Я использую старый скрипт, который я использовал в предыдущих проектах для загрузки изображений. В проекте использовались только HTML и PHP, что облегчало загрузку ! :)
Я довольно новичок в обработчиках Jquery и Ajax, и из-за моих текущих проектов, использующих обработчики, мне нужно загружать вещи без обновления всей страницы, возможно, просто div.
Мой сценарий:
function postfile() {
var filename = $("#image").val();
$.ajax({
type: "POST",
url: "pages/minutes1.php",
secureuri:false,
fileElementId:'image',
enctype: 'multipart/form-data',
data: "submit=yes&image=" + {file: filename},
success: function(msg5){
$("#upform").html(msg5);
}
});
}
Мой PHP и HTML:
<?
/**
* The following uploader was not originally suited for text based files<br>
* Copied and Re-used from previous projects<br>
*/
$submit = $_POST['submit'];
if($submit=="yes")
{
//define a maxim size for the uploaded images in Kb
define ("MAX_SIZE","100");
//This function reads the extension of the file. It is used to determine if the file is an image by checking the extension.
function getExtension($str) {
$i = strrpos($str,".");
if (!$i) { return ""; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}
//This variable is used as a flag. The value is initialized with 0 (meaning no error found)
//and it will be changed to 1 if an error occurs.
//If the error occurs the file will not be uploaded.
$errors=0;
//checks if the form has been submitted
//reads the name of the file the user submitted for uploading
$image=$_FILES['image']['name'];
if(!$image){
?>
<table border="0" width="100%" cellspacing="0" cellpadding="0">
<tr>
<td class="tabcol1 font1" style="text-align: center;">
There was no minutes file attached!
</td></tr>
<tr>
<td class="tabcol4 font1" style="text-align: center;">
Please wait as you are directed back
</td></tr>
</table>
<?
}elseif($image)
{
//get the original name of the file from the clients machine
$filename = stripslashes($_FILES['image']['name']);
//get the extension of the file in a lower case format
$extension = getExtension($filename);
$extension = strtolower($extension);
//if it is not a known extension, we will suppose it is an error and will not upload the file,
//otherwise we will do more tests
if (($extension != "doc") && ($extension != "txt") && ($extension != "pdf") && ($extension != "odt") && ($extension != "docx") && ($extension != "rtf"))
{
?>
<b>The file type uploaded is not supported!</b><br><br>
<b>Supported formats:</b> doc, docx, pdf, odt, txt, rtf
<?
}
else
{
//get the size of the image in bytes
//$_FILES['image']['tmp_name'] is the temporary filename of the file
//in which the uploaded file was stored on the server
$size=filesize($_FILES['image']['tmp_name']);
//compare the size with the maxim size we defined and print error if bigger
if ($size > MAX_SIZE*1024)
{
?>
File size, too large! (if you need lieniency please contact webmaster)
<?
}else{
//we will give an unique name, for example the time in unix time format
$exam = substr("$filename", 0, -2);
function MakeRandom($minLength, $lastNr){
$i = 0;
while ($i <= $minLength){
$randomnr = ($i === $minLength) ? 1 : rand(0, 9);
$strNumber = (!$strNumber) ? $strNumber = $randomnr : $strNumber .= $randomnr;
$i++;
}
return $strNumber;
}
// show the number
$num = MakeRandom(5, 1);
$col = "$exam$num";
$image_name = $col.'.'.$extension;
//the new name will be containing the full path where will be stored (images folder)
$newname="minutes/".$image_name;
//we verify if the image has been uploaded, and print error instead
$copied = copy($_FILES['image']['tmp_name'], $newname);
if (!$copied){
?>
File uploaded and E-mail sent!
<?
}
}
}
}
}else{
?>
<div id="upform">
<form method="post">
<table border="0" width="100%" cellspacing="0" cellpadding="0">
<tr>
<td class="font1 tabcol1">
<!-- begin 2 column table -->
<table border="0" width="100%" cellspacing="0" cellpadding="0">
<tr>
<td class="font1">
<b>Choose a file to upload:<br> <input id="image" name="image" type="file" /><br />
<input type="button" id="submit" name="submit" value="submit" onclick="postfile()">
</td>
<td class="font1"></td>
</tr>
</table>
<!-- End 2 column table -->
</td></tr>
</table>
</form>
</div>
<?
}
?>
Проблема, которую я получаю, заключается в том, что даже после добавления файла и нажатия кнопки отправки, 1017 *
это дает мне ошибку без изображения.
Мне кажется, что я написал скрипт неправильно, но не смог найти никаких синтаксических ошибок.
Буду признателен за любую помощь!
Заранее спасибо:)
