Hello, thanks to many great posts in this Forum i managed do create a working script which saves a Form submit to a new page (including a file upload) via AJAX. I still have to questions : 1. Does anyone see a security risk in this script? Its the first time im building something like that. 2. How can i prevent direct access via the url. i would like to throw a Wire404Exception then. I tried if($input->post-name) {...} .. but that gives me a 404 on the AJAX request if the name is left empty , which is not what i want. Thanks for your support! <?php $msg = ['name' => ['error' => 'Kein Name angegeben'], 'vorname' => ['error' => 'Kein vorname angegeben'], 'file' => ['error' => 'Keine Datei hochgeladen'], 'wire' => ['error' => 'Unerwarteter Fehler, bitte nochmal versuchen'], 'success' => ['success' => 'Bestellung erfolgreich abgeschlossen'] ]; //Check if all input fields have Data. Everything will be checked via javascript in the frontend as well. if(empty($_POST['name'])) { echo json_encode($msg['name']); return false; } if(empty($_POST['vorname'])) { echo json_encode($msg['vorname']); return false; } if(!isset($_FILES['doc'])|| $_FILES['doc']['error'] == UPLOAD_ERR_NO_FILE) { echo json_encode($msg['file']); return false; } $uploadPath = $config->paths->assets . "files/tmp_uploads/"; $doc = new WireUpload('doc'); $doc->setMaxFiles(1); $doc->setOverwrite(false); $doc->setDestinationPath($uploadPath); $doc->setValidExtensions(array('pdf', 'jpg', 'png', 'jpeg')); $documents = $doc->execute(); if(!count($documents)) { echo json_encode($msg['wire']); return false; } $np = new Page(); $np->template = $templates->get('new-order'); $np->parent = $pages->get('/bestellungen/'); //Populate fields with sanitized data $np->title = "Neue Bestellung von " . $sanitizer->text($input->post->name); $np->orderName = $sanitizer->text($input->post->name); $np->orderVorname = $sanitizer->text($input->post->vorname); $np->save(); foreach ($documents as $document) { $pathname = $uploadPath . $document; $np->orderFile->add($pathname); unlink($pathname); } $np->save(); echo json_encode($msg['success']); ?>

Hello everyone, i am building a little 'shop-like' element for a clients Homepage (no direct payment) Its my first Approach working with php besides very basic php and Processwire stuff, so i am a litte lost here. I want to use KnockoutJs for getting User Input, process the Data on the Server (pulling actual prices from a page) and send a single JSON Object, which holds all the Data needed for display in the UI back to knockout . The data will be send on every "keyup" in the front end. so i want the "checkout" array to be updated every time. I have some code already and it looks good so far. But obviously, with every ajax request ill get a new object with only the newest data back. <?php // Data comming on every "keyup" $hardMenge = $input->get->entities("hard"); $softMenge = $input->get->entities("soft"); // more to items will follow // Different products to choose from (actual prices will come from pages later) // More Products with different requierements will be added class Softcover { public $menge; public $preis; public function __construct($menge) { $this->menge = $menge; $this->preis = $menge * 10; } } class Hardcover { public $menge; public $preis; public $letter; public function __construct($menge, $letter) { $this->menge = $menge; $this->preis = $menge * 10; $this->letter = $letter; $this->total = $letter * .5 + $this->preis; } } $softy = new Softcover($softMenge); $harty = new Hardcover($hardMenge,2); $checkout = array(); $softOut = array("soft" => array("menge" => $softy->menge, "preis" => $softy->preis)); $hardOut = array("hart" => array("menge" => $harty->menge, "preis" => $harty->preis, "mitGravur" => $harty->total)); if (isset($softy) && ($softy->menge > 0)) { array_push($checkout, $softOut); } if (isset($harty) && ($harty->menge > 0)) { array_push($checkout, $hardOut); } // JSON object back to knockoutJS echo json_encode($checkout); My guess is i might use sessions eg $session here to keep all the data in the "checkout" array, and only refresh relevant parts of it on frontend "keyup"events. How could i use sessions to achieve that? Or is my Approach going nowere and i need to rethink everything? Thanks for helping out.

Thanks for helping out, Zeka!

It works! Thanks. Can anyone explain, why?

