我创建了一个测试表单，只是试图将图像插入mysql的“学生” 表和“图像” 文件夹中。但是图像不能插入数据库和图像文件夹。下面的代码只是一个测试，我想提交，但不是。
**Mysql Database:**
CREATE TABLE STUDENT
(
STD_SL_NO INT(10) NOT NULL AUTO_INCREMENT,
STD_NAME VARCHAR(140) NOT NULL,
STD_FNAME VARCHAR(140) NOT NULL,
STD_MNAME VARCHAR(140) NOT NULL,
STD_BDATE DATE NOT NULL,
STD_GENDER VARCHAR(10) NOT NULL,
STD_RELIGIOUS VARCHAR(20) NOT NULL,
STD_CURR_ADDRESS TEXT NOT NULL,
STD_MOBILE CHAR(12),
STD_ROLL_NO INT(10) NOT NULL,
STD_PHOTO BLOB,
USER_NAME VARCHAR(50),
ENTRY_DATE TIMESTAMP (6),
PRIMARY KEY(STD_SL_NO, STD_ROLL_NO, STD_REG_NO)
)ENGINE=InnoDB;
**Form HTML & PHP:**
<!DOCTYPE html>
<html>
<head>
<title> Student Information Entry Form </title>

<body>
<form name="form1" action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post">

使用此api。只需修改
/ 上传徽标图像的功能 /
public function upload_logo($filename,$temp_name,$filesize,$dir){
global $postClass;
$upload_size = imagesize*1424*1424;
$file_name = $filename;
if (!file_exists($dir))
{
mkdir($dir, 0777, true);
}
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$mime = finfo_file($finfo, $temp_name);
if($mime == 'image/jpeg' || $mime == 'image/png' || $mime == 'image/jpg' || $mime == 'image/JPG' || $mime == 'application/pdf')
{
if($filesize < $upload_size)
{
$temp = $temp_name;
$extention = explode('.',$file_name);
$name = rand(1,100).'_'.time().'.'.$extention[1];
if($mime == 'application/pdf'){
if(move_uploaded_file($temp,"$dir/$name")){
if(strpos($dir, '/') !== false){
$dir1 = explode('/', $dir);
$dir = $dir1[1];
}
else{
$dir =$dir;
}
return $dir.'/'.$name;
}
else{
return 1;
}
}
else{
$image = $postClass->compress($temp, "$dir/$name", 70);
//if(move_uploaded_file($temp,"$dir/$name"))
if($image)
{
if(strpos($dir, '/') !== false){
$dir1 = explode('/', $dir);
$dir = $dir1[1];
}
else{
$dir =$dir;
}
return $dir.'/'.$name;
}else{
return 1;
}
}
}else{
return 2;
}
}else{
return 3;
