我写了一个脚本,允许我很好地添加房间名称,描述等。它使用jquery自动保存并附加额外的表单。除了我尝试使用<input type="file">
时,这一切都非常完美。我并不特别想使用已经存在的插件,因为当我单击save /自动保存被触发时,可见表单中的所有数据都会使用php和mysqli自动保存或更新到数据库中,然后返回每个插入ID,这一点很重要打破,并使用插件可能会破坏我的系统,因为它的工作方式我现在需要它。
理想情况下,我想在保存到数据库的每个表单的每个文件输入中实现相关文件名,就像其他表单信息一样,然后触发上传到文件夹。我希望我能尽力解释这一点,这有点令人困惑
以下是我的所有相关代码。如果你能摆脱任何光明,我将非常感激!
表单页面:
<body>
<div id="formHolder">
<div class="addItem">
<form method="post" action="add_room.php">
<label for="itemName[]">Item</label>
<input type="text" name="itemName[]">
<label for="itemCondition[]">Condition</label>
<input type="text" name="itemCondition[]">
<input type="file" name="itemPhoto[]">
<input type="hidden" name="itemId[]" value="">
<input type="hidden" name="itemParent[]" value="<?=$_GET['room']?>">
<div class="saveIcon" style="display: none; color: green;">SAVED!</div>
<div class="save">Save Item</div>
</form>
</div>
</div>
<div id="addForm">Add another room</div>
<br><br>
<div id="message"></div>
</body>
jQuery的:
<script>
function postForm(form) {
var $this = $(form);
var string = $this.serialize();
$.ajax({
type: "POST",
url: "add_room.php",
data: string,
cache: false,
success: function(data){
var saveIcon = $this.find('.saveIcon');
$this.find('[type=hidden]').val(data);
saveIcon.fadeIn(750);
saveIcon.delay(500).fadeOut(750);
$('#message').text('The id of the inserted information is ' + data);
}
});
}
function autosave() {
$('form').each(function() {
postForm(this);
});
}
setInterval(autosave, 10 * 1000);
$(document).ready(function() {
$('body').on('click', '.save', function(e) {
postForm($(this).closest('form').get(0));
});
$('#addForm').on('click', function(){
$('<form method="post" action="add_room.php"><label for="itemName[]">Item</label><input type="text" name="itemName[]"><label for="itemCondition[]">Condition</label><input type="text" name="itemConition[]"><input type="file" name="itemPhoto[]"><input type="hidden" name="itemId[]" value=""><input type="hidden" name="itemParent[]" value="<?=$_GET["room"]?>"><div class="saveIcon" style="display: none; color: green;">SAVED!</div><div class="save">Save Item</div></form>').fadeIn(500).appendTo('.addItem');
});
});
</script>
PHP:
<?PHP
require_once('dbConfig.php');
$item = $_POST['itemName'];
$condition = $_POST['itemCondition'];
$photo = $_POST['itemPhoto'];
$id = $_POST['itemId'];
$parentId = $_POST['itemParent'];
foreach($item as $key => $val) {
if(!$id[$key]) {
if ($stmt = $db->prepare("INSERT test (test_title, test_desc, test_parent, test_photo) VALUES (?, ?, ?, ?)"))
{
// Use an s per variable passed to the string, example - "ss", $firstname, $lastname
$stmt->bind_param("ssis", $val, $condition[$key], $parentId[$key], $photo[$key]);
$stmt->execute();
$stmt->close();
echo $db->insert_id;
//echo "success";
}
// show an error if the query has an error
else
{
echo "ERROR: Could not prepare Insert SQL statement.";
}
}
else
{

$stmt->bind_param("ssi", $val, $photo[$key], $id[$key]);
$stmt->execute();
