How to call a function onClick of a directory - php
i'm trying to make a file browser and i'm trying to find how to call a function when the user clicks on a directory. For starting i tried to use onClick inside a href on the class part (right before FUNCTION folderSize) having us a goal to open the path inside testDir if i click on any of the files or directories on the list but it does nothing. I'm searching for some hours now it but i can't find the solution. If someone could help i would be greatfull.
Here is the index.php:

Please Notice, that this code is not suitable for public productive use. It's good enough to learn with it.
The HTML-Part:
Directory-Name
The jQuery (Js) Part:
function call_php_function(php_function, anyattribut) {
$.post("functions.php", ("call_function": php_function, "attribute_name": anyattribut), function (data) {
// Data is what you get from the echo in the PHP-Script below
alert(data); // Outputs "hello"
}
}
The PHP-Part:
function any_php_function($attribut) {
echo "hello";
}
$allowed_funcs = array("any_php_function", "any_other_function");
if (in_array($_POST["call_function"], $allowed_funcs))
call_user_func($_POST["attribute_name"]);
This code is enough for your purposes:
HTML-Part:
directory-name
jQuery-Part:
function call_php_function(directory) {
$.post("your_file.php", ("dir": directory), function(data){
alert(data); // Will output, whatever your starter-functions outputs
});
}
PHP-Part
if (isset($_POST["dir"]) && !empty($_POST["dir"])) {
starter($_POST["dir"]);

PHP Switch Case not ending statement after "break;"
In following function if the input is blue then it is giving result as: "header content goes here Your favorite color is blue!" whereas it is supposed to give- "Your favorite color is blue!", please help me correcting it. If input is red then it is ending statement here as: "header content goes here" which is correct.
Please forgive me if I am asking silly question as I am new to PHP and I don't know if it is ok or not to use function as variable in switch case.
test1.php
<?php
function header2() { ?>
header content goes here
<?php }
$good =header2();
$Input2 = $_POST['input'];
switch ($Input2) {
case "red":
echo $good;
break;
case "blue":
echo "Your favorite color is blue!";
break;
case "green":
echo "Your favorite color is green!";
break;
default:
echo "Your favorite color is neither red, blue, nor green!";
}
?>
main.js
$('[id=stringone]').click(function(){
var string =$('[id=stringotherone]').val();
$.post('test1.php',{input: string}, function(data){
$('[id=stringotherthanone]').text(data);
});
});
test.php
<! doctype html>
<html lang="en">
<head>
<link rel="stylesheet" href="css/hwcb.css">
</head>
<body>
<input type="button" value="Go" id="stringone">
<input type="text" id="stringotherone"/>
<p><div id="stringotherthanone"></div></p>
<script src="jquery.js"></script>
<script src="js/css.js"></script>
<script src="main.js"></script>
</body>
</html>
You need to return in the function otherwise it outputs when the function is called. Example: https://3v4l.org/1Ptml vs. https://3v4l.org/ug778 $good =header2(); is outputting the header content goes here, not the echo $good; in the switch. That actually does nothing because that variable is empty.
Change
<?php
function header2() { ?>
header content goes here
<?php }
to
<?php
function header2() {
return 'header content goes here';
}
Multi language with php .po (Poedit) [duplicate]
on my website, the user has several options such as language, date and region. when the user clicks anyone of those all is fine, the website adapts to the specific choices, but when they go to another page they loose all their choices, it would be nice if i found a way to keep them for their entire visit or perhaps 24hours.
example: bob goes onto my website, under the region setting, he clicks UK and as a result the website adapts and shows him a UK flag as a result. However, he when he goes to the next page he looses the flag and his region setting and has to choose his region setting all over again.
This is what I want to fix. I will post the whole code up in case this may help:

This may be doable in cookies/sessions or something similar but i dnt know how i could incorporate cookies/session into this with the way i have coded it.
Any other suggestions other than cookies or sessions are welcome.
Any help greatly appreciated.
VERY IMPORTANT UPDATE
*After the suggestions below i tried this code:*
<?php
session_start(); //put this at the top of your script on all pages that need to remember
if(isset($_POST['languages']))
{
$_SESSION['languages'] = $_POST['languages'];

WHICH DIDNT WORK. ANY reasons why, seem to have done everything people have told me?**
The session can be used at this situation. You can assign these values in the session variable and can access on all the pages of application. $_SESSION['somevar']='someval';
You should take a serious look at using gettext for manageable localization support. Instead of doing conditionals for every piece of your page, you'll simply call a function like <?php _('Welcome!') ?> and it will be automatically translated according to your language setting.

