PHP - Sorting And Filtering This Script By Form
Hello Everybody!
From all the PHP forums, this seems to be the best one, since I find the words 'freaks' and 'addicted' everywhere, so I give it a shot for the first time Yesterday I've been struggling with a piece of code all day, which got me really frustrated. I'm a bit of a noob yet, but usually Iget quite far with a bit of googling. Not this time... I have a code and I want to be able to sort and filter the code with a form (It's for a portfolio). I know it has a lot to do with XXXX, but I can't get it working. Do I have to use a double array instead? (tried that also, but then I have to find a way to get the paging back...) Can someone help me out a bit maybe? I would be very very graceful! Here is the code I'm using: The index.php Code: [Select] <?php $page_comments = 2; //number of comments per page /* DEZE HIERONDER KAN MISSCHIEN WEG?? */ $page = 0; $page = (int)$_GET['p']; ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Sort/filter form</title> <style type="text/css"> <!-- div.gbsign{color:#F00;} .gbname{font-weight:bold;color:#FC0;} .gbdate{margin-left:30px;color:#F0C;} p.gbmessage{margin-top:-12px;color:#FCC;} p.extra_p{margin-top:-12px;color:#0F0;} p.extra2_p{margin-top:-12px;color:#00F;} --> </style> </head> <body> <form method=get style="display: inline;" name=''> <select name=orderby onChange=""> <option value='relevance'>Relevance</option> <option value='year'>Year</option> <option value='title_asc'>Title (A - Z)</option> <option value='title_desc'>Title (Z - A)</option><BR /> </select> <input type="checkbox">Film</input> <input type="checkbox">TV</input> <input type="checkbox">Fiction</input> <input type="checkbox">Documentary / Reality</input> <input type="checkbox">Commercial</input> <input type="checkbox">In Opdracht</input> </form> <?php $gbfile = 'gbcontentfile.php'; $fh = @fopen($gbfile, "r"); $fcontent = @fread($fh, filesize($gbfile)); if($fcontent){ $cnt = substr_count($fcontent,'<?php /* '); $cnt = $cnt/2; $maxp = 0; if($cnt>$page_comments)$maxp = (int)($cnt/$page_comments); preg_match_all("/\<\?php .*? \?\>(.*?)\<\?php .*? \?\>/is", $fcontent, $entries); $ini = $page*$page_comments; $end = ($page+1)*$page_comments; $ovo = array('<1>','<2>','<3>','<4>','<5>','<6>','<7>'); $sovim = array( "<div class=\"gbsign\"> <p><span class=\"gbname\">", "</span> <span class=\"gbdate\">", "</span> </p> <p class=\"gbmessage\">", "</p> <p class=\"extra_p\">", "</p> <p class=\"extra2_p\">", "</p> <p class=\"extra2_p\">", "</p> <p class=\"extra2_p\">", " </p> </div> " ); for($j=$ini;$j<$end;$j++)echo str_replace($ovo,$sovim,$entries[1][$j]); if($maxp>-1){ echo '<p>'.strstr($fcontent,'<!--').'

I found this already, but I can not get the two combined: Code: [Select] <?PHP $data = array( array("firstname" => "Mary", "lastname" => "Johnson", "age" => 25), array("firstname" => "Amanda", "lastname" => "Miller", "age" => 18), array("firstname" => "James", "lastname" => "Brown", "age" => 31), array("firstname" => "Patricia", "lastname" => "Williams", "age" => 7), array("firstname" => "Michael", "lastname" => "Davis", "age" => 43), array("firstname" => "Sarah", "lastname" => "Miller", "age" => 24), array("firstname" => "Patrick", "lastname" => "Miller", "age" => 27) ); ?> <?PHP function orderBy($data, $field) { $code = "return strnatcmp(\$a['$field'], \$b['$field']);"; usort($data, create_function('$a,$b', $code)); return $data; } $data = orderBy($data, 'age'); ?> Thanks in advance!! Sander Similar TutorialsI’m writing a small application that allows me/users to add their own inputs so they can store their own data. It’s kind of like, a user defined database. Think of a super simple “filemaker” kind of application. The way I’ve set this up is like this:
Table: item fields: item_id, user_id Table item_attribute Fields: item_attribute_id, item_id, name, valueAfter my query I end up with stuff like this: $data = array( 0=>array( '123'=>array( 'name'=>'Year', 'value'=>'1985' ), '7'=>array( 'name'=>'Title', 'value'=>'Title For 1985' ), '25'=>array( 'name'=>'Length', 'value'=>'60' ) ), 1=>array( '123'=>array( 'name'=>'Year', 'value'=>'1990' ), '7'=>array( 'name'=>'Title', 'value'=>'Title For 1990' ), '25'=>array( 'name'=>'Length', 'value'=>'44' ) ), 2=>array( '123'=>array( 'name'=>'Year', 'value'=>'1965' ), '7'=>array( 'name'=>'Title', 'value'=>'Title For 1965' ), '25'=>array( 'name'=>'Length', 'value'=>'122' ) ) );This seems to work great as there is no limit to what a user can add - it's working like I would like it to... But now that I’m trying to add sorting/filtering/pagination to results things have gotten extremely difficult on the back end. The only thing I can think of is to pull all the data and then use php algorithms to sort/filter/paginate before sending over to web page. I can see this getting slow if I eventually have to pull 1000s of records. Does anyone have advice in these matters? Should I rethink my db design? Can the results be used to create a temporary table and then sort on it? (don'n know how or if this is even possible) I need some help Thanks. Edited by fivestringsurf, 16 November 2014 - 12:28 PM. Hopefully the title fits this well enough. I am having trouble explaining my idea in words and therefore am having trouble researching