I've been googling for a way to do this but everything I have found doesn't help me.
I'm not sure how to post all the below variables, If I select only one of them it'll post just fine as well as putting it into the correct database column.
any help would be much appreciated.
function submit() {
var mm10 = $('#10MM'),
mm16 = $('#16MM'),
mm7 = $('#7MM'),
mm2 = $('#2MM'),
fines = $('#Fines'),
bark = $('#Bark'),
cqi = $('#CQI');
$.ajax({
type: "POST",
url: "classes/Post/ChipSubmit.php",
data: ,
success: function(){
$("#successMessage").show();
}
});
};
You can do it in two ways. One using arrays, or two using objects:
function submit() {
var mm10 = $('#10MM').val(),
mm16 = $('#16MM').val(),
mm7 = $('#7MM').val(),
mm2 = $('#2MM').val(),
fines = $('#Fines').val(),
bark = $('#Bark').val(),
cqi = $('#CQI').val();
$.ajax({
type: "POST",
url: "classes/Post/ChipSubmit.php",
data: [mm10, mm16, mm7, mm2, fines, bark, cqi],
success: function() {
$("#successMessage").show();
}
});
} // Also you don't need a semicolon here.
Also you don't need a semicolon at the end of the function.
Using arrays is easier, if you want more precision, use objects:
function submit() {
var mm10 = $('#10MM').val(),
mm16 = $('#16MM').val(),
mm7 = $('#7MM').val(),
mm2 = $('#2MM').val(),
fines = $('#Fines').val(),
bark = $('#Bark').val(),
cqi = $('#CQI').val();
$.ajax({
type: "POST",
url: "classes/Post/ChipSubmit.php",
data: {
"mm10": mm10,
"mm16": mm16,
"mm7": mm7,
"mm2": mm2,
"fines": fines,
"bark": bark,
"cqi": cqi
},
success: function() {
$("#successMessage").show();
}
});
} // Also you don't need a semicolon here.
And in the server side, you can get them through the $_POST super-global. Use var_dump($_POST) to find out what has it got.
Kind of like Praveen Kumar suggested, you can create an object. One thing I was curious about, it looks like you're passing jQuery objects as your data? If that's the case, $_POST is going to say something like [object][Object] or, for me it throws TypeError and breaks everything.
var form_data = {};
form_data.mm10 = $('#10MM').val(); // Input from a form
form_data.mm16 = $('#16MM').val(); // Input from a form
form_data.mm7 = $('#7MM').val(); // Input from a form
form_data.mm2 = $('#2MM').text(); // Text from a div
form_data.fines = $('#Fines').text();
form_data.bark = $('#Bark').text();
form_data.cqi = $('#CQI').text();
$.ajax({
type: "POST",
url: "classes/Post/ChipSubmit.php",
data: form_data,
success: function() {
alert('success');
}
});
}
Then to get those values in your PHP you'd use:
$_POST[mm10] // This contains '10MM' or the value from that input field
$_POST[mm16] // This contains '16MM' or the value from that input field
$_POST[mm7] // This contains '7MM' or the value from that input field
$_POST[mm2] // This contains '2MM' or the value from that input field
And so on...
I tried to put together a jsFiddle for you, though it doesn't show the PHP portion. After you click submit view the console to see the data posted.

I have used ajax as below:
$('.province').on('click', function (e)
{
var optionSelected = $("option:selected", this);
var valueSelected = this.value;
var valueSelected = valueSelected.replace(/ /gi,"%20");
var valueSelected = encodeURIComponent(valueSelected);
//alert(valueSelected);
$.ajax({
type: 'post',
encoding:"UTF-8",
url: "<?php echo base_url();?>Search/cities_of_province/"+valueSelected,
data: '',
contentType: "charset=utf-8",
success: function (result) {
//alert(result);
$('.city').html(result);
return false;
}
});
return false;
});
valueSelected in above url is a persion statement with space in it. for example it is استان آذربایجان شرقی.
when it is post to the url, just first part(استان) is recieved.
