pass data to $_POST php

Question

Hi,

How can I pass a value/variable to $_POST? Im not getting all data to my php function. So i just figured out to pass them explicitly.

Can anyone tell me how this is done?

Answer 1

Check what's in $_POST and then check your HTML form if it's correct.

print '<pre>';
print_r($_POST);
print '</pre>';

Or you can directly assign value to $_POST as it's (almost) a normal array:

$_POST['test'] = 'hi';

But I suppose that's not what you're looking for.

Answer 2

the $_POST array is used to retrieve the data that has been sent to your PHP page/script with an HTTP POST request.

Are you asking how to explicitly assign values to $_POST without it being automatically assigned in the request? If so, why would you want to do this?

Answer 3

$_POST['value'] = "variable";

Answer 4

If I am reading your question right, you want to pass a value from outside the scope of the function, to inside it's scope, right? This usually is unnecessary when using proper code paradigms in PHP, but you can access a global variable from inside a function using the global keyword.

The global keyword in use:

$test = 1;

function funca() {
    global $test,$foo;
    $test = 2;
    $foo = 8;
}

function funcb() {
    global $test,$foo;
    @echo $test."\n";
    @echo $foo."\n";
}

funcb(); // prints 1 and gives error
funca();
funcb(); // prints 2 and 8
