I have a set of members who have stored their login credentials (usr | pwd) of other websites as our partners. As is the situation, I am supposed to provide them just a text link and submit a form upon clicking that link.
// Getting values from db and storing them in javascript variables
<script type="text/javascript">
// values from db stored in javascript variables
var at_Cara = "<? echo $at;?>";
var ln_Cara = "<? echo $ln;?>";
var wd_Cara = "<? echo $pw;?>";
</script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
<script type="text/javascript">
// I am submitting a form with hidden values, which is as follows:
$(document).ready(function() {
$("#goto").click(function() {
var site = "http://franka.finexp.net/login.aspx";
$('<input>').attr({type: 'hidden',id: 'Auto',name: 'Auto',value: at_Cara}).appendTo('#valgoogexp');
$('<input>').attr({type: 'hidden',id: 'LoginName',name: 'LoginName',value: do_ln_Cara}).appendTo('#valgoogexp');
$('<input>').attr({type: 'hidden',id: 'Password',name: 'Password',value: wd_Cara}).appendTo('#valgoogexp');
$("#valgoogexp").attr("action", site);
$("#valgoogexp").submit();
});
return false;
});
</script>
<a href="javascript:void(0);" id="goto" >Research Tool</a>
<form id="valgoogexp"></form>
The problem is that the form submits twice upon clicking the link. And subsequently the landing page says its a string error.

I'm using emailjs to send email through my free subdomain website.There are two problems with it
1). My emailjs account-id, service-id and template-id is getting public so anybody can access it and send email through it.
2). to solve it I used following code but it steel appears in browser "inspect Element"(Developer tool).
<?php echo "
<script>
(function(){
emailjs.init(my user id);
})();
</script>" ; ?>
<?php
echo "<script src='js/formfilled.js'></script>";
?>
now my form submiting button is like this
<button onclick="email();">
Send
</button>
now my formfill file is like this
var myform = $("form#myform");
function email(){
var service_id = "default_service";
var template_id = "xxxxxxxxx";
myform.find("button").text("Sending...");
emailjs.sendForm(service_id,template_id,"myform")
.then(function(){
alert("Sent!");
myform.find("button").text("Send");
}, function(err) {
alert("Send email failed!\r\n Response:\n " + JSON.stringify(err));
myform.find("button").text("Send");
});
}
problem is that when I click the button rather than sending an email it reload the page .
Sorry if it is too silly i am totally beginner and Thanks in advance.
UPDATE
it is working if i put the code in the same file(not using external js)
code:--
<head>
<script type="text/javascript">
(function(){
emailjs.init("xxxxxxxxxxxxxxxxxxxxx");
})(); </head>
</script>
<body>
<!-- form is here-->
<script>
var myform = $("form#myform");
myform.submit(function(event){
event.preventDefault();
// Change to your service ID, or keep using the default service
var service_id = "default_service";
var template_id = "xxxxxxxxxxxxxxxxxxx";
myform.find("button").text("Sending...");
emailjs.sendForm(service_id,template_id,"myform")
.then(function(){
alert("Sent!");
myform.find("button").text("Send");
}, function(err) {
alert("Send email failed!\r\n Response:\n " + JSON.stringify(err));
myform.find("button").text("Send");
});
return false;
});
</script>
</body>
but if i put this code in formfilled.js it is not working.
what would be the reason behind it?
Answer:
to use
event.preventDefault();
and loading the file before the button is loaded.
I am new and just doing practices i just did:
var i= [["j.php?i=1"]]; and it sent value to php and prints but when i want some input from user it does nothing. For example:
file j.js
var input = "hello";
var send= [["j.php?i="+input]];
and in j.php
<?php
$e=$_GET['i'];
echo $e;
?>
Any idea or i am totally wrong? I am trying to have some variation. And i really did with window.location.href. But I just want to know how to do in this way var send= [[]]. Thanks
Edit:
your question is not very clear, maybe try this:
var input = "hello";
var url = "/j.php?i=" + input;
var send = [[url]];
But, it's not clear to me what you want to do with your send variable...
