while loop php same page search pagination

[ej.p.lopez]

hi everyone
can anyone give me a coad for the form of search inside the php i mean they belong in the same page ?

here's my php command for the pagination and results

//Count the total number of row in your table*/
$count_query   = mysql_query("SELECT COUNT(personid) AS numrows FROM persons");
$row     = mysql_fetch_array($count_query);
$numrows = $row['numrows'];
$total_pages = ceil($numrows/$per_page);
$reload = 'index.php';
//main query to fetch the data 
$query = mysql_query("SELECT * FROM persons ORDER by RAND() LIMIT $offset,$per_page");
//loop through fetched data
while($result = mysql_fetch_array($query)){
$id = $result['PersonID'];
echo "<div class= content > ";
echo"<img height=100 width=100 src='upload/". $result['Image'] ."'/>";
echo "<font color='black'>". $result['FirstName']. "</font></br>";
echo "</div>";

i have this query

// basic SQL-injection protection
$searchText = htmlspecialchars ($_POST['searchText']);

// query with simple search criteria
$query = mysql_query("SELECT * FROM persons WHERE FirstName LIKE '%" 
           . $searchText . "%' ORDER by RAND() LIMIT $offset,$per_page");
