PHP - Form Data To Object

How does everyone take data input from an HTML Form and convert it into an Object in OOP?

I am thinking it would be better if user inputs resided in an object so that I could manipulate the data in OOP terms instead of referencing the Form procedurally.

Hello, I have coded a contact form in PHP and I want to know, if according to you, it is secure! I am new in PHP, so I want some feedback from you.

Moreover, I have also two problems based on the contact form. It is a bit complicated to explain, thus, I will break each of my problem one by one.

FIRST:The first thing I want to know, is if my contact form secure according to you:

The HTML with the PHP codes:

Code: [Select]
<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {

//Assigning variables to elements
$first = htmlentities($_POST['first']);
$last = htmlentities($_POST['last']);
$sub = htmlentities($_POST['subject']);
$email = htmlentities($_POST['email']);
$web = htmlentities($_POST['website']);
$heard = htmlentities($_POST['heard']);
$comment = htmlentities($_POST['message']);
$cap = htmlentities($_POST['captcha']);

//Declaring the email address with body content
$to = 'alithebestofall2010@gmail.com';
$body ="First name: '$first' \n\n Last name: '$last' \n\n Subject: '$sub' \n\n Email: '$email' \n\n Website: '$web' \n\n Heard from us: '$heard' \n\n Comments: '$comment'";

//Validate the forms
if (empty($first) || empty($last) || empty($sub) || empty($email) || empty($comment) || empty($cap)) {
echo '<p class="error">Required fields must be filled!</p>';
header ('refresh= 3; url= index.php');
return false;

} 
elseif (filter_var($first, FILTER_VALIDATE_INT) || filter_var($last, FILTER_VALIDATE_INT)) {
echo '<p class="error">You cannot enter a number as either the first or last name!</p>';
return false;
} 
elseif (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
echo '<p class="error">Incorrect email address!</p>';
return false;
}
elseif (!($cap === '12')){
echo '<p class="error">Invalid captcha, try again!</p>';
return false;
}
else {
mail ($to, $sub, $body);
echo '<p class="success">Thank you for contacting us!</p>';
}
}
?>
<form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post">
<p>Your first name: <span class="required">*</span></p>
<p><input type="text" name="first" size="40" placeholder="Ex: Paul"/></p>

<p>Your last name: <span class="required">*</span></p>
<p><input type="text" name="last" size="40" placeholder="Ex: Smith"/></p>

<p>Subject: <span class="required">*</span></p>
<p><input type="text" name="subject" size="40" placeholder="Ex: Contact"/></p>

<p>Your email address: <span class="required">*</span></p>
<p><input type="text" name="email" size="40" placeholder="Ex: example@xxx.com"/></p>

<p>Website:</p>
<p><input type="text" name="website" size="40" placeholder="Ex: http//:google.com"/></p>

<p>Where you have heard us?: <span class="required">*</span></p>
<p><select name="heard">
<option>Internet</option>
<option>Newspapers</option>
<option>Friends or relatives</option>
<option>Others</option>
</select></p>

<p>Your message: <span class="required">*</span></p>
<p><textarea cols="75" rows="20" name="message"></textarea></p>

<p>Are you human? Sum this please: 5 + 7 = ?: <span class="required">*</span></p></p>
<p><input type="text" name="captcha" size="10"/></p>

<p><input type="submit" name="submit" value="Send" class="button"/>
<input type="reset" value="Reset" class="button"/></p>
</form>

SECOND PROBLEM:If a user has made a mistake, he gets the error message so that he can correct! However, when a mistake in the form occurs, all the data the user has entered are disappeared! I want the data to keep appearing so that the user does not start over again to fill the form.

THIRD: When the erro message is displayed to notify the user that he made a mistake when submitting the form, the message is displaying on the top of the page. I want it to appear below each respective field. How to do that? In JQuery it is simple, but in PHP, I am confusing!

There are two pieces to this- The HTML Form and the resulting php. I can't seem to make the leap, from the code to having the form produce the php page so others can view it until the form is again submitted overwriting the php, thus generating new content.

The environment I am working in is limited to IIs 5.1 and php 5.2.17 without mySQL or other DB

I'm new to php, this isn't homework,or commercialization,  it's for children.  I am thinking perhaps fwrite / fread but can't get my head around it.

Code snipets below. Any help, please use portions of this code in hopes I can understand it

Thanks

How do I get the Form data to save to the php page for others to view?

Hey all,

I want to have an object that has a property which is an object containing instances of other objects. I try this:
Code: [Select]
class Blog extends Posts {
public $has_posts;

public function __construct($a,$b,$c){
$has_posts = (object) array_merge((array) $a, (array) $b, (array) $c);
}
}

class Posts {
public $b;

public function __construct($b){
$this->b = $b;
}
}

$post1 = new Posts(1);
$post2 = new Posts(2);
$post3 = new Posts(3);

$blog = new Blog($post1,$post2,$post3);
var_dump($blog->has_posts); //null
foreach($blog->has_posts as $post){ //Invalid argument supplied for foreach()
echo $post->b;
}

But as you see, has_posts is null, not an object containing other objects.

Thanks for response.

I'm teaching myself how to use php and mysql...

I created a form to insert data into a mysql database, all went well and when I returned to the form it was blank.

I then asked a friend to test it out aswell and when he loaded the form page, the data that entered before him was displayed? (it was still filled out with my info). Even after he refreshed it was still there...

Hows this possible? How would I clear the form after its been submitted if it doesnt do it automatically?

Thanks
Drew

..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 !

Hi People.

I am having a problem with this form and for the life of me can't see where I have made the mistake.

On line 33 I have commented where I get the problem. 

If I remove this line (or comment it out) and remove the insert statements for that line then it all works and I can see the php form on my live site.

However, with this in, as it is, I can't see anything, I get a blank page altogether.  Please, can anyone see my mistake?  I have been going over the code now for ages and it's getting late, and I probably am missing something stupid.

Hi everyone!

So, I have recently become interested in the world of webpage design and HTML coding. Thus far, I have created a  few simple HTML webpages, the first of which includes some basic facts and information on the state of NC. Everything has gone rather smoothly for me until this point, but I would now like to incorporate a bit of PHP into my knowledge of web development.

First, I would like to include a form on my NC page that once submitted, goes to a new PHP page displaying the inputted data to the screen.
On the new page, I am attempting to include files: a header and footer.

On my other couple of pages for which I would like to add server side includes.
And lastly, if possible, it would be great if I could learn how to add some additional features like sending e-mails or displaying the date. Any advice or tips on how to go about this would be greatly appreciated!

so here the code that i am confusing the whole month , how can i get it to print out the filtered data

$sql="SELECT COUNT(*) as conflicts
        FROM rental
        WHERE Dispatch < :dropoff AND Dropoff > :dispatch";
$stmt = $pdo->prepare($sql);
$stmt->execute( [ 
                   'dropoff'  => $Dropoff,
                   'dispatch' => $Dispatch
                ]);

im so frustrated on myself that cant do anything

I have html form and verify post data via pgp
how can I save someone data if some one fill incorrect information

I've got a form on my site, with a textbox...and the info is sent to a db.

How would I get the textbox info to be displayed the same as it was entered?

For instance if I put in an address:

11
Street
Town
City
PostCode

It gets displayed like:

11StreetTownCityPostCode

How could I have it so when I press enter it actually adds a <br> or something to the db?

Thanks.