I aslo removed valueSelected.replace(/ /gi,"%20") and encodeURIComponent(valueSelected) but nothing happend.
what is the solution?
I faced no issue like that.. I used no encodeURIComponent no encoding:"UTF-8" no contentType: "charset=utf-8"
Nothing needed. And it works simply perfect. I tested it with following code
I have Html
<input id='yourInputId' value='استان آذربایجان شرقی' />
JavaScript
<script>
var valueSelected = $('#yourInputId').val();
//before ajax request
alert(valueSelected ); // it gives me here =>استان آذربایجان شرقی
//before making ajax reuest plz confirm you get above value correctly here
alert(<?php echo base_url();?>); //it must be valid as well
$.ajax
({
type: "POST",
url: "<?php echo base_url();?>Search/cities_of_province", //should be valid
data: { province : valueSelected },
success: function (result) {
alert(result); //it gives => استان آذربایجان شرقی
},
error:function(a)
{
alert(a.responseText);
}
});
</script>
PHP
<?php
if(isset($_POST['province']))
$v = $_POST['province'];
else
$v = 'Province value not provided from client side';
echo $v;
?>
So it looks like you are using a select input here. If that is the case, you should use alphanumeric/ASCII value key in your options and not the human readable labels. That might look like:
<option value="some_ascii_key">استان آذربایجان شرقی</option>
You can then have a reliable key to use in your AJAX request.
I also think your request should be a GET and not a POST since you are just reading values from API rather than trying to create/update records via API.
Putting it all together, you might have something like this:
// note values for each property/ley may not be important here
// as they are not really needed to validate that the province key
// in option value has not been modified by client,
// which is really what you are using this for.
// If you need to have option label text available in
// javascript you can store that here as shown.
var provinceConfiguration = {
'key1': 'استان آذربایجان شرق';
'key2': 'some other Persian string';
// and so on...
}
$('.province').on('click', function (e)
{
var optionSelected = $("option:selected", this);
var valueSelected = this.value;
// perhaps validate that value provided is amongst expected keys
// this used the provinceConfiguration object proposed in this example
if(typeof provinceConfiguration[valueSelected] === 'undefined') {
console.log('Unexpected province key passed');
e.stopPropagation();
return false;
}
// probably can drop this line if defined keys do not need encoding
var valueSelected = encodeURIComponent(valueSelected);
// since you can use default GET setting you can use this shorthand
$.get(
'<?php echo base_url();>Search/cities_of_province/' +
valueSelected,
function(result) {
// console.log(result);
$('.city').html(result);
return false;
}
);
/*
Or more verbose option
$.ajax({
type: 'GET',
// not valid setting key -> encoding:"UTF-8",
url: '<?php echo base_url();>Search/cities_of_province/' + valueSelected,
// default is fine here so not needed -> contentType: "charset=utf-8",
success: function (result) {
// console.log(result);
$('.city').html(result);
return false;
}
});
*/
return false;
});
Note that you should be using console.log() to debug code rather than alert(), as alert actually blocks code execution and may make some debugging more problematic as your debugging mechanism changes how your code executes. This can problem can be exacerbated when debugging asynchronous code.
Your server-side code would obviously need to be updated to understand the province keys as well.
Please take a look at this javascript library. That can be of help to you.

I have a form which I would like to submit via Ajax, however, part of it contains an array. I am having difficulty passing this array via Ajax. An example of my Ajax is below, where I would usually pass the form entry data via how it is below after data (one: $('#one').val()) where I would have one row of this for each field.
Now I have a new set of fields, where the information needs to be passed through as an array. I have tried using serialize and formData -- var fd = new FormData("#form") -- and so far either just this array has been passed through, or nothing from the form is passed through, or just the array is not passed through.
Can anyone please point me in the right direction?
