PHP - Best Approach To Send Complex Data To The Server
All good with sending single dimensional form data to the server using application/x-www-form-urlencoded, and having PHP convert it into an array. Also, good with sending simple arrays using []. But then I find myself needing to send a deeper object to the server . For example, I have a form with three text inputs simpleFormName 1, 2, and 3 plus some deeper object.
Array
(
[simpleFormName1] => bla
[simpleFormName2] => bla
[simpleFormName3] => bla
[deeperObject] => Array
(
[0] => Array
(
[prop1] => bla
[prop2] => true
[data] => Array
(
[0] => Array
(
[p1] => 321
[p2] => 123
)
[1] => Array
(
[p1] => 121
[p2] => 423
)
[2] => Array
(
[p1] => 221
[p2] => 133
)
)
)
[1] => Array
(
[prop1] => blabla
[prop2] => false
[data] => Array
(
[0] => Array
(
[p1] => 222
[p2] => 443
)
[1] => Array
(
[p1] => 321
[p2] => 213
)
[2] => Array
(
[p1] => 111
[p2] => 421
)
)
)
)
)
I see at least four options: Come up with naming structure which "flattens" the data. I have used this approach in the past, but it quickly becomes difficult to manage and I don't want to do so. Not use PHP's POST and and instead use Content-Type: application/json and file_get_contents(php://input) and json_decode the entire request server side. Use PHP's POST and urlencoding but make deeperObject a string using JSON.stringify and json_decode this one field server side. Urlencode the entire object.simpleFormName1=bla&simpleFormName2=bla&simpleFormName3=bla&deeperObject%5B0%5D%5Bprop1%5D=bla&deeperObject%5B0%5D%5Bprop2%5D=true&deeperObject%5B0%5D%5Bdata%5D%5B0%5D%5Bp1%5D=321&deeperObject%5B0%5D%5Bdata%5D%5B0%5D%5Bp2%5D=123&deeperObject%5B0%5D%5Bdata%5D%5B1%5D%5Bp1%5D=121&deeperObject%5B0%5D%5Bdata%5D%5B1%5D%5Bp2%5D=423&deeperObject%5B0%5D%5Bdata%5D%5B2%5D%5Bp1%5D=221&deeperObject%5B0%5D%5Bdata%5D%5B2%5D%5Bp2%5D=133&deeperObject%5B1%5D%5Bprop1%5D=blabla&deeperObject%5B1%5D%5Bprop2%5D=false&deeperObject%5B1%5D%5Bdata%5D%5B0%5D%5Bp1%5D=222&deeperObject%5B1%5D%5Bdata%5D%5B0%5D%5Bp2%5D=443&deeperObject%5B1%5D%5Bdata%5D%5B1%5D%5Bp1%5D=321&deeperObject%5B1%5D%5Bdata%5D%5B1%5D%5Bp2%5D=213&deeperObject%5B1%5D%5Bdata%5D%5B2%5D%5Bp1%5D=111&deeperObject%5B1%5D%5Bdata%5D%5B2%5D%5Bp2%5D=421 Any recommendations how to best implement? If you recommend using urlencoding for simple forms, but some other approach for more complex data, what criteria do you use to transition from one approach to another?

I'm new to the whole AJAX thing. Hi, For about a month, I have been trying to figure out why my code will not return anything after posting a wwwForm (I have also tried the newer equivalent of this function but I had no luck with that either.) The nameField and passwordField are taken from text boxes within the game and the code used in my login script is copied and pasted from a Register script but I have changed the file location to the login.php file. The register script works fine and I can add new users to my database but the login script only outputs "Form Sent." and not the "present" that should return when the form is returned and it never gets any further than that point meaning that it lets the user through with no consequence if they use an invalid name because the script never returns an answer. What should I do to fix this? Thanks, Unity Code:

