  • URL flow when writing a wizard in PHP

    - by Brian
    Hello, I am writing a basic wizard for my web site. It will have 4 steps, and each needs to have its own URL. Each step must first validate a form before moving on. If the form for a given step fails to validate, I don't want the URL to change. But if it passes, I do want it to move on. What is the preferred way to write this? Using javascript alone to validate is not secure enough. I have 2 ideas so far but I don't love either: 1) Post the form to the same script and use a header() redirect to the next step if it passes. 2) Send an ajax post to validate and then use location.href to send user to the next step if it passes. Is there a better way to do this? Thanks, Brian

  • Cake PHP Routing issue

    - by Smickie
    Hi, I need to do some special routing in cake, but can't for the life of me figure it out. I have a shop controller at /shop, the format of the url will be: /shop/:category/:sub_category/:product_slug In the routing I need to send each part of the url to a different action, for example if the url was just /shop/cakes it would go to the category action of shop. However if the url was /shop/cakes/macaroons or /shop/cakes/fairy it would go to the sub category action on the shop controller. And the the same again for /shop/cakes/macaroons/pistachio would go to the product action on the shop controller. How would I go about this in the routing? Something starting with Router::connect('/shop/:category/:sub_category/:product_slug' ... Or am I way off the mark? Thanks.

  • Batch folder of images into grayscale using php

    - by James
    Can anyone spot where I'm going wrong here. It should be creating grayscale copies of images in one folder and saving them in another folder. Could it be to do with the way im referencing the file locations. Folder permissions on both folders are 777 function grayscalecopy($targetfile, $outputfile){ $size = GetImageSize($targetfile); $width = $size[1]; $height = $size[0]; $canvas = imagecreatetruecolor($width, $height); $sourceimage = imagecreatefromjpeg($targetfile); imagefilter($sourceimage, IMG_FILTER_GRAYSCALE); imagecopy($canvas, $sourceimage, 0, 0, 0, 0, $width, $height); imagejpeg($canvas, $outputfile, 95); imagedestroy($sourceimage); imagedestroy($canvas); echo "Converted ".$targetfile." to grayscale as ".$outputfile." ".$width."x".$height."<br/>"; } $serverfiles = glob("artworkimages/thumbs/*.*"); //$numbertocache = count($serverfiles); $numbertocache = 10; for ($i=0; $i<$numbertocache; $i++) { $serverfilesshort=explode("/",$serverfiles[$i]); $serverfilesshort=$serverfilesshort[count($serverfilesshort)-1]; grayscalecopy($serverfiles[$i], "artworkimages/thumbs/grays/".$serverfilesshort); }

  • Call a constructor from variable arguments with PHP

    - by zneak
    Hello guys, I have a function that takes variadic arguments, that I obtain from func_get_args(). This function needs to call a constructor with those arguments. However, I don't know how to do it. With call_user_func, you can call functions with an array of arguments, but how would you call a constructor from it? I can't just pass the array of arguments to it; it must believe I've called it "normally". Thank you!

  • Kohana PHP - Multiple apps with shared model

    - by Josamoto
    I'm using Kohana 3 to create a website that has two applications, an admin application and the actual site frontend. I have separated my folders to have the two applications separated, so the hierarchy looks as follows: /applications /admin /classes /controller /... /site /classes /controller /.... My question is, how I need to go about creating a shared /model folder. Essentially, both the admin and site itself operates on the same data, so the database layer and business logic remains more or less the same. So to me, it makes sense to have a single model folder, sitting outside of the two application folders. Is it possible to achieve the following hierarchy: /applications /model --> Where model sits in a neatly generic location, accessible to all applications /admin /classes /controller /... /site /classes /controller /.... Thanks in advance!

  • PHP manipulating multidimensional array values

    - by Joker
    I have a result set as an array from a database that looks like: array ( 0 => array ( "a" => "something" "b" => "something" "c" => "something" ) 1 => array ( "a" => "something" "b" => "something" "c" => "something" ) 2 => array ( "a" => "something" "b" => "something" "c" => "something" ) ) How would I apply a function to replace the values of an array only on the array key with b? Normally I would just rebuild a new array with a foreach loop and apply the function if the array key is b, but I'm not sure if it's the best way. I've tried taking a look at many array functions and it seemed like array_walk_recursive is something I might use, but I didn't have luck in getting it to do what I want. If I'm not describing it well enough, basically I want to be able to do as the code below does: $arr = array(); foreach ($result as $key => $value) { foreach ($value as $key2 => $value2) { $arr[$key][$key2] = ($key2 == 'b' ? $this->_my_method($value2) : $value2); } } Should I stick with that, or is there a better way?

