Kā phpmyadmin nomainīt max import file size? Faila lielumu. Kurš fails ir jārediģē un kas tieši?

April 23, 2009

Izdomāju ka vajag izveidot tā, ka atverot lapu ar datoru ir HTML layouts, bet verot vaļā ar mobīlā WAP'u ir WML... Viss takā jau jauki, bet kā lai izveido, ka veidojot lapu, kurā ir teikumi kas ir ielikti HTML "<p>" tagā normāli attēlojas uz WML? Dublēt info un katru likt savā layouts mapē nebūtu gudri, ne?

April 22, 2009

Centīšos, tikai gribēju pateikt ka šitas sviests ir manis veidots. :D

Paskaties core.php ko dara funkcija redirectTo! :)

Problēma tāda, ka ir header already send errors, bet nezinu kā sataisīt lai tas errors tur nebūtu... :(

April 22, 2009

Nu pagaidām viedoju tikai lai pamācītos PHP praksē, bet saksaros ar problēmu, ka nevaru sakarīgi lietotāju pēc reģistrācijas (signup.php) pārmest uz index.php.

P.S. Zinu ka līkaku sourci par šito nevar atrast, bet tikai mācos.

Problēma ir pavisam vienkārša. Ir galvenais fails (core.php), kurā ir norādīts "$rootPath" un "$stylePath".

$rootPath = $serverProtocol . "://" . $serverDirectory . "/" . $serverSubDirectory . "/";
$stylePath = $rootPath . "styles/" . $defaultStyle . "/";

Tad core.php ir iekļauts konfigurācijas fails.

$serverProtocol = 'http';
$serverDirectory = '127.0.0.1';
$serverSubDirectory = 'prototype';
$defaultStyle = "proLite";

Veidojot funkciju core.php failā - "overallHeader", dabūju šādu ķļudu.

Warning: require() [function.require]: URL file-access is disabled in the server configuration in D:\xampp\htdocs\prototype\includes\core.php on line 39

Warning: require(http://127.0.0.1/prototype/styles/proLite/overallHeader.php) [function.require]: failed to open stream: no suitable wrapper could be found in D:\xampp\htdocs\prototype\includes\core.php on line 39

Fatal error: require() [function.require]: Failed opening required 'http://127.0.0.1/prototype/styles/proLite/overallHeader.php' (include_path='.;D:\xampp\php\pear\') in D:\xampp\htdocs\prototype\includes\core.php on line 39

Funkcija izskatāš šāda.

function overallHeader($pageTitle = "")
{
global $alive, $siteTitle, $stylePath;

if(!$alive) {
	echo "Site is down for maintenance, please check back again later...";
	die;
}

if($pageTitle == "") {
	$pageTitle = $siteTitle;
}

header("Content-Type: text/html; charset=utf-8");

require $stylePath . "overallHeader.php";
}

Idejas? Vai norādīt "root" mainīgos savādāk, vai ieslēgt serveī tādu iespēju? ;?

March 23, 2009

Atvainojos ka nemeklēju... Paldies par risinājumu! :)

March 19, 2009

Problēma jau itkā nav problēma... :D

function redirectToIndex()
{
header('Location: index.php');
}

...un tur, kur vajag, lai lapa pārdirektējās, likt, lai izpildās šī funkcija...

Problēma!

Ko darīt, ja izmetas šāds "error's"?

Warning: Cannot modify header information - headers already sent by (output started at D:\xampp\htdocs\ProToType\styles\peace\overallHeader.php:4) in D:\xampp\htdocs\ProToType\includes\core.php on line 10

Nesaprotu kādēļ visu tā sarežģīt... Sākumā pastāsti, kam kods būs domāts?

March 18, 2009

Skaidrs, jau domāju, ka tieši tāda būs atbilde + paldies par iepriekšējo atbildi... ;)

March 18, 2009

Tas nu gan nav tiesa, Grey_Wolf. Gan ar include, gan ar require var dabūt return vērtību. Šajā ziņā abi strādā vienādi.

require no include atšķirība ir, ka pirmais izmetīs fatālu kļūdu, ja fails neeksistē. Otrais tikai warningu. Ko btw var visai skaidri izlasīt manuālī.