$("#form").submit(
function() {
if (confirm('Are you sure you want to edit this?')) {
$("#formMessages").removeClass().addClass('alert alert-info').html(
'<img src="images/loading.gif" /> Validating....').fadeIn(500);
$.ajax({
url: $("#form").attr('action'),
dataType: 'json',
type: 'POST',
data: {
one: $('#one').val(),
two: $('#two').val()
},
success: function(data){
//success stuff would be here
}
});
}
return false;
});
Thanks.
You could try using :
var dataSend = {};
dataSend['one'] = $('#one').val();
dataSend['two'] = $('#two').val();
dataSend['three'] = $('#three').val();
then in the ajax
data: {dataSend:dataSend}
You can gather data in php with json:
$json = json_encode($_POST['dataSend']);
$json = json_decode($json);
print_r($json);
To see output.
Edit:
You can gather data in php like below:
$one = $json->{'one'};
$two = $json->{'two'};
Have you tried this:
Written in JavaScript:
your_array = JSON.stringify(your_array);
And in PHP:
$array = json_encode($_POST['array']);
I am continuing a previous question that was asked onclick -> mysql query -> javascript; same page
This is my onchange function for a drop down of names. it is called when each drop down is changed. The idea is to send each runners name into the php page to run a mysql query then return 3 arrays to be entered into javascript.
function sendCharts() {
var awayTeam = document.getElementById('awayRunner').value;
var homeTeam = document.getElementById('homeRunner').value;
if(window.XMLHttpRequest) {
xmlhttp14 = new XMLHttpRequest();
}
else {
xmlhttp14 = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp14.onreadystatechange = function() {
if(xmlhttp14.readyState == 4 && xmlhttp14.status == 200) {
var parts = xmlhttp14.responseText.split(','); //THIS IS WHAT IS RETURNED FROM THE MYSQL QUERY. WHEN I ALERT IT, IT OUTPUTS IN THE FORM 14,15,18,16,17,12,13
... code that generates the chart
series: [ {
name: document.getElementById('awayRunner').value,
data: [parts,','], //THIS IS WHERE AN ARRAY MUST BE ENTERED. THIS OUPUTS ONLY ONE NUMBER
type: 'column',
pointStart: 0
//pointInterval
},
{
name: document.getElementById('homeRunner').value,
data: parts, // TRIED THIS
type: 'column',
pointStart: 0
//pointInterval
},
{
name: 'League Avg',
data: [], //THIS IS WHERE 3rd ARRAY MUST BE ENTERED
type:'spline',
pointStart: 0
//pointInterval
},
]
});
}
}
xmlhttp14.open("GET", "getCharts.php?awayRunner="+awayRunner+"&homeRunner="+homeRunner, true);
xmlhttp14.send();
}
my php code looks like this. As you'll see, there are 3 arrays that must be returned to be entered into different spots in the javascript to generate the code.
$away=$_GET['awayRunner'];
$home=$_GET['homeRunner'];
$db=mydb;
$homeRunner=array();
$awayRunner = array();
$totalOverall= array();
$getHome="select column from $db where tmName = '$home'";
$result2 = mysql_query($getHome);
while($row = mysql_fetch_array($result2)){
$homeRunner[]= $row['column'];
}
$getAway="select column from $db where tmName ='$away'";
$result22 = mysql_query($getAway);
while($row2 = mysql_fetch_array($result22)){
$awayRunner[]= $row2['column'];
}
$week = 0;
while($week<20){
$week++;
$teamCount = "select count(column) from $db where week = $week";
$resultTeam = mysql_query($teamCount);
$rowTeam = mysql_fetch_array($resultTeam);
$t = $rowTeam['count(column)'];
$getLeague = "select sum(column) from $db where week = $week";
$resultLeague = mysql_query($getLeague);
while($row3 = mysql_fetch_array($resultLeague)){
$totalOverall[]=$row3['sum(column)']/$t;
}
}
echo join(',',$awayRunner);
currently, by doing it this way, the chart only outputs the second value in the array. for instance, if var parts is equal to 23,25,26,24,23...only 25 is shown.