    I have this function: function coin_matrix($test, $revs) { $coin = array(); for ($i = 0; $i < count($test); $i++) { foreach ($revs as $j => $rev) { foreach ($revs as $k => $rev) { if ($j != $k && $test[$i][$j] != null && $test[$i][$k] != null) { $coin[$test[$i][$j]][$test[$i][$k]] += 1 / ($some_var - 1); } } } } return $coin; } where $test = array( array('3'=>'1','5'=>'1'), array('3'=>'2','5'=>'2'), array('3'=>'1','5'=>'2'), array('3'=>'1','5'=>'1')); and $revs = array('3'=>'A','5'=>'B'); the problem is that when I run it, it returns these errors (notices): Notice: Undefined index: 1 at line 10 Notice: Undefined index: 1 at line 10 Notice: Undefined index: 2 at line 10 Notice: Undefined index: 2 at line 10 Notice: Undefined index: 2 at line 10 Notice: Undefined index: 1 at line 10 which is this line: $coin[$test[$i][$j]][$test[$i][$k]] += 1 / ($some_var - 1); Any suggestion is greatly appreciated! Thanks!

  • Does this PHP function protect against SQL injection?

    I have this function I'm using and I want to be sure that it fully protects against SQL injection attacks: function MakeSafeForQuery($string) { // replace all of the quote // chars by their escape sequence $ret = str_replace("\\","\\\\",$string); $ret = str_replace("'","\\'",$ret); $ret = str_replace("\"","\\\"",$ret); return $ret; } Am I missing anything serious?

    - by Roland
    I have a script that runs once every month and send out stats to clients, now the stats are displayed in normal text and in the shape of a Pie Graph, now if I run the script mannually from the command line all info on the graphs are correct, but when the cron job executes the script the values for the first client are displaying on the graphs of all clients. but the text is correct. I'm using domDocument to build the HTML and PHPMailer to send out the email with the Graphs embedded into the mail also use pChart to generate the Graph My code that generates the PIE graph is below include_once "pChart.1.26e/pChart/pData.class"; include_once "pChart.1.26e/pChart/pChart.class"; // Dataset definition unset($DataSet); $DataSet = new pData; $DataSet->AddPoint(array($data['total_clicks'],$remaining),"Serie1"); if($remaining < 0){ $DataSet->AddPoint(array("Clicks delivered todate","Clicks remaining = 0"),"Serie2"); }else{ $DataSet->AddPoint(array("Clicks delivered todate","Clicks remaining"),"Serie2"); } $DataSet->AddAllSeries(); $DataSet->SetAbsciseLabelSerie("Serie2"); // Initialise the graph $pie = new pChart(492,292); $pie->drawBackground(255,255,254); $pie->LineWidth = 1.1; $pie->Values = 2; // $pie->drawRoundedRectangle(5,5,375,195,5,230,230,230); //$pie->drawRectangle(0,0,480,288,169,169,169); $pie->drawRectangle(5,5,487,287,169,169,169); $pie->loadColorPalette('pChart.1.26e/color/tones-3.txt',','); // Draw the pie chart $pie->setFontProperties("pChart.1.26e/Fonts/calibrib.ttf",18); $pie->drawTitle(140,33,"Campaign Overview",0,0,0); $pie->setFontProperties("pChart.1.26e/Fonts/calibrib.ttf",11); $pie->drawTitle(343,125,"Total clicks : ".$total_clicks,0,0,0); $pie->setFontProperties("pChart.1.26e/Fonts/calibri.ttf",10); if($remaining < 0){ $pie->setFontProperties("pChart.1.26e/Fonts/calibrib.ttf",10); $pie->drawTitle(260,250,"Campaign over-delivered by ".substr($remaining,1)." clicks",205,53,53); $pie->setFontProperties("pChart.1.26e/Fonts/calibri.ttf",10); } $pie->drawPieLegend(328,140,$DataSet->GetData(),$DataSet->GetDataDescription(),255,255,255); $pie->drawPieGraph($DataSet->GetData(),$DataSet->GetDataDescription(),170,150,130,PIE_VALUE,FALSE,50,30,0); $pie->Render("generated/3dpie.png"); unset($pie); unset($DataSet); $mail->AddEmbeddedImage("/var/www/html/stats/generated/3dpie.png","5"); I just can't understand why this only happens when the cronjob runs?
