人们对我上一个问题的建议似乎没有帮助。所以,我想在这里以完整的代码再次发布它:mysql_depriated.php:
<script>
function fun()
{
var ajaxRequest; // The variable that makes Ajax possible!
try{
// Opera 8.0+, Firefox, Safari
ajaxRequest = new XMLHttpRequest();
} catch (e){
// Internet Explorer Browsers
try{
ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try{
ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e){
// Something went wrong
alert("Your browser broke!");
return false;
}
}
}
var name = document.getElementById("name").value;
var url = "mysql_depricated2.php";
var param = "name=" + name;
ajaxRequest.open("POST", url, true);
//Send the proper header information along with the request
ajaxRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
ajaxRequest.setRequestHeader("Content-length", param.length);
ajaxRequest.setRequestHeader("Connection", "close");
ajaxRequest.send(param);
}
</script>
<input type="text" id="name">
<input type="button" value="ajax&" onclick="fun()">
mysql_depriated2:
<?php
$host="localhost"; // Host name
$username="root"; // Mysql username
$password=""; // Mysql password
$db_name="example"; // Database name
// Connect to server and select databse.
$con=mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
$content = $_POST['name'];
$content=mysql_real_escape_string($content);
$sql = "insert into e values('$content')";
mysql_query($sql);
?>
如果我尝试插入包含 & 符号的字符串,它将不起作用。请问有什么解决办法吗?
