Username: </font></font><input type="textfield"
class="registrationfields" size="10" id="user" name="r_username"
onkeyup="exported_func( ['user'], ['test']);">
<TMPL_VAR NAME="TEST">
<span id="ajax_spinner" style="display:
none;">
<img
src="../images/spinner.gif"/></span>
<div id="display_user_details">
</div>
<div id="test">
</div>
<br/>
<font color="red">Password: </font><input type="password"
class="registrationfields" size="10" name="r_password"/>
<font color="red">Password-Check: </font><input type="password"
class="registrationfields" size="10" name="r_passwordcheck"/>
<br/>
First Name: <input type="textfield" class="registrationfields"
size="10" name="r_name"/><br/>
Last Name: <input type="textfield" class="registrationfields"
size="10" name="r_lastname"/><br/><br/>
Email Validation Required within 24 Hours of
Account Creation.<br/>
<font color="red">Email: </font><input type="textfield"
class="registrationfields" size="10" name="r_email"/>
<font color="red">Email Check: </font><input type="textfield"
class="registrationfields" size="10" name="r_emailcheck"/>
<br/><br/>
Country: <input type="textfield" class="registrationfields"
size="10" name="r_country"/><br/>
City: <input type="textfield" class="registrationfields" size="10"
name="r_city"/><br/>
<br/>
How did you find us?
<br/>
<textarea rows=5 cols=20 class="registrationfields"
name="r_find"></textarea><br/>
<br/>
<br/>
<TMPL_VAR NAME="CAPTCHA">
<br/>
<input type="submit" value="Register"/>
</form>
<script>
// show the spinner for AJAX requests
$("#ajax_spinner").ajaxStart(function(){
$(this).show();
});
$("#ajax_spinner").ajaxStop(function(){
$(this).hide();
});
$("#user").keyup(function(){
$("div#display_user_details").html('');
$.getJSON('?ajax=1', function(result){
$("div#display_user_details").html(
result.username
);
});
});
</script>
Here is my CGI STUFF
sub usernameCheck
{
my ($query, $self) = @_;
#my $enteredusername = $query->param('r_username');
# check if its an AJAX submit
if ( $query->param('ajax') ) {
my $usernamecheck = check_usernames($enteredusername);
my $json = to_json($usernamecheck);
print "Content-type: text/html\n\n";
$self->header_add(-type => 'application/json');
print $json;
exit;
}
}
sub check_usernames
{
my ($t) = @_;
# pretend like we're doing some heavy task!
#my $answer = checkdbforusername($t);
sleep 0;
my $userresult = {
username => $t,
};
my $userresult2 = {
username => $t,
};
if($answer == 1)
{
return $userresult;
}
else
{
return $userresult2;
}
}
there is also a sub routine for checking the database, but right now i
am just trying to get it to print the value.
I have also tried cgi::ajax, but i cant get it to work with cgi::app and
html::template, this is a little over my head. Any help is appreciated.
