Tofu pehea ki te whakatinana i whakaū, ka kia whakaaturia ai, ki te hōtuhi whakamātautau hāngai ki te tukuake kōnae.

Te hanga i te puka PHP

Ko te tino māmā puka tukuake kōnae. E ngaro ana i te pātene tirotiro me te tukuake pātene.

Whakaahua ana pehea ki te waihanga e kore e puka, no te mea te reira ngāwari. tohutohu atu amo e kē koe i te ariā taketake o te HTML (te kore e kore e te rapu koe mo te mōhiohio e pā ana te tikiake i runga i PHP).

Ko te tohu ia i nga raraunga i roto i te puka e hiahia ana koe ki te tāpiri i te huanga enctype.

Kore, e kore e e tuku raraunga i runga i pūnanao kōnae.

Me pehea kia mahi i te reira?

A, no te pāwhiri koe i runga i te pātene tirotiro kia kite koe i te pouaka i reira ka ui ki te whiriwhiri i te kōnae.

I muri e ka hiahiatia kia reira ki te farii i te ara i reira kei te kōnae te.

Ki te kore e puta i te ara, te mahi ano te mahi.

I muri te pāwhiri i runga i te pūraweke kōnae download taea te hoatu i tetahi mōhiohio.

Hei tauira, ka taea e koe te tuhituhi te rārangi e kī e te kōnae ko "na me pera" kua pai te tukuake ki te kōpaki "taua, me te taua" te ingoa. O te akoranga, ka hoatu rerekē tonu te ingoa kōnae.

Tikanga, Kei te whakamahia tenei mōhiohio ki te waehere patuiro. Ko te kupu he reira taea ki te manatoko i tuku te raraunga kei te me tuhi puta i roto i te whaiaronga e hiahiatia ana. E te, e kore te ara te ingoa kōnae tohua. Mai tenei mōhiohio anō e kore e hiahia ana i te kaiwhakamahi.

Hanga ana te reira tikanga ki putanga te ingoa anake, ki te tikiake i te kaiwhakamahi kōnae maha. He pera ano te take, whakaaro he iti atu. Kei a kore whiwhi mua o tatou.

whakatikatikanga

I roto i te PHP kōnae tukuatu ki te tūmau titau etahi tautuhinga, e kia mahia i roto i te kōnae php.ini. Kei roto i tēnei kōnae i te rota o tautuhinga. Ratou katoa e kore matou e hiahia ana. He hiahia i roto i ngā rārangi e toru matou: file_uploads, upload_tmp_dir me upload_max_filesize.

Me mōhio e ka pā enei tautuhinga katoa o koutou pae i runga i te tūmau, e kore noa tetahi i tetahi. Na reira, ki te whakaturia te rahi mōrahi e hāngai ana i runga i te meka e ka whai ki te uta i ngā kaiwhakamahi koe. E kore e tūtohu ana ki te whakaturia nui rawa.

Kia huri koe i te uara i roto i enei tawhā, e hiahia ana koe ki te tīmata anō te tūmau. Kore e kore te tautuhinga e tango pānga, pera lau ratou i te wa o te kawenga tūmau.

Ka taea e te mahi koe i tenei i roto i te papatohu mā te tūhono mā SSH ki te tūmau. tomo noa i te HTTPD tīmata whakahau ratonga, a ka ka tango i te tautuhinga pānga.

Ko tētahi atu tikanga - he tīmata i roto i ISP-rōpū i roto i kaiwhakarato rōpū nama ranei.

kōnae ngohi

I roto i te PHP mahi tukunga kōnae e te ngohi $ _ngā kōnae. Kei te reira i te mōhiohio katoa e pā ana ki te kōnae e tiki tatou.

Hei kite i te aha ngā mōhiohio i roto i roto i te ngohi, nui ki te tuhituhi i roto i te pūnanao kōnae e whai ake nei.

Tīpakohia tetahi kōnae, me te pāwhiri "Tukuatu." I te whārangi pūraweke ka whakaatu i te mōhiohio rongoa e te i $ _ngā kōnae. Kei te katoa te tāupe tuhituhi ki reta whakapaipai. PHP - he reo-tairongo.

Ka rite ki a koutou e taea te kite, i roto i tenei ngohi he rota o mara. He nui ki a tatou katoa o ratou. Kei roto i te mara tuatahi te ingoa kōnae i roto i te puka i roto i nei te whakamahia ai i runga i tō rorohiko.

tohua te momo tīwae momo kōnae. hāngai Tmp_name mara ki te ingoa o te kōnae rangitahi. I muri i te mutunga o te hōtuhi ka mukua.

