Pretty simple question, how do you send data from one form to another via a hyperlink?

I'm not able to test this at the moment, but are you able to just do:
<a href="update_user.php?<? $POST_['userID'] ?>">Update User</a>

Basically, on users.php it lists all the users in the database, and there is a form at the bottom to add a new user to the database. The aforementioned list is printed out so they're clickable links to the update_user.php form.

But then on update_user.php, I don't know how to actually pull out their userID from the previous page to run my select statement from the database.

God I hate PHP so much.

Something like this:

code:

<a href="update_user.php?userid=<? $_POST['userID'] ?>">Update User</a>

Then on the update_user page, you can pull that userid with:

code:

$_GET['userid'];

Security issues aside, that is the most simple approach.

Not to white-knight PHP, but I very much doubt any other web language would handle this differently. How else do you expect to have a link send information to another page? You have to rely on something being in either a GET variable or a POST variable in this situation. How PHP handles those is not, I believe, any worse than any other language. It seems pretty basic. (Now, if we get into $_REQUEST then it gets dicier, but no one should be doing that anyway, imo)

This seems akin to saying, "Pretty simple question, but how do I accelerate? God I hate Fords so much."

Fair enough- I guess I should've just said, "god I hate web development", as I'm much more comfortable working with a console / windows forms.
I wasn't trying to bash the language or anything. I do like web development and I think there's a lot more power in it than working with window forms as I said, but for now it just doesn't make sense to me.

Ah, okay then. Yeah, it can seem very convoluted to do the simple act of communicating between pages. It can be a really big leap to grok how the interaction between forms and data works, not to mention the fact that every request is almost completely atomic, independent of all previous and future requests, meaning you have to communicate the state of the program with each request, either through a form variable or in a session. I remember when I was first starting, I would always type up the form, then immediately below it type up the code to process the form, and then stare in confusion while I tried to figure out just what order this was all supposed to go in.

Comprehending the general flow of the program is probably the biggest early hurdle.

sonic bed head: Dec 18, 2003; this is naturual, baby!

I am a long time Java guy who just started at a company with a fairly recently built legacy PHP application. It's half in Zend + PHP5 OO and half in horribly procedural + millions of globals type code.

I am trying to figure out how I can create a separate package of PHP code that I can reuse in multiple contexts. For example, in Java, I can create a whole new java project, then package it as a jar and then include that jar wherever I want.

The problem I'm having is how I can do this and still maintain two different autoloading functions because I need this to work within and outside the Zend framework context.

I looked at this blog post - http://jacwright.com/40/php-package-management-and-autoloading/ and it seems to give a fairly straightforward solution, but I don't know if that is the standard way of doing things.

Thank you for your help!

If you're on PHP 5.3, you might want to look at using namespaces and a PSR-0 autoloader. If you also really, really want to bundle your PHP files together, take a look at the PHAR extension, included by default in 5.3.

I'm finally taking the leap into moving from mysql into either PDO or mysqli. I have experience with mysqli, so I'd prefer that, but first I wanted to ask about my biggest annoyance with it:

Is there any way (including 3rd party libraries) to get an associative array out of a bound query result?

I hate having to do $o->bind_result($foo, $bar, $fnord, ...). It's so uncivilized.

A classic red herring. mysqli_result::fetch_assoc(), as you can see, is a function on the mysqli_result class. Unfortunately, when using a prepared statement, you are dealing with mysqli_stmt, which has no such function.

All it has is mysqli_stmt::fetch(), which as stated above will only put data into variables.

I actually don't care about bundling them together at all. I much more want them to be able to be used independently from the Zend framework as well as within it. I want it to be just like a java package that I can use. The problem I'm finding with this is that I'll have to somehow hook into the Zend autoloader in order to accomplish that. I think that I need to stop wishing that there was the java package mechanism in PHP. I don't like having to worry about all of these paths on the filesystem everywhere.

Yep, it looks like Magic quotes is on. I'll just use stripslashes since I might be changing hosts again in a few months.

Another question: Any reason why PHP isn't displaying my errors? Display_errors is set to 'on' and error_reporting is set to '6143' for the local value (the value of E_ALL). This is making my debugging a lot harder. A blank white page is displayed when I missed a semicolon.

One thing that the MySQL PDO driver does not currently support is SSL. It has been added to the PHP 5.3 branch so it's only a matter of time until the next official release. This only matters if you don't run on dedicated hardware or are connecting over an open network.

PHP is not Java, and you will be better off long-term not trying to write PHP code as if it is Java. Packages don't exist, and classes & namespaces are entirely different mechanisms...

