Zvinhu zvakadai zvinoda kuti ari mhedziso, kunyange kana izvozvo zvinotora nguva. Kana iwe siya mukaha mumarudzi code, ipapo Server yenyu yose inogona kudzimika.

chengetedzo

With PHP faira Upload kuti Server rinoitwa zvikuru nyore. The code pfupi chaizvo uye nyore. Just kuchitsauko mitsetse. Zvisinei, nzira iyi ngozi. nguva yakawanda uye mitsetse remitemo kure kwakachengeteka.

The ngozi ndechokuti, kana iwe usingaiti inspections, chero vavashungurudza aigona Upload mumanyoro dzavo Server yenyu. Muchiitiko chino, zvichataurirana uoinde. Iye anogona kuita chero zvaanoda:

• Kudzima Database;
• zvinomuomera kuikanganwa mafaira Nzvimbo;
• nadzurudza mafaira Nzvimbo;
• wedzera AD wako website yako;
• Download nemavhairasi;
• Redirect vanozvishandisa zvose pamusoro nzvimbo dzavo;
• uye zvimwe zvinhu zvakawanda kuti kuuya mumusoro vavashungurudza.

Unofanira kugara tarisa kuti unoedza kukopa faira nokuda user. Somuenzaniso, kana iwe Upload mifananidzo chete, zvakakosha kuziva kuti faira chiri mufananidzo zvakarurama. Zvikasadaro, iwe uchava kukopa chinhu.

Tsoziva dzika ongororo, izvozvo kucharatidzwa, pamwe zvakananga kuongororwa manyorero kuti Upload mafaira.

Kutanga PHP fomu

faira Upload fomu iri nyore chaizvo. Kupotsa Browse bhatani uye Upload mabhatani.

Anotsanangura sei kuti pave siyana kwete, nokuti nyore. Mimwe mirayiridzo vanofungidzira kuti Matova dzinokosha Dzidziso HTML (mungadai haangavanzwi kutsvaga ruzivo pamusoro kudhanilodha pamusoro PHP).

Asi cherechedza kuti mashoko ari muchimiro unofanira kuwedzera enctype chizenga.

Zvikasadaro, mashoko ari faira Handler havazobvumirwi kutapukira.

Sei inofanira kushanda?

Kana iwe tinya Browse bhatani unofanira kuona bhokisi apo akakumbirwa kusarudza faira.

Pashure paizvozvo Richatsvakwa kugamuchira nzira apo faira iri.

Kana nzira hariwaniki, kuita chiito zvakare.

Pashure nekudzvanya pamusoro dhanilodhi faira Handler anogona kupa chero ruzivo.

Somuenzaniso, unogona kunyora mutsetse rinotaura kuti faira ndiye "saka uye saka" zita kwave zvinobudirira uploaded kuti forodha "dzakadaro". Chokwadi, faira zita achapiwa nguva dzose dzakasiyana.

Kazhinji, mashoko aya inoshandiswa debug yekubvuma. Saka zvinoita kuti azive kuti mashoko ari inoparadzirwa uye anonyora kuitika mune achida dhairetori. Kuti, kunyange faira zita hakuratidzwi. Sezvo mashoko aya imwe kuti inodzidzisa hakudi.

Zvine musoro goho zita chete kana inodzidzisa Downloads vakawanda mafaira. Zvakadaro, funga zvishoma mberi. Ngatiregei kuwana mberi kwedu.

Pano ndozvakanga fomu download faira, izvo zvinoratidza paunogumira uwandu ari uploaded faira.

PHP: faira Upload manyorero

Sezvo vose kuitwa tsika? In PHP faira Upload kunoitika kopi murayiro. Kana uchifarira mubvunzo sei download faira, mhinduro iri nyore copy-, iyo inoshandisa parameters maviri - panobva faira uye kuenda faira.

Asi, sezvo akataura pamusoro, harigoni mashoma zvokuzvidzivirira zvikonzero. Somuenzaniso, tarisa kuti faira mhando isu anotakura, unogona kushandisa munda mhando iri hondo $ _FILES. Chokutanga, ngationei kukurira rokuongorora, uye ipapo ita zvizere manyorero

Toti uchida kubvumira vanoshandisa Upload pikicha chete chisarudzo pamusoro GIF chete, jpeg kana PNG. Dzinoratidza zvinogona kuva saizvozvo.

kana ($ _ mafaira [ 'file_upload'] [ 'mhando']! = "mufananidzo / GIF") {

Kana uchida anotakura zvose 3 Marudzi, anongoti kuwedzera ezvinhu kune dzimwe mhando mufananidzo.

Kukopa zvinoitwa seizvi: kopi (mufananidzo 1, mufananidzo 2).

Kwatiri, kana basa iri kudhanilodha kubva PC kusvika Server, unogona kudaro
