Uploading a file to a website from camera or photo library hangs

[pmehrotr]

I have a web site/app (my own) on a server which I access from Safari on ipad. This web site has a web form. I used to upload file (such as a picture taken from camera or select a file from photo library) without any problems until I upgraded to ios 11.4.1. Now file upload just hangs and eventually times out. I searched on google and is not clear what is needed to fix the problem.

My web form uses <input type="file" ....>
Then I have Upload button and I click on it, then java script uses jquery's ajax call to a Rest Web Service on my webapp to upload file. html code fragment is shown below:

<thead>
<tr>
<th class="col-xs-4">File to Uplaod</th>
<th class="col-xs-4">Save As</th>
</tr>
</thead>
<tbody>
<TR>
<TD> <input class="filename file" name="files[0]" type="file"></TD>
<TD> <input id="frname[0]" type="text" class="newfilename form-control input-md" placeholder="Enter a file name with extension" ></TD>
</TR>
<TR>
<TD> <input class="filename file" name="files[1]" type="file"></TD>
<TD> <input id="frname[1]" type="text" class="newfilename form-control input-md" placeholder="Enter a file name with extension"></TD>
</TR>
<tbody>
</TABLE>
</div>
<br>
<input type="button" class="btn btn-info" onclick="AddMoreFile('attachTable')" value="Add More Files" />
<div class="h-divider"> </div>
<section id="uploadattach">
<h3>&nbsp;</h3> <!-- used to creare some space -->
<div class="form-group">
<div class="col-xs-offset-4 col-xs-8" class="row">
<button id="uploadattachbut" type="submit" onclick="doUploadButtonAjaxPost()" class="btn btn-primary">&nbsp;&nbsp;Upload&nbsp;&nbsp;</button>
</div>
</div>
</section>
</form>


How can I fix the problem so file will be loaded. Can some security seeting changed in Safari or ios somewhere to fix the issue.

Appreciate any help.

This link helped me. Problem was that my web form which uploads files has a row which was blank, i.e., no filename was specified.

It seems that this bug was introuced in ios aftre 11.1, that's why 11.1 works but 11.4.1 does not. Hope this answer will be helpful to others.
