PHP parse array posted from jQuery - php

Question

I have this jQuery code that adds to an array inside an $each loop:
new_edit = {};
new_edit['file_id'] = $file_id;
new_edit['file_realname'] = $new_file_realname;
new_edit['file_folder'] = $new_file_folder;
new_file_edits.push(JSON.stringify(new_edit));
jQuery new_file_edits array output
{"file_id":"1857","file_realname":"dddd[1].mp4","file_folder":"/"},
{"file_id":"1856","file_realname":"aaaa[1].jpg","file_folder":"/"},
{"file_id":"1855","file_realname":"ssss[1].jpg","file_folder":"/"}
and im trying to post it to call.php like this:
$.ajax({
type: "POST",
url: "/call.php",
data: "edit_files="+ arrayVarHere,
contentType: "application/x-www-form-urlencoded;charset=UTF-8",
success: function(msg){
alert(+msg);
}
});
In the PHP file call.php i have this code:
if(isset($_POST['edit_files'])){
$edit_array = $_POST['edit_files'];
$file_array = array();
foreach($edit_array as $key => $value){
$file_array[$key] = $value;
}
print_r($file_array);
die();
}
but i get this error and i cant figure out how to fix it, been googling it for a while now...
error:
Warning: Invalid argument supplied for foreach() in /home2/dddd/public_html/call.php on line 237
Line 237: foreach($edit_array as $key => $value){
Any help is much appreciated!

EDIT 1:
I changed $edit_array = $_POST['edit_files']; to $edit_array = array($_POST['edit_files']);
And now it outputs:
{"file_id":"1857","file_realname":"dddd[1].mp4","file_folder":"/"},
{"file_id":"1856","file_realname":"aaaa[1].jpg","file_folder":"/"},
{"file_id":"1855","file_realname":"ssss[1].jpg","file_folder":"/"}
How do i go from here with the foreach($edit_array as $key => $value){ part?
Edit 2:
i build my arrayVarHere like this:
$.each( $selected_files_array, function( index, value ){
//i get $file_id, $new_file_realname and $new_file_folder with some code here
new_edit = {};
new_edit['file_id'] = $file_id;
new_edit['file_realname'] = $new_file_realname;
new_edit['file_folder'] = $new_file_folder;
arrayVarHere.push(JSON.stringify(new_edit));
});

Answer 1

change your code like this:
data: "edit_files="+ arrayVarHere,

Answer 2

call json data by json_decode in call.php
if(isset($_POST['edit_files'])){
$edit_array = json_decode($_POST['edit_files'],true); //return array
$file_array = array();
foreach($edit_array as $key => $value){
$file_array[$key] = $value;
}
print_r($file_array);
die();
}
in your ajax alert should be
success: function(msg){
alert(msg); //remove plus sign ,this can output `NaN`
}

Answer 3

check edit_array is array print_r($edit_array);
check contentType is used form data then correct otherwise used json type
if form data then check data: edit_files[]: arrayVarHere,

Answer 4

It returns this array
Array ( [0] => [{"file_id":"1857","file_realname":"aq53pop_460sv[1].mp4","file_folder":"/"},{"file_id":"1859","file_realname":"aKqbD8Q_460sv[1].mp4","file_folder":"/"},{"file_id":"1856","file_realname":"aDopymK_700b[1].jpg","file_folder":"/"}] )
how can i loop the array and access file_id value etc?

Answer 5

The way you are passing Data to PHP may not be that ideal. Here is what might get you started:
PHP: call.php
<?php
$data0 = isset($_POST['data_0']) ? json_decode($_POST['data_0'], true) : null;
$data1 = isset($_POST['data_1']) ? json_decode($_POST['data_1'], true) : null;
$data2 = isset($_POST['data_2']) ? json_decode($_POST['data_2'], true) : null;
$arrData = array(
'data0' => $data0,
'data1' => $data1,
'data2' => $data2,
);
foreach($arrData as $dataKey=>$dataObject){
$tempFileID = $dataObject->file_id;
$tempFileName = $dataObject->file_realname;
$tempFileFolder = $dataObject->file_folder;
// DO SOMETHING WITH THESE DATA AND THEN BUILD UP A RESPONSE FOR AJAX + SEND IT...
// UNCOMMENT TO SEE THE DATA IN YOUR NETWORKS CONSOLE BUT
// IF YOU DO THIS (SINCE YOU EXPECT JSON RESPONSE) YOUR AJAX WILL RESPOND WITH AN ERROR...
// var_dump($dataObject);
}
// RESPOND WITH THE SAME DATA YOU RECEIVED FROM AJAX: JUST FOR TESTING PURPOSES...
die( json_encode($arrData));
?>
JAVASCRIPT: BUILDING THE DATA FOR PHP
<script type="text/javascript">
var dataForPHP = {};
var iCount = 0;
$.each( $selected_files_array, function( index, value ){
var keyName = "data_" + iCount;
new_edit = {};
new_edit['file_id'] = $file_id;
new_edit['file_realname'] = $new_file_realname;
new_edit['file_folder'] = $new_file_folder;
dataForPHP[keyName] = new_edit;
iCount++;
});
</script>
JAVASCRIPT: AJAX REQUEST
<script type="text/javascript">
$.ajax({
type : "POST",
url : "/call.php",
datatype : "JSON",
data : dataForPHP,
contentType: "application/x-www-form-urlencoded;charset=UTF-8",
success: function(msg){
if(msg){
alert("Ajax Succeeded");
console.log(msg);
}
}
});
</script>
