Question

我正在制作一个简单的脚本来上传图片，但有些东西对我不起作用..我尝试过evrything，但我无法弄清楚为什么文件没有保存在服务器上以及为什么路径没有保存在mysql中。。

PS：没有PHP错误..

submit.php

Answer 1

替换<form onSubmit="return validateForm()" action="offer_save.php" method="post" class="form-horizontal form-label-left input_mask">

使用<form onSubmit="return validateForm()" action="offer_save.php" method="post" class="form-horizontal form-label-left input_mask" enctype="multipart/form-data" >

通过使用

转义字符串来清理用户输入

mysqli_real_escape_string($vairable)

文件上传+ MySql不起作用
