[fw-general] Error Handling w/ Zend DB
I'm trying to handle errors appropriately after an insert into MySQL with Zend_DB and the MySQLi plugin, but I'm having a rough time determining the cause of the error. For example, I'd like my application to catch the exception, determine if the exception occurred due to a unique key violation, and then if so, identify the column that is causing the violation. I noticed that the type of the exception returned is Zend_Db_Statement_Mysqli_Exception, and here's all of the information I could get out of it - getCode(): 0 getFile(): D:\Apache224\htdocs\CK\library\Zend\Db\Statement\Mysqli.php getLine(): 237 getMessage(): Mysqli statement execute error : Duplicate entry '1' for key 1 Does this mean that I need to parse the message to determine exactly what caused the exception, or is there some other way for me to perform error handling w/ Zend DB? Thanks, - Ryan
[fw-general] quoteInto vs bound parameters
I've been looking through the Zend_Db documentation, and I'm wondering why you would ever want to use quoteInto() or quote() as opposed to binding your parameters in an array. What's the advantage to quoteInto()/quote()? Isn't the separation of data provided by bound parameters always going to be more secure than attempting to manipulate the strings? As I understand it, all statements are prepared anyhow, so why not use more bound parameters? For example, wouldn't bound parameters always avoid bizarre problems like unicode SQL injections [http://bugs.mysql.com/bug.php?id=22243], whereas with quote/quoteInto you're trusting the string parse to get it right? I'm curious because it looks like relatively few methods (none?) in Zend_Db_Table support bound parameters. To use binding, I need to go to the adapter every time, which makes my Zend_Db_Table class somewhat less convenient. I'm new to ZF, so maybe I'm just missing something really obvious here. I'd appreciate it if anyone could provide some insight. Thanks, - Ryan
[fw-general] ZF changing the cwd
Sorry for both posts in such a short period of time, but I even though I've worked around this in my own environment, I thought this post might save someone else some debug effort. I'm setting include_path with relative paths in php.ini (and appending to it in my bootstrap script) and I'm using numerous Zend_* classes all throughout my code without any trouble, but at one point in my application I hit an error that indicates Zend_Filter is unable to find Zend_Loader. This doesn't make sense because I use Zend_Loader all over the place, including in my bootstrap script. After further investigation, it looks like something is altering my working directory. I put in an echo getcwd(); at the beginning of my app, and another right before I access Zend_Filter (for the 2nd or 3rd time...), and getcwd() clearly demonstrates that the working directory has changed - IINITIAL CWD: D:\Apache224\htdocs\main Session open... Reading session... GC-ing sessions... Writing session... PRE-FILTER CWD: D:\Apache224 *Warning*: Zend_Filter::require_once(Zend/Loader.php) [ function.Zend-Filter-require-oncehttp://localhost/CK/function.Zend-Filter-require-once]: failed to open stream: No such file or directory in * D:\Apache224\htdocs\CK\library\Zend\Filter.php* on line *88* *Fatal error*: Zend_Filter::require_once() [function.requirehttp://localhost/CK/function.require]: Failed opening required 'Zend/Loader.php' (include_path='.;./application/controllers;./application/models;./application/config;./application/util;./library') Some random Googling brought me to this page - http://www.php.net/ob_start Some web servers (e.g. Apache) change the working directory of a script when calling the callback function. You can change it back by e.g. chdir(dirname($_SERVER['SCRIPT_FILENAME'])) in the callback function. I'm using Apache, so I did a quick search through the ZF code and I found 12 different occurrences of ob_start. To narrow it down, I threw echo statements before each one, and the only one being called is the one in Zend\Controller\Dispatcher\Standard.php on line 233. Could this be a potential defect? Known issue? Right now, I'm using absolute paths in my include_path to work around it. Thanks, - Ryan
Re: [fw-general] Error handling with mysqli adapter
Thanks Eric - this was right on the money. I found my answer here - http://www.mail-archive.com/[EMAIL PROTECTED]/msg28759.html I have a custom session handler that's actually doing the write, and it looks like PHP is running it after the script is finished executing. If I move the same code into a normal block, I see a sane error message.

I can't remember what the exact error message actually means (Positive it was discussed though).
[fw-general] Using the Redirector helper outside of an Action Controller
I'm trying to implement a little routing in my bootstrap script (before the
dispatcher starts). Essentially, under very specific conditions, I need to
alter the controller that is invoked. I found
Zend_Controller_Action_HelperBroker and the Redirector, but I can't seem to
get them to function outside of an Action Controller. I've tried various
combinations of code similar to this -
$redirector =
Zend_Controller_Action_HelperBroker::getExistingHelper('Redirector');
$redirector-goto('index');
...but nothing seems to work. I've looked through the docs, and all of the
examples seem to function inside of a controller. Is there an easy way to
accomplish what I'm trying to do?
Thanks,
- Ryan
