PHP - Problem With Form Output

Hello all!

First, I'm a complete noob when it comes to php coding so bare with me on this. I know this might seem like a super simple thing to do, but as I said I'm a beginner at best.

What I have is a very simple contact form with three fields: name, email, and comments. The way I have it set up is that when someone fills out the form and hits the submit button, it sends me an email via Gmail with the values of the form. Pretty basic stuff.

The thing is, when I get the values in the email, it's all on one line and rather unflattering looking. It works for just me, I don't care really. But I'd like to turn around and use this form/php code I have for a client. The form for them is going to have a lot more input fields and I can only imagine the string of text that it's going to create.

What I would like to do is format the values that I or they receive via email so that it's a bit more presentable.
I have no idea how to do this.

Here's my php code connected to my form:

Code: [Select]
<?php

include_once("phpmailer/class.phpmailer.php");

$name = $_POST['name'];
$email = $_POST['email'];
$comments = $_POST['comments']; 

$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPAuth = true;
$mail->Host = "smtp.gmail.com";

$mail->SMTPSecure = "ssl";
$mail->Port = 465;

$mail->Username = "myemail@gmail.com";
$mail->Password = "xxxxxx";

$mail->AddAddress("mymail@gmail.com");
$mail->From = "mymail@gmail.com";
$mail->FromName = $_POST['name'];
$mail->Subject = "User Comment";
$mail->IsHTML(true);
$mail->Body = "Name: $name\n Email: $email\n Comments: $comments";


if($mail->Send()) {
   echo "Message sent! Thanks for your comments!";
} 
?>


so right now with that I get an email for example that looks like this:

Name: Bob Email: blank@blank.com Comments: I like soda!

where I would rather have something like:

Name: Bob
Email: blank@blank.com
Comments: I like soda!

Any advice would very much appreciated!

Hey Guys,

I've got a section of code that generates a date and time. This is currently standalone however I'm looking to integrate it with a standard page.

This is the code page:

Hello,    I have a problem with the pdf output file from my system.   The code is: <table>

Code: [Select]

    $email      = mysql_real_escape_string(strip_tags($_POST['email']));
    $password   = mysql_real_escape_string(strip_tags(sha1($_POST['password'])));
    $result   = mysql_query("SELECT * FROM users WHERE username='$email' AND password='$password'");

while (mysql_fetch_array($result)) {

For some reason this code outputs a blank screen. It either has to do with my while loop or my if...else statement. Any help?

My output is like this

Thanks in advance: price = prijs, totaal = total, dranken = drinks

I have a form where people enter in values and I need these values displayed in the proper format.  I need the output string to have a "<" at the beginning and a ">" at the end but whenever I put the code in to add the < in the beginning nothing shows up.  Here is my code.  I am able to get it to work with just adding the > at the end but it seems when I add "<" to the beginning this is where nothing shows up.
Code: [Select]
<?php
$hairbald   = trim($_POST['HairBald']);
$eyes   = trim($_POST['Eyes']);

$test =$eyes.'.'.$hairbald;

if(empty($test)) { $test = $test; }
  else
    $test = '<'.$test.'>';
?>
If the user selects blue eyes and bald head I need the output to be <blue.bald>

I am trying to work on a code for php where you first have a form that asks the user to input a message then input a color. When they click the submit button it takes them to the output page.  It should take their message and output it into boxes in a square. And the background should turn the color that they types in.

Hi,   I need to create a landing page with a form. That form needs to be recorded somewhere instead of sent to email. I know I can write it to a SQL database, and then to an excel file. But I only need a temporary solution so I figured I'd just go straight to CSV.    Is this bad practice? What potential problems might I encounter other than security issues?

im testing the following script and it wont send 1 2 3 until the script has finished executing.

What can i do to flush the buffer after every echo statement??

<?php 

echo "1";
ob_flush();flush();
sleep(5);
echo "2";
ob_flush();flush();
sleep(5);
echo "3";
ob_flush();flush();

?>

Hi everyone 

I'm new around here but thought it's about time I joined a good PHP forum! I'll introduce myself properly on the right section, but for now, I'll my post my coding problem on here. I wonder if any has any knowledge or can help.

I'm setting up a connection from my web server to a potential data supplier web server, which involves a load of encryption. One of the stages is generating a SHA1 hash of an encrypted string.

Now I've got some old example code, however the "mhash" function used in this old code appears to obsolete. Thus is doesn't work.

I've tried using the available "sha1" and "hash" functions but cannot replicate the hashed output they provide.

Here's the original code:
Code: [Select]
$encrypted_string = "B0436CBFBC5CAAFB7339AF4A1DF845974D53B9D369146E2E4F1451929D9EBE254363E983F4F94517EB9585FDB112E7B1CCE11A33C5BBA23F8D5DE9D3415BA526489AC796A36FBA76D4293C8DFB673708CED10C9732EEC472D9E43D2626AA104121666E79DD8F2FF6BAC0143BD62E0EE826AF6459779C162613508D48BFE2FC8DD558A1834D7205F96EA8D446E9B371E78E990A3995B1052DCBA9CA0AF99CC77ED2A8B55B2B882BA29D4BB4B07FA91AB4D2F10FBB93732B077335A7E6D96FE813AEDC3711A85CD0C13AE22B28C14FCCE3AF4C1F5D2C0F7697DEC7487CCFC0ED4E77B1B65F39BAD5236E3D3C69D33FC484";

