I want to do an update statement in my database, after an element gets dropped on a jQuery UI droppable element.
$("#pictures th div").droppable({drop: function(ev, ui) {
alert('You filled this box with a picture');
var this_id = $(ui.draggable).attr("alt");
var draggableId = ui.draggable.attr("id");
}
I know how to get the information (see the code above) I need, but how can I put them now into the database ?
Thank you !
At this point, you can use jQuery's $.post() method to post to a PHP file you've written. In the $.post(), you can pass the ids you would like to have written to your database.
So something like this:
$.post("/save.php", { imageId: this_id, draggedId: draggableId }, function (data) {
alert("success!");
});
Post the variable values to other page lyk this:
$.ajax({
type: "POST",
url: "data.php",
data: "Cat=" + id + "&Wid=" + WID
});
and then on data.php page get the values lyk this:
$Cat=$_POST['Cat'];
$WID=$_POST['Wid'];
simply store them in database by using insert query,hope it will help you.

I am attempting to use AJAX to generate PHP to be displayed inside of a div based on the ID of the link clicked. (I haven't dealt with HTML formatting yet, just want to figure this out first)
My Code:
<script type="text/javascript">
jQuery(document).ready(function()
{
$(".myClass h3").click(function(){
var clickID = $(this).attr('id'); //For sake of argument lets say id = 1.
$.ajax({
url: 'landingPage.php',
data: {ProductIDNumber: clickID},
success: function(html) {
$('#container').append(html);
}
});
});
});
</script>
I have dealt with getting the PHP to run when the url is landingPage.php?ProductIDNumber=1 and that all works properly, I just don't quite grasp how to return the resultant HTML.
Edits made and commented on.
You need to include success, which is run once the response is received, similar to;
<script type="text/javascript">
jQuery(document).ready(function()
{
$(".myClass h3").click(function(){
var clickID = $(this).attr('id'); //For sake of argument lets say id = 1.
$.ajax({
url: 'landingPage.php',
data: {
ProductIDNumber : clickID
},
success: function(html) {
// Do what you need to here with 'html'
$('#container').append(html);
}
});
});
</script>
As Alvaro said the structure of the data was also incorrect
Here's a link to the jQuery docs where you can find out more about the parameters and options you have (such as handling fails etc)
the data is wrong,
it is like this:
data: {varname: value, varname1: value},
I'me trying to implement an on/off button on a php loop but I can't make it work because of the id of jQuery event. How can I get the correct id on click and pass it to the rest of the script?
The problem is in the $('#myonoffswitch')...
<script type="text/javascript">
$(document).ready(function(){
$('#myonoffswitch').click(function(){
var myonoffswitch=$('#myonoffswitch').val();
var wnfID=$('#wnfID').val();
if ($("#myonoffswitch:checked").length == 0) {
var a="2";
var b=wnfID;
} else {
var a="3";
var b=wnfID;
}
$.ajax({
type: "POST",
url: "ajax_wnf_status.php",
data: "statusWnf="+a+"&wnfID="+b,
success: function(html) {
$("#display").html(html).show();
}
});
});
});
</script>
I'm generating different id's for the loop rows (ex: id="#myonoffswitch1" ; id="#myonoffswitch2"; etc).
I'm not certain I fully understand the question, but .val() will not get the ID of an element. You should use .attr('id') instead.
Also, it looks like you're trying to format data for a GET request, not a POST.
If I understand the question correctly, I think you're looking for
event.target.id
where 'event' is passed in to your handler:
('#myonoffswitch').click(function(event){
id = event.target.id
. . .
Though at that point, you might not need the id, since you can just use event.target directly.
I have a table with dynamic data from database, each row consist of a text filed and 2 link (accept or reject). then if user clicks on any of these link, the row will disappear and the rest of the rows are only visible in table.
I get ID of each row with ajax by clicking on each link, however I also need to get the text-field value.
how can I get it?
I need to have in ajax cause after getting value I need to insert in database with php+sql.
this is my ajax part for link:
$('a.accept').click(function(d) {
d.preventDefault();
var parent = $(this).parent();
$.ajax({
type: 'get',
url: 'Test.php',
data: 'ajax=1&accept=' + parent.attr('id').replace('record-',''),
beforeSend: function() {
parent.animate({'backgroundColor':'#fb6c6c'},300);
},
success: function() {
parent.slideUp(300,function() {
parent.remove();
});
}
});
});
});
how can I include text filed value in it?
please comment me which I'm really in need to solve it,
Thanks
You can add manually your text to the GET request.
(snippet)
data: 'ajax=1&accept=' + parent.attr('id').replace('record-','') + '&text=VALUE',
Substitute text with the name you want to be received in PHP. Substitute VALUE with the text entered on the page that you want to grab - and don't forget to encode the value.
