如何通过Ajax数据在codeigniter php函数中获取脚本数组值：

Question

Here is my code :

<script type="text/javascript">
var log;
function send_query(check,datashow) {
var values = [];
for (i = 0; i < check.length; i++) {
    if (check[i].checked == true) {
        values.push(check[i].value);
    }
}
alert(values);
$.ajax({
type:"POST",

 data: {"data=":values},
 // data : $('[data="values[]"]').serialize()   
 // data:{data: $(values).serializeArray()}, 
 //data:"data="+values,
 url:"<?php echo site_url('grocery/add_to_show');?>",
success: function(html){
    $('#'+datashow).html(html);
}
});

in codeigniter controller php function, how to get this script array variable and how to print that array variable?

please show me a way for my problem

Answer 1

Try this...

Script

<script type="text/javascript">
var log;
function send_query(check,datashow) {
var values = [];
for (i = 0; i < check.length; i++) {
if (check[i].checked == true) {
    values.push(check[i].value);
}
}

var jsonString = JSON.stringify(values);

$.ajax({
type:"POST",

data: {data : jsonString}, 

// data : $('[data="values[]"]').serialize()   
// data:{data: $(values).serializeArray()}, 
//data:"data="+values,
url:"<?php echo site_url('grocery/add_to_show');?>",
success: function(html){
$('#'+datashow).html(html);
}
});
}
</script>

In your controller

$data = json_decode(stripslashes($_POST['data']));

Instead of $_REQUEST, you can use $this->input->get_post(). even $this->input->post() should work. it is safer.
