使用codeigniter对列表中的单个项目进行评级
我想知道如何在项目列表中发布单个项目的评级，
这个代码让我为多个项目评分，但不是单个项目：
for($i=0;$i<2;$i++){
$doc_item_id = $_POST['item_id0'][$i];
$doc_rating = $_POST['document_rating'][$i];
$it_rt = array(
'item_id' => $doc_item_id,
'rating' => $doc_rating,
);
$this->purchases_model->update_document($it_rt);
}
foreach($_POST['item_id0'] as $doc_item_id){
foreach($_POST['document_rating'] as $doc_rating){
}
break;
}
$it_rt = array(
'item_id' => $doc_item_id,
'rating' => $doc_rating,
);
$this->purchases_model->update_document($it_rt);

$i = $_POST['item_index']; // Here I'm supposing that you have added radio buttons // named 'item_index' to allow user to choose the item to rate $doc_item_id = $_POST['item_id0'][$i]; $doc_rating = $_POST['document_rating'][$i] ; $it_rt = array( 'item_id'=> $doc_item_id, 'rating' => $doc_rating, ); $this->purchases_model->update_document($it_rt);循环的原始代码。吠强祷豪硅
$last=true; // false for first if($last){ $id=end($_POST['item_id0']); }else{ $id=reset($_POST['item_id0']); } // alternative: $id=($last)?end($_POST['item_id0']):reset($_POST['item_id0']); // test id if($id===false){ // no item was supplied } if(!isset($_POST['document_rating'][$id])){ // somehow, the item id doesn't have a matching document rating } // everything is okay! $doc_item_id = $_POST['item_id0'][$id]; $doc_rating = $_POST['document_rating'][$id]; $it_rt = array( 'item_id' => $doc_item_id, 'rating' => $doc_rating, ); $this->purchases_model->update_document($it_rt);
