PHP - Does Anyone Have Experience With Filter()
HI all,
Yesterday i read quite alot about htmlentities() htmlspecialchars() mysql_real_escape_string But today i stumbled upon filter() (http://www.w3schools.com/php/php_filter.asp). Does anyone know if this is also a good way to sanitize and may even be an alternative for the other functions? OR is it something completly different? I am still a novice with this so please enlighten me : ) TY Similar Tutorials//level 2 - 500 //level 3 - 1500 //level 4 - 3500 //level 5 - 6000 function experience($L) { return $L * 495; } function Get_The_Level($exp) { return floor($exp / 495) + 60; } function Get_Max_Exp($L){ $end=0; if ($exp == 0){ return 0; $end =1; } for($L=1;($L<1000 && $end==0);$L++) { $exp = experience($L); //echo $exp; if ($exp >= $user_class->exp){ return $exp; $end=1; } } } cant get over level 70 can any one help to get it like level 1=200 level 2 =400 level 3= 600 and so on any help I am in the process of developing a commercial web application to be offered as a SAAS to small businesses in the U.S. on a subscription basis. I have been working with a developer for a while now and the project timelines are starting to slip. I need someone to help get the project back on track and completed so we can roll it out and I can start selling it. Once the project is completed, there will be many ongoing opportunities for future work making customizations for specific customers and developing enhancements and new features and versions. It could very easily turn into a full time gig.
A large portion of the project is done but there are some key features that need to be completed.
I need to get this done as soon as possible - please contact me on skype - patrick.mathews67 or by email - patrick@systemvillage.com.
It was started using phpixie and I think it would be best to continue with it, however, I need to get it done so I am open to suggestions.
I have started learning OOP, by following a few tutorials, My problem with most tutorial is they show you how, but don't tell you the what and the why. It's all good an well seeing what to do, but if you have no idea why it's being done, you don't learn much. I started a tutorial on Udemy but am not actually gaining a lot from it. I want to alter the code so that it will do it the way I want it to. I am not wanting you to write the code for me, if you do please explain it so that I can understand the logic, preferably show me where to make changes and point me at the php tutorial that can solve my problem. I have been trying to solve this for a couple of weeks now, I tried a few things but none worked.
The full followLinks function
function followLinks($url) {
global $alreadyCrawled;
global $crawling;
$host = parse_url($url)["host"];
$parser = new DomDocumentParser($url);
$linkList = $parser->getLinks();
foreach($linkList as $link) {
$href = $link->getAttribute("href");
if((substr($href, 0, 3) !== "../") AND (strpos($href, $host) === false)) {
continue;
}
else if(strpos($href, "#") !== false) {
continue;
}
else if(substr($href, 0, 11) == "javascript:") {
continue;
}
// I need to change this below somehow, the two arrays are identical,
// What I want to do is move $href(crawled) to $alreadyCrawled and remove it from $crawling
// I also want to check if the current $href (crawling) is in $alreadyCrawled and if it is skip crawling and move on to the next one.
//In essence I want to prevent the crawler from crawling anything already crawled in order to speed up the crawler.
$href = createLink($href, $url);
if(!in_array($href, $alreadyCrawled)) {
$alreadyCrawled[] = $href;
$crawling[] = $href;
} else { continue;}
echo $href . "<br>";
}
array_shift($crawling);
foreach($crawling as $site) {
followLinks($site);
}
}
$startUrl = "https://imagimedia.co.za";
followLinks($startUrl);

But that is not my main issue. Hi ! I have an 2d array like this: column 1 column 2 column 3 $data[0][0] $data[0][1] $data[0][2] $data[0][0] RDR -1.3 0.001 $data[1][0] RQR 0.4 0.01 $data[2][0] DDR 1 0.00004 and more... Now i need to filter this data. I only need the rows with column 3 < 0.01 AND column2 > 1 or column 2 < -1 . I have this, but it doesn't work: $teller = 0; for($i = 0; $aantal>$i; $i++) { if($data[$i][2]<=0.01) { $p[$teller][0] = $data[$i][0]; $p[$teller][1] = $data[$i][1]; $p[$teller][2] = $data[$i][2]; $teller++; } } $teller2 = 0; for($i = 0; $teller>$i; $i++) { if($p[$i][1] < -1 || $p[$i][1] > 1 ) { #als de p value kleiner is dan 0.01 dan alles kopieren in een nieuwe array $r[$teller2][0] = $p[$i][0]; $r[$teller2][1] = $p[$i][1]; $r[$teller2][2] = $p[$i][2]; $teller2++; } } Can you help me? Hi,
I'm trying to make a program that filters data out of a website. Now I've got a problem.
