Question

I have a simple query that is suppose to take user inputted text and find words matching like a search engine. I use jquery’s post function to take this data and send it to a tags.php for processing. However, nothing is echoed out. I think my sql statement may be wrong. im pretty sure my database has keywords that match the input string.

PHP:

$tags=mysql_real_escape_string($_POST['tags']);
$query=mysql_query("SELECT * FROM tags WHERE tag LIKE '%$tags%'");
$num_rows=mysql_num_rows($query);
if ($num_rows == 0){
echo "<div class='result'>No Results</div>";
}
else{
while ($row=mysql_fetch_assoc($query)){
    echo "<div>$row['tag']</div>";
}

}

JQUERY:

$('#tagsInput').keyup(function(){

        var tags = $(this).val();
        if (tags==''){
            $('#tagResult').css("display" , "none");
        }
        else{
            $('#tagResult').css("display" , "block");

                $.post('../tags.php' , {tags: tags} , function(response){

                $('#tagResult').html(response);     
                });
            }
    });

Copy and paste your while loop with this one :

while ($row=mysql_fetch_assoc($query)){
    echo "<div>".$row['tag']."</div>";
}
