[[SOLVED] Parse Error, syntax error - big page, warning]

Ok I have been told this before, but in such a way that it just goes right over my head.

 

(I have always learn that " " for strings, ' ' for ints, but I can't use " " so I went for ' ' but this also doesn't work in this case).

 

So for things like SESSION and POST, inside the square brackets, should I always try and use quotes of some sort, but why?

 

 

Thanks if you can explain in simple Lokolo terms

 

 

p.s. omg why did i not see it, the lines below have the quotes taken out of them ARGH

[[SOLVED] Parse Error, syntax error - big page, warning]

http://pastebin.com/m66e4c3a0

 

I pasted it on there.

Now I have counted the {'s brackets and its not that, but I cannot see anything else.

 

I just thought 2+ heads is better than 1.

 

Its line 14 btw. (although my actual page is a lot larger but I thought I only needed that part).

 

Thanks for any help

[[SOLVED] PHP not installing hmph]

I am on Vista by the way, just before I explain the problem.

 

ok so I have installed Apache 2.2.4 and this all works (I can get onto http://localhost and it says "It works"). Now I am trying to install PHP 5.2.4 and I put everything correctly to my knowledge, however, at the end of the installation it did say there was a script missing, which is what I was thinking is the problem, so I cannot load PHP files.

 

From a few installation tutorials it seems the PHP should add something to the httpd.conf but I am not sure what, the "Load" thing but I am not sure what the actual command is.

 

Also I have 2x httpd.exe processes running, is this right? (ones 1,856k, the other 4,388k)

 

So anyone could help?

[[SOLVED] Function in a Function - value not returning]

i had tried to return thing but that didn't work either.

 

it was the == thing. thanks everyone

[[SOLVED] Function in a Function - value not returning]

hm

 

i keep doing this. its not even funny anymore. im use to other programming. i'll try that but not sure if it'll work. (as you can see in the other if statement below i did use == rather than = so i do know some things hehe )

 

i'll try that out

[[SOLVED] Function in a Function - value not returning]

This is my function:

 

function filenamecreator(&$newfilename)
{
	$chars = "abcdefghijkmnopqrstuvwxyz023456789";
    	srand((double)microtime()*1000000);
    	$i = 0;
    	$newfilename = '' ;
while ($i <= 7) {
        $num = rand() % 33;
        $tmp = substr($chars, $num, 1);
        $newfilename = $newfilename . $tmp;
        $i++;
    }

 

I can use it in the main program it works

however i use it in another function, the code used below

 

$flag = 0;
	while ($flag = 0)
		{
			$flag = 1;
			filenamecreator($newfilename);
			$get_otherfilenames = mysql_query("SELECT * FROM logfileinfo");
			$num=mysql_numrows($get_otherfilenames);
			$count = 0;
			while ( $count < $num )
				{
					$otherfilename = mysql_result($get_otherfilenames, $count, "filename");
					if ( $newfilename == $otherfilename )
						{
						$flag = 0;
						}
					$count++;
				}
		}
	$add_logfile = mysql_query("INSERT INTO logfileinfo (hotelID, filename) VALUES ('$hotelID','$newfilename')");

 

However, its not adding $newfilename as anything (i.e. its "")

 

Hope someone can help!

 

Thanks

 

 

[PHP and Files]

ah. they user doesn't upload it. I create it!

 

i create and update the log. the only things they can do are download and upload.

 

the only thing I can now think of is create a MySQL table with the hotelID and Encryption

 

i create the encryption completely randomly, check if one already exists (just incase), and then store it.

 

hotelID    Encryption

1              ab5nsj478sn

2              384jfn39jd0

3              83ncnc93j9

 

so files would be ab5nsj478sn.txt , 384jfn39jd0.txt, 83ncnc93j9.txt

 

then when updating/downloading etc. I can just get the encyrption from the table.

 

Thoughts?

 

(I would use your code but I am not exactly experienced! )

[PHP and Files]

Ok so I have some code

 

	case "Download Log":
	echo "Downloading... <br><br>";
	rename("$_SESSION[hotelID].txt", "log.txt");
                //download file
        break;

 

but I am not sure how to get it to download the file. (on the //download file bit).

 

_____________________

 

the next thing. as you can see from the above the files are based around the hotelID. how can I stop people typing www.url.com/1.txt and then gaining access to the files? (if this is possible) - I was thinking of having the hotelID go through some sort of algorithm like (*56 + 50)*4 to make the file name (so ID 1 would be file 424.txt - am I thinking correctly?

If so how could I encrypt it better, such as adding letters to the name.

Wow long,

 

should be simple enough for the uber programmers,

 

thanks,

[[SOLVED] Passing value back through a function]

Passing by refence is done by putting an & sign in the fucntion define

 

i.e.

 

function(&$variable)

{

}

 

will pass it back. for anyone that wants to know.

[[SOLVED] Passing value back through a function]

I can't figure out how to do it.

 

so if i have this code

 

$count = 5;
somefunction($count);
echo "$count <br>";

--------------------

somefunction($count)
{
$count = 1000;
}

 

but obviously the echo will print off 5, not 1000, which is what I want.

w3schools goes on about the return syntax but that only works when the function is returning 1 value!

 

hope you can help (and understand what I am on about),

[Numeric Comparing giving wrong answer]

ok will try that.

 

however, i got it to work by removing the

 

	echo "$_SESSION[totalcost] <br>";
	echo "$_SESSION[funds] <br>";

 

statements, as a PHP Expert (you seem to be answering everyones questions with ease) why could this be?!

