trim() function

[Danny620]

i have a function that trims all post data

 

$trimmed = array_map('trim', $_POST);

 

however because i am subminting a post array like

 

[locations] => Array
                (
                    [0] => Oldham
                    [1] => Royton
                    [2] => Delph
                    [3] => Cheadle
                )

 

it gives me an error saying

 

An error occurred in script 'C:\xampp\htdocs\admin\create_listing.php' on line 23: trim() expects parameter 1 to be string, array given 

 

how can i stop this all other data is posted in a string however the locations one is posted in an array

You could use this function to trim multi-dimensional arrays:

<?php
function trimDeep($val)
{
    return (is_array($val)) ? array_map("trimDeep", $val) : trim($val);
}
?>
