【问题描述】：
我正在尝试将表单数据提交到我的 MySQL 数据库，但是当我按下提交时，浏览器页面保持完全白色（错误报告已打开）并且没有数据提交到数据库，我的代码低于任何帮助将不胜感激： )
<?php
session_start();
include_once("db.php");
if(isset($_POST['widget_name']) && isset ($_POST['widget_type']) && isset ($_POST['language_support']) && isset ($_POST['widget_description']) && isset ($_POST['widget_dependencies'])){
if($_POST['widget_name'] != "" && $_POST['widget_type'] != "" && $_POST['language_support'] != "" && $_POST['widget_description'] != "" && $_POST['widget_dependencies'] != ""){
$name = $_POST['widget_name'];
$type = $_POST['widget_type'];
$language = $_POST['language_support'];
$description = $_POST['widget_description'];
$dependencies = $_POST['widget_dependencies'];
$sql_store = "INSERT INTO 'submissions' (ID, Author, Widget_Name, Widget_Type, Language_Support, Description, Dependencies, Icon) VALUES ('', '', '$name', '$type', '$language', '$description', '$dependencies', '')";
$sql = mysqli_query($db, $sql_store) or die(mysql_error());
} else {echo "<span class='enter-data' id='enter-data'>You need to enter data in all fields.</span>";}
} else {echo "<span></span>";}
/* if(isset($_POST['submit'])){
$iconName = mysql_real_escape_string($_FILES["image"]["name"]);
$iconData = mysql_real_escape_string(file_get_contents ($_FILES["image"]["tmp_name"]));
$imageType = mysql_real_escape_string($_FILES["image"]["type"]);
if(substr($imageType,0,5) == "image"){
mysqli_query("INSERT INTO 'submissions' VALUES('','$ImageName','$imageData') ")
} else {echo "Only images allowed.";}
} */

【问题讨论】：
-
空白页表示您有错误。查找您的错误日志/启用错误报告并阅读它们。
-
另外，您正在为您的 id 列添加 empty('') 。你确定这是对的吗？
-
or die(mysql_error())错误有两个原因。
