Following search script search for the keywords.
I've got a table called articles(article_id, article_name, article_file, article_keywords)
I search for the keywords and display the article names, its working fine!
I want to highlight these article names so that when i click on the article name, the file name which is under article_file has to be shown.
Could somebody please tell me how can i modify my code further.
Many thanks
Code: Select all
<?php
// Get the search variable from URL
$var = @$_GET['q'] ;
//trim whitespace from the stored variable
$trimmed = trim($var);
// rows to return
$limit=10 ;
// check for an empty string and display a message.
if ($trimmed == "")
{
echo "<p>Please enter a search...</p>";
exit;
}
// check for a search parameter
if (!isset($var))
{
echo "<p>You dont seem to have a search parameter!</p>";
exit;
}
//connect to your database
mysql_connect("localhost","myadmin","");
