Php: Possible to Automatically Get All Posted Data

PHP: Possible to automatically get all POSTed data?

Sure. Just walk through the $_POST array:

foreach ($_POST as $key => $value) {
    echo "Field ".htmlspecialchars($key)." is ".htmlspecialchars($value)."<br>";
}

Get all variables sent with POST?

The variable $_POST is automatically populated.

Try var_dump($_POST); to see the contents.

You can access individual values like this: echo $_POST["name"];

This, of course, assumes your form is using the typical form encoding (i.e. enctype=”multipart/form-data”

If your post data is in another format (e.g. JSON or XML, you can do something like this:

$post = file_get_contents('php://input');

and $post will contain the raw data.

Assuming you're using the standard $_POST variable, you can test if a checkbox is checked like this:

if(isset($_POST['myCheckbox']) && $_POST['myCheckbox'] == 'Yes')
{
     ...
}

If you have an array of checkboxes (e.g.

<form action="myscript.php" method="post">
  <input type="checkbox" name="myCheckbox[]" value="A" />val1<br />
  <input type="checkbox" name="myCheckbox[]" value="B" />val2<br />
  <input type="checkbox" name="myCheckbox[]" value="C" />val3<br />
  <input type="checkbox" name="myCheckbox[]" value="D" />val4<br />
  <input type="checkbox" name="myCheckbox[]" value="E" />val5
  <input type="submit" name="Submit" value="Submit" />
</form>

Using [ ] in the checkbox name indicates that the selected values will be accessed by PHP script as an array. In this case $_POST['myCheckbox'] won't return a single string but will return an array consisting of all the values of the checkboxes that were checked.

For instance, if I checked all the boxes, $_POST['myCheckbox'] would be an array consisting of: {A, B, C, D, E}. Here's an example of how to retrieve the array of values and display them:

  $myboxes = $_POST['myCheckbox'];
  if(empty($myboxes))
  {
    echo("You didn't select any boxes.");
  }
  else
  {
    $i = count($myboxes);
    echo("You selected $i box(es): <br>");
    for($j = 0; $j < $i; $j++)
    {
      echo $myboxes[$j] . "<br>";
    }
  }

PHP: Possible to automatically get all POSTed data And Multiple checkbox unchecked?

Only "successful" controls are submitted. An unchecked checkbox or radio button is not "successful".

You need to declare a default value with a hidden input. Make sure the hidden input comes before the checkbox so if the checkbox is checked it will override the default hidden input since the names are the same:

<input name="p-sis-0110-1" type="hidden" value="0">
<input name="p-sis-0110-1" type="checkbox" value="1">

To use an array you need to explicitly define the indexes so they are the same:

<input name="input[0]" type="hidden" value="0">
<input name="input[0]" type="checkbox" value="1">

How can I get all posted data as one single line in php?

I don't quite understand what you want, but I think you're looking for the following:

On a single line:

$raw_data = file_get_contents("php://input");

in an array

$array_data = $_POST // this is already an array?

How can I use $POST in PHP to automatically collect data from HTML5 inputs and send through e-mail?

You can try like this:

$body="";
foreach ($_POST as $key => $value) {
    $body.= str_replace("_"," ",$key).": ". $value."\n";
}

provided that $key holds the descriptive information which you need with words separated by underscore (_) as in your question is.

How do I print all POST results when a form is submitted?

All the values are stored in the $_POST collection

<?php print_r($_POST); ?>

or if you want something fancier that is easier to read use a foreach loop to loop through the $_POST collection and print the values.

<table>
<?php 

    foreach ($_POST as $key => $value) {
        echo "<tr>";
        echo "<td>";
        echo $key;
        echo "</td>";
        echo "<td>";
        echo $value;
        echo "</td>";
        echo "</tr>";
    }

?>
</table>

How to grab all variables in a post (PHP)

If you really just want to print them, you could do something like:

print_r($_POST);

Alternatively, you could interact with them individually doing something like:

foreach ($_POST as $key => $value) {
    //do something
    echo $key . ' has the value of ' . $value;
}

but whatever you do.. please filter the input. SQL Injection gives everyone sleepless nights.

How can I get all submitted form values in PHP and automatically assign them to variables?

Look at the extract function : http://www.php.net/manual/en/function.extract.php

Posted form data remains in memory

you can force to unset it ,
unset(var) OR unset($_POST['message'])

Is it possible to automatically post a client's form from server side?

When you say "posting a client's form" it does the following things:

1. Initialize form submission with data in the form fields via browser API.
2. Send the POST/GET request to the destination server.

The step 1 can only be done in a client side - because the data is in the browser and PHP has no part in handling the browser when the page is fully loaded.

But step 2 can be done using almost any language and make the destination server record the data via TCP sockets. PHP is just a candidate here.

What your second article does is this.
