Katika somo hili utajifunza jinsi ambavyo utaweza kutengeneza mfumo wa kuisajiki na ku login, kisha kuangalia usalama wa mfumo kwa kuzuia sql injection.
Katika somo hili utakwenda kujifunza jinsi ya kuzuia injection. Nitakueleza jinsi ambavyo nimefanya mabadiliko ya kiusalama kutoka kwenye somo lililotangulia. Hivyo basi hakikisha umelielewa vyema somo lililotangulia pia uwe umefanyia mazoezi.
MABADILIKO YA KIUSALAMA:-
Katika kujisajili
Kwenye login na register form nimeongeza kipengele cha required maana yake kama atatuma empty form itakataa. N ahata akituma kwenye php code hataona chochote maana tumetumia isset() na empty() tulisha jifunza kuhusu isset() function na inavyofanya kazi. Hi ya empty ni sawa na hii isset.
Atakapoanza kujisajili na kutuma data kwanza zitakaguliwa kama ni empty hatapata action yeyote. Endao data zitakuwa zipo kwanza zitaangaliwa ni lazima jina liwe na angalau character 4 kama ni chini ya hapo atapata meseji itakayimtaka aoneze caracter kwenye jina. Endapo jitakuwa ni zaidi ya 4hatuw aitakayofuata ni kuangalia kama password ina character kuanzia 6, endapo zipo chini ya hapo atapata meseji inayomtaka aongeze character.
Endapo zitakuwa kuanzia 6 hatuwa inayofuata ni kuangalia kama email ina character kuanzia 8, endapo zitakuwa pungufu ya hizo atapata ujumbe unaomtaka arekebishe email yake. Endapo zitakuwa kuaznia 8 hatuwa inayofuata ni ku sanitize email.
Tunafanya sanitizing ili kuondoa code ambazo zipo kwenye email ambazo zinaweza kufanya injection. Endapo itafaulu kwenye sanitizing itafanyiwa validation kuona kweli ni email iliyo sawa kimpangilio. Endapo itafeli kwenye validation na sanitizing atapata ujumbe unaohitaji kuangalia vyema email.
Baada ya kukamilika uchunguzi wa email hatuwa nyingine ya muhimu ni kuangalia je mtumiaji mwenye email kama hiyo yupo kwenye database. Endapo email hiyoimeshatumia kaba atapata ujumbe kuwa mtumiaji mwenye email hiyo yupo hivyo abadili email. Kufanya hivi tuta select count(id) ili kuangalia je kuna id ngap zenye email hiyo.kama jibu ni 0 maana yake hakuna hiyo email kwenye databse hivyo ataendelea na usajili. Kuhusu ku count() tulishajifunza kwenye mafunzo ya qsl level 1 na mafunzo ya php level 2.
Hatuwa inayofuata ni ku encrypt email baada ya kuwa ipo sawa. Tafadhali pitia somo la ku encrypt ili upate kuelewa vyema. Email ikiwa encrypted maana yake haitakuwa katika sura ya kawaida. Baada ya ku encrypt email sasa ni muda wa kucheza na jina. Nimeongeza mafaili mawili ya ecription na decription ili kupunguza kuandika code hizi kila sehemu. Kisha nime include mafaili hayo kila panapohitajika.
Jina nalo litapitia hatuwa kama hizo za kusanitize,na ku validate, kisha ku encrypt. Halafu na password yenyewe haina valifdation ili tutaifanyia hashing moja kwa moja. Tulisha zungumzzia somo hili kw aurefu zaidi. Katika njia zilizofundishwa hapa tutatumia password_hash().
Kipengele kilichoongezeka ni uniqu_id kwenye column za database. Tofauti na id kutakuwa na uniqu_id ambayo ni string zilizo hashed kwa kutumia sha1(). Hii itatusaidia katika ku view taarifa za user kuwa unique na sio rahisi kujuwa user mwingine.
Baada ya hapo tutatumia prepared query kusajili watumiaji wapya kwenye database. Endapo kila kitu kitakuwa sawa basi mtumiaji atapelekwa kwenye ukurasa wa ku login.
2. Katika ku login
Kama ilivyo kwenye html formkuna required ni lazima taarifa ziwe zimejazwa. Na hata kama hajajaza tumetumia isset() kuangalia kama ni empty
Bada ya hapo hatuwa ya kwanza ni ku sanitize jina na kuvalidate. Endapo itafeli atatakiwa kuangaliajian ikifanikiwa hatuwa ya pili ni ku encrypt jina. Tunafanya hivi ili kwamba tujeweza kulinganisha jina hili na lile ambalo tayari lipo kwenye databse ambalo nalo ni encrypted. Kwakuwa hatuhitaji email ku log in hivyo tumepunguza kazi.