I haven't done much with XML before.
I'm trying to access the property "results-count" of "api:pagination" in the following XML document:

code:

<?xml version="1.0" encoding="utf-8"?>
<feed>
   <api:schema-version>3.6</api:schema-version>
   <category scheme="http://www.symplectic.co.uk/publications/atom/feeds/" term="item-list" label="Item list"/>

   <icon>[url]http://url.com/publications-api/symplectic.ico[/url]</icon>
   <rights>This feed is the property of the _____________, and can only be used with permission.</rights>
   <api:pagination results-count="713" items-per-page="10">
      <api:page position="this" number="1" href="http://url.com/publications-api/objects?categories=publications&amp;groups=33&amp;per-page=10"/>
      <api:page position="first" number="1" href="http:/url.com/publications-api/objects?categories=publications&amp;groups=33&amp;per-page=10"/>
      <api:page position="next" number="2" href="http:/url.com/publications-api/objects?categories=publications&amp;groups=33&amp;page=2&amp;per-page=10"/>
      <api:page position="last" number="72" href="http://ref.cam.ac.uk:8090/publications-api/objects?categories=publications&amp;groups=33&amp;page=72&amp;per-page=10"/>
   </api:pagination>
</feed>
</xml>

I've tried using simpleXML and DOM but just can't work out how to access that specific data.
For example, at the moment I have:

php:

<?
$xml = new DOMDocument();
$xml->load("publications.xml");
$pagination = $xml->getElementsByTagName("api:pagination");
echo 'length: '.$pagination->length;
?>

Which shows the length as 0.
What am I doing wrong?

Edit: upon further investigation, it looks like this has something to do with namespaces. Time to do some reading...

Edit 2: resolved, needed to use GetElementByTagNameNS with the url of the namespace.

I'm trying to create a completely separately deployable module of PHP that I can include in different contexts. In order to do that, it seems like I have to create a custom autoloading function that will be able to find my classes no matter where they are included from.

I'm working on an autocomplete for SSN-like numbers. So if they search for '123', it should find the number 444123555. I want to bold the results, thus, 444123555. I then, however, want to format it as an SSN - thus creating 444-12-3555.

Is there some way to say 'put the dash after the nth digit' in PHP? Because I don't want the nth character, just the nth digit - if I could say 'put a dash after the third digit and the fifth digit, ignoring non-numeric characters like <, b, and >' that would be awesome. Is this doable in a regex?

Maybe something like this, where it matches 3 numbers with any amount of non-numbers interspersed:

code:

$str = '444<b>123</b>555';
$pattern = '#^'
  .'((?:[0-9][^0-9]*){3})'
  .'((?:[0-9][^0-9]*){2})'
  .'((?:[0-9][^0-9]*){4})'
  .'$#'
;
$str = preg_replace($pattern, '$1-$2-$3', $str);

echo $str;
//string '444<b>-12-3</b>555' (length=18)

Top of my head: split the string based on a regex with preg_split(), then join the resulting array back together with implode using '-' as the glue.

Or go to town using preg_replace().

After you've found it, add the dashes and do something like this?

code:

$ssn = '12-345-6789';
$search = '456';
$pattern = preg_replace('/(\d)/', '${1}-?', $search);
$search_result = preg_replace("/($pattern)/", '<strong>${1}</strong>', $ssn);

Got a couple of questions for ya'll if you wouldn't mind.

Was helping a customer out at work who was having issues installing the MongoDB extension for php. It kept throwing this error when running pecl install mongo:

code:

shtool at '/tmp/pear/temp/mongo/build/shtool' does not exist or is not executable.

This is on a Debian Squeeze box and php5-dev was installed. I was at a total loss for why it was happening, and didn't find any helpful info from googling around. Only real pertinent info I have is that the directory /tmp/pear/temp/mongo directory existed, but it was empty. Curious if anybody has any insight into why this error was getting thrown.

Second question. I'm teaching myself php and am trying to figure out how to parse XML. I've taken a look at the documentation for parsing XML, but I'm hoping somebody can point me in the right direction of something beginner friendly.

The user you are trying to install it as probably doesn't have permission to execute scripts that are in /tmp. Google found me this: http://www.php.net/manual/en/apc.installation.php#104496

We have code that odbc_connect()s to an off-site database. It then, of course, gets the data one line at a time, odbc_fetch_assoc() style.

Is there any way to shotgun that data? Say, "Get every single row, all at once, and save it to this file?" Because the connection between us and them has become a bottleneck and I'm looking for any way to improve it beyond "get a row, write to a file, repeat".

I believe so, what would I do?

Edit: PDOStatement->fetchAll � Returns an array containing all of the result set rows hm!

Except it doesn't let me dump to a file, it pulls into an array... and considering some of these results sets are multi-gig, I doubt I have the memory to handle that. And because their data is ... well let's just say we have to create primary keys for it when we pull it in, so I doubt I could just a LIMIT clause to do my bidding. Foiled again!

Followup: Looking at our network usage chart, our connections to them seem to be strictly throttled - when each connection finishes, there is a very visible and sharp stairstep in the bandwidth used.