$hashBinaryValue = mhash(MHASH_SHA1, $encrypted_string);
$hashValue = bin2hex($hashBinaryValue);
echo 'hashValue='.$hashValue.'<br>';
The example hashed output should be:
Code: [Select]
31f6d26b18d3c04895cdc2cc05cbd9ad003f2d3e
I cannot seem to replicate this output using the available functions? I've tried the following:
Code: [Select]
$hashBinaryValue = hash('sha1', $encrypted_string);
$hashValue = bin2hex($hashBinaryValue);
And also:
Code: [Select]
$hashBinaryValue = sha1($encrypted_string);
$hashValue = bin2hex($hashBinaryValue);
Both generate:
Code: [Select]
37333736363862393037313732326265346438396433633236383936363430376434613665363231
I've found a webpage that can generate the SHA1 hash, but do not know what language they've done it in.
http://www.fileformat.info/tool/hash.htm?hex=B0436CBFBC5CAAFB7339AF4A1DF845974D53B9D369146E2E4F1451929D9EBE254363E983F4F94517EB9585FDB112E7B1CCE11A33C5BBA23F8D5DE9D3415BA526489AC796A36FBA76D4293C8DFB673708CED10C9732EEC472D9E43D2626AA104121666E79DD8F2FF6BAC0143BD62E0EE826AF6459779C162613508D48BFE2FC8DD558A1834D7205F96EA8D446E9B371E78E990A3995B1052DCBA9CA0AF99CC77ED2A8B55B2B882BA29D4BB4B07FA91AB4D2F10FBB93732B077335A7E6D96FE813AEDC3711A85CD0C13AE22B28C14FCCE3AF4C1F5D2C0F7697DEC7487CCFC0ED4E77B1B65F39BAD5236E3D3C69D33FC484

Any help or input would be greatly appreciated =)

Well I have a script that executes a scan on a system set to run infinitely, and I need it to echo out a message each time it loops through, but I don't want it to echo out the message with the next loop message below it, and the next one below that etc... I've tried using the flush(); function and been messing around with that with no luck. For security reasons I don't want to release any of the processing code, but here is the basic construction of the script:

<?PHP
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
$RepeatIt = -1;
for($g=1; $g!=$RepeatIt+1; $g++)
{
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***

$ScanMessage = ":.:.: SCANNING THE HITLIST FOR MOBSTER: ".$MobName." (SCAN #$g) :.:.:"."<br/><br/>";
echo $ScanMessage;

***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
***PROCESSING AND SCAN CODE***
}
?>

At the moment it's returning:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #1) :.:.:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #2) :.:.:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #3) :.:.:

:.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #4) :.:.:

So what I want it to do is just delete the scanning message and replace it with the next scan message so while running this script you would see just the number increment on the same line.

Any suggestions?

Thanks.

Hello everyone.

I need help with the following PHP APP. I am running on (Version PHP 7.2.10) I am trying to have a page table form on table.php pass the input variable of “5-Numbers” to another page called table_results.php

I want that variable string of “5-Numbers” to be compared against 4 arrays and output any duplicates found within each of those 4 lists. If nothing is found, I still want some visual output that reads “None found”.

 

Lets pretend I have the following example ..

On table.php, I typed inside my table form the 5-Numbers ..

INPUT:  2,15,37,13,28

On table_results.php, the 4 arrays to be compared against my input numbers “ 2,15,37,13,28” are ..

 

$array_A = array(2,6,8,11,14,18,24); 

$array_B = array(1,2,9,10,13,14,25,28,);  

$array_C = array(1,3,7,9,13,15,20,21,24); 

$array_D = array(4,5,12,22,23,27,28,29); 

 

So my output should read as follows below ..

OUTPUT: 

 

TABLE

COLUMN 1   COLUMN 2

ROW 1 Matches Found Results ..

ROW 2 GROUP A:            2 

ROW 3 GROUP B:             2,13,28

ROW 4 GROUP ?            13,15

ROW 5 GROUP ?            28

ROW 6 5#s Input:              2,15,37,13,28

 

Please let me know if anyone has any suggestions on how to go about it. 

Thanks.

Im a having a problem and im thinking maybe i cant do it with php and will have to look into java script
I have several If statements but will only display two of them below. both inputs run on the same button $_POST['build']

the first if statement updates $naqahdah in the database. Its a number being subtracted.
I need the 2nd if statement to grab the new updated naqahdah field in the database before the script reads it.


Code: [Select]
<?php 

if ($_POST['build']) {
if ($_POST['homes']) {

Below here is the php and form i got right now.
What i want to achieve is that when i check a checkbox that the TotalCosts will be updated by the matching value, and when i checked multiple boxes that those vallues will be added together.
But the most important thing what i want to achieve right now is that when you check a box that the TotalCosts echo on the screen will be updated right away with the correct vallues.
I tried some things i found while looking here and on other sites, but nothing seems to be working the way i want.

Anyways, here is my php, i hope someone can help me 


<?php

$hire = 60.00;
$hire1 = 20.00;
$hire2 = 22.50;
$TotalCosts = 0.00;

?>
<form action="index.php" method="post">
<input type="checkbox" name="hire" value="" />Hire <br />
<input type="checkbox" name="hire1" value="" />Hire1 <br />
<input type="checkbox" name="hire2" value="" />Hire2 <br />
</form>

<?php
if (isset($_POST['hire'])) {
$TotalCosts = $TotalCosts + $hire;
}

if (isset($_POST['hire1'])) {
$TotalCosts = $TotalCosts + $hire1;
}

if (isset($_POST['hire2'])) {
$TotalCosts = $TotalCosts + $hire2;
}

echo $TotalCosts;
?>