Kei roto i te mara hapa te waehere hapa. Ko te iti atu tenei. Rahi - te rahi i roto i paita.

hapa

Kawea atu i roto i te tukunga kōnae PHP e haere tahi tonu e te waehere hapa. He karere hapa tomo i roto i te "hapa". Ko te hapa screenshot ko te kore.

A feruri i te uara o nga hapa katoa:

I mea te reira i runga ake e pā ana ki te tawhā e taea te tohua i roto i te HTML mua.

Tenei ko te puka tauira ki te tikiake i te kōnae, e tohu te rohe o te nui o te kōnae tukuake.

hōtuhi tukunga kōnae: PHP

Ka rite ki te katoa kawea atu i roto i te mahi? I roto i te PHP puta whakahau tārua tukuake kōnae. Ki te hiahia i roto i te pātai o te pehea, ki te tikiake i te kōnae koutou, te whakahoki, ko te copy- ohie, e whakamahi ana e rua tawhā - te kōnae pūtake me te kōnae ūnga.

Ko, rite kī i runga, e kore e taea e te mea iti no te mau tumu haumaru. Hei tauira, tirohia i roto i te mea ahua o kōnae kaipuke matou, ka taea e koe te whakamahi i te momo mara i roto i te ngohi $ _ngā kōnae. Tuatahi, kia mahi a ki tirohanga, a ka neke ki runga ki te hōtuhi tonu

Kia mea a e hiahia ana koe ki te tuku i ngā kaiwhakamahi ki te tukuake i te whakaahua ki te taumira o anake GIF, JPEG teitei ranei. Tohua taea e te reira rite tenei.

ki te ($ _ KŌNAE [ 'file_upload'] [ 'momo']! = "image / gif") {
fakaongo "Aroha mai, tautoko tatou tikiake Gif-Kōnae anake";
putanga;
}

Ki te hiahia koe ki te kaipuke katoa 3 momo, tāpiri noa te huru atu ki te tahi atu momo o te whakapakoko.

mahi Tārua te rite tenei: tārua (image 1, image 2).

I roto i to tatou take, ka te tikiake i te mahi i te PC ki te tūmau, ka taea e rave i te reira koe

tārua ($ _ KŌNAE [ 'file_upload'] [ "tmp_name"], "1.jpg")

Ko, ka tāruatia te kōnae ki te ingoa 1.jpg. e kore te mea tika katoa tenei. I roto i tenei take, ko reira anake te tauira. He tika tonu te ingoa kōnae ki te tautuhi rerekē, ka whakapūtā te toronga, i runga i te kōnae rānei.

Whakatau e taea te toronga hei huarahi rerekē. Te reira i katoa tei runga i te kaiwhakawhanake o te mōhiotanga,. Ko tētahi o nga ara tere ki (te rerekētanga o whakatekau o hēkona) whakatau i te toronga - ko te waehere muri tenei.

$ Path_info = pathinfo ($ _ KŌNAE [ 'photo1'] [ "ingoa"]);

$ Pūriki = $ path_info [ 'toronga'];

Ko te tāupe $ te ext ka rokiroki tatou te toronga e hiahiatia ana. Ka taea te whakaturia te ingoa kōnae i md5 te whakamahi i tupurangi. Ki te whakamahere koe ki te tiki i te rota o ngā kōnae, he pai ki te kaipuke a ratou ki kōpaki rerekē. Na ka waiho te reira atu watea. I roto i ngā, ki te hiahia koe ki te e pokekore ai.

ki te tiki i te waehere e kia e whai ake.

kōnae maha

Tukuatu kōnae maha (PHP) puta i te tikanga o ngā āpure atu i roto i te puka.

e kore he tino pai tenei tikanga, kia rite ki tauwhāiti reira te maha o ngā kōnae ki te tiki. Ano, kua whakaaro te reira i puka kino i roto i te hōtaka. Whakamātauria ki te mahi i nga mea katoa hihiri.

Ko te kōwhiringa pai - ko reira he pai rawa o te tau nui o ngā kōnae i kotahi mā te pēhi i te pātene kotahi.

Ki te mahi i tenei, te hanga i tētahi āhua rite tenei waehere.

Hei whakamātau i taea te whakamahi i ano te var_dump ($ _ KŌNAE);

Ka koutou kōnae katoa kia whakanohoia i roto i te ngohi rite tenei:
