Captcha works with no problem, but I have no idea why it's not generating a new code to dislay? I've looked into the documents but could find something that could solve my problem.
Is there something here that I'm missing. thanks.
public function actions()
{
return array(
'captcha'=>array(
'class'=>'CCaptchaAction',
'backColor'=>0xFFFFFF,
),
);
}
my view file:
<?php echo $form->labelEx($model,'verifyCode'); ?>
<?php $this->widget('CCaptcha'); ?>
<?php echo $form->textField($model,'verifyCode'); ?>
<?php echo $form->error($model,'verifyCode'); ?>
This is a known bug, that would most likely be fixed in Yii2.
On the Yii forums, user Black suggests:
My solution was to remove the session key on my controller action on get. Be careful not to remove it in any other place because it will probably fail on server validation.
$session = Yii::app()->session;
$prefixLen = strlen(CCaptchaAction::SESSION_VAR_PREFIX);
foreach($session->keys as $key)
{
if(strncmp(CCaptchaAction::SESSION_VAR_PREFIX, $key, $prefixLen) == 0)
$session->remove($key);
}
Another way to workaround would be to use JavaScript to click on the refresh link on every page load as mentioned by Soph:
$(function() {
$('#yw0_button').click();
});

I am a newbie working on a screen which has a conditional button which should appear only if $step==2. In this case, the button is shown and on click, redirects me to another page within my project. However, the url to which it should redirect me is not fixed, but has a parameter within it. I am having trouble getting the onclick to work!
I have tried defining a $path variable in which I store the relocation string. I do this in the following way:
<?php $path = '"window.location=\'{{ url("/location/'.$location->id.'/description") }}\'"'?>
When I echo this $path, I get exactly the string I need, which is:
"window.location='{{ url("/location/2/description") }}'"
(Note: The $location->id in my test case is 2)
However, I then try using this $path for the onclick of the button and it's not working! Here is the whole thing:
<?php if ($step == 2) : ?>
<?php $path = '"window.location=\'{{ url("/location/'.$location->id.'/description") }}\'"'?>
<button class="button_s_red" onclick=<?php echo $path; ?>>{{ trans('setup_process.STEP2_Button') }}</button>
<?php endif; ?>
When I inspect this button in chrome, it seems that on the onclick, the / character is not getting through. But this is odd since when I echo the $path I do get this character, and / doesn't seem to be an escape character from what I've googled.
I've tried pretty much everything and googled every possible help but can't seem to make it work! Thanks in advance for your help!
id.'/description") }}\'"'?> >{{
trans('setup_process.STEP2_Button') }}
I think u must use " in Your code like this.
<?php if ($step == 2) : ?>
<?php $path = '"window.location=\'{{ url("/location/'.$location->id.'/description") }}\'"'?>
<button class="button_s_red" onclick=("<?php echo $path; ?>")>{{ trans('setup_process.STEP2_Button') }}</button>
<?php endif; ?>
Okay, here's something that may seem rather trivial, but it's been giving me a headache, and I must have some sort of mental block now.
I want to pass a SESSION variable into JS, and then ultimately onto another page... It's only the first part that I'm worried about for now, because I can't even get a good "alert". The variable is blank... "the page at xxxxx says ____", even though the username shows up in the HTML span tag.
So, here's the applicable code on my page.
EDIT - For those asking why I would do this, I read it on (this) post...
EDIT: Solved. The method to do this is best done with:
var player = "<?php echo $_SESSION['username']; ?>";
Didn't need jQuery or other code. It is simple and direct, and shame on me for just sticking with one proposed solution from the other post.
In answer to some other questions: I did already have start session() at the top of the file. The script was after the HTML/PHP code. ***
... HTML stuff...
You are <span id='username'><?PHP echo $_SESSION['username']?></span></div>
...more HTML...
<script>
function rollpublic()
{
... some declarations...
var player = document.getElementById("username").innerHTML;
alert (player);
more JS }
</script>
Edit
Sidenote: One reason which may be the cause of your session name not appearing, may be because session_start(); is not present in your pages, nor is there any mention of it in your posted code.
Without seeing FULL code, is hard to pinpoint it.
However, here is a successful test that I performed using the following codes: (page 1 & page 2)
Page 1:
<?php
session_start();
$_SESSION['username'] = "USERNAME";
?>
Check session name
Page 2: (sessions_check.php) which will echo and alert the session name.
<?php
session_start();
?>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script>
$(document).ready(function(){
var player = "<?php echo $_SESSION['username']; ?>";
alert (player);
});
</script>
You are <span id='username'><?PHP echo $_SESSION['username']?></span></div>
Appearing in HTML source: var player = "USERNAME";
and You are <span id='username'>USERNAME</span></div>
N.B.: session_start(); needs to be inside all of the pages using sessions in order for this to work properly.
(Original answer) This worked for me:
<?php
session_start();
$_SESSION['username'] = "USERNAME";
?>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script>
$(document).ready(function(){
var player = "<?php echo $_SESSION['username']; ?>";
alert (player);
});
</script>
You are <span id='username'><?PHP echo $_SESSION['username']?></span></div>
You may call session by ajax:
function getSession(){
var session;
$.get('someUrlThatReturnSession', function(sessionData) {
session = sessionData;
});
return session;
}
You can assign SESSION variable to javascrip variable..
<script>
function myFunction(){
var a = <?php echo $_SESSION['var'] ?>;
alert(a);
}
</script>
If you need more help let me know..
If you're using Angular JS, you can use this approach. (Provide the PHP var to the ng-init param of a hidden input)
Hi I am creating a website with a login section this is working I am using HTML and PHP. What I am trying to do is one of my pages has a html button I want this to be disabled for certain users. at the moment this is what I have got.
this is the part that I use for the login details.
