下面我有一个处理文件输入的 iframe:
var $fileVideo = $("<form action='videoupload.php' method='post' enctype='multipart/form-data' target='upload_target_video' onsubmit='return videoClickHandler(this);' class='videouploadform' >" +
"Video File: <input name='fileVideo' type='file' class='fileVideo' /></label>" +
"<input type='submit' name='submitVideoBtn' class='sbtnvideo' value='Upload' /></label>" +
"<p class='listVideo' align='left'></p>" +
"<iframe class='upload_target_video' name='upload_target_video' src='/' style='width:0px;height:0px;border:0px;solid;#fff;'></iframe></form>");
现在我在下面有一个函数,当文件停止上传并成功上传到服务器时,它将显示上传文件的名称:
function stopVideoUpload(success, videofilename){
var result = '';
videocounter++;
if (success == 1){
result = '<span class="videomsg'+videocounter+'">The file was uploaded successfully</span>';
$('.listVideo').eq(window.lastUploadVideoIndex).append('<div>' + htmlEncode(videofilename) +
'<input type="text" name="videoidhide" value=""/><br/><hr/></div>');
}
return true;
}
您还将看到文件名旁边有一个文本输入。这与我的问题有关。
下面是框架链接到的 php 脚本videoupload.php
,该脚本将上传文件并将数据插入数据库:
move_uploaded_file($_FILES["fileVideo"]["tmp_name"],
"VideoFiles/" . $_FILES["fileVideo"]["name"]);
$result = 1;
$videosql = "INSERT INTO Video (VideoFile)
VALUES (?)";
if (!$insert = $mysqli->prepare($videosql)) {
// Handle errors with prepare operation here
}
//Dont pass data directly to bind_param store it in a variable
$insert->bind_param("s",$vid);
//Assign the variable
$vid = 'VideoFiles/'.$_FILES['fileVideo']['name'];
$insert->execute();
if ($insert->errno) {
// Handle query error here
}
$insert->close();
?>
<script language="javascript" type="text/javascript">
window.top.stopVideoUpload(<?php echo $result; ?>, '<?php echo $_FILES['fileVideo']['name'] ?>');
</script>
下面是显示文件插入的示例数据库:
Video_Question 表:
VideoId (PK auto) VideoFile
1 VideoFiles/carrace.mp4
2 VideoFiles/cricket.mov
现在我的问题是,您在 mysqli 代码中看到它将上传的视频文件插入VideoFile
数据库中的字段的位置,我如何从VideoId
字段中检索值并将其显示在每个相关上传文件的文本输入中?
例如,如果 carrace.mp4 已上传,VideoId
则从数据库中检索 1 并将其显示在已上传文件名称旁边的文本输入中。
