Hi, I've been scratching my head for a while now about how to do this, I'm relatively new to php and mysql and perhaps foolishly taking on creating a user area for a website.  I have everything else working, all of my register account functions and confirmations and all of the login scripts etc. 

I have created a profile page which returns various information to the user (this bit works fine) and I've got some nice show/hide toggles running with some javascript/css but my intention is to allow the user to change thier information (e-mail address, contact phone number and also whether they are subscribed to the e-mail list), it also displays any support tickets or messages.

So after the long intro, here's what I'm struggling with...  I have a form in a visibility toggled <div> which submits a 'change_email' script, so a user wants to change their e-mail, clicks on change, the <div> appears, they bang in the new e-mail and hit submit.

My php script appears to work (because it doesn't throw up any errors), until you realise that actually it's not updated the record in the db...

I'm using mysql_query("UPDATE users SET email='$new_email' WHERE username='$user'");

Do I need to setup variables for all of the information in the db (name, username, password, email, contno etc etc) and include them in the command to get it to work or should that just pick the correct record and then update it? If that is the case is there a way I can include 'blank' variables so I don't have to set them all up...

e.g.  mysql_query("UPDATE users SET user='',password='',email='$new_email', etc WHERE username='$user'");

Many thanks in anticipation

I have a shoutbox my friend made, and I'm just adding onto it.

I have command that are like @prune, @prunelogs, @logout, etc.. I am tying to make it so you can type @ban username, @unban username, etc..

Here is my command that my friend came up with.
if($_POST['text'] == '@ban'.$username.'') {
$unn=$idk['username'];
mysql_query("UPDATE users SET banned = '1' WHERE usernane='$unn'") or die(mysql_error());
mysql_query("INSERT INTO chat (`log`, `date` ,`username` ,`text`) VALUES (1, NOW( ) , '".stripslashes($_SESSION['user'])."', 'has banned '$unn'.');") or die(mysql_error());

I've created a login page in Dreamweaver and there is a redirect page for login success and login fail. What I want to have is a selection of screens based on a data field held in the user security table.
Each security record will have up to 5 different security codes e.g. code1, code2 etc. If a code e.g. TA40, appears in any of the 5 code fields then I want the user directed to one page, if code TA41 appears in any of the 5 code fields then I want them directed to another page.
The user code will only appear in one of the fields, but can appear in any of the 5 code fields.. How can I incorporate this in to the login screen logic, as currently it will just show the follwoing

if (isset($_POST['opno'])) {
  $loginUsername=$_POST['opno'];
  $password=$_POST['pass_word'];
  $MM_fldUserAuthorization = "";
  $MM_redirectLoginSuccess = "/menu.php";
  $MM_redirectLoginFailed = "/loginform.php";
  $MM_redirecttoReferrer = false;
  mysql_select_db($database_Hanson, $Hanson);

I have created a tar file with my site backup and I assume it is the full backup.  Not sure becasue I can't "un"-tar the file.

I have tried several ways to "unzip" or untar the file but can not come up with anything.


here is how I had created the tar file:
Code: [Select]
$date = date("m-d-Y");

// repeat this command for multiple backups, changing the path - e.g. you can have a backup for email, another for files, etc.
shell_exec("tar cvfz file_backup_$date.tar.gz mydir/ ");

now how do extract it?

Hi,

I'm having a weird issue when I try to run PHP scripts from the command line on my server.  I'm trying to just run a very simple script to test it out:

#!/usr/bin/php-cgi -q
echo "Hello terminal\n"; 

And I get the following error in the terminal..

Code: [Select]
Error in argument 1, char 3: option not found
Usage: php-cgi [-q] [-h] [-s] [-v] [-i] [-f <file>]
       php-cgi <file> [args...]
When I try taking out the quiet (-q) parameter, I get the following error..

Code: [Select]
-bash: ./socket_server.php: /usr/bin/php-cgi^M: bad interpreterNo such file or directory
As you can see, in the second example, a rogue "^M" was appended to the end of the first line of my socket_server.php file.  What does ^M correlate to?  I realize it is a character code for something that can't be represented with an actual character, but I don't know what it is, and I'm not sure why it is being appended to the end of my first line.

My assumption is that this is happening in the first example too, which is why I get the "error in argument 1" message, since undoubtedly -q^M is an invalid argument...

Any help is greatly appreciated!

