PHP - Variable Won't Exist Beyond Break;

Does the concept of a "Namespace" exist in PHP?

If so, how do you use them?

This is a snippet from ASP.NET that made me ask this question...

<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SqlClient" %>

Hi all -

I have a form that let's a user upload an image to their specified folder. The folder is determined by the "password" the user inputs. The "password" is really just the folder name on my server, so if "michael83" was entered as a password, the directory would be "images/uploaded/michael83". That works great now, thanks to a forum user, litebearer. Thanks again.

Here's my second question:

I'm working on a "history" page so that a user can input their "password" and view their upload history.

The form works right now. If you enter a "password" (folder name) that exists, the code will spit out the contents / files. So, now I'm looking for two things:

(1) if a user enters a "password" (folder name) that exists, but there are no files in the folder, "There are no files in the $dir directory." will be echoed; and

(2) if a "password" (folder name) is entered that does NOT exist, "The directory $dir does not exist." will be echoed.

Here's my code so far (minus the if statements I'm looking for):



$dir = $_POST['password'];
$path = "images/uploaded/". $dir;
$dir_handle = @opendir($path);

while ($file = readdir($dir_handle)) {
if($file == "." || $file == ".." )
continue;
if(isset($_POST['Submit']))

$url = "http://www.mysite.com/". $path . "/" . $file;
{
echo "<a href=\"$url\">$url</a><br />"; 
}}

closedir($dir_handle);



As always, many thanks in advance for any help on this.

hello, i am having an issue with tables using incorrect data.

Hi all,

I want to make a script that identifies if an image JPG file exists.

Would somthing like this work?


<?php
$file = "images/image.jpg";
if ($file > 0) {
echo "file exists";
}
else { echo "no file"; }
?>

Gud pm!!
So i made this script to check if a username and password exist but it kinda fails me.
It gives me a database connection error from my confirm_query() which means it returned false?
so here's my code:

Code: [Select]
  function check_if_exist($username, $password)
{
global $connection;
$query = "SELECT username, hashed_password";
$query .= "FROM users ";
$query .= "WHERE username = '$username' ";
    $query .= "AND hashed_password = '$password' ";
$query .= " LIMIT 1";
$result_set = mysql_query($query, $connection);
confirm_query($result_set);
if(mysql_num_rows($result_set) == 1)
{
return true;
}
else
{
return false;
}
}

my confirm_query():

Code: [Select]
function confirm_query($result)
{
if(!$result)
{
die("Database connection failure ". mysql_error());
}
}

I have a another script to check if the email exist and it works perfectly, i dunno why this won't work properly.. 
maybe another simple mistake..
Any ideas or Violent reaction? 
Thanks!

Hi..

So what i want to do is basicly to check if id XX exist in my database.
How can this be done?

Im thinking of something like:

if(xx exist){do this}
else{do this}

Iv'e tried google etc before i posted here, but couldent really find anything where i found a soutable answer..

Hope someone can help! (:

Basically this gets a number from a table on my DB, and displays the content relevent to that number...the second part checks for that number and gets other information according to that number...

what i want to do is make sure that the number from the first query exists in the table from the query, and if it doesn't print out and error saying "there is no information" or whatever..

anyone have an idea?

hopefully this makes sense

Code: [Select]
<?php
require_once('Connections/myConnect.php');
$detnum = $_GET['Details'];
$detinfo = mysql_query("SELECT* FROM `Agency Stores - Table 1` WHERE F11=".$detnum);
$det = mysql_fetch_array($detinfo);


$salesnum = $det['F3'];
$salesinfo = mysql_query("SELECT* FROM `By Agency Store _` WHERE store_store=".$salesnum);
$sales = mysql_fetch_array($salesinfo);

if(mysql_query("SELECT* FROM `By Agency Store _` WHERE store_store=".$salesnum)){

}

?>

Fatal error: Call to undefined function notification() in C:\xampp\htdocs\xampp\index.php on line 21


after including the functions.php file i wrote. It does include it but the data isnt being recognised from it. If i copy/paste the notification() function into index.php it works.

Can someone tell me why so i can fix it?

I need to insert data into a table if it doesn't exist or update if it does.

Can someone give me an example of this code.

im using mySQL 5.1.42
im using phpMyAdmin 3.1.o

I have a field in a table named flights
I hope to find a 1 line statement to bypass inserting a new row if $flight_no is already in the field flight_no
btw flight_no is the primary key and won't  allow a duplicate anyway but I want to avoid the error message

this is what I tried but doesn't work
if(SELECT * FROM flights WHERE flight_no !LIKE  %$flight_no%) {

what i want to do is add the details to a new multi dimensional array but only add one each like so

array(
    ['units'] = array(
          ['name'] => 'Pikemen',
          ['lost']    => 14
     )
)
basically where the HP is 0 in the first array i need to add them to the second if the name is unique. I have tried array unique but it didnt seem to work. Any ideas? All i get it a loop of each Pikemen

Is it possible to check if multiple rows exist at the same time.  For example, if a row with the id "1" and another row with id "2" exists, and return something like true then false if only the first exists?   I have a file that provides tens of thousands to check and it takes forever.  I know this sounds bad off the start, but it's not something that is run normally.  Only to update my database with new additions.   Is there any good way to check a lot at once?  I know you can insert many at a time and save a lot of time.

Here is my code so far (I say it's PDO but it pretty much isn't. What is the object here? The database connection? LOL!);
 

$sql = 
	"
	SELECT 
	SUM(IF(`sent` != 'N' , 1 , 0 )) as 'Emails Sent',	
	SUM(IF(`completed` NOT IN('N','paper') , 1 , 0 )) as 'Completed Electronically', 	
	SUM(IF(`completed` = 'paper' , 1 , 0 )) as 'Completed Manually', 
	SUM(IF(`completed` != 'N' , 1 , 0 )) as 'Total Number Completed',
	SUM(IF(`remindercount` = '1' , 1 , 0 )) as 'Reminder Sent Once',
	SUM(IF(`remindercount` = '2' , 1 , 0 )) as 'Reminder Sent Twice',
	SUM(IF(`remindercount` = '3' , 1 , 0 )) as 'Reminder Sent Thrice'
	FROM `tokens_$survey_id`
	";
				
$statement = $dbh->prepare($sql);
$statement->execute();

$result = $statement->fetch(PDO::FETCH_OBJ);
				
foreach($result as $key => $value) {
	 echo "<tr>
		<td>$key</td>
		<td>$value</td>
	       </tr>";
}

This is all well and good if the tokens_$survey_id table is actually there. Sometimes, for a genuine reason, there won't be a tokens table for that particular survey. How do I account for this? At the moment I get an error..
 

Warning: Invalid argument supplied for foreach() in /var/www/html/index.php on line 149 

I tried this but I am not satisfied this is correct;
 

if(!$result) {
die();
}

I don't want the code to die! If I take out the die() statement then this if is ignored for some reason I don't understand.