what I would like to do. First off, let me say that I only have the most basic understanding of web development knowledge. I can usually look stuff up and hack stuff together and make it work. I am sure none of is done very efficiently, but as long as it works I am happy. This project started off as a simple idea. I have a list of events on my page. When clicking on an event, I want it to open up a page to the right with a signup form and a "table" displaying the sign-ups. Seemed easy enough. Originally I was going to use Google Docs to accomplish this all. An embedded calendar with the events at the left. When clicking on the event it opened up the desired event page in an <iframe> to the right. Inside of that there would have been an embedded Docs form which exports the data to a docs spreadsheet. To the right of the form, the docs Spreadsheet would have been embedded. In my head this works, and on paper it works. However, when trying to embed two Google elements, one would break. Even if I had one on the page, and one embedded on a page that was being displayed via <iframe>. You can see this here, www.leagues.simrigs.com , I stopped mid way through when I realized it wasn't going to work. Anyway, so now I want to lose the whole Google aspect completely. I will have off to the left, nicely styled image "button" links to each event page. I still want the pages to open in an <iframe> off to the right. This is simple enough I want to keep it all within the same page. This part is easy enough for me. The part I am having trouble with now is the form and spreadsheet part. I can manage making the signup form. After that I am lost. I need to have this input data logged somewhere, sorted into a sensible manor, and then displayed on the page next to where they signed up. Hopefully this makes some sort of sense. It works in my mind, I just don't know how to describe it. If need be, I can do a little photoshop mockup on what I am looking for. Thanks in advance. I have a form and script that is used to collect information from users. There is one field that is url. There is one field that is email. I want to filter out scripts. I also only want to allow url in the url field and email in the email field. Is there an easy way to filter? I have tried several pieces of code to no avail. Code: [Select] <?php $root = $_SERVER['DOCUMENT_ROOT']; include('/home/arts/public_html/shows/includes/config.db.php'); if ($link) { foreach ($_POST as $k => $v) { if (($k == "start_date") || ($k == "end_date") || ($k == "application_dead")) { $varray = explode("/",$v); $v = $varray[2] . "-" . $varray[0] . "-" . $varray[1]; } $v = "'" . addslashes($v) . "'"; if($k != "captcha_code") { $keys[] = $k; $vals[] = $v; } } $fields = implode(",", $keys); $values = implode(",", $vals); //$fields = "id," . $fields; //$values = "null," . $values; $sql = "INSERT into craft_shows ($fields) VALUES ($values)"; $result = mysql_query($sql,$link); if (!$result) { die('There was a problem with your submission. Refresh the page to try again'); } else { echo "Thank you for your submission.<br>"; echo "<a href=\"http://www.artsandcraftsnetwork.com/shows/\">Back to shows</a><br>"; echo "<a href=\"http://www.artsandcraftsnetwork.com/shows/shows_submit.php\">Submit another show</a>"; } } ?> Hi all, I was wondering if i can filter certain log files like using 2 keywords and get all the info inbetween? The log files are like <1 MB. The other problem i encounter is howto since i looked all over the net but cant seem to find usefull info about it. Can you help me out here? Hi guys I was wondering if anyone could point me in the right direction with this. I am using JSON to return the contents of a directory and then using a foreach loop to print each one to a new row in a table. Is there anyway to filter the results? Basically I just want to show the files that end in a .jar extension? Currently all sub directories and files are shown, however all the files I need to pull will be in the main directory. This is what I am using: Code: [Select] <?php foreach ($installedplugins1['success'] as $v) { echo "<tr><td>".$v."</td>"; echo "<td><a href='index.php?dp=".$v."'>Disable Plugin</a></td>"; } ?> Any hints or reading material? Cheers I'm pretty sure the problem is starring me in the face, but I can't seem to locate it. function filter($string) { //swear words pulled from bannedwordlist.com $f = fopen('../badwords.txt', 'r'); $bad_words = fread($f, filesize('../badwords.txt')); $bad_words = explode('\n', $bad_words); $input = strtolower($string); foreach($bad_words as $value) { $string = str_replace($value, '****', $input); } return $string; } UPDATED CODE function filter($string) { //swear words pulled from bannedwordlist.com $f = fopen('../badwords.txt', 'r'); $bad_words = fread($f, filesize('../badwords.txt')); $bad_words = explode('\n', $bad_words); $input = strtolower($string); $string = str_replace($bad_words, '****', $input); return $string; } I've already echoed out $value in the foreeach loop, and it does correctly retrieve the bad words and put them into an array. My only problem is, the returned string is still in strtolower() form, and the words aren't censored. :/ I have a SQL statement which is difficult to use PDO on, it might not even be possible to do.
