janka Posted July 14, 2020 Report Share Posted July 14, 2020 Labdien, Izmantoju šādu skriptu, kas no saišu saraksta ģenerē dažas, kuras attēlot. <?php function dodosrandgen() { // set number of links you want to show at once $show_link = 2; // separate the links by, i.e. comma would be ","; $separator = " "; define('link', 'link'); define('priority', 'priority'); $links[0]['link'] = "<li><a href=\"http://www.delfi.lv/\">Delfi</a></li>"; $links[0]['priority'] = 5; $links[1]['link'] = "<li><a href=\"http://tvnet.lv/\">Tvnet</a></li>"; $links[1]['priority'] = 1; $links[2]['link'] = "<li><a href=\"http://php.lv\">Php</a></li>"; $links[2]['priority'] = 2; $links[3]['link'] = "<li><a href=\"http://apollo.lv/\">Apollo</a></li>"; $links[3]['priority'] = 3; $links[4]['link'] = "<li><a href=\"google.com/\">Google</a></li>"; $links[4]['priority'] = 4; // HERE COMES THE BODY if($links) { for($i = -1; $i < count($links); $i++) { for($j = 0; $j < $links[$i]['priority']; $j++) { $newlinksindex = count($newlinks) + 1; $newlinks[$newlinksindex] = $links[$i]['link']; } } } // end of if link exist // debug if($show_link >= count($newlinks)) $show_link = count($newlinks); $showarray[0] = ""; $showindex = 0; // Select a random element from the new array do { $randindex = rand(0, count($newlinks)); if(!in_array($newlinks[$randindex], $showarray) && $newlinks[$randindex] != "") { $showarray[$showindex] = $newlinks[$randindex]; //print_r($showarray); $showindex++; } }while(count($showarray) <= $show_link); // finally print out for($i = 0; $i < $show_link; $i++ ) { if($show_link == 1 || (($i + 1) == $show_link)) print $showarray[$i]; else print $showarray[$i].$separator; } //print_r($ranarray); //print_r($links); //print_r($newlinks); } // end of the dodosrandgen function ?> <?php dodosrandgen();?> Skriptam ir šādas problēmas: Quote Notice: Undefined offset: -1 in /home2/domain/public_html/a.php on line 28 Notice: Undefined variable: newlinks in /home2/domain/public_html/a.php.php on line 29 Paša mēģinājumi tās novērst noved pie vēl sliktāka iznākuma. Priecāšos par palīdzību. Paldies. Quote Link to comment Share on other sites More sharing options...
e-remit Posted July 14, 2020 Report Share Posted July 14, 2020 Kāpēc tev 27. rindā $i sāk skaitīt ar -1? Tak noticē teikts, ka 28. rindā mēģini masīvam dabūt elementu ar indeksu -1. Un otrajā noticē teikts, ka mēģini izmantot mainīgo, kurš nekur iepriekš nav definēts. Iesaku palasīt PHP manuāli par masīviem! Uzzināsi daudz jauna!
