Help passing STRING array to PHP

[MiceneSagitter]

Hello everybody, I'm a newby on ExtJs but I've managed to overcome many problems reading forums and posts.

Now I have a little problem using a method POST.....and trying to pass array as params. But the real problem is due to String Array.........I explain...

I have a JsonStore

var store_clienti = new Ext.data.JsonStore({
         url: 's_find_clienti.php',
         root: 'data_root',
         fields: ['id','livello','nome'],
         autoLoad:true,
         autoDestroy: false
         });

Ok, now I made a function like that :

function esporta_griglia(store){
         
         var array_id = new Array();
         var array_livelli = new Array();
         var array_nomi = new Array();

         var i = 0;         
         store.each(function(record){
               array_id[i] = parseInt(record.get('id'));
               array_livelli[i] = record.get('livello');
               array_nomi[i] = record.get('nome');
               i++;
            });

         Ext.Ajax.request({            
            url: 's_prova.php',
            params: {sarray_id:Ext.encode(array_id), sarray_livelli:Ext.encode(array_livelli), sarray_nomi:Ext.encode(array_nomi)}
            method: 'POST',
            success: function(result){
                  window.open('griglia.txt','nuovapagina','width=700,height=600');
            },
                  failure: function() {
                  Ext.Msg.alert('Connection not executed!');
               }
            });

Ok, now the PHP script is this:

<?php
include("../common/common_php_header.php");


$array_id = array();
$array_livelli = array();
$array_nomi = array();






$array_id = json_decode($_POST['sarray_id']);
$array_livelli = json_decode($_POST['sarray_livelli']);
$array_nomi = json_decode($_POST['sarray_nomi']);


$identificatore = fopen("griglia.txt","w");


// Scrivo i dati nel file
fwrite($identificatore, $array_id[0]);
fwrite($identificatore, "---");
fwrite($identificatore, $array_livelli[0]);
fwrite($identificatore, "---");
fwrite($identificatore, $array_nomi[0]);
fclose($identificatore);


?>

What I pass with the encode method is this:

• sarray_id:
  [11,782,588,682,781,683,385,384,263,157,54,60,350,352,386,387,589,70,324,608,193,71,65,413,272,194,393,440,195,273]
• sarray_livelli:
  [3,2,1,0,1,0,1,1,2,3,1,1,1,2,1,2,0,0,2,1,2,0,2,1,0,0,2,2,0,0]
• sarray_nomi:
  ["something","something2","something3","something4",..........and so on]

And the result in the .txt file is this:

11---3---

As you can imagine I've a problem with the array encode/decode methods.

For numeric arrays everything is fine, but with the string array I cannot decode it properly....





Could you please help me with this problem. Any suggest will be useful.

Thanks and sorry for my english....

I use this approach ...

var records = [];
if (data.records.length){
    for (var i = 0; i < data.records.length; i++){
        records.push(
            {
                marc_tag: data.records[i].data.marc_tag,
                marc_info: data.records[i].data.marc_info,
                marc_data: data.records[i].data.marc_data,
                marc_subfields: data.records[i].data.marc_subfields,
                sub_occurrence: 1
            }
        );
    }

    // make call to server with selected ids
    Ext.Ajax.request({
        method: 'POST',
        url: 'index.php/mapper/update_profile/',
        params  : {
            recs: Ext.encode(records)
        },
        success: function() {
        },
        failure: function() {
        }
    });
}



// PHP :: model
function update_profile($file, $recs = NULL)
{
    // code from controller ...here for reference
    $recs = $this->input->get_post('recs', TRUE); // get id list
    $recs = json_decode($recs);

..

    // no need to set table name, insert perform this
    if ($recs) {
        foreach ($recs as $rec) {
           // perform action here
        }
        return array('success' => TRUE);
    } else { return array('success' => FALSE); }
}

Regards,
Scott.
