  1. Hello, I have a problem with all AJAX -requests getting 301 redirect. AFAIK this leads to the POST -data sent with the request getting cleared. Below I is an example about what I'm trying to do. My question is: Is there something I don't understand about Processwire or internet technology which is causing this behaviour?I have page with a button. When you click this button, an HTML overlay popup (done with Foundation and Reveal) with option to enter email is displayed (The content of this popup is a processwire template which is loaded with AJAX -request. Causes also 301 redirect, but this doesn't use POST -data, so I didn't realise the problem at this point) Then this data is sent as POST -request with payload to processwire for processing The processing is done by special API -template, which exists solely for this purpose of processing data. However the payload in the POST -request never reaches the API -template I believe this is because a 301 redirect happens before the the POST -request reaches the API -template Thanks for reading and special thanks for any answers! Example code: Popup (HTML & JavaScript): <!-- use onsubmit to override the standard 'sending form to self' -behaviour <form onsubmit="WEBSITE.dialog.download.mail($('#email').val(), event); "> <label>email:</label> <input id='email' name='email' type='email' value=''> <input type="submit" value="Send"> </from> The function which sends the POST -request to processwire template (which processes API requests) (the function is in separate .js file) // I've translated this from CoffeeScript to JS without testing, hope there's no errors dialog = { download: { mail: function (email, ev){ // Prevent default behaviour of submit -functionality ev.preventDefault(); // Success and error callbacks success = function(response){ console.log('success', response); } error = function(response){ console.log('error', response); } // Do ajax -request with jQuery request = $.ajax({ url: '/api/mailer/send/', method: "POST", data: {email: email}, success: success, error: error }); } } } I've also tried this with doing the request without jQuery, but result is the same. The API template (PHP): ?php // Redirect non-ajax calls // Get the API address from url $api_url = explode('/api/', $page->url); if(!isset($api_url[1])){ // This url is not in correct format, send error die(createJSONResponseError( 1, 'Invalid url format.' ) ); } switch ($api_url[1]): case 'mailer/send/': // This is where it stops every time, though I've checked from Chrome dev console that the email key/value pair exists (at least when request is made) if($input->post->email === null){ die(createJSONResponseError( 2, 'Insufficient params.' ) ); }else{ // Create the response $response = createJSONResponse( 'success', null ); } break; // Default action - needs to be last of the list default: // So this api does not exist, send error die(createJSONResponseError( 1, 'Unknown API.' ) ); break; endswitch; // Send the response die($response); ?> Here's how the responses are created (from a helper methods file): /** * Create JSON response for httpXMLRequest * * @param status - a string that represents the status of this operation. Recommended values: 'success' or 'error' * @param result - the data resulting this request. * * @return JSON object * */ function createJSONResponse($status, $result){ return json_encode( array( 'status' => $status, 'result' => $result ) ); } /** * Create JSON error response for httpXMLRequest * * @param code - error code * @param msg - error message * * @return JSON object * */ function createJSONResponseError($code, $msg){ return createJSONResponse( 'error', array( 'code' => $code, 'msg' => $msg ) ); }
