[英]Issue with uploading multiple files on a single html page using php
I am trying to build a web page where users can edit images portrayed on their public pages. 我正在尝试建立一个网页,用户可以在该网页上编辑其公共页面上描绘的图像。 There are 3 images that display on their public page and I've set up 3 HTML forms in order to handle the 3 separate files.
公共页面上显示3张图片,并且我已经设置3个HTML表单来处理3个单独的文件。
I only have 1 listed below because once I figure out the fix to 1 I'll be able to duplicate the fix to the other 2, 我下面只列出了1个,因为一旦找出了对1的修复,我就可以将修复复制到其他2个,
I have other upload pages on my website and they work fine, but for some reason this page is giving me trouble. 我的网站上还有其他上传页面,它们可以正常工作,但是由于某种原因,该页面给我带来了麻烦。 I can select a file but when I want to upload it my php code doesn't read that there is anything being posted.
我可以选择一个文件,但是当我要上传它时,我的PHP代码没有读取任何内容。
*I've commented out the function call (I know it works) I just need to know why my php code won't read that there is a file there. *我已经注释掉了函数调用(我知道它可以正常工作),我只需要知道为什么我的php代码不会读到那里有文件。
If I had to guess it'd be something with how it's named or how it's being tossed to the php code. 如果我不得不猜测这与它的命名方式或如何扔到php代码有关。
The code looks like this: 代码如下:
<div class="academic" style="width:250px;">
<br>
<?php
if(isset($_FILES['aca']) === true)
{
echo 'please print'; //It doesn't
if(empty($_FILES['aca']['name']) === true)
{
echo 'Please choose a file! <br>';
}
else
{
$allowed = array('jpg', 'jpeg', 'gif', 'png');
$file_name = $_FILES['aca']['name'];
$file_extn = strtolower(end(explode('.', $file_name)));
$file_temp = $_FILES['aca']['tmp_name'];
echo '<br>';
echo '<br>';
print_r($_FILES['aca']['tmp_name']);
echo '<br>';
echo '<br>';
if(in_array($file_extn, $allowed) === true) {
//upload_image($file_temp,$file_extn);
echo 'You have uploaded a picture!';
echo '<b><h3>Press submit again to finish the upload</h3></b>';
//echo "<script>window.top.location='../hidden/viewPNM.php?id=$permi'</script>";
}
else
{
echo 'Incorrect File Type!! <br> Allowed: ';
echo implode(', ', $allowed);
}
}
}
?>
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="aca" id="aca">
<input type="submit" value="Upload">
</form>
</div>
</span>
Okay...here is what you can try to do: 好的...您可以尝试执行以下操作:
Move the whole PHP code UNDER the form code.
将整个PHP代码移到表单代码下。 I remember that sometimes wierd bugs with that were happening, and the code didnt run
我记得有时会发生一些奇怪的错误,并且代码没有运行
If that doesnt work, do following: 如果那不起作用,请执行以下操作:
Change
<input type="file" name="aca" id="aca">
to<input multiple="true" type="file" name="aca[]" />
将
<input type="file" name="aca" id="aca">
更改为<input multiple="true" type="file" name="aca[]" />
Add this code above the submit button:
<input type="hidden" name="sendfiles" value="Send Files" />
将此代码添加到“提交”按钮上方:
<input type="hidden" name="sendfiles" value="Send Files" />
Replace
if(isset($_FILES['aca']) === true)
withif(isset($_POST['sendfiles']))
将
if(isset($_FILES['aca']) === true)
替换为if(isset($_POST['sendfiles']))
If this doesn't work, I can offer you a way to allow multiple files being uploaded from one button. 如果这不起作用,我可以为您提供一种方法,允许从一个按钮上载多个文件。 (Took the code from my website I made before)
(从我之前制作的网站上获取代码)
