[Breaking Out of a foreach loop with header("Location: $self");]

both snippets of code will work.

 

and yes, you can "break" out of a loop using a header() redirect.

 

are you setting $self?

 

BUT, the first snippet isn't working at all and the second one is.

[Breaking Out of a foreach loop with header("Location: $self");]

Is the answer that you can't escape out of a foreach() loop with the header() function?

[Get line number (text file)?]

Hi,

I have a text file such as:

Tab1a||Tab2a||Tab3a
Tab1b||Tab2b||Tab3b

 

Now when i display this data, i want to display the line number next to it (i.e. Tab1b... line 2)

How would i do that?

Thanks

 

One way would be:

 

$rows = @file("/path/to/filename.ext");
foreach($rows as $key=>$value){
$row = $key+1;
echo $value." line ".$row."<br />";
}

[Breaking Out of a foreach loop with header("Location: $self");]

Am I correct?

 

No.

 

The issue is that this (psuedo) code doesn't work:

 

$rows[ ] = "eawf:otherstuff\n";
$testdata = "eawf";
foreach($rows as $row){
$data = explode(":",$row);
if($data[0] == $testdata){
  header("Location: $self");
}
}

 

while this one does work:

 

$rows[ ] = "eawf:otherstuff\n";
$testdata = "eawf";
foreach($rows as $row){
$data = explode(":",$row);
if($data[0] == $testdata){
  $flag = true
}
}
if(isset($flag)){
  header("Location: $self");
}

 

actually does work.  So the question is, WHY doesn't the first code snippet work?

 

The psuedo code for the above is:

 

Form submit provides input vars for userid and password.
read all records from .htpasswd and load to an array ($rows)
process array one element at a time
parse array vars via ":" character.
if userid from form matches the userid from .htpassword:
  reload the page with a get var loaded with an error message.
else process next record.

 

I can[t find anything online indicating that the foreach loop is not able to be broken by issuing the header() function, which, at least to my way of thinking, should stop program code execution by simply reloading the page again.  What ends up happening is that the program continues to run and the header statement is not executed.

 

Hope this makes sense?

You're not returning a true/false statement in your second code.

 

Am I missing something.  The if statement is exactly the same.  Shouldn't the condition being true kick in the header statement which would reload the page with the error message passed in the get?

 

 

Also, you're using a header to redirect, which only works if the browser hasn't received data yet (if the header has been established).

 

 

Yeah, I checked that previously to verify that headers weren't being sent, and they're not, PLUS that doesn't explain why the header statement works below the foreach loop, right?

 

I till try again with the settings turned on to see if there's something generated.

[Breaking Out of a foreach loop with header("Location: $self");]

Code produces no error messages in the log or on screen.

 

The if condition passes as if it returns false.  Note that the same if condition passes as true on the first bit of code.

 

IOW: header() statement works as expected in the first code and doesn't work at all in the second snippet.

[Breaking Out of a foreach loop with header("Location: $self");]

I have an administrative back end on a secure server that I want to use Basic Authentication for.

 

In my "Add" module, I can't figure out why this works:

$rows = file($passfile);
import_request_variables("gp","x_");

switch($x_action){
  case "Add":

...

   foreach($rows as $row){
    $data = explode(":",$row);
    if($x_userid == $data[0]){
     $dupe = 1;
     $errormsg = "Duplicate Record!";
    }
   }

...

   if($dupe == 0){
    write_rows($passfile,$rows);
    header("Location: $self");
   }else{
    header("Location: $self?errormsg=$errormsg");
   }
  break;

...

 

and this doesn't:

 

$rows = file($passfile);
import_request_variables("gp","x_");

switch($x_action){
  case "Add":

...

   foreach($rows as $row){
    $data = explode(":",$row);
    if($x_userid == $data[0]){
     header("Location: $self?errormsg=Duplicate Record!");
    }
   }

...
  break;

 

Thanks in advance for your constructive comments.

[connection problem]

Check your Error Logs for the actual PHP error.

Also, instead of writing the connect code, use Justin Vincent's ez_SQL database wrapper. Makes database interactions rediculously simple.

[PostgreSQL SECURE CONNECTION - PHP]

Check out Justin Vincents "ez_sql" database wrapper class, modify it for PostgreSQL(only takes a couple lines), and then check out how it all works. It will ultimately save you LOTS of headaches, and database can be anywhere, ssl or not.

 

HTH!
