I have done this several times before but for some reason I can't get the post to go through... I tried the php script with the variables set to _POST and without... When they aren't set to post it works fine. Here is my iOS code:
NSDate *workingTill = timePicker.date;
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"HH:mm"];
NSString *time = [formatter stringFromDate:workingTill];
NSString *post = [NSString stringWithFormat:@"shift=%@&username=%@", time, usernameString];
NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:NO];
NSString *postLength = [NSString stringWithFormat:@"%d", [post length]];
NSURL *url = [NSURL URLWithString:@"http://wowow.php"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
[request setHTTPMethod:@"POST"];
NSLog(@"%@", post);
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody:postData];
[NSURLConnection connectionWithRequest:request delegate:nil];
[self.navigationController popToRootViewControllerAnimated:YES];
And here is a chunk of the php, are the POST variables not in the right location?
<?php
function objectsIntoArray($arrObjData, $arrSkipIndices = array())
{
$arrData = array();
// if input is object, convert into array
if (is_object($arrObjData)) {
$arrObjData = get_object_vars($arrObjData);
}
if (is_array($arrObjData)) {
foreach ($arrObjData as $index => $value) {
if (is_object($value) || is_array($value)) {
$value = objectsIntoArray($value, $arrSkipIndices); // recursive call
}
if (in_array($index, $arrSkipIndices)) {
continue;
}
$arrData[$index] = $value;
}
}
return $arrData;
}
$newShift = $_POST('shift');
$bartenderUsername = $_POST('username');
mysql_connect("host", "name", "pw") or die(mysql_error());
mysql_select_db("harring4") or die(mysql_error());
$result = mysql_query("SELECT * FROM BartenderTable WHERE username='".$bartenderUsername."'") or die(mysql_error());
$row = mysql_fetch_array($result);
$newfname = $row['fname'];
I imagine this is a rather simple answer to a more experience developer, thanks for your help!
$_POST
is an array, not a function. You need square brackets to access array indices:
$newShift = $_POST['shift'];
$bartenderUsername = $_POST['username'];
Use following code. make sure that post string's receipt is a key and will be used in server. client side code
NSString *receipt1 = @"username";
NSString *post =[NSString stringWithFormat:@"receipt=%@",receipt1];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:@"http://localhost:8888/validateaction.php"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];
NSHTTPURLResponse* urlResponse = nil;
NSError *error = [[NSError alloc] init];
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error];
NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(@"Response Code: %d", [urlResponse statusCode]);
if ([urlResponse statusCode] >= 200 && [urlResponse statusCode] < 300)
{
NSLog(@"Response: %@", result);
}
}
server side php script.
validation.php
<?php
if(_POST)
{
if($_POST['receipt'] == 'username')
{
echo "post successfull";
$receipt = $_POST['key1'];
echo $receipt;
}
else
{
echo "not post";
}
?>
