PHP - Response Versus Responder
Is there anything different between a response and a responder? My thought is maybe a response is something that one application gives to another, and a responder is used only by a single application to create a response.
interface TrendInterface
{
public function getResponse($blabla):TrendResponse;
public function getResponder($blabla):TrendResponder;
}
Similar TutorialsA HTTP request is made to the server, Slim creates a Request and Response object, content in the Request is sent to another server using cURL via Guzzle, Guzzle returns its own Response, and content from Guzzle's response must be returned by the original Slim response. Would you recommend white-listing or black-listing response headers, and which specific headers? Similarly, would you recommend white-listing or black-listing the request headers sent via cURL, and which specific headers? Thanks

Html code Code: [Select] <div id="feedback"> <p class="error wrong_name"> Fill the correct name</p> <p class="error wrong_email"> Incorrect email</p> <p class="error wrong_message"> Enter your message</p> </div> <form action="sendemail.php" id="contact_us" method="post"> <p class="label_name">Name</p> <p class="input_form"> <input type="text" name="Name" width="20"/> </p> <p class="label_name">Email</p> <p class="input_form"> <input type="text" name="Email" /> </p> <p class="label_name">Message</p> <p class="input_form" id="textarea"> <textarea name="Message" rows="5" cols="4" id="message_input"></textarea> </p> <p id="submit"> <input type="submit" value="Send" name="submitButton" class="button" /> </p> </form> <p id="success">Your message was sent succesfully!</p> Php code Code: [Select] <?php $mailTo = 'vmoore@minoritybiz.org'; $name = htmlspecialchars($_POST['Name']); $mailFrom = htmlspecialchars($_POST['Email']); $subject = 'Information Request'; $message_text = htmlspecialchars($_POST['Message']); $message = 'From: '.$name.'; Email: '.$mailFrom.' ; Message: '.$message_text; mail($mailTo, $subject, $message); ?> this works real simple I would like to add a auto respond to the person click the submit button. I'm trying to get my php form to send a simple auto responder to the persons email that submitted the form. Something like "Thanks we received your info". I don't know how to integrate that into my existing script. Below are the configurable parts of the php. The form works perfectly ... just want to add the auto respond function. Thanks! _________________________________________________ _________________________________________________ _____ <?php $d = date("m-d-y H:i:s"); /* ************* Begin Configuration ************* */ $relocate = "http://www.xxxxx.com/"; // insert your relocation url here $home = "http://www.xxxxx.com/"; $MOVE_TO_PATH = '/home/content/xxxxx/html/FileUpload/'; $PATH_TO_DIR = 'http://www.xxxxx.com/FileUpload/'; $sender_name = "Order"; $sender_email = "me@xxxxx.com"; $mailheaders = "Content-Type: text/plain; charset=us-ascii\nFrom: $sender_name <$sender_email>\nReply-To: <$sender_email>\nReturn-Path: <$sender_email>\nX-Mailer: PHP"; //$to = "me@xxxxx.com"; $to = "me@xxxxx.com"; $subject = "Order"; $success_block = "<p>Thank you for submitting your information.

In the submission form, users are required to filled in two infos,.. Name and email address. As soon as the 'submit' button is been clicked, the php script should be able to grab the filled infos and stores it on the server in a txt file and at the same time, it should sends out confirmation email to the email address so filled in the submission form. Also, can anyone devise a method as how to retrieve the message body of the confirmation email from the previous php script and then pass it on again to the display of the next page as when the submission button is clicked? Thank you so much in advance. I understand that I can place my HTML code outisde of my PHP tags and have it publish, OR i can put it inside the PHP tags and ECHO every line. Am I correct in thinking that either will provide the same result? Is there an advantage to one method over the other?? When sending data via $_POST for example, I've seen the data get filtered with both mysql_real_escape_string or htmlspecialchars When should you use one or the other? Hy i read the topic about the md5 insecurity and the collision possibility.... And now i have a following question. Is it not MUCH more secure to store the actual password in the DB then the md5 value of it?? Because you with it eliminate the collision possibility of the md5 completely. And I am aware of the possibility that someone could break into my DB but if I am dumb enough to let someone access my db, but that is not an issue. I can always use a 2way encryption to store the data. I initially set up a few VAR items to learn some JS coding.
