After hours of trying to get this to work, i want to ask you :)
So i have a php Page that can display files from a server. Now I can edit
the files with a editor plugin.
Textarea is the tag where the editor gets rendered.
To save the changed text from the editor, I have a button that gets the innerHTML from the surrounding pre tag of the text with javascript.
I now want to pass that variable via ajax to a php variable on the site get.php,
so I can save it locally and send it to the server.
The problem is, that there is no reaction at all, if i click the "Save" button. I tested a lot of answers from similar ajax functions here, but none of them gave me a single reaction :/
php main
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
...
echo "<textarea><pre id='textbox'> ";
echo $ssh->exec($display);
echo "</textarea></pre>";
echo '<input type="button" value="Save File" id="butt">';
echo "<script>
var show = document.getElementById('textbox').innerHTML;
$(document).ready(function() {
$('#butt').click(function() {
$.ajax({
type: 'POST',
url: 'get.php',
data: {'variable': show},
success: function(data){
alert(data);
}
});
});
});
</script>";
...
get.php
if (isset($_POST["variable"])){
$show =$_POST["variable"];
echo $show;
}
Edit:
This is the actual working state:
echo "<textarea id='textbox'><pre> ";
echo $ssh->exec($display);
echo "</pre></textarea>";
echo '<input type="button" value="Save File" id="butt">';
echo "<script>
$(document).ready(function() {
$('#butt').click(function() {
var show = document.getElementById('textbox').value;
$.ajax({
type: 'POST',
url: 'get.php',
data: {'variable': show},
success: function(data){
alert(data);
},
});
});
});
</script>";
You have an error in the data: {'variable': show)} part. It should be: data: {variable: show}. Also you should use Firebug or Firefox developer tools for these kind of problems. A lot easier to see whats wrong.
I would suggest small changes to see if everything is running as it should.
I can see that pre tag is behind textarea closing tag - try to change it
Try putting var show = document.getElementById('textbox').innerHTML; inside of the ,,butt" function
Then I can see your problem here data: {'variable': 'show')}, - you are sending 'show' as a string - remove quotes to send it as a variable which will appear as a POST value in PHP site.
with this should work:
$.ajax({
type: 'POST',
url: 'get.php',
data: {variable: show)},
success: function (data){
alert(data);

I am not a technical person, but a semi technical business man and learning/creating my own website.
I want to pass JS variables (from html page) to my another Php page.
NOTE** I am getting redirect with required parameters in URL (title). Now, I want to pass another variables, but not through the URL
Here is my html page code:
$.ajax({
type: 'GET',
url: "'search_result.php' + '?title=' + dtitle",
data: { selectedFT: "hello"}
});
And my php page code:
<php>
$fueltype = $_GET['selectedFT'];
echo $fueltype;
// I will be using this variable as $fueltype in my further code.
?>
Appreciate your help. I wasted many hours to solves this through google, but nothing fits.
Please provide me sample so that I can understand easily.
Post method may help you:
$.ajax({
type: 'post',
data: {
title: dtitle,
selectedFT: "hello"
},
url: 'search_result.php'
});
In Your PHP page add:
<php>
$fueltype = $_POST['selectedFT'];
echo $fueltype;
// I will be using this variable as $fueltype in my further code.
?>
Try this solution.
let dtitle = "Hello";
$.ajax({
type: 'GET',
url: `search_result.php?title=${dtitle}`,
});
PHP file
<?php
$fueltype = $_GET['title'];
echo $fueltype;
?>
I have this button
<button id="<?php echo $u['id']?>" name="activation" onclick="handleButton(this);" type="submit" class="btn btn-success"></button>
And this button related to this
<td id="<?php echo $u['id']?>"><?php echo $u['id']?></td>
I'm using this script to send value of button to my php controller
function handleButton(obj) {
var javascriptVariable = obj.id;
// alert (javascriptVariable);
$.ajax({
type: "POST",
url: "<?php echo base_url(); ?>index.php/admin/active_users",
dataType: 'text',
data: 'myname='+javascriptVariable,
success: function (data){
}
});
}
When I use alert, the result of javascriptVariable is correct and I want it in my controller so I'm trying in my controller to do this:
if(isset($_POST['activation']))
{
$name = $this->input->post('myname');
var_dump($name);
}
But I get null value, what is the wrong?
