Answered retreive $_POST within snippet what is the best way to loop?

I think i must be doing something wrong. i have a snippet which is trying to loop through the form data that is being submitted. using php

$data = '';
foreach($_POST as $key->$value) {

$data .= $key." ".$value;

}

do I need to pass the data to the snippet 1st, or can I call the $_POST from within the snippet?
i guess if i need to pass the data 1st do I need to call the snippet from a chunk?


im basically trying to convert the $_POST array to a string. I could of course use $string = explode(',', $_POST); but i need to format each input box 1st ad prepaire the data for 3rd party crm system.

$_POST is accessible inside snippet. Your code looks OK, i think you can just drop it into a snippet ant then call it in the template or chunk.

hi

thanks your your response. every time i click the form it produces a white screen. possible typo not too sure still looking into it.
i have found another, yet safer way:

$modx = new modX();
$sanitizedRequests = $modx->sanitize($_POST);

then loop the variable (array) $sanitizedRequests

i dont need the snippet to output anything. all im trying to do is sanatize the data and prep it for sending to crm system. just need to return true if sucessfull or false un sucessfull.

looks like modx doesnt like me to loop through arrays

this is the code i have at the moment in 1 snippet

$modx = new modX();
$arr = $modx->sanitize($_POST);
array_pop($arr);
echo "<pre>";
print_r($arr);
echo "</pre>";
$newarray = array();
foreach($arr AS $k->$v) {
$newarray[] = "<FL val='$k'>$v</FL>";
echo $k;
exit;
}

$data = implode(',',$newarray);

var_dump($newarray);
exit;

this works fine outside a modx environment, but for some strange reason modx doesnt like data manipulation i.e creating a new array from an original array. the $arr prints the array out fine, yet the $newarray is none existant when var_dumping it out to the screen. very strange

and $data= NULL

tried different code, but still no joy. does modx restrict the use of php commands?

outside modx this works fine, in a snippet when executing just shows a white screen, nothing outputted to the screen.

$modx = new modX();
$arr = $modx->sanitize($_POST);
$newarray[0] = '<Leads><row no="1"><FL val="Lead Source">Web</FL>';
array_pop($arr);
foreach($arr AS $k->$v) {
$ne = "<FL val='$k'>$v</FL>";
array_push($newarray, $ne);
}

$data = implode(',',$newarray);

var_dump($data);
exit;

im wondering if this system error has anything to do with it. seem to get this error when i refresh the page.

what about this in a snippet:
