[PHP] Re: PATH INFO urls - replacing GET syntax
Navid,
The path info technique is moderately well known. I thought I'd seen an
account of it at phpwizard.net, and I would have given you the link, but
when I looked just now I couldn't find it. Anyway, this is roughly how it
goes:-
Background
You can add all kinds of stuff at the end of a url pointing to your php
script and the php still gets run e.g.
http://www.mysite.net/myscript.php/this/and/thatand_the_other
will still cause myscript.php to be run. Anything appearing after the path
name is know as the path info and is available in a pre-defined global
variable $PATH_INFO, (at least with Apache). In this example $PATH_INFO
would be "/this/and/thatand_the_other", (note the / at the front).
Basic Technique
===
So you can use PATH_INFO to communicate with your script from a link without
using a GET string e.g.
instead of : /myscript.php?search=findthis, you could just have
/myscript.php/findthis.
With the first, "GET" syntax, php automatically sets $search to "findthis".
If you use the second, path info syntax instead, then you have to do a bit
more work to get the value into the variable you want. In this case, you
would do something like:
list($null,$search) = explode('/',$PATH_INFO);
>From this line on, it's exactly as if $search was set from the GET
information.
(The $null variable is simply there to "use up" the empty variable that
explode assigns for what appears before the first /, it is only necessary
because I use list() syntax to do all the work of unpacking and assignment
in one line. list($search) = explode('/',substr($PATH_INFO,1)); would be an
alternative that avoids this dummy variable.)
You can pass any number of parameters, but your script needs to know what
variables need to be set and in what order, which it doesn't have to do
with the GET, since the names of the variables are passed as well as their
values on a GET. For example, I've had urls that look like something like
this:
/product.php/cookers/range/belling
as a replacement for
/product.php?section_code=cookers&type_code=range&manufacturer_code=belling
To unpack the PATH_INFO version in this case, I use the following code:
list($null,$section_code,$type_code,$manufacturer_code) =
explode('/',$PATH_INFO);
That's about all there is to it.
Eliminating the .php
=
There is a further refinement that I like, which is to get rid of the .php
on the end of the script name. So
instead of/myscript.php/this you have just /myscript/this, or in my
last example :
/product/cookers/range/belling. To achieve this you need to tell your
web-server that it should treat files with no extension as if they were php
files. If you run Apache, you need the following directive in the
configuration file.
DefaultType application/x-httpd-php
(Don't assume I've got the syntax exactly right, check it!)
You can set it across your whole server, just some virtual servers or
individual directories. This tells Apache that if a file has no "type" i.e.
no extension, treat it as php.
The Advantages
===
Why bother using PATH_INFO, since it is extra work?
1. Elegant URLs
Like you, I much prefer elegant urls. My reasoning is that the "location"
of a page has an extremely prominent position within any browser, so it
ought to be made as attractive, straightforward and unfrightening for the
user as possible. It's as much a part of the design as the rest of the
page. Whenever I see horrendous urls, (and some of the supposedly most
professional sites are the worst), I get a bad taste in my mouth. I
immediately assume that if the location of the page has such unnecessary
geekery, there is probably a lot more unnecessary geekery to follow on the
body of the page...
2. Search Engines
An often quoted reason for using PATH_INFO is that search engines will not
follow links which include GET data, whereas they will always follow
PATH_INFO based links since there is no way they can distinguish them from
"real" static links. In principle, this means that you can get every page
of search results indexed and treated as if it were an individual static
page by the search engine. You just need "hidden" path info based links on
your pages that point to searches for "all" or various sub-sets of the
possible results. But search engine placing is a black art, so don't take
my word for it ;)
3. Usability
Another point, is PATH_INFO urls are generally easy to
remember/bookmark/manage, since they have a simpler format and will always
use less characters than the GET version. They are, for example, much more
likely to be fully visible in the browser's message toolbar during hovers
over links.
4. Multi-Output Services
There is a more subtle long-term advantage in eliminating the GET portion of
your urls. Pure "PATH_INFO" urls are inherently more standards compliant
than urls with GET information. They are significantly more likely to fit
in with non-html urls, e.g. satisfying wap or xml requests for "data" from
Re: [PHP] zend studio 2.0
Zeev, If you find that GUI tools are not overwhelmingly better for C++, Java product development, that does weaken the case for php studios even more. Why so? 1. Conciseness of php php is a high level application development tool so the code is, or at least, should mostly consist of highly specific encapsulated business logic. This is relatively more suited to a general (possibly "application" progammable) text editor rather than a php-specific studio. 2. The other code php is mostly about integrating "other" code i.e. html/sql/Javascript/xml/pdf whatever. In the overall application these are just as important as php. The php studios seem to do a good job of bundling in sql and html tools but it's always going to be hard for one studio, however well designed, to cover the needs of several languages. 3. Maintenance vs Development Personally, I've never understood that there are distinct development and maintenance activities. Isn't maintainability the key quality issue for all code? And isn't the best way to ensure maintainability to make sure the developer maintains? In any case, php progamming is particularly likely to be mostly about maintenance. For all the right reasons: good match to business needs = more sensitivity to business needs = more changes; more robust applications = longer life = more changes; easy coding = easy changes = more changes; shorter development cycles = more prototyping = more changes. So there's lots of "maintenance" style work (i.e. small, short edits) relative to development. Once again this probably favours less structured development tools. 4. Unix Development Platform If my own development platform was Microsoft, I'm sure I'd need a development studio, if only to do all that opening and closing of windows. But if you can have X hundred windows open on K different desktops with G different tools, it isn't such an issue. 5. Testing on Live Servers Even with all these disincentives I'd still be very tempted to use a php development studio, especially for debugging, but the killer problem is how I test code. Typically, even unit testing is done on test domains/databases of live public servers. The advantage is that it greatly reduces the need for deployment/performance testing (and nasty last-minute deployment issues such as discovering you haven't got a live gd library with png). It also means it's very easy to get the end users/customers involved in testing early on and you don't have to worry about setting up access to lots of different platforms for third-parties e.g. html developers. The disadvantage is that there's always a firewall in the way, so it's not so easy, or desirable, to run back-door client connects to sql, debug or even ftp! (Before anyone jumps down my throat on security issues, why else do we have execution timeouts, user aborts, includes from outside document root etc., etc., unless it's to make this sort of thing possible? And isn't it better to have to focus on security right from the start of development?) I guess the bottom line is... Darned if I can see how anyone can make money out of php add-on tools, even top-notch development studios :( php is just too good! George P.S. On the other hand, if someone was asking for sponsorship to make 0.7 + 0.1 == 0.8, I'd get the cheque book out right away... Zeev Suraski wrote: > At 05:02 18/02/2002, Peter J.

