Help with search results

cs1h · October 11, 2007

Hi,

I have a script that is designed to perform a search and then show the results in pages of 5 results each but I am getting an error and I don't know how to solve it. Can anyone help?

The error is,

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in D:\Inetpub\vhost\myroho.com\httpdocs\alimit2.php on line 137

And the script is,

<?php



$host = "localhost"; //your sql host, usually 'localhost'

$user = "xxx"; //username to connect to database

$pass = "xxx"; //password to connect to database

$db = "xxx"; //the name of the database

$targetb = $_POST['menuFilesDMA'];
$targetb = str_replace(' ','_', $targetb);

mysql_connect($host,$user,$pass) or die("ERROR:".mysql_error());

mysql_select_db($db) or die("ERROR DB:".mysql_error()); 





$max = 5; //amount of articles per page. change to what to want

$p = $_GET['p'];

if(empty($p))

{

$p = 1;

}

$limits = ($p - 1) * $max; 

//view the news article!

if(isset($_GET['act']) && $_GET['act'] == "view")

{

$targetb = mysql_real_escape_string($targetb);

$type = mysql_real_escape_string($_POST['Type']);

$keywords = preg_split("/[\s,]+/", trim($_POST['keyword']));
$keys = "";
foreach($keywords as $K)
{
$keys .= "AND (Abstract LIKE '%$K%' OR town LIKE '%$K%')";
}

$sql = "SELECT * FROM items WHERE (country='$targetb' OR continent='$targetb') AND (type='$type' OR alltype='$type') $keys ORDER BY id DESC";

while($r = mysql_fetch_array($sql))

{

$Country = $row['country']; 
$Type = $row['type'];
$More = $row['id'];
$Title = $row['Title'];
$Abs = $row['Abstract'];

Any help will be much appriciated,

Thanks

You haven't executed your query... You gave the sql string to mysql_fetch_array().

So before:

while($r = mysql_fetch_array($sql))

You need to add:

$sql = mysql_query($sql);

Thanks that removed that error but I am now getting no results, the page just comes up with

Title Author

on it.

Any ideas why this may be,

Thanks Colin

Orio · October 11, 2007

Well obviously you have done something wrong in building the query, or simply by the data given there are no matches...

Orio.

kirk112 · October 11, 2007

Where you added

$sql = mysql_query($sql);

change to

$sql = mysql_query($sql) or die(mysql_error());

this will tell you if there are any problems with the sql query

Orio · October 11, 2007

@kirk112- if there was a problem with the query in it's syntax, mysql_query() would have returned false and then mysql_fetch_array() would spit an error that the given argument is not a mysql-object. So there's nothing wrong with the syntax, it's simply a problem of logic- the query is not built correctly.

I am new at this so it may sound stupid, and if i am wrong can someone explain why.

here goes

while($r = mysql_fetch_array($sql))

You haven't defined what $r is. Therefore you are saying while the value of nothing execute the query. You need to define the value of $r.

Orio · October 11, 2007

@adam- this is the syntax that is often being used to over the fetched rows. This is not a problem.
