I want to retrieve parameter passes from ajax in Controller in Codeigniter but did not know how to use it my ajax function is below
function sendVideoData(frm_id)
{
var data = new FormData(document.getElementById("post_video_"+frm_id));
// make the AJAX request
jQuery.ajax({
type: "POST",
url: "<?php echo base_url(); ?>"+"dashboard/do_upload",
data: data+'&form_id='+frm_id,
mimeType:"multipart/form-data",
contentType: false,
cache: false,
processData:false,
dataType: 'json',
success: function (data) {
alert(data);
},
});
return false;
}
</script>
I want to retrieve
form_id
in my controller and use it
It's pretty simple,
echo $this->input->post('form_id')
or simple php
echo $_POST['form_id']
inside your controller dashboard and method do_upload
You can get all list of post variables using print_r($this->input->post()) as well.
Your AJAX request can be:
jQuery.ajax({
type: "POST",
url: "<?php echo base_url() ?>dashboard/do_upload",
data: 'form_id=' + frm_id + '&data=' + data,
mimeType: "multipart/form-data",
contentType: false,
cache: false,
processData:false,
dataType: 'json',
success: function (data) {
alert(data);
},
});
And in ur controller: $this->input->post('form_id');

I want to pass multiple parameters through GET method in URL of ajax call but its not working.any kind help would be appreciated Thankyou

I am noob at using jquery and ajax. I need to change the form from $.post to $.ajax .
var disqus_config = function() {
this.callbacks.onNewComment = [function(comment) {
$.post("sendnotification", { comment: comment.id, post: $post->id,author:$author->id}, function(result){
alert(result);
});
}];
};
I know I need to end something like here but I am stuck how to use post datas(comment,post,author) inside this function
$.ajax({
url: 'sendnotification',
type: 'POST',
data: 'query=' + query ,
dataType: 'JSON',
async: true,
success: function(data){
process(data)
}
Thanks
Just use the same object literal you did for $.post, eg (gotta assume that's some PHP or something in there)
$.ajax({
url: 'sendnotification',
type: 'POST',
data: { comment: comment.id, post: {$post->id}, author: {$author->id} },
dataType: 'json',
async: true,
success: function(data){
process(data)
}
});
I believe dataType: 'JSON' should be changed to dataType: 'json'
Also, use the same data array as you used in your $.post variant.
$.ajax({
url: 'sendnotification',
type: 'POST',
data: { comment: comment.id, post: $post->id,author:$author->id } ,
dataType: 'json',
async: true,
success: function(data){
process(data)
}
});
My jQuery ajax posting is not working. Here is the javascript
function SocialButtons() {
var $buttonWrapper = jQuery('.WrapperDiv');
if ($buttonWrapper.length){
var postData = $buttonWrapper.html();
jQuery.ajax({
type: 'POST',
url: 'http://www.wordpress-site.com/wp-contents/themes/theme-name/post.php',
data: postData,
cache: false,
success: function(data) {
console.log(data);
},
contentType: "application/json",
dataType: 'json'
});
}
}
I am saving the data to be posted inside a hidden div like
<div class='WrapperDiv hidden'>{"post_id":392,"url":"http:\/\/www.wordpress-site\/post\/post-title\/","title":"SEO Friendly title"}</div>
All I am getting in return from the post.php page is an empty array. Here is my code for post.php
<?php
if(isset($_POST)){
print_r($_POST);
} else {
echo "0";
}
?>
Any Idea whats wrong?
EDIT : Its working after I removed
contentType: "application/json",
dataType: 'json'
What about something like this:
var postData = "data=" + encodeURCIComponent($buttonWrapper.html());
Than in PHP:
echo $_POST["data"];
Than parse it or something....
Couple of things to try,
Try to pass the data directly in to the data object first. If it
works then you can debug and see why it's not ready your hidden div.
instead of $buttonWrapper.html try $buttonWrapper.text();
function SocialButtons() {
var $buttonWrapper = jQuery('.WrapperDiv');
if ($buttonWrapper.length){
var postData = $buttonWrapper.**text**();
jQuery.ajax({
type: 'POST',
url: 'http://www.wordpress-site.com/wp-contents/themes/theme-name/post.php',
data: **{'id':1}**,
cache: false,
success: function(data) {
console.log(data);
},
contentType: "application/json",
dataType: 'json'
});
}
}
Inside your jQuery ajax call, your data is not set to $_POST variable names. Hence why nothing is showing
Try changing your function to this:
function SocialButtons() {
var buttonWrapper = jQuery('.WrapperDiv');
if (buttonWrapper.length){
var postData = buttonWrapper.html();
jQuery.ajax({
type: 'POST',
url: 'http://www.wordpress-site.com/wp-contents/themes/theme-name/post.php',
data: {postData: postData},
cache: false,
success: function(data) {
console.log(data);
},
contentType: "application/json",
dataType: 'json'
});
}
}
Then you should have a $_POST['postData'] variable on your print_r or var_dump of $_POST.
Its working after I removed
contentType: "application/json",
dataType: 'json'
I use codeigniter and i want make uniqid code with php as following code(by random_string()):
function coding(){
echo random_string('unique');
}
I want use result top function in a, jquery function (for use in js code), i in jquery code try as this, but this output in alert(coding()) is "undefined". How can fix it?
function coding(){
$.ajax({
type: "POST",
dataType: "text",
url: "coding",
cache: false,
success: function (data) {
return data;
}
})
}
alert(coding()) // in here output is "undefined" !!!?
function coding(){
var temp;
$.ajax({
type: "POST",
dataType: "text",
url: coding,
cache: false,
async: false,
success: function (data) {
temp = data;
}
})
return temp;
}
alert(coding());
You will receive an [object XMLDocument].
It is becuse coding function is asynchronous.
Use follow code:
function coding(){
$.ajax({
type: "POST",
dataType: "text",
url: coding,
cache: false,
success: function (data) {
alert(data);
}
})
}
coding();
function coding(){
$.ajax({
type: "POST",
dataType: "text",
url: "coding",
cache: false,
success: function (data) {
$("#yourDiv").html(data);
}
})
}
You can assign value to another element like div, p etc.
Well, I'm assuming that the coding variable you are passing at the parameter url is a reference to a method in your CI controller.
If that's the case, you just need to wait from the success callback:
$.ajax({
type: "POST",
dataType: "text",
url: coding,
cache: false,
success: function (data) {
alert(data);
}
})
Ok, you should use callback function like this:
function coding(func){
$.ajax({
type: "POST",
dataType: "text",
url: coding,
cache: false,
success: function (data) {
func(data);
}
})
}
coding(function(data)
{
alert(data);
});
All,
I want to send a variable "itemId" via GET to a controller action through AJAX. In the Controller Action, I should be able to retrieve the value using $_GET["itemId"];
Can I send the querystring with "data" tag instead of appending it to the "url"?
I have the following code:
$.ajax({
type: 'GET',
url: "/controller/controlleraction",
data: itemId,
cache: false,
dataType: "html",
success: function(html_input)
{
alert(html_input);
}
});
How can I do this?
data: {itemId: itemId},
$.ajax({
type: 'GET',
url: "/controller/controlleraction",
data: ({itemId: itemId}),<------change it to this
cache: false,
dataType: "html",
success: function(html_input)
{
alert(html_input);
}
});
Make itemId a JavaScript object before making the AJAX request. For example:
var itemId = {'itemId': 1000};
data: {itemId: "you info"},
or
data: "itemId=you info",
