Hi,
First of all I don't know a lot of php just enough to get myself in trouble as I have now.
I have a php form where I have 7 error messages on fail.
I have the following in my form page:
session_start();
$_SESSION['errmsg'];
----------------------------
error messages under separate if statements.
$errmsg = 1;
header ("location: msg.php?errmsg");
$errmsg = 2;
header ("location: msg.php?errmsg");
$errmsg = 3;
header ("location: msg.php?errmsg");
$errmsg = 4;
header ("location: msg.php?errmsg");
$errmsg = 5;
header ("location: msg.php?errmsg");
$errmsg = 6;
header ("location: msg.php?errmsg");
$errmsg = 7;
header ("location: msg.php?errmsg");
(i didnt fill in the actual messages yet just testing)
Then in my msg.php file i have:
session_start();
$_SESSION['errmsg'];
if($_SESSION[errmsg']==1){
$errmessage = "message 1";
}
if($_SESSION[errmsg']==2){
$errmessage = "message 2";
}
if($_SESSION[errmsg']==3){
$errmessage = "message 3";
}
if($_SESSION[errmsg']==4){
$errmessage = "message 4";
}
if($_SESSION[errmsg']==5){
$errmessage = "message 5";
}
if($_SESSION[errmsg']==6){
$errmessage = "message 6";
}
if($_SESSION[errmsg']==7){
$errmessage = "message 7";
}
<html>
<span class="content"><h3>Message:</h3></span>
<p class="content"><h2>$errmessage</h2></p>
Currently I am getting an error in msg.php:
Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ']'
on the following line: $errmessage = "message 2";
Thank you for any help.

Hi there Gibsongk55,
Welcome to the forums!
Your error is just a typo on all of the if clauses:-
if($_SESSION[errmsg']==1){ <<-- this line on each clause
$errmessage = "message 1";
}
Should be:-
if($_SESSION['errmsg']==1){ <- the extra ' is really needed there
$errmessage = "message 1";
}
Realistically you need to check to see if the variable isset() and !empty() before putting a conditional clause around it.
Hope that makes sense.
Cheers,
MRb

Hi Matthew,
Thanks for the help. I can't believe i missed that. Well that worked but now I have a problem showing the error message on the php page its passed to.
when the msg.php page loads it shows nothing, no error message.
I tried this:
<p class="content"><h2><?php echo $errmessage;?></h2></p>
Nothing shows up at all.
Thanks,
Gibs

Thanks for the help i finally got it figured out.
Under my error messages "if" statements in the php form I had to change the line to the following:
$errmsg = 1;
header ("location: msg.php?errmsg");
new line:
$_SESSION['errmsg'] = 1;
header ("location: msg.php?errmsg");
Thanks again for the help.
