More than one input to a form question - how to process?

[smithster]

Finished script just incase it's needed.

<?php 

if(isset($_POST['submit'])){ 

if(@preg_match("/\r/",$_POST['names']))
{
$names = preg_split("/\r/",$_POST['names']);
}
else if(@preg_match("/\n/",$_POST['names']))
{
$names = preg_split("/\n/",$_POST['names']);
}
else
{
$names = @preg_split("/ /",$_POST['names']);
}

 foreach ($names as $thename) {
   echo 'Hi '.$thename.'<br>'; 
 } 
} 
else 
{ 
echo '<form method = "POST" action = "">'; 
echo '<p>Names</p>'; 
echo '<p><textarea rows="10" name="names" cols="37"></textarea></p>'; 
echo '<p><input type="submit" value="Submit" name="submit"></p>'; 
echo '</form>'; 
} 
?>

Great work! By the way, what is the difference between \n and the [\n,] that you had? I don't use preg function very much, so I don't really know much about that stuff.

[smithster]

ok, next part of this! I thought I'd be ok from here but no!! What if I wanted to pair off a username with a password like this.....

user1 : pass1
user2 : pass2
user3 : pass3
and so on...... (without spaces though as : and p together gives a lol)

I thought this would be ok...

 foreach ($usernames as $users && $passwords as $pass){ 

Output....

Parse error: syntax error, unexpected T_BOOLEAN_AND, expecting ')'

Also tried...

 foreach ($usernames as $users || $passwords as $pass){
and also
 foreach ($usernames as $users) && ($passwords as $pass){ 

All give the same error.

Any ideas?

Thanks again,

Smithster.

edit......

almost got it. Slight output problem though....

 foreach ($usernames as $users){
foreach ($passwords as $pass){
$contentusers = ''.$users.':'.$pass.'<br>';
echo $contentusers;
 }
} 

user1 : pass1
user1 : pass2
user1 : pass3
user1 : pass4
user2 : pass1
user2 : pass2
user2 : pass3
user2 : pass4
user3 : pass1
user3 : pass2
user3 : pass3
user3 : pass4
user4 : pass1
user4 : pass2
user4 : pass3
user4 : pass4

I don't have access to my WAMP server, so I can't test this. But try it:

<?php

if(isset($_POST['submit'])){  

if(@preg_match("/\r/",$_POST['names'])) 
{ 
$names = preg_split("/\r/",$_POST['names']); 
} 
else if(@preg_match("/\n/",$_POST['names'])) 
{ 
$names = preg_split("/\n/",$_POST['names']); 
} 

foreach ($names as $thename) { 
   $info = preg_split("/:/",$thename);
   echo "Name: ".$info[0]." Password: ".$info[1].'<br>';
}  
}  
else  
{  
echo '<form method = "POST" action = "">';  
echo '<p>Names</p>';  
echo '<p><textarea rows="10" name="names" cols="37"></textarea></p>';  
echo '<p><input type="submit" value="Submit" name="submit"></p>';  
echo '</form>';  
}  
?>

This is the easiest way I can think of, and it is the closest to your original code.

EDIT: Make sure you get the right one. . . I edited it (had a wrong var name)
I'm not sure if this is what your looking for, but it should work. . .

[smithster]

This isn't going to work.

Here's the script updated with yours added in.

<?php 

if(isset($_POST['submit'])){ 

if(@preg_match("/\r/",$_POST['names'])) 
{ 
$names = preg_split("/\r/",$_POST['names']); 
} 
else if(@preg_match("/\n/",$_POST['names'])) 
{ 
$names = preg_split("/\n/",$_POST['names']); 
}
if(@preg_match("/\r/",$_POST['passwords'])) 
{ 
$passwords = preg_split("/\r/",$_POST['passwords']); 
} 
else if(@preg_match("/\n/",$_POST['passwords'])) 
{ 
$passwords = preg_split("/\n/",$_POST['passwords']); 
}

foreach ($names as $thename) { 
$info = preg_split("/:/",$thename);
echo "Name: ".$info[0]." Password: ".$info[1].'<br>'; 
} 
} 
else 
{ 
echo '<form method = "POST" action = "">'; 
echo '<p>Names</p>'; 
echo '<p><textarea rows="10" name="names" cols="37"></textarea></p>';
echo '<p>Passwords</p>'; 
echo '<p><textarea rows="10" name="passwords" cols="37"></textarea></p>';
echo '<p><input type="submit" value="Submit" name="submit"></p>'; 
echo '</form>'; 
} 
?>

Output....

