search database content
hi
i have a application were the user admin will select a key word from the drop down based on the dropdown selection....it should search all the rows in a particular table.the corresponding matching data should get displayed to the admin.
He selects a keyword from the dropdown ?
Well, then, you can simply use,
$query="select * from table where col like '%$value%'"; $value is the selected value of the dropdown.

thanks tat was useful.i want only 10 rows to be displayed in the one page......if the query fetches more than 10 then it should display page wise.......it should display rows in alterative colors
<?php
$industype=$_REQUEST['industype'];
$careerlevel=$_REQUEST['careerlevel'];
// how many rows to show per page
$rowsPerPage = 1;
// by default we show first page
$pageNum = 1;
// if $_GET['page'] defined, use it as page number
if(isset($_GET['page']))
{
$pageNum = $_GET['page'];
}
// counting the offset
$offset = ($pageNum - 1) * $rowsPerPage;
// $query = "SELECT val FROM randoms LIMIT $offset, $rowsPerPage";
// $result = mysql_query($query) or die('Error, query failed');
$hostname = "localhost";
$username = "";
$password = "";
$dbid = "";
$link=mysql_connect($hostname, $username, $password);
mysql_select_db($dbid) or die("unable to connect");
$query="(select * from post_resume where ind_type='$industype' and career='$careerlevel' LIMIT $offset, $rowsPerPage)";
$result = mysql_query($query) or die ('Error in query: $query. ' . mysql_error());
echo "";
if (mysql_num_rows($result) > 0)
{
$i=0;
while($row = mysql_fetch_row($result))
{
echo "";
echo "".$row[2]."";
echo "Job Type ".$row[4]."";
echo "Highest Degree ".$row[5]."";
echo "Owner ".$row[8]."";
echo "";
$i++;
}
echo $i;
echo "";
}
// print the random numbers
while(list($val) = mysql_fetch_array($result))
{
echo "$val
";
}
echo '
';
// how many rows we have in database
// $query = "SELECT COUNT(val) AS numrows FROM post_resume";
// $result = mysql_query($query) or die('Error, query failed');
// $row = mysql_fetch_array($result, MYSQL_ASSOC);
// $numrows = $row['numrows'];
$numrows = $i;
// how many pages we have when using paging?
$maxPage = ceil($numrows/$rowsPerPage);
$self = $_SERVER['PHP_SELF'];
// creating 'previous' and 'next' link
// plus 'first page' and 'last page' link
// print 'previous' link only if we're not on page one
if ($pageNum > 1)
{
$page = $pageNum - 1;
$prev = " [Prev] ";
$first = " [First Page] ";
}
else
{
$prev = ' [Prev] ';
// we're on page one, don't enable 'previous' link
$first = ' [First Page] ';
// nor 'first page' link
}
// print 'next' link only if we're not
// on the last page
if ($pageNum < $maxPage)
{
$page = $pageNum + 1;
$next = " [Next] ";
$last = " [Last Page] ";
}
else
{
$next = ' [Next] ';
// we're on the last page, don't enable 'next' link
$last = ' [Last Page] ';
// nor 'last page' link
}
// print the page navigation link
echo $first . $prev . " Showing page $pageNum of $maxPage pages " . $next . $last;
mysql_close($link);
?>
// how many rows to show per page
$rowsPerPage = 1;
change the $rowsPerPage to how many rows you want to display,ok?
tat part is working perfectly.but when i wantto switch to the next page....the page links are not working
2 dropdown...when data is selected it will search
<html>
<head>

<body>
<form method="post" action="paging.php" >

<td>
<select name="industype">