A previous question resulted with the following answer -
Load the page.
User chooses an option.
An onChange listener fires off an AJAX request
The server receives and processes the request
The server sends back a JSON array of options for the dependent select
The client side AJAX sender gets the response back
The client updates the select to have the values from the JSON array.
I'm lost on #'s 5 - 7. Can someone provide examples of code that gets this done? Normally, I would just ask for direction, but I have been stuck on this problem for days. I'm about ready to scrap the idea of having charts on my site. Thanks in advance
EDIT
this is the first change that I have made to send and receive just one request
<script>
$(function(){
$("#awayRunner").change(function(){
$.ajax({
type: "POST",
data: "data=" + $("#awayRunner").val(),
dataType: "json",
url: "/my.php",
success: function(response){
alert(response);
}
});
});
});
The data displayed in the alertbox is in the form 12,15,16,15. Now, when I enter in
data: response,
only the second number from each is being displayed in the chart. Any ideas?
EDIT
OK, so i figured out that the info in response is a string. It must be converted to an INT using parseInt to be usable in the chart. currently, I have
$("#awayTeam").change(function(){
$.ajax({
type: "POST",
data: "away=" + $("#awayTeam").val(),
dataType: "json",
url: "/getCharts.php",
success: function(response){
var asdf = [];
asdf[0] = parseInt(response[0]);
asdf[1] = parseInt(response[1]);
asdf[2] = parseInt(response[2]);
asdf[3] = parseInt(response[3]);
alert(asdf);
will have to write a function to make this cleaner.
I can't believe it, but I finally got it. here is how I used an onchange method to stimulate a MYSQL query and have the Highchart display the result. The major problem was that the returned JSON array was a string that needed to be converted into an INT. The resultArray variable is then used in the data: portion of the highChart.
$(function(){
$("#awayTeam").change(function(){
$.ajax({
type: "POST",
data: "away=" + $("#awayRunner").val(),
dataType: "json",
url: "/getCharts.php",
success: function(response){
var arrayLength = response.length;
var resultArray = [];
var i = 0;
while(i<arrayLength){
resultArray[i] = parseInt(response[i]);
i++;
}
In the PHP code, the array must be returned as JSON like this
echo json_encode($awayRunner);
I am having some problems with insert query which is called from ajax. The ajax call comes back with success and I am able to see it with the changed html as noted below in the code under success:function(). I am not sure why the insert query in process.php is not working. dataString has the arguments correct (alert for dataString shows the right arguments) and my fields in database can take null values.
js code
var dataString=$('#testimonials').serialize();
alert (dataString);
$.ajax(
{
type: "POST",
url: "process.php",
data: dataString,
success:function() {
$('#testimonials').html("<div id='message'></div>");
$('#message').html("<h2>Your information has been submitted!</h2>")
.append("<p>Thank you for your help and support.</p>")
.hide()
.fadeIn(1500, function()
{
$('#message').append("<img id='checkmark' src='images/check.png' height='30' width='30'/>");
});
});
process.php file
$company =mysql_escape_string($_POST('company'));
$jobfunc = mysql_escape_string($_POST('jobfunc'));
$location = mysql_escape_string($_POST('location'));
$overall = mysql_escape_string($_POST('overall'));
$detail = mysql_escape_string($_POST('detail'));
$pros = mysql_escape_string($_POST('pros'));
$cons = mysql_escape_string($_POST('cons'));
$sr_mgmt = mysql_escape_string($_POST('sr_mgmt'));
$submitted_by = mysql_escape_string($_POST('submitted_by'));
$class = mysql_escape_string($_POST('classof'));
$school = mysql_escape_string($_POST('school'));
$anonymous = mysql_escape_string($_POST('anonymous'));
