json_encode view returns null - shardas - 08-11-2015
Dear CI Masters,
I don't know if I found a bug or I'm just don't get it.
Jquery makes a post to a CI Controller:
Code:
$.post('/update_uri',{var:val},function(return){
console.log(return);
})The Controller:
PHP Code:
$result['pageX'] = $this->load->view('pageX','',TRUE);
print_r($result); //This will be logged on the client
//OR
echo json_encode($result); //Empty String will be logged
Can somebody confirm this?
Thanks in advance

Use Network Monitor in your browser's developer tools and check if calling url is correct and how does response look like

view returns data as a string
please check "Returning views as data" section in View documentation.

Thanks for your reply. I found the issue by myself. It's because json_encode requires UTF8 string. So this works:
Code:
$result['pageX'] = utf8_encode($this->load->view('pageX','',TRUE));RE: json_encode view returns null - InsiteFX - 08-13-2015
With jQuery you should always use the full path:
PHP Code:
<head>
<script type="text/javascript" charset="utf-8">
//<![CDATA[
var base_url = "<?php echo base_url(); ?>";
var site_url = "<?php echo site_url(); ?>";
// ]]>
</script>
</head>
Then use the base_url or site_url in you jQuery code.

Thanks for this hint. I'm going to change that in my project.