Original
You have to send the data to the server either using a a tag (GET method), a form (POST method) or an Ajax request (any Http verb):
<!-- Here you give a unique id to your link -->
<a id="link" href="">your link</a>
<script>
var i = "Hello";
// wait for page to be loaded
document.addEventListener("DOMContentLoaded", function(event) {
// change the href attribute of the link with the id equal to 'link'
// with whatever data contained in the i variable
// this is done after the page is loaded
document.getElementById("link").href = "/j.php?i=" + i;
});
</script>
Then, when you just click the link, it will send the variable named i containgin the value Hello to your php page.
You could also do it in this way:
<a id="link2">your link</a>
<script>
var i = "HELLO";
// wait for page to be loaded
document.addEventListener("DOMContentLoaded", function(event) {
// here we are telling javascript to change the url
// in the browser when the user clicks the link
document.getElementById('link2').onclick = function() {
window.location = '/j.php?i=' + i
}
});
</script>
I'm new to jquery and ajax. I'm trying to get my first ajax script to work, but it's not working and I need some assistance, please.
I have a php page that is supposed to post to another php page, where the latter will do some processing and get some files to get zipped and download. The user needs to input a starting and ending date, and the second php script will use this information to prepare the data. This functionality works perfectly fine without jquery, but doesn't work when I add jquery.
What do I want to achieve? I want to post in the to the same php page and get the post output in a <div></div> tag.
My first php page contains (downloadPage.php):
<script src="https://code.jquery.com/jquery-1.11.3.js"></script>
<form action="doDownload.php" method="post" id="dateRangeID">
<input id='time1' class='input' name="datefield1" style="text-align:center;"/>
<input id='time2' class='input' name="datefield2" style="text-align:center;"/>
<input type="submit" value="Download Data" name="submit" id="submitButton">
</form>
<div id="result"></div> <!-- I would like it to post the result here //-->
The second page (doDownload.php),
<div id="content">
<?php
if(isset($_POST['submit']))
{
$dateVal1 = $_POST['datefield1'];
$dateVal2 = $_POST['datefield2'];
if($dateVal1 != $dateVal2)
{
header('Content-Type: application/zip');
header('Content-disposition: attachment; filename="file.zip"');
$fullListOfFiles = $downloadFullTmpFolder.$filesList;
$command = "sudo $ldlib -u myuser /usr/bin/python3 $downloadScriptFile -datadir $gnomeDataDir -time1 $dateVal1C -time2 $dateVal2C -outdir $downloadFullTmpFolder > debug_download.txt 2>&1";
$output = shell_exec($command);
$fp = popen('cat '.$fullListOfFiles.' | sudo -u myuser zip -# -9 - ', 'r');
$bufsize = 1024;
$buff = '';
while( !feof($fp) )
{
$buff = fread($fp, $bufsize);
echo $buff;
}
pclose($fp);
}
else
{
echo("<p>Dates have to be different in order for the download to start.</p>");
}
}
else
{
echo("<p>Error: Page called without submit.</p>");
}
?>
</div>
Finally, the jquery part in downloadPage.php, which if I add it doesn't work anymore (which I'd like to learn how to do right, and I mainly learned from the manual of jquery, the last example in the link)
<script>
/* attach a submit handler to the form */
$("#dateRangeID").submit(
function(event)
{
event.preventDefault();
var $form = $(this),
t1 = $form.find("input[name='datefield1']").val(),
t2 = $form.find("input[name='datefield2']").val(),
subm = $form.find("input[name='submit']").val(),
url = $form.attr('action');
var posting = $.post(url, { datefield1: t1, datefield2: t2, submit: subm} );
/* Put the results in a div */
posting.done(function(data) {
var content = $(data).find('#content'); // <--- So this turns out to be wrong. Right is only $(data);
$("#result").empty().append(content);
});
});
</script>
What is wrong in this? Please assist. Thank you.
If you require any additional information, please ask.
