$ARR[$i] == $NEEDLE ? $Count++ : $Count I am using it in: private function _countIf($ARR, $NEEDLE){ $Count = 0; for($i = 0; $i < count($ARR); i++){ $ARR[$i] == $NEEDLE ? $Count++ : $Count } return $Count; }

ok... I'm still struggling with PHP syntax, my editor's linting keeps flagging a line as incorrect. it's supposed to read as " when d1 minus 1 is less than or equal to d2 with d2 being less than or equal to d1 plus 1" so in other words its supposed to be true if d2 is between d1 minus 1 and d1 plus 1, inclusive. I don't want d2 being the previous number, the same number or the next number relative to d1. The same goes for d3, d4, and d5 (4 and 5 are un coded because why code in errors). That being said... This isn't exactly my correct goal but I'm not sure how to code what I really want... Rules a 3 - 5 digit combo (0 - 99 per digit) where: 1. the numbers are not in order. (1,2,3,4 or 55,56,57,58,59 or 4,3,2,1 or 59,58,57,56,55) 2. no more than 2 numbers in the combo may be the same. (45,12,67,12,78 is ok 17,35,17,24,17 is not) 3. repeat numbers may not occur next to each other (45,12,67,12,78 = valid 45,67,12,12,78 = invalid) I can't seem to find a good way to test this without the commands I know from other languages like CountIf, Iffn and RandSamp. (those are Ti-Basic commands) I know "please do it for me" is frowned upon, and hate saying it (I'd rather learn to do it myself), but if anyone can explain how to do this I'd really appreciate it.

Not sure what is going on I tried everything (well, that I could think of) . . . any ideas are welcome (hopefully new ones - getting frustrated :/) if ($mysqli->prepare("INSERT INTO solcontest_entries (title, image,content, user, contest) VALUES ($title, $image, $content, $userid, $contest")) { $stmt2 = $mysqli->prepare("INSERT INTO `solcontest_entries` (title, image, content, user, contest) VALUES (?, ?, ?, ?, ?)"); $stmt2->bind_param('sssss', $title, $image, $content, $userid, $contest); $stmt2->execute(); $stmt2->store_result(); $stmt2->fetch(); $stmt2->close(); } else { die(mysqli_error($mysqli)); } Error I get from die mysqli_error: "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' of the site's lead ad, user_61609201, contest_1' at line 1" I have also tried $mysqli->query no change occured. I added the "if else die" statement because it was giving no errors, but not adding it to the database. It gives the error where $content is supposed to be inserted. Various combos and singles I tried for the variable: //$content = cleansafely($_POST['content']); //$content = mysqli_real_escape_string ($mysqli, $_POST['content']); //$content = cleansafely($content); $content = $_POST['content']; If any more information is needed please let me know.

Ok this is puzzleing. I am geting "Could not delete data: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '1' at line 1". but its is deleting the entry that needs to be removed. The "1" is the entry. Just not sure what is causing the error. I do have another delete php but I have put that on the back burning for the time being. <?php $con = mysqli_connect("localhost","user","password","part_inventory"); // Check connection if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } else { $result = mysqli_query($con, "SELECT * FROM amp20 "); $amp20ptid = $_POST['amp20ptid']; // escape variables for security $amp20ptid = mysqli_real_escape_string($con, $_POST['amp20ptid']); mysqli_query($con, "DELETE FROM amp20 WHERE amp20ptid = '$amp20ptid'"); if (!mysqli_query($con, $amp20ptid)); { die('Could not delete data: ' . mysqli_error($con)); } echo "Part has been deleted to the database!!!\n"; mysqli_close($con); } ?>

Hi guys I have this code below and all works fine when submitting this online application apart from when someone types either ' # & into one of the comment fields in which it throws up the error.

I am using this API https://github.com/blocktrail/blocktrail-sdk-php. I am suppose to add this to top of my directory where I want to initialize the API. require 'vendor/autoload.php'; use Blocktrail\SDK\BlocktrailSDK; But the second line gives me an error. use Blocktrail\SDK\BlocktrailSDK; Parse error: syntax error, unexpected 'use' (T_USE) in C:\xampp\htdocs\site\templates\header.php on line 12 Is the "use" a correct syntax for php? Why is it giving me an error?

I am taking a form that has been created and now trying to incorporate it into WP. The form is filled out multiple times per session. The form when filled out will generate an ID that is used to track the form submissions until completed. The problem that I'm running into is that the code is using a URL structure that breaks on the install. I'm not sure what to tell the code to look for as the URL. I hope I'm making sense. This is my first dive into WP dev.

So I am creating php script to make my navigation for a website. I've gathered bits and pieces from books/online forums. One thing that is confusing me is what does the "?" in this line accomplishes? $currentTitle=isset($mainMenu[$currentPage]) ? $mainMenu[$currentPage] : ''; As you can imagine this is a hard question to find an answer to because of the use of ?'s in <?php. Also a little confused on the : symbol also. I am writing this script to keep track of the current page to generate a css class to be modified, which works. But then I also thought id have it generate the titles too but when i echo this.. The script goes bad. echo' <title> ',(is_empty($currentTitle) ? '' : $currentTitle.' - '),$siteTitle,' </title> ' I would be grateful for any help! Thanks in advance.

I’m never altogether sure when something is maybe going on but I think this time it’s just my typing it in wrong. I’m working on some Youtube Wordpress tutorials and I’m having an issue with the script finding the style.css file. Of course the script is is calling a Wordpress function but it is after all written in php. So here’s the function… function nq_styles() { wp_enqueue_style('style', get_stylesheet_uri(style.css)); } This function was working until I moved the the style.css fill up one level to its own folder. So now the file resides in css/style.css So I change dthe file path in the function to… function nq_styles() { wp_enqueue_style('style', get_stylesheet_uri(css/style.css)); } I’ve tried a couple of different structures, for example… /css/style.css or ./css/style.css or even //css/style.css and nothing seems to be working. What am I missing ? BTW I couldn't get the "Code" button to work

Hello guys! I have literally started learning how to code. And I have come to the point when I got to deal with elseif syntax which is not working properly and messes up everything I have done so far. Here's the script $password = "tulip"; if ($password == "tulip") { echo '<b>Hello!</b><br> Welcome to the website Blaise!'; } else { echo '<b> The password or login is incorrect <br> Please try again </b>'; } elseif ( $password == "daisy") { echo '<b> Welcome Kate! </b>; } When I type in "daisy" nothing goes on and everything just gets stuck. Any help or explanation? Thanks
