href syntax : is it okay to have space in file name
提问by Moon
it has always been my practice that when ever i use images i name them like
walls_ico, bu_hover
我一直以来的习惯是，每当我使用图像时，我都会将它们命名为
walls_ico，bu_hover
so when i give paths they go like
所以当我给出路径时，它们会像
<img src="images/walls_ico.ico" />
<img src="buttons/bu_hover.png" />
UNTIL now when i am on a project where users upload files...
直到现在，当我在一个用户上传文件的项目中时......
i was wondering is it okay to have spaces between file and folders name like
我想知道文件和文件夹名称之间是否可以有空格，例如
<img src="buttons/bu hover.png" />

The srcattribute should contain a valid URL. Since space characters are not allowedin URLs, you have to encode them.
该src属性应包含有效的 URL。由于URL 中不允许使用空格字符，因此您必须对它们进行编码。
You can write:
你可以写：
<img src="buttons/bu%20hover.png" />
But not:
但不是：
<img src="buttons/bu+hover.png" />
Because, as DavidRR rightfully points out in his comment, encoding space characters as +is only valid in the query string portion of an URL, not in the path itself.
因为，正如 DavidRR 在他的评论中正确指出的那样，将空格字符编码+为仅在 URL 的查询字符串部分有效，而不是在路径本身中有效。

echo "<table border=2px style='border-radius=20px;' align=center><tr>
<th>Document ID</th>
<th>Document Name Type</th>
<th>Download Documents</th>
</tr>";//<th>Project Document Type</th>
while($row = mysqli_fetch_array($result)) {
$path1=$row['FOLDERNAME'] .'/'. $row['FILENAME'] .'.'. $row['DOCTYPE'];
$path=str_replace(" ", '%20', $path1);
echo "<tr>";
echo "<td>" . $row['DocID'] . "</td>";
// echo "<td>" . $row['PROJDOCTYPE'] . "</td>";Thank you. Your Apple ID is now ready for use.
echo "<td>" . $row['DOCNAME'] . "</td>";
echo '<td><a href=Tender/'.$path.'>'.$row['DOCNAME'].'</a></td>';
echo "</tr>";
}
echo "</table>";
mysqli_close($con);

spaces will be allowed only when you are working in local hosts
仅当您在本地主机上工作时才允许使用空格
