推荐答案
以下是您需要使用的代码:
Here is the code you need to use:
<?php
include("/connections/db_conx.php");
if(isset($_POST['submit'])) {
$title = mysqli_real_escape_string($db_conx, $_POST['title']);
$text = mysqli_real_escape_string($db_conx, $_POST['text']);
$picture = mysqli_real_escape_string($db_conx, $_POST['picture']);
$sql = "INSERT INTO news (`title`, `text`, `picture`) VALUES('$title','$text','$picture');";
if(!$result = $db_conx->query($sql)){
die('There was an error running the query [' . $db_conx->error . ']');
}
echo 'Entered into the news table';
}
?>
<html>
<head>
</head>
<body>
<form method="post" action="index.php" id="tech">
<table border="0">
<tr>
<td>Title</td>
<td> <input type="text" name="title"></td>
</tr>
<tr>
<td>Text</td>
<td><textarea rows="4" name="text" cols="50" name="comment" form="tech"> </textarea></td>
</tr>
<tr>
<td>Picture</td>
<td> <input type="varchar" name="picture"></td>
</tr>
<tr>
<td><input id="button" type="submit" name="submit" value="Submit"></td>
</tr>
</table>
</form>
</body>
</html>
您的问题是 mysqli_real_escape_string() 函数需要 2 个参数:数据库连接和要转义的字符串.
Your problem is that the mysqli_real_escape_string() function requires 2 parameters: the database connection, and the string to escape.
我还包括完全重新格式化的代码，以及错误检查.
I've also included completely reformatted code, and error checking as well.
