我正在创建PHP多图像更新页面，如果我选择了所有图像文件，而我只想更新一个和第二个图像，我的脚本将仅更新一个图像，第二个图像更新。不起作用
这是我的代码
private void registerUser(final String phone,final String otp,final String fullname,final String email, final String password, final String device_id )
{
Log.e(TAG, "otp12 " +otp11);
String tag_string_req = "req_register";
Map<String, String> params = new HashMap<String, String>();
params.put("Content-Type", "application/json");
params.put("phone",phone);
params.put("otp",otp);
params.put("fullname", fullname);
params.put("email",email);
params.put("password",password);
params.put("device_id", device_id);

答案 0 :(得分：1)
我认为您的逻辑不正确。逻辑应该是
if($_SERVER['REQUEST_METHOD'] == "POST"){
$id=$_POST['id'];
$title=$_POST['title'];
$desc1=$_POST['desc1'];
$content=$_POST['content'];
$category=$_POST['category'];
$random = substr(number_format(time() * rand(),0,'',''),0,10);
$img= $random .$_FILES['image']['name'][0];
$image_tmp= $_FILES['image']['tmp_name'][0];
$img1= $random .$_FILES['image']['name'][1];
$image_tmp1= $_FILES['image']['tmp_name'][1];
if(move_uploaded_file($image_tmp,"images/$img")){
move_uploaded_file($image_tmp1,"images/$img1");
$stmt = $con->prepare("UPDATE products SET title=?, desc1=?, content=?, category=?,img=?,img1=? WHERE id=?");
$stmt->bind_param("sssssss", $title, $desc1, $content, $category, $img,$img1, $id);
} else if (move_uploaded_file($image_tmp1,"images/$img1")) {
move_uploaded_file($image_tmp1,"images/$img");
$stmt = $con->prepare("UPDATE products SET title=?, desc1=?, content=?, category=? WHERE id=?");
$stmt->bind_param("sssss", $title, $desc1, $content, $category, $id);
}
if($stmt->execute()){
header('location:edit-source.php');
}else{
echo "Failed to update product<br/>";
}
}
?>
或者，我建议将其包装在一个函数中以使其可重用。
