I am trying to get the excelPrintarea and post that data to my Employees controller. But when I add the data and datatype attribute it tells me it's an illegal invocation. I don't understand why it is saying that.
Also when I leave the data, datetype and POST out the downloadExcel from my employees controller does fire.
function printExcel() {
var excelPrintarea = document.getElementById('printarea');
$.ajax({
url: "<?php echo $this->webroot; ?>employees/downloadExcel",
data: {myPrintArea: excelPrintarea},
dateType: 'json',
type: 'POST',
cache: false,
success: function(excelPrintarea) {
alert("printing excel worked")
}
});
}

if(autoMode){
$.ajax({
type:'POST',
url: 'msgHandle.php',
data: formdata,
contentType: false,
cache: false,
processData: false,
beforeSend: function() {
},
success: function(data) {
alert(data);
},
error: function() {
alert('failed');
}
});
I have set a button to click and when clicked in runs this ajax code. the output is a alert with empty message. that means it success but seems like variables does not pass correctly to the php code. what is wrong in my code, I can't find.
I tried your code and found that by removing all the three parameters
contentType: false,
cache: false,
processData: false,
From the code posts your data onto another page.
Tried for just a sample array.
Please how can I send a whole number like twelve to php using ajax. I have been able to send string variables using both GET and POST methods successfully, but when it comes to numerical values it becomes a problem , I don't know why.below is my jQuery
function user_ajax_call(){
var data = $(".people_names").length;
var more_loader = $("<img id='hiddenL' src='../ForePost/icons/spin.gif'/>");
$("#pple").append(more_loader);
$.ajax({
url: 'http://localhost/Forepost/mod/loadmore_data.php',
dataType: 'text',
type: 'POST',
data:{data:data},
processData: false,
contentType: false,
cache:false,
success: function(returndata){
$("#pple").append(returndata);
more_loader.hide();
},
error: function () {
}
});
}
And these are sample php lines
$limistart = $_POST['data'];
if(isset($limistart)){
echo $limistart;
}
You need to send them through: data.
You could do something like this in your data variable:
data = {
name_length : $(".people_names").length,
number : 12
};
And just pass it like this in your ajax:
function user_ajax_call(){
var data = {
name_length : $(".people_names").length,
number : 12
};
var more_loader = $("<img id='hiddenL' src='../ForePost/icons/spin.gif'/>");
$("#pple").append(more_loader);
$.ajax({
url: 'http://localhost/Forepost/mod/loadmore_data.php',
dataType: 'text',
type: 'POST',
data: data,
success: function(returndata){
$("#pple").append(returndata);
more_loader.hide();
},
error: function () {
}
});
}
And in your server side access it like :
$_POST['name_length']
$_POST['number']
If you change the value of contentType key it should work correctly.
So change this:
contentType: false
to:
contentType: "application/x-www-form-urlencoded; charset=UTF-8"
EDIT:
and change the line:
processData: false
to:
processData: true
I have a variable which contains data, i'm then using a ajax function to send this variable data to this php file. I'm slightly unsure I can store this variable into php and echo it out. This is the code that I currently have...
var data = 1
// Sending this data via ajax to php file/
$.ajax({
type: 'post',
cache: false ,
url: 'function.php',
data: data,
success: function(data) {
alert ( data );
}
});
This is my php code
$noteone = $_POST['data'];
echo $noteone;
Any help would greatly be appreciated
data of your ajax call should be like below. Hope it will solve your problem.
data: { "data": data }
You also need to set the data type:
var data = 1
// Sending this data via ajax to php file/
$.ajax({
type: 'post',
cache: false ,
url: 'function.php',
data: { "data": data },
dataType: "json", // <---- THIS ONE
success: function(data) {
alert ( data );
}
});
Try this :
var data = 1
// Sending this data via ajax to php file/
$.ajax({
type: 'post',
cache: false ,
url: 'function.php',
data: JSON.stringify(data),
contentType: "application/json",
success: function(data) {
alert ( data );
}
});
PHP requires data to be submitted in key=value format when building $_POST/$_GET. You didn't do that. You only submitted value, so PHP has no key to populate $_POST with. You need to have:
data: { "whatever_you_want": data }
which becomes
$_POST['whatever_you_want']
How to pass the fetched data using $.get() from a URL to a particular URL with query_string that can be retrieved using $_GET() in PHP. I'm using following but not working. I want to pass the fetched data into following parameter http://example.com/data?data=FETECHED_DATA
<?php
$ip_address=$_SERVER['REMOTE_ADDR'];
echo '<script>
$.get( "http://ipinfo.io/'.$ip_address.'/org", function( data ) {
$.ajax({
type: "GET",
url: "http://example.com/data",
data: data,
success: success,
dataType: dataType
});
});
</script>';?>
Well, don't recommended PHP to fetch and send data
I believe this will do what you want
<?php
$ip_address=$_SERVER['REMOTE_ADDR'];
echo '<script>
$.get("http://ipinfo.io/'.$ip_address.'/org", function(data) {
$.ajax({
type: "GET",
url: "http://example.com/data",
data: {data : data},
success: success,
dataType: dataType
});
});
</script>';?>
the only change is data: data changed to data: {data: data}
that's a lot of data :p
see this cut down mock up, http://jsfiddle.net/cm8o5dk8/ if you have a decent browser that can show you the network "usage" you'll see that the mockup fails trying to GET http://example.com/data?data=AS15169+Google+Inc.%0A - the %0A comes back from ipinfo.io
Thanks it worked
$.get("http://ipinfo.io/8.8.8.8/org", function(data) {
$.ajax({
type: "GET",
url: "http://example.com/data",
data: {data : data},
success: function() {},
dataType: 'json'
});
});
Im submitting Data to a php file via AJAX using POST.
