This is the answer. If you log out the $allowed_forums array, or even just the $forum_id inside the foreach loop, you will see that at least one entry is blank/empty. Danish provided at least 2 ways you could rewrite the code to mitigate this. You also might look into how exactly it is that the array gets built with empty array elements in the first place, and prevent that from happening. There are useful performant array functions like array_filter that can make this quite easy to do. For example: foreach (array_filter($allowed_forums) as $forum_id) { ... etc. } By default, with no callback, array_filter will remove any array elements that are empty or false equivalent, so that would also fix your current issue, although again, it might be better to find the actual source of the empty/erroneous array value in the first place.

You have been provided some plausible theories already. As explained by Psycho, with loosely typed languages like PHP, type coercion is often used in logic statements, where zero is equivalent to false. You have been asked a number of times for some code to look at. Days have now gone by, and still we have no code to analyze. You also have said that you get no errors, but I'm not sure if we can trust that information. A production PHP site is typically set up to not display any errors, and usually to log them to a file instead. Have you verified your configuration, and checked the relevant error file?

Right -- well as I said, yes it looks like there is something different about the login credentials for the database. Typically on Godaddy shared hosting the mysql database is a shared resource, and they should document what you need to use for the host string, as well as being able to set your login/password for a specific database. I would suggest you seek that info from GoDaddy.

I don't use mysqli personally, but according to the manual it returns either an object or false.

There's any number of things that could be problematic but that "error" is specifically a "warning". In general warnings are things you might need to be aware of, but don't rise to the level of an actual runtime error. The line you think is 68 doesn't run a mysqli query, so that is not the source of the problem. Given the offset of the errors it looks like it's the INSERT statement inside the loop that is failing. Other queries to follow that try to truncate the database and insert into the control table also fail. This error tends to be associated with trying to use a mysql connection that isn't open or was open and then closed by erroneous code. Since you left out some code, it's hard to be certain, but an educated guess makes me think that the database connection is failing, since you never check in this line: $connect = new mysqli($servername, $username, $password, $dbname); You should check that with: if (!$connect = new mysqli($servername, $username, $password, $dbname)) { echo "<p>Could not connect to the database</p>"; }

I'm confused. You have 2 workstations both running linux, and you can't find where xampp is in the windows start menu? Personally, I don't understand why you would use xampp under Linux, when it's easy enough (and just better all around) to install the components you want using the distro package manager. Xampp for linux is a poor substitute for that, for a variety of reasons. Furthermore, when you can easily use docker and any of the many docker projects that will easily orchestrate the docker containers for the same components. Laradock and Devilbox are two projects that have been around for a long time, either of which makes it easy to get a docker based lamp stack up and running, with many commonly used components and toolchains that can be added in. Last but not least, linux has the old "which" and "whereis" commands available you can use to find out where programs exist (httpd, php, mysql, etc). This combined with a search of /etc will usually show you where things are, and what configuration files are being used.

Because HTML provides structure not layout. CSS provides layout, and in particular css position has many options for positioning elements in a particular place. Sticky, Fixed and Absolute are all position settings that might accomplish whatever it is that you are trying to do. Without specific examples of html and css you are working with, there isn't much more anyone can do for you.

Your desired format is json. You keep posting the output from a var_dump of a php array. Do you understand the difference between json and a php array, and that var_dump is just a diagnostic tool for seeing what php arrays and objects look like internally? You must json_encode() the data as Barand already instructed. Take the output you get from json_encoding and paste that into a code block for any future discussion please.

The ability to print from a website is a local operating system capability, built into the browser. There is nothing special that PHP can do to help or hinder the process. Javascript can be used to invoke the built-in browser support for printing, but again, printing will always require the user to take action. For example, here is a simple button inside an anchor tag with some javascript. <a href="#" media="all" onclick="window.print();return false;"><button type="button">Print</button></a> You can use media queries in your css to style a page for printing by adding a style section like this: @media print { /* styles here */ } Typically people will hide things like menus, footers, nav, sidebars etc. You also might want to set a margin around the content, since typically printers have that constraint, so you might have something like this: @media print { header, footer { display: none; } } Here is a pretty good sitepoint article that goes into much more detail.

I suppose you could do lookaheads to make sure that the @ is the last character or followed by whitespace. This would leave pre-existing replacements alone. $(document).on('change','#userlist', function(e){ const username = $(this).find('option:selected').val(); let notesInput = $('#notes-input').val(); notesInput = notesInput.replace(/(@((?=$)|(?=\s)))/i, '@'+username); $('#notes-input').val(notesInput); $('#userlist').addClass('d-none'); $('#notes-input').focus(); });

It's actually not funky at all. Without the customization of the session location, php will use the system default, which on a linux server is /tmp.

