Php 从表中获取值并将该值提交到另一个表_Php_Mysql

Php 从表中获取值并将该值提交到另一个表

php mysql

Php 从表中获取值并将该值提交到另一个表,php,mysql,Php,Mysql,所以我想从表单（而不是填充表单）向数据库表输入数据。之后，我想将输入匹配到某个表（表A），以获得输入数据的id。然后我想把这个id插入到另一个表中 <?php //submit attendance mahasiswa if(isset($_POST['buttonSubmitAbsenMahasiswa'])){ foreach($_POST['inputStatusAbsen'] as $id_absensi=>$status_absensi){

所以我想从表单（而不是填充表单）向数据库表输入数据。之后，我想将输入匹配到某个表（表A），以获得输入数据的id。然后我想把这个id插入到另一个表中

<?php    
//submit attendance mahasiswa
    if(isset($_POST['buttonSubmitAbsenMahasiswa'])){

        foreach($_POST['inputStatusAbsen'] as $id_absensi=>$status_absensi){
            $id_mahasiswa = $_POST['inputHiddenIDMahasiswa'][$id_absensi];
            $nim_mahasiswa = $_POST['inputHiddenNIMMahasiswa'][$id_absensi];
            $nama_mahasiswa = $_POST['inputHiddenNamaMahasiswa'][$id_absensi];
            $nama_matakuliah = $_POST['inputHiddenMataKuliahMahasiswa'][$id_absensi];
            $tanggal_absensi = date("Y-m-d");       

            //get matakuliah id
            $class_query = "SELECT * FROM matakuliah WHERE nama_matakuliah='".$nama_matakuliah."'";
            $class_id = mysqli_query($connection, $class_query);

            if($class_id){
                while($class_id1 = $class_id->fetch_assoc()){
                    $class_id_fin = $class_id1['id_matakuliah'];
                }
            }

            //get mahasiswa id
            $student_query = "SELECT * FROM data_mahasiswa WHERE nama_mahasiswa='".$nama_mahasiswa."'";
            $student_id = mysqli_query($connection, $student_query);

            if($student_id) {
                while ($student_id1 = $student_id->fetch_assoc()) {
                    $student_id_fin = $student_id1['id_mahasiswa'];
                }
            }

            //insert or update the record
            $query_insert_data_absensi = "INSERT INTO data_absensi VALUES ('$class_id_fin' , '$student_id_fin' , '$tanggal_absensi' , '$status_absensi')";

            mysqli_query($connection, $query_insert_data_absensi);
        }
    }
?>

或在此：

CREATE TABLE matakuliah(
id_matakuliah int(255) PRIMARY KEY AUTO_INCREMENT,
nama_matakuliah varchar(255));

这样我就可以得到对应表的id

然后我想将id插入到：

CREATE TABLE data_absensi(
id_absensi int(255) PRIMARY KEY AUTO_INCREMENT,
id_mahasiswa int(255),
id_matakuliah int(255),
tanggal_absensi date,
status_absensi varchar(255));

输入如下：

  <td>
    <?php echo $class['id_mahasiswa']; ?>
    <input type="text" hidden value="<?php echo $class['id_mahasiswa']; ?>" id="inputHiddenIDMahasiswa" name="inputHiddenIDMahasiswa[<?php echo $i; ?>]">
