如何在id
数组的每次迭代中使用check_seeds
并将每个事件添加到seeded[]
数组中。
更简单地说,我想从第一次迭代中获取一个项目并添加到第一次迭代中,从第二次迭代中获取一个项目并添加到第二次迭代中,依此类推...
实际上,在update_batch上,我们需要第三个参数(主键,索引)来更新数据库行中的数组值,其中数据库行中的id
与id
中的update_batch
相匹配。
$check_seeds = $this->tournament_model->get_seeds($tournament_id);
$seeds = $this->input->post('seed');
foreach ($seeds as $key => $value){
if(!empty($key) && !empty($value)){
$seeded[] = array(
'id' => (Add id here),
'tournament_id' => $tournament_id,
'stage_id' => $stage_id,
'seed_id' => $value,
'team_name' => $key,
);
$this->db->update_batch('tournament_seed', $seeded, 'id');
redirect('organizer/tournaments);
}
}
print_r($ check_seeds)
Array
(
[0] => Array
(
[id] => 3
[tournament_id] => 713161746
[stage_id] => 3
[seed_id] => 3
[team_name] => -V-ATTAX
)
[1] => Array
(
[id] => 4
[tournament_id] => 713161746
[stage_id] => 3
[seed_id] => 3
[team_name] => -V-ATTAX
)
[2] => Array
(
[id] => 5
[tournament_id] => 713161746
[stage_id] => 3
[seed_id] => 3
[team_name] => -V-ATTAX
)
)

在模型函数get_seeds()中,您可以查询id的当前最大值作为别名,并将其与查询结果一起返回:
i1 <- text_table[, Reduce(`+`, lapply(text_patterns,
function(x) str_detect(text, x))) >1]
text_table[i1]
# ID text
#1: 1 lucy, sarah and paul live on the same street
#2: 3 lucy and sarah are cousins
然后在控制器的for_each()中增加该值:
function get_seeds($tournament_id) {
$this->db->select_max('id', 'max_id');
$this->db->where('tournament_id', $tournament_id);
$result = $this->db->get('tournament_seed');
return $result->result();
}
