Because it's a cursor and you're not resetting the position. You can't
print the entire result set this way - you have to iterate through the
result set in a loop, printing out the row on each iteration.

Re: [PHP] SQL Source Control
Richard Davey wrote: Hi all, I know a lot of you use various means for PHP source control (CVS, SVN, etc), which is all well and fine, but how do you manage source control on your databases? Say you've got an upgrade to a site, all of the new PHP files are controlled by SVN, so you can rollback at any time, but say the upgrade includes several key modifications to a MySQL table and perhaps the changing of some core data. How (if at all?!) do you handle the versioning of the database and data itself, so you can keep both PHP and SQL structure in sync? Cheers, Rich Rich, This is a well-known problem that comes from the fact that the database is an infrastructure component rather than a source component. You would have the same issue if you were to upgrade the operating system software, for example. What most people do is use their tool of choice to create the DDL/DML update scripts and put those under source control. To version the data you need to make database backups at well-understood times and grab the data files if appropriate. Rolling back a change is a matter of recovering the database and files to a point in time along with the sources. I don't know of any management tools for this part of it. Most larger organizations have different people responsible for the database and web tiers, so a single tool won't do. Some folks are trying to use ClearCase automation to manage a lot of it, but it's still a work in progress... In a smaller environment I would be inclined to create shell/whatever scripts to do the actual implementation. If you parameterize the connection/server details you can test the implementation in a QA environment before going live - less need for rollbacks that way. The shell scripts greatly reduce the chance of finger trouble which is key if your implementation is being done at some uncivilized hour or by rookies. If you want to truly embrace the New World, you can do all of this using Ant, which has built-in tasks for CVS/SVN as well as file movement, etc. It can also run shell scripts for the database stuff. ...Lori -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If your id should only have digits in it, use

This doesn't work with negative integers - it really checks to make sure

Re: [PHP] Need a working SOAP example using SOAP -- PHP is blocking the calls
Daevid Vincent wrote: c, could you be having a problem related to the allow_url_fopen ini setting? Now we're talkin! Okay, I made sure that allow_url_fopen and allow_url_include are both on. Verified via phpinfo(); Still no luck. :-\ However, this sparked an idea... I have been using my WinXP and IE to hit my Gentoo notebook running apache2/php/etc. (samba mounting the /home/machine/... to edit the files) When I fired up KDE and hit the EXACT same pages (which are now local), they magically worked! So now the question is, what setting do I have to change in my php.ini file to get remote requests to work? I'm not following what you mean by local and remote and when your considering something to be one or the other. (locutus) Gentoo/Notebook/Apache/PHP/Samba (gabriel) WinXP/IDE/IE6 All the code sits on locutus. I samba share the directory so can edit in my HomeSite IDE on gabriel. I edit my 'hosts' file (on both machines) to point at the proper IP (172.16.35.223 machine.locutus.com) setting up a vhost on locutus, etc... I can make the initial connection to client.php. I can do most anything (php, mysql, htaccess, etc), as locutus is a webserver -- I use this method to develop a dozen sites, all work flawlessley. You follow so far? This should be a pretty normal setup. Nothing fancy here. So, as stated in previous post. If I use gabriel to access http://machine.locutus.com, I can get to any of the individual pages related to this SOAP exercise (server.php, .wsdl, client.php, etc.). The problem is that the client.php can't make a server.php call though, and throws that exception. Now, to add to my confusion and simultaneiously lets me know that my actual CODE is working, as per the spark above, I fired up KDE on locutus. Then I hit the exact same URL, and pinch my ass and call me Charlie, the SOAP example works. SAME EXACT CODE. SAME EXACT FILES. SAME EXACT URLS. Something in PHP land (php.ini) seems to be horking me. I had a co-worker put my code on his linux (debian) box, and he could then connect from his XP to the URL and it worked for him too (even using https://). You might be thinking, well just diff the php.ini files and see. Not so easy my friend. They're not condusive to that. And we tried to eyeball what we could, but didn't see anything obvious. I thought for sure allow_url_fopen and allow_url_include were my silver bullets here, but they're 'On' in both php.ini files (his and mine). windows firewall springs to mind but I can't tell if it could even be involved from your current description. Windows Firewall should not be an issue here b/c the soap requests are originating from locutus to locutus -- the files are in the same directory. SOAP (at this stage) is only an exercise -- it's not making any remote calls across a network. Daevid, I am by no means an expert on this, but I know that when we've had issues with running some scripts, we had to look into the Linux security settings. We're running SE Linux (Red Hat) and that shuts down a lot of the remote access. When we were trying to get some CURL scripts working, we had to temporarily disable the Linux firewall so that we could track the calls in the messages log. Then we could see what the required privileges were and set things up appropriately. I don't know if Gentoo has anything like that or if you have any of the security stuff turned on, but you might want to check the equivalent of the messages log in Gentoo and see if that's where you're being blocked.

This can only be done with Javascript if you don't want to leave the

And so, you're on the wrong list, search for a javascript list :)
Tijnema
Actually, that's not quite true. It's usually easier in Javascript, but
if you want to do a pure PHP method, read on. This does require that
you use the POST method for your form, but that's usually preferred anyway.
?php if ($_SERVER['REQUEST_METHOD'] == 'GET') { ?
form action=?php echo $_SERVER['SCRIPT_NAME'] ? method=post
// Regular form contents go here
/form
?php } else {
// Insert form processing code here - including field validation
}
?
This uses the PHP SCRIPT_NAME server variable for the form name so that
you don't have to worry about the script location and you can move it if
necessary without having to change the script. I copied this from PHP
Cookbook by O'Reilly. It's not a bad book, if you can get it where you
are...

Re: [PHP] Question about form submitting / clarification
Mário Gamito wrote:
Hi,
Of the three items you specify a and b should be handled with Javascript
in an onsubmit handler. The error messages would be generated by this
handler. Email validity would have to be handled by the web server and
your php script, usually by trying the address.
I think i was misunderstood.
I know how to do the error handling.
What i don't know is how to display the error messages in the same page
as the submit form.
Warm Regards
To expand on my previous response: create a function that displays the
form and takes an errors array as an argument. The function would
display the form with print commands that would display the error
messages. If there are no errors, then just the form is displayed, but
if there are errors they are printed right next to the form element.
For example:
in display form function:
$defaults['name'] = isset($_POST['name']) ? htmlentities($_POST['name'])
: ' ';
tdYour Name:/td
td?php print_error('name', $errors) ?
input type='text' name='name' value='?php echo $defaults['name'] ?'
//td
You will also need a print error function that takes the input element
name and errors array as arguments. The $defaults variable is set to
blank if the form is being displayed for the first time or the value
input by the user if the form is being redisplayed after validation by
using the POST variables.
Lastly you will need a form validation function that would populate the
errors array. This would be an associative array with the form field
names as keys and the error messages as values.
The entire code is available in the book I mentioned previously. I
can't replicate it here due to the obvious copyright issues, although
the example code is available on O'Reilly's site
(http://www.oreilly.com/) Search for PHP Cookbook and select the second
edition.
This is all very difficult to explain in an email, but hopefully I've
given you enough to chew on, as it were...
