  4. Lapas aizsardzība pret uzhackošanu

    JL - izstrādes laikā jau par to ir jāparūējas.

     

    Visa veida saturs kas nāk POST / GET veidā servera apstrādē, tāpat arī REQUEST un URI_QUERY ir jāapstrādā korekti, tā lai šis saturs nebūtu valīds html, vai sql injection, vai nedod dievs pie eval šo saturu pielaist.

    Jānoslēdz visas brīvi pieejamās direktorijas, jāizvāc phpinfo fails, ja tāds ir.

     

    php expose vajadzētu atslēgt, aizslēgt openbasedir, izslēgt php safe mode,

    tā lai mums nebūtu šādi joki :)

    + veel 100 konfiguraciju kuras parasti tiek veiktas pie izstrades.

    ceru ka sapratu pareizi..

     

    labak lieto preg nevis str_rep

     

     

     

    $string = preg_replace("/\[b\](.*)\[\/b\]/Usi", "<b>\\1</b>", $string);
$string = preg_replace("/\[u\](.*)\[\/u\]/Usi", "<u>\\1</u>", $string);
$string = preg_replace("/\[i\](.*)\[\/i\]/Usi", "<i>\\1</i>", $string);
$string = preg_replace("/\[color=(\#[0-9A-F]{6}|[a-z]+)\](.*)\[\/color\]/Usi", "<span style=\"color:\\1\">\\2</span>", $string);
$string = preg_replace("/\[size=(.*)\](.*)\[\/size\]/Usi", "<span style=\"font-size:\\1ex\">\\2</span>", $string);
$string = preg_replace("/\[quote](.*)\[\/quote\]/Uis", "<div>Quote:</div><div style=\"border:solid 1px;\">\\1</div>", $string);
$string = preg_replace("/\[quote=(.*)](.*)\[\/quote\]/Uis", "<div>Quote from: \\1</div><div style=\"border:solid 1px;\">\\2</div>", $string);

  14. Php HELP

    in Iesācējiem

    Posted

    Nu kamdēļ ir jāraksta tik tizli, tak var arī sakārtot.

     

    <?php
$db = mysql_query("SELECT * FROM tabula LIMIT 1");
if(@mysql_num_rows($db)){
echo "Ir atgriezti rezultati";
}else{
echo "Nav atgriezti rezultati";
}
?>

     

     

    izmantojam @mysql_num... lai nebūtu kļūdu paziņojums gadijumā ja atgriezti 0 rezultāti.

     

    2 metode ir

     

    <?php
$db = mysql_query("select count(id) as cnt from tabula");
$db = mysql_fetch_object($db);

if($db->cnt>0){
echo "Ir atgriezti {$db->cnt} rezultati";
}else{
echo "Nav atgriezti rezultati";
}
?>

  20. Cookies

    in Javascript

    Posted · Edited by EdgarsA

    Ticu, daudziem būs noderīgi.

     

    Lūk kods kā apstrādāt (pievienot , lasīt , dzēst) cepumiņus ar Js palīdzību.

     

    function createCookie(name,value,days) {
if (days) {
	var date = new Date();
	date.setTime(date.getTime()+(days*24*60*60*1000));
	var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}

function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
	var c = ca[i];
	while (c.charAt(0)==' ') c = c.substring(1,c.length);
	if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
function eraseCookie(name) {
createCookie(name,"",-1);
}

  22. jQuery restrict element selection

    in Javascript

    Posted

    Sveiki forumieši.

     

    Situācija : Ir lapa, kurā ir daudz satura un daudz darba ar peli. Tā kā ši lapa ir interaktīva ar 90% js darbībām, ir nepieciešams izvairīties no vienas nianses, kura man personīgi krīt uz nerviem.

    Katru reizi, kad veidoju kaut kādus drag&drop vai vēl kaut ko kas ar peli saistīts, saskaros ar situāciju, ka nejauši trāpu citur, nevis uz kastes ko vēlos pārbīdīt, tad nu aiziet iezīmēšanās un tiek iezīmēti objekti.

     

    Gribētu izveidot kaut kāda veida event listener, kurš čekotu, gadijumā ja kaut kas tiek iezīmēts, kura typeof nav teksts, automātiski fokusēt body tagu lai viss iezīmētais attīrītos.

     

    Ceru ka mani sapratāt :)

     

    Lietoju jQuery.