You did not provide the code that moves the input into the list. It's also not clear whether or not the text should retain the @. The first issue is this line: $('#notes-input').val() = $('#notes-input').replaceWith('/@([a-z0-9_]+)/i', username); Using jquery selector.val() gets the value. So you can't assign something to that. You also have an issue using replaceWith, which replaces an entire element rather than just the value. Another change I've added triggers the substitution on the select list 'change' event rather than the click event. I put in some debug statements so that you can better see what is happening. $(document).on('change','#userlist', function(e){ const username = $(this).find('option:selected').val(); console.log(username); let notesInput = $('#notes-input').val(); console.log(notesInput); notesInput = notesInput.replace(/@([a-z0-9_]+)/i, '@'+username); console.log(notesInput); $('#notes-input').val(notesInput); $('#userlist').addClass('d-none'); $('#notes-input').focus(); });

I don't know what your development platform is, but there are many issues with email deliverability that will be hard to diagnose. For this reason, I highly recommend using a local mail catcher/debugger with one of the best known being Mailhog. Unfortunately mailhog seems to be an abandoned project, so a newer one that is currently maintained is mailpit. Assuming that you have docker installed, you can start mailpit easily using docker run: docker run -d \ --restart unless-stopped \ --name=mailpit \ -p 8025:8025 \ -p 1025:1025 \ axllent/mailpit This will start what looks to client code like an SMTP server available at localhost:1025, and there will be an admin web interface that shows you the emails that are received on port localhost:8025. You would need to change your phpmailer setup slightly for testing, so that you send mail to localhost and port 1025. I don't know if TLS support works or not so you may need to disable the tls settings. I also think it would help you if you studied the concept of dependency injection. For example, whenever you have a method or function that is doing something like this: // Function to send email notification using PHPMailer function sendEmailNotification($recipientEmail, $applicationId, $surname) { // Instantiate PHPMailer $mail = new PHPMailer(true); That should be a sign to you that you probably want to use dependency injection instead. Best practices at this point are to move credentials out of your code base and into .env files or something similar. Having credentials in your code is another vector for security exploitation. If someone gets access to your source code, they have everything they need to connect to your server or in a case like this, send emails to an account. They also make having different environments (dev/test/stage/production) each with different configurations that isolate them from each other. Hopefully you are not developing and testing in production! Most of what you are doing in sendEmailNotification() is setting up PHPMailer. You should move all of that code out into a configuration routine that reads configuration variables from a .env or perhaps a simple php configuration file. Instead of what you are currently doing, you should create and configure your phpmailer object outside the sendEmailNotification function, and pass it as a dependency. // Function to send email notification using PHPMailer function sendEmailNotification(PHPMailer $mail, $recipientEmail, $applicationId, $surname) { You could add a simple function that configures and returns a PHPMailer object, and reads in configuration variables in some other way. There are plenty of libraries out there, to read .ini files, or dotenv etc.

There are a couple of PHP specific commercial addons. The default one isn't very good unfortunately, and you should disable it. I have had good results (as have many other people) using PHP Inteliphense. Inteliphense can be used in basic mode, or you can pay $20 use to get upgraded features. I would start with the free version and see if it is working for you, and then if you like it, consider paying for the extra features. It is very important that you follow the instructions on the page, which has you disable the default php intelisense. Otherwise it will conflict with other php addons. As for xdebug, there isn't one magic way for it to work, because it really depends on how and where you are running php. In the php4lamp docker project I have this config file: Docker4lamp xdebug instructions It is designed to work with this xdebug.ini file (for use with the docker containers). xdebug.ini Of particular interest, and a setting you should look at in the xdebug.ini file is the xdebug.client_host= setting

