I have a Leaflet map, and a text input. I want to take the address from the textbox, run it through a PHP script, and get the result all through jQuery.
Here is my form:
<form id="mapcheck" method="POST" action="geo.php">
<input id="largetxt" type="text" name="checkAddress">
<input id="button" type="submit" name="submit" value="Check">
</form>
Here is part of the PHP:
<?php
if (isset($_POST["checkAddress"])) { //Checks if action value exists
$checkAddress = $_POST["checkAddress"];
$plus = str_replace(" ", "+", $checkAddress);
$json = file_get_contents('https://maps.googleapis.com/maps/api/geocode/json?address=' . $plus . '&key=GMAPSKEY');
$obj = json_decode($json);
$mapLat = $obj->results[0]->geometry->location->lat;
$mapLng = $obj->results[0]->geometry->location->lng;
$coords = ('' . $mapLat . ', ' . $mapLng . '');
return $coords;
}
?>
And the jQuery:
$(document).ready(function() {
$("#button").click(function(){
$.ajax({
url: "geo.php",
method: "POST",
data: {
checkAddress: $("#largetxt").val()
},
success: function(response){
console.log(response);
}
});
});
});
I need to listen on submit of the form via jQuery (NOT PHP), run it through a geocode script, then take that result and put it through regular JavaScript (Leaflet map.) I have played around with the AJAX feature of jQuery to no avail. There is a very simple solution to this, but I have not figured it out.
UPDATE: Problem resolved, thanks Vic.
You would need AJAX. Remove the form element but keep the inputs.
$("#button").click(function(){
$.ajax({
url: "geo.php",
method: "POST",
data: {
checkAddress: $("#largeText").val()
},
success: function(response){
console.log(response);
//your script
}
})
});

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'm trying to display two PHP echo messages from a seperate PHP file onto my HTML body page. Whenever you click the submit button the echo message should popup in the HTML page without redirecting me to the PHP page.
I need to connect to my two files through Javascript so I wrote a script attemtping to connect the HTML file with the PHP file.
My HTML:
<div id="formdiv">
<form action="phpfile.php" method="get" name="fillinform" id="fillinform" class="js-php">
<input id="fillintext" name="fill" type="text" />
<input type="submit" id="submit1" name="submit1">
</form>
</div>
phpfile.php:
$q = $_GET['fill'];
$y = 2;
$work = $q * $y;
$bork = $work * $q;
echo json_encode($work) ."<br>";
echo json_encode($bork);
Javascript:
$(".js-php").submit(function()
var data = {
"fill"
};
data = $(this).serialize() + $.param(data);
$.ajax({
type:"GET",
datatype:"json",
url:"phpfile.php",
data: data,
success: function (data){
$(".formdiv").html(
""
"Your input: ")
}
You attached your logic to .submit() event and if you don't prevent default action, the form will be submitted to server. You can prevent it that way:
$(".js-php").submit(function(e) {
// your code goes here
e.preventDefault();
});
You'll have to append the data to your div like this:
success: function (data) {
$(".formDiv").append("Your input: " + data);
}
As per your html you should try this below code :
If you want to replace the whole html inside the div having id="formdiv"
success: function (data){
$("#formdiv").html("Your input: "+data)
}
or
success: function (data){
$("#formdiv").text("Your input: "+data)
}
If you want to append data to the div having id="formdiv"
success: function (data){
$("#formdiv").append("Your input: "+data)
}
Add curly braces after $(".js-php").submit(function(e) and close it after your ajax ends.
Add e.preventDefault() before you call ajax so it will not redirect
you to phpfile.php
Add alert(data) inside your function called at success of ajax.
there is a syntax error n line $(".formdiv").html("""Your input: ");
Your updated code should look like.
$(".js-php").submit(function(e){
var data = {
"fill"
};
data = $(this).serialize() + $.param(data);
$.ajax({
type:"GET",
datatype:"json",
url:"phpfile.php",
data: data,
success: function (data){
alert(data);
}
}
I have a form with an input field for a userID. Based on the entered UID I want to load data on the same page related to that userID when the user clicks btnLoad. The data is stored in a MySQL database. I tried several approaches, but I can't manage to make it work. The problem is not fetching the data from the database, but getting the value from the input field into my php script to use in my statement/query.
What I did so far:
I have a form with input field txtTest and a button btnLoad to trigger an ajax call that launches the php script and pass the value of txtTest.
I have a div on the same page in which the result of the php script will be echoed.
When I click the button, nothing happens...
