Topic: txt file search program needed

[Flustered]

I need a search engine for a web site that will search a .txt file and return each line as a result. I used a program called Search Engine Builder Pro v2.02, that came close, but it detects the .txt file as one big result, it doesn't read each line as a result. Any ideas? Thanks all!

P.S. If needed, I could put up a temp web site that would show what I have so far and what isn't working

P.S.S. I am an idiot on any scripting, so please make any answers in a manner that a 6 yr old would understand...lol (and sorry for any offense to 6 yr olds that may read this)

[wildteen88]

Post some example data from the text file and the result you'd like.

[Flustered]

Below are some lines from the type of txt. What I need is is you searched for "Followers", it would return 2 results (as I duplicated the line). What I have now, just shows the entire .txt as 1 result. If it finds the search word, I need it to return as a result, the entire line it is in as 1 result. For example:
Found 1 result:
Followers of the Unification Church are called ________*Moonies
Found 2 result:
Followers of the Unification Church are called ________*Moonies

I think it would need some way to block certain searchs, like single letters or numbers, so it doesn't go crazy

Something like this:

Code: [Select]

<?php

function search($keyword)
{
    $results = false;
    $lines   = file('search_data.txt');

    // escape characters which are sensitive to eregi()
    $symbols = array('[', ']', '-', '(', ')');
    $replace = array('\[', '\]', '\-', '\(', '\)');
    $keyword = str_replace($symbols, $replace, $keyword);

    foreach($lines as $line)
    {
        if(eregi($keyword, $line))
        {
            $line = str_replace($keyword, "<b>$keyword</b>", $line);
            $results[] = $line;
        }
    }

    return $results;
}

if(isset($_POST['submit']))
{
    if(!empty($_POST['keyword']) && strlen($_POST['keyword']) > 3)
    {
        $keyword        = $_POST['keyword'];
        $search_results = search($keyword);

        if(is_array($search_results))
        {
            echo 'The search term "<i><b>'. $keyword . '</b></i>" found ' . count($search_results) . ' search result(s):';

            echo '<ol><li>' . implode('</li><li>', $search_results) . '</li></ol>';
        }
        else
        {
            echo 'No results was returned';
        }
    }
    else
    {
        echo 'Invalid search term "<i><b>'. $_POST['keyword'] . '</b></i>"';
    }
}

?>

    Search word: <input type="text" name="keyword" /> <input type="submit" name="submit" value="Search" />
</form>search_data.txt is the file which contains your search data.

[Flustered]

I'm getting an error, as this part of the code shows on the webpage and also I'm guessing its stopping any results from showing:

Code: [Select]


3) { $keyword = $_POST['keyword']; $search_results = search($keyword); if(is_array($search_results)) { echo 'The search term "'. $keyword . '" found ' . count($search_results) . ' search result(s):'; echo '

' . implode('
', $search_results) . '
'; } else { echo 'No results was returned'; } } else { echo 'Invalid search term "'. $_POST['keyword'] . '"'; } } ?>



Thanks so much for helping!

[wildteen88]

Huh, don't understand you there, why is the code in one line? What errors are you getting? If code is being displayed then something is wrong with your PHP installation.

[Flustered]

when I put that code on a html page, I see Search Word: and the search box, but above that I see the above part of the code in text on the page

[wildteen88]

You need to save the code within a .php file and not a .html file. Make sure your hosting account supports php.

[Flustered]

sorry I'm so dense, but what do I need to add to html page to link to this?

[wildteen88]

As in a hyperlink?

Code: [Select]

<a href="search.php">Search</a>Or type go to it manually:
http://yoursite.com/search.php

Change search.php to the name of your actual .php file.

[Flustered]

not as a hyperlink, I mean I don't have the search box showing on the html page

[wildteen88]

If you want the search box on the html page then you can copy the form code over to your html page, set the action attribute in the form tag to search.php, eg:

Code: (search.html) [Select]

<form action="search.php" method="post">
    Search word: <input type="text" name="keyword" /> <input type="submit" name="submit" value="Search" />
</form>When the form is submitted the browser will load search.php displaying the results.

[Flustered]

Thanks so much for the help, with a bit of luck, I can get this working now!!

It's working pretty good now, but I had a question on a couple small issues. Can it be adjusted to search for more than one word?  And when you enter the search word and hit enter, it doesn't work, you have to use the mouse to click the button. Is this an easy issue to fix?

[wildteen88]

It certainly can, all you need to do is call the search() function fo each keyword entered in the search box.

And when you enter the search word and hit enter, it doesn't work, you have to use the mouse to click the button. Is this an easy issue to fix?

You'll need to use Javascript for that.

[Flustered]

sorry I'm so dense on this, but I don't quite understand what you mean by:

Can you give me an example or something?  Thanks

[Flustered]

can it be modified to search for words more at random? I noticed that if you had a line of <one two three>, it would search and find "one two" and "two three", but no results if search was for "one three". Also because of the format of data, there are dots and astericks, so if the data line was <one.two*three>, there would be no results for searching "one two". I really appreciate the time and effort in helping with this, as I get totally lost.