Sessions or Cookies are definitely the best way to do it:
The thing is that you have to have a way to connect it with the user.
Technically you could store it in a database and either store a cookie on the user's computer that says which database entry to read or even store the user's ip and relate it to the user that way (although that's a pretty unreliable method). But that's all probably an overkill for what you want to do.
Here is how to incorporate sessions into your code:
Posting only one language
For a start lets reformat what you already have.
You have $_POST['languages'] which is actually an array that contains one result.
In that case you may as well make it a string and call it $_POST['language']
You also must remember to post it correctly (in the singular) when the user originally chooses his language.
First off you have to start the session at the top of the page:
session_start();
Next you have to save the user's selection to a session variable.
We are going to check if the user has selected a language (from the $_POST variable) and, if yes, assign it to a $_SESSION variable.
if ($_POST['language']) {
$_SESSION['language'] = $_POST['language'];
}
The session variable functions identical to any other variable, but it will carry on from page to page until the session ends.
Now we are going to check what the language is
This is pretty simple. In your example you checked what the language was by finding what the user had 'posted':
isset($_POST['languages'])
In our new code, we are going to check the session variable, which we have just saved:
$_SESSION['language']
Choosing the right language
No need to make $_POST['languages'] an array and then use a foreach to loop through it.
A simpler way of doing it would be like this:
switch($_SESSION['language']) {
case "german": //do german suff
case "english": //do english suff
etc...
}
Additionally, you first checked if the session tag was empty and then put a value if it wasn't.
You can skip that step and instead put inside the switch() { } at the end, after all the cases:
default: //do default language stuff
As a session:
session_start(); //put this at the top of your script on all pages that need to remember
if(isset($_POST['languages']))
{
$_SESSION['languages'] = $_POST['languages'];
}
Then change:
foreach ($_POST['languages'] as $language) {
to
foreach ($_SESSION['languages'] as $language) {
As a cookie:
if(isset($_POST['languages']))
{
setcookie('language', $_POST['languages'], 7776000) //sets cookie for 90 days, or 7776000 seconds
}
and change
foreach ($_POST['languages'] as $language) {
to
foreach ($_COOKIE['languages'] as $language) {
I believe this answer is complete... do you intend to support multiple languages?
DEMO + SOURCE: https://so.lucafilosofi.com/remembering-users-selection-from-one-page-to-the-next/
<?php
session_start();
if (isset($_GET['lang'])) {
$_SESSION['lang'] = $_GET['lang'];
}
if (isset($_SESSION['lang'])) {
define(LANGUAGE, $_SESSION['lang']);
}
else {
define(LANGUAGE, 'en_GB');
}
include 'languages/'.LANGUAGE.'.php';
?>
Add the top of the code, write "session_start();" After that, whenever an update is submitted, update the matching $_SESSION array's index (you may choose names such as "region", "language", "lng" - the choice is up to you as long as you are consistent). Then, whenever you are loading a page, load it depending on the value in the $_SESSION array. See also: http://il2.php.net/manual/en/book.session.php
After all related session updates - one main thing is that how you set your $_SESSION variables. It shows that you get it from $_POST, but there is no place in code that actually posts the value. You mention that someone clicks to change the language - is it done via the form submit, or via a URL? Add a dump of $_SESSION variable right after you set the language value, and see if it actually gets set... I have a feeling that you never reach that line of code as you don't have a $_POST variable defined anywhere...
The only problem with the session variable is that the user can't change his setting anymore, if that is what you want! But it should be possible using hidden input variable on each page, too. In fact I'm using hidden input variable all the time and also I compress this variable so it is quite fast and secure and also I'm using ajax.
It is very difficult to read the lengthy example code. Please reduce the size of a non working example. The PHP session code relies on a SESSION ID. There are two ways to transport these ID from web page to web page: POST and GET. But what I can see is, that you support only one, the POST method. In case of GET you must add the SESSION ID variable SID to the URL used for navigation. The details of SESSION ID handling are described in the PHP documentation: Passing the Session ID
Show specific alert, depending on the value of GET in php
Im learning PHP, Html and twitter-bootstrap (v2.3.2). I'm trying to display a message depending on the value received by GET.
I have two alerts in different sections of the site and I want depending on the value received by GET display one or the other. not both.
i.e: http:localhost/test.php?load=lannister, should show the message: "A Lannister always pays his debts". however, the url: http:localhost/test.php?load=stark, should show the message: "you know nothing john snow". But I can not figure how to do this, I need a hand, I thought it could be done with an if-else, but I fail to understand how to do it at all. Any ideas?
Heres the code:
<?php session_start();?>
<!DOCTYPE html>
<html>
<head>
<title>Testing</title>

switch ($load) {

break;
}
?>
<?php
if ($load==='stark'){
echo "<div id=\"alert_message\" class=\"alert alert-error\">
<div id=\"alert_placeholder\" align=\"center\" style=\"color:#FFFFFF;font-size: 0.9em;\">".$message."</div>
</div>";
} else{