Te nu es tev nepiekrītu... Ja iekļauj jebko ar "include", tad ja kaut kas neeksistē, tad nekas neparādās - nereaģē, ber ar "require" izmet kļūdu...

Vai varbūt Es vienkārši nezinu kas ir "warning's" un kur to var redzēt? Ja nezinu, tad apgaismojiet mani... :D

March 18, 2009

Iedod kodu, lai palīdzētu izlabot... ;)

March 18, 2009

Tu jau bezproblēmām atrast "guglē" pamācību, kā pat nezinot PHP un MySQL pamatus izveidot tādu iespēju lapai, ka vari caur KP pievienot/rediģēt rakstus... ;)

March 17, 2009

Vai tad, loģiski nav tas, ka uzrakstot...

<?php

include 'example.txt';

?>

...man iekļauj vienu reizi failu "example.txt"...

Tad kāpēc ir "include_once", kura dara to pašu?! ;?

March 17, 2009

Nekas tā tev nesanāks... :( Tur vajag mainīt sesijas, apvienot datubāzes... :( Nav vienkāršāk parasto "phpBB" pārmodificēt ar dažām modifikācijām par tādu, kam ir "wordpress" iespējas?

Noderīgi resursi varētu būt - http://phpbb.com/ un http://phpbbgods.org/ ... ;)

March 17, 2009

Cik es sapratu, kad man skaidroja šīs lietas viens čalīts, tas sesijas id ("sid") normālās lapās aiz lapas linka vajadzētu padoties tikai tad, ja lietotājam ir izslēgti "cookies"... Un droši zinu, ka "cookies" nav tik droši kā sesijas, jo tos, pa visam vienkārši, var nozagt... :)

January 7, 2009

Šeit ir reģistrēšanās un ielogošanās sistēma, kurā ir daži "bugiņi", kā piemēram, ka nevar ielogoties [ :D ], un prasu jums, kā to varētu izlabot... Ceru, ka palīdzēsiet, jo viens pats to nevaru, jo ar PHP neesmu tik lielos draugos [ pagaidām ], tap\ec prasu jums... :) Kļūda ir tāda, ka ieejot /login.php, un savadot savus datus, izmet šādu kļūdu - There was an error: , please try again. !

Divi jautājumiņi...

P.S. zekils, tavs kods strādāja - paldies... :)

1) Ko es failā login.php uzrakstīju nepareizi, ka man met arā "erroru", lai gan viss pārējais strādā... ;)

login.php

<?php

require "includes/core.php";

stdhead("Ielogošanās");

if (isset($_GET['d']) and $_GET['d'] == "ok")
{

$dbname = "mysource";
$dbuser = "root";
$dbpass = "";

mysql_connect ( $dbhost, $dbuser, $dbpass)or die("Nevarēja piekonektēties: ".mysql_error());
mysql_select_db($dbname) or die(mysql_error());

session_start();
$nick = $_POST['nick'];
$pass = md5($_POST['pass']);

$query = "select * from users where nick='$nick' and pass='$pass'";

$result = mysql_query($query);

if (mysql_num_rows($result) != 1) {
 echo "Nepareiza info!";
}
else {
 $_SESSION['nick'] = "$nick";
 echo "Veiksmīgi!";
}

}

Met ārā šo...

2) Vai varu darīt šādi, un vai tas nekaitēs drošībai?

Tajās vietās kur ir dati par savienošanos ar db, izdarīt šādi...

require "includes/secrets.php"

P.S. Man inludes mapei ir htaccess, ka nevar tā pat piekļūt... ;)

December 23, 2008

Sapratu - izlaboju! :) Paldies...

Vai ir iespējams to take_x.php savienot ar x.php vienā failā?

December 22, 2008

Jā, kad piereģistrējos, tad DB parādās jauns ieraksts, bet kad mēģinu ielogoties, izlec - "Nepareiza info!"... ..., lai gan tā nav... :(

December 21, 2008

Labdien! PHP un MySQL tikai mācos, tapēc noteikti tur ir pilns ar kļūdām un citām sliktām lietām, bet vēlējos tomēr novērst šo ķibeli... :) Viss ar piereģistrēšanos strādā, bet ielogošanās gan nē... Par to atbild fails "take_login.php"... Kas tur par vainu? P.S. Tas nav mans kods, atradu kautkur netā, un centos pielabot...
