Pass java script unicode array - php

Question

I am storing the unicode values in java script array but when I pass it to the ci controller it is not showing in proper language.
How to pass javascript unicode array to php using form post?
My code is:-
var myTableArray = [];
$("table#search_result_table tr").each(function() {
var arrayOfThisRow = [];
var tableData = $(this).find('td');
if (tableData.length > 0) {
tableData.each(function() { arrayOfThisRow.push($(this).text()); });
myTableArray.push(arrayOfThisRow);
}
});
var myJSON = JSON.stringify(myTableArray);
$.post("<?php echo base_url("Purchase/addnew"); ?>",{data:
myJSON},$("#purform").serialize(),function(data)

Santosh, to post Unicode Array through AJAX and JSON, you need 3 files i.e. Javascript file, html file and a php file. Below is the samle code,
JS file
// make the AJAX request
// #dataform : it is a html data form id
var dataString = $('#dataform').serialize();
$.ajax({
type: "POST",
url: 'php_file.php',
data: dataString,
dataType: 'json',
success: function (data) {
if (data.success == 0) {
var errors = '';
if (data.err_msg != '')
alert('Error');
}
else if (data.success == 1) {
alert('Success');
}
},
error: function (x,e) {
alert('Error: '+x.status+','+x.responseText);
}
});
HTML file
<form id="dataform" name="dataform" method="post" action="" role="form">
<input type="text" name="field1" id="field1" />
<input type="text" name="field2" id="field2" />
<input type="text" name="field3" id="field3" />
<input type="text" name="field4" id="field4" />
<button type="button" name="submit" id="submit" onclick="return false;">Submit</button>
</form>
PHP file
$field1=$_REQUEST["field1"];
$field2=$_REQUEST["field2"];
$field3=$_REQUEST["field3"];
$field4=$_REQUEST["field4"];
//Your Validation Logic
$return_array = validate($field1);
if($return_array['success'] == '1') {
//Your SQL Query //
}
function validate($field1)
{
$return_array = array();
$return_array['success'] = '1';
$return_array['err_msg'] = '';
//Validate Field Logic
if($field1=='')
{
$return_array['success'] = '0';
$return_array['err_msg'] = 'Field1 is required!';
}
return $return_array;
}
header('Content-type: text/json');
echo json_encode($return_array);
die();
