Confirmation popup Box according to a condition on submit button

I am using Drupal 7. In my list I have 2000 subscribers. Now I want a confirmation box before executing the form. The only issue is If I have more than 20 users I want the confirmation form to ask the question" Do you want to continue with 20 users' If the answer is yes, then perform some php operation on it else go to the main page.
function player_operation_display_form_submit($form, &$form_state)
{
if($total_players > 20){
echo '<script type="text/JavaScript">
var a = confirm("Do you want to continue with more than 20 users");
if(a){ //performing some operation
$operation[] = array('Assign_goals', array($records_value,
$records_key, $assign_username));
}
else{
drupal_goto('exit_operation');
die();
}
</script>';
}
Now I understand that $operation[] and exit_operation are my php functions and wont execute in my js file. I just want to know how to execute these functions.

You can do this on js file just before submit the form.
<script>
$(function() {
var total_players = <?php echo $total_players;?>;
$('#form').submit(function() {
if(total_players > 20){
if (confirm("Do you want to continue with more than 20 users?")){
$('form').submit();
}else{
return false;
}
}
});
});
</script>
For more appropriate solution please share your html form code and java script code.

window.location.reload(true) reloads page but page needs refreshing to show changes

Have a function that makes a change to taxonomy term via AJAX. This works great, except the content remains unchanged on window.location.reload(true) even though the change has been made. See the code and GIF below to understand.
This is an example that adds the button and reloads page on click
if ( 'publish' === $post->post_status && $post->post_type === 'campaigns' ) {
$text = (in_category( 'live') ? 'Activate' : 'Activate');
echo '<li>' . $text . '</li>';
}
So, is there another way that I can reload the page onClick that may help? Also, the post modified date is not updating, yet changes have been made to the post.
Thanks in advance for your help
EDIT -
I have already tried
location.href = location.href; and
document.location.reload();
ADDITIONAL INFO -
Function
add_action('wp_ajax_toggle_live', function(){
// Check ID is specified
if ( empty($_REQUEST['post']) ) {
die( __('No post ID specified.') );
}
// Load post
$post_id = (int) $_REQUEST['post'];
$post = get_post($post_id);
if (!$post) {
die( __('You attempted to edit an item that doesn&#8217;t exist. Perhaps it was deleted?') );
}
// Check permissions
$post_type_object = get_post_type_object($post->post_type);
if ( !current_user_can($post_type_object->cap->edit_post, $post_id) ) {
die( __('You are not allowed to edit this item.') );
}
// Load current categories
$terms = wp_get_post_terms($post_id, 'campaign_action', array('fields' => 'ids'));
// Add/remove Starred category
$live = get_term_by( 'live', 'campaign_action' );
$index = array_search($live, $terms);
if ($_REQUEST['value']) {
if ($index === false) {
$terms[] = $live;
}
} else {
if ($index !== false) {
unset($terms[$index]);
}
}
wp_set_object_terms( $post_id, 'live', 'campaign_action' );
die('1');
});
JS
function toggleLive(caller, post_id)
{
var $ = jQuery;
var $caller = $(caller);
var waitText = ". . .";
var liveText = ". . .";
var deactivateText = ". . .";
// Check there's no request in progress
if ($caller.text() == waitText) {
return false;
}
// Get the new value to set to
var value = ($caller.text() == liveText ? 1 : 0);
// Change the text to indicate waiting, without changing the width of the button
$caller.width($caller.width()).text(waitText);
// Ajax request
var data = {
action: "toggle_live",
post: post_id,
value: value
};
jQuery.post("<?php bloginfo( 'wpurl' ); ?>/wp-admin/admin-ajax.php", data, function(response)
{
if (response == "1") {
// Success
if (value) {
$caller.text(deactivateText);
} else {
$caller.text(liveText);
}
} else {
// Error
alert("Error: " + response);
// Reset the text
if (value) {
$caller.text(deactivateText);
} else {
$caller.text(liveText);
}
}
// Reset the width
$caller.width("auto");
});
// Prevent the link click happening
return false;
}
IT WORKS RIGHT ON PAGE THAT ISN'T SINGULAR

Is toggleLive the function that makes the AJAX request? You are calling reload immediately on click before changes are reflected on the backend. If you are using Jquery include your reload code in the complete callback function that indicates completion of your AJAX request.

Try using Live Query plug-in in jquery instead of live .

I was able to achieve this by setting return trueOrFalse(bool); in the JS and adding the permalink for the page into <a href=""> within the function.
I believe #cdoshi was correct in their answer, yet I was unable to achieve this. I am sure that a little further exploration would make this possible, yet my fix achieved what I wanted with little change to my code.

Form submited two times (ajax with jquery)

