Adding an element to an array depending on user input

[drewgun]

I want to add an element to an array depending on the input of a user...

 

I have no idea how to approach this but this is what I have so far...

 

<?php

$array[]

array_push($array, $add_element);

 

$input = $_POST["input"];

 

if ($input == "blah") {

        $add_element = "blahblahblah";

}

?>

 

The problem with this was that instead of adding a new element for each imputed "blah" the element would just change.

 

I'm obviously new at this and am completely lost. Any help is greatly appreciated.

This must not be all of your code I guess? But wouldn't you want

 

array_push($array, $add_element);

 

to be after

 

if ($input == "blah") {
        $add_element = "blahblahblah";

 

?

Using the function you specified

 

<?php

$input = $_POST['input'];

$array = array();

if ($input == 'add_element')
{
$add_element = 'add_element_val';

$array = array_push($array, $add_element);
}

?>

 

Or you could simply add onto the end of the array like so

 

<?php

$input = $_POST['input'];

$array = array();

if ($input == 'add_element')
{
$add_element = 'add_element_val';

$array[] = $add_element;
}

?>