Just going back a bit to your question, and some short history: Under the covers, the XMLHttpRequest() was a non-standard addition to the official DOM api, first added in by microsoft. While it was an important idea, as it was not standard, and not every browser maker was eager to add the feature in, so there's still code floating around that was aimed at specific browsers (microsoft in particular, as they were the inventor of it). With that said, it's at the core of all "ajax". The acronym "AJAX" is short for "Asynchronous JavaScript and XML" which in reality rarely involves XML anymore. Most people use json as the data transport format and not xml. $.ajax() is the grandparent of javascript libraries: jquery. Just a quick aside, but Jquery was the first to popularize taking advantage of the fact that javascript allows you to name a variable '$'. It doesn't own the use of $, being that it's just an alias for the jquery object, but regardless, there's so much code around that used demonstrated $.ajax() people still associate it with jquery, and to be fair, it was a nice improvement over hand coding all DOM manipulation code yourself. The ajax() method is just a small part of jquery, but it's still popular with many developers for its simplicity and ease of implementation. It was also created prior to a number of improvements to javascript itself, in particular ES6. And it's still the best known wrapper around XMLHttpRequest, although there have been any number of other libraries around that people used to do the same thing. In recent years, people have moved away from jquery (which is a large library) in favor of other more lightweight and problem specific libraries. In the ajax coding world, one popular competitor to using jquery for ajax is Axios. As for the fetch api, it is an entirely different animal, being that it was designed as an alternative to the use of XMLHttpRequest and was part of an initiative to provide more robust support for http request/response architecture. In other words, it was purpose built as an alternative to using XMLHttpRequest. One of the main reasons you want to write code that uses fetch, is that fetch was built on top of ES6 and inherently uses Promises. Just in case you aren't clear on this, prior to promises, people used callbacks. The more complicated the code the more likely you were to have a mess of interwoven callbacks, leading to the phrase "callback hell". So promises were introduced into the language as an alternative to callbacks. The fetch api returns a Promise object, and you will often see code that uses it that way, with a chain of code like this: fetch(url, options) .then((response) => response.json()) .then((data) => { console.log(data); }); You might also notice, that using fetch, not unlike using the native XMLHttpRequest function is built into the browser. You don't need a library to do it. Looking back on it, what Axios attempted to do, was bridge the gap between the introduction of Promises and an api that allowed you to write promise based code, only under the covers it was still using XMLHttpRequest. Unlike Axios, you don't need any library... just put your fetch code in there, and it already hides lots of complexity and works for you. Last but not least, given the intrinsic use of Promises, anyone can also take advantage of the syntactic sugaring of Async Await when writing your fetch api code.

If you find video material helpful, this channel is an amazing resource: If you look through the playlist, you can cherry pick individual videos for topics like OOP, Namespaces, Composer etc.

What you are trying to do is ill advised. Perhaps if you explained the problem you are trying to solve, we might be able to provide a better option. It would help you a good deal, if you understood what namespaces are for. Namespaces were added in php (as in many other languages) so that library developers could use the same names for classes (or functions) and not have collisions in the global name space. Use statements are ways of referencing classes that are defined within a namespace. Then there is autoloading, which is built into PHP. PHP comes with the option to configure a set of directories that will be searched, should the code reference a class that it does not have loaded. There are now standards for how autoloaders can work with namespacing to determine where classes are, and how they are laid out in the filesystem. As to what you appear to be trying to do, the standard way of wrapping a component library, would be to create your own class, which does all the things you are trying to do with the function. It could be as simple as the class definition, with a constructor method, and the method you want to call to wrap all the code you've shown. While it goes against the best practice pattern of Dependency injection, this new class could instantiate phpmailer in it's constructor, and store it in a private variable. Then you would just have change the code to use the private variable. <?php // Class MyMailer namespace MyOrg; use PHPMailer\PHPMailer\PHPMailer; use PHPMailer\PHPMailer\SMTP; use PHPMailer\PHPMailer\Exception; // Include PHPMailer autoloader or include necessary PHP files require_once 'PHPMailer/src/PHPMailer.php'; require_once 'PHPMailer/src/SMTP.php'; require_once 'PHPMailer/src/Exception.php'; class MyMailer { private $mail; private $config = array(); public function __construct(PHPMailer $mail=null) { if (!$mail) { $this->mail = new PHPMailer(true); // Enable exceptions $this->mail->isSMTP(); $this->mail->Host = 'mail.qss.mgo.mybluehost.me'; // Your SMTP server host $this->mail->SMTPAuth = true; $this->mail->Username = 'xxxxx'; // Your SMTP username $this->mail->Password = 'xxxxx'; // Your SMTP password $this->mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; // Enable TLS encryption $this->mail->Port = 587; // TCP port to connect to } } public function send($from, $fromName, $to, $toName, $subject, $body, $isHTML=true) { try { // Sender and recipient addresses $mail->setFrom($from, $fromName); // Sender's email address and name $mail->addAddress($to, $toName); // Recipient's email address and name // Email content $mail->isHTML($isHTML); // Set email format to HTML $mail->Subject = $subject; $mail->Body = $body; // Send the email if ($mail->send()) { echo 'Email sent successfully!'; } else { echo 'Error: Email not sent.'; } } catch (Exception $e) { echo 'Error: ' . $e->getMessage(); } } public function test() { $this-send('xxx.com', 'Your Name', 'xxx.com', 'Recipient Name', 'Test Email', 'This is a test email sent using PHPMailer'); } } At this point, you can require_once your class where you need it, and you are ready to test with something as simple as this: require_once('/path/to/MyMailer.php'); use MyOrg\MyMailer; $mail = new MyMailer(); $mail->test();