My question is, how can I update table on site B, when I send request for updating on site A. Basicly, I need to transfer value from site A, and site B should receive this value, and update table. How can I do it, what do I need? Hello i m newbie to PHP. I am trying to host the website on my laptop but due to some configuration i cant send the emails through php script. I am trying send mail through mail() but not able to sent mail. heres the code: $to = "jwalant.baria@gmail.com"; $subject = "Hi!"; $body = "Hi,\n\nHow are you?"; if (mail($to, $subject, $body)) { echo("<p>Message successfully sent!</p>"); } else { echo("<p>Message delivery failed...</p>"); } Output: Message delivery failed.. I read the previous post here. but I am not able to figure out what to do about it. Can anyone tell me what setting i do in my php.ini? or any other that necessary settings require for this. i don't have SMTP server on my laptop so is there any method from which i can setup the SMTP server on laptop.? I use apache HTTP 2.2 and PHP 5.3.4 Rest of the website working correctly but only mail not working. TY..!! Hello! I have sim card, how can we integrate it with server and use web interface to send sms and other requests, all handled via PHP?? Just an idea will be appreciated. thanks watsmyname Hello, I am creating a website with the use of php and mysql. While I am not advanced, I've been learning quite a bit on php. However, I am looking to build a tracker type script and hide it into my coding so that if someone were to hack into my website and take my website coding, that it would send me an email notifying that they were using my coding. How would I go about this? If you can help me, i'd be glad to credit you! Thank you! I wish to create validation rules once which are used both on the client and on the server.
For instance, I will start off with the following PHP object:
stdClass Object
(
[rules] => stdClass Object
(
[email] => stdClass Object
(
[required] => 1
[email] => 1
[remote] => stdClass Object
(
[url] => check-email.php
[type] => post
[data] => stdClass Object
(
[username] => function() {return $( '#username' ).val();}
)
)
)
)
[messages] => stdClass Object
(
[email] => stdClass Object
(
[required] => an email is required
)
)
)
When the edit page is downloaded to the client, I will include this object in some format suitable to the client.
The client will then use the jQuery Validation plugin (http://jqueryvalidation.org/) along with the validation object, and client side validate the page.
When the form passes client side validation and is uploaded, PHP will use the same validation object to serverside validate the form (I have this part working as desired).
My question is how should I pass this data to the client? Originally, I would just use PHP to write some JavaScript.
exit('var myObj='.json_encode($myObj));
Note that when I json_encode the object, the value of $myObj->rules->email->remote->data->username is a string with quotes around it, however, I can easily use PHP to strip these tags before sending it to the client.
As Jacques1 pointed out in http://forums.phpfre...ascript-client/, I should never ever use PHP to generate JavaScript, and should use AJAX to download the JSON directly. I tried doing the later, but found that a callback function could not be included in the JSON.
Please advise on the best way to accomplish this.
Thank you
Hey, I'm trying to send a form input to a page, and then get the response (as in, the body) from that page without leaving my PHP script. So instead of when you normally submit a form and it will take you to the 'action="/somepage"'. I want it to get that information and bring it back to the original page. No navigation should happen. I'm almost certain this is possible, but the only thing I've found at the moment requires a custom addon - which, isn't on most hosting sites. Sorry if I haven't described this very well, but any help would be appreciated Thanks tree ..and its not working (i replaced <textarea> with <div> to apply some html tags inside it ) and this is my form : Code: [Select] <form action="proc.php" method="post"> <div id="text" name="question_text" class="text" contenteditable="true"></div> </form> but when i submit some text the $_POST['question_text'] is not set ! Hello everyone, I am trying to submit a comment in a comment box and send it to the DB but is not happening. The connection is good as I am logging in and all but no data is sent to the DB when I post the comment. It doesn't show in my comment section either.

