我正在尝试通过 php-form 发布这 4 个文本字段,然后将其插入我的数据库中。
IBOutlet UITextField *who;
IBOutlet UITextField *what;
IBOutlet UITextField *where;
IBOutlet UITextField *contact;
Xcode中的post方法是:
- (IBAction)post:(id)sender
{
NSLog(@"%@", who);
NSLog(@"%@", what);
NSLog(@"%@", where);
NSLog(@"%@", contact);
// create string contains url address for php file, the file name is post.php, it receives parameter :name
NSString *strURL = [NSString stringWithFormat:@"http://website.com/post.php?who=%@&what=%@&where=%@&contact=%@",who, what, where, contact];
// to execute php code
NSData *dataURL = [NSData dataWithContentsOfURL:[NSURL URLWithString:strURL]];
// to receive the returend value
NSString *strResult = [[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding];
NSLog(@"%@", strResult);
}
我的 post.php 文件如下所示:
<?php header("Location: feed.php"); ?>
<?php
define ( 'DB_NAME','database_name');
define ( 'DB_USER','user');
define ( 'DB_PASSWORD','root');
define ( 'DB_HOST','localhost');
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if (!link) {
die('Could not connect: ' .mysql_error());
}
$db_selected = mysql_select_db(DB_NAME, $link);
if (!$db_selected) {
die('Can\'t use ' . DB_NAME . ': ' . mysql_error());
}
$value1 = $_REQUEST['who'];
$value2 = $_REQUEST['what'];
$value3 = $_REQUEST['where'];
$value4 = $_REQUEST['contact'];
$sql = mysql_query("INSERT INTO content VALUES ('','".mysql_real_escape_string($value1)."','".mysql_real_escape_string($value2)."', '".mysql_real_escape_string($value3)."','".mysql_real_escape_string($value4)."')") or die(mysql_error());
if (!mysql_query($sql)) {
die('Error: ' . mysql_error());
}
echo "You've just posted your text!";
mysql_close();
?>
但是当我尝试从应用程序发布时,没有任何反应......
