[Collection]Snippets Vault[PHP]

Use this format for submitting snippets

It may be used later to parse the snippets to a application (like the one in the VB Section)

If you're going to post a snippet in this thread then you should be posting it in the following format:

Snippet Name: ____________________
Keywords: ____,____,____ ...
Description(Optional): _______________________
Code:

Code:

Your Code Here...

This is to be used for any small bit of code you would like to share.

Why not just make a full site rip of phpclasses? /

Otherwise nice idea, but this section is dead, nobody seems to care about good old web dev

I care, and at some point, all the sections in programming will be alive

hmm, it's been 7 years since your post and this section is still dead as fuck and PHP section is still empty.

Snippets

These snippets are great they help a lot.
gonna add some to notepad++

@NextGen1 wow, thank you DD <3

i'm learning PHP at the moment for my job and it's kinda weiird :S

May I contribute a bit here?, this is a contact form I made for a webpage some while ago.

Snippet Name: My contact form?
Keywords: contact, form, err, is, this, like, bloggin?
Description(Optional): read above :P

Its with AJAX, also, its posted on a blog (not yet, I was just working on it :P) where im user, i wont put the link as I dont want to have the name "spammer" on my head so.

So... we will have these files:

index.php <- Will show up the HTML and that stuff
contactform.js <- Will send the AJAX (also, some stuff with jQuery)
jquery.js <- For effects and that stuff
contactform.php <- Will be the file that will be called by contactform.js
loading.gif <- A gif that will replace the form while the message is sent

We will just use 3 fields, so the code doesnt get messy; Name, email, and message (finally, lol).

Alright so, I would like first to start with index.php file:

Code:

<?php
session_start();
$_SESSION['token']=md5(rand()); // We add this so we get "protected" from bots
?>
<html>
   <head>
      <title>My contact form</title>
      <script type="text/javascript" src="jquery.js"></script>
      <script type="text/javascript" src="contactform.js"></script>
   </head>
   <body>
   <div id="form">
      <p>Name:<input type="text" id="name"></p>
      <p>Email:<input type="text" id="email"></p>
      <p>Message:<textarea id="message"></textarea></p>
      <input type="hidden" value="<?php echo $_SESSION['token']; ?>" id="token">
      <a href="#" id="send">Send</a>
   </div>
   <div id="loading" style="display: none;">
      <img src="loading.gif">
    </div>
   <div id="mess" style="display: none;">
   </div>
   </body>
</html>

Alright, now its time for contactform.js:

Code:

$(document).ready(function(){
    var sending = false;
    // we define the var "sending" so we can check that the user doesnt click the send button many times.
    var showmess = false;
    // this is to hide the "mess" div
    
    $('#send').click(function(){
        // when any item with the id send is clicked;
        if(sending==false){
            if(showmess){
               $('#mess').slideToggle();
               // we hide it.
            }
            // we check that the "form" isnt beeing "submited"
            sending = true;
            var name = $('#name').val();
            var email = $('#email').val();
            var message = $('#message').val();
            var token = $('#token').val();
            // we take the vals from the inputs (also, the token so we can verify it on contactform.php)
            var send = jQuery.parseJSON('{"name":"'+name+'","email":"'+email+'","message":"'+message+'","token":"'+token+'"}');
            // "prepare" the Json
            $.ajax({
                 type: "POST",
                 url: "contactform.php",
                 data: send,
                 dataType: "json",
                 beforeSend: function(obj){
                    // before send, we will want to slide the div with ID form, and show the loading one (wich is actually hidden)
                     $('#form').slideToggle();
                     $('#loading').slideToggle();
                 },
                 success: function(json){
                    // we check here what we got from the server side, and depending on what happened, what we will show.
                     $('#loading').slideToggle();
                     if(json.status==1){
                         $('#form').html('Message sent.');
                         $('#form').slideToggle();
                     }else{
                        showmess = true;
                         $('#form').slideToggle();
                         sending = false;
                         $('#mess').html(json.message);
                         $('#mess').slideToggle();
                     }
                 }
            });
        }
    });
});

Now contactform.php:

Code:

<?php
// we start the session and get the headers for the "return"
session_start();
header('Cache-Control: no-cache, must-revalidate');
header('Expires: Mon, 10 Jul 2000 02:00:00 GMT');
header('Content-type: application/json');

// we add this, as im running this script on my localhost, it takes ms to load and i cant see the js effects
sleep(1);

if(!isset($_SESSION['token'])){
// if token isnt there, then.. probably, a bot, or someone trying to play around, we show him what we got!
    die();
}else{
// if not.. then we check that the token we got from the html, is the same that we got in the session
    $token = isset($_POST['token'])? $_POST['token'] : '';
    if($token != $_SESSION['token']){
// if its not the same, then we kick him back.
        $return['status'] = 0;
        $return['message'] = 'Invalid token.';
        echo json_encode($return);
        die();
    }else{
// but if not, we start getting the variables via POST (the json did this possible)
        $name = isset($_POST['name'])? trim($_POST['name']) : '';
        $phone = isset($_POST['phone'])? trim($_POST['phone']) : '';
        $email = isset($_POST['email'])? trim($_POST['email']) : '';
        $message = isset($_POST['message'])? trim($_POST['message']) : '';
// we get a $return variable, that will be an array (json.message on the js is $return['message'])
        $return = array();
        $return['message'] = '';
        $return['status'] = 0;
// we make some validations
        if(!preg_match('/^[a-zA-ZáéíóúÁÉÍÓÚÀÈÌÒÙàèìòù ]{2,20}$/', $name)){
            $return['message'].='Name\'s not valid!.<br>';
        }
        
        if(!filter_var($email, FILTER_VALIDATE_EMAIL)){
            $return['message'].='Invalid email.<br>';
        }
        
        if(strlen($message)<10 || strlen($message)>500){
            $return['message'].='Invalid message.';
        }
// if $return['message'] == '', means that theres no errors; we send the message
        if($return['message']==''){
// $to would be changed by the email u want the mail to head.
            $to = 'my@Email.com';
// well.. the rest of it.. read about mail() function lol.
            $title = 'New message';
            $mess = '<html><head></head><body>' .$name . ' sent a message, the email is: '.$email.'.'.'<br>Message was:<br>'.$message.'</body></html>';
            $headers  = 'MIME-Version: 1.0' . "\r\n";
            $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
            $headers .= 'From: w.e' . "\r\n" . 'Reply-To: ' . $email . "\r\n";
            @Mail($to,$title,$mess,$headers);
            $return['status'] = 1;
        }
        
// and now, we do an echo with the encoded json of $result, then die.
        echo json_encode($return);
        die();
    }
}

Im guessing i dont need to post the entire jquery.js code, so, im just gonna attach the code working (just tested it, again

)

Cheers!

BTW: on my localhost it will say Message sent, even if it wasnt, as im using @ in the mail function, it wont show me that it couldnt do it...

I knocked up a few tutorials for my old Comp Sci teacher not long ago - these are more advanced than what's covered here - simple database interaction and object-oriented PHP. Hope it is of use...

	$xml = new ArrayToXML;
	$xml->parseXML($array, 'result');
		
	return $xml->render();
?>
