Get URL to automatically paste username into referral box?

Bfghost · January 29, 2010

Basically, I need to build a referral link/URL that puts the referral name in the referral box at the registration page.

What I want is to have a URL that looks like http://.../register.php/?ref=xxxxx where xxxxx automatically is inserted into the referral box on the registration page. What I don't know is how the URL ending part (e.g. ?ref=xxxx) should be formatted for the xxxx part to be automatically pasted into the referral box, and if any changes have to be made in the code for it to be possible.

Here's the code for the registration page:

<?php
$ref_title = "Register Free";
if($set['recaptcha_enabled'])
{
require_once('modules/recaptcha/recaptchalib.php');
}

$tok_id = sha1(md5(session_id()));

if($_COOKIE['tref'])
{
$ref = $_COOKIE['tref'];
} else {
$ref = $do->get_r_file_url();
$ref = str_replace(array(".html", "/"), "", $ref);
if(eregi('.php', $ref)) { $ref=false; }

setcookie("tref", $ref, time()+60*300);
}

if($loggedin)
{
$error = "You are already logged in.";
$show_login=0;
} elseif($_POST)
{
$username = $do->filter($_POST[1]);
$password = $do->filter($_POST[2]);
$confirm_password = $do->filter($_POST[3]);
$email = $do->filter($_POST[4]);
$alertpay = $do->filter($_POST[5]);
$referral = $do->filter($_POST[6]);
$country = $do->filter($_POST[7]);

if($referral != "") {
$sql = mysql_query("SELECT * FROM users WHERE username='{$referral}'");
$sql = mysql_fetch_array($sql);
$membership = $sql['upgname'];
$drefs = mysql_query("SELECT * FROM users WHERE upline='{$referral}' AND uplinetype<2");
$drefs = mysql_num_rows($drefs);
$mbrshp = mysql_query("SELECT dreflimit FROM upg_options WHERE uo_name='{$membership}'");
$mbrshp = mysql_fetch_array($mbrshp);
$dreflimit = $mbrshp['dreflimit'];

if($membership == "Standard") {
    $dreflimit = $set['stddreflimit'];
}
}

if($set['recaptcha_enabled'])
{
# the response from reCAPTCHA
$resp = null;
# the error code from reCAPTCHA, if any
$error = null;

# was there a reCAPTCHA response?
if ($_POST["recaptcha_response_field"]) {

        if (!$resp->is_valid) {

This should be the part I'm interested in:

regist.php?ref=12345

then

<input type='text' name='referral' value='<?php echo (isset($_GET['href']) && $_GET['href']!='')?$_GET['ref']:""; ?>'>

Bfghost · January 29, 2010

Where should I put that? :wtf:

teamatomic · January 29, 2010

taquitosensei altered the example you posted. Put it back where you got it from.

If I put it in place I get this error:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /......../register.php on line 330

It looks like this:

<tr>
	<td>Referral (optional):</td>
	<td><input type='text' name='referral' value='<?php echo (isset($_GET['href']) && $_GET['href']!='')?$_GET['ref']:""; ?>'></td>
</tr>

There is really nothing wrong with the syntax. Though that not my prefered method to use an abbreviated conditional.

Try:

<?php

$href='http://this.com';

echo (isset($href) && $href !='')?$href:"";

?>

You will see that it works.

When you see that it works use it in your <input> as shown in the example given prior. But change $href='http...';

to

$href=$_GET['href'];//put it with the other get/post conversions and use just the conditional statement.

As to what it is, it is an abbreviated if/else

if (isset($href) && $href !='')

{echo "$href";}

else

{echo "";}

statement?output if true:output if false

Could you please show me how the final code should look like. I don't know where to put the new code to get it working.

citricsquid · January 29, 2010

Line 317/318, the input box. So you want:

        echo "<td><input id='referral' type='text' name='6' value=\"";
if(isset($_GET['href']) && $_GET['href']!=''){ echo $_GET['href']; }
echo "\" class='input'></td>";

Try that instead, it's easier to read and modify.

Still doesn't work, getting "Parse error: syntax error, unexpected '>' in /home/content/90/5569190/html/themes/GeN3/register.php on line 319"

<tr>
	<td>Referral:(optional)</td>
	echo "<td><input id='referral' type='text' name='6' value=\"";
	if(isset($_GET['href']) && $_GET['href']!=''){ echo $_GET['href']; }
		echo "\" class='input'></td>";
</tr>

What's wrong.

Bfghost · January 30, 2010

Problem solved.

All I needed was one string.

$id = $_GET['id'];

Then use $id as the value on the referral string.
