  1. Hello guys! I have literally started learning how to code. And I have come to the point when I got to deal with elseif syntax which is not working properly and messes up everything I have done so far. Here's the script $password = "tulip"; if ($password == "tulip") { echo '<b>Hello!</b><br> Welcome to the website Blaise!'; } else { echo '<b> The password or login is incorrect <br> Please try again </b>'; } elseif ( $password == "daisy") { echo '<b> Welcome Kate! </b>; } When I type in "daisy" nothing goes on and everything just gets stuck. Any help or explanation? Thanks

  6. I am having a heck of a time trying to process a large cURL request. I keep running into issues with the mysql server timing out and also using the callback function within the cURL script (see below). What I am attempting to do is to utilize cURL to log a user into a system (*due to legality issues I cannot specify which) and pull all of their work for the day. I have been successful at pulling all of the work, but each order contains multiple sub-items, each with a specific url. For instance, 300 work orders would translate to approximately 2000 sub-items. Pulling the 300 work order takes approximately 1.6 minutes. For some reason just pulling 10 sub-items is taking in upwards of 3 minutes. After hundreds (and I am not exaggerating) of attempts I have finally decided to reach out to see if someone can take a look at my script and offer some knowledge. Here is the process from a logic standpoint: Pull all user login data from database and log them into the system through cURL (*Works fine) Request all activity and customer information and Insert into database (*Works fine) Get all sub-items and insert them into the database (*ISSUES) Here is the process from a script standpoint: User clicks "Import" button which sends AJAX request to run importWork PHP function. This function only handles requesting the activity and customer information through cURL. (Due to the amount of time it takes for the sub-items to process I have broken up the process). importWork function returns via jSON the number of work orders processed. ***In testing I have also had the importWork function store the urls for all of the sub-items to my database. The only issue is that the logins will start to timeout (Not on my server but the server I am pulling the data from) before all the sub-items can process. javascript automatically sends another AJAX request to pull all of the sub-items. I am using a cURL Multi function to process the url requests. The function will return an array containing the html for each of the urls. I then parse the html to search for the underlying hrefs I need to access the workorders, customer information, and sub-items. So overall, my question is, what is the best way to handle a large cURL request of 2000 urls? Below you will see the rolling_curl function which I am attempting to use to handle the line items. For some reason it doesnt work at all. What I would like to do is simply send an array of urls to the rolling_curl function and have it request all the html for each url. Once a url is finished processing it should run the callback script to insert the data into the database. I figured it would be the best way to handle such a large request in a timely manner. ROLLING CURL FUNCTION: explanation: A function will put all sub-item urls and the corresponding activity ids into an associative array and pass it to the rolling_curl function. The callback function will parse the html and insert the needed data into the database. The only thing this function is doing at this time is dumping "Failed". I have ran the script using the same urls through the standard cURL multi function (See Below) and verified it is pulling the html (So it isn't an issue with the urls). public function rolling_curl($urldata, $callback = null, $custom_options = null) { set_time_limit(0); //extract data from $urldata $urls = $urldata['urls']; $activities = $urldata['activities']; // make sure the rolling window isn't greater than the # of urls $rolling_window = 95; $rolling_window = (sizeof($urls) < $rolling_window) ? sizeof($urls) : $rolling_window; $master = curl_multi_init(); $curl_arr = array(); // add additional curl options here $std_options = array(CURLOPT_RETURNTRANSFER => true, CURLOPT_FOLLOWLOCATION => true, CURLOPT_MAXREDIRS => 5); $options = ($custom_options) ? ($std_options + $custom_options) : $std_options; // start the first batch of requests for ($i = 0; $i < $rolling_window; $i++) { $ch = curl_init(); $options[CURLOPT_URL] = $urls[$i]; curl_setopt_array($ch,$options); curl_multi_add_handle($master, $ch); } do { while(($execrun = curl_multi_exec($master, $running)) == CURLM_CALL_MULTI_PERFORM); if($execrun != CURLM_OK) break; // a request was just completed -- find out which one while($done = curl_multi_info_read($master)) { $info = curl_getinfo($done['handle']); if ($info['http_code'] == 200) { $output = curl_multi_getcontent($done['handle']); // request successful. process output using the callback function. $ref = array_search($info['url'],$urls); $callback($output, $activities[$ref],1); // start a new request (it's important to do this before removing the old one) $ch = curl_init(); $options[CURLOPT_URL] = $urls[$i++]; // increment i curl_setopt_array($ch,$options); curl_multi_add_handle($master, $ch); // remove the curl handle that just completed curl_multi_remove_handle($master, $done['handle']); } else { // request failed. add error handling. $dmp = 'Failed!'; var_dump($dmp); } } } while ($running); curl_multi_close($master); return true; } } STANDARD cURL MULTI FUNCTION: public function requestData($urls) { set_time_limit(0); // Create get requests for each URL $mh = curl_multi_init(); foreach($urls as $i => $url) { $ch[$i] = curl_init($url); curl_setopt($ch[$i], CURLOPT_RETURNTRANSFER, 1); curl_multi_add_handle($mh, $ch[$i]); } // Start performing the request do { $execReturnValue = curl_multi_exec($mh, $runningHandles); } while ($execReturnValue == CURLM_CALL_MULTI_PERFORM); // Loop and continue processing the request while ($runningHandles && $execReturnValue == CURLM_OK) { // Wait forever for network $numberReady = curl_multi_select($mh); if ($numberReady != -1) { // Pull in any new data, or at least handle timeouts do { $execReturnValue = curl_multi_exec($mh, $runningHandles); } while ($execReturnValue == CURLM_CALL_MULTI_PERFORM); } } // Check for any errors if ($execReturnValue != CURLM_OK) { trigger_error("Curl multi read error $execReturnValue\n", E_USER_WARNING); } // Extract the content foreach($urls as $i => $url) { // Check for errors $curlError = curl_error($ch[$i]); if($curlError == "") { $res[$i] = curl_multi_getcontent($ch[$i]); } else { return "Curl error on handle $i: $curlError\n"; } // Remove and close the handle curl_multi_remove_handle($mh, $ch[$i]); curl_close($ch[$i]); } // Clean up the curl_multi handle curl_multi_close($mh); // Print the response data return $res; } An assistance would be greatly appreciated!!! I am racking my head against my desk at this point =0). I am open to any suggestions. I will completely scrap the code and take an alternate approach if you would be so kind as to direct me accordingly. FYI - I am running on a hosted, shared server which I have little control over. PHP plugins might not be a route I can take at this point. But if there is something you know of that will assist me, shoot it at me and I will talk with my hosting provider. THANK YOU!!!!

  10. This problem is driving me crazy! I have been browsing my site using IE 10, just to see how it looks. Every time I click from one page to another, the body background image appears and disappears very quickly, as if it has to re-download for every page. Browsing the Web, I discovered that this is a common problem. Apparently, IE doesn't cache background images properly or something. I found a variety of "fixes". I tried them all and none of them have worked, including these three: <img src="images/dark-texture.jpg" style="display:none" /> <META http-equiv="Page-Enter" content="blendTrans(Duration=0.1)"> <META http-equiv="Page-Exit" content="blendTrans(Duration=0.1)"> <!--[if IE]> <meta http-equiv="Page-Enter" content="blendTrans(duration=0)" /> <meta http-equiv="Page-Exit" content="blendTrans(duration=0)" /> <![endif]--> Do you guys know how to fix this problem? My body CSS styling looks like this: body { font-family: Verdana, Helvetica, FreeSans, Sans-serif; font-size: 100%; padding: 0; margin: 0; background-image: url(images/dark-texture.jpg); } My website is Self Help Videos.