It worked fine with just submitting strings, but now I wanted to submit my JS Object with JSON and decode it on PHP side.
In the console I can see, that my data is submitted correctly but on PHP side json_decode returns NULL.
I've tried the following:
this.getAbsence = function()
{
alert(JSON.stringify(this));
jQuery.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "ajax/selectSingle.php?m=getAbsence",
data: JSON.stringify(this),
success : function(data){
alert(data);
}
});
}
PHP:
echo $_POST['data'];
echo json_decode($_POST['data']);
echo var_dump(json_decode($_POST['data']));
And:
this.getAbsence = function()
{
alert(JSON.stringify(this));
jQuery.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "ajax/selectSingle.php?m=getAbsence",
data: {'Absence' : JSON.stringify(this)},
success : function(data){
alert(data);
}
});
}
PHP:
echo $_POST['Absence'];
echo json_decode($_POST['Absence']);
echo var_dump(json_decode($_POST['Absence']));
The alert was just to check everything is alright...
And yea usual string were echoed correctly :-)
Where you went wrong in your code in the first code is that you must have used this:
var_dump(json_decode(file_get_contents("php://input"))); //and not $_POST['data']
Quoting from PHP Manual
php://input is a read-only stream that allows you to read raw data from the request body.
Since in your case, you are submitting a JSON in the body, you have to read it from this stream. Usual method of $_POST['field_name'] wont work, because the post body is not in an URLencoded format.
In the second part, you must have used this:
contentType: "application/json; charset=utf-8",
url: "ajax/selectSingle.php?m=getAbsence",
data: JSON.stringify({'Absence' : JSON.stringify(this)}),
UPDATE:
When request has a content type application/json, PHP wont parse the request and give you the JSON object in $_POST, you must parse it yourself from the raw HTTP body. The JSON string is retrieved using file_get_contents("php://input");.
If you must get that using $_POSTyou would make it:
data: {"data":JSON.stringify({'Absence' : JSON.stringify(this)})},
And then in PHP do:
$json = json_decode($_POST['data']);
Single quotes are not valid for php's json_encode, use the double quotes for both field names and values.
To me, it looks like you should reformat your AJAX object. The url-property should only be the URL for the target php-file and any data that needs to be posted should be in the form of a query-string in the data-property.
The following should work as you expected:
this.getAbsence = function() {
var strJSONData = JSON.stringify(this);
alert(strJSONData);
jQuery.ajax({
type: 'POST',
contentType: 'application/json; charset=utf-8',
url: 'ajax/selectSingle.php',
data: 'm=getAbsence&Absence=' + strJSONData,
success: function(data) {
alert(data);
}
});
}
try this
var vThis = this;
this.getAbsence = function()
{
alert(JSON.stringify(vThis));
jQuery.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "ajax/selectSingle.php?m=getAbsence",
data: JSON.stringify(vThis),
success : function(data){
alert(data);
}
});
}
EDIT
I think we can also do this!
var vThis = this;
this.getAbsence = function()
{
alert(JSON.stringify(vThis));
jQuery.ajax({
type: "POST",
dataType: "json",
url: "ajax/selectSingle.php?m=getAbsence",
data: vThis,
success : function(data){
alert(data);
}
});
}
and in PHP
print_r($_POST);
On PHP side try this:
$sectionValue = htmlspecialchars($_POST['sectionValue'], ENT_QUOTES);
$dataToWrite = json_decode(html_entity_decode($sectionValue, ENT_QUOTES, "utf-8" ), true);
