Getting a blank page

affordit · February 10, 2008

Hello all

Using the script below

I enter no username it tells me username is required thats right.

Then I enter a known username and I get username already exists that right.

Then I enter a new username and submit again and I get a blank page ???

Anyone know what im doing wrong?

<?php
// MAKE SURE USERNAME IS ENTERED
$username=$_POST['username']; 
if (empty($username))
{
echo"<a href='add_advertiser.php'>Username is required</a>";
exit(); // stop exec here  
}
// IF USERNAME IS ENTERED VERIFY IT IS NOT ALREADY IN THE DB
$username=$_POST['username']; 
if (!empty($username)) 
{ 
include("sharons_dbinfo.inc.php");
mysql_connect(mysql,$name,$password);
mysql_select_db($database) or die( "Unable to database"); 

$query = "Select username from  login Where username = '$username'";
$result=mysql_query($query) or die (mysql_error());
if (mysql_num_rows($result)>0)
print "That Username is already in use";
exit();
}
// INSURE ALL OTHER FIELDS ARE ENTERED

$address=$_POST['address']; 
if (empty($address)) 
{
echo"<a href='add_advertiser.php'>Address is required</a>"; 
exit(); // stop exec here 
} 

$city=$_POST['city']; 
if (empty($city)) 
{ 
echo"<a href='add_advertiser.php'>City is required.</a>"; 
exit(); // stop exec here 
} 

$state=$_POST['state']; 
if (empty($state)) 
{ 
echo"<a href='add_advertiser.php'>All fields are required EXCEPT company.</a>"; 
exit(); // stop exec here 
} 

$zip=$_POST['zip']; 
if (empty($zip)) 
{ 
echo"<a href='add_advertiser.php'>All fields are required EXCEPT company.</a>"; 
exit(); // stop exec here 
}

$phone=$_POST['phone']; 
if (empty($phone)) 
{ 
echo"<a href='add_advertiser.php'>All fields are required EXCEPT company.</a>"; 
exit(); // stop exec here 
} 

$email=$_POST['email']; 
if (empty($email)) 
{ 
echo"<a href='add_advertiser.php'>All fields are required EXCEPT company.</a>"; 
exit(); // stop exec here 
} 
// EVERYTHING FROM HERE DOWN WORKS FINE

Thanks

You need to show the code that displays the information on the page, we need to see how you are printing your results.

Show us the rest of the code.

Im not displaying anything i am sending an email and inserting into 2 tables everything worked well until I added the section at the top that checks to see if the username already exists.

Here is the whole page that the values come from

<?php
session_start(); // start up your PHP session!
include("client_info3.php"); 
include("top_mid_nav.inc"); 
print"
<html><body>
<br><br>";

if( isset($username) ){
print "<h3>You are already registered.</h3>
To change your username or password go <a href='change_details.php?username=$username&psword=$psword'>Here</a>";
	print "<br><b>See how it works $username, if you log out the registration page will be visible.<br><br>Also if you are logged out you can not get to the Ad Products page</b>";
}
else{
print "
<center><font size='+2'>Registration</font></center><br>
<form action=submit_registration.php method='POST'>
<table align='center'>
<tr>
<td width='125'><img src='b_tipp.png' alt='If you do not have a business you can leave this field blank'>Company Name:</td><td><input type=text name=company size=30 maxlength=100></td>
</tr>
<tr>
<td><img src='b_tipp.png' alt='This will be your username and will be cAsE SeNsItIvE'>Your Name:</td><td><input type=text name=username size=30 maxlength=100></td>
</tr>
<tr>
<td><img src='16x16spacer.gif'>Address:</td><td><input type=text name=address size=30 maxlength=100></td>
</tr>
<tr>
<td><img src='16x16spacer.gif'>City:</td><td><input type=text name=city size=30 maxlength=100></td>
</tr>
<tr>
<td><img src='16x16spacer.gif'>State:</td><td><input type=text name=state size=2 maxlength=2></td>
</tr>
<tr>
<td><img src='16x16spacer.gif'>Zip:</td><td><input type=text name=zip size=5 maxlength=100></td>
</tr>
<tr>
<td><img src='16x16spacer.gif'>Phone:</td><td><input type=text name=phone size=30 maxlength=100></td>
</tr>
<tr>
<td><img src='b_tipp.png' alt='You must enter a valid email address so your new password can be emailed to you'>Email:</td><td><input type=text name=email size=30 maxlength=100></td>
</tr>
<tr>
<td><img src='b_tipp.png' alt='Write a question only you know the answer to. It will be used if you lose your password.'>Verification Question:</td><td><input type=text name=lost_password size=30 maxlength=100></td>
</tr>
<tr>
<td><img src='b_tipp.png' alt='Write your answer to the above question.'>Verification Answer:</td><td><input type=text name=lost_password_answer size=30 maxlength=100></td>
</tr>
<tr>
<td align='center' colspan='2'><br><input type=submit name='Submit' value='Register Now'></td>
</tr>
</table>
</form>
</body>
</html>";
}
?>