Name: paul Password:
Name: smith Password:
Name: emma Password:
Name: john Password:

There isn't anything telling it what to do with the passwords and that's the part I'm struggling with.

[Jas]

I didn't know what your form looked like. My way was in the names text box you typed Name:Password. Like Jim:jim99 and the output would be Name: Jim Password: jim99 (in other words you don't need the pw box)

EDIT: Hang on and I'll code it your way

<?php  

if(isset($_POST['submit'])){  

if(@preg_match("/\r/",$_POST['names']))  
{  
$names = preg_split("/\r/",$_POST['names']);  
}  
else if(@preg_match("/\n/",$_POST['names']))  
{  
$names = preg_split("/\n/",$_POST['names']);  
} 
if(@preg_match("/\r/",$_POST['passwords']))  
{  
$passwords = preg_split("/\r/",$_POST['passwords']);  
}  
else if(@preg_match("/\n/",$_POST['passwords']))  
{  
$passwords = preg_split("/\n/",$_POST['passwords']);  
} 

for($i=0; $i<count($names) || $i<count($passwords);$i++){
echo "Name: ".$names[$i]." Password: ".$passwords[$i];
}  
}  
else  
{  
echo '<form method = "POST" action = "">';  
echo '<p>Names</p>';  
echo '<p><textarea rows="10" name="names" cols="37"></textarea></p>'; 
echo '<p>Passwords</p>';  
echo '<p><textarea rows="10" name="passwords" cols="37"></textarea></p>'; 
echo '<p><input type="submit" value="Submit" name="submit"></p>';  
echo '</form>';  
}  
?>

Try that. Your way had a loop within a loop. This is one loop that does both at the same time.

[smithster]

Thank you Jas, getting there now!!

Changed it slightly to output each one on a new line.

for($i=0; $i<count($names) || $i<count($passwords);$i++){ 
echo ''.$names[$i].':'.$passwords[$i].'<br>'; 
} 

Problem!
The output...

user1:pass1
user2: pass2
user3: pass3
user4: pass4 

The phpcode under output is actually supposed to be a quote, but it puts a : and the p together to make emoticons!!!

For some reason, the 1st 1 is correct as I want it. But the rest all have a space between the : and the password. Why is this?

[Jas]

EDIT: try

echo "Name: ".preg_replace("/ /","",$names[$i])." Password: ".preg_replace("/ /","",$passwords[$i]); 

EDIT 2: You might also try:

echo "Name: ".preg_replace("/ /","",$names[$i],1)." Password: ".preg_replace("/ /","",$passwords[$i],1);
//The 1 at the end makes sure only the first space is removed. Might me advantageous, may not be. 

EDIT 3: Better idea! Try this:

if(@preg_match("/\r/",$_POST['names']))   
{   
$names = preg_split("/\r /",$_POST['names']);   
}   
else if(@preg_match("/\n /",$_POST['names']))   
{   
$names = preg_split("/\n /",$_POST['names']);   
}  
if(@preg_match("/\r /",$_POST['passwords']))   
{   
$passwords = preg_split("/\r /",$_POST['passwords']);   
}   
else if(@preg_match("/\n /",$_POST['passwords']))   
{   
$passwords = preg_split("/\n /",$_POST['passwords']);   
} 

[smithster]

Still exactly the same output.

On both of them. 1st is perfect. Anything after that has a space before the password and there shouldn't be!!!

[Jas]

Hmm. . . I am away from wamp right now, so it's hard to figure out lol. Try the last edit I made on my previous post. Probably won't work though. I might have to look at it later. It must be from the \n or \r because it doesn't effect the first. You could try:

echo "Name: ".preg_replace("/\n/","",$names[$i])." Password: ".preg_replace("/\n/","",$passwords[$i]); 

If that works I can give you a more effective solution later