For example, I've this line:
<td class="maintxt" width="200"><a href="profile.php?x=Stranger">Stranger</a></td><td class="maintxt" width="200">Godfather (96.76%)</td><td class="maintxt" width="200"><i><a href="clanprofile.php?x=Ettertjes">Ettertjes</a></i></td>Form this line I want to set the word "Stranger" in a variable, and do the same for the word "Godfather". What is the best method to do this? Thanks in advance, iRoot121 I have a MySql table full of records. id owner car location on my page i have these results in a table i want to set a filter up so the table will only show cars from eg location England. at the minute its just set to show cars that owner has but i want a location filter any help so I'm running a query on a database to get address's $address = $row['address']; it returns "1234 Test St" I want to be able to sort all the records by the street name without the numbers Hey guys i am using a global filter on my $_POST function filter($str){return htmlentities($str, ENT_QUOTES);} $_POST = array_map('filter', $_POST); It helps me encode the stuff into the database. It works great on all my fields exept my arrays ... Ex: fields like this <input type="text" name="name[]" size="20"> breaks Any sugestions on gething this global filter working? I have some text boxes for searching the students in database also i have a drop down box for selecting student with balance amount to be paid tell me how to filter or search the list of stuents Code: [Select] <select> <option value="">All </option> <option value="">Unpaid </option> <option value="">Paid </option> </select> Hi. I was hoping someone could tell me whether this is possible and if so how I could go about doing it preferably with a tutorial as im pretty new to programming. I have a database that will contain 100's of records. I want users to be able to select filter parameters on this data by both text and checkboxes with it automatically updating the results (hopefully without page reload). I managed this so far using this Jquery filter script: http://www.picnet.com.au/picnet-table-filter.html. As this will table will have so many rows however I think it would take ages to load so instead I would like to paginate the table but still allow filters applied to affect all records not just the ones displayed on the current page. Any ideas on how i could do this? Thanks in advance for your help. Code: [Select] SELECT * FROM table1,table2,table3,table4,table5 WHERE table1_f = table2_id AND table1_g = table3_id AND table4_p = table1_id AND table5 _m = table4_id ORDER BY RAND() LIMIT 1 Right, Now What I want to do, is have a filter form, which posts to the above, and if: $filter1 = ""; it wont be include in the above code $filter1 = "word"; then i want to include AND table3_n = '$filter1'; in the above code thanks in advance. Hey, I have a word filter which is dectecting strings that are only embedded in words. Which i don't want it to do. For example: If i want to filter "FR" and some one puts france - it flags it because france contains FR. How do i make it only look for "FR" on its own seperated from a word instead of it flagging nearly all words with the two letters together? Heres my filter: $text = 'testing'; //this should not return 1 // fill this array with the bad words you want to filter and their replacements $bads = array ("test"); foreach($bads as $key => $search_needle) { if(stristr($text, $search_needle) == TRUE) { return(1); break; } } Hello, I have a client with a "contact us" form who has recently been receiving a lot of spam emails from the form. I already have a session set in place so the form is only active one time. I am now creating a filter for the message to look for things like a url or bb style codes etc. What I've got seems to be working but would like your thoughts on maybe a better way of doing it or if you see something I may be missing. IF an offending text is detected the ip address is sent to me and I can block ip from the site. If the message passes it is sent to the client. This is the related code. Code: [Select] <?php $themessage=str_replace("\r",'<br>',$_POST['message']); $badwords=array("[", "url", "http", "link", ".com", ".net", ".org", ".biz", "<"); $o=0; foreach($badwords as $key2 => $value2){ $pos = strpos($themessage, $value2); if ($pos==0) { } else{ $o=$o+1; } } if ($o==0) { //compose and send email to client } else{ $useraddress=$_SERVER['REMOTE_ADDR']; //compose and send email to me containing offending address } ?> Hi there, I have one question about the function rand(), What if i want to have an number between 0 and 360 Without 90 to 180 so 91,92,93,94.....180 can't be the number how can i do that? btw, I know its possible through if,while,for and so on. But is there an other way to do this? hi all i just read an article at http://www.phpro.org/tutorials/PHP-Security.html about not trusting server variables like $_SERVER['PHP_SELF'] so they explain, it can't be trusted and so on, but when it comes to a real life example i have difficulty understandig what someone could do with it since i assume it only has effect at client side. they use a form and say that Code: [Select] <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> ... </form> They give as example that someone could do the following: add Code: [Select] <script>alert("XSS HERE");</script> But i don't see how that would have effect to anyone except for the one that inserts that. Could someone maybe explain this a little to me. Hi,
I want to use an external rss in my site but the problem is that i only want to grab feeds that contain certain keywords in the title,
This is what i got so far to display the feed:
<?php
$html = "";
$url = "http://www.feedsite.com/conv-rss.asp";
$xml = simplexml_load_file($url);
for($i = 0; $i < 5; $i++){
$title = $xml->channel->item[$i]->title;
$link = $xml->channel->item[$i]->link;
$description = $xml->channel->item[$i]->description;
$pubDate = $xml->channel->item[$i]->pubDate;
$html .= "<a href='$link'><h3>$title</h3></a>";
$html .= "$description";
$html .= "<br />$pubDate<hr />";
}
echo $html;
?>
The feed is a classified jobs but i only need the jobs listed for musicians, keywords could be: bassist, singer, drummer, musician, etc..
