  Hi all,
  
  it’s possible to pass array as snippet param ?
  Something like this:
  

  [[SomeSnippet? &param=`array(’foo’, ’bar’)

  
  
  If isn’t, exists any alternatives ?
  
  Thank you for any advices and suggestions

  Not sure you can pass an array, but what you can do is pass a comma separated list and turn it into an array in the snippet.
  
  &param=`1,2,3,4`
  
  then in the snippet use explode (or some other equivalent)
  
  explode(",", $param);
  
  then $parem[’0’] will be 1 and $param[’1’] will be 2 etc...

  Try
  
  http://ca.php.net/manual/en/function.json-encode.php
  
  http://ca.php.net/manual/en/function.json-decode.php
  
  You will need: (PHP 5 >= 5.2.0, PECL json >= 1.2.0)

  i need associavite arr

  
  You can do that the same way but will need a foreach loop to build the ass. array:
  
  

  &param=`key,value||key2,value2||key3,value3`

  
  
  then in the snippet...
  
  

  $paramArray = explode("||", $param);
  foreach($paramArray as $p){
      $n = explode(",", $p);
      $paramAssoc[$n['0']] = $n['1'];
  }

  
  
  the output will be:
  
  

  Array ( [key] => value [key2] => value2 [key3] => value3 )

  
  I’ve never used json encode/decode, will look into that option.

  Here’s another way that’s a little simpler. Haven’t tried it but it should work as long as the extra ampersands don’t confuse the parser:
  
  
  

  [[SnippetName? &string=`Color1=Red&Color2=Blue&Color3=Green`]]

  
  
  

  ColorArray= array();
  parse_str($string,$ColorArray);

  
  
  I think you could also put the code that defines the array into the parameter and use eval() on it.

  You can also store an array value to a placeholder in one snippet and access it in another by name; just make sure the snippet which assigns the value is getting executed first.
