<?php

session_start();

	$entries = explode( "\n", $_POST[my_textarea]);
    
	$x=0;
    
	foreach($entries AS $entry)
    {
        
		if($entry!=="")
        {
        
			$register_sql = "INSERT INTO emails(emails_email) VALUES ('$entry')";	
			$register_row = mysql_query($register_sql);	

	        echo "$entry added to database<br>";

i have the above code, where you enter emails in a textarea like

 

[email protected]

[email protected]

 

and then it will put them into my database.

 

right now what i want to do is adapt the above code to do the same when you put emails in the textarea like..

 

[email protected]; [email protected]

 

thanks in advance

use str_replace to find and replace any ";" with "\n". Continue to use your explode function to break the email addresses apart on "\n".

 

Then, use trim() to remove any unwanted white-spaces for each email address.

[ironhamster88]

<?php
if(strpos($_POST['email'], ';')) {
// break string into array by semicolons
$arr = explode(';', $_POST['email']);

// loop through the array of emails
foreach($arr as $email) {
	// remove any spaces in the email address (if the user has used ; followed by a space to separate emails)
	$email = trim($email);
	// insert $email into database
}
} else {
// normal insert functions for singular emails
}
?>

That would work only for a email addresses separated by ";", and not "\n".

 

I believe the OP was looking for a solution to do both at the same time? 

 

[email protected];[email protected]
[email protected]

 

either way, just add this line in ironhamster's code for both to work:

$_POST['email'] = str_replace(";", "\n", $_POST['email']);

like this...

 

	{
    
	$entries = explode( "\n", $_POST[my_textarea]);
    
	$entries = str_replace(";", "\n", $entries);

	$x=0;
    
	foreach($entries AS $entry)
    {
        
		if($entry!=="")
        {
        
			$register_sql = "INSERT INTO emails(emails_email) VALUES ('$entry')";	
			$register_row = mysql_query($register_sql);	

	        echo "$entry added to database<br>";
	        $x++;
        
		}
    
	}
