【问题描述】:
我在 index.php 中有一个表单 A,我需要将“notebook_id”的值传递给 create_new_note.php 中的表单 B。我使用 POST 方法来执行此操作,但它不起作用。
index.php 中的表单 A
<!-- Modal -->
<div class="modal" id="newNotebookModal" tabindex="-1" aria-labelledby="newNotebookModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<center><h5 class="modal-title" id="newNotebookModalLabel">Create a New Notebook</h5></center>
</div>
<div class="modal-body">
<form class="forms-sample" method="post">
<div class="form-group">
<label for="notebook_name_label">Notebook Name</label>
<input type="text" class="form-control" name="notebook_name" id="notebook_name" placeholder="Notebook Name">
</div>
</div>
<div class="modal-footer">
<button class="btn btn-outline-secondary btn-fw">Cancel</button>
<input type="submit" class="btn btn-primary" name="submit" value="Create"/>
</div>
</form>
</div>
</div>
</div>
</div>
表格 B
<form class="forms-sample" method="post">
<div class="form-group">
<label for="note_title_label">Title</label>
<input type="hidden" name="notebook_id" value="<?php echo $notebook_id; ?>">
<input type="text" class="form-control" name="note_title" id="note_title" placeholder="Title">
</div>
<div class="form-group">
<textarea class="form-control" name ="note_content"id="note_content" rows="40"></textarea>
</div>
<button class="btn btn-outline-secondary btn-fw">Cancel</button>
<input type="submit" class="btn btn-primary" name="submit" value="Create"/>
</form>
我使用 MVC 框架,因此这是我的控制器代码和模型代码
// Controller
function addNotebook($std_id) {
$notebook = new ManageNotesModel();
$notebook->std_id = $std_id;
$notebook->notebook_name = $_POST['notebook_name'];
if($notebook->addNotebook() > 0) {
$message = "Your notebook has been created!";
echo "<script type='text/javascript'>alert('$message');
window.location = '../ManageNotesView/create_new_note.php'</script>";
}
}
// Model
function addNotebook(){
$sql = "insert into notebook(std_id, notebook_name)values(:std_id, :notebook_name)";
$args = [':std_id'=> $this->std_id, ':notebook_name'=>$this->notebook_name];
$stmt = DB::run($sql, $args);
$count = $stmt->rowCount();
return $count;
}
请帮助我,我是新手,我试图通过它,但似乎无法弄清楚什么问题
