PHP - Php While + Template Engine?

I want to know how to display results from mysql database by filling in a form. but i have found a tutorial which shows typing in a text box which displays results. if i follow this tutorial will it help me to understand and create php coding to display results for my form?

I thinking about building a search engine just as a fun project and a way to develop my skills.  However I'm not sure where to start... 

I want it to be a comparison search engine for computer parts so say the user type in "RAM" it would display results from PC World, Ebuyer, etc.  I was thinking of using cURL but how do I know where the search results are on each page.  For example say  I get a html page of results from PC World and store them in a variable how do I then know what to strip out to get the results I want?  Would I just have to look at the source code?  Also would I then have to work this out for each site I wanted to search from and have a different method of getting the results from search site?

If anyone has done anything like this in the past and could give me some advice that would be great. 

Thanks

Hi, I have a script which searches the MySQL database. It outputs the result which is a business name, but I need the business name to be in a link so the user can click on it and go to another page to find out more information. However the business name is not included in the link, but the $value is.   Here is my script

<?php
include 'init.php';

// normal search
$result_tb = "";
if (!empty($_POST['SEARCH']) && !empty($_POST['search_value'])) {

   $e = $_POST['search_value'];

   $query = 'SELECT aquaticCenterName FROM reviews WHERE ' .
           "aquaticCenterName LIKE '%$e%' OR " .
           "town LIKE '%$e%' OR " .
           "county LIKE '%$e%' OR " .
           "country LIKE '%$e%' OR " .
           "rating LIKE '%$e%' ";

   $query_result = $con->query($query);

 $result_tb = '<div>';
   while ($rows = $query_result->fetch_assoc()) {
      foreach ($rows as $k => $v) {
         $result_tb .= '<a href="reviewResults.php?aquaticCenterName= . $v . ">' . $v . '</a><br>';
      }
   }
   $result_tb .='</div><hr>';

   $con->close();
}
?>
<?php
include 'includes/overall/header.php';
include 'includes/logo.php';
?>
      <form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
         <table>
            <tr>
               <td>
                  <input type="text" name="search_value" size="30" maxlength="30"/>
               </td>
               <td>
                  <input type="submit" name="SEARCH" value="Search"/>
               </td>
            </tr>
         </table>
      </form>
      <?php echo $result_tb; ?>
<?php
include 'includes/overall/footer.php';

But when I click on the link, I get this in the address bar   reviewResults.php?aquaticCenterName=%20.%20$v%20.   How do I get this to read   eg, reviewResults.php?aquaticCenterName=PaulsAquaticCenter   Many Thanks   aquaman  

I'm in the process of build a network and need to create a search that lets people search by both first and last names. I have tailored the code below to search for first names, but I don't know how to tailor it to search for both first and last names.

Code: [Select]


<?php

//get data
$button = $_GET['search'];
$search = $_GET['search'];

if (!$button)
        echo "You didn't submit a keyword.";
else
{
        if (strlen($search)<1)
                echo "Search term too short.";
        else
        {
                echo "You searched for $search<hr>";
               
                require('connect.php');
                       
                        //explode our search term
                        $search_exploded = explode(" ",$search);
                       
                        foreach($search_exploded as $search_each)
                        {
                                //contruct query
                                $x++;
                                if ($x==1)
                                        $construct .= "firstname LIKE '%$search_each%'";
                                else
                                        $construct .= " OR firstname LIKE '%$search_each%'";
                        }
               
                //echo out construct
               
                $construct = "SELECT * FROM users WHERE $construct";
                $run = mysql_query($construct);
               
                $foundnum = mysql_num_rows($run);
               
                if($foundnum==0)
                        echo "No results found!<p>";
                else
                {
                        echo "$foundnum results found!<p>";
                       
                        while ($runrows = mysql_fetch_assoc($run))
                        {
                       
                        //get data
                        $firstname = $runrows['firstname'];
                        $lastname = $runrows['lastname'];

Hello,

I would like to build a php search engine against a mysql database. I am looking for a tutorial but haven't been able to find any good ones. Any ideas of where I can find one? I need one where I can search with several words and if it has the stemmer.class.inc and so on would be great also.

thanks, df

Hi Everyone.
 Am about to create a search engine for my project using php and mysql. My question is that > Do i have to keep creating tables and entries in the  database to contain all the topics to be searched for? Or is there another way to go about it? cos i dont think i can really enter all the search topics and their web address and also their keywords.   
Thank You.

Ok, I have the code below and it only searches one keyword of my database please could you tell me how I can search multiple keywords?

Thanks Please help Soon!

Hi, I'm having two issues with my Search engine for my website. It is created to search through my database (it doesn't crawl through pages). The first problem I'm having is when I type in for example:
Super Mario Bros
and there is a row in my table with a field called Super Mario Brothers
this row is not included as a successful result to the search. I need to somehow modify my code to search every word in every table cell in the database.

So another example. I have 5 rows, each with one cell, named as follows:
One
Two
Three
Four
Five
If I was to type in the search box:
One Two Three Four Five
it should display all rows (it obviously doesn't do that right now lol)

The second issue has to do with my sql query.
It looks like this:

$query = "select * from sheets where artist like \"%$trimmed%\" OR title like \"%$trimmed%\" 
  order by artist"; 
 $numresults=mysql_query($query);

I need this query to search in the columns artist and title (like it is doing above) AS WELL as search only those rows that have an active status set to 'yes'.
I tried to type something like:
$query = "select * from sheets where active='yes' && artist like \"%$trimmed%\" OR title like \"%$trimmed%\" 
  order by artist"; 
but this obviously causes problems. How do i require the query to include rows that are active, but have it look through artist OR title as well?

Here is my code below. Any insight appreciated. Will be working on it til someone is available. Thanks

<?php
  include_once('inc/functions.php');
  // Get the search variable from URL

  $var = @mysql_safe($_GET['q']) ;

Good evening,

I am a newbie when it comes to programming, and I am yet learning. With several help from this forum, and other websites, I am able to finish my very first PHP project. It worked fine, as well as the search engine. However, it is foreseen that the application will be utilizing huge amount of data which would require pagination when viewing. And so I found a tutorial from php freaks as well. However, after I integrated the codes from my web application, the search engine suddenly stopped working. It is still, when I leave the field blank, which would display all data. However, if I type down a search query on the field, it still displays all data. Can anyone help me on this? Here's my complete code:

<link href="add_client.css" rel="stylesheet" type="text/css">

<?PHP
include("dbconnection.php");

$query = "SELECT * FROM records";


if(isset($_POST["btnSearch"]))

{
$query .= " WHERE last_name LIKE '%".$_POST["search"]."%' OR first_name LIKE '%".$_POST["search"]."%'OR territory LIKE '%".$_POST["search"]."%'OR job_title LIKE '%".$_POST["search"]."%'OR title LIKE '%".$_POST["search"]."%'OR employer LIKE '%".$_POST["search"]."%' ORDER BY territory ASC"  ;

$result = mysql_query($query, $connection) or die(mysql_error());

}