}?>
</div>
</body>
</html>
I know it's a silly question, but I've been thinking how to do it for hours without any success. Thanks in advance
You're correct in using a switch statement, but as #true stated in his comment, you should check to ensure the variable is set and not empty.
You could do that in long/short hand:
// long
if(isset($_GET['load']) && !empty($_GET['load'])) {
$load = $_GET['load'];
} else {
$load = null;
}
//short
$load = (isset($_GET['load']) && !empty($_GET['load'])) ? $_GET['load'] : null;
Since you set $load to null if it's not present/empty. You can test like this:
if($load == NULL) {
// message is error because neither stark/lannister selected
} else {
switch($load) {
case "stark":
//do start stuff here
break;
case "lannister":
// do lannister stuff here
break;
}
}
Now for the final part. This block of code:
if ($load==='stark'){
echo "<div id=\"alert_message\" class=\"alert alert-error\">
<div id=\"alert_placeholder\" align=\"center\" style=\"color:#FFFFFF;font-size: 0.9em;\">".$message."</div>
</div>";
}
Is not needed. (The if condition is not needed) As you already do the conditioning work in the switch statement to set the message that will be displayed in the alert box. Meaning you'd just have the echo somewhere in your markup!
echo "<div id=\"alert_message\" class=\"alert alert-error\">
<div id=\"alert_placeholder\" align=\"center\" style=\"color:#FFFFFF;font-size: 0.9em;\">".$message."</div>
</div>";
Try cleaning up the code a small amount to make life easier on you.
<?php if($_GET){
$load = isset($_GET['load']) ? $_GET['load'] : null;
}
if ($load == "stark") {
//ECHO
}
elseif ($load == "lannister") {
//echo
}
else {
//default
}

right now it displays an animated gif while it uploads the images. what i want to do is remove the gif and replace it with a progress bar but i have no clue how to do this and i am on a time schedule. could anyone please tell me how to do this. thanks!
The PHP code for processing the upload does not run until the entire file is uploaded, so it is not possible for you detect how much of the file has been uploaded in that script. Generally you find upload progress bars built into a browser or some "client-side" program like a Flash application that can control that level of transfer. For a strict PHP and Javascript implementation there are some workarounds that are fragile and a lot of work and are not very common (hence why you are asking here). There are some jQuery plugins that exist that can do this http://plugins.jquery.com/uploadfile/.
php image rotation not working
I have a script that creates thumbnails based on an image (using crop_image), which is working CORRECTLY. However, the script should also rotate the image correctly depending on the EXIF information and for some reason it always FAILS when I add that part and I'm not sure why. The code and file paths is exactly the same as the resizing part.
//THE FUNCTION USED BELOW
function correctImageOrientation($rotatedfile) {
if (function_exists('exif_read_data')) {
$exif = exif_read_data($rotatedfile);
if($exif && isset($exif['Orientation'])) {
$orientation = $exif['Orientation'];
if($orientation != 1){
$img = imagecreatefromjpeg($rotatedfile);
$deg = 0;
switch ($orientation) {
case 3:
$deg = 180;
break;
case 6:
$deg = 270;
break;
case 8:
$deg = 90;
break;
}
if ($deg) {
$img = imagerotate($img, $deg, 0);
}
// then rewrite the rotated image back to the disk as $rotatedfile
imagejpeg($img, $rotatedfile, 100);
}
}
}
}
//THIS PART DOES -NOT- WORK
$adirname = session::value('userid');
$rotatedfile = '/home/path/www/uploads/'.$adirname.'/'.$file_name;
correctImageOrientation($rotatedfile);
copy($rotatedfile, '/home/path/www/uploads/'.$adirname.'/'.$file_name);
//THIS PART WORKS -OK-
if(!file_exists('/home/path/www/uplimg/'.$adirname.'/500_resized_'.$file_name)){
$adirname = session::value('userid');
list($width, $height, $type, $attr) = getimagesize('/home/path/www/uploads/'.$adirname.'/'.$file_name);
$prop = $width / $height;
$newheight = round(500 / $prop);
crop_image('/home/path/www/uploads/'.$adirname.'/'.$file_name,'/home/path/www/uploads/'.$adirname.'/500_resized'.$file_name,500,$newheight);
