How do I retrieve the contents of a simpleXMLElement variable from a php file with jquery?
Send the return value of SimpleXMLElement::asXML()
Self-contained example:
<?php
if ( isset($_GET['foo']) ) {
$foo = new SimpleXMLElement('<foo />');
$foo->bar->baz[] = date('Y-m-d H:i:s');
$foo->bar->baz[] = rand(1,100)." la la la";
header('Content-type: application/xml; charset=utf-8');
echo $foo->asXML();
die;
}

I have a script code to upload photos on imgur using AJAX. But I can not hide the Client-ID of the public.
I think I need to use PHP to do that use this code:
<?php $idClient = "abc12abc12abc";
echo $idClient ;
?>
But it turned Client-ID is still visible when in view its source code.
Here's the full code:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Imgur Upload Test</title>
<style>
#image_preview, #image_preview_2 {
max-width: 200px;
}
</style>
</head>
<body>
<h1>Imgur Upload Test</h1>
<input type="file" id="image_selector" />
<div id="image_preview"></div>
<h2>Image On Imgur:</h2>
<div id="image_preview_2"></div>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>
$("#image_selector").change(function() {
var reader = new FileReader();
reader.onload = function(e) {
var data = e.target.result.substr(e.target.result.indexOf(",") + 1, e.target.result.length);
$("#image_preview").html("<img src='" + e.target.result + "' />");
$.ajax({
url: 'https://api.imgur.com/3/image',
headers: {
'Authorization': 'Client-ID <?php $idClient = "abc12abc12abc";
echo $idClient ;?>'
},
type: 'POST',
data: {
'image': data,
'type': 'base64'
},
success: function(response) {
$("#image_preview_2").html("<img src='" + response.data.link + "' />");
}, error: function() {
alert("Error while uploading...");
}
});
};
reader.readAsDataURL(this.files[0]);
});
</script>
</body>
</html>
What's the solution?
How i can check $enjaz_youm every second in the index page for my system
<?
if($enjaz_youm == 80) {
echo "<script>";
echo "alert('This is an alert from JavaScript!');";
echo "</script>";
}
?>
Thanks
You can try this.
<?php
if ($_POST['action']=='enjaz_youm') {
//do your checks here
if ($enjaz_youm==80) echo '1';
die();
}
?>

I want to save the image generated on the server. For this I use iframe, but the File Save dialog does not appear after the click. What am I doing wrong?
index.php
<html>
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script>
$(document).ready(function() {
$('#onv-save-button').click( function() {
$.ajax ({
url: "/ajax.php",
type: "POST",
success: function(data) {
$('#downloadFrame').attr('src' , data);
}
});
});
});
</script>
</head>
<body>
<iframe src="" id="downloadFrame" ></iframe>
<button id="onv-save-button">Go!</button>
</body>
</html>
ajax.php
<?
// Some actions to generate image
echo "1.png" ;
?>
I did. Here is the answer to the question.
index.php
<html>
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script>
$(document).ready(function() {
$('#onv-save-button').click( function() {
$.ajax ({
url: "/ajax.php",
type: "POST",
success: function(data) {
alert(data);
$('#downloadFrame').attr('src' , "download.php?file=" + data);
}
});
});
});
</script>
</head>
<body>
<iframe src="" id="downloadFrame" ></iframe>
<button id="onv-save-button">Go!</button>
</body>
</html>
ajax.php
<?
echo $_SERVER["DOCUMENT_ROOT"]."/1.png";
?>
download.php
<?php
$content = file_get_contents($_REQUEST['file']);
header('Content-Description: File Transfer');
header("Cache-Control: ");
header("Pragma: ");
header("Content-Disposition: attachment; filename=\"".basename($_REQUEST['file'])."\"");
ob_end_clean();
ob_start();
echo $content;
ob_end_flush();
exit();
?>
I read all other question but nothing really helped.
I have one page with display and other php files supporting it but when I pass a POST and make a $_SESSION['view'] out of it with another POST request but not same one the $_SESSION['view'] is gone.
So in practic when user change view from four months (default) to one month and then click NEXT view gets back to four months.
Display Page
<?php
session_start();
$dateb = (new DateTime())->getTimestamp();
$_SESSION['usrdate'] = $dateb;
?>

This script is supposed to run a jQuery Ajax script every second, it is supposed to fetch all newer posts then put them on top of the original ones. But at the moment nothing is happening, it loads the initial posts but nothing else. Firebug console is reporting no errors, or no Ajax requests being sent at all. Can you see anything wrong with this script at all that could cause this? Thanks :)

Some of the code in the beginning looks wrong. This should work. It will call the oneSecondFunction every second:
$(document).ready(function() {
setInterval(oneSecondFunction, 1000);
function oneSecondFunction() {
//console.log('run oneSecondFunction');
var ID = $(this).attr("id");
if(ID) {
$("#more"+ID).html('<img src="moreajax.gif" />');
$.ajax({ type: "POST", url: "ajax_more.php", data: "lastmsg="+ ID, cache: false,
success: function(html){
$("ol#updates").prepend(html);
$("#more"+ID).remove();
}
});
} else {
} return false; };
});
i quoted out the section where it gets the id, because 'this' wasn't referring to anything.
<script type="text/javascript">
$(function() {
setInterval(oneSecondFunction, 1000);
});
function oneSecondFunction() {
//var ID = $(this).attr("id");
var ID = '1';
if(ID){
$("#more"+ID).html('<img src="moreajax.gif" />');
$.ajax({
type: "POST",
url: "ajax_more.php",
data: "lastmsg="+ ID,
cache: false,
success: function(html){
$("ol#updates").prepend(html);
$("#more"+ID).remove();
}
});
}
return false;
}
</script>