You will need the name of id of the textfield first. Then you could do something like this:
var textboxvalue = $('name or id of textfield').val();
Then you will need to append this value to your data string:
data: 'ajax=1&textvalue='+textboxvalue+'accept=' + parent.attr('id').replace('record-',''),
Then you can use $_GET['textvalue']; to get the value of textbox.
Use following and you're good to go. Also you had extra '});' at the end line of JS fragment. I had it removed. But make sure you give id to text fields in following pattern : text-fld-RECORD_ID where RECORD_ID is the ID of the record.
$('a.accept').click(function(d) {
d.preventDefault();
var parent = $(this).parent();
var id = parent.attr('id').replace('record-','');
//make sure that text field has ID in pattern 'text-fld-RECORD_ID'
var text_fld = $('#text-fld-'+id).val();
$.ajax({
type: 'post', // I suggest using post; get will be harmful in such occasions
url: 'Test.php',
data: {ajax:1,accept:id,text:text_fld},
beforeSend: function() {
parent.animate({'backgroundColor':'#fb6c6c'},300);
},
success: function() {
parent.slideUp(300,function() {
parent.remove();
});
}
});
});
I want to basically create a link which says:
Click here to show contact information
Upon clicking it, it will ping a script via an ajax request, the ajax request will look up the user table where the ID is what is contained in the alt tag, it will return a certain field from the database and then the div will change from this link, to a contact number.
I'm sure some of you have seen this done before, for example:
Click to see persons phone number
They click it, and it changes to their phone number.
How would I go about doing this? I want to do it using ajax instead of having the phone number in the source code, because that really defeats the purpose of them having to click to reveal if bots can get it from the source code.
Thanks :)
Somethign along the lines of
$("#reveal").click(function(){
$.get('getphoneNumber.php',{id:$(this).attr('alt')}, function(data) {
$('#reveal').html(data);
});
});
with a php script called getphoneNumber.php that accepts a get parameter of id
Try this one
$('#reveal').click(function () {
var th = $(this);
$.get('/get-the-phone-number', { id: th.attr('alt') }, function (response) {
th.text(response);
});
});
Also, I'd recommend you put the id number inside a data-contact-id attribute and access it via th.data('contact-id') instead of using the alt attribute. Ignore me if you have other reasons to do this.
$("#reveal").live('click',function(event) {
var link = $(this).attr('alt');
var dataString = 'alt=' + link ;
$.ajax({
type: "POST",
url: "url",
cache:false,
data: dataString,
success: function(data){
this.href = this.href.replace(data);
}
});
}
Click here to show contact information
<div id="myHiddenDiv"></div>
$("#reveal").click(function(){
$.get("test.php", { id: $(this).attr("alt") },
function(data){
$("#myHiddenDiv").html(data);
$("#myHiddenDiv").show();
});
});
This example works assuming you've only got one of these "plugins" on your site, if you'll have multiple, use this:
Click here to show contact information
<div class="myHiddenDiv"></div>
$(".reveal").click(function(){
var divSelector = $(this).next("div");
$.get("test.php", { id: $(this).attr("alt") },
function(data){
divSelector.html(data);
divSelector.show();
});
});
I have a simple AJAX function to send an id of an object to a php page
My function looks like this:
$(function(){
$("a.vote").click(function(){
//get the id
the_id = $(this).attr('id');
alert(the_id);
//ajax post
$.ajax({
type: "POST",
data: "?id="+the_id,
url: "vote.php",
success: function(msg)
{
$("span#message"+the_id).html(msg);
}
});
});
});
My vote.php looks like this:
session_start();
if(isset($_SESSION['user'])) {
// db setup removed
// insert vote into db
$q = "UPDATE votes SET vote = vote + 1 WHERE id = " . $_POST['id'];
mysql_query($q);
echo "You sent " . $_POST['id'];
}
When I execute my AJAX function, it appears that the vote.php is never run
I know that my AJAX function is being called correctly, because alert(the_id); is popping up with the correct ID.
I know my vote.php is functioning correctly because I can run an HTML method="post" with a textbox named "id", and it will update the database correctly.
Can anyone see what's wrong?
Thank you
You're trying to send your variables in the URL, not as POST variables. Should be something like:
$(function(){
$("a.vote").click(function(){
//get the id
var the_id = $(this).attr('id');
alert(the_id);
//ajax post
$.ajax({
type: "POST",
data: {id:the_id},
url: "vote.php",
success: function(msg)
{
$("span#message"+the_id).html(msg);
}
});
});
});
Your data should be as included as an object, not as a string URL. Check out the examples on the jquery API page for more info on this!
The principal thing I see in your code that doesn't look right is data: "?id="+the_id,. The ? is unnecessary, and illogical for a post request. Do the following instead:
data: {
id: the_id
}
This lets jQuery do the URL-encoding for you.
As an additional point, you do $(this).attr(id). This is very inefficient. Do this.id instead, for exactly the same effect hundreds of times quicker at least 20 times quicker.
Your data value shouldn't need a question mark at the beginning.
