Hi everyone!!

 

I finish to do my second populating drop down list. it's not realy the display I was looking but for now it will be good. but when I click on my serach button I receive this erro.

 

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in C:\wamp\www\scale24-25\search-keyword.php on line 112

 

this is what line 112 is in the search file.

 

//-create  while loop and loop through result set 

  while($row=mysql_fetch_array($result)){  <--------------  line 112

       

 

here's the code of my form...

 

<?php
include_once("connection.php");

You should be checking for successful query execution and handling any problems. That error is a good indication that the query failed. Echo the query string, and any errors returned.

 

Pseudo-code

$query = "Your query string";
if( $result = mysql_query($query) ) {
     while( $array = mysql_fetch_assoc($result) ) {
          // do stuff for successful query
     }
} else {
     echo "<br>Query string: $query<br>Failed with error: ". mysql_error() . '<br>';
}
