I know there was a TONS of similar quesitons here, but I've tried already all suggestions posted in other questions, and nothing helped.
This is my function:
function makecookie($s, $d) {
if(empty($_COOKIE[#COOKIE_PATH . "[{$s}]"])) {
setcookie(#COOKIE_PATH . "[{$s}]", $d);
}
return true;
}
At the top of the document I got: ob_start(); and at the end of the document I got ob_end_flush();.
When I try:
echo setcookie(#COOKIE_PATH . "[{$s}]", $d);
exit;
It returns 1 what means 'true'. And cookie has been not set.
So why does it happen?
Once the cookie is set, you can retrieve it on next page load with $_COOKIE["name of cookie"]
#COOKIE_PATH doesn't look like valid/sensible PHP. Are you sure that isn't some sort of typo for (say) $COOKIE_PATH?

this is my first post. So basically I am trying to make a php file that returns the value of a website.
Here's what I got so far:
<?php
function GetRank($userId,$groupId) {
$url = "http://www.roblox.com/Game/LuaWebService/HandleSocialRequest.ashx?method=GetGroupRank&playerid=$userId&groupid=$groupId";
//echo $userId,$groupId;
//$response = readfile($url); // works but returns this (READ HERE)'<Value Type="integer">1337</Value>32'
if ($response) {
return $response;
}
return 'Failure';
}
?>
<Value Type="integer">1337</Value>32
I don't want to have it returning the above, as it currently does, I wanted it to return 1337. No clue how, I never did this before.
An example link:
http://www.roblox.com/Game/LuaWebService/HandleSocialRequest.ashx?method=GetGroupRank&playerid=25608009&groupid=228876
Thanks in advance I hope u guys understand me q.q
You can use the function below which will remove html tags from a string.
strip_tags($response);
I'm fixing up some old code that is supposed to create a directory for a customer based on the customer's last name. 999 out of 1000 times it works as expected but every now and then I get an "Unable to create base directory" error message and the debug shows me that the $file_directory in that case is simply "Array" instead of something like "\\network\path\order_data\1234567890_Smith".
Could anyone explain how this code could work the vast majority of the time but still consistently fail about .1% of instances? Or is it something other than the code? Thanks!
Note: I did not originally write this code but am tring to leave it as close to the original as possible
Edit I had a typo in my previous code but I think tliokos and Fluinc had a very good point but just wanted to fix my mistake
Code:
<?php
$file_directory = build_directory($customer, $UID);
if(!is_dir($file_directory)){ //Check to make sure it does not already exist
if(!mkdir($file_directory)){
mail("debug#example.com","Unable to create base directory","$file_directory");
}
}
function build_directory($customer, $UID){
if($customer->related_orders){
$related = explode(",", $customer->related_orders);
foreach($related as $r_UID){
$rel_order = get_order($r_UID); //fetches order object
if((isset($rel_order->file_directory) && $rel_order->file_directory != "")){
return $rel_order->file_directory;
}
}
}
//Here is where I made my correction
$paths = array('\\\\network\\path');
$base = $paths[0];
//Test if directory is already assigned
if(is_dir($base . "\\order_data\\".$UID."_".str_replace(" ","_",$customer->last_name)."\\")){
return $base . "\\order_data\\".$UID."_".str_replace(" ","_",$customer->last_name)."\\";
}
if($base){
return $base . "\\order_data\\".$UID."_".str_replace(" ","_",$customer->last_name)."\\";
}
}
?>
Change $base = array('\\network\path');
To $base = '\\network\path';
I think the problem is in the build_directory() function and more specifically after the first if.
So if the customer has no related orders, you are trying to concatenate an Array with a string and the result is like
Array\order_data\....
Try o change
$base = array('\\network\path');
to
$base = '\\network\path';
So the problem ended up being framework/user related.
We discovered that if the user refreshed the page during the directory creation it would create the same directory twice which our framework would save as an array of identical paths.
I need to jump into a server side code. It is used cakephp there. I would like to see a variable, I think it is a model, but I am not sure, let be a variable in or case.
CakeLog::write('debug', 'myArray'.var_export($myArray) );
it will have the output
myArray: Array
I would like to see similar output as var_dump can produce to the output.
Is that possible? if yes, than how?