  11. Hello. I have a problem with my website. When I introduce the symbols " or ' through text editor (PHP based), the database adds a / to the code. The problem happens in text, but also in pictures or embeded iframes, etc.. Example: Correct snipet of code to go to DB: Felipe Nasr: "seria ótimo chegar à F1 com o António Félix da Costa" How it goes to DB: Felipe Nasr: "/seria ótimo chegar à F1 com o António Félix da Costa/" I have localhost, and two different hosts to my website (.cwahi.net and .atspace.eu). The files are the same in the three cases, but this problem only happens in atspace.eu... Can it be a server problem? Thank you in advance!
  12. Hello! I need to create a dynamic page title and description to my website. However, the content is all generated from "index.php" page (example: the URL of post is [...].net/?id=2 ). So, title and description are the same in all pages, the website only has a "real" php file. So, how can I change the title with this situation? I have a mysql table for news and another for news/posts. Content generator PHP lines: <!-- Header --> <?php if (isset($_REQUEST["id"])) { $query = "SELECT * FROM news WHERE news_id=".$_REQUEST["id"].""; $result = mysql_query($query); $row = mysql_fetch_array($result); ?> <div class="twelve columns"> <div class="row"><h3 class="n3"><?php echo $row["news_title"]; ?></h3> </div> </div> <div class="row"><!-- Row interior--> <div class="twelve columns"> <div class="panel"> <p id="data"><?php echo $row["news_date"]; ?>, <?php echo$row["hour"] ;?> GMT</p> <p><?php echo $row["news_post"]; ?></p>

  16. Hi, I've got some issues with my salting when I register... basically everything works fine apart from the salting and I can't get my head around it? Here's my php register function: public function register() { $correct = false; try { $con = new PDO( DB_DSN, DB_USERNAME, DB_PASSWORD ); $con->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION ); $sql = "INSERT INTO list_members(username, email, password) VALUES(:username, :email, :password)"; $stmt = $con->prepare( $sql ); $stmt->bindValue( "username", $this->username, PDO::PARAM_STR ); $stmt->bindValue( "email", $this->email, PDO::PARAM_STR ); $stmt->bindValue( "password", hash("sha256", $this->password . $this->salt), PDO::PARAM_STR ); $stmt->execute(); return header('Location: index.html'); }catch( PDOException $e ) { return $e->getMessage(); } } And then I have my public variables displayed like this: public $username = null; public $email = null; public $password = null; public $salt = "Zo4rU5Z1YyKJAASY0PT6EUg7BBYdlEhPaNLuxAwU8lqu1ElzHv0Ri7EM6irpx5w"; Help would be much appreciated.
  17. Hi, I'm trying to create a Login & Register form which will create a profile for that user but I'm getting a lot of problems and I can't seem to figure out why it's not working correctly? I've created a post on the forums before about this problem but the problem was never resolved, I am new to PHP hence my noobieness. Basicly the problem at the moment is when I try to login it gives me a 'Wrong details error' which is expressed like so: elseif(!mysql_num_rows($r)) { $errorMsg = "* Sorry, couldn't log you in. Wrong login information."; } As far as the register form goes, it works fine to my knowledge as it's adding users to the database when they register and it's encrypting their passwords by using the crypt(); function. I'll link the Login form, the register form and the dbConfig below but I'll replace any sensitive details with '-HIDDEN-' for safety. I would really appreshiate if someone could help me out on this one cause I've been stuck with this problem for quite a while now and I can't figure it out, thanks a lot Register.php <?php include ("dbConfig.php"); if ($_SERVER['REQUEST_METHOD'] == "POST") { $usernameSQL = mysql_real_escape_string($_POST['username']); $emailSQL = mysql_real_escape_string($_POST['email']); $passwordSQL = mysql_real_escape_string($_POST['password']); $passwordSQL = crypt('$password'); $q = "INSERT INTO -HIDDEN-(username, email, password)VALUES('$usernameSQL', '$emailSQL', '$passwordSQL')"; $r = mysql_query($q); header("Location: register.php?op=thanks"); } ?