My html code is like this :
<i class="fa fa-file-pdf-o"></i>
My javascript code is like this :
function showAjaxPdf(file_path)
{
var file_path = file_path.replace(/\\/g,"/");
//example : file_path = assets/images/myfile.pdf
$.ajax({
type: "POST",
data: 'file_path=' + file_path,
url: "news/test",
success: function(response)
{
$('#test').html(response);
}
});
}
My function test in controller :
public function postTest(Request $request)
{
$file_path = $request->input('file_path');
return response()->download($file_path);
}
When I click on the pdf icon, no response.
I wish, when click on the pdf icon, appear like this:
how to keep when click pdf icon, the image appears like it?
Thank you
What I have done is, written two separate route one to verify and one to download.
On success of one ajax I have triggered window.open(downloadUrl,'_blank') to download in separete window.
It is not the way asked but it prevents any upcoming errors as verify url will sort that
$.ajax({
url: verifyUrl,
type: 'get',
cache: false,
data: null,
error: function (err){$('#ajax_loader_div').hide();},
success: function(response) {
console.log(response);
$('#ajax_loader_div').hide();
if (response.status == 'success')
{
window.open(downloadUrl,'_blank');
}else if(response.status == 'error')
{
//show error
}
}
});
for that you need to set the header with response object.
Please see the below code.
$headers = array(
'Content-Type'=> 'application/pdf'
);
$file_path = $request->input('file_path');
//TODO: you have to split the file name from url
return Response::download($file_path, '<filename>', $headers);
I hope this code will help you
return Response::download($file_path, '<filename>', $headers);
It's return response, not download file!

I need to send mail to user after downloading .csv file. I am not sure how to set callback function after file gets downloaded.
$.ajax({
url: '#Url.Action("GetAllCustomer", "Customers")',
type: 'POST',
data: { 'customerIds': strCustomerId },
success: function (result) {
if (result == "Success") {
location.href = '#Url.Action("DownloadFile", "Customers", new { extension = "csv"})';
} else {
toastLast = toastr.error("No data found", "Generating File");
}
}
});
In above code in first call i am getting all the customers. On success callback i am calling DownloadFile method to download csv file. i have requirement to send mail after downloading file but i am not sure how will i know that file is downloaded. Or Can I achieve with some other way.
Please find my DownloadFile method of controller as below.
public ActionResult DownloadFile(string extension)
{
var dateTime = DateTime.Now.ToString("M.dd.yy");
var fileName = dateTime + " Application File." + extension;
var array = TempData["Output"] as byte[];
if (array != null)
{
var file = File(array, System.Net.Mime.MediaTypeNames.Application.Octet, fileName);
return file;
}
else
{
return new EmptyResult();
}
}
Don't use this line
location.href = '#Url.Action("DownloadFile", "Customers", new { extension = "csv"})';
Instead use a ajax request to the Action method
$.ajax({
type: "POST",
url: '#Url.Action("DownloadFile", "Customers")',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(){
//add your sccuess handlings
}
error: function(){
//handle errors
}
});
I'm trying to delete a file with ajax request:
javascript:
function deleteFile(file_path)
{
var r = confirm("Sure?")
if(r == true)
{
$.ajax({
url: 'delete_file.php',
data: {'file' : file_path },
method: 'GET',
success: function (response) {
alert('Deleted!');
},
error: function () {
alert('Not Deleted!');
}
});
}
}
delete_file.php :
unlink($_GET['file']);
It returns true on succes,but the file is not deleted.
Check the response in AJAX, Best is use JSON DATA to check the response:
// Default AJAX request type is GET so no need to define
$.ajax({
url: 'delete_file.php',
data: {'file' : file_path },
dataType: 'json',
success: function (response) {
if( response.status === true ) {
alert('File Deleted!');
}
else alert('Something Went Wrong!');
}
});
Do It like this in PHP:
// First Check if file exists
$response = array('status'=>false);
if( file_exists('FILE_PATH/FILENAME') ) {
unlink('FILE_PATH/FILENAME');
$response['status'] = true;
}
// Send JSON Data to AJAX Request
echo json_encode($response);
Make sure you are giving the complete path with filename to unlink() function
Try this you need to check file, give permission, then delete it
$filename = 'full absolute file path';
if(file_exists($filename)) {
#chmod($filename, 0777);
#unlink($filename);
return true;
}
As there can be two issues either the file path is not correct or the file is not having permission.
