Question

我无法在目标文件夹中看到任何上传的图片。我也试过if（move_uploaded_file（$ HTTP_POST_FILES ['memphoto'] ['tmp_name']，$ target。$ HTTP_POST_FILES ['memphoto'] ['name']））而不是if（copy（$ _ FILES ['photo'] ['tmp_name']，$ uploadimages））但没有得到任何结果。任何人都可以帮助我。

<?php
  if ((isset($_FILES['photo']) && ($_FILES['photo']['size'] > 0)) 
  {
   $typ = $_FILES['photo']['type'];
   if($typ == "image/gif" || $typ == "image/png" || $typ == "image/jpeg" || $typ ==  "image/pgif" || $typ == "image/ppng" || $typ =="image/pjpeg" || $typ =="image/jpg")
   {
        $uploaddir = "images/";
        $uploadimages = $uploaddir.basename($_FILES['photo']['name']);
        if(copy($_FILES['photo']['tmp_name'], $uploadimages))
        {
           echo "File successfully copied";
           $query = "UPDATE $tbl_name SET photo='$uploadimages WHERE ID='$ID' ";
           if (!mysql_query($query))
           {
              die('Error: ' . mysql_error());
              mysql_close();
           }
        }
        else{echo "Copy unsuccessful";}
    }
    else{
                echo "Incorrect file type";
    }             

  }
  else {
  echo "No Photo/Signature file selected/uploaded.";
   }
?>

Answer 1

我总是使用move_uploaded_file()将上传的图片移动到目标目录。

$uploadimages = $uploaddir.$_FILES['photo']['name'];
if(move_uploaded_file($_FILES['photo']['tmp_name'], $uploadimages)){
    echo 'uploaded';
}else{
    echo 'upload failed';
}

确保您的表单标记中包含enctype="multipart/form-data"。

<form method="post" enctype="multipart/form-data">

的index.php

    <form action="<?php echo $_SERVER["PHP_SELF"];?>" method="POST" enctype="multipart/form-data">
      Select image to upload:
      <input type="file"   name="photo" />

  /* Check if folder not exists, then create it */

    /* check if files error = 0 [there are file uploaded] */
    if ($file_error === UPLOAD_ERR_OK) {