> <form action="?op=reg" method="POST"> Username:<br><font color="red">*</font><input class="GeneralForm" type="text" name="username" id="username" maxlength="20"><br> <br> Email:<br><font color="red">*</font><input class="GeneralForm" type="text" name="email" id="email" maxlength="50"><br> <br> Password:<br><font color="red">*</font><input class="GeneralForm" type="password" name="password" id="password" maxlength="50"><br> <br> <input type="checkbox" name="tick"><font color="gray" size="3"> I agree to the Terms of Use<br> <br> <button type="submit" name="submit" class="InputButton" value="Submit">Submit</button> </form> <br><font size="2" color="gray">* You can edit details on your profile when you login!</font> Login.php <?php session_start(); include "dbConfig.php"; $errorMsg = ""; if ($_GET["op"] == "fail") { $errorMsg = "* You need to be logged in to access the members area!"; } if ($_SERVER['REQUEST_METHOD'] == "POST") { $username = trim($_POST["username"]); $password = trim($_POST["password"]); if (empty($username) || empty($password)) { $errorMsg = "* You need to provide a username & password."; } else { $usernameSQL = mysql_real_escape_string($username); $passwordSQL = crypt('$password'); $q = "SELECT id FROM -HIDDEN- WHERE username='{$usernameSQL}' AND password='{$passwordSQL}' LIMIT 1"; $r = mysql_query($q) or die("Error: " . mysql_error() .

  18. I have been tasked to create a small program in any language I know, which is PHP. It will be a console app (I can't install a LAMP stack etc) and it has to: Allow one of six minibeasts to be selected from a menu Enter and store the name and grid co-ordinates of the selected minibeast Display how often each minibeast was found Display the minibeasts found in each grid co-ordinate So far in PHP I have got a welcome screen, then some of the menu from which they can input what minibeast they want to select information for (sort of). I have the actual menu worked out, it's a simple "echo" after all, but I need to work out how to execute different code based on their input. This is my main file: require_once 'functions.php'; require_once 'config.php'; welcome(); // Adds the welcome message to the program menu(); // Adds the selection menu to the console app getUserInput(); This is functions.php with all my functions: <?php // This holds all of the functions for the // program // Welcome function (just text really) function welcome(){ echo " Welcome to the console application. "; echo " To begin using the program, type a number from the list below and then press \"ENTER\" to execute it. "; echo " For help, type \"help\" and execute it, for credits type \"credits\" and execute and for prog. info type \"info\". Version $vernumber "; } // Next is the selection menu function menu(){ echo " Please execute a number from below: 1. Slug 2. Centipede 3. Ladybird 4. Snail 5. Woodlouse 6. Worm 7. Exit "; } // Add the input catcher function getUserInput(){ fwrite(STDOUT, "Enter your choice\n"); $selected = fgets(STDIN); if ($selected = "1"){ echo "hi"; } elseif($selected = "2"){ } } ?> This is where the problems start. I take their input as $selected, but the if statement is for some reason not working. Then I need to work out how to execute the function again if they enter nothing. Could this be accomplished in a while.. loop? Thanks a lot