And here is the page that processes the values

// MAKE SURE USERNAME IS ENTERED
$username=$_POST['username']; 
if (empty($username))
{
echo"<a href='add_advertiser.php'>Username is required</a>";
exit(); // stop exec here  
}
// IF USERNAME IS ENTERED VERIFY IT IS NOT ALREADY IN THE DB
$username=$_POST['username']; 
if (!empty($username)) 
{ 
include("sharons_dbinfo.inc.php");
mysql_connect(mysql,$name,$password);
mysql_select_db($database) or die( "Unable to database"); 

$query = "Select username from  login Where username = '$username'";
$result=mysql_query($query) or die (mysql_error());
if (mysql_num_rows($result)>0)
print "That Username is already in use";
exit();
}
// INSURE ALL OTHER FIELDS ARE ENTERED

$address=$_POST['address']; 
if (empty($address)) 
{
echo"<a href='add_advertiser.php'>Address is required</a>"; 
exit(); // stop exec here 
} 

$city=$_POST['city']; 
if (empty($city)) 
{ 
echo"<a href='add_advertiser.php'>City is required.</a>"; 
exit(); // stop exec here 
} 

$state=$_POST['state']; 
if (empty($state)) 
{ 
echo"<a href='add_advertiser.php'>All fields are required EXCEPT company.</a>"; 
exit(); // stop exec here 
} 

$zip=$_POST['zip']; 
if (empty($zip)) 
{ 
echo"<a href='add_advertiser.php'>All fields are required EXCEPT company.</a>"; 
exit(); // stop exec here 
}

$phone=$_POST['phone']; 
if (empty($phone)) 
{ 
echo"<a href='add_advertiser.php'>All fields are required EXCEPT company.</a>"; 
exit(); // stop exec here 
} 

$email=$_POST['email']; 
if (empty($email)) 
{ 
echo"<a href='add_advertiser.php'>All fields are required EXCEPT company.</a>"; 
exit(); // stop exec here 
} 

// From here it sends mail and inserts to 2 tables

If you aren't outputting anything with the script, then you will get a blank page... Is the mail being sent/the information being put into the database??

I enter no username it tells me username is required thats right.

Then I enter a known username and I get username already exists that right.

Then I enter a new username and submit again with no address and I get a blank page it should be telling me that the address is required when I remove all of that part of the page that I posted and hit submit with nothing entered in any of the fields except email address it inserts a blank record and sens the mail.

Try something like this then to check if variables are empty:

<?php

if(!empty($var1) && !empty($var2) && !empty($var3)) {

//run code here

}

else { 
echo "Please check that are fields are filled out properly<br>
<input type='text' name='var1' value='$value1'><br>
<input type='text' name='var2' value='$var2'><br>";
}


?>

I got it I had change this

// MAKE SURE USERNAME IS ENTERED
$username=$_POST['username']; 
if (empty($username))
{
echo"<a href='add_advertiser.php'>Username is required</a>";
exit(); // stop exec here  
}
// IF USERNAME IS ENTERED VERIFY IT IS NOT ALREADY IN THE DB
$username=$_POST['username']; 
if (!empty($username)) 
{ 
include("sharons_dbinfo.inc.php");
mysql_connect(mysql,$name,$password);
mysql_select_db($database) or die( "Unable to database"); 

$query = "Select username from  login Where username = '$username'";
$result=mysql_query($query) or die (mysql_error());
if (mysql_num_rows($result)>0)
print "That Username is already in use";
exit();

To this

// MAKE SURE USERNAME IS ENTERED
$username=$_POST['username']; 
if (empty($username))
{
echo"<a href='add_advertiser.php'>Username is required</a>";
exit(); // stop exec here  
}
// IF USERNAME IS ENTERED VERIFY IT IS NOT ALREADY IN THE DB
$username=$_POST['username']; 
if (!empty($username)) 
{ 
include("sharons_dbinfo.inc.php");
mysql_connect(mysql,$name,$password);
mysql_select_db($database) or die( "Unable to database"); 

$query = "Select username from  login Where username = '$username'";
$result=mysql_query($query) or die (mysql_error());
if (mysql_num_rows($result)>0){
print "That Username is already in use";
exit();
}
   }