Thanks
Hi All I have a script which imports values from a csv file created using excel. However there are several blank values within the file where the person creating it has used blank columns to create whitespace in the file. I have used array_filter to remove these from the array, however how do I remove the redundant keys and 'squash' everything together so it is nice and neat? eg import would be , ,id, , surname, ,firstname, ,DOB, , address, , which returns array after array_filter [1]-> id [3]->surname [5]->firstname [7]->DOB [9]->address I want to return as an array which would be Quote [0]-> id [1]->surname [2]->firstname [3]->DOB [4]->address Is there a function to do this or would I need to create a custom one? I'm having some problems with a piece of software I use on a clients website. There is a "related items" function module available, with this module you can filter to show items from the same category OR in the same city. But now my client want's the module to show only items that are located in the same category AND the same city.
My PHP knowledge is just not good enough to solve this myself, that's why I ask for advice here. I already defined the lines of code that manage the filter, but I don't know how to make this from an "OR" filter to an "AND" filter. Can someone help me with this?
// Join over prop mid table if getting related by category
if($search_cat)
{
$cats = ipropertyHTML::getAvailableCats($property->id);
if($cats)
{
$searchwhere[] = 'pm.cat_id IN ('.implode(',', $cats).')';
}
}
// Filter by city.
if($property->city && $search_city) $searchwhere[] = 'p.city = '.$db->Quote($property->city);
if( count($searchwhere)) $query->where('('.implode(' OR ', $searchwhere).')');
I have attached the complete file in case that gives a better insight in the filter function.
Best regards, Niels

1 downloadsHello Guys, I need some help here.. I want to implement a Bad word filter and not quite sure how to do it.. I am grabbing the following vars from the text fields $ad_title = filter_var($_POST['ad_title'], FILTER_SANITIZE_STRING,FILTER_FLAG_NO_ENCODE_QUOTES); $ad_body = filter_var($_POST['description'], FILTER_SANITIZE_STRING,FILTER_FLAG_NO_ENCODE_QUOTES); Then its inserted into the db. I would like to run it through this function first.. Code: [Select] FUNCTION BadWordFilter(&$text, $replace){ // fill this array with the bad words you want to filter and their replacements $bads = ARRAY ( ARRAY("butt","b***"), ARRAY("poop","p***"), ARRAY("crap","c***") ); IF($replace==1) { //we are replacing $remember = $text; FOR($i=0;$i<sizeof($bads);$i++) { //go through each bad word $text = EREGI_REPLACE($bads[$i][0],$bads[$i][1],$text); //replace it } IF($remember!=$text) RETURN 1; //if there are any changes, return 1 } ELSE { //we are just checking FOR($i=0;$i<sizeof($bads);$i++) { //go through each bad word IF(EREGI($bads[$i][0],$text)) RETURN 1; //if we find any, return 1 } } } // this will replace all bad words with their replacements. $any is 1 if it found any $any = BadWordFilter($wordsToFilter,1); I really would also like to query a table for any words that match and then use a replacement like [censored] Any help would be greatly appreciated! How do I know if Filter extension is on with my webhost? Or does it always work with PHP5? If I cannot use it, can someone recommend a good regex to validate EMAIL addresses?? Thanks, Debbie |