So I'm filtering it like this:
$search = $_GET['search'];
$search = preg_replace("/[^A-Za-z0-9]/", " ", $search);
$search = $mysqli->real_escape_string($search);
Will this result in an acceptable level of security?
Edited by anderson_catchme, 16 September 2014 - 12:28 PM. I want to create a feature as you see nn this image, where it says 'filter your results' if a user clicks 'Detached Houses' then only detached houses will be displayed. if a user clicks 'Semi-detached' then only semi detached houses will be shown. Any help is really appreciated, thank you. Code: [Select] <table border="0" cellpadding="0" cellspacing="0"> <tr> <td><div id="filter"><p class="houses" style="font-family:helvetica;color:#0155a1;font-size:14px;background:url(cutouts/forsale/filter.jpg) no-repeat;"><b><u>Houses</u></b> <br /> <span class="dh"><b><u>Detached Houses</u></b></span><?php // Make a MySQL Connection mysql_connect("localhost", "admin", "1admin") or die(mysql_error()); mysql_select_db("test") or die(mysql_error()); // Get a specific result from the "example" table $result = mysql_query("SELECT * FROM example WHERE name='Sandy Smith'") or die(mysql_error()); // get the first (and hopefully only) entry from the result $row = mysql_fetch_array( $result ); // Print out the contents of each row into a table echo $row['name']." - ".$row['age']; ?> <br /> <span class="dh"><b><u>Semi-detached houses</u></b></span> <br /> <span class="dh"><b><u>Terraced houses</u></b></span> <br /> <br /> <b><u>Flats / Apartments</u></b> </p></div></td> First off, i have made a validation class using array_diff() to check if there are invalid characters submitted by a user. Some extracts: Code: [Select] $this->chr_alpha_lower=array('a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'); $this->chr_alpha_upper=array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'); $this->chr_numeric=array('0','1','2','3','4','5','6','7','8','9'); $this->chr_symbol=array(' ','!','@','#','$','%','&','(',')','[',']','.',',',':',';','\'','"','/','=','\\','-','_','?'); ... // lets say only alpha and numeric characters are allowed $allowed_characters=array(); $allowed_characters=array_merge($allowed_characters,$this->chr_alpha_lower,$this->chr_alpha_upper); $allowed_characters=array_merge($allowed_characters,$this->chr_numeric); $input_split=str_split($this->input); $invalid=array_diff($input_split,$allowed_characters); if(empty($invalid)){ return true; } return false; I have two questions. First, for acsii characters is this method 'full proof' or is there a way for someone to get around this validation script? Second, a new site im developing is going to be built with UTF-8 in mind so people can use the site in their own language. How do i validate UTF-8 user input? I know about mb_strings and sanitizing UTF-8 input using this: Code: [Select] preg_match_all('/([\x09\x0a\x0d\x20-\x7e]'. // ASCII characters '|[\xc2-\xdf][\x80-\xbf]'. // 2-byte (except overly longs) '|\xe0[\xa0-\xbf][\x80-\xbf]'. // 3 byte (except overly longs) '|[\xe1-\xec\xee\xef][\x80-\xbf]{2}'. // 3 byte (except overly longs) '|\xed[\x80-\x9f][\x80-\xbf])+/', // 3 byte (except UTF-16 surrogates) $input, $clean_pieces ); $clean_output = join('?', $clean_pieces[0] ); But how do i know what to filter? Example: a field for the user to input first name English: only alpha characters Other language: ????? Help much appreciated. hey guys i was generally wondering...is it good practice to add_slashes and use mysqli_real_escape_string when entering data into the database?