Then it became apparent that altering the group and entering them into an array would be more effective.
However, my limited knowledge is confusing the situation.
Is there a simple comparison (with proper code and formatting) that someone can provide?
Example: student in the school
info desired: name, age, hair color, eye color
As separate VAR listings I cannot sort by age, so I create an array, but how can I name them student 1, 2, 3 etc. (or do I not want to??).
Hi, I found a tutorial online for a form which used PHP/MySQL and JQuery to submit data. I am making some modifications and the form no-longer submits the data. The problem I have is no errors display so I am not sure where the problem lies. I need to be able to display a success or failure message on the form itself, but this is either not there or not working. The code is below. Code: [Select] <form id="ContactForm" action=""> <p> <label>First Name</label> <input id="FirstName" name="FirstName" class="inplaceError" maxlength="120" type="text" autocomplete="off"/> <span class="error" style="display:none;"></span> </p> <p> <label>Last Name</label> <input id="LastName" name="LastName" class="inplaceError" maxlength="120" type="text" autocomplete="off"/> <span class="error" style="display:none;"></span> </p> <p> <label>User Name</label> <input id="UserName" name="UserName" class="inplaceError" maxlength="120" type="text" autocomplete="off"/> <span class="error" style="display:none;"></span> </p> <p> <label>Email</label> <input id="email" name="email" class="inplaceError" maxlength="120" type="text" autocomplete="off"/> <span class="error" style="display:none;"></span> </p> <p> <label>Website<span>(optional)</span></label> <input id="website" name="website" class="inplaceError" maxlength="120" type="text" autocomplete="off"/> </p> <p> <label>Your message<br /> <span>300 characters allowed</span></label> <textarea id="message" name="message" class="inplaceError" cols="6" rows="5" autocomplete="off"></textarea> <span class="error" style="display:none;"></span> </p> <p class="submit"> <input id="send" type="button" value="Submit"/> <span id="loader" class="loader" style="display:none;"></span> <span id="success_message" class="success"></span> </p> <input id="newcontact" name="newcontact" type="hidden" value="1"></input> </form> <?php require_once("config.php"); /* Configuration File */ class DB{ private $link; public function __construct(){ $this->link = mysqli_connect(DB_SERVER, DB_USER, DB_PASS,DB_NAME); if (mysqli_connect_errno()) exit(); } public function __destruct() { mysqli_close($this->link); } public function dbNewMessage($email,$FirstName,$LastName,$website,$message){ $email = mysqli_real_escape_string($this->link,$email); $FirstName = mysqli_real_escape_string($this->link,$FirstName); $LastName = mysqli_real_escape_string($this->link,$LastName); $UserName = mysqli_real_escape_string($this->link,$UserName); $website = mysqli_real_escape_string($this->link,$website); $message = mysqli_real_escape_string($this->link,$message); mysqli_autocommit($this->link,FALSE); $query = "INSERT INTO contact_me(pk_contact,FirstName,LastName,UserName,email,website,message) VALUES('NULL','$FirstName','$LastName','$UserName','$email','$website','$message')"; mysqli_query($this->link,$query); if(mysqli_errno($this->link)) return -1; else{ mysqli_commit($this->link); return 1; } } }; ?> <?php require_once("db.php"); /* Database Class */ require_once('utils/is_email.php'); /* Email Validation Script */ /* Handle Ajax Request */ if(isset($_POST['newcontact'])){ $contact = new Contact(); unset($contact); } else{ header('Location: /'); } /* Class Contact */ class Contact{ private $db; /* the database obj */ private $errors = array(); /* holds error messages */ private $num_errors; /* number of errors in submitted form */ public function __construct(){ $this->db = new DB(); if(isset($_POST['newcontact'])) $this->processNewMessage(); else header("Location: /"); } public function processNewMessage(){ $email = $_POST['email']; $FirstName = $_POST['FirstName']; $LastName = $_POST['LastName']; $UserName = $_POST['UserName']; $website = $_POST['website']; $message = $_POST['message']; /* Server Side Data Validation */ /* Email Validation */ if(!$email || mb_strlen($email = trim($email)) == 0) $this->setError('email','required field'); else{ if(!is_email($email)) $this->setError('email', 'invalid email'); else if(mb_strlen($email) > 120) $this->setError('email', 'too long!

