Question

正如标题所示我正在尝试将<select>中的值数组从视图传递到控制器以进行批量插入以下是视图类的部分片段：

       foreach($results as $row){echo '<tr>';       
    echo '<td> <select name="Select[]" value="'.$count.'" >
            <option value="Select">Select</option>}
             <option value="P">P</option>
             <option value="F">F</option>
            </select></td>';
    echo '<td> <select name="Select2[]" value="'.$count2.'" >
            <option value="Select">Select</option>}
             <option value="A">A</option>
             <option value="B">B</option>
             <option value="C">C</option>
             <option value="D">D</option>
             <option value="F">F</option>
            </select></td>';


    $count++;
    $count2++;
}

以下是控制器类的代码段：

$something = $this->input->post('select');
$something2 = $this->input->post('select2');
$classID = $this->input->post('classID');
$studentID = $this->input->post('studentID');
$count = 0;
$insertCount = 0;
$newEntries = array ();
$newRow = array (
    "employeeID" == $myID[0]->employeeID,
    "studentID" == $studentID[$count]->studentID,
    "type" == 'Midterm',
    "grade" == $something[$index[$count]],
    "classID" == $classID[$index[$count]]
);
die(print_r($newRow));
$newRow2 = array (
    "employeeID" == $myID[0]->employeeID,
    "studentID" == $classID[$index[$count]],
    "type" == 'Final',
    "grade" == $something2[$index[$count]],
    "classID" == $classID[$index[$count]]
);
$newEntries[$index[$insertCount]] == $newRow;
            $insertCount++;
$newEntries[$index[$insertCount]] == $newRow2;
$insertCount++;
$count++;
    }

所以问题是，对于班级和学生ID，它只将结果的最后结果传递回控制器。我现在可以忍受这个错误，但最重要的是，当这个运行时，$ something只包含值＆＃34; 1＆＃34;由die(print_r($something));

确定

Answer 1

要获得正确的结果，请使用标志TRUE

die(print_r($newRow, true));

print_r将返回值而不是将其打印到输出

将选择输入数组从视图传递到控制器（Codeigniter）