Test.html
<script type="text/javascript" src="http://code.jquery.com/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery.validate/1.7/jquery.validate.min.js"></script>
<script>
//AJAX CALL
function fireAjax(){
$.ajax({
url:"testpassvariable.php",
type:"POST",
data:{userID:$("#txtTest").val(),},
success: function (response){
$('#testDiv').html(response);
}
});
}
</script>
</head>
<body>
<form name="testForm" id="testForm" action="" method="post" enctype="application/x-www-form-urlencoded">
<input type="text" name="txtTest" id="txtTest"/>
<input type="button" id="btnLoad" name="btnLoad" onclick="fireAjax();"
<input type="submit" name="SubmitButton" id="SubmitButton" value="TEST"/>
</form>
<div id="testDiv" name="testDiv">
</div>
</body>
The submit button is to insert updated data into the DB. I know I have to add the "action". But I leave it out at this point to focus on my current problem.
testpassvariable.php
<?php
$player = $_POST['userID'];
echo $player;
?>
For the purpose of this script (testing if I can pass a value to php and return it in the current page), I left all script related to fetching data from the DB out.
As the documentation says 'A page can't be manipulated safely until the document is ready.' Try this:
<script>
$(document).ready(function(){
//AJAX CALL
function fireAjax(){
$.ajax({
url:"testpassvariable.php",
type:"POST",
data:{userID:$("#txtTest").val(),},
success: function (response){
$('#testDiv').html(response);
}
});
}
});
</script>
You need to correct two things:
1) Need to add $(document).ready().
When you include jQuery in your page, it automatically traverses through all HTML elements (forms, form elements, images, etc...) and binds them.
So that we can fire any event of them further.
If you do not include $(document).ready(), this traversing will not be done, thus no events will be fired.
Corrected Code:
<script>
$(document).ready(function(){
//AJAX CALL
function fireAjax(){
$.ajax({
url:"testpassvariable.php",
type:"POST",
data:{userID:$("#txtTest").val(),},
success: function (response){
$('#testDiv').html(response);
}
});
}
});
</script>
$(document).ready() can also be written as:
$(function(){
// Your code
});
2) The button's HTML is improper:
Change:
<input type="button" id="btnLoad" name="btnLoad" onclick="fireAjax();"
To:
<input type="button" id="btnLoad" name="btnLoad" onclick="fireAjax();"/>
$.ajax({
url: "testpassvariable.php",
type: "POST",
data: {
userID: $("#txtTest").val(),
},
dataType: text, //<-add
success: function (response) {
$('#testDiv').html(response);
}
});
add dataType:text, you should be ok.
You need to specify the response from the php page since you are returning a string you should expect a string. Adding dataType: text tells ajax that you are expecting text response from php
This is very basic but should see you through.
Change
<input type="button" id="btnLoad" name="btnLoad" onclick="fireAjax();"/>
Change AJAX to pass JSON Array.
data = $(this).serialize() + "&" + $.param(data);
$.ajax({
type: "POST",
dataType: "json",
url: "action.php",
data: data,
....
// action.php
header('Content-type: application/json; charset=utf-8');
echo json_encode(array(
'a' => $b[5]
));
//Connect to DB
$db = mysql_connect("localhst","user","pass") or die("Database Error");
mysql_select_db("db_name",$db);
//Get ID from request
$id = isset($_GET['id']) ? (int)$_GET['id'] : 0;
//Check id is valid
if($id > 0)
{
//Query the DB
$resource = mysql_query("SELECT * FROM table WHERE id = " . $id);
if($resource === false)
{
die("Database Error");
}
if(mysql_num_rows($resource) == 0)
{
die("No User Exists");
}
$user = mysql_fetch_assoc($resource);
echo "Hello User, your number is" . $user['number'];
}
try this:- for more info go here
$(document).ready(function(){
$("#btnLoad").click(function(){
$.post({"testpassvariable.php",{{'userID':$("#txtTest").val()},function(response){
$('#testDiv').html(response);
}
});
});
});
and i think that the error is here:-(you wrote it like this)
data:{userID:$("#txtTest").val(),}
but it should be like this:-
data:{userID:$("#txtTest").val()}
happy coding :-)
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">
I'm learning js and jquery. I will post values as array with jquery ajax and in php code I will use it with foreach loop.
<select name="passenger['+i+'][nationality]">
<option value="GRE">GRE</option>
...
</select>
<input name="passenger['+i+'][gsm]" value="">
I have a form like that (for example). In php code I will use this names like that :
$passengers = $_POST['passenger']
foreach ($passengers as $i => $passenger) {
echo $passenger['nationality'] . '<br>';
echo $passenger['gsm'] . '<br>';
}
But to use in php I must post with jquery ajax. But I cant get array passenger with jquery to post as passenger array.
JS CODES
I need a passenger variable.
jQuery.ajax({
url: link,
type: "POST",
data: {passenger : passenger},
dataType: "json",
success: function(s) {
},
error: function() {
}
});
You can use serialize to get all the values within a form. So your JS can be:
$.post( link , $( "#testform" ).serialize() , function() {
alert('Succes');
});
