if so how would they be used in a mysql query?

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"; }
?>

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.

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...

Quote

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

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,

im having trouble adding a get variable to a url if one already exists.

eg

current url = http://www.example.com/index.php?var1=something

i want to be able to change this to

new url = http://www.example.com/index.php?var1=something&var2=another

even so i can have a few get variable there.

I can add the first var through a form or link, but how would i add more through a link or through the header function?

I am positivly stuck.

Thanks

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

Can someone tell me why so i can fix it?

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%) {

Working with authorize.net script that is included in my php.  Trying to figure out how to use a variable beyond the 'case' I can do just about anything... inside the case... But I need to use the variable outside of there.

Code: [Select]
//several cases above
case 5:
$this->approval_code = $pstr_trimmed;
break;

// case 7 is the authorize.net transaction ID - This is the one I want to work with
case 7:
echo "Transaction ID: ";
echo $pstr_trimmed;
$trans_id_test = $pstr_trimmed;

break;
// but this below won't work. I can't use the variable anywhere outside of the case.
echo "the new variable is now...".$trans_id_test;

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