How to send multipart/form-data ? via curl or so ... here i am going to send it - http://dezend.me/dezend/ Quick question for you guys. I am collecting payment data for a product. Is it possible to send data from my form via http directly into another payment form via the post http headers? So say if i had all the details payment info and address info and i matched my form exactly to theirs. Is it possible to write a php script to send the data from my form directly to another websites form to make an order, say amazon or a big site like this? ?first_name=samuel&last_name=east&action=Submit Any Help? Thanks I am successfully doing this, however, I believe I am doing it wrong. I am currently doing the following. How should I be doing this? My thought is getObject.php should return JSON, not JavaScript, but I don't know how to assign the received JSON to the myObj variable. Thanks Hello, i want to send and receive data from https url. how it can be done in php? Thanks I needed a server side PHP validation script for my form to use on top of client side Javascript as a backup. I found a nice package where I just include the validator and set a few options then it does the rest. However it doesn't seem to work with the action="whateveraction.php" for the form. It will skip all the validation and immediately go to the action script. So I left that blank as you can see in the form below and figured I would send the post data somehow to the script using PHP when the validation is successful. However I am stumped on how to do that can I get some coding help? This is the small validation script. I will attach the formvalidator.php in this post. Code: [Select] <?php require_once "formvalidator.php"; if(isset($_POST['submit'])) { $validator = new FormValidator(); $validator->addValidation("age","req","Please fill in your Age"); $validator->addValidation("mcid","req","Please fill in your Minecraft Username"); $validator->addValidation("description","req","Please fill in a Description"); if($validator->ValidateForm()) { //need something here to have it send the post data to /mcbuildapp/form_submit.php } else { echo "<div class=blockrow><b><font size=5>Form Errors:</font><b></div>"; $error_hash = $validator->GetErrors(); foreach($error_hash as $inpname => $inp_err) { echo "<div class=blockrow><p><font color=red>$inp_err</font></p>\n</div>"; } } } Then the form if it matters.... Code: [Select] <div class="blockrow"> <font size=4><b>Minecraft Building Rights Application</b></font> <br /> <br /> <b>Failing to fill in any of these fields sufficiently will result in an automatic denial of your application!</b><br /> <b>Think of it this way, being lazy and applying wrong is only wasting your time. Take the time to do it correctly the first time.</b> <br /> <br /> <b><font color=red>To ensure proper user authentication and security you must first join the server at least once before applying for your building rights to work!</font></b> <br /> <br /> <form action="" id="mcbuilderapp" name="mcbuilderapp" method="post"> <label><b>Your Minecraft Username (required)</b><br /> Use exact capitalization and punctuation that matches your Minecraft.net account!</label> <br /> <br /> <input type="text" name="mcid" id="mcid" maxlength="25"/> <br /> <br /> <label><b>Your Age (required)</b></label> <br /> <br /> <input type="text" name="age" id="age" maxlength="3"/> <br /> <br /> <label><b>Describe Yourself (required)</b><br /> Describe yourself in <b>no less</b> than 3 sentences using <b>correct grammar</b>.</label> <br /> <br /> <textarea name="description" id="description" minlength="10" maxlength="1000" cols=60 rows=5 wrap="physical"> </textarea> <br /> <br /> <input type="submit" name="submit" value="Submit" /> </form> </div> MOD EDIT: PHP manual tags changed to code tags . . . [attachment deleted by admin] I am retrieving Google Books info in JSON format and displaying it inside a div. I would like to send the contents of this div (name, title, description) to my database using Ajax.
Currently only the ISBN field sends because I have it declared as a variable. However my question is, how do I send the other fields (name, title, author). How do I declare these also, I'm not sure what format they need to be in etc.
My JS
$(document).ready(function() {
$('#submit').click(function(ev) {
ev.preventDefault();
var isbn = $('#isbn_search').val(); //get isbn direct from input
var url='https://www.googleapis.com/books/v1/volumes?q='+isbn;

$.each(data.items, function(entryIndex, entry){
var html = '<div class="results well">';
html += '<h3>' + entry.volumeInfo.title + '</h3>';
html += '<div class="author">' + entry.volumeInfo.authors + '</div>';
html += '<div class="description">' + entry.volumeInfo.description + '</div>';
});
});
});
});
My Ajax;
$.ajax({
type: 'POST',

data: {
'isbn' : isbn,
'title' : title
'subtitle' : subtitle,

Does anyone know if this is possible? Thanks, |
