Hi,

I am not that good with understanding REGEX/REGEXP functions but,
Could someone please let me know as how can I search through html code for a particular tag having a definite start and definite end.

E.g. HTML Code below, it has

 definite Start of Code: [Select]
<div id="ST
 and definite End of Code: [Select]
house='Anything'></div></div></div>
Code: [Select]
<div id="ST12345678_st" class="r_right_col">
<div class=""></div>
<div id=""><span class=""></span></div>
<div class=""></div>
<div class=""><span class=""></span></div>
<div class=""></div>
<div class="">
<div style="" id=""
fname=Abhishek
lname='madhani'
division=8C
house='Anything'>
</div>
</div>
</div>
So the HTML file which I have, has the this particular tag being repeated atleast more than 50 times in whole code.

And I am planning to extract each of them seperately. So if someone could help me with REGEX to search for this particular tags in whole file, would be really helpful.

Abhishek Madhani

Hey all,
Wondering maybe someone can help me out, I am training to be a firefighter (I am not a coder) and am writing a little script for my local volunteer fire brigade to try help em out a little and I am stuck! It doesn't do much but grab the address out of a pager message but I have searched and tried a few ways to get this and now I am tired and just can't get my head around how to do this! Let me explain,

Below are 2 pager alert messages and I have a sore head of a time trying to extract the address and job details of the second message into a php string using Expressions/Regex...

Here are 2 example messages:

Code: [Select]
0571040 15:45:21 30-04-12  @@ALERT F546356345 THEB8 STRUC1 SMELL OF SMOKE AND ALARM OPERATING 900 SOME ROAD SOMESUBURB /CROSSSTREET1 RD //CROSSTREET2 AV M 99 A1 (429085) CTHEB CBOROS PT28 [THEB]

0571040 15:45:21 30-04-12  @@ALERT F546356345 THEB8 STRUC1 SMELL OF SMOKE AND ALARM OPERATING 4 / 900 SOME ROAD SOMESUBURB /CROSSSTREET1 RD //CROSSTREET2 AV M 99 A1 (429085) CTHEB CBOROS PT28 [THEB]
You will note the second address has 4 / 900 at the start or it could say Unit 4 / 900... and this is where my issue starts! The addresses can come in the 2 different formats, I have first one sorted with the code below but this address with no 4 / 900 some road just has me and my code below stumped. The extra / is just to complex a thing for me and my brain to handle! lol Please Help!

As you can see I use the first slash as the first cross street but in the second case above the first / is now a part of the address... Below is what I have so far:

Code: [Select]
function get_string_between2($string, $start, $end){
    $string = " ".$string;
    $ini = strpos($string,$start);
    if ($ini == 0) return "";
    $ini += strlen($start);
    $len = strpos($string,$end,$ini) - $ini;
    return substr($string,$ini,$len);
}

$fullstring = "$rawPage";

if ( strpos($fullstring, ' STRUC1 ')!== false )
{
$parsed = get_string_between2($fullstring, "STRUC1", "/");
}
$input = "$parsed";
preg_match('/([^0-9]+)(.*)/', $input, $matches);

$jobdet = "$matches[1]";

$jobadd = "$matches[2]";
Now this works fine for the top message and I get this as the result:

$jobdet =  SMELL OF SMOKE AND ALARM OPERATING

$jobadd =  900 SOME ROAD SOMESUBURB

$firstcrossstreet = /CROSSSTREET1 RD

$secondcrossstreet = //CROSSSTREET2 AV
For the second message it's all wrong with this the result:

$jobdet =  SMELL OF SMOKE AND ALARM OPERATING

$jobadd =  4

$firstcrossstreet = / 900 SOME ROAD SOMESUBURB /CROSSSTREET1 RD

$secondcrossstreet = //CROSSSTREET2 AV
I know it's the / causing it but how can I make the code handle either case?

Any help would be greatly appreciated!
Thanks!

 The result pages is supposed to have  pagination like google  help me please

 

I require a page to be added to my website. This page will facilitate a refined search via Google, Bing and Yahoo search engine simultaneously , show the top 5 of each engine.

Is this possible using php ?

Thank's

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.

I am trying to check my youtube code value and see if &amp;rel=0 has been added to it and if not added it. I suck at regular exp can someone help?

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.

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

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

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

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.

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

Hey

I'm pretty new to regular expression, so I might have made a silly mistake. I want to check if there are any symbols/special characters (not letters or numbers) in a string. I have the code below.


function validateKeywords($kw) {
if (preg_match("/[^A-Za-z0-9]/", $kw)) {
echo 'validation of keywords failed<br />';
return false; // String contains symbols (not letters or numbers) - incorrect format!
}
else {
echo 'validation of keywords succeeded<br />';
return true; // Correct format
}
}

// Testing
validateKeywords('some random string I wrote for testing purposes'); // should succeed
validateKeywords('some random 10 string I wrote for testing purposes 2010'); // should succeed
validateKeywords('some random, string, I wrote for 19 testing purposes'); // should fail
validateKeywords('some, random, string I wrote, for testing purposes'); // should fail


The problem is that all 4 calls return false and print that the validation failed. So, where did I mess up?

Thanks!
