to clarify, you have a <textarea> form field where people enter several items and you want each of those items to be put in an array? Are the items always seperated by a carrage returns (ie, does the user hit the "enter" or "return" key while typing to seperate each item? if so

$my_array = explode("\n",$_POST['text_area_name']); // "\n" means line break

print_r($my_array); //ta-da!

tartou2 · October 27, 2010

ok that can replace lots of code but there is still a problem

i used this code

$abc = explode("\n",$_POST['name_list']);
$names = array($abc[0],$abc[1]);
echo $names[0];
echo $names[1];

and i typed 2 names in the textarea each on a line example:

test1

test2

the script is only showing the first name. I mean:

test1

How can i make it to show the second name?

rwwd · October 27, 2010

$abc = explode("\n",$_POST['name_list']);
$names = array($abc[0],$abc[1]);
//print the array to screen
print_r($abc);
echo "<br>";
print_r($names);

See what those array's hold first..

this is what the arrays are holding:

Array ( [0] => test1 [1] => test2 )
Array ( [0] => test1 [1] => )

$names arrays doesn't seems to handle more then one value

tartou2 · October 27, 2010

this seems a series of errors appearing one after another.

ok i have used this code:

//$abc = explode("\n",$_POST['name_list']);
$names = explode("\n",$_POST['name_list']);
//print the array to screen
//print_r($abc);
//echo "<br>";
print_r($names);

and i got this:

Array ( [0] => test1 [1] => test2 )

which is good but a new problem appears now.

this is a part of a code that is being used in this page:

foreach($results as $name=>$result) {
  if ($result) {
    echo $name.' is valid<br>';
  } else {
    echo $name.' is not valid<br>';
  }
}

but the it shows only the last array value stored in $name array:

test2 is valid

How to make all array values to show after been validated because if i enter the array value manually, I mean like this:

$names = array('test1','test2');

I can see all names been validated, I mean i can see this:

test1 is valid
test2 is valid

How to solve this :confused:

You need to specify exactly what you are trying to do and paste your source code in it's entirety.

First you say, text file, then it's textarea. Your vars are $abc then $names and now we are dealing with an array called $results.

How is this array created? What does that contain? You need to clearly illustrate how we get from a textarea to $names, then to a loop for $results.

With that, can answer you question no problem.

ok the script is a email validator that validate more then one email at the same time.

emails are collected from the textarea feild.

Here is the code of the script and i hope you can fix the problem so it can validate all emails:

<html>
  <head>
   <title></title>
   <style type="text/css">
    body{
    background-color:#1166aa;
    }
   #mainbox{
   width:inherit;
   background-color:#FFFFFF;
   padding:14px;
   border:solid 3px #000000;
   float:left;
   }
   #mainbox2{
   background-color:#CCCCCC;
   border:solid 2px #000000;
   padding:11px;
   }
   #contaner{
   border:solid 0px #00FF00;
   }
   h1:hover{
   color:#0000CC;
   cursor:pointer;
   }
   #msg{
   cursor:pointer;
   }
   table td{
   border-top:outset 1px #999999;
   }
   #amount{
   color:#FF0000;
   cursor:crosshair;
   }
   #to{
   color:#3300FF;
   }
   #from{
   color:#3300FF;
   }
   #subject{
   color:#3300FF;
   }
   </style>
  </head>

The script show only the last email entered to be validated

Anti-Moronic · October 27, 2010

This line could be causing the problem:

$results = $SMTP_Validator->validate($emails, $sender);

Does the validator accept and array of $emails?

If it does, would need to an array output of $results to determine.

tartou2 · October 27, 2010

yes the validator accept arrays

and this the results shown on the page using these emails:

test1@gmail.com

test2@hotmail.com

Array ( [0] => test1@gmail.com [1] => test2@hotmail.com ) test2@hotmail.com is valid

it only validate the last email but if i don't use the textarea feild and i enter the emails manually into the array, i mean like this:

$emails = array('test1@gmail.com','test2@hotmail.com');

the script validate both emails

Anti-Moronic · October 27, 2010

Right, I see. Sorry - yeh, it's the way the array is being created. It is not capturing the textarea values.

Ya know what, do you have instant messenger, the html and the class for validation? I'll gladly take a look because it's starting to frustrate me too

If $names holds all your values but doesn't return valid for all..

..and when you manually construct the $names array, it returns valid for all..

Something is not right.

tartou2 · October 27, 2010

I sent you my email in a PM

Anti-Moronic · October 27, 2010

Fixed

tartou2 · October 28, 2010

a huge part of the problems are fixed and thank you for helping me but a new problem appears.

It doesn't validate emails with special caracters.

I already sent you an email on your messenger inbox.
