PHP Return Value from Controller to Ajax - php

Question

I am using a MVC and I have a button that is using an AJAX call to remove an uploaded image on the site.
This is my Model:
public function remove_document($documentID, $documentName)
{
$objData = $this->objDB
-> setStoredProc('attritionRemoveDocument')
-> setParam('documentID', $documentID)
-> setParam('documentName', $documentName)
-> execStoredProc()
-> parseXML();
return $objData->data->response;
}
The response back from this is either true or false.
Here is my controller:
public function deleteFile()
{
// Get the documentID we are removing
$documentID = $this->input->post('documentID');
$documentName = $this->input->post('documentName');
// Check if the file is even there
if (file_exists('./uploads/'.$documentName)){
// Remove file
unlink('./uploads/'.$documentName);
$removeFile = $this->submit_model->remove_document($documentID, $documentName);
return $removeFile;
}
}
And finally, my AJAX Call:
$('[name=deleteDocument]').click(function() {
var documentID = $(this).attr('documentID'),
documentName = $(this).attr('documentName');
//Delete the image
$.ajax({
type: 'POST',
url: '../deleteFile',
dataType: 'xml',
data: {
'documentID': documentID,
'documentName': documentName
},
success: function(msg) {
// On Success, remove the current file section
console.log(msg);
}
});
});
When i echo the $removeFile value in the controller, I see the true/false value however it never makes it to the success function of the AJAX call.
Any ideas?

Answer 1

in Controller
if the result is true
echo "OK"
if the result is false
echo "NO"
in your View and in success part
success: function(msg) {
if(msg=="OK"){
alert("DELETED");
}else{
alert("NOT deleted");
}
Your controller should not return BOOL if you are using it with ajax , Your AJAX call , should control the result by success method .
