Question

执行单一分配，需要导入表数据并将数字转换为十六进制数。我尝试使用unHex（）但转换字符串时非常混乱。有没有更简单的方法来转换它们？

这是表数据的屏幕截图：

Table table;

void setup() {
  size(200, 200);
 background(255);
  table = loadTable("msfw15.csv", "header");



}

void draw() {
  //Getting tags, probably an easier way.
  String work = table.getString(0, 1);
  String fashion = table.getString(1, 1);
  String blogger = table.getString(2, 1);
  String girlsnight = table.getString(3, 1);
  String backstage = table.getString(4, 1);
  String ootd = table.getString(5, 1);
  String melbourne = table.getString(6, 1);
  String sydney = table.getString(7, 1);
  String emergingdesigner = table.getString(8, 1);
  String fashiongram = table.getString(9, 1);
  String foodblogger = table.getString(10, 1);
  String hiphop = table.getString(11, 1);
  String muji = table.getString(12, 1);
  String monochrome = table.getString(13, 1);
  String swag = table.getString(14, 1);
  String alannahhill = table.getString(15, 1);
  String popsofcolour = table.getString(16, 1);
  String stylesketch = table.getString(17, 1);
  String artist = table.getString(18, 1);
  String designer = table.getString(19, 1);
  String model = table.getString(20, 1);
  String vogue = table.getString(21, 1);
  String knitwear = table.getString(22, 1);
  String knitting = table.getString(23, 1);

  color workd = unhex("FF" + work);
  fill(workd);
  noStroke();
  rect(50, 50, 100, 100);

}

首先，我认为你真的需要了解<?php session_start(); if (!$_SESSION['loggedInUser']) { header("Location: login.php"); } $resultMessage = null; include ('db.php'); $query = "SELECT * from user"; $result = mysqli_query($connection, $query); mysqli_close($connection); ?> <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>Client Area</title> </head> <body> <?php // Check for Header Injections function has_header_injection($str) { return preg_match( "/[\r\n]/", $str ); } $missingitemname = '<p><strong> Please Enter Item Name</p></strong>'; if (isset($_POST['submit_form'])) { $itemname = $_POST["item-name"]; $brandname = $_POST["brand"]; $description = $_POST["description"]; $availability = $_POST["availability"]; $contact = $_POST["contact-p"]; $address = $_POST["address"]; $email = $_POST["email"]; $location = $_POST["location"]; $file = $_FILES["attach"]; if (!$itemname) { $errors .= $missingitemname; } else { $itemname = filter_var($itemname, FILTER_SANITIZE_STRING); } if (!$email) { $errors .= $missingemail; } else { $email = filter_var($email, FILTER_SANITIZE_EMAIL); if (!filter_var($email, FILTER_VALIDATE_EMAIL)) { $errors .= $invalidEmail; } } if (!$brandname) { $errors .= $missingbrandname; } else { $brandname = filter_var($brandname, FILTER_SANITIZE_STRING); } if ($errors) { $resultMessage = '<div class="alert alert-danger">'. $errors .'</div>'; } else { $to = "adamskhan123@gmail.com"; $subject ="New Contact"; $message ="<p>Item Name: $itemname.</p> <p>Brand: $brandname.</p> <p>Description: $description.</p> <p>Availability: $availability.</p> <p>Contact Person: $contact</p> <p>Email: $email</p> <p>Location: $location</p> "; $headers ="Content-type: text/html"; if (mail($to, $subject, $message, $headers)) { $resultMessage = '<div class="alert alert-success">Thank You. Your message has been sent</div>'; } else { $resultMessage = '<div class="alert alert-danger">Sorry Please Try Again.</div>'; } } } ?> <div class="container"> <h1>PinTribe</h1> <p>Welcome <?php echo $_SESSION['loggedInUser']; ?></p> </div> <div class="top-content"> <div class="inner-bg"> <div class="container"> <div class="row"> <div class="col-sm-8 col-sm-offset-2 text"> </div> </div> <div class="row"> <div class="col-sm-6 col-sm-offset-3 form-box"> <div class="form-top"> <div class="form-top-left"> </div> </div> <div class="form-bottom"> <?php echo $resultMessage; ?> <form role="form" action="dashboard.php" method="post" class="login-form" enctype="multipart/form-data"> <div class="form-group"> <label class="sr-only" for="item-name">Item Name</label> <input type="text" name="item-name" placeholder="Item Name" class="username form-control" id="item-name"> </div> <div class="form-group"> <textarea type="text" name="description" placeholder="Description" class="description form-control" id="description" rows="5"></textarea> </div> <div class="form-group"> <label class="sr-only" for="email">Email</label> <input type="email" name="email" placeholder="Email.." class="email form-control" id="email"> </div> </div>循环。通过该表应该只需要几行代码。 Here是指向for循环引用的链接。

接下来，我建议您查看the unhex() reference：

除此之外，您需要更准确地了解您对此感到困惑的内容。 String hs = "FF006699"; int hi = unhex(hs); fill(hi); rect(30, 20, 55, 55);函数如何处理你的预期呢？

处理：与UnHex混淆，有更简单的方法吗？
