TinyMCE版本：4.6.5
我的表单和tinyMCE编辑器正在“public_html/adm”方向工作，我试图将图像上传到“public_html/images/upload”。
tinyMCE初始化

tinymce.init({
        selector: '.mytextarea',
        plugins: 'advlist autolink link lists charmap print preview media textcolor hr table image code powerpaste',
        toolbar: 'undo redo | insert | styleselect | bold italic forecolor backcolor | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent hr | link image table code ',
        powerpaste_word_import: "prompt",
        menubar: false,
        min_height: 300,
        entity_encoding : "raw",
        // enable title field in the Image dialog
        image_title: true, 
        // enable automatic uploads of images represented by blob or data URIs
        automatic_uploads: true,
        // URL of our upload handler (for more details check: https://www.tinymce.com/docs/configure/file-image-upload/#images_upload_url)
        images_upload_url: 'postAcceptor.php',
        // here we add custom filepicker only to Image dialog
        file_picker_types: 'image', 
.
.
.

postAcceptor.php

<?php

  $imageFolder = "../images/upload/";
  reset ($_FILES);
  $temp = current($_FILES);
  if (is_uploaded_file($temp['tmp_name'])){
   
    if (preg_match("/([^\w\s\d\-_~,;:\[\]\(\).])|([\.]{2,})/", $temp['name'])) {
        header("HTTP/1.0 500 Invalid file name.");
        return;
    }
    if (!in_array(strtolower(pathinfo($temp['name'], PATHINFO_EXTENSION)), array("gif", "jpg", "png"))) {
        header("HTTP/1.0 500 Invalid extension.");
        return;
    }
    $filename = md5(date('YmdHis')).'.jpg';
    $file = $imageFolder.$filename;
    move_uploaded_file($temp['tmp_name'], $file);
    echo json_encode(array('location' => $file));
  } else {
    header("HTTP/1.0 500 Server Error");
  }
?>

在我上传我的图像后，它会像这样附加在文本区域上。

<p><img title="logo.png" src="../images/upload/0a13617f5d569df6c616578df855c92a.jpg" alt="" width="335" height="292" /></p>

问题是我的图像是不正确的渲染，除非我改变图像路径像这样。

<img title="logo.png" src="../../images/upload/0a13617f5d569df6c616578df855c92a.jpg" alt="" width="335" height="292" />