When you pass data from the browser via AJAX only the data you pass in the data: parameter is sent to the PHP script.
So if you want to test for activation in the PHP script you must actually send that parameter
Also see the amendment to the data: parameter creation below. Its easier to read and a lot easier to code correctly when passing more than one parameter as you dont have to remember &'s and + concatenation.
function handleButton(obj) {
obj.preventDefault();
$.ajax({
type: "POST",
url: "<?php echo base_url(); ?>index.php/admin/active_users",
dataType: 'text',
data: {activation: 1, myname: obj.id}, // add parameter
success: function (data){
alert(data);
}
});
}
Now the PHP will see 2 parameters in the $_POST array activation and myname
if(isset($_POST['activation']))
{
$name = $_POST['myname'];
var_dumb($name);
}
Or if you are using a framework which I assume you are
if(isset($this->input->post('activation')) {
$name = $this->input->post('myname');
var_dumb($name);
}
EDIT:
Spotted another issue your button has an attribute type="submit" this will cause the javascript to run AS WELL AS the form being submitted in the normal way.
Remove the type="submit" attribute and to be doubly sure that the form will not be submitted as well as the AJAX add a call to preventDefault(); as well before the AJAX call
Since the php script is conditioned by a second POST variable [if(isset($_POST['activation']))], you should post that as well.
function handleButton(obj) {
var javascriptVariable = obj.id;
// alert (javascriptVariable);
$.ajax({
type: "POST",
url: "<?php echo base_url(); ?>index.php/admin/active_users",
dataType: 'text',
data: 'myname='+javascriptVariable+'&activation=1',// <-- RIGHT HERE
success: function (data){
alert(data);
}
});
}
SIDE NOTE: you could also echo instead of dump the variable:
if(isset($_POST['activation']))
{
echo $this->input->post('myname');
}
Try this in your ajax function :
function handleButton(obj) {
var javascriptVariable = obj.id;
//alert (javascriptVariable);
$.ajax({
type: "POST",
url: "<?php echo base_url(); ?>index.php/admin/active_users",
dataType: 'text',
data: {myname: javascriptVariable},
success: function (data) {}
});
}
And in your PHP script, you can do $_POST['myname'] to get it (maybe $this->input->post('myname') can work, you can test it)
Look two id
<button id="<?php echo $u['id']?>" name="activation" onclick="handleButton(this);" type="submit" class="btn btn-success"></button>
AND
<td id="<?php echo $u['id']?>"><?php echo $u['id']?></td>
For both html elements id is same.It can not be used with in the same page.This may cause a problem for you...
I know this question have been asked alot but none of the answer are related to my case ,I have a button ,onclick it should call a javascript function send it a php variable,and ajax would call a php file via post and send that vriable and the php file updates my table
so here is the onclick event first
<button class="button button6 " onclick="incrementclicks('<?php echo $id; ?>');">increment</button>
it should send a variable called $id to the javascript function
<script type="text/javascript">
function incrementclicks(id) {
$.ajax({
url: "increment.php",
data: "id=" + id,
type: "POST"
});
}
</script>
and the php file increment.php (I'm 100% sure it connects to the server just fine )
<?php
require_once 'dbconnect.php';
$db_handle = new DBController();
$id=$_POST["id"];
$q="UPDATE clicks SET linkclicks = linkclicks + 1 WHERE id = '".$id."'";
$result = mysql_query($q);
?>
it doesn't increment, I don't understand what did i do wrong here
First of all you can debug your code on the php by doing
echo $id;
exit();
My quess is that your are missing something there..
Use this method of ajax to check the issue.And if error found check in console for the issue
$.ajax({
url: "increment.php",
type: "post", //send it through post method
data: {
id:id
},
success: function (response) {
alert("success");
},
error: function (xhr) {
//Do Something to handle error
alert("some error found");
}
});
NB:Try to add type="button" to your button for not to reload
<button class="button button6 " onclick="incrementclicks(5);" type="button">increment</button>
I just want to answer this if anyone have future problems like this
The problem is I forgot to add script src at the beginning
<script src="https://code.jquery.com/jquery-2.1.1.min.js" type="text/javascript"></script>
after adding this my code worked just fine :)
I've got an issue with an ajax call and .html(), as you can see with the javascript below i'm using the geoloc callback to make a ajax call and refresh the content of a div.
