[PHP] TextArea vs. URLEncode/URLDecode/quotes
Hello! I have a form with a textarea... When the user submits the form, I validate the form on another page.. and in case the data are not valid, I redirect the user back to the form, passing all the info filled in previously in the URL, then I easily display the values in the form again For textarea, I use : urlencode($textarea_value) to pass the text in the URL for the validating page. And in the textarea, to get back the info, I do: textarea?=urldecode($_GET['textarea_value'])?/textarea This works fine as far as there is no quote in the text In case there are quotes in the text, quotes are escaped :-( so I get in the textarea slashes just before the quotes and stripslashes doesn't seem to help... So, My question is: What's the best way to get the value of a textarea back after validation without using session? Thanks.

The correct way is:
In validate.php:
if(error) {
if(magic_quotes) stripslashes();
urlencode();
} else {
INSERT INTO ...
}
In form.php:
// urldecode() is not needed, GET variables are already decoded
if(magic_quotes) stripslashes();
textarea?= htmlspecialchars()?/textarea
Thanks!!! :-)

[PHP] GD lib. image quality!
Hello! I wrote a little script for generation thumbnails of larger images code $origImage = imageCreateFromJpeg($sourcePath./.$currentImageName); $thumbnail = imageCreate($thumbWidth,$thumbHeight);// create empty image imageCopyResized($thumbnail,$origImage,0,0,0,0,$thumbWidth,$thumbHeight,imag esX($origImage),imagesY($origImage)); imageJpeg($thumbnail, $targetPath./.$thumbNamePrefix._thumb.jpg); // Store it imageDestroy($thumbnail); // cleanup echo brImage .$targetPath./.$thumbNamePrefix._thumb.jpg. created successfully!; /code then, I've noticed that the quality of the thumbnails created is very bad! my phpinfo() page shows 2.0 or higher as GD version So, I'm wondering whether I'm doing something wrong in my code or whether there exist a better library to use with PHP ... a library able to generate good quality JPG files...

[PHP] Showing up variables in URL !

So, how to make PHP so that when I load my page in the browser(typing index.php in the adress bar) , it will print not only hello on the page,but also show index.php?greetings=hello as URL , So , I basically want PHP to dynamically append ?greetings=?=$greetings? to the URL I've typed How to do this ?

Or, so you don't have to specify all the variables you are using
as globals (especially if you are using *alot* of them), you can
use:
$GLOBALS[SCRIPT_FILENAME];
What's the gain? 'global ' has 7 characters, whereas '$GLOBALS[]' has
10 characters. So, you don't type less. And with using global(), the
code is more orderly, and thus easier to read.
True. But take the following function:
function processLotsOfFormVars() {
global $fieldOne, $fieldTwo, $fieldThree, $fieldFour;
global $fieldFive, $fieldSix, $fieldSeven;
global $PHP_SELF, $REQUEST_URI;
global $HTTP_REFERER;
echo Field One is: $fieldOnebr\n;
echo Field Two is: $fieldTwobr\n;
// etc
}
OR you can do it this way:
function processLotsOfFormVars() {
echo Field One is: $GLOBALS[fieldOne]br\n;
echo Field Two is: $GLOBALS[fieldTwo]br\n;
// etc
}
I've done it both ways. I'm not advocating using
$GLOBALS[var_name]; over global $var_name,
just that it is an alternative if you are using alot of global
variables in a function. Plus, if the function gets large,
it's easier to see where the value is coming from by using
the $GLOBALS variable.
That's all I was saying.

Re: [PHP] PHP_SELF or REQUEST_URI within Function ?
Cool ...
Now that we're talking about PHP
I'd like to ask a question
You know the overloading function in C++ Is that possible in PHP ?
Basically , I'd like to define more than one function having the same name
but different number of variables/parameters ... so PHP would know which one
I'm calling depending on the numbwer/type of the variables ...
exemple :
?
function arcad_func( $var_a )
{
echo $vara ;
}
;
function arcad_func( $var_a , $var_b )
{
echo $vara . $var_b ;
}
?
?
arcad_func(Hello!);
arcad_func(Hello , World!)
?
Would this work ?
Thanks...

So sprach »Boget, Chris« am 2001-08-31 um 10:22:28 -0500 :
True. But take the following function:
function processLotsOfFormVars() {
global $fieldOne, $fieldTwo, $fieldThree, $fieldFour;
global $fieldFive, $fieldSix, $fieldSeven;

echo Field One is: $GLOBALS[fieldOne]br\n;
echo Field Two is: $GLOBALS[fieldTwo]br\n;

Uh? I don't see it. The matching function 1 is:
function processLotsOfFormVars() {
global $fieldOne;
global $fieldTwo;
echo Field One is: $fieldOnebr\n;
echo Field Two is: $fieldTwobr\n;
}
this quite doesn't look as intimidating as the piece you wrote. And
even if there are 10 lines of 'global', I still like it a lot better,
because it CLEARLY shows which form vars are going to be used.
One of the downside of PHP IMHO is, that you do not have to define
variables. This leads to a lot of errors. At least there should be a
option, which forces you to define variables, like maybe so:
dim $some_var;
this leads to easier readable code IMHO.
variables in a function. Plus, if the function gets large,
it's easier to see where the value is coming from by using
the $GLOBALS variable.
Now, that's the point I'm arguing here. I don't think so.

I am having the problem in the coding below

$temp = $username.watch;
$watchlist_query = mysql_query(Create Table $temp(WId int Not Null

So.. in the above coding. I need to create a table. The table name
should be a user-define name + watch
I acquire the $username correctly and the variable $temp is working fine
when I try to echo the value of it.
Just say. I enter my username as coconut so I wish the mysql query to
create a table called coconutwatch
but I can't do that.. Because of the syntax error, the coding I have
underline is where the parser told me that is an error there.
I have playing around with it for 2 hours and more... but I cant solve
it.. Anyway help is greatly appreciated.
Thanks in advance.
