php - For loop to create extra columns -
this code displays basic tree structure bracket, trying complete following:-
where shows:
style="border-right:2px solid #000;"
i trying use border every row, script not create rows in between teams/seeds define border, trying show border-right every row every team 1 team 2 etc , other rounds team 1 team 2 etc.
php error reporting returning following line has undefined offset after
} else {?$line[$i] .= '<td align="center" style="border-right:2px solid #000;" colspan="2">vs</td>';3.
$array = array('team 1', 'team 2', 'team 3', 'team 4', 'team 5', 'team 6', 'team 7', 'team 8'); $j = count($array); ($a=0; pow(2, $a) <= $j; $a++) //determine highest power of 2 go array count { $y[$a] = 1; $maxpower = $a; } ($i=1; $i < $j*2; $i++) { if($i % 2 != 0) //odd number rows teams { $line[$i] = '<td class="pf_title_bg" style="border-right:2px solid #000;">' . $array[($i-1)/2] . '</td> <td class="pf_content_bg" style="border-right:2px solid #000;"> </td>'; } else { for($b=0; $b<=$maxpower; $b++) { $round = $b+1; $line2[$b] = ($b < $maxpower ? "<th colspan='2'>round {$round}</th>" : "<th colspan='2'>winner</th>"); if($i % pow(2, $b) == 0) //even rows future rounds. every 2^1 rows first winner, 2^2 second winner, 2^3 third , on. { if($i % pow(2, $b+1) != 0) //does not divide next power of 2, must last available cell { $line[$i] .= '<td class="pf_title_bg" style="border-right:2px solid #000;">team '.$b.'_'.($y[$b]++).'</td> <td class="pf_content_bg" style="border-right:2px solid #000;"> </td>'; } else //the input added in future round { $line[$i] .= '<td align="center" style="border-right:2px solid #000;" colspan="2">vs.</td>'; } } } } } //name="win'.$b.'_'.($y[$b]++).' eval ("\$content = \"".$this->gettemplate("table_header")."\";"); $content.="<thead><tr>"; foreach($line2 $col) { $content.=$col; } $content.="</tr></thead>"; foreach($line $row) { $content.="<tbody><tr>{$row}</tr></tbody>"; } eval ("\$content.= \"".$this->gettemplate("table_footer")."\";");
any on appreciated
you aren't constructing table correctly; putting tbody tag around every row, invaliding html. works me:
<?php $array = array('team 1', 'team 2', 'team 3', 'team 4', 'team 5', 'team 6', 'team 7', 'team 8'); $j = count($array); ($a=0; pow(2, $a) <= $j; $a++) //determine highest power of 2 go array count { $y[$a] = 1; $maxpower = $a; } ($i=1; $i < $j*2; $i++) { if($i % 2 != 0) //odd number rows teams { $line[$i] = '<td class="pf_title_bg" style="border-right:2px solid #000;">' . $array[($i-1)/2] . '</td>'.php_eol.'<td class="pf_content_bg" style="border-right:2px solid #000;"> </td>'.php_eol; } else { for($b=0; $b<=$maxpower; $b++) { $round = $b+1; $line2[$b] = $b < $maxpower ? "<th colspan='2'>round {$round}</th>".php_eol : "<th colspan='2'>winner</th>".php_eol; if($i % pow(2, $b) == 0) //even rows future rounds. every 2^1 rows first winner, 2^2 second winner, 2^3 third , on. { if($i % pow(2, $b+1) != 0) //does not divide next power of 2, must last available cell { $line[$i] .= '<td class="pf_title_bg" style="border-right:2px solid #000;">team '.$b.'_'.($y[$b]++).'</td>'.php_eol.'<td class="pf_content_bg" style="border-right:2px solid #000;"> </td>'; } else //the input added in future round { $line[$i] .= '<td align="center" style="border-right:2px solid #000;" colspan="2">vs.</td>'.php_eol; } } } } } //name="win'.$b.'_'.($y[$b]++).' //eval ("\$content = \"".$this->gettemplate("table_header")."\";"); $content="<table><thead><tr>"; foreach($line2 $col) { $content.=$col; } $content.="</tr></thead><tbody>".php_eol; foreach($line $row) { $content.="<tr>{$row}</tr>".php_eol; } $content.='</tbody></table>'; //eval ("\$content.= \"".$this->gettemplate("table_footer")."\";"); echo $content; ?>