<?php
session_start();
$_SESSION["username"];
$_SESSION["password"];
$_SESSION["access"];
?>
I have got if statments that I am currently using which are
if($_SESSION["access"] == "Administrator"){
echo $Admin;
}
what I am trying to do is call a javascript function within a PHP if statement what i have got so far is
<?php
if($_SESSION["access"] == "Consumer")
{
echo '<script type="text/javascript">
Disable();
</script>';
}
if($_SESSION["access"] == "Administrator")
{
echo '<script type="text/javascript">
Enable();
</script>';
}
?>
the javascript functions that i am trying to call are
<script type="text/javascript">
function Enable() {
SubmitButton.disabled = false;
}
function Disable() {
SubmitButton.disabled = true;
}
</script>
I have also tryed
if($_SESSION["access"] == "Consumer")
{
echo "<script> Disable(); </script>";
}
Im just wondering if I have typed something in wrong or if I have forgotten to put something in.
any help would be much appreciated.
Looking at your code you have couple of issues:
Mixing your PHP logic and pure HTML is (usually) not a good idea.
Instead I would suggest you move your access checking logic fully on the server side and display the button accordingly (disabled or enabled) based on the user's access.
Example:
<?php if($_SESSION['access']): // Only show the button for users with access ?>
<button type="submit" value="Submit" <?php echo ($_SESSION['access'] != 'Administrator' ? 'disabled' : ''); // Button disabled for everyone but administrators ?> />
<?php endif; ?>
And let me point out the obvious (as mentioned by the other answers), that's not 100% bulletproof. The user can still manually submit the button even if he is not an administrator by editing the page's HTML on the fly. That's just a UI fix. The real check should be done on the server side once the button is submitted (e.g. is the user logged in, does he have a cookie on his computer that identifies him as an administrator, does he have a session cookie set, etc).
Calling JS in random places, e.g. in the header can have unexpected consequences.
You better wait for the page to be loaded fully before calling any JS functions. You can do that via jQuery easily, but make sure you include the jQuery library before that in your header like so.
Afterwards you can call any JS after the page is loaded by placing them within the following block:
$(function(){
// Place your JS calls here, e.g. call to Enable()
});
String concatenation in PHP is done with a dot . and strings can be multiline
This code which you used is just plain wrong.
echo '<script type="text/javascript">'
, 'Enable();'
, '</script>';
You should use something like:
echo '<script type="text/javascript">'
.'Enable();'
. '</script>';
or better:
echo '<script type="text/javascript">
Enable();
</script>';
PHP doesn't use , sign for joining. Use ..
But otherwise it should work, except that you should define SubmitButton in advance of using it.
<?php
echo "<script type='text/javascript'>";
// if the id of your element is "submitButton"
echo "var submitButton = document.getElementById('submitButton');";
echo " function disable(){ submitButton.disabled=true; }";
echo "</script>";
?>
After that you can use it as you did..
<script type='text/javascript'>
disable();
</script>
Just be advised that denying access to some elements/functionality on your webpage with JavaScript alone is not a good practice - JavaScript is executed locally on the user's computer and therefore the user can modify it to gain an advantage.
Well, the problem may be that you're trying to call the javascript function before the HTML is ready (or finally rendered), so the browser, when executes the function doesn't find the button.
You could solve this placing your javascript code at the end of your page, or using jQuery and doing:
$(document).ready(function() {
<%php if ($_SESSION['access'] == 'xxxxx') {%>
Enable();
<%php } else { %>
Disable();
<%php } %>
});
Anyway, ALWAYS check user permissions on the server side, because someone could enable the button using Firebug or something else...
I'm using easyModal to create modal windows in my web. Saw that they have callback onClose and I want use php code on close is it possible, if yes How to do that? I want to unset some values from sessions (don't have much experience in javascript, jquery or ajax)
This is my code:
<div id="ebox">
<?php
echo $_SESSION['unameE'];
echo $_SESSION['pwordE'];
echo $_SESSION['emailE'];
?>
</div>
$(function() {
$('#ebox').easyModal( {
autoOpen:<?php echo $error; ?>
onClose:???
});
});
Or maybe there is another solution that unsets values from session after displaying it once?
on your script you should have :
onClose: function(){
$("#ebox").html(' ') ;
$.post("remove-session.php");
}
and then on the page "remove-session.php" you can do all sort of stuff with your session:
<?php
unset($_SESSION['unameE']);
//...
//or even
session_destroy();
?>
I am trying to update the $_SESSION['state'] whenever the user clicks on the anchor tag by firing the onclick event. The variable $state_names_array as all the names of the states of a specific country. But problem is that no matter whichever of the anchor tag I click on, the $_SESSION['state'] is always getting updated by the last element of the $state_names_array.
<?php
foreach($state_names_array as $value){
$temp = '<?php $_SESSION["state"]=$value;?>';
?>
<?php echo $value ?><br>
<?php
}
?>
I will not code whole code, I will just show you an example, how to do it:
<?php
foreach ($state_names_array as $value) {
echo ''.$value.'<br>';
}
?>
Then you will have javascript function change_value:
here you will send ajax call to some PHP file, where you will process $_SESSION["state"]=$value;
Also you didnt say, what you want after anchor is clicked, because you will be able to access new $_SESSION["state"] only after refreshing your site...
Also maybe you just want to redirect to index.php, after clicking on some anchor, and that will be enough for you, then just use value as $_GET parameter, f.e.:
<?php
foreach ($state_names_array as $value) {
echo ''.$value.'<br>';
}
?>
and add to you index.php file this lines:
if (isset($_GET['new_value'])) {
$_SESSION["state"] = $_GET['new_value'];
}
