If and Else Statements in PHP

[lindajames]

I have written the following code in asp that makes use of simple If and Else

<%
If Request.Form("transStatus") = "Y" Then
Response.Write "<h3>Success</h3> "

Else
Response.Write "<h3>Cancelled ...</h3> "

End If
%>

Can anyone please tell me how the above is done in PHP?

Cheers
Linda

You might need only 1 = as opposed to 2 ==

<?php
if($transStatus =='Y')
{
print "<h3><Success/h3>";
}
else
{
print "<h3>Cancelled..</h3>";
}
?>

you need both == I believe, just one will set it and it will always return true

[lindajames]

It says $transStatus but how do you define $transStatus?

[ukgimp]

Thats php for you. In the posting of the form you have passed the variable and in php you can just pick it up. The $ delares it so to speak.

You can delare it if you want to but in this case there is no need.

If it data from a form being sent it would be defined by the form. Do you know if you have globals turned on or off? (I am guessing off) you would need to add:

$tranStatus = $HTTP_POST_VARS['transStatus'];

I am guessing its coming from a form.

Yeap thats correct, its coming from a form that uses the POST method not GET

[Knowles]

Sorry its $HTTP_POST_VARS I had it wrong but edited it to fix.

[lindajames]

Thanx Knowles, I will try that out.

One other question. I dont have SSI support on my site, so ive been told to use the PHP include function to include the text file. can anyone tell me how i can include a file with PHP? in SSI its: <!--#include virtual="notes.dat" -->

Cheers

include = "filename.txt";

that should do ya.

[lindajames]

But dont i put no tags to start? like <-- Command --> etc.?

[Knowles]

Not as long as its within the

<?php
?>

tags... anything within those tags will be executed as PHP.

[lindajames]

Can i use the <?php?> tags more than once? for example i execute a PHP command then do a bit of html and then back to PHP

[Gibble]

yes you can go back and forth between php and html

[Knowles]

Sorry I had to update my last post. Yes you can mix and match them:

<?php
if else stuff like that
?>
html stuff
<?php
if else stuff like that
?>

[lindajames]

Thanx Knowles

I tried the following:

<?php

$transStatus=$_REQUEST['transStatus'];

if($transStatus =='Y')
{
print "<h3>Success</h3>";
}
else
{
print "<h3>Cancelled..</h3>";
}

?>

But it doesnt seem to work, i even tried changing the if($transStatus =='Y') to a single = but that way it works but it always returns the success message whether or not the transStatus is Y or not.

Any suggestions would be very much appreciated.

Cheers
Linda

I've seemed to have got it working by changing it to:

if($transStatus =="Y") instead of if($transStatus =='Y')

I guess it was the " can anyone tell me if that was the actual problem?

Cheers

Shouldn't have been the problem. "Y" and 'Y' should both be interpretted as a string litteral consisting of the single character Y. The only difference is that strings in double quotes will be checked for variable interpolation and escape sequences when they are evaluated, and strings in single quotes are only checked for the escape sequence \', which lets you put a single-quote in a single-quoted string.

Do you perhaps have an editor that tries to do "smart" quotes, where the opening and closing double quotes are different? That might result in characters in your source that aren't quotes at all, as far as PHP is concerned. Otherwise, the problem wasn't the quotes.

[Knowles]

$transStatus=$_REQUEST['transStatus'];

I would use:
$transStatus=$_POST['transStatus'];

I have never use $_REQUEST so dont know if it would work or not.