I know that php has a function that can execute ping command but i'm not sure how it works.
I am trying to get the result of the ping command to determine:
IP address has a reply (PC/device is turned on) IP address has no reply (ip address is vacant and not assigned to any pc/device IP address has a response (PC/device is turned off)
is this "do-able" in php??

this is my script:
Code: [Select]
function ping($ip){
// #5882FA blue color indicates Fiber Module
// #FACC2E orange color indicates cascade/uplink cable
  // #81F781 Green color indicates connected/turned on
// #FE2E2E Red color indicates disconnected/turned off
// #585858 dark gray color indicates connected patch panel port is vacant at user side

if($ip=="Cascade" OR $ip=="Uplink"){
return $status="style=\"background-color:#FACC2E;cursor:pointer;\""; /* orange */
}elseif ($ip=="Fibre Module"){
return $status="style=\"background-color:#5882FA;cursor:pointer;\""; /* blue */
}elseif ($ip==null or $ip==""){
return $status="style=\"cursor:pointer;background-image:url(images/x.gif);\""; /* dark gray */
}else{
$str = exec("ping -n 1 -w 1 $ip", $input, $result);
if ($result == 0){
return $status="style=\"background-color:#81F781;cursor:pointer;\""; /* green */
//return "on";
}else{
return $status="style=\"background-color:#FE2E2E;cursor:pointer;\""; /* red */
//return "off";
} 
}
}

i can get it display on or off and i've tested it working. but i just can't figure out if i could use this command to determine if the IP address is vacant or unassigned. I'm using this for a IP list inventory system built in PHP. I have careted a page where the the 3com switch is drawn in tabulated format with each port assigned (via PHP) to the corresponding IP address of the device/PC and indicates the port color as described in the above function. Surprisingly it works well for this switch inventory. I just want to create another page for IP address inventory using the same function. To put is simple i want to have the same function as the sofware "Advance IP-Scanner" which does the same thing as well only thing is my resources are limited to PHP (WAMP).

any help guys?

hello, i was wondering if there is a way to have a link do a command, but not to goto a page.   my reason being is that the music player software i use has a built in web server and if you goto a certain page, it will process that command.  so right now, i have an iframe that i do a target to.  its pretty mickey mouse, but its what i knew how to do.

thanks

Is there anything in php that let's me SWAP  2 arrays?

like let's say I have

3,2,1  in a array,

is there a way I can swap the 2 and 1 if a statement is true?

It was suggested that I add a ‘report’ parameter to the code, after revising with the ‘scale2ref’ code which appears to prevent the video from uploading/proceeding:

$ffmpegCommand =''.$ffmpeg_b.' -y -i '.$video_file_full_path.' -i '.$watermark_image_full_path.' -filter_complex "[0]scale=426:-2[vid];[1][vid]scale2ref='oh*mdar':'ih/10'[wm][vid];[vid][wm]overlay=5:5:format=rgb,format=yuv420p" -vcodec libx264 -preset '.$pt->config->convert_speed.' -crf 26 -report'.$video_output_full_path_240.' 2>&1';
$shell = shell_exec($ffmpegCommand); 

I couldn’t see where the -report parameter was supposed to output (error.log has a filesize of 0). So I was asked to “run command from the shell and check”?

But, I’m not sure what command and where/how to do that.

I tried adding this to the php code, and attempted to upload again, same result

echo shell_exec("/usr/local/bin/ffmpeg -report log.txt 2>&1");

 

any additional help is appreciated

 

 

Any guidance with that is appreciated.

I am having difficulty working out how to grab from a URL within a URL a link to an image and display this image on a webpage.
example:

http://domainA.com/page1.php?file_image=http://domainB.com/image.jpg

I know little of this the code below but this is not working:

<?php echo $_GET['file_image']; ?>

this just copies the url, whereas I want to display this image.jpg from domainB using image source by grabing it.
<img src=" ">

I hope you understand me.

I am trying to execute a command line tool, but am having a problem adding a variable to the line.
Here is the code
Code: [Select]
$filename = "devices.txt";
$handle = fopen($filename, 'r');

while (!feof($handle))
{
$devices = fgets($handle, 4096);
$query = 'ipmitool -I lanplus -H 192.168.1.1 -U admin -P adminpass sdr list';
passthru($query);
}
flcose($handle);

On this line I don't want to have the IP manually added like so.
Code: [Select]
$query = 'ipmitool -I lanplus -H 192.168.1.1 -U admin -P adminpass sdr list';

Instead I want to be able to insert the $devices variable which contains the values from the text file so it would look something like this:
Code: [Select]
$query = 'ipmitool -I lanplus -H $devices -U admin -P adminpass sdr list';
Problem is the command line tool does not run this way. How do I properly add the $devices variable so the command line tool ipmitool will run with its value?

Thanks,

I typically only use the first two solutions.  Is there anything wrong with the third?  Is there any more streamlined way to do it?

function f1($x){return $x*1;}
function f2($x){return $x*1;}

$x=2;$y=1;

if(f1($x)>f2($y)){echo(f2($y)."\n");}

// or

$f2_y=f2($y);
if(f1($x)>$f2_y){echo($f2_y."\n");}

// or

if(f1($x)>$f2_y=f2($y)){echo($f2_y."\n");}
