Quick Fix!! Loops - driving me loopy

[chestnuth]

I have a textbox that contains the following values (A1 A2 A3 A5).

 

How can i loop through it to print each value to the screen on at a time? there maybe different amounts of numbers in the textbox each time. Would i use a for each?

 

Thanks

So, the values are in the textbox and are separated by a single space?

 

<?php

$values = explode(' ', $_POST['fieldname']);

foreach ($values as $value) {

    echo "Value: $value<br>";

}

?>

Yes, seperated by a space!

 

Thanks for that!!

 

However, when i run this code it produces this:

 

Value: A1

Value: A2

Value: A3

Value: A5

Value:

 

and i am left with an empty value at the end, is this to do with my code?

 

<?php

session_start();

if (isset($_SESSION['username']) == false)

{

header("location:login.php");

exit();

}

$values = explode(' ', $_POST['thenames']);

foreach ($values as $value)

{

    echo "Value: $value<br>";

}

//header("location: changecontrol.php?var=change_control.ccid desc&view=1");

//exit();

?>

thanks!!

Replace

<?php
$values = explode(' ', $_POST['thenames']);
?>

with

<?php
$values = explode(' ', trim($_POST['thenames']));
?>

Thanks guys, brill!!

 

i now want to use the id i got from the loop so 'A1' to start with. This will allow me to pick up the contents of the text box with the same name.

 

would i need to use something like this?

echo $_post['.$value.'];

 

or am i on the wrong lines completely?

 

Thanks

Almost correct,

 

you would use

<?php
echo $_POST[$value];
?>

 

BTW, please surround your code with the
