jQuery ajax, send data - php

i'm having a problem sending the option selected with ajax.
Code:
$("#editarConta").on('submit',(function(e) {
e.preventDefault();
$.ajax({
url: "includes/php/class_conta.php",
type: "POST",
data: new FormData(this),
contentType: false,
cache: false,
processData:false,
success: function(resultado){
$("#accountEdit_result").html(resultado);
}
});
}));
Sending this data i can't see what option was selected. Is any way i can send this data, plus the selected option like:
data: { new FormData(this) , optionSelected: $( "#linguagem_favorita option:selected" ).val() },
My select HTML code:
<select name="linguagem_favorita" id="linguagem_favorita" class="form-control">
If i send with my code i get NULL when i var_dump the variable
var_dump($_POST["linguagem_favorita"]);

Append to the form data:
$("#editarConta").on('submit',(function(e) {
e.preventDefault();
var formData = new FormData(this);
formData.append("optionSelected", $("#linguagem_favorita option:selected" ).val() );
$.ajax({
url: "includes/php/class_conta.php",
type: "POST",
data: formData,
contentType: false,
cache: false,
processData:false,
success: function(resultado){
$("#accountEdit_result").html(resultado);
}
});
}));

Why ajax couldn't reload new post?

This is the code I use. The problem is new data doesn't appear, unless I reload it.
$(document).ready(function(){
// temp
$.ajax({

type: 'POST',
async: false,
success: function(show_chat) {
$('#direct-chat').html(show_chat);
},

});
// temp
$("#text-on-it").submit(function(event){ // when send message
event.preventDefault();
var formData = new FormData(this);
$.ajax({
url: 'assets/php/act_now/module_loadChat.php',
type: 'POST',
data: formData,
async: false,
success: function(data) {
$('#direct-chat').html(data);
$("#text-on-it")[0].reset();

});
setInterval(function(){
// this will run after every 5 seconds
}, 5000);

JQuery fomdata sending empty data to php file?

I am trying to upload file through jquery formdata without any form. My problem is that it is not sending any data to php file.
Here is my jquery code
jQuery(document).ready(function() {
jQuery('#e_picture').change(function() {
var file_data = jQuery('#e_picture').prop('files')[0];
var form_data = new FormData();
form_data.append('e_picture', file_data);
form_data.append('e_uid', '3585');
//});
// data: {e_uid: e_uid, e_picture:'23'},
jQuery.ajax({
url: "index.php?option=com_objectified&task=course_reg.addPicture",
type: 'POST',
data: {
form_data
},
processData: false,
contentType: false,
success: function(result) {
alert('This is ' + result); // Here I show onlu e_uid but it alerts blank result
}
});
});
});
Html
<input type="file" class="form-control" name='e_picture' id='e_picture'>
You are sending the form_data in wrong way
instead of
data: {
form_data
},
just send it like
data: form_data,
jQuery(document).ready(function() {
jQuery('#e_picture').change(function() {
var file_data = jQuery('#e_picture')[0].files;
var form_data = new FormData();
form_data.append("e_picture[]", file_data[0]);
form_data.append('e_uid', '3585');
//});
// data: {e_uid: e_uid, e_picture:'23'},
jQuery.ajax({
url: "index.php?option=com_objectified&task=course_reg.addPicture",
type: 'POST',
data: {
form_data
},
processData: false,
contentType: false,
success: function(result) {
alert('This is ' + result); // Here I show onlu e_uid but it alerts blank result
}
});
});
});
ange content type to :
contentType: 'multipart/form-data',

