Step 3 of installation is blank

[shane]

After entering the database information (which I'm positive is correct) and pressing "next" the page is totally blank (oc-installer/index.php?step=3), if I view the page source there is nothing there. If I access the page directly (oc-installer/index.php?step=3) it shows. It's only when I post to it from oc-installer/index.php?step=2.

Requirements are all met according to the first step of the installation:
 

Code: [Select]

All right! All the requirements have met:

PHP version >= 5.x
MySQL extension for PHP installed
GD extension for PHP installed
Folder "oc-content/uploads" exists
Folder "oc-content/uploads" is writable
Root direcotry is writable
No idea why, nothing in the Apache error logs. Running Apache 2.2.16 with PHP 5.3.3.

Any ideas?

Could it be that you are working with version 1.0 ?

This error was removed in version 1.01

As ljhelbo says, which version are you using?

Today we're rolling out another version, stay tuned to blog: http://osclass.org/blog Try this one and tell us if it works well to you.

Sorry, I forgot to mention that. I've tried 1.0.1 and I've tried the latest version from svn (3 days ago).

After quite a bit of poking around I've found the issue. There were absolutely no errors about this anywhere so it took a bit of time to work it out.

OSClass actually uses the MySQLi PHP extension. This was not installed on my server. I have since installed it and OSClass has installed successfully.

It would be good for something to check this on the first step of the installation, perhaps a change as simple as this:

http://code.google.com/p/osclass/source/browse/trunk/webapp/oc-installer/index.php?r=727#300

   $checks = array(
            'PHP version >= 5.x' => version_compare(PHP_VERSION, '5.0.0', '>='),
            'MySQL extension for PHP installed' => extension_loaded('mysql'),
            'MySQLi extension for PHP installed' => extension_loaded('mysqli'),
            'GD extension for PHP installed' => extension_loaded('gd'),
            'Folder "oc-content/uploads" exists' => file_exists('../oc-content/uploads'),
            'Folder "oc-content/uploads" is writable' => is_writable('../oc-content/uploads'),
    );

http://code.google.com/p/osclass/source/browse/trunk/webapp/oc-includes/osclass/db.php?r=727#89

/**
 * Check PHP requirements needed to run the functions on this file.
 */
function osc_dbCheckRequirements() {
        if(!extension_loaded('mysql')) {
                throw new DBException(__('The required mysql extension is not loaded'), 0);
        if(!extension_loaded('mysqli')) {
                throw new DBException(__('The required mysqli extension is not loaded'), 0);
        }

wow, great work! I didn't notice it. It's changed in the svn trunk: http://code.google.com/p/osclass/source/detail?r=728

Thanks a lot!

No problem. Glad I could help .