Any help apreciated.
Just use print_r, it accepts a second argument not to output the result.
CakeLog::write('debug', 'myArray'.print_r($myArray, true) );
And if you don't want new lines, tabs or double spaces in your log files:
$log = print_r($myArray, true);
$log = str_replace(array("\n","\t"), " ", $log);
$log = preg_replace('/\s+/', ' ',$log);
CakeLog::write('debug', 'myArray' . $log);
Try:
CakeLog::write('debug', 'myArray'.print_r($myArray, true));
The true parameter makes print_r return the value rather than print on screen, so you can save it.

Somebody got a redirection method presented here.
This I have used to see what I have there, and it shows very clear.
I use the latest code igniter (2.0.3) and php-active 0.0.1.
All are working fine except save();
Code:
if($_POST)
{
$entry= Customers::find_by_routeid('4');
$entry->routeid=5;
$entry->save();
}
Here's my problem: for some reason that I cannot understand the above code does not work, but if I take the code out of if ($_POST), it works fine.
What I am doing wrong?
EDIT:
Thanks Damien Pirsy $this->input->post() does the trick, but when I uncomment the comments in the code the problems returns.
The code now is:
if($this->input->post())
{
$id = $this->input->post('id');
$oldRoute = $this->input->post('oldRoute');
$newRoute = $this->input->post('newRoute');
$entry= Customers::find_by_routeid($this->input->post('oldRoute'));
$entry->routeid=$this->input->post('newRoute');
$entry->save();
/*
if($oldRoute<$newRoute)
{
for ($i=$newRoute; $i>$oldRoute; $i--)
{
$element = Customers::find_by_routeid($i);
echo $element->routeid -= 1;
$element->save();
}
}
*/
}
The elements new IDs ($element->routeid -= 1;) are echoing right, but I have the same problem as in the beginning and neither of two saves work.
You didn't provide much details or debug info, so I'll just guess: try using the CI's native post handler instead. You should have var_dump()ed the $_POST array, see if isset() or not, also, since you're using it as a condition
if($this->input->post())
{
//...
}
UPDATE:
Since we're talking about Post variables, don't assume they're exactly as you want them. Keep in mind that $this->input->post('field') returns FALSE when the index is not present; that might well brake your if condition.
Assuming you need numbers to do this, you can do a check like
if($this->input->post('newRoute') AND is_numeric($this->input->post('newRoute'))
{
$newRoute = $this->input->post('newRoute');
}
else
{
// give it a default value, or raise an error, for example. If you need this
// variables, and need them to be numbers, you cannot go on in case these
// conditions are not met, right?
}
And the same for $oldRoute.
And yeah, OK, maybe you can write a cleaner code than mine, but you get the picture ;)
<?php echo isset($areas['footer']) ? $areas['footer'] : null; ?>
Any way to improve that?
Note that you are echoing and in false condition it would be null which does not have any effect. You could say like 'empty' or ' ' or 'not found' instead. Other alternative is to get the return value of isset:
$return = isset($areas['footer']) ? $areas['footer'] : null;
if ($return)
{
// $return contains footer info
}
else
{
// footer was not set :(
}
Depending on where $areas comes from it might be cleaner to assign it to a variable:
$footer = isset($areas['footer']) ? $areas['footer'] : null;
Then you can use $footer without any additional isset checks.
You can also spare the else branch, by setting a default:
$footer = null;
if (isset($areas['footer'])) {
$footer = $areas['footer'];
}
echo $footer;
No, this is the most concise way of handling this sort of output.
"i'm using this kind of code very often"
Maybe you should avoid the issue altogether by using a template language, or encapsulating this behavior in a function?
like this:
function get_area($area) {
if... //your code
return $area
One shorter version i can think of would be:
<?php !isset($areas['footer']) or print $areas['footer']; ?>
But i'm not sure if it is faster or more elegant.
What do you guys think?
echo $areas['footer'];
Simple and has the exact same effect as the original line.
Edit in reply to Felix
This gives a notice, but unless you're supposed to turn this in as ultra-perfect homework, it doesn't really matter. You can either fill your code with isset calls or ignore small stuff like this. I'd worry about it if I was working in say... Java, but pragmatically nobody is going to care if PHP code that works produces notices.
