Thank you very much. This was obviously my mistake. I got a HTTP 400 error with this, but at least it's an error to actually go on.

Apologies, it was further up in the code, I just wanted to post a snippet. $companyName = $_POST['COMPNAME']; $mainContact = $_POST['MAINCONTACT']; $telephone1 = $_POST['TELEPHONE']; $email = $_POST['EMAIL']; $contact2 = $_POST['SECONDCONTACT']; $telephone2 = $_POST['TELEPHONE2']; $email2 = $_POST['EMAIL2']; $package = $_POST['PACKAGE']; The reason for the dollar symbols - the creator of the web service is looking for these. I have tested the output with die("Test: ".$fields_string); and it shows the correct output that I require so I'm thinking it's not a problem with the code?

Hi guys, I was wondering if you could help me. I have this code which should send a call to a RESTful web service (which creates a new user in a database). My code is executing without any errors (that I can see) however the user doesn't get created. $url = 'http://127.0.0.1:85/AccountCreator.ashx'; $curl_post_data = array( '$companyName' =>$companyName, '$mainContact' =>$mainContact, '$telephone1' =>$telephone1, '$email' => $email, '$contact2' => $contact2, '$telephone2' => $telephone2, '$email2' => $email2, '$package' => $package ); foreach($curl_post_data as $key=>$value) {$fields_string.=$key. '=' .$value.'&'; } rtrim($fields_string, '&'); //die("Test: ".$fields_string); $ch = curl_init(); curl_setopt ($ch, CURLOPT, $url); curl_setopt ($ch, CURLOPT_POST, true); curl_setopt ($ch, CURLOPT_POSTFIELDS, $fields_string); $result = curl_exec($ch); curl_close($ch); I'm fairly new to PHP also, so I just can't see where I'm doing wrong. I have access to the server also - is there anything I can check on that which would indicate if the web service is being called or not? I've also read this in http://php.net/manual/en/function.curl-setopt.php... I don't think my PHP document is set to multipart/form-data - Would this affect it? I have also tried it like this with the port number, $url = 'http://127.0.0.1/AccountCreator.ashx'; $curl_post_data = array( '$companyName' =>$companyName, '$mainContact' =>$mainContact, '$telephone1' =>$telephone1, '$email' => $email, '$contact2' => $contact2, '$telephone2' => $telephone2, '$email2' => $email2, '$package' => $package ); foreach($curl_post_data as $key=>$value) {$fields_string.=$key. '=' .$value.'&'; } rtrim($fields_string, '&'); //die("Test: ".$fields_string); $ch = curl_init(); curl_setopt ($ch, CURLOPT, $url); curl_setopt ($ch, CURLOPT_PORT , 85); curl_setopt ($ch, CURLOPT_POST, true); curl_setopt ($ch, CURLOPT_POSTFIELDS, $fields_string); $result = curl_exec($ch); curl_close($ch);

I've just got word from our payment partners, the error was a HTTP 500 error.

Hi, I am trying to post to a REST service using PHP cURL but I'm after running into a bit of difficulty (this being that I've never used cURL before!!). I've put together this code: $url = 'http://127.0.0.1:00/AccountCreator.ashx'; /*Where :00 represents the port number */$curl_post_data = array( 'companyName' =>urlencode($companyName), 'mainContact' =>urlencode($mainContact), 'telephone1' =>urlencode($telephone1), 'email' => urlencode($email), 'contact2' => urlencode($contact2), 'telephone2' => urlencode($telephone2) 'email2' => urlencode($email2); 'package' => urlencode($package) );foreach($curl_post_data as $key=>$value) {$fields_string .=$key. '=' .$value.'&';}rtrim($fields_string, '&');$ch = curl_init();curl_setopt ($ch, CURLOPT, $url);curl_setopt ($ch, CURLOPT_POST, count($curl_post_data));curl_setopt ($ch, CURLOPT_POSTFIELDS, $fields_string);$result = curl_exec($ch);curl_close($ch); I've tried this however it doesn't run. As I am integrating with payment partners, it just says: I have emailed them to find out the exact error, but in the mean time I was wondering could someone take a look at my code to eliminate this as a problem, if possible. Thanks.

Hmm I have tried this function drawHorizontalLine($canvas) { // Create a 1000 x 10 image $canvas = imagecreatetruecolor(1000, 10); // Allocate colors $red = imagecolorallocate($canvas, 255, 0, 0); ImageFilledRectangle($canvas, 0, 0, 1000, 10, $red); // Output and free from memory header('Content-Type: image/jpeg'); imagejpeg($canvas); imagedestroy($canvas); } And then further down in my script I have called drawHorizontalLine($canvas); But I get the 500- Internal Server Error. Is the function okay? I'm thinking it's just the way I'm calling it.

Apologies. I played around with it an awful lot so I was getting a few different errors. Sometimes it was an internal server error 500... Then sometimes it was a mega long text error..but I know this was after I created the drawHorizontalLine function I wasn't including the correct parameters. The code above for that actually draws the red line..would it be possible to include all that into a function e.g. function drawHorizontalLine...and then call it later on in the script?

As in I get a server error and nothing at all displays. I know it's probably just as simple as creating a function, and calling the function somewhere in the script, I'm just not sure where.