[wildteen88]

Hi, sorry I haven't replied. I have modified the script a little to how I think you wanted:

Code: [Select]

<?php

    global $keyword_count;

    $lines   = file('search_data.txt');
    $results = false;

    $symbols = array('[', ']', '-', '(', ')');
    $replace = array('\[', '\]', '\-', '\(', '\)');

    $colors  = array('#FF0000', '#0000FF', '#00FF00', '#FFFF00');

    $i = 0;
    foreach($lines as $line)
    {
        $keyword_found = false;

        foreach($keywords as $key => $keyword)
        {
            if(!isset($keyword_count[$keyword]))
            {
                $keyword_count[$keyword] = 0;
            }

            $keyword = str_replace($symbols, $replace, $keyword);

            if(eregi($keyword, $line))
            {
                $keyword_found = true;

                // remove answer from end of line
                $line = eregi_replace("\*([a-z0-9 ]+)", '?' , $line);
                $line = str_replace($keyword, "<span style=\"color: {$colors[$key]}; font-weight: bold;\">$keyword</span>", $line);

                $results[$i] = $line;

                $keyword_count[$keyword]++;
            }
        }

        if($keyword_found)
            $i++;
    }

    return $results;
}

There is no need for you to apologize, your help has been so greatly appreciated. I feel bad that I am so ignorant that I have to ask for so much help. The change doesn't seem to work however. It shows  1 blank result for each multi-word try. i.e.

The keywords "one three" found 1 result(s):

1.

Single word search still works

[wildteen88]

Bug fixed, forgot to add some in. Try:

HTML

Code: [Select]

<form action="search.php" method="post">
    Keywords:<br /><textarea name="keyword" cols="40" rows="4"><?php echo isset($_POST['keyword']) ? $_POST['keyword'] : null; ?></textarea>
    <p><input type="submit" name="submit" value="Search" /></p>
</form>Also note that I changed the search box to a textarea rather than a text field so you'll need to modify your search box HTML code to the HTML code posted above. When performing a search you now place each keyword on a separate line within the Keywords search box rather than a space.

[Flustered]

sorry for delay, its real close, but there is one thing that would be better. On the multiple word search, it searches for either, and would be a lot better if it only searched for both (or multiple). For example, if you searched for "one" and "two" in search box, it shows all results with either word, instead of narrowing the search to only ones with both words.

Again, I want to thank you for the help and effort!!

[wildteen88]

Umm not quite getting you. From my testing my code does this are you using my updated PHP and HTML code? Each search word must go on a separate line(rather than separated by a space) in the textarea.

[Flustered]

What I was trying to say was if you search for multiple words, it gives results of any one word in different colors, but can be a large result page. I was wondering if it could be changed so it only gave results that only contained all of the search words used.

So if you had the following lines in the data and searched for "one two"(on separate lines), only the "one two three" line would  be a result

one two three
one three four
one three five

Currently it would show all three lines as a result with "one" in red, and "two" in blue

For the webmasters working with this script...Do you know a solution for next "problem"?

My text file contains something like this (example is just a copy from Wikipedia):

Line (geometry), an infinitely-extending one-dimensional figure that has no curvature
a length of rope, cable or chain when put to use (such as a clothesline, anchor line)
a line or queue of people waiting in a queue area
a line of text in writing

When I search for 'figure', I get 'Line (geometry), an infinitely-extending one-dimensional figure that has no curvature' (cool!)

When I search for 'that has no curvature', I get 'Line (geometry), an infinitely-extending one-dimensional figure that has no curvature' (cool!)

BUT when I search for 'figure curvature', I get NOTHING. So this script is search for the exact match.

Is there a way to tell this script to show the lines with 'figure' and 'curvature' in the same line?

[wildteen88]

If you're using this version here
Then enter each word to search for on a separate line.

[nicob]

If you're using this version here
Then enter each word to search for on a separate line.

Yes, I'm using that version. But now I understand why I didn't understand that part of search:
- When you have let's say 10 lines with 'figure' and 'curvature' not all words get a red or blue color (when on the same line, in some cases only one word gets a color).
- Because I'm using GET (and not POST) I see an url like .../search.php?keyword=figure%0D%0Acurvature&submit=Search. I expected '+'.

I have tested out alot of search-in-files-script, but this is the best: simple to use, great options, and no database required

Some technical questions for coders:
1. How do you convert '%0D%0A' to '+' in the url?
2. I'm trying to include the result in a page in a local format

Code: [Select]

<?php include "/home/account/domains/domain.com/public_html/search.php?keyword=garden&submit=Search"; ?>
but this is not working, so now I'm using fopen to reach the same result. But I have to use 'http'. Is there a solution for this?
3. is it possible to remove '&submit=Search' from the output url?