i have a simple form: when i submit it without javascript/jquery, it works fine, i have only one insertion in my data base, everything works fine.
I wrote some jquery to have result in ajax above the input button, red message if there was an error, green if the insertion was done successfully. I also display a small gif loader.
I don't understand why when i use this jquery, two loaders appear at the same time and two insertions are done in my database.
I reapeat that when i comment the javascript, it works fine, i'm totally sure that my php is ok.
$('#addCtg').submit(function () {
var action = $(this).attr('action');
var name = $('#name').val() ;
$('.messages').slideUp('800', function() {
$('#addCtg input[type="submit"]').hide().after('<img src="spin.gif" class="loader">');
$.post(action, {
name: name
}, function (data) {
$('.messages').html(data);
$('.messages').slideDown('slow');
$('.loader').fadeOut();
$('#addCtg input[type="submit"]').fadeIn();
});
});
return false;
});
I really don't understand why it doesn't work, because i use the 'return false' to change the basic behaviour of the submit button
Basic php just in case:
<?php
require_once('Category.class.php');
if (isset($_POST['name'])) {
$name = $_POST['name'] ;
if ($name == "") {
echo '<div class="error">You have to find a name for your category !</div>' ;
exit();
} else {
Category::addCategory($name) ;
echo '<div class="succes">Succes :) !</div>' ;
exit();
}
} else {
echo '<div class="error">An error has occur: name not set !</div>';
exit();
}
And finnaly my function in php to add in the database, basic stuff
public static function addCategory($name) {
$request = myPDO::getInstance()->prepare(<<<SQL
INSERT INTO category (idCtg, name)
VALUES (NULL, :name)
SQL
);
$r = $request->execute(array(':name' => $name));
if ($r) {
return true ;
} else {
return false ;
}
}
I rarely ask for help, but this time i'm really stuck, Thank you in advance

You're calling: $('.messages') - I bet you have 2 elements with the class messages. Then they will both post to your server.

One possible reason could be because you are using button or submit to post ajax request.
Try this,
$('#addCtg').submit(function (e) {
e.preventDefault();
var action = $(this).attr('action');
var name = $('#name').val() ;
$('.messages').slideUp('800', function() {
$('#addCtg input[type="submit"]').hide().after('<img src="spin.gif" class="loader">');
$.post(action, {
name: name
}, function (data) {
$('.messages').html(data);
$('.messages').slideDown('slow');
$('.loader').fadeOut();
$('#addCtg input[type="submit"]').fadeIn();
});
});
return false;
});

Not allowing a user to move forward to logging in until given access [duplicate]

This question already exists:
Blocking a user from logging in with a certain permission level and then an alert displaying to let them know why
Closed 7 years ago.
I am trying to figure out how to deny a user access from signing in to my site unless they have been approved. I am making my site private to only those I allow to join. Anyone can register, but once they do they are given a permission/group level of 1 or 'bench'. Once I accept the user and change the permission level, then they are able to login.
As of now, I am stopping the level/group 1 users with a redirect back to the index page(where they sign in at). However, I want to not allow them to move forward to the next page at all. The reason being is I want to display some sort of pop up alert displaying a message that I created.
I'm not sure if I can do this with validation or the way I am trying to do it. I added on to my login code and am attempting to put my permission code I had on the signed in page to try to stop it from the start. Basically, in an attempt that if the user tries to log in, the script dies once it sees that the permission level is at the group 'bench'. Then a pop alert displays saying why.
I'm not having much success with it. My group/permission levels have a name and ID. I have tried putting both in this single quotatiob's like 'bench' and '1', but I get the same error with both.
Fatal error: Call to a member function hasPermission() on a non-object in /home4/pfarley1/public_html/example.com/index.php on line 12
I'm trying to log them in like this...
<?php
if(Input::exists()) {
if(Token::check(Input::get('token'))) {
$validate = new Validate();
$validation = $validate->check($_POST, array(
'username' => array('required' => true),
'password' => array('required' => true)
));
// added this line in
if($user->hasPermission('1')) {
die($permissionError);}
if($validation->passed()) {
$user = new User();
$remember = (Input::get('remember') === 'on') ? true : false;
$login = $user->login(Input::get('username'), Input::get('password'), $remember);
if($login) {
Redirect::to('userIndex.php');
} else {
$tryagain = '<span class="signinpanel">' . "The information you entered did not match our records." . '</span>';
}
} else {
foreach($validation->errors() as $error) {
echo $error, '<br>';
}
}
}
}
?>
My permission code for users..
public function hasPermission($key) {
$group = $this->_db->get('groups', array('id', '=', $this->data()->group));
if($group->count()) {
$permissions = json_decode($group->first()->permissions, true);
if($permissions[$key] == true) {
return true;
}
}
return false;
}
What am I doing wrong this this or is there a better way to do this?
Edit:
The last question wasn't specific enough, so I added info and there has been modification to the code in how I was trying to do this.

What is $user on line 12?
if($user->hasPermission('1')) {
Error message is pretty explicit.

Ajax validation in form update in yii

I have a form for both creation and editing some fields.I am using Ajax validation for that before submitting the form like
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'candidates-profiles-form',
'enableAjaxValidation'=>true,
'enableClientValidation'=>true,
'clientOptions'=>array(
'validateOnSubmit'=>true,
'validateOnChange'=>false,
'beforeValidate'=>"js:function(form) {
if((form.data('submitObject')[0].id ) == 'cancel'){
alert('cancalclicked');
this.validateOnSubmit = false;
this.validateOnChange = false;
this.beforeValidate = ''; // the problem is caused by this line
form.submit();
return false;
}
else{
alert('submitclicked');
return true;
}
}",
'afterValidate'=>"js:function(form, data, hasError) {
if(hasError) {
alert('We have detected some input errors and has not saved your data. Please click Ok to correct them.');
return false;
}
else {
if(confirm('We have validated your input and we are ready to save your data. Please click Ok to save or Cancel to return to input.'))
return true;
else
return false;
}
}",)
)); ?>
After creation it is perfectly coming in afterValidate function and works fine.But after editing it is not all coming in afterValidate. But it is coming in beforeValidate and submitting the form with out reaching afterValidate .

Make sure you have $this->performAjaxValidation($model); in your controller for that action.