  20. I'm having trouble adding text at the end of the latest array chunk, when he has less than 9 elements + counter. Below is my actual code. I use the $txtcontent as text input from a webform. function hexToStr($hex) { $string=''; for ($i=0; $i < strlen($hex)-1; $i+=2) { $string .= chr(hexdec($hex[$i].$hex[$i+1])); } return $string; }[/font][/color] $commas = hexToStr('22'); $format = $_POST['format']; $titre= strtoupper($_POST['titre']); $txtcontent = $_POST['texte']; $txtcontent = wordwrap($txtcontent,20,hexToStr('0D0A'),true); $txtcontent = explode("\n", $txtcontent); $input = array_chunk($txtcontent, 9, false); $i = 1; foreach($input as $key => $array){ $j = 1; $input[$key][0] = "\If S=".$i."\n"; foreach($array as $k => $v){ $input[$key][$k+1] = '\text '.($k*6+1).',1,'.$commas.str_replace(hexToStr('0D'), "", $v).$commas.hexToStr('0D0A'); $j++; } if ($j == 10) $input[$key][10] = "\IfEnd\n"; $i++; } function array_flatten($array) { if (!is_array($array)) { return FALSE; } $result = array(); foreach ($array as $key => $value) { if (is_array($value)) { $result = array_merge($result, array_flatten($value)); } else { $result[$key] = $value; } } return $result; } $array = array_flatten($input); $filecontent = implode($array); header('Content-Type: application/octet-stream'); header('Content-Disposition: attachment;filename='.$_POST['titre'].'.'.$format.''); header('Cache-Control: max-age=0'); //$fh = fopen($filename, 'wb'); $fh = fopen('php://output', 'wb'); fwrite($fh, $filecontent); fclose($fh); Exemple: if i sumbit this content as input in the webform: line1 line2 line3 line4 line5 line6 line7 line8 line9 line10 line11 line12 line13 line14 line15 line16 line17 line18 line19 line20 I will have a file with this content: \If S=1 \text 1,1,"line1" \text 7,1,"line2" \text 13,1,"line3" \text 19,1,"line4" \text 25,1,"line5" \text 31,1,"line6" \text 37,1,"line7" \text 43,1,"line8" \text 49,1,"line9" \IfEnd \If S=2 \text 1,1,"line10" \text 7,1,"line11" \text 13,1,"line12" \text 19,1,"line13" \text 25,1,"line14" \text 31,1,"line15" \text 37,1,"line16" \text 43,1,"line17" \text 49,1,"line18" \IfEnd \If S=3 \text 1,1,"line19" \text 7,1,"line20" But i also need that the latest array chunk contain the text "\ifEnd" at the end, even when he has less than 9 elements + counter (S= X). \If S=1 \text 1,1,"line1" \text 7,1,"line2" \text 13,1,"line3" \text 19,1,"line4" \text 25,1,"line5" \text 31,1,"line6" \text 37,1,"line7" \text 43,1,"line8" \text 49,1,"line9" \IfEnd \If S=2 \text 1,1,"line10" \text 7,1,"line11" \text 13,1,"line12" \text 19,1,"line13" \text 25,1,"line14" \text 31,1,"line15" \text 37,1,"line16" \text 43,1,"line17" \text 49,1,"line18" \IfEnd \If S=3 \text 1,1,"line19" \text 7,1,"line20" \IfEnd Anyone have any suggestions on how to do it?
  21. I got an error in my code and I'm not really sure of what it might be... this is the problem that I get I guess the problem is in the area that I will colour red in the code below. Since that is the 8th row of sql that is initiated I moved the green one to the end of the other row and the number switched from 8 to 7 so it is that code that is red that atm is what I see is the error so if someone could help me with this I would really appreciate it. <?php include '../../php/header2.php'; echo' <!--Mainbody--> <div align="center"class="box">'; echo '<h2>Create a topic</h2>'; if($_SESSION['signed_in'] == false) { echo 'Sorry, you have to be <a href="/forum/signin.php">signed in</a> to create a topic.'; } else { if($_SERVER['REQUEST_METHOD'] != 'POST') { $sql = "SELECT cat_id, cat_name, cat_description FROM categories"; $result = mysql_query($sql); if(!$result) { echo 'Error while selecting from database.

  22. Hi, I am following the PHP Academy tutorial on youtube, and I'm on part 4 (http://www.youtube.com/watch?v=cJJKQ8MXGrE). However, I am running into a bit of a problem as I have other session variables for my user login and when I am using the foreach statement I dont want to include the login session variables if you understand, only the product_ variables function cart() { foreach($_SESSION as $name => $value) { if ($value>1) { if (substr($name, 0, =='product_'){ $id = substr($name, 8, (strlen($name)-); echo '<br />'.$id; } } else { echo "Your cart is empty! <br />"; echo $name.': has a value of :'.$value; } } } and this is displayed: As you can see it's also using the login session variables which is causing some issues for me because it's displaying that the cart is empty when it is not! So i'm a bit stuck as to what to do :S Sam-