Re: [PHP] uploading files | how to avoid submitting twice?
In JavaScript define varaible which is global for this page, name it
like page_submited, by default set it to false. On submit event set
this variable to true and then from JavaScript submit form. When user
second time will try to submit the form do nothig, just leave function
code. Your JvaScript code is enabled durring your html page is in
browesr so it will have to work. I suppose there isn't any other solution.
Here is simple code
form_submited = 0;
function submit_only_one() {
if ( form_submited ) {
return 1;
} else {
form_submited = 1;
document.forms[ 'name_of_your_formform' ].submit();
}
}
I hope I didn't make any JavaScript code errors, I didn't use it for
long time.
Good luck

I've never tried it, but it may also be possible to disable the submit
button once it has been pressed once to stop the second upload e.g.
function submitonce()
{
if (document.form.submitted.value == "No")
{
document.form.submitted.value == "Yes";
return true;
} else {
alert("Please wait...");
return false;
}
}
N.B. I've set the form's OnSubmit and the submit button's onClick, only
because I'm not sure which will work best.
I'd expect this to work with a normal form submit but maybe file upload is
funny...

[PHP] GD - dynamic PNG generation
I'm currently using the GD extension to generate dynamic PNG's containing text, that should eventually be coming from a database. the deal is, it seems to take a long time, which is probably my own fault, seeing that I'm generating so much text. I am generating an image containing approx 160 lines of text, and it takes about 20seconds to create, this unfortunatley is too long for me. I was wondering if this is a common time with GD or if I am doing something wrong. Coding wise, I currently read the text in from a file, then put the text into an array, each line being a seperate entry in the array. I then create a PNG image approx 490*1848(i change the image size depending on the amount of text). I dont do anything really strange in my image function, apart from performing a wordwrap on the text before i start displaying it, just to make the image readable. ideally I would like this to come in considerably quicker. that said, if this is going to be used, it will probably done as a cron job, so if need be I will have toaccept it being super slow. any help is appreciated bros Conor -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] form submission error trapping
Navid,
$SCRIPT_NAME is sometimes a safer alternative than $PHP_SELF.
The difference is that $PHP_SELF includes $PATH_INFO while $SCRIPT_NAME is
just the name of the actual script running.
http://www.php.net/manual/en/language.variables.predefined.php
This becomes particularly important if you use $PATH_INFO to implement
elegant (and search-engine safe) urls e.g. /search/products/myproduct rather
than /search.php?category=products&key=myproduct.

I'm not quite sure what you are trying to do. Javascript is executing on the
browser, php executes on the server, therefore to get anything from the
Javascript to php your browser will have to communicate with the server via a
request. This could be a form submission, which might be a POST or a GET.
Alternatively, it is also possible to send data to a php script via a url e.g.
myscript.php?myfield=myvalue. That means that wherever you can get Javascript
to cause the browser to issue a request for a url, if the target at the other
end is a php script then you can send data to that script.
I don't know what you are trying to do, and this is all pretty obscure stuff,
but you could for example put a hidden 1x1 image in the page and then get your
Javascript to change the location of this image to be a php script with a
variable passed on e.g. something like
dummyimage.location = "/myscript.php?myfield="+myjsvalue;
As long as you get the php to send back another empty 1x1 pixel, e.g. via a
header("Location: 1x1pixel.gif"), then your browser page will stay the same as
ever.
As it happens I do sometimes do just this in Javascript but it's to get a new
dynamic image back without reloading a page. Go to
http://tandridge.cpfc.co.uk/tables/0222/graph/2/d7 and then select something
different in the Team 1 or Team 2 selection box, and watch the graph at the
bottom of the page to see this happen. In the source look for the Javascript
function chteam_id() to see how it's done here.
Good luck,
George

[PHP] MM Dependency Problem
Hi Trying to install Troels Arvin's php distro on Redhat 7.1 with the default Rackspace setup. When I try to install his mm package, I get the following error: >> rpm -Uvh mm-1.1.3-6.arvin.rh7.1.i586.rpm >> error: failed dependencies: libmm.so.11 is needed by apache-1.3.22-1.7.1 This occurs even when Apache is halted. But if I try to install his mod_php package, I get: >> error: failed dependencies: libmm.so.1 is needed by mod_php-4.0.6-10.arvin.rh7.1 Can anyone explain what this is, and how to solve it?

RE: [PHP] Guestbook question
This example generates previous/next links but could be modified to make
links to page 1, 2, 3, 4, etc.
This code is not tested what so ever, but it should look something like
this:
-
$rows_to_show = 10;
$total_rows = mysql_num_rows(mysql_query("select name, post from guestbook
order by id desc", $db));
$result = mysql_query("select name, post from guestbook order by id desc
LIMIT $offset, $rows_to_show", $db);
while ($myrow = mysql_fetch_row($result)) {
echo "$myrow[0]\n";
echo "$myrow[1]\n";
++$counter;
}
if ($offset > 0)
echo "Previous";
if ($offset < $total_rows)
echo "Next";
-
Call the page with myscript.php?offset=0
Good luck

[PHP] Substr + Text + HTML - Problem
Hi, I still have one problem, which seems to be not solveable in a easy and smooth way: I have a text file like this: $text="This is a html extended textwhich needs to be cut after 100 chars"; Than I do a substring to limit it to only 100 words (teaser-format): $teaser_1=substr($text, 0, 100); $teaser_2="...[click here for more]"; The Output of $teaser_1 will sometimes be like this: "This is a html extended textwhich needs to be cut after 100 chars is displayed as http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Re: form submission error trapping
Jason,
You didn't mention Javascript checks.
Personally I really dislike having to wati for a page to reload before finding
out that I've just failed to fill in a field. The Javascript to do basic
on-page checks is all pretty simple stuff.
Of course this doesn't mean we can skip checking the data again in the php!
Javascript might be switched off, we might have a bug in the Javascript (easy to
do), or we (or someone else) might want to simulate form entry via a url link.
It's also quite likely that there may be checks e.g. checks for duplicate
entries, which cannot be done on a form.
Here's some skeleton code that handles a basic form with both php and javascript
checks, (I've deliberately tried to keep the php/Javascript as similar as
possible). You can try it at http://www.whiffen.net/simple.php if you want.
*** simple.php***
if (isset($surname))
{
$errormessage = "";
if ($surname == "")
{
$errormessage = $errormessage . "
You must enter a value for surname";
}
if ($age <= 0 or $age != floor($age))
{
$errormessage = $errormessage . "
Age must be a whole number";
}
if ($errormessage == "")
{
// do whatever you have to with the data and maybe finish with
// a redirect to a success page
}
}
print '