 

[edit]

your way worked. hm i deleted a few statements and it didnt work again, so used yours, and harruh!

[Numeric Comparing giving wrong answer]

	echo "$_SESSION[totalcost] <br>";
	echo "$_SESSION[funds] <br>";
	IF ( $_SESSION[funds] < $_SESSION[totalcost] ) {
		echo "You do not have enough cash to upgrade <br>";
	} ELSE {
		echo "Upgrading... <br>";
	}	

 

Output:

 

75,000

622,500

You do not have enough cash to upgrade

 

I have no idea why. What reasons could it be?

[[SOLVED] 2x !isset($_POST['submit']) - how to get it to work?]

hidden thing worked. thanks!

[[SOLVED] 2x !isset($_POST['submit']) - how to get it to work?]

indeed - i tried that but it then just goes back to the first form. obviously that value of submit is wiped as soon as i touch the 2nd form. (if you understand me)

 

not sure how i can get around this though

[[SOLVED] 2x !isset($_POST['submit']) - how to get it to work?]

ok basically i have 2 forms, one shows up at the start, that gets submitted and the page refreshes wth the 2nd one.

 

however, i cannot figure how to submit the 2nd one as the forms are both submit forms.

 

(basically once i submit the first one, it then goes to the elses of both. i can get the 2nd form to display if i change the 2nd !isset($_POST['submit']) to something else but then i can't submit that one)

 

        <?
if (!isset($_POST['submit'])) {
	?>
	<h2>
	<form action="<?php echo $_SERVER['PHP_SELF']; ?>" 
		method="post" 
			onsubmit="return checkSubmit(this);">
		Number of Rooms: <input type="text" size="3" multiple style="height: 20px" maxlength="2" name="numrooms">
		<input type="submit" name="submit" value="Upgrade">
	</form>
	</h2>
	<?
} else {
	upgradehotel($_POST['numrooms']);
	if (!isset($_POST['submit'])) {
	?>
	<form action="<?php echo $_SERVER['PHP_SELF']; ?>"
				method="post" 
				onsubmit="return checkSubmit(this);">
		<input type="submit" name="confirm" value="Yes">
		<input type="submit" name="confirm" value="No">
	</form></h2>
	<? 
	} ELSE {
	echo "work damnit work";
	}
	?>

 

heh thanks!

[[SOLVED] 101000 --> 101,000 (i.e. big numbered currency)]

oh nice one, guess i gotta learn those good old string functions...

[[SOLVED] 101000 --> 101,000 (i.e. big numbered currency)]

Currently in my DB table i store the funds as a numeric so 1000, or 101000 - but how do I put a comma in?

 

Simple as really but no idea how to do it heh.

 

thanks,

[display image if field =]

ok if you have the url in a field then thats all good

set the url to a variable so like $url

 

then do the regular image thing with HTML

 

so like <img src="$url">

 

(I think)

 

so

 

if ( field = 1 ) {

<img src="$url">

} else {

echo "you do not have priviledges to have a picture";

} ;

[[SOLVED] UPDATEing setting # to 0 instead of $var]

it doesn't matter now - i figured it out - it wasn't keepin it as a numeric, sorted it now though

[[SOLVED] UPDATEing setting # to 0 instead of $var]

ok using the above code (fixed - i missed mysql_query - i don't know what i was thinking, as i said, very tired )

 

however the echos gave:

 

Array

0

 

hm ignore the Array thing - i have typed in the wrong variable name LOL.

 

the 0 however, is the stored value for the new stayinglegnth - which shouldn't be 0!!!!! RAR

[display image if field =]

if ( field = 1 ) {

display image

} else {

don't display image

}

 

 

[Difference Between ' " `?]

ok from what I know (not a lot but still)

 

you use ' around variables

you use ` around table names

and you use " around commands (such as echo "hello" or "SELECT...." )

 

 

[[SOLVED] UPDATEing setting # to 0 instead of $var]

i am getting mysql fetch array error now hm

 

	
$get_newvalues = ("SELECT * FROM `rooms` WHERE roomID = '1'");
$funnyrow = mysql_fetch_array($get_newvalues);
$thevariable = $funnyrow['stayinglength'];
$secondvar = $funnyrow['guest'];
echo $funnyrow;
echo $thevariable;	

 

on '$funnyrow = mysql_fetch_array($get_newvalues);' <-- that line

 

i know im being a n00b but my brain hurts

 

thanks,

[[SOLVED] UPDATEing setting # to 0 instead of $var]

nope 4. using phpdev and that came with mysql4 and phpmyadmin 2.3.2

 

um, well what i did before was

 

$updatedstayinglength = $stayinglength - 1

 

i thought that would keep it as a numeric - obviously not.

 

anyway or sorting this out? (i have no idea - a link will do if you don't want to explain)

 

thanks,

 

Lokolo

[[SOLVED] UPDATEing setting # to 0 instead of $var]

$update_guestsstaying = "UPDATE `rooms` SET stayinglength='$updatedstayinglength' WHERE roomID='$roomID'";

 

 

ok its setting the stayinglength to 0 when roomID = '$roomID' instead of setting it to the $updatedstayinglength

 

i can echo $updatedstayinglength and it will give the number 4 for example, yet when i run that it updates it to 0.

 

I know its most probably the most obvious thing but I have been snipping/changing etc. for an hour now and cannot see why its not updating it to the variable.

 

Thanks,
