Nicht in der Lage, Bilder mit PHP korrekt zu laden

Question

So habe ich ein PHP-Skript, wo ich ein Bild von einem HTML-Formular hochladen. Die PHP-Datei sieht wie folgt aus:

<?php 
function generateRandomString($length = 10) { 
$characters = 
'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'; 
$charactersLength = strlen($characters); 
$randomString = ''; 
for ($i = 0; $i < $length; $i++) { 
    $randomString .= $characters[rand(0, $charactersLength - 1)]; 
} 
    return $randomString; 
} 


$herman_is_the_best; 

if(isset($_POST["place"]) && isset($_POST["submit"])) { 
$herman_is_the_best = $_POST["place"]; 


$target_dir = "../places/" . $herman_is_the_best . "/" ; 
$realtarget = $target_dir . generateRandomString() . "." . 
pathinfo($target_file,PATHINFO_EXTENSION); 
$uploadOk = 1; 
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION); 
// Check if image file is a actual image or fake image 





//check if there is a folder for the location alredy 
$direction = "../places/" . $herman_is_the_best . "/"; 
if(!is_dir($direction)){ 
//make direction for place 
mkdir($direction); 


// url encode the address 
$address = urlencode($herman_is_the_best); 

// google map geocode api url 
$url = "https://maps.googleapis.com/maps/api/geocode/json?address=". $address ."&key=AIzaSyDeqk1Oc6TkKQkQph_-P_4U9jTLLJv0G98"; 

// get the json response 
$resp_json = file_get_contents($url); 

// decode the json 
$resp = json_decode($resp_json, true); 

// response status will be 'OK', if able to geocode given address 
if($resp['status']=='OK'){ 

    // get the important data 
    $lati = $resp['results'][0]['geometry']['location']['lat']; 
    $longi = $resp['results'][0]['geometry']['location']['lng']; 

    // verify if data is complete 
    if($lati && $longi){ 

     // put the data in the array 
     $data_arr = array();    

     array_push(
      $data_arr, 
       $lati, 
       $longi 
      ); 

    } 

} 

$my_file = '../places/' . $herman_is_the_best .'/cordinates.txt'; 
$handle = fopen($my_file, 'w') or die('Cannot open file: '.$my_file); //implicitly creates file 
$long = $data_arr[0]; 
$lati = $data_arr[1]; 
fwrite($handle, $long . "\r\n" 
. $lati); 

} 

if(isset($_POST["submit"])) { 
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]); 
if($check != false) { 
    echo "File is an image - " . $check["mime"] . "."; 
    $uploadOk = 1; 
} else { 
    echo "File is not an image."; 
    $uploadOk = 0; 
} 
} 
// Check if file already exists 
if (file_exists($realtarget)) { 
echo "Sorry, there was an error"; 
$uploadOk = 0; 
} 
// Check file size 
if ($_FILES["fileToUpload"]["size"] > 500000000) { 
echo "Sorry, your file is too large."; 
$uploadOk = 0; 
} 
// Allow certain file formats 
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != 
"jpeg" 
&& $imageFileType != "gif") { 
echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed."; 
$uploadOk = 0; 
} 
// Check if $uploadOk is set to 0 by an error 
if ($uploadOk == 0) { 
echo "Sorry, your file was not uploaded."; 
// if everything is ok, try to upload file 
} else { 
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $realtarget)) 
{ 
    echo "The file ". basename($_FILES["fileToUpload"]["name"]). " has 
been uploaded."; 
} else { 
    echo "Sorry, there was an error uploading your file."; 
} 
} 

} 


?> 

Der eigentliche Teil, wo die Datei hochgeladen ist die gleiche wie auf den w3 Tutorials verwendet. Ich habe etwas Code hinzugefügt, um einen Platzordner zu erstellen, wenn es vorher keinen Platzordner für diesen Ort gibt, und füge die Koordinaten des Platzes in einer txt-Datei hinzu, die Koordinaten genannt wird.