Hi guys, new to the forum, also newish to PHP so will surely see you guys often johnnybenimble

Hi everyone, Newish to PHP and I'm sure this is a simple thing but I was hoping someone could help me out. I have a php file that draws a graph for me (it takes in the coordinates from a text file). What I want to do is insert a red line at the top of the graph (not from start to finish, but starting at a certain point in the graph and finishing at another point). This php code achieves the line I would like to insert into the graph: <?php $canvas = imagecreatetruecolor(1000, 10); // Allocate colors $red = imagecolorallocate($canvas, 255, 0, 0); ImageFilledRectangle($canvas, 0, 0, 1000, 10, $red); // Output and free from memory header('Content-Type: image/jpeg'); imagejpeg($canvas); imagedestroy($canvas); ?> I need to insert this into this php script: <?php $width = 1000; //width and height of the resulting image $height = 230; $drawLastLine = false; //draw 9th line or not $testMode = false; //render only 10 images //returns directory with cached images by name of text file function getCacheDirectory($fname) { $mod = filemtime($fname); $dirname = "cache/" . $fname . "." . $mod . "/"; return $dirname; } //checks if specified txt file is cached function isCached($fname) { $dirname = getCacheDirectory($fname); return file_exists($dirname); } //calculated y-coordinates of base-lines for all 9 lines, returns an array function initStart($height, $number = 9) { $d = $number + 1; $t = $height / $d; $res = array(); $c = 0; for ($i = 0; $i < $number; $i++) { $c += $t; $res[$i] = $c; } return $res; } //draws vertical grey line with specified coordinate function drawVerticalLine($img, $x) { $grey = imagecolorallocate($img, 80, 80, 80); $h = imagesy($img); imagesetthickness($img, 3); imageline($img, $x, 0, $x, $h, $grey); imagesetthickness($img, 0.1); } //cuts unfilled part of image in the right, making its width equal to $realW function cutRight($img, $realW) { $h = imagesy($img); $new = imagecreatetruecolor($realW, $h); imagecopy($new, $img, 0, 0, 0, 0, $realW, $h); return $new; } //makes up an array of required colors function allocateColors($img) { $result = array(); $result['blue'] = imagecolorallocate($img, 0, 0, 255); $result['red'] = imagecolorallocate($img, 255, 0, 0); $result['black'] = imagecolorallocate($img, 0, 0, 0); $result['white'] = imagecolorallocate($img, 255, 255, 241); return $result; } //main function which generates all the images function generateImages($fname) { set_time_limit(0); //there's no time limit, because it's long process global $width, $height, $start, $testMode, $drawLastLine; $lines = 9; $start = initStart($height, $drawLastLine ? $lines : $lines - 1); //colors of line from top bo bottom $lineCol = array('blue', 'blue', 'red', 'red', 'blue', 'blue', 'black', 'red', 'red'); $fp = fopen($fname, "r"); //we open our file with data $header = fgets($fp); $curX = 0; $sumX = 0; $imgNum = 1; $colors = false; $const = 1.0; //that's the constant which can be used to multiply by y-coordinates, i.e. making our graphs scalable by y-coordinate $prevY = array(); for ($i = 0; $i < $lines; $i++) { $prevY[$i] = 0; } $dir = getCacheDirectory($fname); mkdir($dir); $img = false; // $maximumImages = 10; //if we are testing, we will do just 10 images, else we will work until the file ends while ((!$testMode || ($testMode && $imgNum < $maximumImages)) && $line = fgets($fp)) { //if it's time to make up a new image if ($sumX % $width == 0) { //we save old one to file if ($img) { imagegif($img, $dir . $imgNum . ".gif"); $imgNum++; } //and create a new one, along with allocating colors and so on $img = imagecreatetruecolor($width, $height); $colors = allocateColors($img); imagefill($img, 0, 0, $colors['white']); $curX = 0; } $data = explode(",", $line); $time = array_shift($data); $linesCount = $drawLastLine ? $lines : $lines - 1; //we loop through our lines for ($i = 0; $i < $linesCount; $i++) { $ly = $data[$i] * $const; //it's the new Y coordinate, and we counts from baseline with y = 0 $realTo = $start[$i] + $ly; //now we count the baseline too $realFrom = $start[$i] + $prevY[$i]; //that's the previous step's y-coordinate $prevY[$i] = $ly; //we remember current coordinate to draw line on next step $x1 = $curX - 1; $y1 = $realFrom; $x2 = $curX; $y2 = $realTo; //we draw line finally with needed color imageline($img, $x1, $y1, $x2, $y2, $colors[$lineCol[$i]]); } //if the time looks like 235.000000, we need to draw vertical line if (round($time) == $time) { drawVerticalLine($img, $curX); } //we increase both curX (which is used for drawing) and overall x (it indicates how much lines we've processed) $curX++; $sumX++; } // if we didn't save all lines to .gifs, we need to save leftovers if ($curX > 0) { $img = cutRight($img, $curX); imagegif($img, $dir . $imgNum . ".gif"); $imgNum++; } //saving numbers of pictures rendered file_put_contents($dir . "info.txt", ($imgNum - 1)); } $fname = $_GET['file']; //there should be no slashes in filename and it should end with .txt if (strpos($fname, "/") !== false || strpos($fname, "\\") !== false || strpos($fname, ".txt") === false) { echo "Security error!"; die; } //it should exist if (!file_exists($fname)) { echo "No such file!"; die; } //if there are no images cached for our file, we need to generate them if (!isCached($fname)) { generateImages($fname); } $page = 1; $dirname = getCacheDirectory($fname); $maxPages = file_get_contents($dirname . "info.txt"); //$maxPages = 10; $uniqid = uniqid(); $img = $dirname . $page . ".gif?" . uniqid(); include("templates/show2.php.inc"); I'm just lost as to how I achive this line in the longer php script. I've tried creating my own function, and then calling it further down but this just breaks it. Any help is appreciated!!