The id of the div can be either "result-shops-ajax-desktop" or "result-shops-ajax-mobile" and in my case the php variable $type = "desktop"
The problem is that the content of the div is not reloaded despite the use of .html()
My ajax call is working because msg.response got the content i want. The .html() seems to work because the alert show the content of msg.response but I can't see it on the page :/
Another thing is weird when i put directly the id of the div, the content is shown, but when i echo the $type it's not working despite the fact that the html produced is good (the id of the div is "result-shops-ajax-desktop").
I hoped i made myself clear with my bad english, i would really appreciate any help for this weird issue.
Thanks !
Here is the javascript in my php file :
<script type="text/javascript">
jQuery.noConflict();
jQuery(document).ready(function($){
function geolocShow(position) {
$.ajax({
type: "POST",
url: "<?php echo $this->getUrl('shops/index/checkavailability'); ?>",
dataType : "json",
data: "sku=<?php echo $product->getSku(); ?>&lat="+position.coords.latitude+"&lng="+position.coords.longitude,
success: function(msg){
$("#result-shops-ajax-<?php echo trim($type); ?>").html(msg.response);
alert($("#result-shops-ajax-<?php echo trim($type); ?>").html());
}
});
}
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(geolocShow);
}
});
</script>
The html generated:
jQuery.noConflict();
jQuery(document).ready(function($){
function geolocShow(position) {
$.ajax({
type: "POST",
url: "http://localhost/shops/index/checkavailability/",
dataType : "json",
data: "sku=abc&lat="+position.coords.latitude+"&lng="+position.coords.longitude,
success: function(msg){
$("#result-shops-ajax-desktop").html(msg.response);
alert($("#result-shops-ajax-desktop").html());
}
});
}
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(geolocShow);
}
});
Try this: jQuery(document).ready(function($){ this line change to $(window).load(function(){
I've search for many solution but without success.
I have a html form;
<form id="objectsForm" method="POST">
<input type="submit" name="objectsButton" id="objectsButton">
</form>
This is used for a menu button.
I'm using jquery to prevent the site from refreshing;
$('#objectsForm').on('submit', function (e) {
e.preventDefault();
$.ajax({
type: 'post',
url: '/php/objects.php',
data: $('#objectsForm').serialize(),
success: function () {
alert('success');
}
});
});
In my php file I try to echo text to the body of my site;
<?php
if (isset($_POST["objectsButton"])){
echo '<div id="success"><p>objects</p></div>';
} else {
echo '<div id="fail"><p>nope</p></div>';
}
?>
I know the path to my php file is correct, but it doesn't show anything? Not even the "fail div".
Does anyone has a solution for me?
Thanks in advance!
The success function takes two parameters. The first parameter is what is returned from the php file. Try changing it to:
success: function (xhr){ alert(xhr);}
Based in your php source..
$.ajax({
type: 'post',
dataType: "html", // Receive html content
url: '/php/objects.php',
data: $('#objectsForm').serialize(),
success: function (result) {
$('#divResult').html(result);
}
});
PHP scripts run on the server, that means any echo you do won't appear at the user's end.
Instead of echoing the html just echo a json encoded success/ failure flag e.g. 0 or 1.
You'll be able to get that value in your success function and use jQuery to place divs on the web page.
PHP:
<?php
if (isset($_POST["objectsButton"])){
echo json_encode(1); // for success
} else {
echo json_encode(0); // for failure
}
?>
jQuery:
var formData = $('#objectsForm').serializeArray();
formData.push({name:this.name, value:this.value });
$.ajax({
type: 'post',
url: '/php/objects.php',
dataType: 'json',
data: formData,
success: function (response) {
if (response == 1) {
alert('success');
} else {
alert('fail');
}
}
});
EDIT:
To include the button, try using the following (just before the $.ajax block, see above):
formData.push({name:this.name, value:this.value });
Also, have the value attribute for your button:
<input type="submit" name="objectsButton" value="objectsButton" id="objectsButton">
