PHP-s kuup\u00e4evadega t\u00f6\u00f6tamine on \u00fcks neist asjadest, millega te kas oskate h\u00e4sti, t\u00f6\u00f6tate selle m\u00f5istmise nimel v\u00f5i olete juhendis sisalduva dokumentatsiooni j\u00e4neseauku kinni j\u00e4\u00e4nud.<\/p>\n

Kui aga t\u00f6\u00f6tate WordPressiga, on t\u00f5en\u00e4osus, et peate kuup\u00e4evadega t\u00f6\u00f6tama, \u00fcsna suur. Peaaegu k\u00f5igel, mida avaldame, on seotud v\u00e4hemalt \u00fcks kuup\u00e4ev.<\/p>\n

See h\u00f5lmab postitusi, lehti, kohandatud postituste t\u00fc\u00fcpe, muudatusi, mustandeid ja nii edasi.<\/p>\n

Lisaks on t\u00f5en\u00e4oline, et kohandatud t\u00f6\u00f6, mida peate arendama, eeldab, et leiate PHP abil erinevuse kahe kuup\u00e4eva vahel. Ja kuigi selleks on mitu v\u00f5imalust, olen siiski j\u00e4rginud protsessi.<\/p>\n

PHP-i kasutavate kuup\u00e4evade erinevus<\/h2>\n

Enne kui ma oma n\u00e4ite l\u00e4bi l\u00e4hen, aitab see veidi konteksti anda. L\u00f5ppude l\u00f5puks on see, mille kallal te t\u00f6\u00f6tate, t\u00f5en\u00e4oliselt veidi erinev sellest, mida mina teen.<\/p>\n

\"Leidke<\/a><\/p>\n

\u00dcldine idee v\u00f5ib siiski olla sama, nii et teie tegevuse p\u00f5hiolemust saab siiski allolevast koodist ekstrapoleerida. Aga toon \u00fche konkreetse n\u00e4ite enda t\u00f6\u00f6st:<\/p>\n

    \n
  1. Mul on kohandatud postituse t\u00fc\u00fcp, mis t\u00e4histab s\u00fcndmust ja s\u00fcndmust postituskuup\u00e4evana.<\/li>\n
  2. Ma pean teadma, millal \u00fcritus algab. Selleks defineerin kuup\u00e4evavormingu, kasutades n\/j\/Y-vormingut, mida toetab PHP, ja teisendan selle kuup\u00e4evaks PHP kuup\u00e4evafunktsiooni<\/a> abil.<\/li>\n
  3. J\u00e4rgmiseks v\u00f5tan t\u00e4nase kuup\u00e4eva (lihtsa viisina selle n\u00e4ite puhul PHP abil kuup\u00e4evade erinevuse m\u00e4\u00e4ramiseks) ja teisendan selle kuup\u00e4evaks, kasutades sama funktsiooni ja n\/j\/Y vormingut.<\/li>\n
  4. P\u00e4rast seda loon kaks DateTime<\/a> objekti ja arvutan erinevuse.<\/li>\n<\/ol>\n

    Kui see pole lihtne, soovitan kl\u00f5psata \u00fclaltoodud linkidel. Muidu on kood siin<\/a>.<\/p>\n

    <?php\n\n\/**\n * Determines the number of years that exist between the specified\n * event custom post type and today's date.\n *\n * @access private\n * @param  WP_Post $event A custom post type representing an event.\n * @return string  $years The difference in years.\n *\/\nprivate function get_difference_in_dates( $event) {\n\n  \/\/ If the post_date is empty, why are we here?\n  if (empty( $event['post_date']) {\n    return;\n  }\n\n  \/\/ Get the date for the start of the event and te \n  $start = date( 'n\/j\/Y', strtotime( $event['post_date']) );\n  $today = date( 'n\/j\/Y' );\n\n  \/\/ Get the date for the start of the event and today's date.\n  $start      = new DateTime( $start );\n  $end        = new DateTime( $today );\n\n  \/\/ Now find the difference in years.\n  $difference = $start->diff( $end );\n  $years      = $difference->y;\n\n  \/\/ If the difference is less than one, we'll return a string of \"< 1\".\n  $years = (1 > $years )? '< 1': (string)$years;\n\n  return $years;\n}<\/code><\/pre>\n
    M\u00e4rkus \u00fclaltoodud koodis, et olen huvitatud ainult aastate erinevuse leidmisest. V\u00f5ite valida midagi muud. Kui see nii on, teeb PHP pakutav API seda h\u00f5lpsaks, uurides DateTime objekti<\/a> atribuute .<\/p>\n
    Kuid arvestades kahte kuup\u00e4eva, on see lihtne viis kuup\u00e4evade erinevuse leidmiseks PHP-ga WordPressi kontekstis.<\/p>\n
