我目前有一个麻烦插入文件输入(图像)到我的数据库,但它返回我空值,当我试图将其插入数据库,其他文本输入已成功插入数据库,但图像除外。无法插入图像到数据库与ajax序列化函数
这里是我的Ajax代码,我用做AJAX功能:
$("#testing").confirm({
confirm: function (el) {
$.ajax({
url: 'bannerItem.php',
data: el.closest('form').serialize(),
type: 'post'
}).done(function() {
if(!alert('Banner Had Successfully Updated.')){document.getElementById('form').reset();}
}).fail(function() {
//if the post is failed show an error message if you want
alert('Some error occur. Please try again later.');
}).always(function() {
//this is executed on success and failure
$('#myhiddendiv').hide();
})
}
});
这里是PHP代码:
<?php
include 'dbConnection.php';
global $dbLink;
$target_file = basename($_FILES['uploaded_file']['name']);
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
//Check image file type
// Make sure the file was sent without errors
if($_FILES['uploaded_file']['error'] == 0) {
//Gather all required data
$item_id = $dbLink->real_escape_string($_POST['banner_id']);
$name = $dbLink->real_escape_string($_POST['bannerName']);
$data = $dbLink->real_escape_string(file_get_contents($_FILES['uploaded_file']['tmp_name']));
//Create the SQL query
$query = "INSERT INTO banner_item (banner_item_id, banner_name,banner_data,banner_created) VALUES ('{$item_id}','{$name}','{$data}', NOW()
)";
//Execute the query
$result = $dbLink->query($query);
//Check if it was successfull
if($result) {
echo 'Name : '.$name.'</br>';
echo 'Result : Success! Your file was successfully added!';
}
else{
echo 'Result : Error! Failed to insert the file'
. "<pre>{$dbLink->error}</pre>";
}
}
else {
echo'An error accured while thefile was being uploaded. '
. 'Error code: '. intval($_FILES['uploaded_file']['error']);
}
// Close the mysql connection
$dbLink->close();
// Echo a link back to the main page
echo '<p>Click <a href="index.html">here</a> to go back</p>';
?>
如果我使用的PHP代码withouth的Ajax的功能,一切可以插入到数据库中,但是当我使用ajax函数时,只有图像无法插入到数据库中。
这里是我用来提交价值形态:
<form id="form" action="bannerItem.php" method="POST" enctype="multipart/form-data">
<div class="box-body">
<input type="hidden" name="banner_id" value="1"></input>
<div class="form-group" >
<label for="bannerName">Banner Name 旗帜名称</label>
<input type="text" class="form-control" name="bannerName" id="bannerName" placeholder="Please Enter Name" onChange="checkDisabled(testing);">
</div>
<div class="form-group">
<label for="exampleInputFile">File input</label>
<input type="file" id="uploaded_file" name="uploaded_file" onChange="checkDisabled(testing);"><br>
<p class="help-block">Your picture size not more than 2MB. (Only JPEG/JPG/PNG is allowed)</p>
</div>
<div class="checkbox">
<button id="testing" type="submit" class="btn btn-primary" disabled>Update</button>
</div>
</div><!-- /.box-body -->
</form> <!-- D
我一直在寻找周围小时如何在计算器解决这个和谷歌,大多使用XHR2或FORMDATA但我我不确定使用哪一个以及如何将它用于我的代码,因为我仍然是一个使用AJAX和PHP函数的新人。如果我在我的Ajax代码上犯了任何错误,请引导我。谢谢你,祝你有美好的一天:)
您好,感谢给建议使用XHR2,但我仍然有一个文本文件要与图像一起插入,我该如何做到这一点?谢谢 – 2015-02-23 07:46:48
只需使用FileAPI插件即可。我认为你可以指定可用的扩展名来上传。 https://github.com/mailru/FileAPI 顺便说一句,如果你使用AngularJS我可以帮你一个指令。 – Kosmog 2015-02-23 07:57:00
