I wanted to get the form value that have been serialized and send it via AJAX call
var searchData = $("#SearchForm").serialize();
$.ajax({
type: "POST",
url: "search.php",
data: {
thedata : searchData,
page : "listPage="+pageNumber
},
success: function(searchResult){
$("#search-section").ajaxComplete(function() {
$(this).html(searchResult);
});
}
});
What should I do if I wanted to access data in the server side, usually if I only 1 data to be sent, I never define the data in .ajax, like...
...
data: searchData,
...
And I can access the serialized data in server side just like...
$_POST['inputValue1'];
$_POST['inputValue2'];
etc...
But how I should do it if I have 2 or more data to send via .ajax, since it must be defined first.
Simply you can use as below
data: searchData+"&listPage="+pageNumber

When I sent the variable data through ajax loading_add.php page an error
is displayed:
Uncaught ReferenceError: profit is not defined.
What I tried so far is attached below.
var profit = (
Number($("#pro_price").val() - retail_price)
);
$.ajax({
type: "POST",
url: '../php/product/loading_add.php',
dataType: 'JSON',
data: {
profit: profit
};
In you php page just define variable as:
#$_POST['profit'];
you will not get undefined error again, hope this trick will help you :)
Your question is not clear.
But I share the valid way to send data via AJAX and retrieve the data in PHP Server Side..
var profit = (
Number($("#pro_price").val() - retail_price)
);
console.log(profit); // see in console log if `profit` is a valid variable or not
$.ajax({
type: "POST",
url: '../php/product/loading_add.php',
dataType: 'JSON',
data: {
profit: profit
}
}).done(function(result){
//do something after done AJAX
});
In server side, you must call variable $_POST['profit'] to retrieve the profit value.
I have a problem with my PHP, I'm doing an ajax post with jquery.
The problem: my PHP doesnt receive any POST, with GET there are no problems.
I'm using the last jquery version.
Ajax doesnt throw any error, I tried with error:function(...) and console.log.
idCat is a number, for example: 3
$nuevaFila and other undeclared variables are previously declared, they aren't constructive.
PHP returns well the HTML because I try any html and I receive it ok
The ajax code is this one:
$.ajax({
cache:false,
type:'post',
url:'admin/categoria_ajax_ad',
data: {id: idCat},
success: function(htmlFila) {
var nFila=$cFilas.find(".fila").size()+1;
$nuevaFila.html(htmlFila);
$nuevaFila.appendTo($cFilas);
},
});
Try using dataType (xml, json, script, or html) setting parameter like this depending on your return data type -
$.ajax({
cache:false,
type:'post',
url:'admin/categoria_ajax_ad',
data: {id: idCat},
dataType : "string"
success: function(htmlFila) {
var nFila=$cFilas.find(".fila").size()+1;
$nuevaFila.html(htmlFila);
$nuevaFila.appendTo($cFilas);
},
});
I have this for loop in jquery
$(document).ready(function() {
for(i=0; i<counter; i++)
{
dataCounter = i;
$.ajax({
url: 'file.php',
dataType: 'json',
data: dataCounter,
error: function(){
alert('Error loading XML document');
},
success: function(data){
$("#contents").html(data);
}
});
}
});
And then I want to bring in my dataCounter into the file.php as a variable and have it change each time so I can get different records in mysql in file.php, am I doing this right? How would the php portion look like? I know how pass variables to a php file with this method if I had a form, but I don't have a get or a post form to work with. Also, my variables are going to change.
Can someone help me? Thank you!
While I don't recommend running an ajax query inside of a loop, I am wiling to explain the data option for $.ajax(). Ideally, you pass an object as the data option, and it is translated by jQuery into a query string where each object property name is a key and its value is the value:
data: {
count: dataCounter
}
becomes
?count=1
in the query string of the ajax request if datacounter is equal to 1.
In PHP you would access it as $_GET['count'].
data needs to be a key-value pair, not just a value as you have it here. Try something like: (not tested)
$.ajax({
url: 'file.php',
dataType: 'json',
data: ({dataCounter : dataCounter}),
error: function(){
alert('Error loading XML document');
},
success: function(data){
$("#contents").html(data);
}
});
I'm trying to take values from a dropdown two boxes and send them to a PHP file which will draw an appropriate field from a mySQL database depending on the combination chosen and display it in a div without refreshing the page using AJAX. I have the second part sorted, but I'm stuck on the first part.
Here is the HTML: http://jsfiddle.net/SYrpC/
Here is my Javascript code in the head of the main document:
var mode = $('#mode');
function get() {$.post ('data.php', {name: form.him.value, the_key: #mode.val()},
function(output) {$('#dare').html(output).show();
});
}
My PHP (for testing purposes) is:
$the_key = $_POST['the_key'];
echo $the_key;
After I have it in PHP as a variable I can manipulate it, but I'm having trouble getting it there. Where am I going wrong? Thanks for your replies!
