Pass variable to helper.php

Question

Having a bit of a mind blank at the moment. I have an input field and trying to pass the value of the input when the form is submitted, to a function in the helper.php

default.php

<input name="value" type="text" />
<input name="delete" type="submit" value="submit" />

mod_xxxxxx.php

if(isset($post['delete'])) {
    $delete = $post['value'];
    modXxxxxxxHelper::delete($delete);
}

helper.php

function delete($delete) {
    $value = //get the variable 
}

How can I can the value of the input field which will then define $value ?

Please note that I am using Joomla 2.5 coding standards and therefore $post has already been defined and works correctly

Answer 1

Since you're passing $post['value'] to the method then you can just access that variable using $delete

function delete($delete) {
    // $delete would have the value of $post['value']
}
