  1. Dont validate by mime instead validate by extracting the extension from $_FILES['file']['name']
  2. $file['downloads'] / 1000; if($file['file_size'] >= 5242880 && $file['downloads'] >= 1000){ $earnings = $file['downloads'] / 1000; mysql_query("UPDATE uploads SET earnings = earnings+".$earnings." WHERE file_id = '".$file['file_id']."'"); }
  3. @CV Im validating them before they are called to the function using (intval() or the int typecast along with a mysql_num_rows() to check it exists), and its only me who has the permissions to access the functions etc. - so its all prety safe. and @Daniel Cheers for the workaround.
  4. The function selects a rank following a query which is dependant on the user_id parem, so im not sure how that'd work?
  5. I've read in several tutorials, that globals within functions are considered 'dirty' im using them within my code, and was wondering if it could be improved in a more effective way? My code: <?php function rank($user_id){ global $rank, $level; $ptssql = mysql_query("SELECT * FROM site_users WHERE user_id = '$user_id'"); $ptsrow = mysql_fetch_array($ptssql); $points = $ptsrow['points']; if ($points <= 99){ $rank = "Jr Member"; $level = 0; } elseif ($points >= 100 && $points <= 299){ $rank = "Member"; $level = 1; } } //usage rank(47); ?> Your Rank: <?php echo $rank; ?> All help appreciated
  6. I was wondering how would i prevent excess login attempts for e.g. like if failed login attempts are = to X amount of times then echo an error and make the person wait X minutes. Im not looking for something advanced, something basic would do (atleast in this moment in time), was thinking perhaps sessions or cookies? I already have the following code, which seems to work but only allows the login form to be submitted once, trying to modify it to fit my needs, any help is appreciated. <?php function prevent_multi_submit($type = "post", $excl = "validator") { $string = ""; foreach ($_POST as $key => $val) { // this test is to exclude a single variable, f.e. a captcha value if ($key != $excl) { $string .= $val; } } if (isset($_SESSION['last'])) { if ($_SESSION['last'] === md5($string)) { return false; } else { $_SESSION['last'] = md5($string); return true; } } else { $_SESSION['last'] = md5($string); return true; } } if (isset($_POST)) { if ($_POST['field'] != "" && strlen < 25) { // place here the form validation and other controls if (prevent_multi_submit()) { // use the function before you call the database mysql_query("INSERT INTO tabel..."); // or send a mail like... mail($mailto, $sub, $body); } else { echo "The form is already processed"; } } else { // your error about invalid fields } } ?>
  7. Using ChemicalBliss's code you can do the following: <?php function callback($url){ $url = $url[1]; if (substr($url,-5) == (".jpeg") || substr($url,-4) == ".jpg" || substr($url,-4) == ".gif" || substr($url,-4) == ".png"){ return '<img src="'.$url.'" />'; } else return $url; } $content = "blah blah blah http://sometest.web.com/folder%4d/test-image.png"; $content = preg_replace_callback("/(http:\/\/([^\/]+)[^\s]*)/", "callback", $content); echo $content; ?>
  8. Via cURL (logging into an official play station login page then extracting neccessary info using regular expressions) or using their API (if they have one).
  9. Is their a more effective way of doing this?, as something is telling me it may cause load issues in the future (as the db gets larger?). What im trying to do is extract all the unique user_level's from the db so they return an array. (im current querying the entire db and then extracting all the user_level's and doing the unique php side, as im sure on how to do that all in 1 query?) My code: <?php $user_group_levels = array(); $user_group_result = mysql_query("SELECT * FROM site_users"); while($user_group_data = mysql_fetch_array($user_group_result)){ $user_group_levels[] = $user_group_data['user_level']; } $user_group_levels = array_unique($user_group_levels); foreach($user_group_levels as $user_group){ ?> [<span class="<?php echo $user_group; ?>"><?php echo ucfirst($user_group); ?></span>] <?php } ?>
  10. Thanks that worked, xD, *feels dumb*
  11. Heres some code to explain what i mean: <?php $i = 11; if($i <= 10){ $i = 1; } elseif($i >= 10 && $i <= 20){ $i = 2; } elseif($i >= 20 && $i <= 30){ $i = 3; } //etc. //would output 2 echo $i; ?>
  12. I have the following code, which arranges an array of numbers in numerical order, and outputs another array. How do i turn for every 10 $i's $i = 1, so say if $i = 20, $i would be 2, if $i was 6 $i would be 1, if $i was 30, $i would be 3, if $i was 1 it would remain 1.... <?php $ids = array('90', '96'); //sort them in numerical order... sort($ids, SORT_NUMERIC); $i = 0; $x = 0; $New = array(); foreach($ids as $v) { $i++; $x++; if($i < 10){ $i = 1; } $New[$v] = "&pg=$i#$x"; } ?> Sorry for bad description, sort of lost myself on how to describe it lol
  13. Yes but make sure to add delimiters around the expression. (look it up via google for more info)
  14. To avoid sql errors, escape the data, with mysql_real_escape_string() before querying.
  15. thanks, but is that the best free commenting system? Looking at their websites, they are the self proclaimed best.