then to strip slashes when extracting rows?
is this the right way to go around things...thanks
This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=334433.0 Hi all, I am working on a tool to pull data remotely and the data is set to xml format. I want to post items that meet a certain criteria only, essentially there are several layers/tags on the data being brought over. The sStatus is the primary item I am looking for, not only that but only if it has or equals to "Waiting". Any thoughts or suggestions greatly appreciated. Below is the basic code I have in place currently and am working on. <code> <?php $soapclient = new SoapClient("https://secure.logmeinrescue.com/api/api.asmx?wsdl"); $sEmail = "dummy@dum.com"; $sPassword = "dum123"; $iNodeID = "123456"; $eNodeRef = "NODE"; $sAuthCode = ""; $loginparams = array ( 'sEmail' => $sEmail, 'sPassword' => $sPassword); $loginResult = $soapclient->login($loginparams); $output = array( 'eOutput' => "XML" ); $outputResponse = $soapclient->setOutput($output); $sessionparams = array( 'iNodeID' => $iNodeID, 'eNodeRef' => $eNodeRef, 'sAuthCode' => $sAuthCode ); //get session(s) $sessionresult = $soapclient->getSession($sessionparams); $session = $sessionresult->aSessions; $sessionnodes = $session->SESSION; $session_status = $sessionnodes[$isessionNodes]->sStatus; print_r($sessionresult); ?> </code> Hi there I have the following array . Code: [Select] $products = array( array( Code => "CF1", Items => "Sand Tray", Cat => 'Tray', ), array( Code => "CF2", Items => "Mobile Computer Table", Cat => 'Table', ), array( Code => "CF3", Items => "General Service Trolley", Cat => 'Trolley', ), array( Code => "CF4", Items => "TV Trolley", Cat => 'Trolley', ), array( Code => "CF5", Items => "Overhead Projector Trolley", Cat => 'Trolley', ), array( Code => "CF6", Items => "Book Trolley", Cat => 'Tolley', ), array( Code => "CF7", Items => "Stacking Chairs", Cat => 'Chairs', ), ); What I want to do is select each by 'Cat'. For example I simply want to display all the trolleys. I was wondering how I do this? What functions would I use in PHP? Thanks a million Hi, I have an issue, I cant filter my data from DB.

hi, i am trying to filter my gps history points. i would like to ignore points if they are too close to the previous position. i can do this like so. $old_lat = $old_long = "0"; foreach($history['data'] as $record) { //calculate distance in meters $distance = distance($record['latitude'], $record['longitude'], $old_lat, $old_long, "V"); if($distance >= 300) { echo 'add(jQuery(this), number += 1, "' . date("d-m-Y @ h:i:s",$record['timestamp']) .

'");'; $old_lat = $record['latitude']; $old_long = $record['longitude']; } the problem with the above is that if i arrive home at 6pm on friday and stay outside my house for 24hours, it will show the latest position as at 6pm on fri. i would like it to show the 6pm friday position but with a date 'from and to' time like (28/10/11 18:00 - 29/10/11 18:00) rarther than just (28/10/11 18:00) which looks inacurate. Possible? Hey guys, we have a website where people are able to post things, and we don't want to allow anyone to be able to post their street address, for obvious reasons. I'm really stuck on this one, I've looked for some regular expressions to no avail...one idea we did have was to check a text for an address then check to see if it was a valid address with the google maps API but then again...it goes back to having a regular expression for capturing the street address. I was wanting to know, is there any way I will be able to catch whether a user has posted an address? I was going to post this in the regex section but I'm not sure if I should use any regex's or if there might be another way. Put basically I need to be able to strip a street address from the text if a user posts one. I'm pretty sure it's probably not possible, but I figured I'd ask first. Thanks for any help anyone can provide! Hi all I am building a page to filter SQL values but I'm not sure how to write the code for the query. My URL looks like this: stone.php?category=Wood&type=4&colour=1&Submit=Submit Firstly, can I remove the submit from the URL? Then I have my code to create the query: $fetchData=mysql_query("SELECT * FROM `products` WHERE category = "'.$_GET'category.'""); Can I combine this for the type and colour? Many thanks Pete Im struggling with how to filter items that have multiple categorises say if i wanted to search for a shoe that is good for walking and hiking in my database?
