如何將值傳遞到phpmyadmin數據庫？

Question

如題

這是我的代碼

文件

#define kPostURL @"http://localhost/discuss.php"
#define kName @"name"
#define kMessage @"message"
#define kNum @"num"

@interface TestDisViewController : UIViewController{

IBOutlet UITextField *nameText;
IBOutlet UITextView *messageText;
NSURLConnection *postConnection;

UILabel *bbb;
}

@property(strong, nonatomic)IBOutlet UILabel *bbb;
-(IBAction)post:(id)sender;
@property(weak) NSString *aaa;

@end

---

和m.file

“ aaa”是從另一個視圖控制器中選擇的字符串

#import "TestDisViewController.h"
#import "EatDiscussViewController.h"
@implementation TestDisViewController

@synthesize aaa;
@synthesize bbb =bbb;


-(void) postMessage:(NSString*) message Name:(NSString *) name withNum:(NSString *) num{


if (name != nil && message != nil  && num != nil){

    NSMutableString *postString = [NSMutableString stringWithString:kPostURL];
    [postString appendString:[NSString stringWithFormat:@"?%@=%@", kName, name]];
    [postString appendString:[NSString stringWithFormat:@"&%@=%@", kMessage, message]];
    [postString appendString:[NSString stringWithFormat:@"#%@=%@", kNum, num]];
    [postString setString:[postString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:postString]];
    [request setHTTPMethod:@"POST"];
    postConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];

}

- (void)viewDidLoad
{
[super viewDidLoad];
NSLog(@"Taaaaaaaaab:%@",aaa);
self.bbb.text=aaa;
}

}

-(IBAction)post:(id)sender{

[self postMessage:messageText.text Name:nameText.text withNum:bbb.text];
[messageText resignFirstResponder];
messageText.text = nil;
nameText.text = nil;
bbb.text=nil;
[self.navigationController popViewControllerAnimated:YES];

}

@end

我刪除了一些不需要使用的代碼〜

最后是我的php.code

---

@mysql_select_db($database) or die("Error");

$user_name = $_GET["name"];

$commentary = $_GET["message"];

$stores_num = $_GET["num"];

$query = "INSERT INTO comment VALUES ('', '$stores_num' , '$user_name' , '$commentary')";

mysql_query("SET NAMES 'utf8'");

mysql_query($query) or die (mysql_error("error"));

mysql_close();

---

我可以將兩個值傳遞給數據庫

但我不能傳遞三個值........

請幫助我！

Answer 1

錯誤：[postString appendString：[NSString stringWithFormat：@“＃％@ =％@”，kNum，num]];

修復：[postString appendString：[NSString stringWithFormat：@“＆％@ =％@”，kNum，num]];

Answer 2

$user_name = $_GET["name"]; 
$commentary = $_GET["message"]; 
$stores_num = $_GET["num"]; 

$query = "INSERT INTO comment VALUES ('', '$stores_num' , '$user_name' , '$commentary')"

如果您沒有在查詢中列出這些字段，則不一定按照您期望的順序添加它們； 嘗試顯式添加字段名稱：

$query = "INSERT INTO comment (num, stores_num, user_name, commentary) VALUES ('', '$stores_num' , '$user_name' , '$commentary')"

如果num是一個自動遞增的字段，則您甚至不需要：

$query = "INSERT INTO comment (stores_num, user_name, commentary) VALUES ('$stores_num' , '$user_name' , '$commentary')"

然而

您正在使用mysql_*函數，而這些函數已被棄用。 您應該考慮使用PDO或mysqli_它們都將幫助您編寫更安全的代碼。
