PHP - Remove A Message Printed On Screen

So I have been printing out some debug information, and now I am trying to instead save it to a string, which I will print out at the end of the page. Here is some specific problematic code:

$myplugin_debug_test.= "\n[GETTING COOKIES...\n";
$myplugin_debug_test.= print_r($myplugin_all_cookies);//THIS IS LINE 38
$myplugin_debug_test.= "\n... DONE]<br/>\n";

However, when I do this I get the following error:

Quote

Warning: Cannot modify header information - headers already sent by (output started at ...:38


So my question is how can I output the array data into a string, so that I can print it out later.
Like what am I doing wrong? Is there a better way to do this?

Thanks!

I'm trying to show on my order printed receipt some checkout fields and extras from the products.

The website is www.prontoitaliano.co.uk/shop

What needs to appear on the receipt are all the extras options from all the products(See checkboxes in all pasta dishes and checkboxes toppings in "create your own pizza") and 2 fields from the checkout page (Pick up Date, Pick up Time).

To send the order to the printer I'm using the "Star cloud PRNT woocommerce" plugin and for the pickup date and time fields "ultimate woocommerce delivery and pickup date time", I've attached below the code that needs to be edited to add more fields to the receipt. I know that probably it's not difficult to solve my issue but I don't have any knowledge of php and I hope you guys can assist me. Also, I've attached a picture showing what is missing on the printed receipt and what result I'm trying to get. Thanks for your time!

First problem fixed.
My second problem is if the result is 0X.XX,0 or 0X.XX,1 I would like to remove the first 0
The X.XX are numbers, but the 0 is not always there.

Can anyone help please
Thanks

Hey Guys,

I have followed a tutorial and got a SMS text message script working. Although what i would like to do now is allow a registered user to add another user via a form. This form will contain the users mobile number, email, who its from,  and a textarea for the message to send to them in the text message.

*** It also stores it into a database. But dont worry about that.

I have run into a problem, when i type in a mobile number and an email address and then press send. It doesnt seem to store the email address in the $vars echo (message). **It does echo in the email bit but i wont it to show in the message bit. **

Here is a screenshot.

right ive setup my own messaging feature on my website but it still allowes me to message myself if tried

Basically, All I want to do is save a .txt (doesn't have to be .txt) to my FTP and PHP simple echos it. The .txt is where a message is stored. But when I write the message my self like this:
Hello

This is a message.

- And then upload it to my FTP, PHP echos it like this "HelloThis is a message". Is there anyway for PHP to notice the 'white space'?

--OR--

If you know of a better way to make a message system, then also let me know

Thanks, Ollie!

Along the same lines as a "Thank you for you submission" message, is there a simple way to echo the CHANGES made to a record AFTER it has been UPDATED.

For example: You have added 2 skirts and 1 shirt to your order
OR       You're order has been reduced by 2 pair of socks.

This would compare what was stored with the change.

Alternately, is there a way to show a message that ONLY addresses the values that have CHANGED as a result of the UPDATE.
Example:  You have altered the quantity of the following items: dresses, hats, gloves.

im trying to get new user messages to show up on my site.. i have looked around on google but can only find info on popup alerts.. i just need a simple javscript code that will display the number of new messages next to the link that takes them to their inbox.. if someone could point me to a site or if they have the code handy i would appreciate it more than you know.. thank you

I am looking for someone that would be willing to provide the code for a message box that will popup after a PHP file upload completes.  It will simply display a message stating that the upload is complete.  Thank you in advance for your assistance.

Code: [Select]
switch($_GET['action']){
case 'write_ok':

$error=false;

$msg='';

if($_POST['dateofbirth']=='' || !preg_match( "/^(19|20)\d\d[-\\./](0[1-9]|1[012])[-\\./](0[1-9]|[12][0-9]|3[01])$/",$_POST['dateofbirth'])){
$error=true;
$msg.='Date of birth is required and in the correct format 00/00/0000\n';

}

the message at the end appears if the error is true. I wanted to know how to not show an errors message if the error is false. Any help on this?

Can anyone help me with this delete confirm box. I have tried but somehow its not working. Can anyone help me with this?

Thankz.

html codes :


echo "<td><a href=delete.php?id=" . $rows['id'] ." onclick=\"return confirm(Are you sure?);\">Delete</a></td>";


delete.php :


<?php
include "config.php";
?>

<?php
 $id=$_GET['id'];
?>

<script type="text/javascript">
<!--
function confirmation() {
    var answer = confirm('Are you sure you want to delete?')
    if (answer){
        $sql="DELETE FROM document WHERE id='$id'";
    }
    else{
        alert("Cancelled the delete!")
    }
}

</script>