Die seltsame Sache ist, dass manchmal die Datei in das übergeordnete Verzeichnis hochgeladen wird und der Ort-Ordner nicht erstellt wird. In anderen Fällen wird der Ordner "Ort" erstellt und die Bilddatei wird überhaupt nicht hochgeladen.

Also meine Frage ist, was hier vor sich geht. Ich verstehe nicht, warum es manchmal eine Sache macht und andere nicht mit genau dem gleichen Bild.

<form action="upload.php" id="uploadForm" class="" method="post" enctype="multipart/form-data" style="width:100%; height:100%; font-size:400px"> 
    <input type="file" class="inputfile" name="fileToUpload" id="fileToUpload"> 

     <label for="fileToUpload" style="margin-left:35%; margin-top:8%; width:30%; height:16%; text-align:center"> <img style="width:70%; margin-top:6%"src="img/image.svg"></img></label> 
    <input id="searchTextField" type="text" style="width:32%; height:50px; margin-left:33%; font-size:22pt; margin-top:30%" name="place"> 
    <script> 
    function initialize() { 
var options = { 
types: ['(cities)'] 
}; 

var input = document.getElementById('searchTextField'); 
var autocomplete = new google.maps.places.Autocomplete(input, options); 
} 

google.maps.event.addDomListener(window, 'load', initialize); 

    </script> 


    <input style="width:30%; height:8% ; font-size:23pt; margin-top:40%; 
margin-left:35%" type="button" class="btn btn-success " 
onclick="submitFirst();" id="connectWorld" value="Connect the world!" 
name="submit"> 
    <input id="submitbutton" type="submit" style="display:none"></input>  
    </form> 

Hat jemand eine Idee von was ist das Problem hier?

Versuchen Sie diesen Code:

HTML Form:

<!DOCTYPE html> 
 
<html lang="en"> 
 
<head> 
 
    <meta charset="UTF-8"> 
 
    <title>File Upload with PHP</title> 
 
</head> 
 
<body> 
 
    <form action="fileUpload.php" method="post" enctype="multipart/form-data"> 
 
     Upload a File: 
 
     <input type="file" name="file" id="fileToUpload"> 
 
     <input type="submit" name="submit" value="Upload File Now" > 
 
    </form> 
 
</body> 
 
</html>

PHP Script:

<?php 
$currentDir = getcwd(); 
$uploadDirectory = "/uploads/"; 
$errors = []; // Store all foreseen and unforseen errors here 

$fileExtensions = ['jpeg','jpg','png']; // Get all the file extensions 

$fileName = $_FILES['myfile']['name']; 
$fileSize = $_FILES['myfile']['size']; 
$fileTmpName = $_FILES['myfile']['tmp_name']; 
$fileType = $_FILES['myfile']['type']; 
$fileExtension = strtolower(end(explode('.',$fileName))); 

$uploadPath = $currentDir . $uploadDirectory . basename($fileName); 

if (isset($_POST['submit'])) { 

    if (! in_array($fileExtension,$fileExtensions)) { 
     $errors[] = "This file extension is not allowed. Please upload a JPEG or PNG file"; 
    } 

    if ($fileSize > 2000000) { 
     $errors[] = "This file is more than 2MB. Sorry, it has to be less than or equal to 2MB"; 
    } 

    if (empty($errors)) { 
     $didUpload = move_uploaded_file($fileTmpName, $uploadPath); 

     if ($didUpload) { 
      echo "The file " . basename($fileName) . " has been uploaded"; 
     } else { 
      echo "An error occurred somewhere. Try again or contact the admin"; 
     } 
    } else { 
     foreach ($errors as $error) { 
      echo $error . "These are the errors" . "\n"; 
     } 
    } 
} 


?> 

Als Alternative zum Schreiben Ihres eigenen Codes sollten Sie eine Open-Source-Image-Bibliothek PHP upload in Erwägung ziehen, die Ihnen den Aufwand erspart, große Mengen Code schreiben zu müssen.
