如何上传带文字的照片？

Question

这是学生资料信息表格，当我提交表格时，它工作正常，所有数据都完美保存到 mysql 表中，但我想上传带有信息的照片

当我填写表格并在提交表格后附上图片时

图片目录不上传，但mysql表中的照片名称保存完美，但不上传到图片文件夹。

我该怎么做，请帮我解决这个问题？

提交表格

Answer 1

将<form action="" method="post"> 更改为<form action="" method="post" enctype="multipart/form-data">

Answer 2

您的表单标签中缺少enctype = multipart/form-data ... 如果您没有设置enctype，则不会填充$_FILES 数组。 所以使用

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

检查文件夹权限和 php.ini 中的以下设置

file_uploads
upload_max_filesize
max_input_time
memory_limit
max_execution_time
post_max_size

当您使用此功能时，您无法使用 $_POST 访问文件信息，而只能通过 $_FILES 访问文件信息，例如 $_FILES['photo']['name']

修复

替换

$photo = mysql_real_escape_string(htmlspecialchars($_POST['photo']));

与

$photo = mysql_real_escape_string(htmlspecialchars($_FILES['photo']['name']));
