WordPress<\/a> on niin tehokas, koska voit kirjoittaa siihen laajennuksia. Laajennukset ovat hy\u00f6dyllisi\u00e4 hallinnassa, eiv\u00e4tk\u00e4 ne vaikuta, jos p\u00e4ivit\u00e4t\/vaihdat teemoja tai p\u00e4ivit\u00e4t WordPress-ytimi\u00e4. WordPress-laajennuksen kirjoittaminen on helppoa.<\/p>\n

Plugin-kansio<\/h3>\n

WordPress<\/a> -laajennukset tallennetaan kansioon \/wp-content\/plugins. Jokaisella laajennuksella on oma kansio. Liit\u00e4nn\u00e4isen<\/a> tulee olla php-tiedosto, jolla on sama nimi kuin kansiolla. Jos esimerkiksi annat kansion mallin nimeksi, sinun tulee luoda tiedosto sample.php kyseisen kansion alle.<\/p>\n

Plugin metatiedot<\/h3>\n

Jotta WordPress<\/a> ymm\u00e4rt\u00e4\u00e4 laajennuksen, sinun on laitettava kommentti laajennuksen php-tiedoston sis\u00e4\u00e4n (alkuun).<\/p>\n

T\u00e4m\u00e4n viestin<\/a> perusteella voimme luoda laajennuksen, joka est\u00e4\u00e4 useimmat roskapostikommentit tarkistamalla HTTP_REFERER<\/strong> – muuttujan.<\/p>\n

Miten se on parempi?<\/h3>\n
Voit helposti kytke\u00e4 laajennuksen p\u00e4\u00e4lle ja pois p\u00e4\u00e4lt\u00e4. Sinun ei tarvitse muokata suoraan funktiomallia (jos jokin menee pieleen, wordpress kuolee). Jos sotket laajennuksen, se yksinkertaisesti sammuu. Voit my\u00f6s p\u00e4ivitt\u00e4\u00e4 tietyn laajennuksen (helppo yll\u00e4pit\u00e4\u00e4).<\/p>\n
Sinun ei tarvitse tehd\u00e4 mit\u00e4\u00e4n, jos p\u00e4ivit\u00e4t wordpress- tai teematiedostot.<\/p>\n
