i’m working on app that takes a shot from the camera and upload the picture to the server so this is my code:-

<form id="theform" action="upload.php" onsubmit="event.preventDefault(); return myFunction();" method="post" enctype="multipart/form-data">
          <input id="file" name="uploadedFile" onchange="uptoserver();" style="display:none;"type="file" accept="image/*" capture="camera">
          <div class="row justify-content-center">
          <button type="submit"  class="btn wbtn border rounded-pill" style="font-family:Hana; font-size:32px;">
            <img src="style\image\camera.png" width="64" />&nbsp;تصوير النمودج&nbsp;
          </button>&nbsp;
          </div>
          </form>

and upload.php :-

<?php 
$target_path = "uploads/";
$target_path = $target_path . basename( $_FILES['uploadedFile']['name']); 
if(move_uploaded_file($_FILES['uploadedFile']['tmp_name'], $target_path)) {
    echo "جاري إضافة الملف  ".  basename( $_FILES['uploadedFile']['name']). 
    " إلى جدول ملف إكسل";
   echo "<script>document.write(readfile(\"".$target_path."\"));</script>";
   $stringPath = $target_path; //PASSING NAME PARAM
    // how can i pass the Name to prepare.php
    printf($stringPath);
} else{
    echo "There was an error uploading the file, please try again!";
}
?>

the problem is that this upload script is uploading the picture but its corrupted file with size of 0mb so how can i fix this problem