Sasa tunatakiwa kwanza tuangalie je kwenye database tuna mtu ama watu wenye jina kama hilo. Kufanya hivi tutatumia count(id) ambazo zina jina kama hilo. Endapo jibu ni 0 maana yake mtumiaji huyo hayupo hivyo ahakikishe jina lake. Ikiwa jibu ni tofauti na 0 maana yke jina hilo lipo.
Hatuwa inayofuata ni kuhakikisha password. Kufanyanhivi kw akuwa ndia ya ku hash password tumetumia password_hash() basi ku verify tutatumia password_verify(). Tulisha jifunza habari hii kwenye masomoyaliopita. Endapo passowrd iliyokuwepo kwenye database ni sawa na password hii tulio ihash baada ya mtumiaji kuingiza zipo swa basi taanza ku start session, ili kwenda kwenye log in.
Ili kuanzisha session kuna faili jipya nimeongeza ambalo lina function ya kustart session. Faili hili nimeli include mwanzo mwa kila faili.tulisha jifunza kuhusu session katika masomoyaliopita. Session inabeba taarifa ambazo utahitaji zitumike kwenye page za website yako. Kwa mfano kubeba jina la mtumiaji popote alipo kwenye hiyo website. Session yetu hapo inabeba jina na id. Jina kwa ajili ya utambulishi na id kwa ajili ya ku view profile. Function ya kuanzisha session session_start()
Kila kitu kikiwa sawa atapelekwa kwenye dash boarda ambayo itamtambuwa kwa session ya jina lake. Kwenye dashboard hakuna mabadiliko makubwa sana. Ila kwa kuwa data zetu tume zi encrypt kwenye database basi hapa tutatikiwa ku decryp ili tuweze kuzisoma vinginevyo hatutazielewa.
Mabadiliko mengine yamefanyika kwenye view user kwenye dashboard yako. Kwanza nimetumia .htaccess faili ili kuondoa view.php?id=2 badala yake iwe /2 kisha baada ya kutumia id sasa nimetumia uniqu_id ambayo tumeingez akwenye databse. Hii itasaidia endapo umeshea profile ya mtu basi asiweze kujuwa pfrofile nyinginekwa kubadili id maaba kubadili uniqu_id na kupatia ni sawa na kugesi password.
JINSI YA KUANGALIA SESSION
Katika dashboard endapo mtu hajaloh in atakutana na ujumbe utakaomtaka a log in. hapi ni kwa kuwa kwanz atumeangalia je session ipo endapo sesstion ipo basi data zitaonekana vinginevyo ataambiwa login.
Kufanya hivi tutatumia isset() ambapo ndani yake tutaweka session yetu tuliokuja nayo kwenye login. Sasa ili kuangalia kama session haipo tutatumia ! kwa kuwa isset yenyewe inaangalia uwepo na ukiweka ! maana yake unaangalia kinyume chake. Hivyo tutasema endapo hakuna session basi log in vinginevyo onyesha data
if(!isset($_SESSION['username'])):?>
<b><a class="btn btn-primary btn-lg" href="login.php">Login</a></b>
<?php else: ?>
// hapa zinakaa code ambazo zitaonekana kama session ipo
Mwisho wa ambapo unahitaji data zionekane kwa mwene session utaeka <?php endif; ?>
Kumaanisha hapa ndipo mwisho wa condition yetu ya IF kwenye isset(). Kwa kufanya hivi pia utaweza kuchaguwa ni user gani aende kwenye page fulani. Kwa mfano unaweza anzisha session yenye user status, ukasema kama status ni 0 basi aende user page na endapo status ni 1 aende kwenye admin page
CODE ZOTE HIZI HAPA
Code nimezihost hapa unaweza kuipitia website ila hakikisha unapojisajili hautumii email yako ya ukweli maana hii ni kwa ajilii ya majaribio https://mafunzo-php.epizy.com/

MWISHO:
Na huu ndio mwisho wa course yetu ya mafunzo ya php level 3. Katika mafunzo haya tumefanikiwa kutengeneza blog pamoja na system ya ku log in na ku register. Kwenye project yetu kuu tutaunganisha system zote hizi mbili. Ila mpaka kufikia hapa coure imekamilika kwa neema za Mwenyezi Mungu. Mafunzo haya ni mwanzo tu kuna mengi tunahitaji kujifunza, ikiwepo ishu za security na kadhalika. Hivyo basi tuna nia ya kuendeleza course hii kwenye advanced php.
Je! umeipenda hii post?
