Opera hangs when submitted POST form
Great in IE and Firefox

After clicking on submit, opera just hangs - no speed and time can go up to 4 min (like if it was parsing a file).
When typing the directly the url of the resutl page in Opera, it works fine.

It works great in IE and Firefox and I get the result page within a second.

Anyone knows why Opera do no respond to my simple form.
Opera 7.54 Win32 Windows XP

Thanks

If it's you own form, I suggest you split it into two, and move elements from one to the other until you identify the element that's causing the problem.

I found the problem but I can't resolve it yet.
It is because my form had some input=file and it hangs in the resultpage (at the parsing stage) because Opera blank input have as a default value 'none'
Read : [webmasterworld.com...]

It not only hangs when the input file is blank but also when I type text in the input field which are non relevant (such as "derefere" or "deerel").

What should I do to check that the data entered in the input file are correct (such as "D:\images\try.jpg") and be sure that OPera doesn't hang when data are incorrect.

Thanks

Please, I am stuck with Opera...

When leaving the field blank or typing wrong path or unrelevant text in the input file, Opera just hangs.

I have even put a exit(); statement on the first line of my result page (to force it to stop parsing) but it keeps hanging.

Furthermore, it even hangs when sending a .txt or .ini documents?

Spend the all day on Google doing search but found no solution.

Thank you

Sounds like a behavioural anomaly in Opera coupled with a server-side script failure.

Since I have no knowledge of php (just perl) I can't help further with this problem.

Good luck,

Kaled.

How about showing us the the relevant part of the processing script. Someone may be able to nail it down then.

Thanks a thousant for your help.
I have trim to show only the relevant part. I presume the error is in the form.

Just copy and paste and run it with Opera 7.54

If you leave the field blank, send a text file, ini file or type directly in the bar a wrong path or urelevant text, it should then hangs.

One thing I noticed is the lack of a MAX_FILE_SIZE field, which php.net says needs to be present and precede the file input.

if ($preview=="none") {echo "<p>Send your file</p>";
echo "<form method='post' action='load_try.php' enctype='multipart/form-data'>";
echo '<input type="hidden" name="MAX_FILE_SIZE" value="30000" />';
echo "<input type='file' name='imagefile' class='form1'>";
echo "<input name='preview' type='hidden' value='sendpic'>";
echo "&nbsp;&nbsp;&nbsp;<input type='submit' name='prev' value='PREVIEW' class='form1'></form>";
echo "</p>"; }

Try that and see what you get.

Thanks Birdman,
Indeed, I forgot this one but it does not help.

Sorry, I forgot to mention for those who are ready to try the script that it should saved as 'load_try.php'.

Not sure if it's goint to help, but the last block of code isn't right.

else {
$preview = "confpic";
//************
//COPY PICTURE
//************
echo "<br>OK PICTURE WILL BE COPIED AND THUMBNAIL GENERATED<br>"; }

echo "</p>";

//+++++++++++++++++++++++
//***********************
//RESUBMIT BECAUSE ERRORS
//***********************
//+++++++++++++++++++++++
if ($preview == "error") {
echo "<p>RE-Send your file</p>";
echo "<form method='post' action='load_try.php' enctype='multipart/form-data'>";
echo "<input type='file' name='imagefile' class='form1'>";
echo "<input name='preview' type='hidden' value='sendpic'>";
echo "&nbsp;&nbsp;&nbsp;<input type='submit' name='prev' value='PREVIEW' class='form1'></form>";
echo "</p>";
}

if($preview == "confpic") {
echo $brk;
echo "<br>OK PICTURE WILL BE COPIED AND THUMBNAIL GENERATED<br>";
} }

That last two if($preview == ...) bits need to be outside of the the last else block. see, $preview will always == error in that block because you set it just after the else. I know that didn't make much sense :) Just try moving the last two if blocks outside of the last else.

else {
$preview = "confpic";
//************
//COPY PICTURE
//************
echo "<br>OK PICTURE WILL BE COPIED AND THUMBNAIL GENERATED<br>"; }

echo "</p>";

}

echo "<input name='preview' type='hidden' value='sendpic'>";

}

Thanks for your remakr Birdman, sadly it will not resolve the problem I have with Opera.
BTW, did you try the script in Opera?

Nonetheless, I take note of your last remark.

I just tried it and it loads okay. There is another error though:

$widthp = $sizeb[0];
$height = $sizeb;

should be:

$widthp = $sizeb[0];
$height = $sizeb[1];

You have tried and it load fine.
Which version of Opera do you have?
Did you tried to submit it with no value or with a .txt file?

This is strange!

Thanks for all your effort, btw
Hear from you tomorrow, going home now.

I don't know if it's of any help, but there is a known problem when submitting forms in Opera. This often happens when posting a comment on sites like A List Apart - it can hang for ages. It's not Opera's fault though, but the server's. It should be sending back a specific code, but a lot of servers don't send the correct code. Of course browsers like IE ignore the code, but Opera is much stricter. If all servers were configured properly, then this wouldn't happen. (Though I do wish Opera would allow for this situation as it makes itself look bad.)

I cannot confirm this is definitely the case, but I read about it once for sure.

:LOL )
Thanks Hester.
This is the answer you just gave me at opera's forum.
Not much reply for the moment at opera's forum.

I have answered you

>> I don't know if it's of any help, but there is a known problem when submitting forms in Opera.

I am aware that they are known problem in form, especially with enctype='multipart/form-data due to security flaw. I know for example that when left blank, the value by default in Opera is 'none'

>> This often happens when posting a comment on sites like A List Apart - it can hang for ages. It's not Opera's fault though, but the server's.

I do not think that Opera hang due my server's fault. I presume it is really Opera which do not respond.

>> It should be sending back a specific code, but a lot of servers don't send the correct code.

Which code are talking about?
