[英]photo not storing onto the database. php [undefined Index]
我有这样的形式:
<form class="wrefresh" action="Code Files/Accused.php" method="post" enctype="multipart/form-data">
<div class="row-form">
<div class="span3" style="margin-top: 06px">Picture:</div>
<div id="photo_settings2" style="margin-left:11px;">
<img id="Picture2" src="../../img/User No-Frame.png"/>
</div>
<div id='Upload_Panel'>
<input name="file" type='file' id='file_browse' onchange="readURL(this,'Picture2')" style="cursor: pointer;"/>
</div>
</div>
<button type="submit" class="a-btn2"style="cursor: pointer; background-color:#5C635F; color:white; font-family:'Candara'; margin-top:-47px; margin-left:192px; height:37px;"><big>Submit</big></button>
</form>
我在Accused.php中有一个php代码:
$Mother_Language = $_POST['mlang'];
$Other_Languages = $_POST['olang'];
$Complexion = $_POST['comp'];
$Previous_Thug_Record = $_POST['precord'];
$Religion = $_POST['religion'];
$Type_of_Accused = $_POST['taccused'];
$City = $_POST['city'];
$Country = $_POST['country'];
$Nationality = $_POST['nationality'];
$ID_Mark = $_POST['idmark'];
$Hair_Color = $_POST['haircolor'];
$Occupation = $_POST['occupation'];
$Academic_Info = $_POST['ainfo'];
$Alias = $_POST['alias'];
$Caste = $_POST['caste'];
$Sect = $_POST['sect'];
$Remarks = $_POST['remarks'];
$photo = $_POST['file']; // giving error : undefined index/ getting nothing from the form.
<script>
var frm = $('.wrefresh');
frm.submit(function (ev)
{
ev.preventDefault();
var postdate = $(this).serialize();
var path = $(this).attr("action");
var mehtodtype = $(this).attr("method").toUpperCase();
$(".loadingimg").show();
$.ajax
({
type: mehtodtype,
url: path,
data: postdate,
success: function(data)
{
// Get Form Data.
$("#FIRtable").html(data);
$("#Accusedtable").html(data);
// Clear fields data.
$('form :input[type=text], textarea').attr('value', '');
// show hide icons when click on submit.
$(".loadingimg").delay(1000).fadeOut();
setTimeout(function()
{
$(".okicon").fadeIn('slow');
$(".okicon").delay(2800).fadeOut();
}, 1800);
}
});
});
</script>
我认为我的错误是由于我使用的Ajax函数。 除了$photo = $_POST['file'];
之外,我正在使所有工作正常$photo = $_POST['file'];
这//给出错误: undefined index
。 帮助将不胜感激。
通过AJAX上载文件比仅引用$_FILES
数组要复杂得多。 您将需要以下内容来处理文件上传:
function upload_file() {
var formData = new FormData( document.getElementById( "form-uploader" ));
$.ajax( {
url : "Code Files/Accused.php",
type : "post",
xhr : function() {
my_xhr = $.ajaxSettings.xhr();
if( my_xhr.upload ) {
my_xhr.upload.addEventListener( "progress", handler_progress, false );
}
return my_xhr;
},
beforeSend : handler_before_send,
success : handler_complete,
error : handler_error,
data : formData,
contentType : false,
processData : false
} );
}
此代码与您的代码之间的主要区别在于,它使用了JavaScript FormData
对象,这是使用AJAX上传文件所必需的。
然后,将在上载开始,其进度如何,是否有任何错误以及何时完成时调用各种支持功能:
function handler_progress( e ) {
if( e.lengthComputable ) {
$( "progress" ).attr( {value:e.loaded, max:e.total} );
}
}
function handler_before_send( e ) {
var progress = $( "<progress></progress>" ).attr( "id", "progress-bar" );
$( "#form-uploader" ).append( progress );
}
function handler_error( e ) {
alert( "error" + e );
}
function handler_complete( e ) {
// The browser has completed the upload, do any clean-up here
}
这主要是复制和粘贴我所做的项目(其中有一些更改以将其与您的代码绑定),我在其中一个项目中进行复制,因此您将看到ID中引用的一些元素您必须修改的HTML。 但这实际上是您要通过AJAX上传文件的目的。
