PHP - Search In Files

Hello,

Does anyone know a tutorial I can follow to create my own search engine over the items I have in my SQL database?
I find a lot of tutorials but they are all 'one word searches' which means if you type two words you will get all results that contain either word (too many hits).

If the search engine tutorial displays result with AJAX even better.

Thanks for help.

Friends,

I want to extract the Search Keyword from the URL, a visitor came from. I am using a PHP CMS and want to show the Keyword on my Blog.

So if they search "abcd" from google, i want to extract "abcd" and echo on my blog.

Here is the coding i could got hold of, but its not working, not echoing anything

<?php

Hello. I am working on a php script for searching a database table. I am really new to this, so I used the this tutorial http://www.phpfreaks.com/tutorial/simple-sql-search

I managed to get all the things working the way I wanted, except one important and crucial thing.
Let me explain.
My table consist of three columns, like this:

ID(bigint20)    title(text)        link (varchar255)
=============================
ID1                title1                link-1
ID2                title2                link-2
etc...

Like I said, I managed to make the script display results for a search query based on the title. Want I want it to do more, but I can't seem to find the right resource to learn how, is to place a "Download" button under each search result with its corresponding link from the table.

Here is the code I used.

<?php

$dbHost = 'localhost'; // localhost will be used in most cases
// set these to your mysql database username and password.
$dbUser = 'user'; 
$dbPass = 'pass';
$dbDatabase = 'db'; // the database you put the table into.
$con = mysql_connect($dbHost, $dbUser, $dbPass) or trigger_error("Failed to connect to MySQL Server. Error: " . mysql_error());

mysql_select_db($dbDatabase) or trigger_error("Failed to connect to database {$dbDatabase}. Error: " . mysql_error());
// Set up our error check and result check array
$error = array();
$results = array();
// First check if a form was submitted. 
// Since this is a search we will use $_GET
if (isset($_GET['search'])) {
   $searchTerms = trim($_GET['search']);
   $searchTerms = strip_tags($searchTerms); // remove any html/javascript.
   
   if (strlen($searchTerms) < 3) {
      $error[] = "Search terms must be longer than 3 characters.";
   }else {
      $searchTermDB = mysql_real_escape_string($searchTerms); // prevent sql injection.
   }
   
   // If there are no errors, lets get the search going.
   if (count($error) < 1) {
      $searchSQL = "SELECT title, link FROM db WHERE title LIKE '%{$searchTermDB}%'";

      $searchResult = mysql_query($searchSQL) or trigger_error("There was an error.<br/>" . mysql_error() . "<br />SQL Was: {$searchSQL}");
      
      if (mysql_num_rows($searchResult) < 1) {
         $error[] = "The search term provided {$searchTerms} yielded no results.";
      }else {
         $results = array(); // the result array
         $i = 1;
         while ($row = mysql_fetch_assoc($searchResult)) {
            $results[] = "{$row['title']}<br /> Download - this is the button I want to link to the title results - and maybe other links too - <br /> ";

    $i++;

       

   
         }
      
      }
   }
}

function removeEmpty($var) {
   return (!empty($var)); 


}
?>

      <?php echo (count($error) > 0)?"The following had errors:<br /><span id=\"error\">" . implode("<br />", $error) . "</span><br /><br />":""; ?>
      <form method="GET" action="search?" name="searchForm">
         Search for title: <input type="text" name="search" value="<?php echo isset($searchTerms)?htmlspecialchars($searchTerms):''; ?>" />
        
         <input type="submit" name="submit" value="Search" />
      </form>

    <?php echo (count($results) > 0)?"Rezultate lucrari de licenta sau disertatie pentru {$searchTerms} :<br /><br />" . implode("", $results):""; ?>




 $results = array(); // the result array
         $i = 1;
         while ($row = mysql_fetch_assoc($searchResult)) {
            $results[] = "{$row['title']}<br /> Download - this is the button I want to link to the title results - and maybe other links too - <br /> ";

    $i++;

 
I would like the results to be displayed like this

Results for SearchItem:

Result 1
Download | Other link
Result 2
Download | Other link
etc.... or something like this.