  16. Heres what I've come up with, but the line numbers are not correct (they are not the correct ones for the opening tags): <?php function close_tags($text) { $patt_open = "%((?<!</)(?<=<)[\s]*[^/!>\s]+(?=>|[\s]+[^>]*[^/]>)(?!/>))%"; $patt_close = "%((?<=</)([^>]+)(?=>))%"; if (preg_match_all($patt_open, $text, $matches)) { $m_open = $matches[1]; $m_lines = array(); $i = 0; $data = str_replace(array("\r\n", "\r"), "\n", $text); $data = explode("\n", $text); foreach ($m_open as $m_tag) for ($line = 0; $line < count($data); $line++) { if (strpos($data[$line], $m_tag) !== false) { $i++; $m_lines[$i] = $line; } } if (!empty($m_open)) { preg_match_all($patt_close, $text, $matches2); $m_close = $matches2[1]; if (count($m_open) > count($m_close)) { $m_lines = array_slice($m_lines, 0, count($m_open)); $m_lines = array_reverse($m_lines); $m_open = array_reverse($m_open); foreach ($m_close as $tag) $c_tags[$tag]++; $c = array_combine($m_lines, $m_open); foreach ($c as $line => $ctag) { if ($c_tags[$tag]-- <= 0) { $text .= "\n</{$ctag}>(Line {$line})"; } } } } } $text = preg_replace('~</(img|\?php|input|br)>\(Line ([0-9]+)\)~', '', $text); return $text; } ?> Any help?
  17. I was thinking of integrating file() to retrieve the line nums?, so the final array would consist of the match along with the line number. //matches //lines nums $matches = array( "some match" => 45 );
  18. Hi, I want to use preg_match_all(), but want to add the line numbers to the array for each of the matches, how would this be achieved?
  19. Its some sort of validator and I'd need the line nums for debugging (I got some code which consists of php code and html - not my code im just helping to debug, but the html does'nt pass w3 validation, looking at it; some of the tags are not closed, but I can't manually flick through the code to see which arn't closed as the html is nested and would confuse me). So that function works perfect, but I'd require the line nums so i can then manually check where the tags are opened and hopefully correct them by placing the closed tag in the correct place. I've looked at file() function, which gives line nums, but not sure how to integrate it.
  20. Anyone can help, please? :-\
  21. Hi, I'm got a function from a user note on php.net, which adds the closing html tags to the end of a html string if that tags has'nt been closed, however I'd like for it to display the line number of the original tag (which has'nt been closed), next to the closed tag. Heres the function: <?php function close_tags($text) { $patt_open = "%((?<!</)(?<=<)[\s]*[^/!>\s]+(?=>|[\s]+[^>]*[^/]>)(?!/>))%"; $patt_close = "%((?<=</)([^>]+)(?=>))%"; if (preg_match_all($patt_open,$text,$matches)) { $m_open = $matches[1]; if(!empty($m_open)) { preg_match_all($patt_close,$text,$matches2); $m_close = $matches2[1]; if (count($m_open) > count($m_close)) { $m_open = array_reverse($m_open); foreach ($m_close as $tag) $c_tags[$tag]++; foreach ($m_open as $k => $tag) if ($c_tags[$tag]--<=0) if($tag != "?php" && $tag != "br" && $tag != "img"){ $text.='</'.$tag.'>'; } } } } return $text; } $html = '<body> hey....<tr>'; highlight_string(close_tags($html)); ?> Which would output: <body> hey....<tr></tr></body> However I'd like it to output (the line number of the opening tag next to the closing tag): <body> hey....<tr></tr>(line 2)</body>(line 1) All help greatly appreciated.
  22. Lookinto remote file inclusion, your code is vulnerabile
  23. Sorry, to bump, but this thread was way off into the pagination, was the only way to make the thread visible. Anyone could help?
