使用 echo 语句显示完整 URL 到上传的图像

Question

我找到了一个非常适合需要的上传脚本，因为它可以重命名图像 here。

效果很好，但需要 mod 验证以便在上传后显示完整的 URL 图片。

在一定程度上工作但卡住了，需要输入。

我的 mod 上面引用的脚本：

$url  = isset($_SERVER['HTTPS']) ? 'https://' : 'http://';
        $url .= $_SERVER['SERVER_NAME'];
        $url .= $_SERVER['REQUEST_URI'];

        echo dirname(dirname($url)).$uploadResult;
        echo "<br />";
        echo "<br />";
        echo "<a href='$uploadResult' target='_blank'><img src='$uploadResult' alt='picture'></a><br/>";
        echo "<br />";
        echo "<form><input name='imgcode' size='60' type='text' value='$uploadResult' /></form>";
        echo "<br />";

上面的输出是这样的：

我遇到的问题是：需要从路径 (../images/01092016211821.gif) 中删除 ..

探索并尝试了 str_replace 功能，但无法正常工作。

还想回显输入区域内的完整图像 URL 路径，以便于复制。

提前感谢 advice/solution。

这是完整的脚本...

        $destination="../images/";
        if (!file_exists($destination)) {       // If 'destination' folder dosn't exist, create
            mkdir($destination);

我的解决方案基于@Forbs 回复的输入：

<?php   
    if(isset($_POST["Send"])){      // If form is submited
        require_once("uploadClass.php");    
        $file=$_FILES["fileField"];                 // Get file from form

        $destination="../images/";
        if (!file_exists($destination)) {       // If 'destination' folder dosn't exist, create
            mkdir($destination);
        }

        $process=new Upload($destination);      // Set 'destination' as new default destination folder for upload

        $uploadResult=$process->executeUpload($file);   // Attach file to upload process

        $url  = isset($_SERVER['HTTPS']) ? 'https://' : 'http://';
        $url .= $_SERVER['SERVER_NAME'];
        $url .= $_SERVER['REQUEST_URI'];

        if (substr($uploadResult,0,2) == "..")
        $uploadResult = substr($uploadResult,2);

        echo dirname(dirname($url)).$uploadResult;
        echo "<br />";
        echo "<br />";

        }
?>

<form action="?" method="POST" enctype="multipart/form-data">
    <table id="dyntable" class="table table-bordered">
        <tr>
            <td>
                File
            </td>
            <td>
                <input type="file" name="fileField" id="fileField" placeholder="">
            </td>
        </tr>
        <tr>
            <td colspan="2">
                <center>
                    <button type="submit" name="Send">Send</button>
                    <button type="reset">Reset</button>
                </center>
            </td>
        </tr>
    </table>
</form>

<textarea id="myText" rows="3" cols="80"><?php echo dirname(dirname($url)).$uploadResult; ?></textarea>

很好地解决了我的问题，足以完成项目。

Answer 1

1) 如果前两个句号正确，请将其删除？

 if (substr($uploadresult,0,2) == "..")
    $uploadresult = substr($uploadresult,2);

2) 为什么不把输入改成

value ='{dirname(dirname($url).$uploadresult)}' 来解决这个问题？

使用 echo 语句显示完整 URL 到上传的图像
