Rant on my favourite topics : LC server with a side-dish of on-rev :-)

[Matthias Rebbe]

Alex,

you are not alone. I  noticed something similar with LcServer 7.10 on the On-Rev server Tio.
$_post arrays where empty when data was formatted with libUrlMultipartFormData,
while $_post_raw showed the content. So it was not possible to post larger binary data to LcServer.

I send a support request already in April this year informing the On-Rev team that the installed LcServer version is not able to handle http posts when the data was formatted with libUrlMultipartFormData.
I decided to install my own version of LcServer (in my case LC9-dp6 at that time) using the .htaccess method, which solved my problem immediately.

The only caveat: If you have several add-on domains and each domain uses its own root folder under public_html, e.g.
public_html/domain1
public_html/domain2
or whatever the folder names are, you have to install your custom LcServer for each domain separately into the cgi-bin folder of each of that root folders
public_html/domain1/cgi-bin
public_html/domain2/cgi-bin

If all of your domains use public_html as the  root folder then just install it into

public_html/cgi-bin


My .htaccess looks like this, in case you are interested. This version work also with HostM accounts, while the htaccess example in the LcServer lesson doesn´t.

#
RewriteEngine on
# this suPHP…  btw allows to set php settings using a php.ini file which is stored in public_html folder
# it is not needed on HostM accounts, because PHP settings can set in cPanel there.
suPHP_ConfigPath /home/YOURACCOUNTNAME/public_html/
<Files php.ini> 
order allow,deny 
deny from all 
</Files>

Options +ExecCGI
# path the the LcServer executable
Action custom-livecode /cgi-bin/livecode-server-9dp6/livecode-server
<FilesMatch ".+\.lc$">
SetHandler custom-livecode
</FilesMatch>
# 

The permissions of the folders and the LcServer executable are set to 755. The driver and external files  are set to 644.


Maybe this will “calm" you down a little bit. ;)
Have a nice weekend.

Just forgot: Would you please be so kind and share the information which library does contain the  ArrayToJSON() function? Did you already try it out using it on LcServer?

Regards,

Matthias

However, for the site owner to upload photos, I needed to revive my script for uploading files (specifically images), which hasn't been used in a while. And indeed, may have been played around with in the meantime - so I can't be sure that this is exactly a "once-working" script.

> which uses the (newer) $_FILES array which does the complex parsing of the file info from the form - a big improvement !! And indeed, the example there works does work. BUT - it seems that although it correctly parses out the file information, it loses any other POSTed values. So if your form consists *ONLY* of one or more files to upload - you're good. But if you pass any other values (e.g. folder you want it to go to, meta-info, passwords, etc.) that is all lost. Which basically means it's unusable for any real scenario.
