Question

我有一个WordPress插件，我正在努力，我似乎遇到了问题。我需要用户能够上传图片，而不是我一直遇到这个问题：

上传目录不可写或不存在。

警告： move_uploaded_file（http://markpetherbridge.co.uk/ios/wp-content/plugins/rap/includes/productimages/78.105.162.431328735863.png） [function.move-uploaded-file]：无法打开流：HTTP包装器不支持可写连接 /home/markpeth/public_html/ios/wp-content/plugins/rap/includes/products.php 第39行

警告：move_uploaded_file（）[function.move-uploaded-file]：无法执行将'/ tmp / phpowqMlu'移动到 'http://markpetherbridge.co.uk/ios/wp-content/plugins/rap/includes/productimages/78.105.162.431328735863.png' 在 /home/markpeth/public_html/ios/wp-content/plugins/rap/includes/products.php 在第39行上传文件时出错，请重试！您已成功将test_title添加到产品列表

目录肯定存在，我甚至将CHMOD更改为777进行测试。

products.php文件如下所示：

 <?
if ('POST' == $_SERVER['REQUEST_METHOD'])
 {
global $wpdb;

$product_title = $_POST['title'];
$product_url = $_POST['url'];
$product_btn_text = $_POST['btn_text'];

// CREATE UNIQUE NAME FOR IMAGE
$remote_addr = $_SERVER['REMOTE_ADDR'];
$time = time();
$new_name = $remote_addr;
$new_name .= $time;


// IMAGE UPLOAD

$upload_dir = "http://markpetherbridge.co.uk/ios/wp-content/plugins/rap/includes/productimages/"; 

if (file_exists($upload_dir) && is_writable($upload_dir)) {
        echo "<br /> Directory exists and is fine.... <br />";
}
else {
        echo "Upload directory is not writable, or does not exist. <br />";
}

$uploadedfile = $_FILES['image_file']['name'];
$extension = explode(".", $uploadedfile);
$extensiontype = $extension['1'];

$target_path = $upload_dir;
$target_path = $target_path .$new_name .'.'.$extensiontype; 

if(move_uploaded_file($_FILES['image_file']['tmp_name'], $target_path)) {
        echo "The file ".  basename( $_FILES['image_file']['name']). 
        " has been uploaded <br />";
} else{
    echo "There was an error uploading the file, please try again! <br />";

}

$product_img = $new_name.'.'.$extensiontype;

//ADD TO DATABASE
    $wpdb->query("INSERT INTO wp_rec_amazon_product (product_title, product_url,    product_img, product_btn_text) VALUES ('$product_title', '$product_url','$product_img','$product_btn_text')");
echo "You have successfully added "  .$product_title.   " to your products list";

} else { ?>

 <form action="<?php $_SERVER['PHP_SELF']; ?>" method="POST" enctype="multipart/form-data">
<table border="0" bordercolor="none" width="50%" cellpadding="0" cellspacing="0">
    <tr>
        <td>Product Title:</td>
        <td><input type="text" name="title" value="product title" /></td>
    </tr>
    <tr>
        <td>Product Url</td>
        <td><input type="text" name="url" value="product url" /></td>
    </tr>
    <tr>
        <td>Button text</td>
        <td><input type="text" name="btn_text" value="Get your copy" /></td>
    </tr>

</table>
    <input type="file" name="image_file" />



    <input type="submit" value="Submit" />
</form>

 <?php }?>

信息被添加到数据库，它只是图像上传似乎不起作用。

有没有人有任何想法？谢谢大家。：）

Answer 1

就像@thenetimp说的那样！

move_uploaded_file的目标不能是URL。但必须是本地文件系统上的路径。

$ upload_dir必须指向本地路径，如

windows: c:/some/path
unix: /some/path

Answer 2

您的上传目录是网址这是您的问题。它需要是本地文件系统路径

此外，你有一个if条件来检查你是否可以写文件，但除了吐出文本响应之外什么都不做。你应该在那里做你的工作，而不是在if条件下。那很糟。你应该这样做。

if (file_exists($upload_dir) && is_writable($upload_dir)) {
    echo "<br /> Directory exists and is fine.... <br />";
    $uploadedfile = $_FILES['image_file']['name'];
    $extension = explode(".", $uploadedfile);
    $extensiontype = $extension['1'];

    $target_path = $upload_dir;
    $target_path = $target_path .$new_name .'.'.$extensiontype; 

    if(move_uploaded_file($_FILES['image_file']['tmp_name'], $target_path)) {
            echo "The file ".  basename( $_FILES['image_file']['name']). 
            " has been uploaded <br />";
            $product_img = $new_name.'.'.$extensiontype;

            //ADD TO DATABASE
            $wpdb->query("INSERT INTO wp_rec_amazon_product (product_title, product_url,    product_img, product_btn_text) VALUES ('$product_title', '$product_url','$product_img','$product_btn_text')");
            echo "You have successfully added "  .$product_title.   " to your products list";

    } else{
        echo "There was an error uploading the file, please try again! <br />";

    }


}
else {
    echo "Upload directory is not writable, or does not exist. <br />";
}

Answer 3

wp_upload_dir（）

将返回WordPress上传目录的本地文件路径。

你的脚本中的

，放：$ upload_dir = wp_upload_dir（）; 而不是你在那里的静态字符串。