mysql_select_db($database_connTest, $connTest);
$query_AddTestimonial = "INSERT into testimonials (company,job_function,location,overall,project_details,pros,cons,sr_mgmt,submitted_by,class,school,anonymous) VALUES ('$company','$jobfunc','$location','$overall','$detail','$pros','$cons','$sr_mgmt','$submitted_by','$class','$school','$anonymous')";
$result_AddTestimonial = mysql_query($query_AddTestimonial) or die(mysql_error());
In the penultimate line when you create $query_AddTestimonial, the string you're creating isn't putting the php variables in because you're not telling it that they're variables. You can use the php variables like this:
$query_AddTestimonial = "INSERT into testimonials (company,job_function,location,overall,project_details,pros,cons,sr_mgmt,submitted_by,class,school,anonymous) VALUES ('{$company}','{$jobfunc}','{$location}','{$overall}','{$detail}','{$pros}','{$cons}','{$sr_mgmt}','{$submitted_by}','{$class}','{$school}','{$anonymous}')";
The problem was with the way I was calling the variables. It should have been $_POST['company'] rather than $_POST('company'). Completely missed it (the square brackets for $_POST since its an array)
I was chasing after JSON as a method to do this, but I'm wondering if I should have been looking in a different direction. I'll tackle this as simply as possible.
Jquery from "page1.php"
$(".button").click(function() {
var name = "Jeremy";
var car = "Saturn";
var color = "blue";
var state = "Mississippi";
// I need all four of these to get passed over to PHP in the following ajax
$.ajax({
url: "page2.php",
//dataType: '???????',
type: 'POST',
data: 'mydata=' + ????????,
success: function(result) {
alert(result);
}
});
});
So there are four jquery variables that I've fudged. Now I need to hand them over to page2.php for my backend PHP. Here is page2.php
if (filter_has_var(INPUT_POST, "mydata")) {
$mydata = mysql_real_escape_string(filter_input(INPUT_POST,'mydata'));
// Here I need to turn these into variables, or just an array and then throw them into my SQL
mysql_query("INSERT INTO mysqldata (namefield, carfield, colorfield, statefield)
VALUES ($name, $car, $color, $state)");
$sqlresult = mysql_insert_id;
if ($sqlresult != '') {
echo "SQL successfully updated.";
}
}
Thus, my question is: What is the most effective method to pass the data to PHP, in this case?
There's probably a simple answer here that I just don't know. Can I turn those jquery variables into an array and hand them to PHP that way? Is JSON still the best way to go, and I just need to know how to convert it on the back end?
As an array
var mydata = [name, car, color, state];
Or as an object
var mydata = { 'name' : name, 'car' : car, 'color' : color, 'state' : state };
-
$.ajax({
...
data: mydata
...
JavaScript/jQuery
$(".button").click(function() {
// create the data object
var myData = {
name : 'Jeremy',
car : 'Saturn',
color: 'blue',
state: 'Mississippi'
};
$.ajax({
url: "page2.php",
//dataType: '???????',
type: 'POST',
data: myData,
success: function(result) {
alert(result);
}
});
});
PHP
// check if the name has been posted, which means we have a submission to process
if(isset($_POST['name'])){
$query = sprintf("INSERT INTO mysqldata (namefield, carfield, colorfield, statefield) VALUES ('%s', '%s', '%s', '%s')",
mysql_real_escape_string($_POST['name']), // clean malicious code
mysql_real_escape_string($_POST['car']), // from user input
mysql_real_escape_string($_POST['color']), // to protect against
mysql_real_escape_string($_POST['state'])); // SQL injection
// run the query
$result = mysql_query($query);
// check if the insert was done successfully
if($result){
echo 'SQL successfully updated.';
}
}
If you notice, based on the id we used on the javascript object to assign the data, we are accessing it in the $_POST array. E.g.
The name
var myData = {
name : 'Jeremy',
...
}
Will be access on PHP side with
$_POST['name']
