Question

我有一个将文本和图像上载到服务器/数据库的表单，除我使用file_exists之外，其他所有条件均适用。

这是怎么了？

if(isset($_FILES["tipimage"]) && $_FILES["tipimage"]["error"] == 0){
        $allowed = array("jpg" => "image/jpg", "jpeg" => "image/jpeg", "gif" => "image/gif", "png" => "image/png");
        $filename = $_FILES["tipimage"]["name"];
        $filetype = $_FILES["tipimage"]["type"];
        $targetDir = "uploads/";
        $targetFilePath = $targetDir . $filename;

        // Verify file extension
        $ext = pathinfo($filename, PATHINFO_EXTENSION);
        if(!array_key_exists($ext, $allowed)) {
            $error .= "Invalid File Format<br>";
          } 
        }

        if(file_exists("upload/" . $_FILES["tipimage"]["name"])){
          $error .= "File" . $_FILES["tipimage"]["name"] . " already exists.<br>";
        }

          else if (move_uploaded_file($_FILES["tipimage"]["tmp_name"], $targetFilePath)){
            $successmsg .= "<div class='alert alert-success'>Image - " . $filename . " Uploaded Successfully!</div>";
          }


      if($error) {
        $dangererror = "<div class='alert alert-danger'>";
        $dangererror .= $error;
        $dangererror .= "</div>";
      }

这是由于一个简单的错字。

我的变量设置为“上传”

library(dplyr)
library(ggplot2)
mtcars %>% 
    ggplot(aes(am, wt, group = am, label = wt)) +
    geom_boxplot(outlier.shape = NA) +
    geom_jitter(position = position_jitter(seed = 1)) +
    geom_text(position = position_jitter(seed = 1))

在我写的if语句中，“ upload”是正确的路径

$targetDir = "uploads/";

PHP正确使用File_Exists