So, how do I add the data from the link row into a text(Dowload), within an <a href> tag (well, at least I guess it would go this way) ?
My first tries (fueled by my lack of knowledge) where things like

$results[] = "{$row['title']}<br /> <a href="{$row['link']}">Download</a> <br /> ";

but I keep getting lots of errors, and then I don't know much about arrays and stuff (except basic notions);
So there it is. I am really stuck and can't seem to find any workaround for this.
Any suggestions? (examples, documentation, anything would do, really)
Thanks,
Radu

I am developing a intranet forum in Php and MySQL and I am using ajax to display searched results on the same page but right now I am using query LIKE text% to search in database which is slower. but I want to make it fast search engin which can parse *,+ and show result.

Since I am using ajax i am not able to use free search engin,so if possible pls provide a complete solution

Hi all

How do I modify the below code to search multiple tables in mySQL database?

$query = "select * from store_items where description like \"%$trimmed%\"  or title like \"%$trimmed%\" or dimensions like \"%$trimmed%\" order by id ASC";

 $numresults=mysql_query($query);
 $numrows=mysql_num_rows($numresults);

It is for a search function and I need it to search another table called 'about_text' and 'faq_text'

Thanks
Pete

Hello,

I'm developing a website that asks the user to submit a keyword for a search. The results should display matches for this keyword, but also show matches for related keywords (in order of relevenace!).

I'm planning on building up a library of which search terms users use in the same sessions (e.g. if someone searches for "it jobs" and "php jobs", I'll know the terms are correlated), and I'll also measure the click-through rates of the items on the results list.

I've been spending all weekend trying to map out the design for this but it's proving incredibly complicated and I think the solution is likely to be on the internet somewhere already?!

Please could someone point me in the right direction if you've come accross this problem before?

Thanks a million,

Stu

I have code to search a database of members, I can search by lastname but having a little problem. I want to be able to search by lastname starting with the first letter. (ie:  a or b or c or d and so on). As it is right now I can only search by first letter of last name if I add % to the search (ie: a% b% c%) will give me all members with the last names starting with the approiate letter designation. I'm not sure how to handle this, any help would be appreciated. Thanks.

Hello All,

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?

Need some help I have 2 tables in a database and I need to search the first table and use the results from that search, to search another table, can this be done? and if it can how would you recommend that I go about it?

Thanks For Your Help Guys! 

first of all...its good to see the site back .   my question guys is i'm wondering is there a way of getting the column number when reading a .cvs file? ie. a, b, c, d, aa, ab etc?

$row = 1;
if (($handle = fopen($file, "r")) !== FALSE) 
{
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) 
    {
        $num = count($data);
        echo "<p> $num fields in line $row: <br /></p>\n";
        $row++;
      
        for ($c=0; $c < $num; $c++) 
        {
            //echo $data[$c] . "<br />\n";
        }
    }
    
    fclose($handle);
}

now $num counts the columns...but i want to convert that into a alphabetical column...is there a easy solution?   thanks guys

lets say I own a file, and you own a file,  both these files are the exact same file, the only difference is the filename. So lets say we both have The Gimp 2.6 but one is named TG2.6.exe and the other is named the_Gimp-2.6.exe. What would be the best way to count the files that are the same even if they have a different file name? Another example would be:

I have a file called me.jpg and someone else has a file me.jpg but they are two completely different pictures. What would I do to tell that?

Hey,

Trying to learn to generate PDF files, something apparently WAAAAYYY more complex than I thought. Can someone please give me an explanation on '$optlist' from this function.....

PDF_load_image  ( resource $pdfdoc  , string $imagetype  , string $filename  , string $optlist  )

What is it? PHP.net doesn't have any info at all.

Thanks,
IceKat.

BTW - Any (recent) tutorials or pages would be appreciated. Everything I find is out of date or doesn't work.

I have told that the php files I was working on contains BOM by default cause of the editor I m using. I have installed other editor that can create php files without BOM.

So my question is  what's the difference between 2 files, one with BOM and other without BOM ? Any problems I may face for long term usage ? Which one is better to use ?

im trying to make a program that changes some files from 0 to 1,but im having some trouble...

heres my code,
Code: [Select]
$id = $_GET["id"];

$file1 = "http://mysite.co.cc/users/".$id."/file1.txt";

$fh = fopen($file1, 'w');
fwrite($fh, "1");
fclose($fh);

I followed this tut: http://www.tizag.com/phpT/filewrite.php

I cant find anything wrong with the code,but it will not make the file have 1 in it.
