Need Help With Search Query

[john-formby]

Hi,

I have a mysql database and want to be able to search and return results. I found an example online and have been trying to adapt it but it will not show the results. I don't know what is wrong so I would be really grateful if someone could help me out.

Here is the table:

[code]CREATE TABLE `links` (
  `link_id` int(11) NOT NULL auto_increment,
  `category_code` varchar(10) NOT NULL default '0',
  `link_text` varchar(254) NOT NULL default '',
  `url` varchar(254) NOT NULL default '',
  `description` text NOT NULL,
  `keywords` text NOT NULL,
  `time_added` timestamp(14) NOT NULL,
  `new_window` tinyint(4) NOT NULL default '0',
  PRIMARY KEY  (`link_id`)
) TYPE=MyISAM AUTO_INCREMENT=234;[/code]


Here is the search form:

[code]Search<br />
<form name="search" method="post" action="srch.php">
<input type="text" name="find" size=16 maxlength="255"><br />
<input type="hidden" name="searching" value="yes" />
<input type="submit" name="search" value="Search" />
</form>[/code]


Here is the form processing:

[code]<?
include("common/navigation.php");
?>
            <td width="560px"><h1>Search Results</h1>

<?
//This is only displayed if they have submitted the form
if ($searching =="yes")
{

//If they did not enter a search term we give them an error
if ($find == "")
{
echo "<p>You forgot to enter a search term";
exit;
}

// Otherwise we connect to our Database
mysql_connect("localhost", "USER", "PASS") or die(mysql_error());
mysql_select_db("pagelinks") or die(mysql_error());

// We preform a bit of filtering
$find = strtoupper($find);
$find = strip_tags($find);
$find = trim ($find);

//Now we search for our search term, in the field the user specified
$data = mysql_query("SELECT * FROM links WHERE upper($keywords) LIKE'%$find%'");

//And we display the results
while($result = mysql_fetch_array( $data ))
{
echo $result['link_text'];
echo " ";
echo $result['description'];
echo "<br>";
echo $result['url'];
echo "<br>";
echo "<br>";
}

//This counts the number or results - and if there wasn't any it gives them a little message explaining that
$anymatches=mysql_num_rows($data);
if ($anymatches == 0)
{
echo "Sorry, but we can not find an entry to match your query<br><br>";
}

//And we remind them what they searched for
echo "<b>Searched For:</b> " .$find;
}
?>[/code]

I have the word HTML in the keywords row of all of the links, yet when I try to search for it the following message just comes up:

Sorry, but we can not find an entry to match your query

Searched For: HTML


Thanks,

John

you don't need to upper case trouble. Unless you tell it not to, Mysql compare string in case-insensitive by default.


change your query like this:
$data = mysql_query("SELECT * FROM links WHERE keywords LIKE '%$find%'");
