I have a database table named with books. it consists of something like below
title | author | category
xyz madman fiction
adapt brainless fiction
adaxx stupid fiction
follow idiot journal
your man acadamic
user is trying to search the value by author or title and based on category
ex: if user search for adapt by selecting fiction need display both adapt and adaxx
below is the code for searching and using mysql database
[code]
<form action=”search.php” method=”post”>
<?php
$select_query= “Select distinct category from books”;
$select_query_run = mysql_query($select_query);
$select_query_array= mysql_fetch_array($select_query_run) ;
$cat = $select_query_array[‘category’];
echo “<select name=’name’>”;
while ($select_query_array= mysql_fetch_array($select_query_run) )
{// dynamic drop list
echo “<option value='”.htmlspecialchars($select_query_array[“category”]).”‘ >”.htmlspecialchars($select_query_array[“category”]).”</option>”;
}
echo “</select>”;
?>
<input type=”text” name=”searchvalue” size=”5″ id=”searchfield” title=”searchfield” onFocus=”clearText(this)”/>
<input type=”submit” name=”submit” value=”” alt=”Search” id=”searchbutton” title=”Search” />
</form>
<?php
$button = $_POST[‘submit’];
$search = $_POST[‘searchvalue’];
if(strlen($search)<=1)
{
$name = $_POST[‘name’];
//echo $a;
echo “Search term too short”;
}
else{
echo “You searched for $search <hr size=’1′></br>”;
$search_exploded = explode (” “, $search);
$x = “”;
$construct = “”;
foreach($search_exploded as $search_each)
{
$x++;
if($x==1)
$construct .=”title LIKE ‘%$search_each%'”;
else
$construct .=”AND title LIKE ‘%$search_each%'”;
}
$construct =”SELECT * FROM books WHERE $construct and category = ‘$name'”;// I tried this but not working
$run = mysql_query($construct);
$foundnum = mysql_num_rows($run);
if ($foundnum==0)
echo “Sorry, there are no matching result for $search.</br></br>1.”;
else
{
echo “$foundnum results found !<p>”;
}
?>
