PHP - Forum Search Engin To Search Keywords In Database In Php
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 Similar Tutorialshi there - first attempt at programming in PHP so please bear with my novice attempts (not much programming experience in any languege really) i am building a site which hosts mp3s. I have MySQL database with one of the fields contating descriptive keywords for the tracks (such as slow, chilled, intense etc) i have created an html page with search form that send data to php file which runs a query of the keywords field - and all works fine now i want that in addition to the search form (with an input text box for the search criteria and the submit button) i will have a 'cloud' of key words - clickable links - that will send the data to the PHP query file (clicking on slow will search for tracks described with 'slow' and so on) - any ideas how do send data by clicking on a link? my html form is: Code: [Select] <body bgcolor="white"> <form action="test3.php" target="main" method="post"> <input type="text" name="searchkeywords" size=100><br> <input type="submit" value="Search"> <input name="searchkeywords" value="slow" type="submit"> </form> <DIV align="center" style="left : 240px; position : absolute; top : 100px;"><iframe src ="test3.php" width="1000" height="800" name="main" frameborder="2" scrolling="no"> <p>Your browser does not support iframes.</p> </iframe></DIV> </body> my php query file is: Code: [Select] <?php $con = mysql_connect("localhost","root","password"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("test", $con); $result = mysql_query("SELECT * FROM music WHERE keywords LIKE '%$_POST[searchkeywords]%'"); $txt1='<A HREF="/audioplayer-standalone/'; $txt2='" ><IMG src="images/misc_23.png" width="32" height="32" align="left" border="0"></A>'; $txt3='<script language="JavaScript" src="/audioplayer-standalone/audio-player.js"></script><object type="application/x-shockwave-flash" data="/audioplayer-standalone/player.swf" id="audioplayer'; $txt4='" height="24" width="290"><param name="movie" value="/audioplayer-standalone/player.swf"><param name="FlashVars" value="playerID=audioplayer'; $txt5='&soundFile=/audioplayer-standalone/'; $txt6='"><param name="quality" value="high"><param name="menu" value="false"><param name="wmode" value="transparent"> </object>'; echo "<table border='1'> <tr> <th width='220' align='left'>Track Name</th> <th width='220' align='left'>Artist</th> <th width='220' align='left'>Description</th> <th></th> <th></th> </tr>"; while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['track'] .

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.

Thanks For Your Help Guys! 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. df Hi i am an absolute PHP/MYSQL Novice but i guess we all gotta start somewhere. I have a table in my database with names and addresses, f_name, s_name, street, zip_code, city etc etc etc What i want to do is display a drop down of all cities in my database then click on any city in the list to display all the details of people in that city, showing all fields. So i have got this far .. Code: [Select] $conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql'); $dbname = 'cities_wrdp1'; mysql_select_db($dbname); $sql = "SELECT DISTINCT City FROM PBM"; $result = mysql_query($sql); echo "<select name='City'>"; while ($row = mysql_fetch_array($result)) { echo "<option value='" . $row['City'] . "'>" . $row['City'] . "</option>"; } echo "</select>"; This produces the nice drop down list of cities from the database ... Now on click i would like to return results similar to this Code: [Select] $conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql'); $dbname = 'cities_wrdp1'; mysql_select_db($dbname); $query = sprintf("SELECT * FROM PBM"); $result = mysql_query($query); if (!$result) { $message = 'Invalid query: ' . mysql_error() . "\n"; $message .= 'Whole query: ' . $query; die($message); } echo "<br />"; echo "<table border='0'>"; while ($row = mysql_fetch_assoc($result)) { echo "<tr><td>"; echo "<a href=\"" .$row['profileURL'] . "\"> <img src=\"" . $row['faviconURL'] . "\" border=0 alt=\"" . $row["Thumbnail"] . "\"> </a>"; echo "</td><td align='center'>"; echo $row['f_name']; echo "</td><td align='center'>"; echo $row['s_name']; echo "</td><td align='center'>"; echo $row['number']; echo "</td><td align='center'>"; echo $row['street']; echo "</td><td align='center'>"; echo $row['zip']; echo "</td><td align='center'>"; echo $row['city']; echo "</td><td align='center'>"; echo $row['Country']; echo "</td><td align='center'>"; echo $row['email_address']; echo "</td><td align='center'>"; echo $row['fb']; echo "</td><td align='center'>"; echo $row['web_site']; echo "</td><td align='center'>"; echo $row['phone']; echo "</td><td align='center'>"; echo $row['land']; echo "</td><td align='center'>"; echo $row['age']; echo "</td></tr>"; } echo "</table>"; mysql_free_result($result); So my question is .. how do i make the first piece of code selectable to produce similar results to the second piece of code based on the city selected ? Thanks for any help .. and please excuse my ignorance .. Hello all. First of all, if this isn't the right place for this topic, please excuse me and may the moderators/admins move it where it should belong. Second, I'm trying to make a mysql search - Everything works, but if say, a user searches for 34 it displays all numbers that have the number 34 in them. I want the results to be exact - if a user searches for 34, to display only 34, not 334, 5034 or 3401 (like it happens now). Here's the code: Code: [Select] <?php mysql_connect ("**************", "*******","*****") or die (mysql_error()); mysql_select_db ("********"); $term = $_POST['term']; $sql = mysql_query("select * FROM countries WHERE cocode LIKE '%$term%'"); while ($row = mysql_fetch_array($sql)){ echo '<br/> Code: '.$row['cocode']; echo '<br/> Country: '.$row['coname']; echo '<br/><br/>'; } ?> If you have any questions, you're welcome to ask them in the thread.

Natasha T 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 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 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 Hey guys, Could somebody help me with a little problem I am having, I havew spent the last two weeks trying different ways to search my database without success. What I want to do is have an input field that I can search only one column of my database.

$requestedtag = $con->real_escape_string($_GET['tag']); $sql = "SELECT * FROM images WHERE tags = '$requestedtag' ORDER BY ID DESC LIMIT 12"; $result = $con->query($sql); if ($result->num_rows > 0) { while($row = $result->fetch_assoc()) { $image_id = $row["ID"]; $image_title = $row["Title"]; $image_url = $row["ImgURL"]; $image_tags = $row["Tags"]; echo '<div class="col-3"><div class="thumb"><a href="/image.php?id='.$image_id.'" title="'.$image_title.'"><img src="'.$image_url.'"></img></a></div></div>'; } } But it doesnt return anything. I think the problem is that row["Tags"]; is divided by "," from tags and i should split it somehow but i dont really know what to do... I am using ajax live search to retrieve data from MySQL table. It works fine. However I noticed that it only returns a single result that matches the entire word instead of multiple results that match only the first couple letters. For e.g. DB Table ---------------- 1. Foot 2. Foot Path 3. Football ---------------- If I type "foo" in the ajax search field, it won't return any results. But if I type "foot", it'll return "Foot". It won't return the other two results that contain the letters "Foot". Here's my query $param_term = $_POST["term"] . '%'; $get_data = $db->prepare("SELECT name FROM table WHERE title LIKE :param"); $get_data->bindParam(':param', $param_term); $get_data->execute();
I was wondering how can I improve the above query so that it looks for all potential results based on partial matching of letters? |