I switched from one web host to another due to poor hosting performance. Now I'm running into the same issue again -- poor web hosting performance.
My first web host was Hostgator. My current web host is AT&T. I hate the thought of switching to a different web host every month trying to find one that will reliably host my site. Does anyone here have a reliable web host that they use and would recommend?
My question is relative since what is reliable for a simple web site, may not be reliable for one that is more complex. For this reason, I can't simply trust web host reviews.
My website isn't overly complicated, but it's more complex than just basic HTML. It uses a lot of PHP, as well as a MySQL database that only has two small tables. The website uploads and downloads small text files regularly. It also sends E-mail attatchments quite often.
Because I just launched, my website isn't getting a ton of traffic -- about 10 users per day. However, I'm beginning to run into the same problem as before. My web host's server is starting to show itself as being unreliable. As with my first web host, it seems as if it may be due to overcrowding on the shared server.
Do any of you run any moderately complex websites? If so, who do you use for a reliable web host?
I've considered setting up my own server with a LAMP configuration and hosting the site myself. However, I don't know a lot about Linux or Apache, and so would like to avoid this. But because the computer would only be hosting my own website, and no one else's, I have to believe that a LAMP setup would be more reliable than a shared server that is overcrowded.
A reliable web host is really what I'm looking for. But I don't want to keep going down the road of trial and error. If anyone uses a web host that reliably supports their moderately-complex website, then I would love to hear from you. I'm sick of my site failing due to server issues. Like the Duracel commercial says, "It just has to work!"
Please forgive me if you feel that my post doesn't correctly fit the forum category. I tried to figure out which category best fits this topic, but none of them seemed to be perfectly suitable.
Thank you for your time, as well as for any suggestions.
I know that magic __get and __set are invoked automatically when an object is instantiated, but what about stuff like getName() and setName() Code: [Select] class NameClass { private $_name; public function getName() { return $this->_name; } public function setName($value) { $this->_name = $value; } } $someName = new NameClass(); $someName->setName('Bob'); echo $someName->getName(); 1. Could the setName() and getName() just as easily be named something generic like: hotName() coldName() Code: [Select] class NameClass { private $_name; public function hotName() { return $this->_name; } public function coldName($value) { $this->_name = $value; } } $someName = new NameClass(); $someName->coldName('Bob'); echo $someName->hotName(); 2. Also, the setName() and getName() methods must be called manually, right? Unless they are manually called, they just sit there, do nothing, am I correct? Thanks good day dear community, this is a big issue. I have to decide: between native PHP DOM Extension or of simple DOM html parser well i want to parse the site he http://buergerstiftungen.de/cps/rde/xchg/SID-A7DCD0D1-702CE0FA/buergerstiftungen/hs.xsl/db.htm http://buergerstiftungen.de/cps/rde/xchg/SID-A7DCD0D1-702CE0FA/buergerstiftungen/hs.xsl/db.htm I will suggest to use the native PHP "DOM" Extension instead of "simple html parser", since it will be much faster and easier What do you think about this one here...: Code: [Select] $doc = new DOMDocument @$doc->loadHTMLFile('...URL....'); // Using the @ operator to hide parse errors $contents = $doc->getElementById('content')->nodeValue; // Text contents of #content look forward to hear from you best regards db1 Hello All, Just working with PHP's snap v1 functions I can use snmpget fine but snmpset produces the following error; Warning: snmpset() [function.snmpset]: No response from 192.....