Uploading image and data using ajax and php

I am trying to upload firstname, lastname, description and image path to MySql database. And move uploaded image to specific folder.
Here is my ajax function
formData = new FormData(addPeopleForm);
var file_data = $('input[type="file"]')[0].file;
formData.append("file", file_data);
$.ajax({
type: "POST",
url: "functions.php",
contentType: false,
cache: false,
processData: false,
data: {
function: "savepeople",
data: formData
}, success: function(data){
console.log(data);
getPeople();
}
});
functions.php
if(isset($_POST['function'])){
$f = $_POST['function'];
if($f == "savepeople"){
require_once("config.php");
echo $_POST['firstname'];
.
.
.
you can not send directly image to php file with ajax call, you have to take form enctype="multipart/form-data" while form defination
and replace this code for file upload while ajax call
for appending file in formdata use below code
formData = new FormData(); //your form name
var file_data = $('input[type="file"]')[0].file;
formData.append("file", file_data);
formData.append("function","savepeople"); // new variable for your php condition
$.ajax({
url: "YOUR_FILE_PATH",
type: "POST",
data: formData,
contentType: false,
cache: false,
processData: false,
success: function(data) {
// success operation here
},
and on php side you have to use $_FILES['YOUR_FILE_NAME'] instead of $_POST['YOUR_FILE_NAME'] for accessing a uploaded file on server.
you can try this code
$.ajax({
type:'POST',
url:'functions.php',
data:new FormData($('#my_form')[0]),
cache: false,
contentType: false,
processData: false,
success:function(msg)
{
console.log(msg);
}
});
return false;
where #my_form is your form id
var formData = new FormData($(this)[0]);
var action = "savepeople";
$.ajax({
url : 'functions.php',
type : 'POST',
data: {action:action,formData:formData},
contentType: false,
cache: false,
processData:false,
async : false,
, success: function(data){
console.log(data);
getPeople();
}
});
functions.php
if(isset($_POST['action']) && $_POST['action'] == "savepeople"){
//TO DO CODE
}

AJAX send data to PHP file

send $username php with data: new FormData(this), to add.php like data: new FormData(this),$username how can i do it with ajax code
<script type="text/javascript">
$(document).ready(function (e) {
$("#uploadFormuserimg").on('submit',(function(e) {
e.preventDefault();
$.ajax({
url: "add.php",
type: "POST",
data: new FormData(this),
contentType: false,
cache: false,
processData:false,
success: function(data)
{
$("#user_img_a").html(data);
},
error: function()
{ alert("error");
}
});
}));
});
</script>
var myData = new FormData(this);
myData.append('username','<?php echo $username; ?>');
and get on "add.php" like this
$username = $_POST['username'];
This worked on my side.
Based on comments to the question, specifically:
I just want to add some data
Are you just asking how to add more fields to the object that was created already in the data value? Something like this:
var myData = new FormData(this);
myData.append("anotherField", "anotherValue");
// etc.
Then just use that variable as your AJAX data:
$.ajax({
url: "add.php",
type: "POST",
data: myData,
contentType: false,
cache: false,
processData:false,
success: function(data)
{
$("#user_img_a").html(data);
},
error: function()
{ alert("error");
}
});
You can store anything you like in a variable and use that variable at a later time. With a FormData object you would generally use .append() to add more key/value pairs to it.

jquery change event to submit form using ajax

Here is my form
<form name="uploadImg" id="uploadImg" class="profile-image" enctype="multipart/form-data">
<input type="file" name="profile" id="updProfileImg">
</form>
Here is my jquery event
$("#updProfileImg:file").change(function() {
$('#uploadImg').submit(function() {
var queryString = new FormData($('form')[0]);
$.ajax({
type: "POST",
url: 'index.php?route=account/edit/upload',
data: queryString,
contentType: false,
processData: false,
beforeSend: function() {
},
success: function() {
}
})
})
})
But the change event is not triggering form submit so I tried trigger('submit') but the page is refreshing instead of submitting in ajax.
You are binding the events incorrectly. As you currently have it, changing the field will trigger the binding of the submit. It need to be like this:
// bind the submit event
$('#uploadImg').submit(function() {
var queryString = new FormData($('form')[0]);
$.ajax({
type: "POST",
url: 'index.php?route=account/edit/upload',
data: queryString,
contentType: false,
processData: false,
beforeSend: function() {
},
success: function() {
}
});
});
// bind the change event to trigger a submit
$("#updProfileImg:file").change(function() {
$("#uploadImg").submit();
});
A simple modification works
$("#updProfileImg:file").change(function() {
//$('#uploadImg').submit(function() {
var queryString = new FormData($('#uploadImg')[0]);
$.ajax({
type: "POST",
url: 'index.php?route=account/edit/upload',
data: queryString,
contentType: false,
processData: false,
beforeSend: function() {
},
success: function() {
}
})
//})
})
you should try this code:
$("#updProfileImg:file").on("change", function(){
var queryString = new FormData($('#uploadImg')[0]);
$.ajax({
type: "POST",
url: 'index.php?route=account/edit/upload',
data: queryString,
contentType: false,
processData: false,
beforeSend: function() {},
success: function() {}
})
});
because i expect the ".change()" will be fired one time in the first change.
