[SOLVED] array_map | join

[jaymc]

I use array_map on an array

 

after doing that, using join() no longer works

 

Im pretty sure its because the position of the array is at the end

 

I tried to use reset() on the array but that did not work. Any ideas?

internal pointer of the array should have no bearing on it.  Post some code, and also a better description than "it no longer works."

[jaymc]

$_POST = array_map("strip_tags", $_POST);

 

 

$beans = join($_POST);

 

join wont work on $_POST after array_map

 

Note: reset($_POST); did not work

[.josh]

so what do you mean by "won't work?" Other than the fact that you didn't supply the glue so it defaults to '' it should work just fine.  This works fine on my server:

 

<?php
if ($_POST) {
   $_POST = array_map("strip_tags", $_POST);
   print_r($_POST);
  $beans = join($_POST);
  echo "<br/>$beans";
}

?>
<br/><br/>
<form action = '' method = 'post'>
   <input type = 'text' name = 'a'><br/>
   <input type = 'text' name = 'c'><br/>
   <input type = 'text' name = 'd'><br/>
   <input type = 'submit' value = 'submit'>
</form>

 

I get an array of values echoed out with html tags stripped, and then a string of array values with no spaces.

Ok I see the problem. Without array_map("strip_tags", $_POST); everything is fine and this is the print_r of $POST

 

Array
(
    [x] => 2
    [y] => 3
    [list] => Array
        (
            [0] => 23913081
            [1] => 23912398
        )

)

 

With array_map("strip_tags", $_POST); here is the print_r of $_POST

 

 

 

Array
(
    [x] => 2
    [y] => 3
    [list] => Array
)

 

The issue is secondary arrays within a primary array