In the future a couple of things that will help. use the code tags feature of the forum, as Barand did. It's easier for you and for us to read your code. What was missing from your code was an explanation of what the code was "supposed to do", and thus what did not work the way you expected it to. The whole of computer science is not understood in a short period of time. Oftentimes people start learning a computer language, and once they are part way into the syntax, they find themselves lost and confused, because they don't have the fundamental understanding of how computers work. In this case the fundamental idea is "What is a string?" Most computer languages have strings, and in general, they share at least one similarity, and that is that they are a series of characters in a contiguous area of memory. The underlying values in computer memory are always numbers, so you need some sort of scheme (typically called a charset) that determines how a value in a charset table maps to an actual character. Javascript actually uses the UTF-16 charset, which will use either 2 bytes or 4 bytes to represent a particular character, but you don't have to really think of it in that way. Rather you can thing of a string as a sequence of characters in memory (or an array). Your code appears to be an exploration of this. Of course in javascript strings are objects, which is not the case in many other languages. Javascript as a language is also odd and quirky, and was purpose built originally to run inside a browser, so it's hard to separate it from html and css, and http and internet networking, all things that can have a depth to them that in combination is confusing. I often advise people to get good with a note taking app like notion or evernote or onenote and to make sure you note when there's a topic you don't understand. Then go through these in your spare time and research and study them. There are good resources and poor ones, so you may have to dig into a particular topic using a few different resources until you get one that sticks. For example, here is a very detailed blog post explaining what UTF-16 is and how it works: https://dmitripavlutin.com/what-every-javascript-developer-should-know-about-unicode/ or this more general introduction to character sets with some javascript specific code examples: https://www.honeybadger.io/blog/encode-javascript/#:~:text=js%2C text data is typically,working with other character encodings.

You need to actually use a place object, which you get by adding a listener to the autocomplete "place_changed" event. Something more like this: // script.js let autocomplete; function initialize() { const acInputs = document.getElementById('JobAddress'); const options = { types: ['geocode'], componentRestrictions: { country: 'uk' }, fields: ['formatted_address'], types: ['address'], }; autocomplete = new google.maps.places.Autocomplete(acInputs, options); autocomplete.addListener("place_changed", fillInAddress); } function fillInAddress() { // Get the place details from the autocomplete object. const place = autocomplete.getPlace(); console.log(place.formatted_address); return; } initialize(); Also your script should load after the body, and use defer. <body> <form> <div class="form-group"> <label for="exampleFormControlInput1">Job Address</label> <input type="text" class="form-control maps-autocomplete" id="JobAddress"> </div> </form> <script type="text/javascript" src="script.js" defer></script> </body>

For future reference, please use the code tags feature of the forum, and not a picture of your code.

You might consider switching to the places api.

A couple of things: A way to mitigate the potential for sql injection (even if this is a backoffice tool) would be to cast the company id parameter to integer. $id = (int)$_GET['COMPANY_ID']; See Danish's post to you for some helpful improvements. Indeed you should use bound parameters as shown. With that said, it's not relevant to your script not working. Also omit the ending tag in your php scripts. ( ?> ) . Just scanning the code provided, it seems likely there is an issue with the database connection on the production server. You didn't provide that code but you probably aren't catching connection errors in dataconn/connection.php

The | is just an OR. (This thing)|(that thing). There are 2 great regex testing sites you should try. They can really help you experiment and understand how regex works. First there is https://regex101.com/ 2nd is: https://regexr.com/ They both have resources and a testing interface that is really useful. I have loaded the regex I provided with some tests into regexr here: https://regexr.com/7tc1q One thing to keep in mind is that the testing tools don't allow you to change the delimiter from the default of /. You can continue to use the slash delimiter without issue, so long as you escape any slashes: \/ Note that you do not need to escape slashes inside a character class ie. [ ."/ ]

Seems pretty cut and dry that you just need to add an OR to optionally match the "shorts/". I don't know if the rest of the code will also return the data you are looking to scrape or not. preg_match('%(?:youtube(?:-nocookie)?\.com/(?:[^/]+/.+/|(?:shorts/)?|(?:v|e(?:mbed)?)/|.*[?&]v=)|youtu\.be/)([^"&?/ ]{11})%i', $linkurl, $match);

Sure thing. Mantis was used by a lot of companies once upon a time. You don't see it used as much these days, since it's well over 20 years old, and PHP has changed a lot in that time. With that said, there is still a community that has been updating it and fixing bugs. It has a fairly antiquated structure (doesn't implement a standard MVC pattern) but it's a nice product from what I recall.