You need a callback function as well to have the server response to the POST.
$.post('ajax/test.html', function(data) {
$('.result').html(data);
});
This snippet will post to ajax/test.html and the anonymous function will be called upon its reply with the parameter data having the response. It then in this anonymous function sets the class with result to have the value of the server response.
Help ? Let me know and we can work through this if you need more information.
Additionally, $.post in jQuery is a short form of
$.ajax({
type: 'POST',
url: url,
data: data,
success: success
dataType: dataType
});
your jquery selectors are wrong:
html:
<select id="mode">
jquery selector:
$("#mode").val();
html:
<select name="player">
jquery selector:
$("select[name=player]").val();
You want to add a callback to your ajax request, its not too hard to do, here ill even give you an example:
$.ajax({
url: "http://stackoverflow.com/users/flair/353790.json", //Location of file
dataType: "josn",//Type of data file holds, text,html,xml,json,jsonp
success : function(json_data) //What to do when the request is complete
{
//use json_data how you wish to.;
},
error : function(_XMLHttpRequest,textStatus, errorThrown)
{
//You fail
},
beforeSend : function(_XMLHttpRequest)
{
//Real custom options here.
}
});
Most of the above callbacks are optional, and in your case i would do the following:
$.ajax({
url: "data.php",
dataType: "text",
data : {name: ('#myform .myinput').val(),the_key: $('#mode').val()},
success : function(value)
{
alert('data.php sent back: ' + value);
}
});
the ones you should always set are url,success and data if needed, please read The Documentation for more information.
i have a set of php function that i want to call on different events mostly onclick with jquery async (ajax).
The first function is called on load
$(document).ready(function()
{
$("#div2").hide('slow');
$("#div1").empty().html('<img src="ajax-loader.gif" />');
$.ajax(
{
type: "POST",
url: "WebFunctions.php",
data: {'func':'1'},
success: function(html)
{
$("#div1").show('slow').html(html)
}
});
The Data: {'func':'1'} --> is a switch statement on the php side
switch($_POST['func'])
{
case '1':
getParents();
break;
case '2':
getChilds(params);
break;
case '3':
getChildObjects(params);
break;
default:
}
"This functions are calls to a soap server" <-- irrelevant.
So when that function finishes i get an array which contains IDs and Names. I echo the names but i want the ID for reference so when i click on the echoed name i can call an other php function with parameter the ID of the name...
How do i get rid of the switch statement?? How do i call properly php functions and pass params to it??? How can i save this IDs so when i click on an item with that id an other php function is called??
Plz feel free to ask any question, any answer is welcome :)

$(document).ready(function()
{
$("#div2").hide('slow');
$("#div1").empty().html('<img src="ajax-loader.gif" />');
$.ajax(
{
type: 'post',
async: true,
url: "Parents.php",
data: {'id' : 12200},
dataType: "json",
cache: false,
success: function(json_data)
{
$("#div1").empty();
$.each(json_data, function(key, value)
{
$("#div1").append('<p class="node"><b>['+key+']</b> => '+value+'</p>');
$(this).data('id', key);
});
}
});
$("p.node").click(function()
{
var id = $(this).data('id');
alert('The ID is: ' + id);
});
});
I got json communication working but my problem is the data stuff,
when i click on a node the id is undefined... it gets printed but when i click on it oupsss.. so the problem is how can i properly attach the ID to each corresponding .. .
You can avoid the switch statement by using an MVC framework that routes your request to the proper function. For example, using CodeIgniter REST Server, you might have the following URL's to your functions:
http://myserver/my_api/parents
http://myserver/my_api/children
http://myserver/my_api/childObjects
You can then POST the parameters along with each AJAX request.
You would probably also want to return the ID you pass as part of the response, so it will be available when you make a request for the next function.
One solution for managing your ID's would be to encode your data as JSON. This will allow you to pass the whole PHP array to Javascript, and have it natively understand and read the ID's and Names.
To encode your PHP array as JSON, try this:
echo json_encode($my_array);
(You'll need PHP 5.2+ for this to work)
This will print out JSON data when the page is requested. Next, in your JavaScript add a "dataType" argument to your Ajax function call. Something like this:
// Get JSON Data and Save
$.ajax({
type: "POST",
url: "WebFunctions.php",
data: {'func':'1'},
dataType: "json",
success: function(json_data) {
$("#div1").data(json_data);
}
});
// Display the ID when clicked
$("#div1").click(function(){
var id = $(this).data('id');
alert('The ID is: ' + id);
});
This tells the Ajax function to expect JSON back.
When the success function is called you can access the "json_data" variable and find all the ID's and Names just as you had them in PHP. You'd then need to write some code to appropriately save those ID's and Names. They can then be used later on (ie. when you click on the button etc).
EDIT: I've updated the code above. The JSON data is now associated with the HTML element "#div1", so you can refer back to it in the future. I've also added a simple click event. Whenever the element is clicked, it's ID will be displayed.