With the above code both will be checked.
I am working with codeigniter and jquery. I am using ajax to send some info to a codeigniter function to perform a db operation , in order to update the page. After the operation is complete I am trying to refresh the page. However the refresh works inconsistently and usually I have to reload the page manually. I see no errors in firebug:
var message = $('#send_message').val()
if ((searchIDs).length>0){
alert("searchIDs "+searchIDs );
$.ajax({
type: "POST",
url: "AjaxController/update",
data:{ i : searchIDs, m : message },
dataType: 'json',
success: function(){
alert("OK");
},
complete: function() {
location.href = "pan_controller/my_detail";
}
})
.done(function() { // echo url in "/path/to/file" url
// redirecting here if done
alert("OK");
location.href = "pan_controller/my_detail";
});
} else { alert("nothing checked") }
break;
How can I fix this?
addendum: I tried changing to ;
$.ajax({
type: "POST",
url: "AjaxController/update",
data:{ i : searchIDs, m : message },
dataType: 'json',
.done(function() { // echo url in "/path/to/file" url
// redirecting here if done
alert("REFRESHING..");
location.href = "pan_controller/my_detail";
});
}
})
This is just defaulting to the website homepage. again, no errors in firebug
Add the window object on location.href like this:
window.location.href = "pan_controller/my_detail";
Try to use full path like
$.ajax({a
type: "POST",
url: "YOURBASEPATH/AjaxController/update",
data:{ i : searchIDs, m : message },
dataType: 'json',
.done(function() { // echo url in "/path/to/file" url
// redirecting here if done
alert("REFRESHING..");
location.href = "YOURBASEPATH/pan_controller/my_detail";
});
}
})
BASEPATH should be like this "http://www.example.com"
Try disabling the csrf_enabled (config/config.php) and trying it. If that works, then re-enable the protection and, instead of compiling data yourself, serialize the form; or, at least include the csrf hidden field codeigniter automatically adds. You can also use GET to avoid the CSRF protection, but that's least advisable of of the solutions.
I have one form ,when i click submit button am saving those values and on button click am calling "SaveData() " method.
So when i try to add data and click on submit button and nothing is happening am getting following errors in my browser log.
My onclick function code
function requestReferral() {
var nameperson = $("#namefield").val();
var contact1 = $("#contact").val();
//Till this part working i mean alert is printing .
$.ajax({
url: '/mycontroller/myfunction',
data: 'name='+nameperson+'&contact='+contact1,
type: 'post',
success: function(result){
data = jQuery.parseJSON(result);
if(data.result == "SUCCESS"){
clearMyFormData();
} else {
showMessage();
}
}
});
}
my error is
Failed to load resource: the server responded with a status of 500 (Internal Server Error) with my controller url www.example.com/mycontroller/myfunction
First of all, check if your url is ok, for example, if you are using php with codeigniter your url need to be like this:
url: <?php echo base_url()?>mycontroller/myfunction
and second, when I used ajax, I send data like this
postData = {
name: nameperson,
contact: contact1
}
$.ajax({
url: '/mycontroller/myfunction',
data: postData
type: 'post',
success: function(result){
data = jQuery.parseJSON(result);
if(data.result == "SUCCESS"){
clearMyFormData();
} else {
showMessage();
}
}
I have an ajax request like :
$.ajax({
type: "GET",
url: "services/Test.class.php",
data: "call=getTest",
success: function (data) {
alert(data);
},
error: function (response) {
alert("Error getting php file");
}
});
So, in my class ( Test.class.php ), I have a getTest() function and a require_once('OtherPHP'),
When I test this code, I have an error in require once :
No such file or directory
in my alert(data)
how can I fix it?
It seems like you've included a wrong path of OtherPHP file in Test.class.php. Use file_exists() function to make sure that given path really exists before including/requiring in Test.class.php
if (file_exists(`OtherPHP.php`)) {
require_once(`OtherPHP.php`)
} else {
echo "The file `OtherPHP.php` does not exist";
}
You cant able to call the class directly from ajax,
create new php file say test.php
in test.php
include("Test.class.php");
$test = new Test();
$test ->getTest(); //print the getTest outpout here
Javascript:
$.ajax({
type: "GET",
url: "test.php",