Looking at the obvious, you have:
var content = $(data).find('#content');
where, you're trying to find an element with the ID content in one of the following results:
<p>Dates have to be different in order for the download to start.</p>
or
<p>Error: Page called without submit.</p>
Tried to retrieve page url (Jforms EMAIL option) after form submission but form_data:page_url
variable doesn't produce any output at the email.
form_data:page_title doesn't either. There is a Javascript which I believe retrieve URL. I have tried to use Alert(vhref) at the bottom of the script and it return URL pointing to the existing form at the popup window. I need it to be URL of submission result form which is automatically appear (Redirect to->Submitted data 'event') on the screen after form submission. My objective is to have this URL to be included into the email sent. Joomla 3.4.3 , JForms 0.4.4

I have button which in enclosed by <a> tag. When clicked, it executes redirect.php script.
login.php - contains
<input type = "button" id = "loginButton2" class = "btn btn-primary" value = "Login | Twitter " style = "left:650px; margin-top: -32px; position:relative"/>
redirect.php contains twitter authentication code. If authenticated successfully then gives id and name. I want to fetch these both value in index.php
Using ob_start(); I can receive values from php script to JS function via json.
But I am confused about how to manage the code in index.php to execute script on button click and receiving these two value also.
redirect.php
<?php
session_start();
require_once('twitteroauth/twitteroauth.php');
require_once('config.php');
if (empty($_SESSION['access_token']) || empty($_SESSION['access_token']['oauth_token']) || empty($_SESSION['access_token']['oauth_token_secret'])) {
header('Location: ./clearsessions.php');
}
$access_token = $_SESSION['access_token'];
$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $access_token['oauth_token'], $access_token['oauth_token_secret']);
$content = $connection->get('account/verify_credentials');
$twitteruser = $content->{'screen_name'};
$notweets = 5;
$tweets = $connection->get("https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=".$twitteruser."&count=".$notweets);
$id = $content->{'id'};
$name = $content->{'name'};
?>
Please let me know if you need further explaination.
Bottomline:
Rather executing redirect.php script on link click, I want it to execute via function on button click event.
Getting id and name from redirect.php to index.php after redirect script executed
I already have session_start() to manage the twitter session. So dont want to mess up using mutiple session if not necessary ..
UPDATE after david's answer
<body>
<input type="button" value="Run somePHPfile.php" id = "b1" />
<script>
$('#b1').click(function () {
window.location.href = 'redirect.php';
$.get('index.php', function(data) { //If I put this out side click then it gives undefined value for name and id before redirect.php gets executed
// data.id is the id
var id= data.id;
var name = data.name;
alert(name);
});
});
</script>
</body>
Apologize to say:
On button click redirect.php script executed. redirect.php includes other files, which finally reach to index.php. And index.php returns name and id.
So is this enough to manage it : $.get('index.php', function(data) { ... }
To bind to a click event of an HTML button, you would use JavaScript. Since you tagged the question with jQuery, I'll assume its use. The event handler would look something like this:
$('#loginButton2').click(function () {
window.location.href = 'redirect.php';
});
Note: This simulates an anchor click effectively. If you instead want to more closely resemble an HTTP redirect, you might want to use this instead:
window.location.replace('redirect.php');
As for the id and name values, how exactly does this flow return the user to index.php in the first place? Your redirect.php has, well, a redirect (though not all code paths result in that) so it kind of assumes non-AJAX interaction. (I think XHR follows redirects sometimes, but the behavior is different from one browser to another.)
If the redirect isn't terribly important and you just want to make an AJAX call to redirect.php, then you can do that with a simple AJAX request:
$.get('redirect.php');
In order to get those values back to the page, they'll need to be emitted from redirect.php. Something like this:
echo json_encode((object) array('id' => $id, 'name' => $name));
Then in the client-side code you would have those values available in the AJAX callback:
$.get('redirect.php', function(data) {
// data.id is the id
// data.name is the name
// use these values client-side however you need
});
<script>
$("#loginButton2").on('click',function(){
window.location.href="redirect.php";
});
</script>
and in redirect.php file
$_SESSION['id']=$id ;
$_SESSION['name']=$name;
and also
<input type = "button" id = "loginButton2" class = "btn btn-primary" value = "Login | Twitter " style = "left:650px; margin-top: -32px; position:relative"/>
to
<input type = "button" id = "loginButton2" class = "btn btn-primary" value = "Login | Twitter " style = "left:650px; margin-top: -32px; position:relative"/>
