PHP：图像未保存在服务器文件夹和数据库中（作为 URL）

Question

Currently, I created a PHP system that can allow the user to upload a photo. Now, I get this error.

PHP Warning: move_uploaded_file(images/before_4.png): failed to open stream: No such file or directory in C:\\inetpub\\wwwroot\\tgotworker_testing\\pages\\dashboard\\engineer\\view_task\\update_photo_before.php on line 28 PHP Warning: move_uploaded_file(): Unable to move 'C:\\Windows\\Temp\\phpA952.tmp' to 'images/before_4.png' in C:\\inetpub\\wwwroot\\tgotworker_testing\\pages\\dashboard\\engineer\\view_task\\update_photo_before.php on line 28

Below is my code.

<?php

    require_once '../../../../config/configPDO.php';

    $report_id = $_POST['report_id'];
    $last_insert_id = null;

    //Allowed file type
    $allowed_extensions = array("jpg","jpeg","png");

    //File extension
    $ext = strtolower(pathinfo($_FILES['uploadFile']['name'], PATHINFO_EXTENSION));

    //Check extension
    if(in_array($ext, $allowed_extensions)) {

        $defID = "before_" . $report_id;
        $imgPath = "images/$defID.png";
        $ServerURL = "http://172.20.0.45/tgotworker_testing/android/$imgPath";

        $query = "UPDATE ot_report SET photo_before = '$ServerURL', time_photo_before = GETDATE() WHERE report_id = :report_id";
        $sql = $conn->prepare($query);
        $sql->bindParam(':report_id', $report_id);
        $sql->execute();

        if ($sql){

            move_uploaded_file($_FILES['uploadFile']['tmp_name'], $imgPath); //line 28
            echo "<script>alert('Saved')</script>";
            header("Location: view_task.php?report_id=".$_POST['report_id']);

        }else{
            echo "Error!! Not Saved";
        }


    } else {
        echo "<script>alert('File not allowed')</script>";
        header("Location: view_task.php?report_id=".$_POST['report_id']);    

    }

?>

Can anyone help me to solve this problem?

Answer 1

You are using file_get_contents() on this line 28 :

move_uploaded_file(file_get_contents($_FILES['uploadFile']['name']),$imgPath);

but the function move_uploaded_file is not needing the result of it. You can just do like that instead :

move_uploaded_file($_FILES['uploadFile']['tmp_name'],$imgPath);

For your second problem with absolute path: in $imgPath maybe you should use this instead:

$imgPath="C:/inetpub/wwwroot/tgotworker_testing/android/images/$defID.png";
