kate_rose Posted September 18, 2012 Share Posted September 18, 2012 Hi, I am working on a University server where they do not have Zend Framework installed and trying to get the ZendGdata client library working as a stand alone version. So I have been following the directions at https://developers.google.com/gdata/articles/php_client_lib I installed the ZendGdata in a folder in my websites root folder and started to run the php installation checker to make sure the library was accesible when I hit a roadblock. The installation checker does not work - it stops running midscript and spits out 1/2 the script on the screen instead of giving me the checker. Here is the script I copied from several different sites (none work) " <?php /** * Zend Framework * * LICENSE * * This source file is subject to the new BSD license that is bundled * with this package in the file LICENSE.txt. * It is also available through the world-wide-web at this URL: * http://framework.zend.com/license/new-bsd * If you did not receive a copy of the license and are unable to * obtain it through the world-wide-web, please send an email * to license@zend.com so we can send you a copy immediately. * * @category Zend * @package Zend_Gdata * @subpackage Demos * @copyright Copyright © 2005-2012 Zend Technologies USA Inc.

Christian F. Posted September 18, 2012 Share Posted September 18, 2012 Please use the tags around your code, as it helps make both your post and your code a lot easier to read.

Jessica Posted September 18, 2012 Share Posted September 18, 2012 So you want a bunch of strangers to validate your code rather than just either checking the config yourself or checking with your sysadmins? So my question is am I doing something wrong or does the university have the include ability turned off in their php.ini file (it kind of looked like that to me but I need to be sure of the code first).

kate_rose Posted September 19, 2012 Author Share Posted September 19, 2012 Thanks for the replies ChristianF & Jesirose. I am sorry I didn't put my code in the tags. It has been a very long time since I have been here my twin 3 yr. olds are finally in preschool & I have a part time job working on website design. I just included my code because I remember that when I don't someone asks me to. Anyway I will be sure to put the code tags in in the future. Jesirose I actually spent the last 2 days working on this and bugging my sysAdmin (they seem suprisingly uninformed). I have been through the code a couple times and I think it is correct (especially since the long bit was copied directly from the the website directions I am following). The only thing I am unsure of is the stuff I have to write myself since it has been so long here it is again $clientLibraryPath = '/www/ttunrm/ZendGdata/library'; set_include_path(get_include_path() . PATH_SEPARATOR . $clientLibraryPath); I read the php.ini file but the php I do know is all self taught so I was not sure. I have never written a php.ini file. these are the 2 excerpts which seemed relevant "When safe_mode is on, UID/GID checks are bypassed when ; including files from this directory and its subdirectories. ; (directory must also be in include_path or full path must ; be used when including) ; http://php.net/safe-mode-include-dir safe_mode_include_dir =" and " Whether to allow include/require to open URLs (like http:// or ftp://) as files. ; http://php.net/allow-url-include allow_url_include = Off" your help and your patience is much appreciated Thanks Kate Quote Link to comment https://forums.phpfreaks.com/topic/268523-getting-zendgdata-client-library-working/#findComment-1379163 Share on other sites More sharing options...
Jessica Posted September 19, 2012 Share Posted September 19, 2012 safe_mode_include_dir =" This seems like it should be a 0 or a 1. Also have you tried adding a trailing slash to $clientLibraryPath = '/www/ttunrm/ZendGdata/library'; to make it $clientLibraryPath = '/www/ttunrm/ZendGdata/library/'; Quote Link to comment https://forums.phpfreaks.com/topic/268523-getting-zendgdata-client-library-working/#findComment-1379173 Share on other sites More sharing options...
Christian F. Posted September 19, 2012 Share Posted September 19, 2012 safe_mode_include_dir is fine the way it is, unless safe_mode is actually set to 1. Then you might need to set a path on this, if you want to bypass the GUID/UID checks. So not necessarily required in then either. However, upon going through the code a bit, I did notice that there were some instances where errors have been suppressed by using @ in front of the function call. Remove these instances, turn on error reporting (if you haven't already), and go through the script step by step until you find exactly where it fails. Without this information and/or an error message, I'm afraid we really can't help you any further. At least not without replicating the exact environment in which you're experiencing the issue. PS: Make sure you put those two lines you were supposed to add, before you include the loader script. Or rather, before you make the InstallationChecker object. PPS: Also, I'm a bit confused as to why you're using the above class. Reason for this is that you noted that you don't have Zend Framework available, but the class in question relies upon Zend Framework and actually seems to exists solely to verify that the ZF installation is correct.

kate_rose Posted September 19, 2012 Author Share Posted September 19, 2012 Thanks, I did not have work today but I will be able to try out your suggestions tomorrow and will report back.

kate_rose Posted September 20, 2012 Author Share Posted September 20, 2012 OK, JesiRose I tried adding a slash with no results. I can't actually change the php.ini file as I understand it because the values are set for everyone using the server so I can't alter the values for things like "safe_mode_include". Of course the server folks emailed me to ask if I figured this out yet and apparently haven't checked to see if php_includes are turned off. Fortunately I am not sure the problem is on their end. Christian I turned on error reporting and ran my script again. It is reporting "no errors" but seems to be breaking (not sure if that is the right term) shortly after it gets started so what I get when I visit my installation_check website is a page full of most of the script code and at the bottom the report of no errors. It is breaking right after the first arrow before the second 'array' in the following bit of code private $_allErrors = array( self::PHP_EXTENSION_ERRORS => array( 'tested' => false, 'errors' => null), self::ZEND_GDATA_INSTALL_ERRORS => array( 'tested' => false, 'errors' => null), self::SSL_CAPABILITIES_ERRORS => array( 'tested' => false, 'errors' => null), self::YOUTUBE_API_CONNECTIVITY_ERRORS => array( 'tested' => false, 'errors' => null) ); what I see printed/typed out on the screen is the text of the code starting with the first array in the code scrap above I am still on a steep learning curve but all this bit is doing is setting up an array that contains 4 arrays with false or null values for the variables 'tested' &'errors' right? I couldn't find any other instance of the $_allerrors array in the code. I didn't write this I am just trying to use this code to figure out if my ZendGdata is correctly installed on the server so I am not sure what the $_allerrors array is for. Thanks again for your help.

kate_rose Posted September 20, 2012 Author Share Posted September 20, 2012 Is there some other script I can use to make sure the ZendGdata client library is available?

Christian F. Posted September 20, 2012 Share Posted September 20, 2012 What happens if you click on "view source" in your browser? Reason I ask is that it sounds like the PHP code is not parsed as PHP, which means that the file is either missing the correct extension (.php) or that there's some issue(s) on your server preventing PHP code from being parsed.

kate_rose Posted September 21, 2012 Author Share Posted September 21, 2012 Christian, I am pretty sure I looked at the code at one point with view source. It looked fine. I am also pretty sure that I created the file as a php file and it has the correct extension. I will double check at work in the morning. I know other php files seem to work OK on our server but this is the first one I have tried to create. If I need to I can bug my administrator again tommorow. Thanks for your help.
