我正在 wordpress 模板中尝试以下代码：
<?php
//connect to database. Username and password need to be changed
mysql_connect("localhost", "username", "password");
//Select database, database_name needs to be changed
mysql_select_db("database_name");
if (!$_POST['uploaded']){
//If nothing has been uploaded display the form
?>
<form action="<? echo $_SERVER['PHP_SELF']; ?>" method="post"
ENCTYPE="multipart/form-data">
Upload:<br><br>
<input type="file" name="image"><br><br>
<input type="hidden" name="uploaded" value="1">
<input type="submit" value="Upload">
</form>
<?
}else{
//if the form hasn't been submitted then:
//from here onwards, we are copying the file to the directory you made earlier, so it can then be moved
//into the database. The image is named after the persons IP address until it gets moved into the database
//get users IP
$ip=$REMOTE_ADDR;
//don't continue if an image hasn't been uploaded
if (!empty($image)){
//copy the image to directory
copy($image, "/temporary/".$ip."");
//open the copied image, ready to encode into text to go into the database
$filename1 = "/temporary/".$REMOTE_ADDR;
$fp1 = fopen($filename1, "r");
//record the image contents into a variable
$contents1 = fread($fp1, filesize($filename1));
//close the file
fclose($fp1);
//encode the image into text
$encoded = chunk_split(base64_encode($contents1));
//insert information into the database
mysql_query("INSERT INTO images (img,data)"."VALUES ('NULL', '$encoded')");
//delete the temporary file we made
unlink($filename1);
}
//end
}
?>
我在我的网络根目录中创建了一个名为“临时”的目录。这个文件在里面：wp-content/themes/mytheme/ 目录。
我还将目录权限设置为 chmod 777。
当我尝试上传时，什么也没有发生，也没有任何东西上传到目录中，也没有任何东西添加到数据库中。
我尝试上传后发生的所有事情都是页面重定向到主页。