Hello, im facing a quite odd problem: when im trying to include a piece of code with $files->include it renders the content, in this case a complete <section> ... </section> correctly, but also an additional "1" after the closing tag. When placing the included code directly in the template all works as aspected. So it has to do something with $files->inlcude, right? Thanks, Gregor

Thanks @LostKobrakai. That solved my problem. I got it working with jquery now. My js above is giving me a "Uncaught SyntaxError: Unexpected end of JSON input" ....

Hello, since hours i am struggeling to get an ajax call to an page field working. i think im doing something fundamentally wrong. The Idea is to load some html markup for larger screen sizes. If i put a .php file with the markup outside the 'site' folder it works fine with a basic XMLHttpRequest. But if i want to have the markup stored in a textfield on my 'settings page' within the template folder i have no success. I tried to follow some tips from this thread as well: my settings.php looks like this: <?php if($config->ajax) { $json = array( 'id' => $page->id, 'title' => $page->title, 'markup' => $page->markup ); echo json_encode($json); return; } and my inline javascript like this ( wrapped in enquire.js): <script type="text/javascript"> enquire.register('screen and (min-width: 700px)', { match: function() { var xhr = new XMLHttpRequest(); xhr.onload = function(){ if(xhr.status === 200){ data = JSON.parse(xhr.responseText); document.getElementById('hero').innerHTML = data.markup; } } xhr.open('GET', 'settings.php', true); xhr.send(null); }, unmatch: function() { } }); </script> <section id="hero"> </section> Like this, i am just getting a 404 , and if i try with a path i get a 403 forbidden. Im entirely confused, maybe someone can help. Thanks a lot.

@horstThanks for the explanation.

The solution @horst posted worked for me. I tried with $id++ at the end as well. But then it did not render anything. Thank you for your support!

Thank you very much for the fast help, both of you. I will test it asap as i am back at my desktop! Have a nice weekend!

Hello everyone, i have written a simple function to render the Navigation for my "Onepager" Here is the code: <?php function renderOnepagenav($onepageroot) { $sections = $onepageroot->children; echo "<ul>"; $id = ''; foreach ($sections as $item) { $id ++; echo "<li><a href='#section-$id'>$item->title</a></li>"; } echo "</ul>"; } Every Sektion is a child-page of home in the backend. It works fine but i would like to add two modifications, where i need your help: 1. i would like to skip the first (child-)page. 2. I would like to add a class only to the first rendered <li> Element. All kind of advice is highly appreciated. Thank you, Gregor

@Robin S thank you for the explanation.

Thank you, thats a good advice. Also the profields multiplier seems good for this kind of task, right?

I got it. The Repeater i just installed does the job. But im still open to other ways to accomplish that, just for getting to know PW better. Thanks

Hello, im porting my first static site to PW and still trying to get my head around all the options and logics..maybe you can help out. I have a simple list (ul>li) of Names on the page, which i want my client to alter at any time. Right now, the only option i see is to create a textfield with the CKEditor. Is there a more more straight foreword way to accomplish this, like creating one field in which my client can put comma separated names, and i loop through this field in the template? I tried to find something like this in the cheatsheet but im still struggling with all the options. Thanks for your help.

$config->paths did the trick. Still a lot to learn. Thanks a lot for the fast and kind support.

@blynx Wow, thanks. ill have a closer look at your function. And yes, i am ffm based

Thanks for the fast support! oh sure, i forgot about the correct arrows writing my post. The curly brackets are giving me the correct path now, thanks for that. I am still i am getting a Warning: file_get_contents(/site/assets/img/icons/vibra.svg): failed to open stream: But the files are there for sure... ill figure that out.. Thanks for the fast support!

Hello everyone, this is my first post here, and i hope its the right place for my question. I am getting started with PW and right now, im trying to bring a existing static Site to PW In this static site i was working with some PHP to import svg code echo file_get_contents("img/icons/ticket.svg") I placed the img folder in the assets folder but now i am having troubles to point at this file using $config->urls->assets i was trying to do something like echo file_get_contents("$config-urls-assets/img/icons/ticket.svg") but of course this fails and as i am not quite good with PHP i do not know how to nest this php to get what i want. I don`t want to use fields to store the svg code, because i need different icons on one page and i do not want to create multiple field for that. Any advice is highly appreciated. Thank you.
