ok so I have changed it to the following:

 

Change your PHP to this:

 

<?php

echo $row['value'];

?>

Do I need to change the following?

 

mysql_real_escape_string($result)

 

//or this...

 

while ($row = mysql_fetch_assoc($result)) {

echo $row['value'];

}

 

 

Also could the problem be in the query? Are my quotations correct? Again thanks a million you guys are great!

[displaying a complex mysql query with php]

I have completed my mysql query and it is as follows:

 

SELECT distinct xcart_extra_field_values.value FROM xcart_products, xcart_products_categories, xcart_extra_field_values WHERE xcart_products.productid=xcart_products_categories.productid AND xcart_products_categories.categoryid=314 AND xcart_products.productid=xcart_extra_field_values.productid AND xcart_extra_field_values.fieldid=1 ORDER BY xcart_extra_field_values.value;

 

However I am having difficulty displaying it with php...in fact I am not even sure if I am approaching it correctly (well obviously I am not because it does not work lol)

 

Here is what I have thus far (note: it doesn't work)

 

    <?php 
// Establish DB connection
 $host = "localhost";
 $user = "db_user";
 $pass = "db_pass";
 $dbname = "db_name";

$connection = mysql_connect($host,$user,$pass) or die (mysql_errno().": ".mysql_error()."<BR>");
mysql_select_db($dbname); 

 
// Formulate query
 $query = sprintf("SELECT distinct xcart_extra_field_values.value FROM xcart_products, xcart_products_categories, xcart_extra_field_values WHERE xcart_products.productid='xcart_products_categories.productid' AND xcart_products_categories.categoryid='314' AND xcart_products.productid='xcart_extra_field_values.productid' AND xcart_extra_field_values.fieldid='1' ORDER BY xcart_extra_field_values.value LIMIT 0, 30", mysql_real_escape_string($result));

// Perform Query
$result = mysql_query($query);

// Check result
// This shows the actual query sent to MySQL, and the error. Useful for debugging.
if (!$result) {
  $message  = 'Invalid query: ' . mysql_error() . "\n";
  $message .= 'Whole query: ' . $query;
  die($message);
  }
  
// Use result
while ($row = mysql_fetch_assoc($result)) {
echo $row['result'];
}

// Free the resources associate with the result set
mysql_free_result($result);
?>

 

Now I need to display the results in 2 columns but with the above code I am just trying to display anything period. I have tested the db connection and sql query and they are correct it is just my php that needs some tweaking.

 

I really appreciate any help.

 

Thanks