Hello All, running into a situation that I have not seen before. I have been seeing in multiple areas of my application that the response received from the server has 2 JSON responses in it. Here is a sample function: private function getCatalogItems(){ $start = ($_REQUEST["start"] == null)? 0 : $_REQUEST["start"]; $count = ($_REQUEST["limit"] == null)? 20 : $_REQUEST["limit"]; $q = "SELECT c.`id`, c.`catalog_number`, c.`long_description`, CONCAT(c.`catalog_number`, ' - ', c.`long_description`) AS `display` FROM catalog c"; if(!empty($_REQUEST['query'])){ $q .= " WHERE c.`catalog_number` LIKE '%".$_POST['query']."%'"; } $q .= " ORDER BY c.`catalog_number` ASC LIMIT ".$start.",".$count; $rs = $this->db->get_results($q); $total = $this->db->num_rows; $buff = '{"total":"'.$total.'","data":'.json_encode($rs).'}'; $this->c->returnJSON($buff); } The "returnJSON" function looks like this. public function returnJSON($json){ $contentType = "application/json; charset=utf-8"; header("Content-Type: {$contentType}"); header("Content-Size: " . strlen($json)); echo $json; } As you can see this simply sets the headers of the response. It has been a real head scratcher. Anyone come across something like this before? How can I receive a response from the server with JSON data, when the function that retrieves the data and returns it to the browser has been completely commented out? I am making an AJAX request for JSON formatted data and for some reason it returns a response when it shouldn't as there is no function? I send off this: <?php $data = "<egateway> <eCardExpiryMonth>01</eCardExpiryMonth> <eCardExpiryYear>04</eCardExpiryYear> <eCardHoldersName>Joe Bloke</eCardHoldersName> <eCardNumber>4444333322221111</eCardNumber> <eCVN>123</eCVN> <eTotalAmount>100</eTotalAmount> </egateway> "; $ch = curl_init(); curl_setopt($ch, CURLOPT_POSTFIELDS, $edata); curl_setopt($ch, CURLOPT_URL, "https://www.example.com/gateway_cvn/testpage.asp"); curl_exec($ch); curl_close($ch); ?> In return, I get the following XML: Code: [Select] <eResponse> <eTrxnStatus>True</eTrxnStatus> <eTrxnNumber>20219</eTrxnNumber> <eAuthCode>123456</eAuthCode> <eReturnAmount>100</eReturnAmount> <eTrxnError>00,Transaction Approved(Test CVN Gateway)</eTrxnError> </eResponse> Is there a way to make it so this does not show, and instead I can make PHP do something like: if (eTrxnStatus == True) {// do stuff}; ? I am making a simple login with jQuery ajax but I have a little problem. I get no response from my loginizer.php . My login page (index.php) contains the following code.
<form action="loginizer.php" onsubmit="return submitForm();" method="post" class="box"> <div id="error" ></div> <input id="matNo" name="matNo" class="input is-link is-rounded" type="text" placeholder="e.g. 2015/1/55852EE"> <input id="password" name="password" class="input is-link is-rounded" type="password" placeholder="********"> <button type="submit" id="submit" name="submit" class="button is-link is-small">Login</button></form>
My loginizer php contains the code:
<?php
if(isset($_POST['submit'])){
require("db.php");
$table="Students";
$pUser=$_POST['matNo'];
$pPass=$_POST['password'];
$sql= $conn->prepare("SELECT * FROM $table WHERE Email=?");
$sql->bind_param("s",$pUser);
$sql->execute();
$result = $sql->get_result();
$row = $result->fetch_assoc();
$user= $row['Email'];
$pass = $row['Password'];
$errMsg="Invalid Credentials";
$errMsg1="username doesn't exist";
$successMsg = "successLogin";
if($result->num_rows < 1)
{
echo json_encode($errMsg1);
exit;
}
elseif($pUser == $user && $pPass !== $pass)
{
echo json_encode($errMsg);
exit;
}
else{
echo json_encode($successMsg);
exit;
}
}
?>
Ans lastly myJquery.js file which contains:
function submitForm()
{
var userid=$("#matNo").val();
var pass=$("#password").val();
if(userid!="" && pass!="")
{
$("#submit").html("Please Wait...");
$.ajax
({
type:'post',
url:'loginizer.php',
data:{
matNo:userid,
password:pass
},
dataType:'json',
success:function(response) {
if(response=="successLogin")
{
window.location.href="dash/home/";
}
else
{
$("#error").html(response);
//alert("Wrong Details");
}
}
});
}
else
{
alert("All details are required");
}
return false;
}
The issue is that I get blank response . If I also change the url in the jQuery/Ajax code to index.php, it comes back with a response consisting of the html of the index.php. If I remove the dataType: 'json', it's still no response.
Thanks for your help in advance!!! |
